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，板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。板式換熱器價格今天小衛給(gei)大家詳細介紹一(yi)下管(guan)(guan)(guan)殼式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)和閉式(shi)(shi)(shi)冷(leng)卻塔有著哪(na)些不同之處(chu)，在現實(shi)使用過程(cheng)中閉式(shi)(shi)(shi)冷(leng)卻塔替代(dai)管(guan)(guan)(guan)殼式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)已(yi)成(cheng)趨一(yi)、封閉式(shi)(shi)(shi)冷(leng)卻塔管(guan)(guan)(guan)殼式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)概念及結構管(guan)(guan)(guan)殼式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)（shell and tube heat exchanger）又稱列管(guan)(guan)(guan)式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)。是以封閉在殼體(ti)中管(guan)(guan)(guan)束的壁(bi)面作為(wei)傳熱(re)(re)(re)面的間壁(bi)式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)。這(zhe)種換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)結構較簡單，操作 ，可(ke)用各種結構材(cai)料（主要是金(jin)屬材(cai)料）制(zhi)造(zao)，能在高管(guan)(guan)(guan)殼式(shi)(shi)(shi)換(huan)(huan)熱(re)(re)(re)器(qi)(qi)(qi)(qi)由殼體(ti)、傳熱(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(deng)部(bu)件組成(cheng)。殼體(ti)多為(wei)圓筒形，內部(bu)裝有管(guan)(guan)(guan)束，管(guan)(guan)(guan)束兩端(duan)固(gu)定在管(guan)(guan)(guan)板上。
