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.
