板式換熱器

1.jpg  2.jpg 



  板式換熱器廣泛應用于供熱取暖、熱水洗浴、空調、液壓油冷卻、石油化工、制藥、食品加工等領域。

  板式換熱器是目前各類換熱器中換熱效率最高的一種換熱器,它占用空間小,安裝拆卸方便。

  板式換熱器主要部件是由換熱板片、密封膠墊、夾緊板、導桿、夾緊螺栓組成。換熱板片是由不銹鋼板壓制成型,它上面開有4個流道孔,中部壓成人字形波紋,四周壓有密封槽。密封槽內粘有密封膠墊。換熱板片通過兩導桿定位對齊,兩夾緊板通過夾緊螺栓將各板片壓緊,從而形成換熱器內腔換熱流道。相鄰換熱板片的人字形波紋方向安裝時相反,接觸點彼此相互支撐。人字形波紋和這些支撐點使流體介質在其內部流動時充分形成湍流,這是板式換熱器具有很高換熱效率的主要原因。另外換熱板片厚度較薄,導熱熱阻較小,板片兩側的流體介質流動分布較為均衡,也使得傳熱較為充分。
