本實驗團隊將利用脈衝式熱管做為工業產品的應用改良,試圖將熱管的良好散熱與導熱的特性,用於解凍鮮食與肉品的相關應用。目標製作以銅管製成之封閉環路夾入挖直線溝槽之鋁板內,以板體中心為冷端,而其他部分都為熱端時可啟動的水平式脈衝式熱板,解決脈衝式熱管免除了內部之毛細結構之特點但受制於只能用在垂直方向之限制,也改進了水平式脈衝式熱管之水平啟動之問題。
同時設計一個可以經由電腦紀錄資料之冰溶解速率儀器(Ice Melting Rate Measurement Instrument;IMRM),有別於一般市面上之解凍板只是用冰塊做粗略之目視融冰實驗,很不客觀,若有此儀器將可以雙方進行同步測試,比對出各家解凍板之效率高低,將來能夠提供業界來使用。本實驗利用以50%之填充率來進行重複性測試,其溶解速率證明在以重量較輕與體積較小的條件下比市售之解凍板還好。實驗結果在室溫31°C下PHP加入50%填充率溶解直徑3cm高7cm冰柱時間為406秒,0%填充率之溶解時間為507秒,200*280*5(mm)之鋁合金板為445秒,而在儲水槽加入輔助50°C溫水後溶解時間降低至293秒。
關鍵字:脈衝式熱管、解凍板、融冰實驗、溶解速率
The experimental team will use pulsed heat pipes as an application improvement for industrial products, trying to use the heat dissipation and heat transfer characteristics of heat pipes for the application of thawing fresh food and meat. The target is made by a closed loop made of copper pipe sandwiched into the aluminum plate of the straight groove, the center of the plate is the cold end, and the other part is the horizontal pulse type hot plate which can be started at the hot end, and the pulse type is solved.
At the same time, we design an Ice Melting Rate Measurement Instrument (IMRM) that can record data via computer. It is different from the general thaw plate in the market. This instrument will be able to perform simultaneous testing on both sides, comparing the efficiency of each thawing plate, and will be available to the industry in the future. This experiment used a 50% fill rate for repeatability testing, and its dissolution rate proved to be better than the commercially available thawing plate under lighter weight and smaller volume conditions. Experimental results at room temperature 31°C PHP added 50% filling rate dissolved diameter 3cm high 7cm icicle time is 406 seconds, 0% filling rate of dissolution time is 507 seconds, 200 *280*5 (mm) of aluminum alloy plate It was 445 seconds, and the dissolution time was reduced to 293 seconds after the auxiliary water temperature of 50°C was added to the water storage tank.
Keywords:pulsed heat pipe, thawing plate, ice melting experiment, dissolution rate
