"由於空間加熱器為高耗能的發熱元件，因此對於能源的應用效率也相對重要，本計畫擬設計一組高效率之空間加熱器，其構成元件包含加熱體、對流礦物熱油及導熱板，計畫中將選用不同之導熱材料進行分析。此合成區域及複合材料於計畫開始之建模過程，先以 Lpalace equation 及 Poisson equation 兩項橢圓形偏微分方程式表示之，邊界條件則為第三類之熱對流邊界條件。分析過程，首先以格點對應法(Point matching methods)進行分析，其後再進一步以截斷級數法(Series truncation methods)驗證其精度，並比較上述兩種方式對於溫度及熱通量之差異。此外，不同材料與尺寸之加熱體、導熱板及熱油對於熱能效率之影響，亦將於計畫中分析探討，預計將對於空間加熱器之能源消耗量與材料規劃需求都能大幅降低其成本。"
"The consumption of the energy of the space heater are highly cost, the application efficiency to the energy is relatively important, this proposal plans to design a group of high-efficiency space heaters, it forms the component and includes heating unit, hot oil of convection heat transfer and heat dissipation board, plan the lieutenant general and select different heat conduction materials for use to analyze. This formates modeling course begun in the plan in the complex domain, are expresses in the Lpalace equation and Poisson equation first, and the boundary condition is the third kinds of boundary condition of Robin conditions. Analytic process, the Point matching methods will be first calculate methods, and check the precision by using Series truncation methods . Furthermore, the proposal will comparison the precision of both the Point matching methods and Series truncation methods. In addition, different materials and heating unit, heat dissipation board and hot oil influence in the efficiency of heat energy with the different dimensions of heating element , will also analyze and research into in the poposal, it is estimated that can reduce their cost to consume the demand steps by a wide margin to energy consumption and material of the space heater."
