Description of the Related Art As shown in FIG. 2, for example, a refrigeration cycle of a conventional refrigerator is connected to a compressor 1 having a refrigerant discharge side 1a and a suction side 1b, and connected to the discharge side 1a of the compressor 1. Oil cooler condenser 6 and oil cooler condenser 6
From the outlet side of the compressor 1 to the inlet side of the oil sump 5a ', and connected to the main condenser 2' from the outlet side of the oil sump 5a 'to form an oil cooler 5'. The capillary tube 3 connected to the outlet side of the 'and the evaporator 4 are sequentially circulated to form a refrigeration cycle. In the above configuration, when the compressor 1 is operated, the high-temperature and high-pressure refrigerant discharged from the compressor 1 is cooled to some extent by the oil cooler condenser 6 and then provided again in the oil sump portion in the compressor 1. Lead to 5 ', lower the temperature of hot lubricating oil. The refrigerant that has exited the oil cooler 5 ′ is condensed and liquefied by heat exchange with outside air in the condenser 2 ′, and flows into the capillary tube 3. The refrigerant is decompressed in the capillary tube 3, evaporated in the evaporator 4, exchanges heat with the air in the storage, and is vaporized to cool the storage. However, in this oil cooler system, the condenser 2 '
Since a part of the heat radiating pipe is used for an oil cooler, the heat radiating pipe has a disadvantage that the main heat radiating pipe is shortened and the amount of heat radiated is reduced.

When the compressor 1 is operated, the high-temperature and high-pressure refrigerant discharged from the compressor 1 is condensed and liquefied by exchanging heat with the outside air in the condenser 2.
It flows into the capillary tube 3. The refrigerant is decompressed in the capillary tube 3, evaporated in the evaporator 4, exchanges heat with the air in the storage, and is vaporized to cool the storage. Once the refrigerant discharged from the evaporator 4 passes through the oil cooler 5 provided in the compressor 1 once, the refrigerant in the suction pipe surely enters a gas state, and the temperature of the high-temperature lubricating oil of the compressor 1 Lower.
