COOLING SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the cooling effect of an engine cooling system as well as to prevent overheating while keeping the size of the system from becoming larger. SOLUTION: In this cooling system, a heat exchanger 5 for cooling is placed within an air duct for an outer air 3 used for cooling which is generated by a fan 4 rotated by an engine 1, and an evaporator 21 for the freezing cycle is located on the windward side of the heat exchanger 5 for cooling. A condenser 22 for the freezing cycle is placed on the downwind side of the heat exchanger 5 for cooling. A compressor 23 for the freezing cycle is driven by the engine. The heat exchanger 5 for cooling is comprised of a radiator 6 which cools cooling water of the engine 1 and an oil cooler 8 which cools the hydraulic fluid of a pump 7.
