The main target of this study is to find and compare the effect of fins design, surface area and air distribution on the heat transfer of the Cross-flow heat exchanger. This study includes Six different models designed using Solid work 2017 program and numerically analyzed using ANSYS 16.1. All finned tubes share similar dimensions with (24, 19 and 21) mm of outer, inner and root diameters respectively. The study clarified non-linear relationship between the increase in surface area, the rate of the heat transfer, the coefficient of the heat transfer and enhancement ratio, taking into consideration the effect of the external shape of the fin and the method of air distribution on the surface of the tubes. Circular fins with a rectangular section showed the best heat transfer rate among all others models, although the increase in surface area of circular fins was not optimal among the other fins.
