摘　　要：在充分考虑槽道内汽-液界面剪切摩擦力下,建立了微小型矩形槽道平板热管的数学模型,通过迭代计算得出工质质量流量、流体和蒸汽平均流速、汽一液界面弯月面半径及蒸汽和液体压力沿轴向分布规律,最后对热管外壁面温度值的计算结果和实验结果进行了比较,两者数值基本一致,证明了所建数学模型与实际相符,对热管的理论分析具有指导意义。considering fully the friction of the vapor - liquid interfaeial shear force, the micro and small rectangular flat heat pipe channel mathematical model was established. The refrigerant mass flow, average flow rate of fluid and steam, gas - liquid interface meniscus raius and steam - liqiud axial distribution were calculated by iteration method. In comparison of calculation result and experiment result, they are basically the same. It shows the mathematical model accords with the practical application.
