摘要

以制冷换热器常用的矩表平肋片管作为比较对象，对四种不同片型的肋片管在吸风式直流风洞进行了空气外掠单排肋片管的对比性实验研究，得到了具有实用价值的结论。

Abstract

In this paper

the comparative experimental research that air flows through theout-surface of a single row finned tubes is done in a drawing wind tunnel and the three differnetshapes of rectangluar finned tubes are compared with a plain finned tube that is usually used in therefrigerant heat exchanger

the useful results are obtained. The results show that

in the range ofwind velocity flowing through the marrowest area

W_(max)=2.5m/s to 8.5m/s

the average convec-tion heat transfer coefficient of the two-side V-groove finned tube is higher than that of rectangluarplain finned tube

It is a new type finned tube that has good heat transfer performance and it isworth poplarlzing.
