4 heating zones on barrel , all with air - cooling . each zone with multiple rows of copper fins for high cooling efficiency , coupled with oversized cooling fans mounted at the rear of the extruder barrel . large wattage on heaters coupled with the efficient cooling system ensures very fast heating and cooling of each zone 機筒上有4個加熱區域,都帶有空氣冷卻裝置;每個區域含附帶大冷卻風扇的多排銅葉片可獲得高冷卻效果,高功率的加熱模塊同有效的冷卻系統相結合可以確保每個區域的快速加熱和冷卻。

It has issued residential buildings energy design standard for heating zone hot summer and cool winter zone and hot summer and warm winter zone . for heating zone , the method of effective thermal transmittance based steady heat transfer is used for the energy consume calculation , for hot summer and cool winter zone and hot summer and warm winter zone , the method based dynamic heat transfer must be used for the energy consume calculation 對居住建筑,我國已頒布了包括采暖地區、夏熱冬冷地區、夏熱冬暖地區三個節能設計標準,對北方寒冷地區,用建立在穩態傳熱基礎上的有效傳熱系數法進行能耗計算;對夏熱冬冷地區、夏熱冬暖地區,圍護結構受室外動態溫度和太陽輻射熱的綜合作用,明確應采用動態方法計算圍護結構傳熱。

We adopt new production process of cold ends , so our sic heating elements have excellent specific rate of heat zone resistance and cold end resistance , saving energy , long life , avoiding over - temperature of cold ends to damage the furnace body . the commercial name of our sic heating elements is songshan silca heating elements 我們的碳化硅電熱元件采用新的冷端部生產工藝,具有優良的熱冷端電阻比,節能、壽命長,同時避免了因冷端部溫度過高對爐體造成的損害。

Because of the large stuff of silicon , complex structure of furnace and expensive cost , computer simulation is a best way to optimize design . in order to study the new heat system , we have calculated the heat zone of 200mm solar cell czsi growth 由于拉晶過程中投料量較大,爐體結構復雜、造價昂貴,所以計算機數值模擬對于優化單晶爐設計是一種重要的工具。本論文用有限元方法對改造后單晶爐的適合的熱場進行了數值模擬。

Selective heating zone ( 8 , 10 , 12zones ) allow wide variation of profile settings 選擇性的加熱段( 8 、 10和12溫區)為外形設置的變化提供很大空間
