Abstract

In a CCD camera system, the CCD sensor must be cooled to low temperature to reduce the dark current. Many factors will affect the cooling performance as we use TEC. Therefore, quantitative analysis of the effects of the various factors on the cooling performance is very important for designing the cooling structure of the CCD vacuum head. In this paper, the length and diameter of the wires between the CCD and the vacuum feedthrough, the thickness of the cold end, and the vacuum degree are taken into consideration and analysis. Through the simulation, useful conclusions are obtained to guide the machanics and cooling design of the CCD vacuum head.
