AUTOMOBILE COOLING SYSTEM (VERSIONS) Russian patent published in 2006 - IPC B60K11/04 B60H1/00 

FIELD: automotive industry; automobile cooling systems.

SUBSTANCE: invention relates to cooling system of automobile which reduces fuel consumption and provides increase of traction power. Proposed cooling system of automobile contains inlet branch pipe 14 to receive ambient air and second heat exchangers 28,40 arranged near inlet branch pipe 14 and designed to take in first and second liquid coolants for cooling them with ambient air. First and second heat exchangers 28,40 are arranged close to each other without overlapping. Said heat exchangers 28,40 form first and second air ducts 52,54 passing in liquid flow in parallel through one of heat exchangers 28,40 from inlet branch pipe 14 to outlets 50,52,54. Fan 44 is designed to create air flow from inlet branch pipe though first and second ducts of flows. Louvers 56 in one of ducts 54 move between first and second positions limiting air flow and providing possibility of relatively unlimited flow of air. Drive is provided to shift louvers 56 from one position to the other. Drive control system generator signals to provide required conditions of operation of power transmission and air conditioning system.

EFFECT: reduced to minimum required power of fans with resulting possibility of use of smaller heat exchangers, as compared with those for standard cooling system of automobile of such type.
