【摘要】 本文针对地球静止同步辐射制冷器,在一年的某些季节会受到阳光的照射, 如何控制其对辐射制冷器的影响,是提高制冷性能的技术关键。采用蒙特卡罗光线跟踪的方法,对太阳屏接受阳光加热进行了理论分析,并提出了解决措施。通过在轨性能和地面热模拟试验的对比,验证了理论分析是合理的,解决措施是有效可行的。更多还原

【Abstract】 From the frame of reference of a geosychronous satellite the sun would appear to move up and down within some season, causing the sun to move into and out of the radiant cooler field of view seasonally. How to controlling the affection to the patch of the cooler is important for improving the cooling performance. After analyzing the radiation heat quantity absorbed by the sunshield from the sunshine through the Monte Carlo method based on the statistical principle, an efficient measure to control its temperature is given in this paper. Though comparing the performances in the orbit and the thermal vacuum test, the analysis method and the measure for improving is reasonable.更多还原
