摘要
空间遥感器直接面向轨道热环境 ,热设计十分复杂。 CCD子系统作为成像的重要组成部分 ,热设计的好坏直接关系到成象的质量。本文分析了此空间遥感器 CCD组件的热传递路径和热工程设计 ,重点对热设计组件热管辐射器进行了设计计算和热辐射校核 ,最后把此组件代入整机有限元分析模型进行了热分析 。
Space remote sensor directly faces space thermal vacuum environment, so its thermal design is very complicated. As one of its important subsystem, CCD component subsystem's thermal design determines the image quality to some extent. Heat path and thermal engineering design of CCD component subsystem were presented in this paper. As the most important parts of this theraml design, design calculation and radiation capability of heatpipe radiator were discussed in this paper. Finally, the thermal component was put into all the thermal FEM model, which was proved that the design is good.
