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

摘要: 辐射制冷器主要为红外探测器提供合适的低温工作条件,是星载红外遥感探测系统的重要组成部分。建立了W型辐射制冷器的有限元模型。利用AN SYS分析软件对辐射制冷器热变形进行了分析,提出了减小2个冷头相对位移的措施,为辐射制冷器的优化设计和红外相机的光学补偿提供了理论依据。

Abstract: 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.
