摘　　要：提出了一种新型拼接式太阳屏的三级辐射制冷器概念,可有效提高制冷器的制冷效率。完成了样机研制,地面热模拟试验制冷性能:夏至有阳光时100 K/67 mW,无阳光时85 K/47.4 mW和90 K/86.4 mW,可以满足多元探测需求。A new type of three stages radiant cooler was developed which had higher cooling efficiency than a usual one. Tests were finished and thermal simulation test indicated that the capacity was 67 roW/ 100 K at the solstices and 47.4 mW/85 K （or 86.4 mW/90 K） at the other time.
