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

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.
