複合材料鍋具的熱傳性能分析

Abstract

隨著科技文明的發展，能源議題逐漸受到重視，其中如何提升能源的使用效率和減少成本原料的使用，都是現在需要挑戰與創造。因此現今在家庭生活用品上，幾乎都朝著這方向邁進。而廚房用具中的鍋具，更是在家庭中將能源使用在食品上的重要媒介。如何在鍋具上提升能源的使用效率和減少成本原料的使用便是本研究的主要課題。 本研究進行數值模擬前，為了驗證溫度分布的均勻性對能源效率的使用影響，分別對三種不同加熱源電晶爐、卡式爐及電爐搭配不銹鋼複合銅之鍋具進行煮水實驗的操作。得到溫度分布均勻性較好的，較能有效率提升水溫。因此在數值模擬的研究上，嘗試找到用多少比例的鋁取代銅且能盡量達到溫度分布均勻性較好的組合，讓不銹鋼複合銅鋁之鍋具能盡量達到溫度分布的均勻也能降低成本的花費。 在研究結果方面，當不銹鋼複合銅鋁之鍋具在某種組合的條件下，能夠找到其溫度分布的均勻性能盡量貼近不銹鋼複合銅之鍋具的均勻性，且其平均偏差的差值小於約1以內時，最多能將約36%的銅用鋁取代；約節省33%的成本。

With the development of civilization and technology, increasing attention has been given to energy issues, how to improve energy efficiency and reduce the cost of materials are need to be challenged and created. The cookware of kitchen appliances, is the important medium for energy used to food at home. Therefore, how to improve energy efficiency and reduce the cost of materials is the main subject of this research. In order to verify the efficiency of the energy be used on the uniformly temperature distribution before the numerical simulation. Respectively, using the stainless steel cookware composite of the copper in the experiments to boil water for three different heating sources, electric furnace, portable gas stove and furnace. Obtain a result, more uniformly of the temperature distribution is more efficiently of the water boiling. So, the study of numerical simulation is trying to find a combination of stainless steel, copper and aluminum, which can replaced copper by the maximum of aluminum. Also, achieve a uniformly temperature distribution and less cost. In the study, we can find a thirty-six percent of copper replaced by aluminum in a combination, and the performance of the temperature distribution is less than one degree with basis line. And totally, cut down the thirty-three percent of the cost, is the optimum.
