PURPOSE: To prevent the burning of an electric motor and separate oil surely from discharging air in the compressor in the caption by connecting a heat radiation pipe to a discharge cover mounted on a fixed scroll for covering a discharge hole and providing an oil cooling pipe whose one end is dipped in lubricating oil and the other each is led out from a closed container.
CONSTITUTION: One end of a radiation pipe 18 is connected to a discharge cover 14 mounted on a fixed scroll 4 for covering discharge hole 11. The other end is connected in the vicinity of electrically driven element 9 via a radiator 19. An oil cooling pipe 20 comprising a heat pipe dipped in lubricating oil 2 at its one end and led out from a closed container 1 at its other end is provided. The air compressed to have a high temperature is cooled once by the radiator 19 and introduced again into the inside of the closed container. In this manner, the cooling of the electrically driven element 9 is performed surely surely and the burning of an electric motor is prevented and the oil is separated surely from the discharging air.
