MULTI-CONTOUR CAVITATION THERMO-GENERATOR Russian patent published in 2007 - IPC F24J3/00 

FIELD: engineering of devices for producing heat, which is created due to friction of liquid against walls of channels and surfaces of device, relatively to which aforementioned liquid flows, and also due to creation and following destruction of cavitation bubbles; thermo-generator may be used in water heating systems, hot water supply systems and for other purposes when heated liquid is required.

SUBSTANCE: thermo-generator contains cyclone with inlet and outlet apertures, outlet nozzle, barrel-shaped body, wall of which is formed by coils of pipe, tightly wound in form of extension spring with rigid connection of adjacent coils to each other with inlet and outlet branch pipes on supporting coils, while nozzle and body are each connected by its open hollow, rigidly and hermetically, to one of appropriate opposite sides of cyclones coaxially to each other, braking element, tank with liquid substance (heat carrier), in which thermo-generator is immersed, with outlet aperture of cyclone oriented tangentially and directionally, appropriately to angle of inclination of pipe coils into body chamber. In bottom section of body along its axis a through aperture is made, while braking element is made in form of circular end shelf on a part of output nozzle connected to cyclone, and formed due to difference of diameters of body chamber and outlet aperture of nozzle, and also a cover belonging to hydrophobic polymer group is applied to internal surfaces of thermo-generator in contact with liquid substance streams.

EFFECT: increased intensiveness of cavitation process, which is the main factor for increasing heat yield of thermo-generator; localization and separation of cavitation zone from structural elements leading to reduced harmful influence (erosion) on structural elements of thermo-generator while maintaining high liquid stream movement speed without substantial loss of simplicity caused to structure of thermo-generator.
