台灣的散熱模組產業一直是世界最重要的設計製造基地，如果要持續保持這樣的優勢，比其他國家更領先進一步的了解可以解決高熱通量元件的兩相流變化傳熱元件的操作性能是非常重要的。其中結合熱管與熱沉的散熱模組設計，具有下列三項優點：因為利用熱管內部工作流體液/氣兩相變化高熱容量的特性，使散熱模組可在很小的溫度梯度下散逸大量的熱流，所表現的熱性能佳，此為其優點之一。在工作流體的熱傳遞路徑上，可分別利用浮力及重力或毛細力來當作氣體與液體的驅動力，不需要任何流體機械的幫助，例如幫浦，所以散熱模組本身具有高可靠度，此為其優點之二。散熱模組中的熱管可以是數根可彎曲性串/並聯的，所以具有高擴展性，此為其優點之三。因為嵌入式熱管熱沉散熱模組具有上述眾多優點，是兼顧考量成本及熱性能的散熱模組，可加以應用改善目前產業中之急需要高速散熱的系統部分，諸如個人電腦的散熱系統、筆記型電腦散熱、伺服器散熱系統、高功率LED 照明等等。本計畫主要研究目的之一為利用熱性能實驗的方式探討熱管結合熱沉散熱模組的性能，並建立實驗控制參數分析結果資料庫。本計畫主要研究目的之二為以熱阻分析建構熱管結合熱沉散熱模組之熱阻模式，找出其操作性能極限，並輔以數值分析方法的驗證，期能迅速定義嵌入式熱管熱沉散熱模組的熱性能。本計畫主要研究目的之三為使用Visual Basic 程式撰寫一套視窗軟體，期能在數秒之內精確計算嵌入式熱管熱沉散熱模組的熱性能。因此，本計劃在學術方面上及工程實際應用上，皆具有相當的研究價值。Taiwan is the most important design and manufacture base for the thermal module industry in the world. It must be understand the two-phase flow device solving high heat flux heat source in order to maintain the superiority than other countries. Upon the idea we design a embedded heat pipe heat sink thermal module and investigate its performance and characteristics. The three advantages of this system are concluded below: 1. Utilizing the high heat capacity with very small temperature gradient by latent heat between liquid-gas phases and good thermal performance of heat pipe, so it can reduce the thermal resistance of thermal module. And the thermal performance is good. 2. The flow in the system is driven by buoyancy and capillary force. These two driving forces are self-induced, so flow-driven pump component is not necessary in this system. Its reliability is high. 3. The main components of heat pipes can be much and bending combination each other. Therefore the arrangement of the component is much flexible. Therefore, with the above pros, the embedded heat pipe heat sink thermal module is the most potential system with low cost and good thermal performance. The first main purpose of the present research is to utilize the thermal performance experiment to analyze the thermal performance of embedded heat pipe heat sink thermal module. The second main purpose of the present research is to utilize thermal resistance analysis with experimental to derive the correlation of the thermal performance of embedded heat pipe heat sink thermal module through the proof of numerical method. The third main purpose of the present research is to build window software by visual basic program. It can calculate quickly and accurately the thermal performance of embedded heat pipe heat sink thermal module in several seconds. Therefore, the present research is essentially valuable in science and engineering applications.
