摘要: 以去离子水和水基铜纳米流体为工质,对一种铜丝丝网平板热管的传热特性进行了实验研究.分析了不同工作压力、不同工质和纳米流体质量分数对铜丝丝网平板热管传热性能的影响,并与单一铜丝平板热管的换热性能进行了比较.结果表明:纳米流体在低压条件下可以显著提高热管的换热特性,是一种适用于平板热管的新型工质;在使用水和纳米流体2种工质的实验中,铜丝丝网平板热管的各项换热功能指标均优于铜丝平板热管,并且热管热阻明显降低,最大功率也明显增加.

Abstract: The heat transfer characteristics of a novel flat heat pipe, the copper wire-bonded and mesh screen flat heat pipe ,were investigated experimentally. The effect of various working pressures, nano-fluid concentration and working fluids which include deionized water and waterbased copper nanofluids on copper wire-bonded and mesh screen flat heat pipe was analyzed. Besides, the performance was compared to that of copper wire-bonded flat heat pipe. The results show that nanofluid under low-pressure conditions can significantly improve the heat transfer characteristics of heat pipe and is a new working medium which can be applied to flat heat pipe. The overall thermal performances of new heat pipe are superior to those of copper wire-bonded flat heat pipe, the thermal resistance reduces distinctly and the maximum power increases obviously.  

Key words: flat heat pipe; nano-fluid; heat pipe with mesh screen structure, heat transfer
