Abstract
To improve the performance of aircraft precision instrument, a temperature control system with passive heat dissipation and active temperature control was designed. In the system, the heat pipe and radiation coating were used as passive radiator to transfer the heat from the instrument. The first stage temperature control was established by semiconductor cooler and insulation layer, and the second stage temperature control was established by electric heating device. The control logic was designed to control temperature. A verification test platform was built, and the temperature control accuracy of the temperature control system under different operating conditions was tested. The result shows that the temperature control accuracy of the system is within ±0.1℃ under the conditions of different environmental temperatures and system setting temperatures.
