Abstract
A compressor included in a refrigerative cycle is disposed in a refrigerator with a rear plate and side plates. The cooling device for the compressor includes a thermo-siphon which includes a closed pipe loop disposed independent of the refrigerative cycle to cool the compressor. The thermo-siphon contains a gaseous liquid refrigerant corresponding to 60% to 80% of the inner volume of the closed pipe loop and has a heat absorbing portion immersed in an oil stored in the compressor and a heat discharging portion at least a part of which thermally contacts the rear plate or the side plates.
