APPLICATION OF THE FINITE ELEMEMT ANALYSIS IN THERMAL ANALYSIS OF RADIANT COOLER

Radiant cooler mostly provides cryogenic working condition for the infrared detector.It is an important part of space infrared remote sensing detect system.The finite element analysis model of W radiant cooler has been set up.Thermal transmutation analysis of radiant cooler is done by ANSYS analysis software.The measure for minishing two cold head comparatively displacement is introduced.As a result of analysis,it offer a theory reference for the optimal design of radiant cooler and optics compensate of infrared camera.
