Even if a high-voltage device cooled by a radiator needs a cooling capacity larger than ordinary at emergency, a cooling capacity thereof is easily increased without making a system redundant. The cooling apparatus for vehicle includes a radiator mechanism 10 including a first radiator 12, a second radiator 13, and a fan 14, a first refrigerant circulation circuit 30 for cooling a first group device 60a by circulation of a first refrigerant which radiates heat by the first radiator 12, a second refrigerant circulation circuit 40 for cooling a second group device 60b by circulation of a second refrigerant which radiates heat by the second radiator 13, a chiller circuit 50 in which a communication circuit 52 is formed for causing a downstream side of the chiller 11 and an upstream side of the first radiator 12 to communicate with each other, and a VCU 20 for determining a cooling capacity of the second refrigerant circulation circuit 40, in which the VCU 20 causes the communication circuit 52 to communicate when the cooling capacity is insufficient.
