      是(shi)由(you)一系(xi)列具有(you)一定(ding)波紋形(xing)狀的(de)(de)(de)金屬片(pian)疊裝而成(cheng)的(de)(de)(de)一種新式(shi)高效(xiao)換(huan)(huan)熱(re)(re)(re)器(qi)各(ge)種板(ban)(ban)(ban)片(pian)之間形(xing)成(cheng)薄長方形(xing)通道,經由(you)過程半(ban)片(pian)進行(xing)熱(re)(re)(re)能(neng)互(hu)換(huan)(huan)它與通例的(de)(de)(de)管(guan)(guan)殼式(shi)換(huan)(huan)熱(re)(re)(re)器(qi)相比,在相同的(de)(de)(de)流動阻力(li)和(he)泵功率消耗情況下,其傳熱(re)(re)(re)系(xi)數要(yao)(yao)高出很多,在適用(yong)的(de)(de)(de)規模內有(you)代替管(guan)(guan)殼式(shi)換(huan)(huan)熱(re)(re)(re)器(qi)的(de)(de)(de)趨(qu)勢。鈦(tai)板(ban)(ban)(ban)式(shi)換(huan)(huan)熱(re)(re)(re)器(qi)、熱(re)(re)(re)互(hu)換(huan)(huan)器(qi)行(xing)業板(ban)(ban)(ban)片(pian)常用(yong)的(de)(de)(de)材料(liao)主要(yao)(yao)有(you)奧氏體不(bu)銹鋼、鈦(tai)及鈦(tai)合金、鎳及鎳合金等(deng)冷軋薄板(ban)(ban)(ban)工(gong)業純(chun)鈦(tai)127用(yong)于板(ban)(ban)(ban)式(shi)換(huan)(huan)熱(re)(re)(re)器(qi),工(gong)業純(chun)鈦(tai)276和(he)Ti-0.3Mo-0.8Ni345用(yong)于管(guan)(guan)式(shi)換(huan)(huan)熱(re)(re)(re)器(qi)用(yong)TA1鈦(tai)板(ban)(ban)(ban)打(da)造的(de)(de)(de)板(ban)(ban)(ban)式(shi)換(huan)(huan)熱(re)(re)(re)器(qi),相比列管(guan)(guan)式(shi)換(huan)(huan)熱(re)(re)(re)器(qi)有(you)很多長處,在市場上(shang)有(you)很強的(de)(de)(de)競爭力(li),主要(yao)(yao)用(yong)于化工(gong)、石(shi)油、艦船、海(hai)水淡化等(deng)熱(re)(re)(re)互(hu)換(huan)(huan)系(xi)統。

  板(ban)式(shi)換熱器(qi)在(zai)設計(ji)上主要(yao)有以下獨(du)特之處:

  (1)高效節能:其換熱(re)系數(shu)在3000~4500 kcal/m2?℃?h,比管殼式換熱(re)器的(de)熱(re)效率高3~5倍。

  (2)緊湊密切:板(ban)(ban)式換熱(re)器(qi)(qi)板(ban)(ban)片精密排列,與其它(ta)換熱(re)器(qi)(qi)類型相比(bi),板(ban)(ban)式純鈦鏡架(jia)有什么(me)特點換熱(re)器(qi)(qi)的(de)占地面積和占用空間較(jiao)少,相同換熱(re)能(neng)的(de)板(ban)(ban)式換熱(re)器(qi)(qi)的(de)面積僅為管殼式換熱(re)器(qi)(qi)的(de)1/5。

  (3)容(rong)易(yi)清(qing)洗(xi)(xi)拆(chai)裝利便:板(ban)式(shi)換熱(re)器靠夾緊螺栓(shuan)將夾固板(ban)板(ban)片夾緊,因此拆(chai)裝利便,任何(he)時間(jian)可(ke)以(yi)打開清(qing)洗(xi)(xi),同時因為板(ban)面光潔,湍流深(shen)重,不易(yi)結(jie)水(shui)垢。

  (4)不串(chuan)液,板式換熱器密封槽設置(zhi)泄(xie)液道,各(ge)種(zhong)介(jie)質不會(hui)串(chuan)通,即使(shi)浮現泄(xie)露(lu),介(jie)質總(zong)是向外排出。

  (5)施用壽命長:板(ban)(ban)式換熱器采用不(bu)銹鋼或(huo)鈦合金板(ban)(ban)片(pian)壓制,可耐(nai)各(ge)種腐化介質(zhi),膠墊可隨心(xin)改換,并(bing)可利便拆裝(zhuang)檢(jian)修。

  (6)適(shi)應性強:板(ban)式換熱器板(ban)片(pian)為自力元(yuan)件,可按要求(qiu)隨心增(zeng)減(jian)流程,情勢多樣;可適(shi)用于各種(zhong)差別工藝(yi)的要求(qiu)。

  鈦(tai)(tai)板(ban)(ban)式(shi)換熱(re)器(qi)(qi)的(de)基本構造:鈦(tai)(tai)板(ban)(ban)式(shi)換熱(re)器(qi)(qi)主(zhu)要由(you)框架(jia)和(he)鈦(tai)(tai)板(ban)(ban)片2大多構成(cheng)板(ban)(ban)片是把由(you)各種(zhong)材料制成(cheng)的(de)薄板(ban)(ban)用各種(zhong)差(cha)別情勢的(de)生(sheng)產模(mo)型壓(ya)成(cheng)形(xing)狀各別的(de)波紋(wen),并在(zai)板(ban)(ban)片4個角(jiao)(jiao)上開(kai)有角(jiao)(jiao)孔,用于介(jie)質的(de)流道(dao)板(ban)(ban)片的(de)周邊及(ji)角(jiao)(jiao)孔處用橡膠(15260, -775.00, -4.83%)墊(dian)片加(jia)以(yi)密封(feng)框架(jia)由(you)固定(ding)壓(ya)緊(jin)(jin)板(ban)(ban)、勾當壓(ya)緊(jin)(jin)板(ban)(ban)、上下導桿(gan)和(he)夾(jia)緊(jin)(jin)螺栓(shuan)等構成(cheng)板(ban)(ban)式(shi)換熱(re)器(qi)(qi)是將(jiang)板(ban)(ban)片以(yi)疊加(jia)的(de)情勢裝在(zai)固定(ding)壓(ya)緊(jin)(jin)板(ban)(ban)、勾當壓(ya)緊(jin)(jin)板(ban)(ban)中間(jian),然后用夾(jia)緊(jin)(jin)螺栓(shuan)夾(jia)緊(jin)(jin)而成(cheng)。
