| 摘 要： | 为了对辐射器传热效率进行有效评估,从局部肋效率公式入手,通过肋根温度和等效热沉温度的平均,获得流体回路-热管混合式辐射器的系统传热效率的解析公式.与数值计算结果进行比对分析,证明两者的偏差小于7%.该公式避免了复杂的数值计算,可用在工程计算中对空间热辐射器的系统传热效率进行评估.

| Abstract: | Based on the local fin efficiency formula,the mean temperature of fin root and the mean equivalent temperature of heat sink,an analytic formula for estimating the heat transfer efficiency of a space radiator combined by fluid loops and heat pipes is presented.By comparison,it is found that the deviation between the analytic result calculated by the presented formula and the results obtained by numerical simulation is less than 7%.This formula is simple and can be used to estimate the heat transfer efficiency of the radiator in engineering applications. |
