摘要

本研究主要是以實驗方法探討市售不同散熱模組對於單一高性能微電子裝備之移熱能力特性，選擇六種不同構型及材質的鰭片（柱）散熱模組。包括銅材質片狀形散熱鰭柱放射分佈、鋁材質片狀形散熱鰭柱成排分佈、鋁材質圓柱形散熱鰭柱成排分佈、銅材質片狀形散熱鰭柱成排分佈、銅材質片狀形散熱鰭柱放射分佈外加導熱管、銅材質圓柱形散熱鰭柱成排分佈。分析六種散熱模組在自然對流及強制對流狀態下的散熱能力。實驗結果指出，在自然對流下，鋁材質圓柱形散熱鰭柱成排分佈散熱模組的散熱能力最好，在強制對流下，則是銅材質片狀形散熱鰭柱放射分佈外加導熱管的散熱能力最好。

In this study, we investigated the heat transfer capability of different commercial heat sinks for single high-performance micro electronic equipment. Six finned heat sinks, made of various configurations and materials, were selected as test specimens. There were the sheet-shaped copper fins with radiation distribution, the sheet-shaped aluminum finswith row distribution, the circular aluminum pin finswith in-line distribution, the sheet-shaped copper finswith row distribution, the sheet-shaped copper fins with radiation distribution plus heat pipe, the circular copper pin fins with in-linedistribution. The thermal performances of this six heat sinkswere measured experimentally under the free-convection and forced-convection conditions. Through the experiment, it was found that, under free-convection condition, the heat dissipation ability of the circular aluminum pin fins with in-line distributionwas the best. However, the heat transfer ability of the sheet-shaped copper finswith radiation distribution plus heat pipe was the maximum when the forced-convection condition was applied.
