All details about the manufacture of vortex heat generators with their own hands

Do you want to increase the energy efficiency and coziness of your house? The fascinating realm of vortex heat generators is the only place to look. These clever gadgets are becoming more and more well-liked among do-it-yourselfers and environmentally conscious homeowners. We’ll cover all the information you require to build your own vortex heat generator at home in this guide.

Let’s first examine the definition and operation of a vortex heat generator. In essence, it’s a device that effectively transfers heat by utilizing vortices, which are those whirling, tornado-like patterns of air. These generators heat water or air very effectively by generating controlled vortices inside a specially made chamber. It’s a straightforward idea with great potential to completely change the way we heat our houses.

Now, you may be asking yourself, "Why bother?" since you can easily purchase a vortex heat generator off the shelf. To begin with, building your own generator can be a fulfilling do-it-yourself project that you can tailor to your needs and budget. It’s also a fantastic way to see the principles of fluid dynamics and thermodynamics in action.

It’s important to comprehend the fundamental parts involved in vortex heat generator construction before getting too technical. Every component, including the heat exchanger, vortex chamber, controls, and safety features, is essential to guaranteeing both safety and optimum performance. If you’re not familiar with all the technical jargon, don’t worry; we’ll translate it into plain, understandable language.

How to make a generator yourself

Potapov invented the first tubular unit. However, he was not granted a patent for it, so as of right now, the ideal generator’s justification is deemed insufficient. In reality, Schauberger and Lazarev attempted to replicate the device as well. Working on the drawings of Larionov, Fedoskin, Petrakov, and Nikolai Zhuk is currently accepted.

Prior to beginning work, select a vacuum or proximity pump based on its specifications (suitable even for wells). For this reason, the following elements need to be considered:

1. Pump power (a separate calculation is made);
2. Required heat energy;
3. The size of the head;
4. Pump type (up or down).

Even though there is a vast array of shapes and types of cavitators, the most common and practical form for industrial and household devices is the nozzle. Furthermore, because it is simple to update, the generator’s power is greatly increased.

Examine the cross-section of the opening between the diffuser and confuser before beginning any work. It should be between 8 and 15 cm wide, neither too wide nor too narrow.

In the first scenario, you will raise the working chamber’s pressure, but the power won’t be very high, meaning that the volume of heated water will be smaller than that of cold water. Along with these issues, a slight variation in cross-sections contributes to the oxygen saturation of incoming water from the working branch; this indicator influences the pump’s noise level and the likelihood of cavitation phenomena occurring within the device, both of which could have a detrimental effect on the device’s operation.

Expansion chambers are an absolute necessity for cavitation heat generators in heating systems. Depending on the demands and the required capacity, they may have distinct profiles. The generator’s design may vary based on this factor.

Help from a cavitation heat generator

Internal combustion engine use is causing a significant change in the climate today. Transportation accounts for forty percent of the carbon dioxide emissions on Earth, with a large portion coming from residential fuel burning for heat. This process releases several toxic substances into the atmosphere, disrupting the planet’s natural equilibrium. For these reasons, TPP energy is not recommended as a sustainable substitute.

Cavitation heat generators allow you to solve some of the complexities in an obvious way: pumping energy from a part of space to another, it will be possible to solve the urgent needs of human activity. For example, a generator can give heat and take away heat. The key advantage of heaters is that the energy does not disappear without a trace. It remains heat on the ohmic resistance of wires, overcomes the forces of friction. Everything happens around the power plant, eventually lost by parasitic effects, unused due to disparate factors. Cavitation generator will allow to collect the lost crumbs by a simple method: it will start pumping heat from the center of its formation:

1. Engine windings.
2. Friction surfaces.

The plant’s efficiency will already rise as a result of this factor—heat losses warm the area where heat is pumped. It’s definitely a plus. We’ll take the remainder from the air. It’s important to think about:

• A refrigerator warms the kitchen in the summer, efficiency drops.
• The air conditioner takes the heat from the cold or pumps out the cold from the sunny side of the building.

And cavitation heat generator is able to utilize its own losses to its advantage. It must be recognized as promising. The difficulty is how to get more bubbles out of mechanical motion. Dozens, if not hundreds of patents are already devoted to it today, for example, RU 2313036. It is not difficult to guess that for pumping heat must be taken from somewhere. This is the right way to put it, because of missing the point of what is going on people don"t want to believe that the cavitation generator is a reality: "As a heat engineer, I"ll tell you – it"s nonsense. Energy does not come out of nowhere. Spend less electricity and get more heat allows heat pump." (okolotok forum.ru)

If an expert is unsure that we are discussing a specific type of heat pump, what does the general public understand about cavitation heat generators? Now let’s see who stands to gain from the cavitation heat generator. Using the refined design, you can:

1. For wastewater energy extraction.
2. Cooling of workshops with simultaneous heating of workplaces.
3. Heating of premises without the use of oil, gas, fuel oil, coal, wood, etc.

Rotary heat generator

What is a rotary heat generator?? In essence, it is a slightly modified centrifugal pump, i.e. there is a pump casing (which in this case is the stator) with inlet and outlet connections, and a working chamber, inside of which there is a rotor, which acts as an impeller. The main difference from a conventional pump lies precisely in the rotor. There is a great variety of rotor designs of vortex heat generators, and we will not describe all of them, of course. The simplest of them is a disk, on the cylindrical surface of which a lot of blind holes of a certain depth and diameter are drilled. These holes are called Griggs cells, after the American inventor who was the first to test a rotary heat generator of this design. The number and size of these cells is determined based on the size of the rotor disk and the speed of the electric motor driving it into rotation. The stator (a.k.a. the heat generator housing) is usually made in the form of a hollow cylinder, i.e., a rotor.е. A pipe plugged on both sides with flanges The gap between the inner wall of the stator and the rotor is very small and is 1…1.5 mm.

The water is heated in the space created by the rotor and stator. Its friction on the rotor’s and stator’s surfaces, together with the latter’s quick rotation, make this possible. Naturally, cavitation processes and water swirls in the rotor cells also contribute significantly to the heating of the water. Typically, the rotor has a 300 mm diameter and rotates at 3000 rpm. The rotational speed must be increased when the rotor diameter reduces.

It is easy to assume that even with its simplicity, a construction of this kind needs a fairly high level of manufacturing precision. Of course, the rotor will also need to be balanced. Furthermore, rotor shaft sealing is a problem that needs to be resolved. It goes without saying that the sealing components need to be changed on a regular basis.

It is evident from the foregoing that there is not much of an installation resource. Rotating heat generators produce a lot of noise when they operate, among other things. Despite having a capacity that is 20–30% greater than static heat generators. Heat generators of the rotary type can even produce steam. But is this better than static models in the event of a short service life?

Let"s consider the design of the generator

1. The water inlet pipe 1 is connected by means of a flange to the pump, the essence of which is to supply water under a certain pressure into the working chamber.
2. Once the water enters the spigot, it must acquire the proper velocity and pressure. This requires specially selected pipe diameters. Water moves quickly to the center of the working chamber, reaching which the mixing of several streams of liquid is carried out, after which the energy head is formed;
3. A special braking device is used to control the fluid velocity. It should be installed at the outlet and outlet of the working chamber, it is often done so for oil products (oil waste, recycling or flushing), hot water in the household appliance.
4. Through a safety valve, the liquid advances to the opposite branch pipe, where the fuel is returned to the starting point by the operation of a circulation pump. Due to constant motion and produces heat and heat that can be converted into constant mechanical energy.

The operation is, in theory, straightforward and works on a similar principle to the vortex device; in fact, the formulas used to determine the heat produced are the same. That is:

Where the Sun’s kinetic, non-constant motion is expressed as Ekin = mV2/2;

The planet has a mass of m kg. released on econet.ru

Types of cavitation heating boilers

The process of making cavitators is fairly intricate. It can happen in a number of ways. Heat generators are categorized based on how cavitation forms.

Cavitation heat generator types:

1. Rotary type heat generator very similar in principle to the centrifugal pump. Here, the pump casing is the stator into which the pipe is installed. There is also a chamber with a rotor spinning like a wheel. The rotor resembles a disk and has a lot of holes, the number of which is related to its capacity. This disk is placed in a pump casing sealed on both sides. Due to the holes in the router and its rapid rotation and create cavitation bubbles. The design of such devices is not ideal, they have low efficiency and a small service life.
2. Static heat generators They have no rotating parts. Nozzles are used to recreate cavitation. Here, a centrifugal pump feeds the water flow into the nozzle, it passes through several elements and exits through the last one with the narrowest opening. Once out of the narrow opening, the water expands rapidly and cavitation bubbles with gas inside are formed. Thanks to this, the water is heated. This model has a longer service life than a rotary heater, but has an even lower efficiency rating.

There are flaws in both types of cavitation boilers. Their service life is short and their efficiency is low. Still, the concept of this kind of boiler intrigues me greatly. Maybe it will soon be completed and made public.

This type uses fuel, like electricity, to function. But because it consumes little energy, its advancements appear quite promising.

Heat generators are highly complex devices. Nonetheless, you can make it by hand if you have a strong mathematical mind and artistic drawing abilities.

Pros and cons of cavitation energy sources

Simple devices called cavitation heaters transform the working fluid’s mechanical energy into thermal energy. Actually, the low efficiency index centrifugal pump used in private homes’ water supply systems, baths, and wells is what makes up this apparatus. In industrial plants, where heating elements can be seriously damaged by contact with the working fluid that has a significant temperature difference, energy conversion in a cavitation heater is widely used.

The cavitation heat generator’s design

Advantages of the gadget:

1. Efficiency;
2. Economy of heat supply;
3. Availability;
4. It is possible to assemble with your own hands a home device for the production of thermal energy. As practice shows, a homemade device is not inferior to a purchased one in its qualities.

Drawbacks of the power source:

1. Noisiness;
2. It is difficult to get materials for production;
3. The power is too large for a small room up to 60-80 square meters, a household generator is easier to buy;
4. Even mini units take up a lot of space (on average at least one and a half meters of a room).

Operational concept

Since the word "cavitation" describes the creation of bubbles in a liquid, the impeller works in a mixed phase environment during the liquid and gas bubble period. Pumps are typically not made for the mixed flow phase because they burst bubbles during operation, which reduces the cavitation generator’s efficiency. The purpose of these thermal fixtures is to create mixed phase flow through fluid agitation, which will lead to thermal conversion.

Commercial cavitation heaters work by using mechanical energy to drive an input energy heater (such as a motor or control unit), which forces the fluid that produces the output energy to return to its source. Because of this conservation, mechanical energy is converted into thermal energy with a negligible loss (typically less than 1%), and conversion errors are factored into the conversion computation.

The operation of a supercavitation reactive power generator differs slightly. These heaters are found in strong plants where the fluid’s power increases significantly over the amount of mechanical energy needed to run the heater when the output’s thermal energy is transferred to it. The fact that these gadgets don’t need to be inspected and adjusted on a regular basis makes them more energetically productive than return mechanisms.

These generators come in various varieties. The most prevalent kind is the rotary-hydrodynamic mechanism developed by Griggs. Its working theory is derived from how a centrifugal pump functions. It is made up of a working chamber, housing, stator, and spigots. While there are numerous modernizations available today, the most basic is a drive or disk (spherical) water pump that rotates. Griggs cells are the structural elements that have numerous blind holes (no escape) drilled into a disk-shaped surface. Their dimensional parameters and number are directly influenced by the drive’s speed, the heat generator’s design, and the rotor’s power.

Griggs hydrodynamic process

A certain amount of space is required between the rotor and stator in order to heat the water. The quick movement of liquid on the disk’s surface, which adds to the temperature rise, carries out this process. The rotor rotates at about 3000 rpm on average, which is sufficient to bring the temperature up to 90 degrees Celsius.

A static generator is the term used to describe the second kind of cavitation generator. It lacks any rotating parts, in contrast to the rotor, and requires nozzles for cavitation to occur. These are specifically the sections of the well-known Laval that are attached to the working chamber.

In order for the generator to function, a standard pump must be connected. Just like with a rotary generator, this pressurizes the working chamber, increasing the temperature of the water and facilitating faster water movement. The difference in diameter between the progressive and outlet nozzles provides the liquid velocity at the nozzle outlet. Its efficiency is significantly lower than that of a rotary, and it is also heavier and more dimensional.

Scope and types of thermoelectric generators

There are still two applications due to the TEG’s low efficiency:

1. In places where other sources of electricity are not available.
2. In processes where there is excess heat.

Here are a few instances of these gadgets.

Energy furnace

Devices and data combining the following capabilities:

• Cooking surface.
• Heater.
• Electricity source.

It is a great illustration of combining the two uses.

Indigirka: a triad combined

The following characteristics of the energy heater depicted in the image are:

• Weight – just over 50 kilograms (not including fuel).
• Dimensions: 65x43x54 cm (with disassembled chimney).
• Optimal loading of orgfuel is 30 liters. It is allowed to use hardwood, peat, borax (not stone wood)!) coal.
• The average heat output of the device is about 4.5 kW.
• Electric load power from 45-50 W.
• Stabilized constant output voltage – 12 V.

As you can see, these parameters work quite well in situations without gas, heating, or electricity. With an adapter from the car cigarette lighter, the little electric power is more than sufficient for powering other gadgets or charging mobile devices.

Radioisotope TEGs

Thermal energy released during the decay of unstable elements can be used as a heat source for thermoelectric generators. We refer to these sources as radioisotope sources. Their primary benefit is that they don’t require ongoing fuel loading. The requirement for ionizing radiation protection, the impossibility of refueling, and the requirement for disposal are drawbacks.

The fuel’s half-life directly affects how long these sources will last in service. The latter is contingent upon the requirements listed below:

• High volumetric activity coefficient, i.e. a small amount of the substance should provide the required level of energy release.
• Maintaining the required power level over a long period of time. As it was mentioned above, this parameter is affected by the half-life, for example, strontium-90 has a half-life of 29 years, so the source will lose half of its power after this time.
• The ionizing radiation must be easy to dispose of, i.e. it must be dominated by α-particles.
• Required level of safety. That is, ionizing radiation should not harm the environment (in case of operation on the ground) and the equipment powered by such a source.

These criteria are met by the isotopes of strontium-90, curium-244, and plutonium-238.

Scope of application of RITEG

Although these sources have strict requirements, they have a wide range of applications and are utilized both on Earth and in space. The RITEG that worked on the Cassini spacecraft is depicted in the picture below. As fuel, plutonium-238 isotope was employed. This element has a half-life of slightly over 87 years. After a 20-year mission, the source generated 650 W of power.

The radioisotopic "heart" of Cassini.

Although Cassini was used as an example, it can be said that almost all satellites use RITEG to power their equipment in terms of mass. Regretfully, there is typically no publication of the properties of radioisotope spacecraft power sources.

The situation is roughly the same on the ground. Although RITEG technology is somewhat known, its specifics are still under wraps. It is a well-established fact that these devices are utilized to supply power to navigational aids in locations where alternative means of obtaining electricity are impractical due to technical constraints. That is, we are discussing areas that are difficult to access.

Regretfully, from an environmental perspective, these sources are not the best substitute for thermal power plants.

From a 14-meter depth, RITEG was recovered close to Sakhalin Island.

Vortex heat generators

The purpose of TC1 heat plants is:

Thermal plant	Energy consumption per season(210 days)	Cost of heating 1 sq. м. per year in rubles
Gas boiler "kchm" – 96 kW	46 200 cu. m. m gas	46,29
RUSNIT electric boilers	94 500 kW	203,23
Thermal units ТС1-075	32,131 kW	40,49
Liquid-fuel boilers "KChM-5" with Italian burner	40 320 л. diesel fuel	322,56

Benefits of use: The unit’s compact size, light weight, and easy assembly enable quick installation on a single platform in any location. It can also be connected straight to the current heating system.

Water treatment is not necessary.

There is no need for service staff to be present all the time when using an automated control system.

When installing heat plants directly at heat consumers, there are no heat losses in the heat pipelines.

Because there are no combustion products or other hazardous materials released into the atmosphere during operation, it can be used in locations with lax MPE regulations.

The payback period varies between six and eighteen months for the installation of heat plants.

Installing an electric motor with a supply voltage of 6000–10,000 volts can be done in the event that there is insufficient transformer power (only for 250 and 400 kW).

Advantages and disadvantages

A straightforward device that transforms fluid energy into heat energy is a cavitation water heater.

There are benefits to this technology:

• efficiency;
• fuel economy;
• availability.

You can purchase the components from a construction store and assemble the heat generator by hand.

The parameters of such a device will be the same as those of factory models.

The drawbacks consist of:

• increased noise level;
• The complexity of selecting the material for the working tank;
• For premises with an area of up to 80 square meters, the capacity of the device will be excessive;
• free space for installation of the device is required.

Crucial! Use specialized equipment that can slow down the flow of water to adjust the liquid’s velocity.

Economical cavitation heat generator with your own hands

If you closely examine the device’s drawings and schematics and comprehend its basic workings, it is quite possible to build a homemade vortex generator with cavitation. Potapov’s WTG, with an efficiency of 93%, is thought to be the most straightforward for independent creation. This system can be used for both domestic and commercial purposes.

It is vital to carefully choose the pump before moving on to the device’s assembly, paying attention to factors like the pump’s type, capacity, needed thermal energy, and head size.

It is generally accepted that the nozzle shape, which is the most straightforward and practical for these kinds of devices, is shared by all cavitation generators.

What is required in order to make a cavitator?

• Pressure gauges for measuring pressure;
• Thermometer for temperature measurement;
• Outlet and inlet spigots with taps;
• Valves for removing air locks from the heating system;
• Thermometer sleeves.

The cross-sectional size of the orifice connecting the diffuser and confuser must also be considered. It shouldn’t be any smaller or wider than 8 to 15 centimeters.

Design plan for generating cavitation:

1. Choosing a pump – here it is necessary to determine the required parameters. The pump must necessarily be able to work with liquids of high temperatures, otherwise it will quickly break down. It should also be able to create a working pressure of at least 4 atmospheres.
2. Creating a cavitation chamber – the main thing here is to choose the right size of the cross-section of the passage channel. 8-15 mm is considered optimal.
3. Choosing the nozzle configuration – It can be in the form of a cone, cylinder or simply be rounded. However, the shape is not as important as the fact that the vortexing process starts as soon as the water enters the nozzle.
4. Fabrication of the water circuit – This is a curved tube leading from the cavitation chamber. Two thermometer sleeves, two pressure gauges, an air valve which is placed between the inlet and outlet are connected to it.

You can paint the cavitation heat generator’s casing any color you choose.

The heat generator needs to be tested after the body is constructed. The pump and radiators need to be connected to the heating system and electricity, respectively, for this purpose. It is then linked to the network.

It is particularly important to pay attention to manometer readings and establish the desired 8–12 atmosphere range between the liquid’s inlet and outlet.

Water is then forced into the system. It’s good if it heats up by 3–5 degrees per minute in 10 minutes. The liquid will be heated to 60 degrees for a brief period of time. This is more than enough for the task.

Making a heat generator with your own hands

A list of parts and fixtures for creating a heat generator:

• two pressure gauges are needed to measure the pressure at the inlet and outlet of the working chamber;
• A thermometer to measure the temperature of the inlet and outlet liquid;
• valve to remove air plugs from the heating system;
• inlet and outlet connections with faucets;
• thermometer sleeves.

Selection of a circulating pump

Determining the device’s necessary parameters is necessary for this purpose. The pump’s capacity to handle liquids at high temperatures is its primary feature. If this issue is not addressed, the pump will break down soon.

Next, the working pressure that the pump is capable of producing must be selected.

To increase the liquid’s heating rate, you can increase the reported pressure of 4 atmospheres at the liquid’s inlet up to 12 atmospheres using a heat generator.

Since the liquid passes through a conditionally narrow nozzle diameter during operation, the pump’s performance won’t significantly affect the rate of heating. typically moves three to five cubic meters of water every hour. The heat generator’s operation will be significantly impacted by the coefficient of conversion of electricity to thermal energy.

Manufacturing of the cavitation chamber

A prime example is the functionality of a Laval nozzle device, which is updated by a craftsman who creates a generator by hand.

The choice of the passage channel’s cross-sectional size requires careful consideration. It ought to optimize the liquid’s pressure drop.

The cavitation process will be more vigorous and the water will shoot out of the nozzle under greater pressure if you arrange it with the smallest diameter.

However, in this instance, there will be less water flowing, which will cause it to mix with colder masses. A tiny nozzle opening also contributes to the formation of more air bubbles, which raises the noise level during operation and may cause bubbles to start forming inside the pump chamber. This will shorten its lifespan. Practice has shown that a diameter of 9 to 16 mm is deemed to be the most acceptable.

Nozzles can be rounded, cone-shaped, or cylindrical in shape and profile. It is impossible to state with certainty which option will be more successful because it all depends on the installation’s other factors. The crucial point is that the vortex process starts as soon as the liquid enters the nozzle for the first time.

Making a water circuit

Prior to using chalk, the circuit length and its peculiarities should be schematically drawn out and transferred to the floor. The circuit can be conceptualized as a curved tube that is fed back into the entrance after being connected to the cavitation chamber’s outlet. Two pressure gauges, two sleeves, and a thermometer are connected as additional devices. There is a valve in the circuit for collecting air as well.

Water enters the circuit in a counterclockwise direction. We installed a valve between the inlet and the outlet to control the pressure. It is customary to use pipe with a diameter of 50 to match the spigot sizes.

Older heat generator models operated without the need for nozzle installation; instead, the water in a long enough pipeline was accelerated to raise the water head. But, using excessively long pipes is not worthwhile in our situation.

Generator testing

The heating system is connected to the radiators, and the pump is powered by electricity. Testing can begin after the equipment is installed. The motor turns on when the mains are turned on. In this situation, it’s important to monitor pressure gauge readings and use a valve to adjust the required differential between the water inlet and outlet. The range of the atmosphere difference should be between 8 and 12 atmospheres.

The water is then turned on, and the temperature parameters are monitored. In ten minutes, the system will reach a suitable temperature of 3–5 degrees Celsius. The temperature quickly rises to 60ºC. Fifteen liters of water power both the pump and our system. This is more than enough for smooth operation.

Since all of the components are used in a ready-made form, all that is needed to apply heat generators in a home is a little bit of motivation and assembly expertise. Additionally, the effectiveness won’t make you wait.

Overview of popular models

Although the cavitation process has not yet been thoroughly investigated, experts at numerous businesses are already developing equipment based on its principles. Additionally, some models are currently being prepared for mass production. These are the electrical installations that are utilized for hot water preparation and heating.

Heat source from the TC1 brand

However, models have already been produced. We can use the TC1 cavitation heat generator as an illustration. This is a cutting-edge, multifunctional gadget that operates with great efficiency. It can be applied to systems for hot water preparation, ventilation, and heating.

A standard 3000 rpm motor running on a 380 V mains supply powers the device. It is mounted on the same frame as the thermal energy-converting activator, which transforms mechanical energy.

A few of the CIS nations produce cavitation heat generators. Additionally, various manufacturers go by different names.

In the former Soviet Union, the most well-known businesses are as follows:

• YUSMAR (Moldova);
• YurLe and Co (Belarus);
• Tekmash (Ukraine);
• Graviton (Russia).

Their costs are excessive since it is still very difficult to purchase such a device. For instance, the average cost of a domestic cavitation heat generator with a 50 kW capacity is between 50 and 55 thousand rubles.

When it comes to design, vortex models are more straightforward, but their effectiveness is a little bit lower. These days, very few companies sell products of this class on the market. One of them is the NPP New Technologies-manufactured Radex brand rotary hydro-impact pump.

The Belarusian company Yurle-K manufactures the hydro-impact and electro-hydro-impact models Tornado and Vektorplus respectively. In the CIS countries, dealer centers and retail stores sell them.

Some factories in Russia produce similar equipment. Most of the units in their line are low-power models. VTG – 2,2 is the smallest of them all. A building with a maximum volume of 90 m³ can be heated by it. It operates on the same principle as other devices of a similar nature. The heat generator’s rotor has a screw installed on it that allows liquid to flow through. It is fed into the heating pipeline after being heated. This model costs no more than thirty-four thousand rubles.

The VTG-30 cavitation heat generators are classified as medium power indicators. This model is intended for homes up to 1400 square meters in volume. It must, however, be purchased with a control cabinet in a set. In this instance, the liquid’s heating will be entirely automated. However, the price of such a gadget is roughly 150,000 rubles.

Take a brief look at the vortex heat generator video:

ITPO cavitation vortex heat generators are made in Izhevsk. They have a cylindrical nozzle and a motor attached. Pressurizing the liquid, the unit operates in pump mode. Next, a vortex flow is produced that can be broken up with a braking mechanism. Here’s where the heating medium gets heated.

The efficiency of this model is said by the manufacturer to be up to 150%. Maybe this signal draws in a sizable number of buyers who are interested in purchasing cavitation heat generators to heat their own houses.

A little history

The vortex heat generator is regarded as an inventive and promising invention. However, the technology is not new; scientists were considering applications for the phenomenon of cavitation nearly a century ago.

This phenomenon, which was discovered at the beginning of the 20th century and is still used in practice today, is a wound pipe that penetrates a gaseous medium and splits into hot and cold air.

French engineer Joseph Ranck created and patented the "vortex tube," the first operational pilot plant, in 1934.

It was observed by Rank initially that there is a difference in temperature between the air at the cyclone’s (air cleaner) inlet and outlet. Nevertheless, during the preliminary bench tests, the vortex tube’s ability to cool the air jet was evaluated rather than its ability to heat it.

The vortex tube’s basic working principle is as follows: after passing through the swirl chamber, the flow splits into two streams with distinct temperatures.

In the 1960s, a new advancement in technology occurred when Soviet scientists discovered that launching liquid into the Ranck’s pipe instead of air stream would improve it.

The liquid’s temperature changed more intensely as it passed through the vortex tube because the liquid medium had a higher density than air. Consequently, it was discovered through experimentation that the liquid medium traveling through the upgraded Rank pipe heated up unusually fast and had a 100% energy conversion factor!

Regrettably, the technology was not put to use because there was no demand for inexpensive thermal energy sources at the time. In the mid-1900s of the 20th century, the first cavitation units with an operating mechanism for heating liquid medium were developed.

The image displays a demonstration vortex generator with a closed-loop water circulation system.

Resuming work on effective energy converters of water jet motion into heat was motivated by a series of energy crises and the resulting growing interest in alternative energy sources. Because of this, most heating systems can now be used with a unit of the necessary power that can be purchased.

Types of heat generators

Rotary heat generator

One such gadget is an altered centrifugal pump. The pump casing, which houses the inlet and outlet pipe, functions as the stator in this kind of apparatus. The primary mechanism consists of a chamber that houses a rotor that can be moved and functions similarly to a wheel.

The rotor design has changed significantly since cavitation pumps were first developed, but the rotor itself has remained constant. The Griggs model, which was among the first to successfully create a cavitation-acting heat generator, is regarded as the most productive. The rotor of such a device is constructed like a disk with many holes punched into its surface. They have a specific diameter and depth and are blind. The frequency of the electric current and, thus, the rotor’s rotation determine the number of cells.

A heat generator’s stator is a cylinder with sealed ends around which the rotor revolves. There is roughly 1.5 mm of space between the stator walls and the rotor disk.

The formation of cavitation cavities in the liquid jet’s thickness, which continuously rubs against the stationary and movable cylinder surfaces, requires rotor cells. The fluid heats up in the same gap. The transverse size of the rotor, which is dictated by its 3000 revolutions per minute rotation speed, must be at least 30 centimeters for the heat generator to operate efficiently. The number of revolutions should be increased if the rotor has a smaller diameter.

The balancing of the moving cylinder is one of the components of the rotary heat generator that requires precise operation despite its seeming simplicity. It is necessary to seal the rotor shaft and replace any failed insulation materials permanently.

Such generators work with a noise effect and have an unimpressive coefficient of efficiency. Despite operating 25% more efficiently than static heat generator models, they have a short service life.

Static generator pump

The equipment’s name for the static heat generator was received under condition because it lacks rotating action parts. A nozzle design is used to induce cavitation processes in the liquid.

High water velocity is necessary to recreate the cavitation phenomenon, and a strong centrifugal pump is used to achieve this. The water flow is accelerated by the pump and pours into the nozzle inlet port. The nozzle’s outlet diameter is significantly smaller than its predecessor’s, giving the liquid more motion energy and increasing its speed. Due to the water’s quick expansion at the nozzle outlet, gas cavities inside the liquid body form, causing cavitation effects. Water is heated using the same principle as in the rotary model; the efficiency is just slightly lower.

Static heat generators are superior to rotating models in a number of ways.

• The design of the stator device does not require fundamentally accurate balancing and fitting of parts;
• mechanical preparatory operation does not require clear grinding;
• due to the absence of moving parts, there is much less wear on the sealing materials;
• the operation of the equipment is longer, up to 5 years;
• in case of nozzle failure, its replacement will require less expenses than in the rotary version of the heat generator, which has to be recreated anew.

Idea of creation

If you don’t have enough cash to purchase a heat generator, what should you do? How can I make it on my own? In this instance, I will share with you my personal experience.

Having become familiar with various kinds of heat generators, we had the notion to construct our own. Their designs appeared fairly straightforward but ill-considered.

There are two known designs for these devices: static and rotary. As the name suggests, the rotor is utilized to produce cavitation in the first instance, whereas the nozzle serves as the primary component of the apparatus in the second. Let’s compare the two designs so that you can decide which one is better.

Cavitation

At first glance, the topic of cavitation heat generators seems fantastic and is crossed out of Wikipedia, but on detailed study it turned out to be curious. The more interesting the question became the further the authors delved into the study. Fominski"s book on free energy sources begins by describing the global ecological catastrophe of the late 20th century. Among the well-known facts about the harm of internal combustion engines, incredible information about the value of cavitation heat generators are hypotheses about changing the breathing mode of the planet"s forests and… about stopping the warm Gulf Stream current. In 2003, the book read like a science fiction book. Recall, now Europe is concerned about the stopping of the Gulf Stream, it becomes clear that the author was able to predict the future for 10 years in advance.

This suggests that the concept of cavitation heat generators may not be as futuristic as the media would have us believe. Although the efficiency of thermoelectric sources was known to be negligible at the start of the 20th century, this direction is now thought to be promising. The early thermocouples had an efficiency of up to 3%, which is on par with the early 19th-century success of steam engines. According to engineers (see. screen), a cavitation heat generator’s efficiency can already exceed unity.

Pump for cavitation heat generation. Simply put, the fluid flow moves energy from one location to another. Every refrigerator and air conditioner with efficiency levels above 100% operates on the same principles as a heat pump, moving energy from one area of a room to another. Think of it like watering a tree: the roots cannot be nourished by electrical energy, but if you connect a propeller to the engine, water flows out to provide vital moisture. The cavitation heat generator operates on the exact same principle.

A heat pump is regarded as an expensive piece of machinery. usually drawing heat from a river stream or the interior of the Earth. Because these sources have low temperatures, it is possible to achieve heat intake and delivery to the desired location by lowering the Freon pressure. Frost is not produced by the refrigerator directly. Freon is released, and as a result of the laws of thermodynamics, heat is transferred to the evaporator and then to the radiator located on the back wall.

Similar to this, cavitation bubbles form in locations where the water pressure drops below the point at which one aggregate state changes (see fig. Consequently, a significant quantity of energy is taken in. To change the substance into a different aggregate state, heat must be applied. which is drawn from the nearby water and pumped out of the room and the cavitation heat generator body. The pump pressurization causes heat to be produced on the body. The reason for efficiency above unity is environmental heat extraction. high percentage of the generator’s internal winding heating and friction losses being used.

Static heat generator

Conventionally, the second kind of heat generator is referred to as static. This is because the cavitator design does not include any rotating components. Several nozzle kinds are employed to produce cavitation processes. The so-called Laval nozzle is the most often utilized.

In order for cavitation to occur, a high velocity of the liquid in the cavitator must be ensured. A conventional centrifugal pump is used for this purpose. The pump pressurizes the fluid upstream of the nozzle, it rushes into the nozzle orifice, which has a much smaller cross-section than the supply pipe, which provides a high velocity at the nozzle outlet. Due to the sudden expansion of the liquid at the nozzle outlet, cavitation occurs. It is also favored by the friction of the liquid on the surface of the nozzle channel and water swirls, which arise when the jet is abruptly torn out of the nozzle. That is, the water is heated for the same reasons as in a rotary heat generator, but with somewhat lower efficiency.

A static heat generator’s design does not call for extremely precise part manufacturing. Compared to the rotary design, these parts are manufactured with minimal mechanical processing. The problem of sealing of mating assemblies and parts can be readily resolved because there are no rotating parts. Furthermore, balancing is not required. The cavitator’s service life is significantly longer. (5-year guarantee) The cost of manufacturing and replacing the nozzle will be much lower even if it has reached the end of its useful life (a rotary heat generator in such a scenario would have to be essentially re-manufactured).

The price of the pump is possibly the biggest drawback of the static heat generator. Nevertheless, the cost of producing a heat generator with this design is essentially the same as that of the rotary version. Additionally, if we take into account the resources used in both installations, this drawback becomes a benefit since the pump need not be changed when the cavitator pump needs to be replaced.

We will therefore choose a static heat generator, especially since we already own a pump and won’t need to pay for one.

How to assemble the heat generator

Workplace instruments

It is quite feasible to make HTG at home even with all these technical terms, which could intimidate someone who is not familiar with physics. Of course, it will require some work, but you can always enjoy the heat if everything is done correctly and well.

As with any other business, you will need to set up supplies and equipment before you can start. What you’ll need is

• Welding machine.
• Grinder.
• Electric drill.
• Set of wrenches.
• Set of drills.
• Metal angle.
• Bolts and nuts.
• Thick metal pipe.
• Two threaded sockets.
• Connecting sleeves.
• electric motor.
• Centrifugal pump.
• Nozzle.

You can now go straight to work.

Installing the motor

An electric motor made of angle steel that is bolt-assembled or welded and mounted on a bed, depending on the voltage available. The bed’s overall dimensions are determined so that the pump and motor can fit inside of them. To prevent rusting, it is preferable to paint the frame. Drill the holes, mark them, and put the electric motor in.

Connect the pump

Two factors should be considered when choosing a pump. Primarily, it needs to be centrifugal. Second, the motor’s power needs to be adequate to spin it up. Following the installation of the pump on the bed, the following is the sequence of events:

• In a thick pipe with a diameter of 100 mm and a length of 600 mm on both sides you need to make an external groove of 25 mm and half the thickness of the pipe. Cut the thread.
• On two pieces of the same pipe, each 50 mm long, cut the internal thread on half the length.
• Weld metal covers of sufficient thickness on the side opposite to the thread.
• Make holes in the center of the lids. One according to the size of the nozzle, the other according to the size of the spigot. On the inside of the nozzle hole with a large-diameter drill bit, chamfer the hole to create a nozzle-like shape.
• The nozzle pipe is connected to the pump. To the hole from which water is supplied under pressure.
• The input of the heating system is connected to the second branch pipe.
• The output from the heating system is connected to the pump inlet.

The cycle has ended. As a result of cavitation and the vortex that forms inside the nozzle, water will be forced through it and heated. Installing a ball valve behind the pipe that allows water to return to the heating system will allow for temperature regulation.

To increase the temperature, slightly close it; to decrease it, open it.

Let"s improve the heat generator

Strange as it may seem, but even this intricate design has room for improvement to boost performance even more. This will be beneficial for heating a large private home. The reason for this improvement stems from the pump’s inherent tendency to lose heat. Therefore, you need to get it to use the least amount of it.

There are two methods to accomplish this. Use any appropriate thermal insulation material to insulate the pump. Or put a water jacket around it. Without any further explanation, the first option is obvious and easy to use. However, a more thorough discussion of the second one is necessary.

The pump will need to be housed in a specifically made, hermetically sealed container that can withstand the pressure of the entire system in order to construct a water jacket for it. This container will receive the water, which the pump will then take from there. Additionally, the heated external water will enable the pump to function much more efficiently.

Vortex absorber

However, as it happens, that’s not all. The vortex heat generator can be fitted with a vortex damper after it has been thoroughly examined and comprehended. The stream of pressurized water hits the wall across from it and swirls. However, more than one vortex may exist. All that needs to be done is incorporate a structure within the device that resembles the shank of an airplane bomb. The following is how this is carried out:

• From a pipe of slightly smaller diameter than the generator itself you need to cut two rings with a width of 4-6 cm.
• Inside the rings, weld six metal plates, selected in such a way that the entire structure turned out to be long equal to a quarter of the length of the body of the generator itself.
• When assembling the device, fix this construction inside opposite the nozzle.

Perfection knows no bounds and cannot be contained, and the vortex heat generator is still being enhanced today. Not every person is capable of doing that. However, assembling the device in accordance with the above-mentioned scheme is quite feasible.

Design features of the equipment

Such a unit—what is it? Its primary component is a cavitation heat generator, which is constructed like a pump and has a unique flow profile. As the water flows through it, it gets heated. This is the result of a vortex flow forming. Cavitation discontinuities cause the liquid to heat up when they occur in it. Furthermore, any antifreeze can serve as a coolant.

View the video and the generator’s device:

The liquid’s chemical composition changes as a result of heating because the liquid’s pressure drops dramatically. This process produces inexpensive energy that can be used for heating.

Generally speaking, these installations use 1.5 times less energy than radiators and other types of systems. In this instance, as the liquid moves through the cavitator, it heats up in a closed circuit.

Such devices work on the principle of converting one form of energy into another. It is then transformed into heat, with a notable difference between the amount released and used.

One of the benefits of cavitation heat generators is that they can be installed without the need for any paperwork. This is because the electric motor in them is the only appliance that runs on electricity.

Despite the fact that currently none of the theories can adequately explain the processes taking place in the cavitator, they are still in use and working fairly well throughout the world. The focus of scientific research in this field is limited to resolving the operational quirks of thermal installations of this kind.

In this comprehensive guide, we delve into the intricacies of crafting vortex heat generators from scratch, providing enthusiasts with a step-by-step manual to construct their own efficient heating systems. From understanding the principles behind vortex technology to sourcing materials and assembling the components, this article offers a hands-on approach to mastering the art of DIY heat generation. With detailed instructions and practical tips, readers will learn how to harness the power of swirling air to produce sustainable and cost-effective heat for their homes. Whether you"re a seasoned DIY enthusiast or a novice in the realm of home improvement, this guide equips you with the knowledge and skills needed to embark on your own vortex heat generator project, revolutionizing the way you heat and insulate your living space.

Buy or build

As you can see, heat generators are extremely expensive. Since not everyone can afford one, economists attempt to create one on their own. Buying or doing it yourself directly depends on a person’s skills and abilities as well as the family’s wealth. Given the device’s relatively complex design, it is best to avoid taking a chance and to avoid wasting time in vain if there isn’t one.

As a result, the cavitation heat generator is a great choice for a backup home heating source. However, the majority of people on the planet cannot afford it due to its high cost.

It is also possible to assemble it by hand, but this option is only warranted in cases where you possess specialized knowledge.

Two basic types

Even though there are occasionally reports that someone has created a special vortex heat generator with so much power that it can heat an entire city, these are typically just newspaper rumors with no supporting evidence. Perhaps one day, but for now, there are only two ways in which this device can be used in terms of its principle of operation.

Generator of rotary heat. In this instance, the centrifugal pump’s casing will serve as a stator. The entire surface of the rotor is drilled with holes of a specific diameter, depending on the power. The bubbles themselves are what cause the water to heat up when they burst. Such a heat generator has only one benefit. It produces far more. However, the drawbacks are far more severe.

• Such a unit is very noisy.
• Wear and tear of parts is high.
• Requires frequent replacement of seals and glands.
• Too expensive to maintain.

Generator of static heat. This version differs from the previous in that there is no rotation and the cavitation process happens organically. The pump is the only one that functions. Additionally, the list of benefits and drawbacks goes in the exact opposite direction.

• The device can operate at low pressure.
• The temperature difference between the cold and hot ends is quite large.
• Absolutely safe, wherever it is used.
• Fast heating.
• The efficiency is 90% or more.
• It can be used both for heating and cooling.

The hefty equipment cost and correspondingly lengthy payback period are the sole drawbacks of the static WTG.

The main thing is the motor

The voltage available should be taken into consideration when choosing a motor. A 380 volt motor can be connected to a 220 volt network using a variety of schemes, and vice versa. But that’s a different subject.

Start the heat generator assembly by attaching the electric motor. It needs to be secured to the bed. This device is designed with a metal frame, which is most easily made out of angle bar. For the devices that will be available, dimensions must be chosen on the spot.

Illustration of a heat-generating vortex.

List of equipment and supplies:

• angle grinder;
• welding machine;
• electric drill;
• drill set;
• 12 in. and 13 in. horn or socket wrenches;
• bolts, nuts, washers;
• metal angle;
• primer, paint, paint brush.

1. Cut the angles with the help of an angle grinder. Using a welding machine, assemble a rectangular structure. As an option – you can assemble using bolts and nuts. The final design will not be affected. Adjust the length and width so that all parts are optimally placed.
2. Cut out another piece of angle iron. Attach it as a crossbeam so that the engine can be attached.
3. Paint the frame.
4. Drill holes in the frame for bolts and install the motor.

Equipment and principle of operation

The device in the most basic construction consists of the following components:

1. Rotor, made of carbon steel;
2. Stator (welded or monolithic);
3. A clamping sleeve with an inner diameter of 28 mm;
4. A steel ring.

Let’s examine the generator’s operating principle using the cavitation model as an example. Water enters the cavitator within it, whereupon the motor spins it. The unit’s operation causes the coolant’s air bubbles to collapse. Here, the liquid that is trapped in the cavitator warms up.

In order for the device to function, which must be assembled by hand using the network drawings provided, keep in mind that energy is needed to overcome the device’s friction force, create vibrations in the sound, and heat the liquid. Furthermore, the device’s efficiency is nearly 100%.

Test of the heat generator

You can move on to the tests once the installation is connected. After turning on the electric pump motor, we determine the required pressure drop by monitoring the pressure gauge readings. A valve is located in the circuit between the inlet and outlet nozzles specifically for this purpose. Adjust the pressure in the pipeline after the nozzle to between 1.2 and 1.5 atm by turning the valve handle. The ideal pressure in the circuit section between the pump outlet and the nozzle inlet is 8–12 atm.

We were able to obtain a pressure of 9.3 atm at the nozzle inlet from the pump. We let the water run in a circle (closed the outlet valve) after setting the pressure at the nozzle outlet to 1.2 atm and noted the time. We observed a temperature increase of roughly 4°C per minute as the water traveled along the circuit. As a result, we have already heated the water from 21°C to 60°C in 10 minutes. With the installed pump, the circuit’s volume was close to 15 liters. The calculation of electricity consumption involved the measurement of current. We can determine the energy conversion factor using these data.

KPI = 3600000*(Qk-Qn) / (C*m*(Tk-Tn));

• C – specific heat capacity of water, 4200 J/(kg*K);
• m – mass of heated water, kg;
• Tn – initial water temperature, 294° K;
• Tk – final water temperature, 333° K;
• Qn – initial reading of the electric meter, 0 kWh;
• Qk – readings of the electric meter final, 0.5 kWh.

Now let’s enter the data into the formula to obtain:

KPE = (3600000*(0,5-0))/(4200*15*(333-294)) = 1,365

This indicates that our heat generator generates 1.365 times more heat, or 6.825 kWh, for every 5 kWh of electricity used. We can therefore confidently state that this theory is true. The real transformation ratio will be even higher because this formula does not account for the motor’s efficiency.

When calculating the thermal power required to heat our house, we proceed from the generally accepted simplified formula. According to this formula for a standard ceiling height (up to 3 m), our region requires 1 kW of heat capacity for every 10 m2.Thus, for our house with the area of 10×10=100 m2 we will need 10 kW of heat capacity. Т.е. A single 5.5 kW heat generator is not enough to heat this house, but this is only at first glance. In case you haven"t forgotten, we are going to use a floor heating system to heat the room, which saves up to 30% of the energy consumed. It follows that the 6.8 kW of heat generated by the heat generator should be sufficient to heat the house. In addition, the subsequent connection of the heat pump and solar collector will allow us to further reduce energy costs.

Magnet generator

Vortex-type magnetic heating systems operate similarly to induction heaters. An electromagnetic field is created during operation, and the heated objects absorb this field’s energy and transform it into thermal energy. An induction coil, a multithreaded cylindrical coil that generates an alternating state magnetic field when an electric current passes through it, is the central component of such a device.

Using their hands, they can create a magnetic heat generator out of taps, induction elements, thermometers with sleeves, nozzles, and pressure gauges at the outlet. The magnetic induction flux produced by such a unit will penetrate the object that needs to be heated if it is placed close to it. The lines of the electric field form a closed circle and are positioned perpendicular to the direction of the magnetic particles. The object heats up as a result of the electricity’s eddy currents diverging and transforming into thermal energy.

Using an inverter and your own hands, you can create a magnetic heat generator that rapidly reaches high temperatures by using the power of magnetic fields to start the pump and heat any materials in the room. These heaters have the ability to melt metal in addition to heating water to the proper temperature.

Physical basis

Cavitation is the process by which vapor forms in a mass of water at a high velocity of movement and a gradual drop in pressure.

A coherent light source or a sound wave at a specific frequency can both produce vapor bubbles.

The process of combining pressurized water with vapor voids causes bubbles to spontaneously collapse and shock force to emerge in the water (this article discusses how hydraulic shock is calculated in pipelines).

When these circumstances are met, molecules of dissolved gas are released into the cavities that result.

The temperature inside the bubbles rises to 1200 degrees Celsius as the cavitation process continues.

Water containers are negatively impacted by this since the intense oxidation of the material by oxygen occurs at these temperatures.

It has been demonstrated through experiments that even alloys containing precious metals can be destroyed in such circumstances.

It’s very easy to make your own cavitation generator. For a number of years, the thoroughly researched technology has already been incorporated into materials and utilized for space heating.

The first gadget was patented in Russia in 2013.

The generator was a sealed apparatus that generated pressure in water. The action of an alternating electromagnetic field causes vapor bubbles to form.

Advantages and disadvantages of self-made heat generators

There are benefits and drawbacks to cavitators. The latter are more so far. Science is currently attempting to at least level the score, if not tilt the device in a positive direction.

Krasnov’s cavitator design shows a lot of promise. In accordance with his theory, a liter of water can be heated by adding a few drops of spent oil. As a result, there are cavitation bubbles and a perfect burn in the water.

Therefore, we advise you to start by thinking about the benefits of cavitators. Though they are few in number, they seem promising.

Benefits of heat generators with cavitators:

• Energy is indeed generated by cavitation;
• This device is very economical as it requires practically no fuel;
• Inexpensive to make with your own hands.

These are most likely the only benefits of this gadget thus far. It does, however, also have drawbacks.
