熱電致冷晶片在烘碗機上的應用
Using Thermoelectric Cooling Module to Dish Dryer System
摘要
本論文係以目前市面上所販售之家庭用烘碗機加以改裝，將其熱源由目前常用的線圈加熱型式改用TEC1—12706熱電致冷晶片的熱面所產生的熱來取代；討論熱電致冷晶片應用在烘碗機上的可行性。 實驗針對使用單顆熱電致冷晶片及兩顆熱電致冷晶片做為其熱源，再輔以橫流風扇進行出風口角度調整，使烘碗機內形成循環的流場，且有均勻的烘乾效果。由實驗數據得知；兩顆的熱電致冷晶片較單顆的熱電致冷晶片並不會有較佳的烘乾效果，如果需要有較佳的烘乾速度應該使用功率較高的熱電致冷晶片。在半封閉的腔體內，橫流風扇出風口角度調整並不能加快烘乾速率，但可以維持腔體內的溫度均勻。熱空氣回收系統可以讓熱空氣再次循環利用，讓腔體內的溫度可以維持在一定範圍，不會因為熱量發散造成溫度持續下降影響烘乾效率。

This thesis indicates those based on the current household dish dryer in the market and modify it. We change its heater from current general circuit heater to thermoelectric cooling module heat surface. We discuss the possibilities to apply thermoelectric cooling module on the dish dryer. This experiment is that we use single TEC1-12706 thermoelectric cooling module and two pieces of thermoelectric cooling modules as heat source, and assist with a cross flow fan as adjustment the direction of air flow out, which makes the dish dryer air flow circulation smoothly, and has well-distributed effect. According to the experiment data, 2 pieces of thermoelectric cooling modules do not have better dryer performance than single thermoelectric cooling module. If it requests better dryer speed, it requires thermoelectric cooling module with higher watt. In half-closed space, adjusting the angle of air flow out of cross flow fan cannot make the dryer speed quicker, but it can maintain the temperature in the space averagely. Hot air recycle system can make hot air to re-use and recycle again which makes the temperature of the space to keep in a certain range. It does not have impact on the dryer efficiency due to heat spreading which causes temperature continuously going down.
