多孔性散熱片之熱交換器分析

本論文主要是在探討散熱檔板、散熱鰭片及多孔性散熱檔板的熱交換的情形。以多孔性性質，來探討熱源及冷源溫度分佈以及散熱檔板和鰭片的溫度分佈情形。這冷卻系統設計的原理是將水柱直接衝擊在熱源處以達到高性能冷卻之效果並探討外界(冷源)處以達到高性能吸熱之效果。散熱檔板以多孔性的性質探討跟一般的散熱檔板之熱源及冷源處的散熱及冷卻之效果。利用STAR-CD 3D軟體分析相關參數對系統的散熱效果。根據分析，可得到在熱源及冷源的熱流在相同或相反方向時，當熱源的熱流速度變化，而冷源的熱流速度維持不變；或是當熱源的熱流速度維持不變，而冷源的熱流速度變化的情況下，散熱鰭片之片數、寬度和高度在一定的數值下熱傳量為最高。並可以把此設計運用在散熱系統之中。

This thesis focused primarily on the heat exchange conditions of heat sinks, fins and porous heat sinks. The effects of porosity on thermal distribution of both heat sinks and fins from heat and cool sources were investigated. The design principle of the cooling system is to directly spout the heat source and optimize the conditions of cool source in order that high cooling performance would be reached. Heat distributions and cooling performances of porous heat sinks were both compared with those of traditional heat sinks from each heat and cool sources. Relevant parameters on the effects of heat distributions in this system were analyzed by the software STAR-CD3D.
