摘要
介绍了航天用中继测控射频模块的热设计方法,针对设备实际应用环境提出了热设计方案以及工艺实现方法,同时采用有限元法对设备进行了热仿真优化。对样机进行了试验测试,几款功率器件结温均满足航天降额要求,保证了产品在其工作环境的长期可靠性,并通过热平衡试验验证了工艺措施和热仿真的合理性与可行性。
This article mainly introduced the thermal design method of the Relay Monitoring and Control RF module for Aerospace Applications, put forward thermal design process and implementation method according to application environment of equipment, at the same time thermal simulation is carried out using the finite element method （FEM） on the equipment optimization. On the prototype test, The junction temperature of power devicescan satisfy the requirements of derating for space application, the rationality and feasibility of thermal simulation and implementation method is verified by thermal balance test.
