纵向翅片扁管的传热性能分析

Performance Analysis of Vertical Fin and Flat Tube Heat Transfer

本文运用FLUENT软件对纵向翅片扁管进行数值模拟,对翅片的长度、高度、间距在不同进口参数下翅片表面的传热和流动性能进行比较,得出有效翅片长度受速度的影响,翅片间距与换热系数成正比,与空气流道压降成反比。为强化纵向翅片扁管传热提供参考。

A simulation of vertical fin and flat tube is carried out using FLUENT software compared with heat transfers and flow performances of fin surface at different import parameters to length.Obtained the effective fin length by the velocity,the fin pitch is proportional to the heat transfer coefficient,inverse to pressure drop.The reference is provided for enhancing the heat transfer of vertical fin and flat tube.
