摘要
设计建立了一套以水为工质的分离式热管系统实验台,系统冷凝端采用水冷套管式换热器。在此实验台基础上研究了不抽真空,有大量不凝性气体空气存在于分离式热管的蒸汽凝结放热问题。测定了不同的蒸汽入口温度、循环蒸汽流量、冷却水进口温度及流量四种情况下混合气体在圆管内凝结放热的情况,分析了这些参数对换热过程的影响。
A set of separate heat pipe （SHP） with water as medium has been built in this paper. The flow and condensation of vapor with non-condensable and high partial pressure air in the SHP are measured in the experiment. A series studies are made of the effect on the parameters-coolant water flux, vapor flux, the coolant inlet temperature and the inlet vapor temperature and a lot of reliable data are obtained to analyze the heat transfer process.
