| 摘 要： | 风洞试验台上对8种不同结构参数的百叶窗翅片进行传热和流动阻力的性能试验。分析比较了翅片长度、翅片间距、翅片高度对其传热和阻力性能的影响，其中翅片长度和翅片间距对无量纲传热j因子和摩擦阻力f因子影响较大，翅片高度影响较小。同时采用3√j/f因子综合评价了8种翅片的强化传热效果。结果表明，翅片长度对强化传热影响最为显著。

| Abstract: | Experimental study on heat transfer and flow resistance of louver fins with 8 different structural parameters were carried out on a wind tunnel test rig.Influence of the fin length,pitch and height on heat transfer and flow resistance characteristic was compared and analyzed,in which both fin length and pitch have a strong influence on factors j and f,while fin height effects slightly.Simultaneously,factor 3j/f was used to evaluate the enhanced heat transfer effect of the 8 kinds of louver fins.Results show that fin length has the most obvious effect in enhancing heat transfer.Figs 6,table 1 and refs 10. |
