CAVITATION-VORTEX HEAT GENERATOR Russian patent published in 2011 - IPC F24J3/00 

FIELD: heating.

SUBSTANCE: heat generator includes vortex chamber with two injection branch pipes located at an angle of 45-90° relative to each other and equally spaced throughout the chamber height, has curved shape of the bottom in the area of lower injection branch pipe, housing in the form of cylindrical pipe, bypass attaching the vortex chamber to the housing base. Brake device is installed in the housing base opposite to vortex chamber, as well as there is additional brake device in the bypass. Both brake devices includes ribs in each of which there is number of holes located parallel to axis of housing and axis of bypass. Besides, flow swirling devices representing cylindrical bushings with inner screw surface are installed at the inlet of injection branch pipes of vortex chamber, and housing is connected to vortex chamber by means of branch pipe having curved profile.

EFFECT: increasing liquid heating efficiency owing to increasing the intensification of formation process of cavitation caverns.
