VORTEX HEAT-GENERATOR Russian patent published in 2006 - IPC F24J3/00 

FIELD: heating engineering, particularly heating devices adapted for liquid heating by vortex and cavitational processes initiation in liquid used in different-purpose hydraulic systems.

SUBSTANCE: vortex generator comprises enclosed impeller made as centrifugal pump runner and has outlet closed with rim. The rim forms high-pressure zone at impeller periphery. The high-pressure zone is provided with working throttling orifices located from impeller ends. The throttling orifices are made as profiled slots, holes or slots and adapted for high-velocity liquid discharge in tangential direction at a given angle to angular velocity vector into toroidal vortex chambers located from impeller ends. The toroidal vortex chambers are communicated with inlet impeller blade zone through additional throttling channels. Working heat-generator cavities are hydraulically communicated with outer heat extraction system through outlet annular channel arranged around impeller rim and outlet channel coaxial to central inlet impeller orifice. The toroidal vortex chambers are provided with additional high-frequency liquid exciting sources.

EFFECT: simplified structure, improved energy and weight-dimension characteristics, possibility to use production-run impellers, as well as parts and assemblies of typical centrifugal pumps.
