Patent ID: 7040303

Claim:
A cooling system for an internal combustion engine having a supercharger for increasing the density of intake air supplied to the engine, the cooling system comprising: a liquid cooling subsystem including at least one liquid cooling loop having a pump communicating with a radiator and the engine for unidirectional circulation of liquid coolant; an intake air cooling subsystem including an air-to-water aftercooler having an intake air side receiving intake air from the supercharger and a water side receiving liquid coolant from the liquid cooling subsystem, and an air-to-air aftercooler having an intake air side receiving intake air from the air-to-water aftercooler; a shared fan circulating air flow through cooling air sides of the air-to-air aftercooler and the radiator; an air distribution control operative to control the amount of circulated air flow directed from the shared fan to the cooling air sides of the radiator and the air-to-air aftercooler; the air-to-water aftercooler being operative to exchange heat between the intake air and liquid coolant; and the air-to-air aftercooler being operative to exchange heat between the intake air and circulated air.
