PROBLEM TO BE SOLVED: To improve warming up of an internal combustion engine, in a cooling system that cools the internal combustion engine, and an electrical component accompanied by heat generation in operation.SOLUTION: The system is equipped with: a heat exchanger 3 which radiates heat by heat exchange with coolant having absorbed heat from the internal combustion engine 1 and air; a cooling passage 41 for the electrical component which cools the electrical component 2 by circulating the coolant having flown out from the heat exchanger 3; a cooling passage 42 for the internal combustion engine which cools the internal combustion engine 1 by circulating the coolant having flown out from the cooling passage 41 for the electrical component; a bypass passage 44 which leads the coolant having absorbed heat from the internal combustion engine 1 to an inlet side of the cooling passage 41 for the electrical component while bypassing the coolant to the heat exchanger 3; and a bypass passage side opening and closing valve 440 which opens and closes the bypass passage 44. |
