Abstract

Charge Coupled Device(CCD) in vacuum environment could be easily overheated, and the energy is not equally distributed on the surface. So the thermal design of the CCD plays a significant role in the procedure of the whole detection[1]. If a proper method is used for the cooling of the CCD, the temperature distribution would be more equally on the surface and the testing result of the CCD would be more accurate. In this paper, a thermal control system for CCD camera in vacuum was designed. CCD will be placed in a cavity filling with high-specific heat capacity gas, so that the energy generated from CCD could be reserved in the gas through thermal convection and heat radiation. In order to reduce the gas leakage, multilayer cavity was designed to maintain the gas pressure of the cavity. The result shows that the optimized multilayer cavity structure for cooling system of CCD can reduce overheated of CCD significantly with CFD (Computational fluid dynamics) method.
