家(jia)用(yong)熱(re)交(jiao)換(huan)器解決了(le)(le)集(ji)體供(gong)暖家(jia)庭和冬天用(yong)熱(re)水(shui)(shui)的(de)(de)難(nan)題。它的(de)(de)工作原理跟(gen)集(ji)體供(gong)熱(re)的(de)(de)熱(re)交(jiao)換(huan)器原理相(xiang)同。只是大(da)(da)小(xiao)和樣式(shi)(shi)不同而(er)已。可(ke)分為(wei)鑄鐵(tie)式(shi)(shi)，筒(tong)式(shi)(shi)，鋼制式(shi)(shi)，儲水(shui)(shui)式(shi)(shi)，板式(shi)(shi)。效(xiao)(xiao)果(guo)都(dou)不錯。鑄鐵(tie)式(shi)(shi)熱(re)交(jiao)換(huan)器 的(de)(de)體積(ji)大(da)(da)，重量重。但是里(li)(li)面(mian)的(de)(de)銅(tong)(tong)管(guan)(guan)買(mai)之前可(ke)以(yi)打(da)開檢查一下，不容易被商家(jia)坑騙，而(er)且(qie)用(yong)過幾(ji)年銅(tong)(tong)管(guan)(guan)壞(huai)了(le)(le)還(huan)可(ke)以(yi)更(geng)換(huan)。筒(tong)式(shi)(shi)的(de)(de)體積(ji)小(xiao)，交(jiao)換(huan)效(xiao)(xiao)率高。但用(yong)戶不能(neng)(neng)查看里(li)(li)面(mian)銅(tong)(tong)管(guan)(guan)的(de)(de)長(chang)(chang)度，也(ye)不能(neng)(neng)更(geng)換(huan)銅(tong)(tong)管(guan)(guan)，而(er)且(qie)還(huan)不太(tai)美(mei)觀(guan)。鋼制式(shi)(shi)鋼制式(shi)(shi)體積(ji)有(you)(you)大(da)(da)有(you)(you)小(xiao)。用(yong)戶也(ye)不能(neng)(neng)查看里(li)(li)面(mian)銅(tong)(tong)管(guan)(guan)的(de)(de)長(chang)(chang)度，而(er)且(qie)不能(neng)(neng)更(geng)換(huan)銅(tong)(tong)管(guan)(guan)。但是比較美(mei)觀(guan)。板式(shi)(shi)板式(shi)(shi)，體積(ji)很小(xiao)，重量很小(xiao)。熱(re)交(jiao)換(huan)效(xiao)(xiao)率很高。里(li)(li)面(mian)無銅(tong)(tong)管(guan)(guan)。熱(re)交(jiao)換(huan)能(neng)(neng)力(li)跟(gen)層數有(you)(you)關。層數看得(de)(de)見，摸得(de)(de)著。水(shui)(shui)垢(gou)以(yi)上各種交(jiao)換(huan)器在(zai)使用(yong)過程中都(dou)會產生(sheng)水(shui)(shui)垢(gou)。用(yong)了(le)(le)幾(ji)年后會出(chu)現水(shui)(shui)流小(xiao)，出(chu)水(shui)(shui)不是太(tai)熱(re)等情況。但在(zai)石家(jia)莊等地(di)也(ye)出(chu)現了(le)(le)專業除(chu)垢(gou)的(de)(de)公司。通過專業除(chu)垢(gou)后也(ye)能(neng)(neng)跟(gen)新的(de)(de)一樣。

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。板式換熱器哪家好今天小衛給大家詳細介(jie)紹一下管(guan)(guan)(guan)殼(ke)(ke)(ke)(ke)(ke)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)和閉式(shi)(shi)冷卻(que)塔(ta)(ta)有(you)著哪些不同之(zhi)處，在(zai)現(xian)實使(shi)用(yong)過程中閉式(shi)(shi)冷卻(que)塔(ta)(ta)替代管(guan)(guan)(guan)殼(ke)(ke)(ke)(ke)(ke)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)已(yi)成趨一、封(feng)閉式(shi)(shi)冷卻(que)塔(ta)(ta)管(guan)(guan)(guan)殼(ke)(ke)(ke)(ke)(ke)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)概念及結構(gou)(gou)(gou)管(guan)(guan)(guan)殼(ke)(ke)(ke)(ke)(ke)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)（shell and tube heat exchanger）又稱列管(guan)(guan)(guan)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)。是以封(feng)閉在(zai)殼(ke)(ke)(ke)(ke)(ke)體(ti)中管(guan)(guan)(guan)束(shu)(shu)(shu)的(de)(de)壁面作為傳(chuan)熱(re)(re)面的(de)(de)間壁式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)。這種(zhong)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)結構(gou)(gou)(gou)較簡單(dan)，操(cao)作 ，可用(yong)各(ge)種(zhong)結構(gou)(gou)(gou)材料(liao)(liao)（主要(yao)是金(jin)屬材料(liao)(liao)）制(zhi)造，能在(zai)高管(guan)(guan)(guan)殼(ke)(ke)(ke)(ke)(ke)式(shi)(shi)換(huan)(huan)(huan)熱(re)(re)器(qi)(qi)由殼(ke)(ke)(ke)(ke)(ke)體(ti)、傳(chuan)熱(re)(re)管(guan)(guan)(guan)束(shu)(shu)(shu)、管(guan)(guan)(guan)板、折流板（擋(dang)板）和管(guan)(guan)(guan)箱(xiang)等部件組成。殼(ke)(ke)(ke)(ke)(ke)體(ti)多為圓筒形，內(nei)部裝有(you)管(guan)(guan)(guan)束(shu)(shu)(shu)，管(guan)(guan)(guan)束(shu)(shu)(shu)兩端固定在(zai)管(guan)(guan)(guan)板上(shang)。
