style="text-indent:25px">板式換熱器傳熱效率的樞紐是進步傳熱系數(shù)和對數(shù)均勻溫差。板片加厚，能進步換熱器的承壓能力。該方式應采用逆流布置，使冷介質出換熱器的溫度較高，保證換熱器出口合流后的冷介質溫度能達到設計要求。板換式換熱器的效能是一個綜合經濟效益題目，應通過技術經濟比較后確定。采用對稱型或非對稱型、單流程或多流程板換式換熱器，均可設置換熱器旁通管，但應經具體的熱力計算。在知足換熱器承壓能力的條件下，應盡量選用較小的板片厚度。多流程組合泛起混合流型，均勻傳熱溫差稍低。</p><p style="text-indent:25px">板式換熱器大多是由不銹鋼薄板壓制而成。但是鈍化膜被破壞后將使不銹鋼板片產生均勻的或局部的腐蝕。板式換熱器表現(xiàn)出的腐蝕現(xiàn)象大多是Cl引起的應力腐蝕，不銹鋼雖有極好的耐腐蝕性。常發(fā)生在板片密封槽底部以及有污垢形成后的垢底部位，其主要成因為：不銹鋼板片由機械冷沖壓而成，不可防止地殘存一定量的外表剩余應力，對于不含鉬元素的不銹鋼薄板，外表剩余應力的消除是很困難的。板片組裝后形成了多縫隙結構，相鄰板片波紋頂端相互交叉形成大量觸點。交叉觸點上將存在縫隙，縫隙內介質流動不暢，使縫隙內外存在氧的濃度差，從而引起縫隙腐蝕。當板片表面的污垢嚴重時，介質中的腐蝕元素（ClS等）可能大量附著于污垢，并在垢底縫隙處富集。板式換熱器兩種流體可實現(xiàn)純逆流，一般為順流或逆流方式。</p><div

style="text-indent:25px">防止板式換熱器結垢的措施：1)運行中嚴把水質關，必須對系統(tǒng)中的水和軟化罐中的軟化水進行嚴格的水質化驗，合格后才能注人管網中。2)新的系統(tǒng)投運時，應將換熱器與系統(tǒng)分開，進行一段時間的循環(huán)后，再將換熱器并人系統(tǒng)中．以避免管網中雜質進入換熱器。3)在整個系統(tǒng)中，除污器和過濾器應當進行不定期的清理外，還應當保持管網中的清潔，以防止換熱器堵塞。板式換熱器的選型應根據(jù)換熱場合的實際需要而定。對流量大允許壓降小的情況，應選用阻力小的板型，反之選用阻力大的板型。根據(jù)流體壓力和溫度的情況，確定選擇可拆卸式，還是釬焊式。確定板型時不宜選擇單板面積太小的板片，以免板片數(shù)量過多，板間流速偏小，傳熱系數(shù)過低，對較大的換熱器更應注意這個問題。換熱器又稱熱交換器。河源換熱器品牌哪家好</p><p
