碩士 / 國立交通大學 / 機械工程系所 / 101 / In order to enhance the heat transfer rate of heat sink plate fin, this study made a brand new design to existing heat sink plate fin by introducing the concept of “partial bypass”. The basic idea is to introduce bypass cold stream which bypasses the front part of the plate fin and mixes with the hot stream across the front part of the plate fin, and the mixed stream flows through the rear part of the plate fin. Through this concept, plate fin area is reduced but lowered the pressure drop of forced convection. The concept can be implemented with either maintaining the same total flowrate, heat transfer rate but accompanies with a much lower pressure drop or it can be applied with the same pumping power but accompanies with a much higher heat transfer rate.
