PROBLEM TO BE SOLVED: To provide a heat exchange system capable of ensuring cooling efficiency of an electric system by its simple configuration and improving drive efficiency of air-conditioning.SOLUTION: An electric system coolant for cooling an electric system of a vehicle circulates in an EV cooling circuit 3. A air-conditioning coolant circulates in a heat pump type air-conditioning coolant circuit 2. The EV cooling circuit 3 includes a radiator 5. The heat pump type air-conditioning coolant circuit 2 includes a capacitor 4. The radiator 5 and capacitor 4 compose a heat exchanger 6. The heat exchanger 6 performs heat exchange between the electric system coolant and air-conditioning coolant. A switching unit makes the electric system coolant and air-conditioning coolant flow in the heat exchanger 6 in the same direction during cooling, and makes the electric system coolant and air-conditioning coolant flow in the heat exchanger 6 in the directions reverse to each other during heating. |
