Patent ID: 7004245

Claim:
A system for aiding in prevention of engine overheating in a vehicle, wherein liquid coolant is circulated between the engine where it picks up heat and a radiator where it surrenders its heat as it flows through the radiator with a portion of the liquid coolant routed to a heater core where it further surrenders heat, which includes: an air duct system operably disposed in the vehicle having a fresh air inlet for receiving fresh air, first outlet means for exhausting air outside the vehicle, and second outlet means for exhausting air inside a passenger compartment of the vehicle; a cool air conditioning device operably disposed in said duct system to cool air as it passes thereby when in an “on mode”; a heater core operably disposed in relation to said duct system to continuously provide heat to said duct system and to heat air as it passes through said duct system and remove heat from said engine; first diverter means operably disposed in said duct system for continuously diverting at least some of said heated air toward said first outlet means when said cool air conditioning device is in an “on mode”; and second diverter means operably disposed in said duct system for continuously diverting at least one of fresh air and cool air toward one of said outlet means.
