It has been shown that by increasing the film coefficient "h" by means of forced convection the heat transfer rate of a finned pin can be considerably improved. For an average flow rate of air over the extended surfaces, throughout the investigation the increase in the effectiveness was as much as 4.60 times over the free convection process. However the effectiveness decreases with the increasing root excess temperatures. The heat loss through the insulation was about 1.86 percent, which will not impair the accuracy for engineering applications.
