Natural Convective Study Of Heat Transfer from Plate-Finned Heat Sinks
Keywords:
Natural convection, plate fin heat sinkAbstract
Natural convection heat transfer from vertical rectangular plate finned heat sink was experimentally examined. An experimental setup was constructed, 25 sets of vertical rectangular plate finned heat sink were tested in natural convection. The fin height was varied from 5mm to 25mm for 200mm length fin array. The thickness of fin and length of fin was kept constant for all sets of heat sink. The fin spacing was varied from 5.5mm to 17mm.The base to ambient temperature difference was also varied systematically ranging from heat input 10 W to 50 W. The experimental results have shown that the convective heat transfer rate from plate finned heat sink depends on base to ambient temperature difference and geometric parameters. The effects of geometric parameters such as fin height, fin spacing and base to ambient temperature difference were obtained for different heat input
