摘要
A cooling apparatus which has a simple structure and which can efficiently cool a plurality of electric devices is disclosed. The apparatus comprises a cooling circuit including serially-connected cooling systems for cooling electric devices by circulating a refrigerant; a circulating pump for circulating the refrigerant through the cooling circuit; and a radiator which is serially connected to the cooling systems in the cooling circuit and has a refrigerant outlet from which a refrigerant is supplied. The serially-connected cooling systems are arranged in a manner such that heat resisting allowable temperatures, assigned to the electric devices which respectively correspond to the cooling systems, increase from the cooling system closest to the refrigerant outlet to the cooling system farthest from the refrigerant outlet in the cooling circuit, wherein each heat resisting allowable temperature is the maximum temperature at which the relevant electric device can operate.
