"本計畫擬開發可針對不同體積之立體模型進行三維分析，由於此研究之發展原理為利用不同容積之三維幾何界面特徵關係，於不需網格化之前處理程序下，直接分析此雙重容積之物理量，因此將其定名為『雙容積界面法』，期望於有限元素法、有限容積法及有限差分法及其他數值方法外，提供能源工程設計人員另一種全新的計算方法。其次，計畫之進一步應用研究，則將此新開發的計算方法，導入高功率LED照明之散熱分析，預期將可應用於發光二極體照明之複合散熱材料、多重幾何散熱模組之三維熱傳分析。此外，計畫中亦將納入實驗驗證，藉由LED散熱模組溫度量測及熱傳率估算，評估雙容積界面法之準確性。經由計畫之研發，預期將能提升高功率LED晶片引起之高溫的散熱效能，進而達到節約能源之效益。再者，此一創新的計算方法，在應用方面除了上述LED散熱模組之三維能源問題分析之外，亦適用於冷凍空調、熱交換器、電子元件冷卻與其他複合材料之能源問題。"
"The present research in order to develop and carry on three-dimension analysis to the geometric model of different volume. Because the development principle of the present research, in order to utilize the geometric interface characteristic relation of three-dimension of different volume, will analyze the physical quantity of this double volume directly under the processing procedure under meshless, And give the name of the methods is ""Double volume Interface Method"" of naming it, one hope expect in the finite element method, finite volume method, finite different method and other numerical methods, offer another kind of brand-new computing technology to a energy project designer. Secondly, the further application study of the proposal, this new computing technology developed into the heat-dissipating analysis of the high power LED lighting, It is expected that can apply complex heat-dissipating material, multiple geometric of three-dimension analysis of the heat transfer module. In addition, will also include in the plan in the experiment research to prove, by the temperature measure and predict the heat transfer rate will be examined by heat-dissipating module of LED lighting. And comparison the accuracy to the Double volume interface method. Through the analysis of the proposal, expect to be able to improve the heat dissipation efficiency under the heat generation of high brightness, high power LED, and then improve the luminance and energy saving. Moreover, this innovation computing technology, besides three-dimensional energy case study of the above-mentioned heat-dissipating mould group LED in application, the energy questions of cooling as to refrigeration and air condition, heat exchanger, 3C electronic element and other composite material, also benefit to some extent."
