可(ke)拆卸(xie)板(ban)式換熱器是由許多沖壓有波紋薄板(ban)按一定間隔，四(si)周通過(guo)墊(dian)片密(mi)封，并(bing)用(yong)框架和壓緊螺(luo)旋重(zhong)疊壓緊而成(cheng)，板(ban)片和墊(dian)片的(de)四(si)個角孔形成(cheng)了流體(ti)的(de)分配管和匯(hui)集管，同時又合理地將冷熱流體(ti)分開，使其分別在每塊板(ban)片兩側的(de)流道中流動，通過(guo)板(ban)片進行(xing)熱交換。

板式(shi)換熱器(qi)的工作原理

板(ban)(ban)式換(huan)熱器(qi)是用(yong)(yong)薄金(jin)屬板(ban)(ban)壓制成(cheng)(cheng)具有(you)一定波紋形狀的(de)換(huan)熱板(ban)(ban)片(pian)(pian)，然后(hou)疊裝(zhuang)，用(yong)(yong)夾板(ban)(ban)、螺栓緊固而成(cheng)(cheng)的(de)一種換(huan)熱器(qi)。各(ge)種板(ban)(ban)片(pian)(pian)之間形成(cheng)(cheng)薄矩形通(tong)道(dao)(dao)，通(tong)過半片(pian)(pian)進行(xing)熱量交換(huan)。工作流體在兩塊板(ban)(ban)片(pian)(pian)間形成(cheng)(cheng)的(de)窄(zhai)小(xiao)(xiao)而曲折的(de)通(tong)道(dao)(dao)中流過。冷熱流體依次(ci)通(tong)過流道(dao)(dao)，中間有(you)一隔層板(ban)(ban)片(pian)(pian)將(jiang)流體分(fen)開，并通(tong)過此(ci)板(ban)(ban)片(pian)(pian)進行(xing)換(huan)熱。板(ban)(ban)式換(huan)熱器(qi)的(de)結(jie)構(gou)及換(huan)熱原(yuan)理決定了其具有(you)結(jie)構(gou)緊湊(cou)、占地面積小(xiao)(xiao)、傳熱效率高、操作靈活(huo)性(xing)大、應用(yong)(yong)范圍廣(guang)、熱損失小(xiao)(xiao)、安裝(zhuang)和清洗方便等特點。
