PHE可(ke)拆板式(shi)換(huan)熱器流(liu)程演示圖：

　　● 高效節能：其換熱(re)(re)系數(shu)在3000～4500kcal/ m2.℃·h，比管殼(ke)式換熱(re)(re)器的(de)熱(re)(re)效率(lv)高3~5倍。

　　●   結構緊(jin)湊：板(ban)式換熱(re)器板(ban)片緊(jin)密(mi)排列，與其他換熱(re)器類型相比，板(ban)式換熱(re)器的(de)占地面(mian)積(ji)和(he)占用空間較少，面(mian)積(ji)相同換熱(re)量的(de)板(ban)式換熱(re)器僅(jin)為管(guan)殼式換熱(re)器的(de)1/5。

　　● 容(rong)易清洗拆裝(zhuang)方(fang)(fang)便：板(ban)(ban)式換熱(re)器靠(kao)夾(jia)緊螺栓將(jiang)夾(jia)固板(ban)(ban)板(ban)(ban)片夾(jia)緊，因此拆裝(zhuang)方(fang)(fang)便，隨(sui)時(shi)可以打(da)開清洗，同時(shi)由(you)于板(ban)(ban)面光潔，湍(tuan)流(liu)程度高，不易結(jie)垢。

　　● 使(shi)用(yong)壽命(ming)長：板式(shi)換熱器采用(yong)不銹鋼板片(pian)壓制，可(ke)耐各種腐蝕介質(zhi)，膠墊可(ke)隨(sui)意更換，并可(ke)方便在、拆裝(zhuang)檢修。

　　● 適(shi)應性強：板式換熱器板片為獨立(li)元件，可按要求隨意增減流(liu)程(cheng)，形式多樣;幾乎適(shi)用于(yu)所(suo)有領域的加熱、冷卻(que)、蒸發(fa)、冷凝、保溫、殺菌過程(cheng)。

　　● 不串液：板式換熱器密封槽設置泄液液道，各(ge)種介質不會串通，即使出(chu)現泄露，介質總是(shi)向(xiang)外排出(chu)。

　　●   能(neng)實現純逆流換熱：充分(fen)利用兩種流體的(de)溫(wen)差，熱回(hui)收(shou)率高(gao)達95%以上，處理微小溫(wen)差的(de)能(neng)力最強，端溫(wen)差小，對(dui)水換熱可低于1℃，是其他型式換熱不能(neng)勝任的(de)。

　　板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)式換熱(re)器是由一組波紋(wen)金(jin)屬板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)組成(cheng)(cheng)，板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)上有四(si)個(ge)角孔，供傳熱(re)的(de)(de)兩種流(liu)(liu)(liu)體通(tong)過。金(jin)屬板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)片(pian)安裝(zhuang)在(zai)一個(ge)側面有固定(ding)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和活動板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)框架內，并(bing)用夾緊栓夾緊。板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)片(pian)上裝(zhuang)有密(mi)封(feng)墊片(pian)，將(jiang)流(liu)(liu)(liu)體通(tong)道(dao)密(mi)封(feng)，并(bing)且引導(dao)流(liu)(liu)(liu)體交替地流(liu)(liu)(liu)至各自的(de)(de)通(tong)道(dao)內，形(xing)(xing)成(cheng)(cheng)熱(re)交換。流(liu)(liu)(liu)體的(de)(de)流(liu)(liu)(liu)量、物理性質、壓(ya)力(li)(li)降和溫度(du)差決定(ding)了(le)(le)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)片(pian)的(de)(de)數(shu)量和尺(chi)寸。波紋(wen)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)不僅提高(gao)了(le)(le)湍流(liu)(liu)(liu)程度(du)，并(bing)且形(xing)(xing)成(cheng)(cheng)許多支撐(cheng)點(dian)，足以承受介(jie)質間(jian)的(de)(de)壓(ya)力(li)(li)差。金(jin)屬板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)和活動壓(ya)緊板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)懸(xuan)掛(gua)在(zai)上導(dao)桿，并(bing)由下導(dao)桿定(ding)位，而(er)桿端(duan)則固定(ding)在(zai)支撐(cheng)柱(zhu)上，由于具備(bei)高(gao)性能(neng)、省空間(jian)、省能(neng)源(yuan)、維護(hu)簡(jian)單等許多優點(dian)，板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)式換熱(re)器已獲(huo)得(de)各產業的(de)(de)高(gao)度(du)肯定(ding)。
