板(ban)(ban)(ban)式換(huan)(huan)熱(re)(re)(re)(re)(re)機(ji)組(zu)是(shi)常見(jian)的板(ban)(ban)(ban)式換(huan)(huan)熱(re)(re)(re)(re)(re)器機(ji)組(zu)型號之一，主要(yao)由不(bu)銹鋼(gang)壓(ya)制的傳熱(re)(re)(re)(re)(re)片(pian)、密封膠墊(dian)、夾緊螺栓和壓(ya)緊板(ban)(ban)(ban)整機(ji)框架等零(ling)部件(jian)(jian)組(zu)成。可(ke)(ke)(ke)(ke)耐(nai)各(ge)(ge)種腐蝕介(jie)質(zhi)。傳熱(re)(re)(re)(re)(re)效(xiao)(xiao)率高，冷熱(re)(re)(re)(re)(re)介(jie)質(zhi)通過相(xiang)鄰板(ban)(ban)(ban)片(pian)流經各(ge)(ge)自通道進行換(huan)(huan)熱(re)(re)(re)(re)(re)。由于(yu)板(ban)(ban)(ban)片(pian)上(shang)有(you)人字形波(bo)紋，介(jie)質(zhi)流動形成湍流， 因此獲得較高的換(huan)(huan)熱(re)(re)(re)(re)(re)效(xiao)(xiao)率。高效(xiao)(xiao)節能(neng)，傳熱(re)(re)(re)(re)(re)系數高。其換(huan)(huan)熱(re)(re)(re)(re)(re)系數可(ke)(ke)(ke)(ke)達3000-4500kcal/m2.゜C.h。是(shi)相(xiang)同流速下管(guan)殼式換(huan)(huan)熱(re)(re)(re)(re)(re)器的3倍以(yi)上(shang)。使用(yong)安全可(ke)(ke)(ke)(ke)靠，結構緊湊，體積小，占地少，是(shi)同等換(huan)(huan)熱(re)(re)(re)(re)(re)面積管(guan)殼式換(huan)(huan)熱(re)(re)(re)(re)(re)器的五(wu)分(fen)之一左右。組(zu)合(he)靈活，調整維修方便。松開壓(ya)緊螺母(mu)即可(ke)(ke)(ke)(ke)進行清洗(xi)維護，更換(huan)(huan)膠墊(dian)或(huo)板(ban)(ban)(ban)片(pian)。板(ban)(ban)(ban)式換(huan)(huan)熱(re)(re)(re)(re)(re)器板(ban)(ban)(ban)片(pian)均為獨(du)立元件(jian)(jian)，可(ke)(ke)(ke)(ke)按用(yong)戶要(yao)求隨(sui)意增減換(huan)(huan)熱(re)(re)(re)(re)(re)面積和流程。密封槽設置泄(xie)(xie)液(ye)液(ye)道，各(ge)(ge)種介(jie)質(zhi)不(bu)會串通，即使出現(xian)泄(xie)(xie)漏，也是(shi)向(xiang)外(wai)排出。

　　板片的定位是以五點金屬與金屬接觸而確定，上承桿的三點，可以防止板片上下移動，加上下承桿的兩點板片就不會左右移動。
　　板式換熱機組是由一組波紋金屬板組成，板上有四個角孔，供傳熱的兩種液體通過。金屬板片安裝在一個側面有固定板和活動壓緊板的框架內，并用夾緊螺栓夾緊。
　　機組(zu)板(ban)(ban)片上裝有密封(feng)墊(dian)片，將流體(ti)通道(dao)密封(feng)，并且引(yin)導流體(ti)交(jiao)替(ti)地(di)流至(zhi)各自的(de)流道(dao)內，形成熱交(jiao)換。流體(ti)的(de)流量，物(wu)理性質(zhi)，壓力降(jiang)和溫度(du)差決定(ding)了板(ban)(ban)片的(de)數(shu)量和尺寸。波紋板(ban)(ban)不(bu)僅(jin)提高(gao)了湍(tuan)流程(cheng)度(du)，并且形成許(xu)多支承點，足(zu)以承受介質(zhi)間的(de)壓力差。金屬(shu)板(ban)(ban)和活動(dong)板(ban)(ban)壓緊板(ban)(ban)懸掛(gua)在(zai)上導桿(gan)(gan)，并由下(xia)導桿(gan)(gan)定(ding)位，而桿(gan)(gan)端則固定(ding)在(zai)支撐柱(zhu)上。
