低温水热管的特性研究

Study on Temprature Charcter of Water Heat Pipe

比较了几种工质在近室温范围的性能并对２０～６０℃的水热管特性进行了研究，认为在该温度区间水仍为较合理工质，实验测得了２０～６０℃水热管的换热系数及最大热流密度，并整理出了该研究范围的热管蒸发段和冷凝段换热特性的关联式。

After compared the ability of several kins of working fluid and systematiallyinvestigated water heat pipe at 20～60℃, water is confirmed a reasonable working fluid,this paperacquired values he; hc.qmax of water heat pipe at 20～ 60℃ by experiments and maked out experi-mental relationship formulas abeu t the evaporative range and the condensed range.
