板式換熱器 BR0.85-80 BR0.85-85 無錫溫納

板式換熱器是由一系列具有一定波紋形狀的金屬片疊裝而成的一種高效換熱器。各種板片之間形成薄矩形通道，通過板片進(jìn)行熱量交換。板式換熱器是液—液、液—汽進(jìn)行熱交換的理想設(shè)備。它具有換熱效率高、熱損失小、結(jié)構(gòu)緊湊輕巧、占地面積小、應(yīng)用廣泛、使用壽命長(zhǎng)等特點(diǎn)。在相同壓力損失情況下，其傳熱系數(shù)比管式換熱器高3-5倍，占地面積為管式換熱器的三分之一，熱回收率可高達(dá)90%以上。

板式換熱器的型式主要有框架式（可拆卸式）和釬焊式兩大類，板片形式主要有人字形波紋板、水平平直波紋板和瘤形板片三種。

結(jié)構(gòu)原理可拆卸板式換熱器是由許多沖壓有波紋薄板按一定間隔，四周通過墊片密封，并用框架和壓緊螺旋重疊壓緊而成，板片和墊片的四個(gè)角孔形成了流體的分配管和匯集管，同時(shí)又合理地將冷熱流體分開，使其分別在每塊板片兩側(cè)的流道中流動(dòng)，通過板片進(jìn)行熱交換。BR0.05-0.5,BR0.05-0.75,BR0.05-1.0,板式換熱器,BR系列板式換熱器,不銹鋼換熱器無錫溫納廠家
