摘　　要：设计了1种新型辐射制冷器级间纤维支撑系统,介绍了其结构的设计,支撑材料的选择以及纤维接头的研制。利用MSC. Nastran有限元软件对系统进行准静态结构强度和纤维预紧力进行了分析。级间漏热的理论分析结果表明此纤维支撑系统为研制更大冷量的辐射制冷器提供了可能。An innovative fiber support system（FSS）was introduced. Its structural design, material selection and fiber fastener design were described. The static analysis of FSS was accomplished using MSC. Nastran software. The amount of pre-tension on fibers was predicted. Further more, the theoretical results of conducted parasitic heat loads indicate that FSS has great potential in enhancing cooling capability of radiant coolers.
