PROBLEM TO BE SOLVED: To inexpensively configure a cooling system that can suppress overheat of an internal combustion engine even if a valve for controlling a cooling medium breaks down.SOLUTION: In the cooling system, a first flow passage L1 for supplying the cooling medium of the internal combustion engine E to a radiator 1 and a second flow passage L2 branching from the first flow passage L1 by a flow control valve V1 to supply the cooling medium to a first heat exchange part 3 are formed. The cooling system includes a third flow passage provided independently from the first flow passage L1 to supply the cooling medium to a second heat exchange part 4 via an on-off valve V2. The cooling system includes a control device 10 for controlling the on-off valve V2 and the flow control valve V1 based on the temperature of the cooling medium.
【課題】冷媒を制御する弁の故障時にも内燃機関のオーバーヒートを抑制できる冷却システムを低廉に構成する。【解決手段】内燃機関Eの冷媒をラジエータ1に供給する第1流路L1と、この第1流路L1から流量制御弁V1により分岐して第1熱交換部3に冷媒を供給する第2流路L2とを形成した。また、第1流路L1とは独立に設けられ開閉弁V2を介して第2熱交換部4に冷媒を供給する第3流路を備えた。冷媒の温度に基づいて開閉弁V2及び流量制御弁V1を制御する制御装置10を備えている。【選択図】図1
