Abstract
A semiconductor device in which the lifetime of mounted components can be prolonged. A cooling system for controlling the temperature of a refrigerant through a heating section and a radiator is provided. The semiconductor device is connected to the cooling system and is cooled. A variation width (ΔT1) of temperature controlled by the cooling system through the heating section and the radiator is smaller than a temperature variation (ΔT2) of the refrigerant caused by variations in operating conditions of the semiconductor device (ΔT1≦ΔT2).
