管(guan)(guan)殼式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)(shell and tube heat exchanger)又(you)稱列管(guan)(guan)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)。管(guan)(guan)殼式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)是以封(feng)閉在殼體(ti)(ti)中(zhong)管(guan)(guan)束的(de)壁(bi)(bi)面作(zuo)為(wei)傳熱(re)(re)(re)(re)面的(de)間壁(bi)(bi)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)。這種換(huan)熱(re)(re)(re)(re)器(qi)結構(gou)較簡單，操作(zuo)可(ke)靠，可(ke)用各(ge)種結構(gou)材料(liao)（主(zhu)要是金屬材料(liao)）制(zhi)造，能在高(gao)溫、高(gao)壓下使用，是目前應用廣的(de)類型。管(guan)(guan)殼式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)是怎樣運行的(de)管(guan)(guan)殼式(shi)(shi)換(huan)熱(re)(re)(re)(re)器(qi)由殼體(ti)(ti)、傳熱(re)(re)(re)(re)管(guan)(guan)束、管(guan)(guan)板(ban)、折流板(ban)（擋(dang)板(ban)）和管(guan)(guan)箱(xiang)等(deng)部件組成。殼體(ti)(ti)多為(wei)圓筒(tong)形，內(nei)部裝有管(guan)(guan)束，管(guan)(guan)束兩端固(gu)定在管(guan)(guan)板(ban)上。進行換(huan)熱(re)(re)(re)(re)的(de)冷熱(re)(re)(re)(re)兩種流體(ti)(ti)，一種在管(guan)(guan)內(nei)流動，稱為(wei)管(guan)(guan)程(cheng)流體(ti)(ti)；另(ling)一種在管(guan)(guan)外流動，稱為(wei)殼程(cheng)流體(ti)(ti)。

誤區一、只比較換熱面積好多用戶在詢價時，只向詢價單元提供換熱面積，安徽容積式換熱器哪家好的確不管哪品種型的容積式換熱器，管殼式換熱器面積相同的狀況下，型號差別、結構構成差別、所用材質規格差別、流程組合差別，它們的價錢是不具有可比性的，并且在運用流程中所表示出來的工作功能也會有很大差異。誤區二、拿著某一個廠家的選型單詢價差別的生產廠家，緣于本身的加工才能、實際使用經歷 、引薦習氣等要素，容積式換熱器哪家好往往對(dui)用戶的(de)某一運(yun)用要求及(ji)工(gong)藝工(gong)況(kuang)并不(bu)明白(bai)得十分透徹，計劃選(xuan)型會出(chu)現(xian)偏(pian)頗。
