Abstract
The imaging quality of the remote sensing camera is directly related to the thermal design of CCD. The cycle average thermal control power required by CCD is 1/3 of the whole remote sensing camera under traditional temperature control solution. with the resolution of the remote sensing camera is increasing. Thermal control of CCD components could be a bottleneck in the thermal control of the camera. According to the temperature control requirements of CCD devices , the temperature control scheme of CCD using semiconductor and phase change heat pipe is proposed for the first time. Simulation analysis and experimental verification are carried out on the key components of the temperature control scheme .based on the simulation analysis and experimental verification of key components, the system simulation model was established ,and the relationship between the phase transition temperature and the area of the radiator is obtained by simulation. System simulation results show that the thermal control scheme can meet the requirements and the temperature of the CCD is between 18℃ and 21.5℃. The radiator area is only 16% of the traditional program. The cycle average power consumption under high temperature condition is only 5% of the traditional scheme. the cycle average power consumption under low temperature condition is only 16% of the traditional scheme. the temperature stability of the CCD during imaging period can be improved one order higher by adjusting the starting strategy of the remote sensing camera to ±0.2℃.
