電熱為家庭普遍使用的加熱方式,舉凡熱水器、暖氣機及照明系統等,而其中以電阻式加熱為最常見的方法。但電阻式加熱雖方便,卻有著轉換效率較低,以及瞬間功率高及危險的問題。因此希望藉由非接觸式的感應加熱來做為新的熱量來源,藉此提升家電用品的安全性與效率,達成環境友善與節能的目標。
本實驗藉由零點電壓切換(Zero-Voltage Switching, 簡稱ZVS)系統之高週波進行感應加熱,讓磁性材料上出現感應渦電流,產生電流熱效應後賦予金屬材料高效率並快速的升溫,再通過水流以達到對水加熱之效果的熱水器雛形,以及利用風力帶走感應加熱後的熱量,藉此達到暖房效果的暖氣機等應用。由於ZVS產生交流磁場的過程可減少硬切換損耗,因此可以延長ZVS的壽命以及增加其效率等優點。本實驗成功利用更低功率以達到電加熱器的升溫標準,驗證了感應加熱為一安全且有效率的發熱方式,可以做為下一代新的加熱方式。
The resistive heating is a most commonly used heating method, such as central heating, water heating, drying machine and hair dryer. However, the resistive heating has a low conversion efficiency and requires a high instantaneous power, so it is costly with safety issue. Induction heating is now widely used in many aspects of engineering whereas it remains challenge for household appliances. This work, for the first time, employs eddy current driven heating with zero-voltage switching as heating elements. Selection of in-duction and geometry of ferromagnetic materials is important and is highly related to heating rate and input-power. An inductive element is then fabricated to function as water heater/or heat sources for others, such as machine dryer and central heating system.
