Abstract:
1. A Stirling refrigerator comprising: a Stirling refrigerating device including a heat absorber for absorbing heat from outside air, a heat-absorbing heat exchanger for prompting heat absorption by the heat absorber, a heat rejecter for rejecting heat to outside, and a heat-rejecting heat exchanger for prompting heat rejection by the heat rejecter, the Stirling refrigerating device cooling an interior of the refrigerator by absorbing heat through the heat absorber by a process of a reversed Stirling cycle, wherein dew prevention heat pipes are, at one end, coupled to an end surface of the heat rejecter, or to an end surface of a ring-shaped member made of a high-thermal-conductivity material and fitted around the heat rejecter, by being inserted in a plurality of small holes formed in the end surface of the heat rejecter or formed in the end surface of the ring shaped member and are, at another end, located at an open side of the refrigerator so that, as the Stirling refrigerating device is operated, waste heat rejected from the heat rejecter is transferred by way of the dew prevention heat pipes to heat the open side of the refrigerator.
