空间模拟设备GM制冷机组合式冷屏设计

SPACE SIMULATION FACILITY DESIGN OF THE BUILT-UP REFRIGERATED SCREEN OF THE GM REFRIGERATED

空间环境模拟设备中采用多台GM制冷机组合式冷屏是一个新课题。介绍了GM制冷机组合式冷屏的设计、冷头浮动式安装结构、组合式支撑等,并对冷屏漏热作了详细计算。

The adoption of several built-up refrigerated screens of the GM refrigerator in space environment simulation equipment is a new topic. The thesis introduces the design of the built-up refrigerated screens of the GM refrigerator, the floating installation structure of refrigerated head, and the built-up bonding. It also gives a detailed calculation about heat leak of the refrigerated screen.
