摘要

隨著電子產品性能提升及微小化，使得產品元件發熱密度快速提升，因此如何將高密集熱量，快速擴散至散熱座上散熱是為重要關鍵。本研究利用杜拉鋁合金製作蒸氣腔體，期能對於個人電腦之有效散熱方式，提供一設計上研究參考。並運用熱管的原理，在低成本及最高安全考量下，運用於一般傳統鋁質散熱器上，以提升其散熱效率，並藉由實驗方式，找出最佳工作流體及填充量與蒸氣腔體內高度，以因應未來超高溫電子元件的散熱需求。
本文針對蒸氣腔體(內高8mm，底厚2mm)及(內高5mm ，底厚5mm)兩種不同內高度及底厚，工作液體填充量，填充液體的種類不同及固定風量對散熱器性能之影響進行實驗研究與比較。由實驗數據顯示填充量分別為54.34%及52.17%時，其散熱效果最佳，工作液體使用甲醇比使用水的散熱效果更好。而蒸氣腔體(內高5mm ，底厚5mm)散熱效果更優於(內高8mm，底厚2mm)。

Following the functional enhancement and miniaturization of electronic product, the heat density of the product component increases rapidly. Therefore how to diffuse the highly concentrated heat energy to the heat sink for heat dissipation is the important key. This research utilizes the Dura aluminum alloy to produce the vapor chamber hoping that it can provide a research reference in the design of effective heat dissipation method in personal computer. In addition, the principle of tube is utilized that is applied in general traditional aluminum heat sink under the consideration of low cost and high safety so as to enhance its heat dissipation efficiency. In addition, based on experiment method, the best working fluid and filling volume and the height inside the vapor chamber can be found so as to cope with the heat dissipation requirement of super high temperature electronic component in the future.
Aiming at the different interior height and bottom thickness of the
vapor chamber (internal height 8mm, bottom thickness 2mm) and (internal height 5mm, bottom height 5mm), working fluid filling volume, effect on the heat sink function of different type of filling liquid and fixed wind volume, this essay conducts experiment research and comparison. From the experiment data, it shows that when the heat dissipation effect is the best when the filling volume is 54.34% and 52.17% respectively. Also, when the working fluid adopts methanol, the heat dissipation result is better than water. In addition, the heat dissipation result of the vapor chamber (with internal height of 5mm and bottom thickness of 5mm) is better than the vapor chamber (with internal height of 8mm and bottom thickness of 2mm).
