In order to keep the temperature of CCD assembly, a heat dissipating scheme and precise tem-perature control strategy for high-power CCD assembly are studied by simulation according to the structure characteristics of the focal plane apparatus. The requirements of the thermal design of high-power CCD assem-bly are introduced and the feature of thermal design of high-power CCD assembly is analyzed. The technology based on micro heat pipe is introduced to solve the thermal dissipation problems.The temperature control strategy is proposed based on the integral-separated PI active thermal control. The thermal performance is simulated by means of Thermal Desktop. The results show that using of active thermal control heating and regulation systems can meet the strong requirements in terms of thermal stability and temperature levels.
