| dc.description.abstract | 筆記型電腦的散熱技術是一直需要不斷的開發與研究的。隨著電腦內部散熱問題的日益嚴重，除了尋求更創新的散熱方案之外，應確實修正原有的散熱設計缺失，並更進一步了解電腦系統內部的散熱情況與行為模式，從而分析與改善電腦系統散熱機制使其達到理想的操作溫度，為目前筆記型電腦最為主要的工作。
本論文著重在目前較為新穎的NetBook散熱部分，NetBook主要特點為低功耗、小尺寸及輕薄，因NetBook消耗瓦數較少的特性，本文嘗試使用無風扇的自然對流方式進行散熱，希望能降低噪音及減少耗能。測試市面現有機種後發現如果使用傳統自然對流散熱方式將溫度傳導到機殼，往往會造成機殼過熱影響使用者觀感，因而設計改良型自然對流散熱系統，此一系統使用熱管( heat pipe )將主要發熱原件所產生的熱傳導至系統後方，再經由後方的散熱孔與外界空氣進行熱交換達到散熱的目的，並且須配合在底座內側貼附一良好熱導體，藉以避免塑膠底座熱傳導效率較差所導致的局部過熱現象。接著以等效模組( dummy box )進行測試驗證，確認此改良型自然對流散熱系統具備可行性，可應用在低瓦數筆記型電腦。

| dc.description.abstract | Notebook’’s cooling technology has been needing a continuous development and research. Because the computer inner part cooling technology problem of serious day by day, have to look for to more creatively cooling technology project. Really revising is original of spread heat design imperfection. Understand passionate condition and behavior pattern in the cooling technology for computer system inner part further. Analyze computer system to spread with improvement hot mechanism to make it reach ideal operation temperature. It is currently the mainest work of notebook.
This thesis emphasizes in NetBook to spread hot part. The NetBook main distinguishing feature consumes for low achievement, baby size and frivolity. Because NetBook consumes tile count less of characteristic, this text tries the natural convection method of using the calm to carry on spreading heat. We hope to reduce noise and decrease to consume an ability. After testing an existing model, if we use traditional natural convection to spread a hot way and conduct the temperature to the machine hull. It will cause the machine hull lead hot influence user’’s impressions. As a result the design modified version natural convection spreads hot system. This system’’s using a hot pipe will mainly have fever the heat that the component produces to conduct to the rear of the system. It spread through the rear again hot hole and outside air to carry on hot commutation to reach to spread a hot purpose. It must match with in the base seamy side to post to attach one good hot conductor. Avoid worse part caused of plastic base heat conduction efficiency leading a hot phenomenon. After test by waiting for effect module to carry on an identification. It confirm this modified version natural convection to spread hot system to have a feasibility. This cooling technology can apply a notebook at low watt.
