Abstract:

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.

Key words: thermal design;methord of finite element;optical solar reflector;thermal balance test
