摘要
介绍了接触热阻的概念,搭建了一套接触热阻试验平台,针对燃油与金属壁面的接触状况进行了试验测试,得到固液界面的等效导热系数,进而通过理论公式计算出接触热阻,为飞机油箱温度场分析提供保障。
In this paper,the concept of thermal contact resistance is introduced,and a set of test platform for thermal contact resistance is built.The test of contact between fuel and metal wall is carried out.The equivalent thermal conductivity of solid-liquid interface is obtained by test,and the thermal contact resistance is calculated by theoretical formula,which provides the guarantee for the temperature field analysis of aircraft fuel tank.
