本文报道空气横向掠过花瓣状翅片管的传热强化实验研究结果，分析比较了七种花瓣状翅片管（翅间距Ｐ／Ｄｏ＝０．０５２６～０．１３２，翅片高ｈ／Ｄｏ＝０．０９４７～０．１２６）的传热强化机理与性能，给出了包括翅片参数在内的传热准数与流体阻力系数关联式，找出了较佳翅片参数范围。本文还比较了花瓣状翅片管与波纹状高翅片管的传热强化性能，比较结果表明，花瓣状翅片管在节省空气换热器管材消耗方面明显优于波纹状高翅片管。 This paper reports the experimental results of heat transfer enhancement of petal-like finned tubes transversely across the air. Seven fin-shaped finned tubes (P / Do = 0.0526-0.132, f / h = 0.0947 ~ 0.126) heat transfer enhancement mechanism and performance, given the heat transfer criteria, including the fin parameters, and the fluid resistance coefficient correlation, to find a better range of fin parameters. The paper also compares the heat transfer enhancement between the petal-like finned tube and the corrugated high-finned tube. The results show that the petal-shaped finned tube is obviously superior to the corrugated finned tube in saving the air tube heat exchanger.
