ELECTRIC THERMOSTAT Russian patent published in 2006 - IPC F01P7/16 

FIELD: automotive industry; vehicle internal combustion engines.

SUBSTANCE: proposed thermostat contains solid filler, electric heater, housing with branch pipes to supply cooling liquid from engine and let it out to bypass into engine and radiator, two valves installed inside housing of rod, temperature and load sensors, comparator, control unit. Thermostat is installed in housing with possibility of heat exchange between solid filler and cooling liquid of cooling system and electric heater installed out of the cooling liquid whose input is connected to control unit, and output is connected with valves through filler, elongated rod and guide bushing. Thermostat can contain also built-in thermoelectric element installed out of cooling liquid whose input is connected to control unit, output is coupled with valves through filler, elongated rod and guide bushing, and junctions of thermoelectric element are connected through heat exchanger to cooling liquid end of cooling system. Moreover, electric thermostat inside housing can contain mechanical thermostat coupled with electric thermostat for parallel operation and switching off of electric thermostat at nominal loads.

EFFECT: possibility of maintaining optimum temperature conditions at partial loads within nonuniformity zone.
