封閉式冷卻塔和管殼式換熱器同屬于水換熱冷卻裝置，有著本質的區別。閉式冷卻塔除了熱交換的過程，可以直接蒸發吸熱，半容積式換熱器將熱量排走，而管殼式換熱器只能換熱，使用過程中還需要另外的設備進行排熱。半容積式換熱器哪家好今天(tian)小衛給大家詳細(xi)介(jie)紹一下管(guan)(guan)(guan)殼(ke)(ke)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器和閉式(shi)(shi)冷卻塔有(you)著哪些不同之處(chu)，在(zai)(zai)現實使用過程中閉式(shi)(shi)冷卻塔替(ti)代(dai)管(guan)(guan)(guan)殼(ke)(ke)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器已成(cheng)趨一、封閉式(shi)(shi)冷卻塔管(guan)(guan)(guan)殼(ke)(ke)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器概念及結構(gou)(gou)管(guan)(guan)(guan)殼(ke)(ke)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器（shell and tube heat exchanger）又稱列管(guan)(guan)(guan)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器。是(shi)以封閉在(zai)(zai)殼(ke)(ke)體中管(guan)(guan)(guan)束的(de)壁面作為傳熱(re)(re)(re)(re)面的(de)間壁式(shi)(shi)換(huan)熱(re)(re)(re)(re)器。這種(zhong)換(huan)熱(re)(re)(re)(re)器結構(gou)(gou)較簡單(dan)，操作 ，可用各種(zhong)結構(gou)(gou)材料(liao)（主要是(shi)金(jin)屬材料(liao)）制造，能在(zai)(zai)高管(guan)(guan)(guan)殼(ke)(ke)式(shi)(shi)換(huan)熱(re)(re)(re)(re)器由殼(ke)(ke)體、傳熱(re)(re)(re)(re)管(guan)(guan)(guan)束、管(guan)(guan)(guan)板、折流板（擋板）和管(guan)(guan)(guan)箱等部件組成(cheng)。殼(ke)(ke)體多為圓筒形，內部裝(zhuang)有(you)管(guan)(guan)(guan)束，管(guan)(guan)(guan)束兩端固定(ding)在(zai)(zai)管(guan)(guan)(guan)板上。
