Abstract
A cooling apparatus for a vehicle for cooling a high-voltage device group mounted on the vehicle includes a radiator mechanism including a first radiator, a fan disposed adjacent to the first radiator, and a second radiator disposed between the first radiator and the fan. A first refrigerant circulation circuit performs heat exchange with a first group device in the high-voltage device group by circulation of a first refrigerant which radiates heat by the first radiator. A second refrigerant circulation circuit performs heat exchange with a second group device in the high-voltage device group by circulation of a second refrigerant which radiates heat by the second radiator. A chiller circuit includes a chiller where the chiller circuit includes a communication circuit which causes a downstream side of the chiller and an upstream side of the first radiator to communicate with each other through a flow-passage switching valve.
