摘　　要：对某型号卫星搭载的W型辐冷器的热地面热环境模拟试验情况作了详细介绍,重点对其可能产生的误差进行了深入的分析。通过对比热环境模拟试验测试数据以及在轨遥测数据,分析得出两者之间的相对误差在1%左右,证明验证辐冷器性能的热环境模拟试验方案是合理的、准确的。The thermal environment experiment of a W type radiant cooler was introduced. The focus was the error analysis of the measured data. By comparing the measured data in thermal environment experiment and telemetric data on orbit, the result showed that the error of two groups data was about 1%. The accuracy and the reasonableness of thermal environment experiment were proved.
