PROBLEM TO BE SOLVED: To provide a refrigerator, which has an improved heat-exchange efficiency, a great capacity, and less power consumption. SOLUTION: In a low temperature side heat-exchanger part 10, cold heat generated in a low temperature part 3 of a Stirling refrigerator 1 is transferred to a low-temperature side condenser 4, and refrigerant is almost liquefied. The refrigerant of a liquid-gas mixture is conducted through a copper pipe 12 to a low-temperature side gas/liquid separator 6 by using the difference in the height between the condenser 4 and the separator 6, and the liquid is collected in the separator 6. The liquid refrigerant is conducted further from the bottom of the separator 6 through a copper pipe 13 to a low-temperature side evaporator 5, and the cold heat is heat-exchanged with the air in the refrigerator through the wall-face of the evaporator 5 to generate cool air in the chamber. In a high-temperature side heat-exchanging part 11, hot heat is released in the same principle. |
