本文通过实验和理论分析研究了两相闭式热虹吸管加热段的换热规律及两相流对加热段换热的影响.结果表明,对流换热区换热的强化是加热段有较高的换热系数的主要原因;加热段长度对加热段的平均换热系数有明显的影响,较短的加热段有较高的换热系数.
In this paper, the heat transfer law of two-phase closed thermosyphon heating section and the effect of two-phase flow on the heat transfer in the heating section are studied through experimental and theoretical analysis.The results show that the enhancement of heat transfer in the convection heat transfer section is higher The main reason of the heat transfer coefficient is that the length of the heating section has a significant effect on the average heat transfer coefficient of the heating section and the shorter heating section has a higher heat transfer coefficient.
