微肋管结构对管内冷凝换热影响的研究

Research on the impact of micro-fin tube geometrical parameters on condensation

相对于光管,微肋管的结构参数相对较多,这些结构参数的变化会不同程度地影响微肋管的换热能力,国内外的很多学者进行了研究,但结论相差较大,甚至完全相反。因此本文对这些研究成果进行一定的分析和回顾,希望能为铜管生产厂商以及空调设计工程师提供相关的参考,也为今后的研究工作提供一定的借鉴。

Compared with smooth tube, micro-fin tube has more geometrical parameters that influence heat transfer to different extent. Many scholars has done much work on it, but some research results are different or even contradictable. So makes an analysis and review on how the parameters influenced heat transfer, hoping that would give some guides to the tube manufacturer and air conditioner design engineer.
