Abstract: A vehicle heat exchange system includes a cooling heat exchanger provided in a cooling water circuit, a first air-conditioning heat exchanger as an evaporator in a heat pump system, a hydrothermal-medium heat exchanger as a refrigerant condenser in the heat pump system, a second air-conditioning heat exchanger, and an air conditioning passage in which the first air-conditioning heat exchanger and the second air-conditioning heat exchanger are disposed. A vehicle interior-exterior communication port is provided at a downstream side of the second air-conditioning heat exchanger in the air conditioning passage, to guide the air having passed through the second air-conditioning heat exchanger, to an outside of the vehicle interior. The cooling water for cooling the heating element flows through the second air-conditioning heat exchanger, and the air having passed through the second air-conditioning heat exchanger is discharged outside the vehicle interior through the vehicle interior-exterior communication port.

Abstract: A cooling system includes multiple heat exchangers, a shutter, and a controller. The controller determines whether an amount of air flowing to the other heat exchanger needs to be increased and controls an opening degree of the shutter in a closing direction to reduce an amount of air flowing to a specified heat exchanger and increase an amount of air flowing to another heat exchanger upon determining that the amount of air flowing to the other heat exchanger needs to be increased.
