Abstract:

An experimental study was carried out to investigate the thermal performance of a new type of copper wire-bonded flat heat pipe.The influences of working fluid，steam temperature，wire diameter and wire gap on the thermal performance of the heat pipe were investigated to design the optimal construction.Experimental results showed that wire diameter had an important effect on heat transfer but hardly had any impact on maximum heat flux.The wire gap not only had an important effect on heat transfer but also had a significant impact on maximum heat flux.

摘要：

对一种铜丝结构的新型微槽道平板热管的换热特性进行了实验研究，实验在40、50和60℃ 3个稳定的管内蒸气温度条件下进行，实验工质为去离子水和乙醇。实验研究了铜丝直径、铜丝间距、实验工质和蒸气温度对热管换热特性的影响，为此新型热管在实际工程中的应用提供了设计依据。
