PURPOSE:To obtain a supercharged air cooler having little deterioration of a refrigerant and high cooling effect by cooling the cooling water for an inter- cooler cooling the supercharged air with the refrigerant of a refrigerator. CONSTITUTION:The air from an air cleaner 10 is fed into a combustion chamber 13 in with a supercharger 4 through an inter-cooler 14, a throttle valve 16, and an intake port 12. Cooling water is circulated by a pump 18 through an inter-cooler 14, the evaporator 19 of a refrigerator is arranged in a heat exchanger 20, the temperature of the intake air from the inter-cooler 14 is detected 28, the clutch 21 of a compressor 22 is engaged via the output of a control circuit 27, then a refrigerant flows into the evaporator 19 through a condenser 23, a refrigerant tank 24, a pipe 25, and a control valve 26 opened via the output of the control circuit 27, thus cooling the water and the intake air. Since the refrigerant is not brought into direct contact with the high- temperature intake air, it has little deterioration. |
