摘要: 
本實驗的主體,為中華電信股份有限公司為了擴大網路的服務範圍,在馬路邊裝設的高容量屋外型電信機箱,分為內外兩層,內層是封閉空間,安裝網路設備,為主要的熱源,外層安裝線路設備與散熱裝置。
本實驗探討高容量屋外型電信機箱的有效散熱設計機構,以空氣為冷卻流體進行散熱實驗,並分析高容量屋外機箱之熱傳效益。內裝350W、600W、850W三種定量熱源,交互搭配使用一到三種散熱機構,即:
(1)側邊的熱交換器
(2)頂端的八個排熱風扇
(3)在內機箱上的強制氣冷(熱沉與風扇的組合)

實驗的結果發現(1)平衡溫度會隨環境溫度而改變(2)強制氣冷可提升散熱效率約6.5%~ 20%(3)可以降低機箱內的平衡溫度,以減少電路板的故障率,同時也可以提升服務品質。

The main object of experiment is built for expanding service area in Chunghwa Telecom Company , LTD. It is a metallic box that is on the side of the road used for High Capacity Tele-communication System. It consists of two layers. Inside layer is installed with internet equipment that is the main heat source. Outside layer is installed with subscriber line and cooling equipment.

The experiment is researched for cooling structure of an outside metallic box used for High Capacity Tele-communication System. The process of experiment is used with air for cooling fluid. Then analyses the effect of heat transfer that cooling structure of an outside metallic box used for High Capacity Tele-communication System Inside layer has three fixed heat source that are 350W,600W and 850W. There are 1 ~ 3 cooling structures that are consist of
(1)heat exchanger on the side of the box
(2)eight cooling fans on the top of the box
(3)forced cooling structure( assemble with heat sinks and fans)

The result of experiment find (1)Balance temperature changes and follows the background temperature. (2)It can create 6.5%~20% effect of heat transfer with forced cooling structure (3)it could reduce the balance temperature and fault rate of circuit board. At the same time , it can advance the service quality.
