PHE可拆板(ban)式(shi)換(huan)熱器流程演(yan)示圖：

　　● 高(gao)效節能：其換熱系數(shu)在3000～4500kcal/ m2.℃·h，比(bi)管殼式換熱器的熱效率高(gao)3~5倍。

　　●   結(jie)構緊湊：板式(shi)(shi)換(huan)熱(re)(re)(re)器(qi)板片緊密排列，與(yu)其他(ta)換(huan)熱(re)(re)(re)器(qi)類型相比，板式(shi)(shi)換(huan)熱(re)(re)(re)器(qi)的占地面(mian)積(ji)和占用空間較少，面(mian)積(ji)相同換(huan)熱(re)(re)(re)量的板式(shi)(shi)換(huan)熱(re)(re)(re)器(qi)僅為管殼式(shi)(shi)換(huan)熱(re)(re)(re)器(qi)的1/5。

　　● 容易清洗(xi)拆裝方便：板式換熱器靠(kao)夾緊螺栓將夾固(gu)板板片夾緊，因(yin)此拆裝方便，隨(sui)時(shi)(shi)可以打開清洗(xi)，同時(shi)(shi)由于板面光(guang)潔，湍(tuan)流程度高，不(bu)易結垢。

　　● 使用壽命(ming)長(chang)：板式換熱器采用不(bu)銹(xiu)鋼板片壓制，可耐各種(zhong)腐蝕介(jie)質，膠墊可隨意更換，并可方便在(zai)、拆裝檢修。

　　● 適(shi)應性強：板(ban)(ban)式換熱器板(ban)(ban)片為獨(du)立元件，可(ke)按要求隨意增減流程(cheng)，形式多樣;幾乎適(shi)用于所(suo)有領域的(de)加熱、冷卻、蒸發、冷凝(ning)、保溫、殺菌(jun)過程(cheng)。

　　● 不串(chuan)液(ye)(ye)：板式換熱器(qi)密封槽設置泄液(ye)(ye)液(ye)(ye)道，各(ge)種介(jie)質不會串(chuan)通，即使(shi)出現泄露，介(jie)質總是向外(wai)排出。

　　●   能(neng)實現(xian)純逆流換熱(re)(re)(re)：充(chong)分(fen)利用(yong)兩種(zhong)流體的溫(wen)差，熱(re)(re)(re)回收率高達95%以上，處理微小溫(wen)差的能(neng)力最強，端溫(wen)差小，對水換熱(re)(re)(re)可(ke)低于1℃，是其他(ta)型式換熱(re)(re)(re)不(bu)能(neng)勝(sheng)任(ren)的。

　　板(ban)(ban)(ban)(ban)(ban)(ban)式換熱器(qi)是由一組波紋金(jin)屬(shu)板(ban)(ban)(ban)(ban)(ban)(ban)組成，板(ban)(ban)(ban)(ban)(ban)(ban)上(shang)有四個角孔，供傳熱的(de)(de)兩種流(liu)體(ti)通過。金(jin)屬(shu)板(ban)(ban)(ban)(ban)(ban)(ban)片(pian)安裝(zhuang)在(zai)一個側(ce)面有固(gu)定(ding)板(ban)(ban)(ban)(ban)(ban)(ban)和活(huo)動(dong)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)框(kuang)架內(nei)，并(bing)(bing)(bing)用夾(jia)緊栓夾(jia)緊。板(ban)(ban)(ban)(ban)(ban)(ban)片(pian)上(shang)裝(zhuang)有密封(feng)墊(dian)片(pian)，將流(liu)體(ti)通道密封(feng)，并(bing)(bing)(bing)且引導流(liu)體(ti)交(jiao)替地流(liu)至各自的(de)(de)通道內(nei)，形(xing)成熱交(jiao)換。流(liu)體(ti)的(de)(de)流(liu)量(liang)、物理(li)性(xing)(xing)質(zhi)、壓(ya)(ya)(ya)力降和溫(wen)度差(cha)決定(ding)了板(ban)(ban)(ban)(ban)(ban)(ban)片(pian)的(de)(de)數(shu)量(liang)和尺寸。波紋板(ban)(ban)(ban)(ban)(ban)(ban)不僅(jin)提高了湍(tuan)流(liu)程度，并(bing)(bing)(bing)且形(xing)成許多(duo)支撐點，足以承受(shou)介質(zhi)間(jian)的(de)(de)壓(ya)(ya)(ya)力差(cha)。金(jin)屬(shu)板(ban)(ban)(ban)(ban)(ban)(ban)和活(huo)動(dong)壓(ya)(ya)(ya)緊板(ban)(ban)(ban)(ban)(ban)(ban)懸掛在(zai)上(shang)導桿(gan)，并(bing)(bing)(bing)由下(xia)導桿(gan)定(ding)位，而桿(gan)端則固(gu)定(ding)在(zai)支撐柱上(shang)，由于具備高性(xing)(xing)能、省(sheng)空(kong)間(jian)、省(sheng)能源、維護簡單等(deng)許多(duo)優點，板(ban)(ban)(ban)(ban)(ban)(ban)式換熱器(qi)已獲得各產業的(de)(de)高度肯定(ding)。
