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.
