對于換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)，很(hen)多(duo)(duo)人都是非常(chang)熟悉的，換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)的種類并(bing)不是單一的，管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)就是一種比較常(chang)見的換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)，很(hen)多(duo)(duo)人都想知道管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)是如(ru)何工作(zuo)的，今天小編就為大家簡單的介紹一下管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)的工作(zuo)原理(li)(li)和結構(gou)。管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)有多(duo)(duo)層(ceng)導熱(re)(re)特性(xing)良好的材料疊合而成(cheng)工作(zuo)原理(li)(li)和熱(re)(re)水(shui)器(qi)(qi)類似，熱(re)(re)水(shui)器(qi)(qi)是由燃(ran)氣燃(ran)燒時產生熱(re)(re)而換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)是發熱(re)(re)的介質(zhi)不是明(ming)火(huo)，換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)內部有兩路管(guan)(guan)道回路。管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)的工作(zuo)原理(li)(li)是什么一個(ge)是熱(re)(re)源(yuan)另一個(ge)是被(bei)(bei)加(jia)熱(re)(re)源(yuan)熱(re)(re)源(yuan)就像熱(re)(re)水(shui)器(qi)(qi)燃(ran)燒時的火(huo)焰如(ru)熱(re)(re)水(shui)或蒸(zheng)汽等(deng)。被(bei)(bei)加(jia)熱(re)(re)源(yuan)就像熱(re)(re)水(shui)器(qi)(qi)里被(bei)(bei)加(jia)熱(re)(re)的水(shui)。還有熱(re)(re)源(yuan)回路中換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)的熱(re)(re)源(yuan)進口(kou)前有一個(ge)調節閥通(tong)過改變這個(ge)閥門的開度(du)就可以調節被(bei)(bei)加(jia)熱(re)(re)源(yuan)的溫度(du)。管(guan)(guan)殼(ke)式(shi)(shi)換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)(qi)由殼(ke)體、傳熱(re)(re)管(guan)(guan)束、管(guan)(guan)板(ban)、折流板(ban)（擋板(ban)）和管(guan)(guan)箱等(deng)部件組成(cheng)。

管殼式換熱器其壽命設計的管殼式換熱器約為30年左右，為4年左右的檢修期，如果換熱器泄漏，生活熱水設備價格可能是管和管道泄漏引起的泄漏或破裂的管板之間，壁管方法可在短時間內恢復工作業績，讓7%堵冠宇管換熱器。根據橡膠球清洗裝置的需要，可進行定期的機械清洗。供應生活熱水設備這個方(fang)(fang)法很(hen)簡(jian)單(dan)。 板(ban)(ban)(ban)(ban)式(shi)換(huan)熱器(qi)(qi)(qi)(qi)的(de)(de)維(wei)護方(fang)(fang)法：專業板(ban)(ban)(ban)(ban)式(shi)換(huan)熱器(qi)(qi)(qi)(qi)具(ju)有體積小、重量輕(qing)等特點，維(wei)修(xiu)方(fang)(fang)便，不需要(yao)(yao)設置(zhi)吊(diao)裝(zhuang)設施，安裝(zhuang)面積少。板(ban)(ban)(ban)(ban)式(shi)換(huan)熱器(qi)(qi)(qi)(qi)的(de)(de)手動維(wei)護包(bao)括(kuo)整個機(ji)器(qi)(qi)(qi)(qi)的(de)(de)折疊，用噴水槍和(he)毛刷(shua)清洗板(ban)(ban)(ban)(ban)和(he)墊片(pian)，必要(yao)(yao)時檢(jian)查板(ban)(ban)(ban)(ban)和(he)墊片(pian)，必要(yao)(yao)時更換(huan)板(ban)(ban)(ban)(ban)和(he)墊片(pian)。管殼式(shi)換(huan)熱器(qi)(qi)(qi)(qi)和(he)板(ban)(ban)(ban)(ban)式(shi)換(huan)熱器(qi)(qi)(qi)(qi)如何(he)維(wei)修(xiu)板(ban)(ban)(ban)(ban)式(shi)換(huan)熱器(qi)(qi)(qi)(qi)通(tong)常每年需要(yao)(yao)清洗一(yi)次(ci)，無論(lun)是否實(shi)用，都要(yao)(yao)做(zuo)。
