| Abstract: | In order to meet the thermal vacuum test requirements of a certain aerospace product, a special temperature-controlled heat sink is designed, which consists of a heat sink, a heater and a supporting temperature control system. This paper briefly describes the design of a special temperature control heat sink for a certain product, and carries out simulation analysis and verification of the structure. The analysis results show that, when the product heat is 200 W, the space temperature can be higher than +120℃, the heat sink body temperature can be lower than-180℃, with temperature control conditions. The temperature control system adopts PID adaptive adjustment. The results show that the space temperature can be controlled from-180℃ to +120℃, and the temperature control accuracy can reach ±0.5℃, which meets the test requirements. |
