This research presented the heat resistance characteristics of heat sink which is newly designed through the experiment. For the same volume and base plate of heat sinks, the experiment of heat transfer characteristics was conducted for forced convection of layered type heat sink. The heat transfer and pressure drop characteristics of the layered type heat sink were comparaed for the vsrious kinds of fin pitches, fin heights and heights of heat sink. The results show that thermal resistance is decresed as the height of heat sink increases and the fin height and fin pitch decrease. From the experimental data of layered type heat sink, the correlation equation of Nusselt number was obtained as follows ; <식 참조>
