摘要： A hybrid intercooler system is provided to adjust an oil temperature. The system includes an air cooling unit that exchanges heat with external air passing through outer surfaces of a plurality of compressed intake air channels and cools compressed intake air passing through interiors of the compressed intake air channels. A water cooling unit exchanges heat between engine cooling water enclosing the outer surfaces of the compressed intake air channels and the compressed intake air passing through the interiors of the compressed intake air channels and cools the compressed intake air. Additionally, an oil temperature controller exchanges heat between oil and the engine cooling water that is heated by the heat exchange performed by the water cooling unit and adjusts the temperature of the oil.
