A combination product of a power inverter and a dielectric refrigerant composition for a power inverter, a dielectric liquid refrigerant composition, and a method for cooling a power inverter for an electric traction motor are provided to prevent the corrosion of an aluminum electronic part. A combination product of a power inverter and a dielectric refrigerant composition for a power inverter comprises a power inverter which contains an aluminum constitution unit such as an electronic part; and a refrigerant composition which comprises a liquid mixture of an oligo-(alkyl siloxane) and an alkyl ether alkylene glycol and an azole compound dispersed in the liquid mixture, wherein the azole compound is contained in such an amount for inhibiting the dissolution of the aluminum constitution unit.
