Known heat and steam drive cavitation [Pat. No. 2362947 Russian Federation IPC F24J 3/00. Cavitation drive heat / steam generator / Vorobev S.A., Lavro N.M., Kornilov G.M., Shabanov D.V .; No. 2006141478/06; declared 11/24/2006; publ. 05/27/2008; Bull. No. 15], comprising a working body consisting of a casing, covers, working disks of a heat and steam generator, first and second impellers, dividing walls, two check valves, a third thermal valve, an expansion block for forming a steam-water mixture and a jet turbine. The steam generator disks with recesses in the form of spherical segments and guide channels deposited on the ends of the disks form three vortex spiral channels on each side of the disk, and guide channels are applied along the cylindrical surface of the disks at an angle of 15 degrees to their generatrix to direct the steam-water mixture along the axis of the steam generator in side of the second impeller.

The disadvantage of this device is its complexity in the implementation and in the use of two independent drives.

Known cavitation-vortex heat generator, [US Pat. No. 2235950 Russian Federation IPC F24J 3/00. Cavitation-vortex heat generator / Koshkin S.S., Atamanov V.V., Korotkov O.V., Markevich A.V .; applicant and patent holder: Limited Liability Company “NPK“ INATEK ”; No. 2002119773/06; declared 07/22/2002; publ. 03/27/2003; Bull. No. 25], comprising a housing having nozzles for supplying a heating fluid and removing heated fluid, a perforated stator and a rotor located inside the housing, a pressure pump, a rotor drive, where the stator and rotor are made in the form of disks perforated through holes. The stator is made in the form of one or several disks, and the rotor is made in the form of two disks mounted with a gap relative to each other, while the rotor disks are mounted on independent shafts having independent independent drives rotating towards each other.

The disadvantage of this device is the complexity of manufacturing technology, low maintainability, high hydraulic resistance, therefore, high power costs.

For the prototype adopted multifunctional vortex heat generator, [Pat No. 2527545 Russian Federation IPC F24J 3/00. Multifunctional vortex heat generator / Andropov A.E., Podyapolsky V.V., Trutnev V.V .; Applicants and patent holders: Andropov A.E., Podyapolsky V.V .; No. 20112150544/06; wilted. 11/26/2012; publ. 09/10/2014; Bull. No. 25], comprising a closed housing with nozzles for supplying a heated fluid and draining a heated fluid, rotors installed inside the housing, made in the form of two disks mounted on independent shafts having independent drives and having the ability to rotate towards each other. The heat generator contains suction turbines, which are rigidly fixed on independent shafts together with rotor disks, and in the rotor disks, opposite the installed turbines, through conical-cylindrical openings are made around the circumference, directed into the cavity between the disks, radially around the circumference of which rows of fingers are rigidly mounted . The fingers are made so that the rows of fingers of one disk freely enter with a gap between the rows of fingers of the second disk, and the conical-cylindrical holes of one disk are located opposite the conical-cylindrical holes of the other disk.

The disadvantage of the prototype is the large hydraulic resistance from the fingers located on the disks, which leads to an additional loss of power, as well as the complexity of manufacturing technology and the presence of an additional drive.

The technical result of the claimed invention is to reduce the hydraulic resistance while simplifying the design.

The specified technical result is achieved by the fact that in a heat generator comprising a closed housing with nozzles for supplying a heated fluid and removing heated, a rotor installed inside the housing, made in the form of disks mounted for rotation, according to the invention, the rotor disks are mounted on one shaft with an offset of circles with simultaneous displacement of cavitation cavities relative to each other, while the disks are connected together, and on their surfaces cavitation cavities are made parabol netocrystalline shape while rotating the parabola vertex located in the direction of drive.

The claimed technical result is achieved due to the fact that in the proposed disks bubbles appear on the surface of the cavities due to the rarefaction resulting from rotation. The shape of cavitation cavities provides lower hydraulic resistance compared to the prototype due to the claimed configuration of cavitation cavities, the vertices of the parabolas of which are located in the direction of rotation. Cavitation cavities of parabolic shape are stamped on the inventive disks, the disks being connected by smooth surfaces with a displacement around the circumference of the cavitation cavities relative to each other. The horizontal arrangement of the heat generator disks improves its operational characteristics. The proposed design of the heat generator ensures the manufacturability of its manufacture.

The proposed design of the heat generator is illustrated by the drawings which show: in FIG. 1 is a process diagram of a heat generator, FIG. 2 is a top view of a disk.

The heat generator comprises a housing 1, a rotor 2 in the form of disks 3, nozzles 4 for supplying a heated fluid and removing heated, a shaft 5 for driving cavitation disks 3, a bearing bearing assembly 6, cavitation cavities 7 of parabolic shape, the vertices of which are located in the direction of rotation of the disks 3, coupling 8, electric motor 9, speed control means 10.

The heat generator operates as follows. The heating fluid is sucked through the pipe 4, the rotating rotor 2 in the form of disks 3 with cavitation cavities 7 rotates in the direction of the vertices of the cavitation cavities 7 of a parabolic shape. In the cavitation cavities 7, a rarefaction occurs, which ensures the formation of bubbles, the collapse of which occurs on the surface of the disks 3. In this case, the liquid is thrown onto the wall of the housing 1, and then through the outlet pipe 4 for hot liquid enters the heating main. Powerful vortex flows are formed in the cavitation cavities 7 between the disks 3 and the housing 1, which enhances the cavitation process. As a result, a rarefaction region is formed inside the vortex, in which cavitation bubbles appear, and in the high-pressure region between the disks 3 and the housing 1, the microbubbles burst with the release of energy. The temperature control of the heated fluid is carried out by turning on / off the electric motor 9. When the coolant is cooled to the minimum set temperature, the electric motor 9 is turned off. Compared with the prototype, the proposed design of the heat generator is simple to manufacture and operate. The optimal modes are selected by means of controlling the speed 10. The dimensions of the cavitation cavities 7 are determined depending on the type and composition of the liquid. The diameter of the disk 3 is determined taking into account the necessary linear speeds.
