| 摘 要： | 给出了求解典型圆柱状态含液体介质的空间辐射器传热效率的解析计算公式,降低了辐射器传热效率计算的复杂度,通过与数值计算结果的比对分析,认为用流体入口温度代替辐射器平均温度的假设在工程上是能够接受的,其引起的偏差小于5%。 |

| Abstract: | A simple analytic formula for estimating the heat transfer efficiency of cylindrical space radiators with fluid loops was presented.It was found that the deviation between the results calculated by the formula and that obtained by numerical simulation was less than 5%.So,the hypothesis that inlet temperature Tfi substitutes for the mean temperature Tm is acceptable in engineering. |
| Keywords: | Space radiators Fluid loops Heat transfer efficiency Spacecraft |
