DEVICE AND METHOD FOR HEATING OF HEAT CARRIER CIRCULATING IN COOLING SYSTEM Russian patent published in 2014 - IPC F01P3/18 F01P7/16 F02B29/04 F02M25/07 F02N19/10 

Abstract RU 2518764 C1

FIELD: engines and pumps.

SUBSTANCE: proposed heater serves to heat heat-carrier in ICE cooling system (2) of vehicle (1). Cooling system comprises heat carrier cooler (18) arranged at vehicle point where through air flows at temperature (TA1, TA2) higher than ambient temperature, manifold with first line (16a) feeding heat carrier into engine (2) and second line (16b) feeding heat carrier into appropriate cooler (18). Besides it comprises valve (17) to be set to first position whereat it feeds heat carrier to ICE (2) and second position whereat it feeds heat carrier to appropriate cooler (18). Heater comprises control unit (22) to define if heat carrier in cooling system features temperature (TC) lower than working temperature (TD) if air in cooler (18) features temperatures (TA1, TA2) exceeding heat carrier temperature (TC). In case these conditions are satisfied, control unit (22) can drive valve (17) to second position so that heat carrier is fed to heat carrier cooler (18) whereat heat carrier is heated by air flowing through cooler (18). Invention covers also the heat carrier heating.

EFFECT: accelerated heating of heat carrier.
