辐射致冷是60年代兴起的一种航天器红外遥感系统的致冷方法。因为致冷器重量轻、寿命长、无转动部件、不需要贮存冷液、仅消耗微小的电源作温控使用,因此,这种致冷手段受到了国内外航天部门的普遍关注。但是,在理论和工艺上辐射致冷还有一定的难度, Radiation refrigeration is a kind of refrigeration method of spacecraft infrared remote sensing system which arisen in 1960s. Because the refrigerator is light weight, long life, no rotating parts, no need to store cold liquid, only consume a small amount of power for temperature control use, therefore, this refrigeration means by the domestic and international space sector’s widespread concern. However, the theory and technology radiation cooling there is a certain degree of difficulty,
