PURPOSE:To cool refrigerant medium to improve a compression efficiency by a method wherein the heat dissipating amount of one rise-up part of a heat dissipating pipe is made bigger than the same of the other rise-up part and the opening end of the pipe having bigger heat dissipating amount is arranged immediately above a refrigerant medium suction path in the enclosed compressor. CONSTITUTION:The refrigerant medium gas, discharged from a compression mechanism 9, is sucked again into the compression mechanism 9 from an enclosed vessel 6 bia a discharging pipe 13 and passing through a condenser 14, a pressure reducer 15 and an evaporator 16. On the other hand, the refrigerant medium, cooled and liquefied in a descending part 10a in a heat dissipating device 10, which is having a high heat dissipating capacity, is returned to a place 11 immediately above the refrigerant medium suction path 17 side of the compression mechanism 9 in te enclosed vessel, therefore, the refrigerant medium suction path 17 is cooled directly and the compression efficiency may be improved. |
