该文采用加热石英玻璃管和无缝钢管模拟分离式热管的蒸发段,对合理的充液率、流动和传热特性进行了系统的试验和理论分析。作者着重分析了核态沸腾传热区及飞溅降膜区的换热原理,根据试验数据回归整理了相应的换热系数无量纲准则关系式,与试验数据吻合较好;同时将这两个关系式分别与大空间池沸腾传热及整体式热管蒸发段降膜传热区传热进行了比较,得出了极为有用的结论.图7参3
In this paper, heated quartz glass tube and seamless steel tube are used to simulate the evaporating section of the separated heat pipe, and the reasonable test of the liquid filling rate, flow and heat transfer is carried out systematically and theoretically. The author focuses on analyzing the heat transfer principle of the nucleate boiling heat transfer zone and the splash falling film zone. According to the test data, the corresponding heat transfer coefficient dimensionless criterion relation is concluded, which is in good agreement with the experimental data. At the same time, Respectively, with large space pool boiling heat transfer and integral heat pipe evaporation section of the falling film heat transfer area were compared, reached a very useful conclusion.
