摘要
半导体制冷器由于材料限制， 主要应用于２００ Ｋ左右的中低温领域。通过低温热管相连， 利用辐射制冷器冷却半导体制冷器热端， 将其热量直接辐射到宇宙空间中， 使其维持在２００ Ｋ温度， 将可能使冷端达到接近１００ Ｋ的空间实用化低温。对这种半导体制冷器／热管／辐射制冷器的复合制冷系统， 空间使用的可行性做出简单分析。
Semiconductor coolers are usually used in medium low temperature on account of their material limit.If a radiant cooler is connected to the heat end of a semiconductor cooler by a cryogenic heat pipe,the radiant cooler will radiate the heat dissipation of the semiconductor cooler directly into the cosmos and make its heat end keep at 200 K,then the cold end of the latter will probably be cooled to 100 K,which is an applicable space temperature.Analysis of the feasibility of this kind of compound space cooling system—semiconductor cooler/heat pipe/radiant cooler will be shown.
