摘要
本文以空气为介质，对四组百页窗式翅片通道的传热特性和流动阻力进行了试验研究。四组试验件的几何尺寸相同，只是翅片上百页窗的开窗段不同，分别是３ｍｍ、 ６．５ ｍｍ、前３ｍｍ后 ６．５ ｍｍ及各组开窗段间距交替为 ３ ｍｍ与 ６．５ ｍｍ。传热试验得出的四种试验通道 Ｎｕ～ Ｒｅ关系相同，而阻力则以开窗段间距 ３ ｍｍ的为最低。
The heat transfer and flow friction characteristics of four kinds of louvered fin channels. Were investigated experimentally in this paper. The geometric structures, except for the louver pitches, of these four louvered fin channels are the same and the air is as the testing medium in this experiment. The test result shows that: these four kinds of louvered fins' Nu-Re relationship is basically similar with each other, While the channel with the minimum pressure drop is the one whose louver pitch is 3 mm.
