Abstract
A cooling system mounted in a vehicle includes a radiator exchanging heat with the outside air; first and second flow paths; and a control device. The first path is configured so that when the first pump is operating, a heat medium circulates through the radiator and a first heat exchanger exchanging heat with the inverter. The second flow path is connected to the radiator in parallel with the first flow path, and is configured so that when the second pump is operating, the heat medium circulates through the radiator and a second heat exchanger exchanging heat with the battery. The control device controls the outputs of the first and second pumps so that when making both of the outputs rise or fall, the flow rate of the heat medium flowing through the first flow path becomes temporarily larger than the target flow rate.
