ELECTRICALLY DRIVEN ROTATIONAL HEAT GENERATOR Russian patent published in 2007 - IPC F24J3/00 

FIELD: electrically driven heat generator with rotational working organs for heating residence rooms and separate buildings.

SUBSTANCE: heat generated at operation of electric motor is transmitted to outer heat consumption system due to forming heat exchange ducts along peripheral surface of stator of electric motor with supply duct communicated with heat consumption system. Heat exchange ducts are hydraulically insulated stator cavity filed with electrically insulating liquid and from rotor of electric motor. Arrangement of heat exchange ducts of electric motor between duct for supplying cooled heat transfer agent and inlet of energy-producing rotational working organs allows control pressure in cavity of shaft according to temperature of heat transfer agent in that cavity till level providing cavitation-free liquid flowing in said heat exchange ducts and in inner cavity of electric motor.

EFFECT: enhanced operational reliability, relatively small size and mass, improved vibration-acoustic characteristics of heat generator.
