In order to test the heat balance of a certain type of camera, simulation analysis of the solar simulation lamp under vacuum environment was made. According to the requirement of thermal equilibrium test, the technical requirements were put forward. The finite element analysis of the rigidity and stress distribution of the key structure was carried out. According to the finite element analysis Results The design was optimized to meet the rigid requirements of the key structural parts. The main technical problem was the lamp thermal conductivity. For this problem, the active control technology was adopted and the thermal conduction mechanism was specially designed to make full use of the high thermal conductivity of the thermal pipe, A scientific and reasonable finite element thermal model was established for thermal analysis. The thermal design of solar simulation lamp structure was accomplished by simulation of heat pipe heat transfer technology, which solved the problem of thermal conductivity when using solar simulation lamp.
