径向热管传热的数值计算及结果分析

Analysis and calculation of radial heat pipe heat transfer

采用计算流体力学软件首先对无吸液芯径向热管管壁的温度进行数值计算,其次模拟无吸液芯径向热管中蒸汽的层流对流换热的情况,得出其温度场分布和速度场分布,并对结果进行分析。

At first, wall temperature of radial heat pipe without wick was calculated by hydrodynamics software. Second, interior steam heat transfers were simulated. Temperature and velocity distribution of interior steam were obtained and their mecha- nism were explained.
