THE THERMAL ANALYSIS OF THE SYSTEM FOR LINKING BETWEEN MECHANICAL CRYOCOOLER AND INFRARED DETECTOR

In the spaceborne infrared remote sensing system,the infrared detector is linked with the cryocooler,so that it can be cooled down to and kept at its working temperature. lt is important for the system to reduce the heat leakage and improve the efficiency of heat transfer.In this paper,used a specific software of finite element analysis to solve those thermal problems.From the results,can optimally design the system.
