高导热石墨薄膜真空环境下导热性能测试验证
Thermal conductivity test and verification of high thermal conductive graphite film under vacuum environment
摘要
Abstract
Excellent thermal conductivity of graphite film makes it a good candidate for the heat dissipation of high power consumption electronic equipment onboard spacecraft.However,due to its susceptibility to slagging,powdering,and poor stability,it may not be directly applied to spacecraft thermal control systems.Therefore,packaging the graphite film was proposed,and the performance of the prepared packaged graphite film was tested in this paper.It is shown that packaging the graphite film solves the problems of slagging and powdering.Subsequently,the packaged graphite film was utilized to a satellite single unit equipment.The in-orbit and simulation data show that the maximum temperature of a posture-orbit control extension unit decreased by 7℃compared with that of unpackaged graphite film,and the maximum temperature of the other type of transponder decreased by 8.5℃,achieving the purpose of thermal control.Thus,the packaged graphite film may be potentially used in spacecraft equipment for desirable heat dissipation.关键词
