穿孔翅片是一种高效换热表面.它对于提高空气冷凝器、回热器等的性能具有实际意义。但在发表的文献中,通常把穿孔翅片的传热过程简化成单纯的对流系统,并未注重它的传热实为传导-对流系统这一基本事实,即没有研究穿孔翅片效率的变化及其影响。本文在传导-对流系统下进一步研究穿孔翅片的强化传热及流动阻力并分析比较 Perforated fins are efficient heat exchange surfaces and have practical implications for improving the performance of air condensers, regenerators and the like. However, in the published literature, the heat transfer process of perforated fins is usually simplified to a simple convection system, without paying attention to the fact that its heat transfer is actually a conduction-convection system. That is, the change in efficiency of perforated fins has not been studied And its impact. In this paper, conduction-convection system to further study the perforation fin heat transfer enhancement and flow resistance and analysis and comparison
