椭圆铝翅钢管具有良好的传热和流阻性能

以及足够的结构强度

可用于空冷发电机组的空气冷却器及大中型变压器。

Abstract

In order to precisely master the title properties of air coolers using elliptic steel tubes with rolled alumimum fins as heat exchanger

detection and test of them have been carried out

and the wilson graphical method was applied to separate the heat transfer coefficients on both sides of the said exchanger. The results show

the elliptic steel tubes with rolled aluminum fins have good heat transfer and flow resistance properties

as well as sufficient structural strength

being suitable for air coolers used at power plants in arid areas

and air coolers used on large and medium power Transformers.
