AUTOMOTIVE AUXILIARY HEATER Russian patent published in 2011 - IPC B60H1/03 F24H1/00 

FIELD: transport.

SUBSTANCE: proposed heater communicates with the engine cooling system containing coolant, heat exchanger, and fluid heat generator with hydrodynamic chamber. Hydrodynamic chamber has inlet openings. Circulation and feed channel communicate heat exchanger and cooling system with inlet openings. In compliance with second version, proposed heater comprises expansion chamber and control valve with inlet communicated with heat exchanger outlet. Outlets are communicated with inlets of hydrodynamic chamber and cooling system. Heating system comprises engine, engine cooling system and heater wherein heat exchanger is communicated with generator. Fluid heater is coupled with engine crankshaft and comprises pulley attached to crankshaft, generator with casing attached to said pulley. In compliance with second version, proposed device comprises generator with inlet and discharge channels, and fluid tank. Fluid tank is communicated with generator inlet channel. Proportional valve has inlet communicated with generator discharge channel and outlet communicated with tank. Generator comprises rotor and stator, radial-flow compressor with inlet communicated with tank and outlet communicated with toroidal chamber. In compliance with third version, proposed device comprises reversible pump, channels to communicate the pump with tank and generator, and valve arranged in one of the channels. Valve serves to partially shut off fluid flow from generator into tank and rule out fluid flows in inoperative pump.

EFFECT: higher efficiency of heating system.
