HEAT GENERATING PUMP Russian patent published in 2000 - IPC

FIELD: constructions of heat generating pumps suitable for using in autonomous closed systems for heat supply and for heating liquid in manufacturing equipment without burning organic fuel. SUBSTANCE: rotor pump-heat generator includes hollow housing with suction branch pipe for supplying heated liquid and pumping branch pipe for discharging heated liquid. Rotor in the form of centrifugal wheel with peripheral openings and stator with openings are arranged inside housing. Stator is mounted coaxially with rotor. Centrifugal wheel is double-flow one. Openings of rotor are in the form of conical nozzles narrowed towards stator side. Openings of stator are in the form of sharply widened nozzles with transition to cone flare nozzle with flare angle α=90 degrees. Such openings allow to eliminate effect of sticking boundary layer of liquid to wall and to increase zones of hydrodynamic cavitation. EFFECT: simplified design, intensified liquid heating due to increased effort of hydraulic shock and hydrodynamic cavitation. 4 dwg
