CAVITATION-TYPE ROTARY HEAT-GENERATOR Russian patent published in 2005 - IPC

FIELD: heat production by means other than fuel combustion for premises water heating systems.

SUBSTANCE: proposed cavitation-type rotary heat-generator has housing provided with heated-liquid inlet and outlet and cylindrical surface carrying two coaxial rings of which one is fixed in position relative to housing and other ring is set in rotary motion by drive shaft disposed coaxially with rings. The latter are provided with radial holes disposed in plane perpendicular to axis of revolution. External coaxial ring is revolving and internal one is fixed in position relative to housing, clearance of 0.5 to 3 mm being provided between external revolving ring and internal cylindrical surface of housing. Steel disk is turned onto threaded end of drive shaft and external revolving ring is turned onto its rim. Drive shaft has spider with steel spokes tightened by means of claw nuts installed in depressions of external revolving ring. Threaded end of drive shaft mounts metal head with rimmed textolite disk attached thereto; this rimmed disk carries external revolving ring. Diameter of holes in internal fixed ring is larger by 1.5 - 3 times that that of holes in external revolving ring. Hole number in external revolving ring is other than that in internal fixed one.

EFFECT: augmented cavitation processes occurring during rotor revolution which enhances heating efficiency.
