碩士 === 中原大學 === 機械工程研究所 === 93 === ABSTRACT
The main purpose of this study is to research the heat transfer of hot spot for air impingement flow on a heat sink. The dimension of heat sink and Reynolds number are the main parameters affecting the cooling efficiency. In this study, the heat sink is square pin-fin and a 9×9 pin-fin array. The dimension of heat sink base is 70mm×70mm×3mm, and a fin width is 4, 5, and 6 mm, height is 30, 40, and 50 mm. The range of Reynolds number is 5000~30000, and the dimension of hot spot is 30mm×30mm, and the power is 30W. The PHOENICS software CFD package is used for calculating the temperature field and the pressure of heat sink channel.
After the model had simulation and analysis, we can find three better characteristic conditions for cooling efficiency: (1) Reynolds number is 30000. (2) heat sink width is 6mm. (3) heat sink height is 50mm.
