固定管板式换热器

   这类的结构比较简单、紧凑、造价便宜,但管外不能机械清洗。此种换热器管束连接在管板上,管板分别焊在外壳两端,并在其上连接有顶盖,顶盖和壳体装有流体进出口接管。通常在管外装置一系列垂直于管束的挡板。同时管子和管板与外壳的连接都是刚性的,而管内管外是两种不同温度的流体。因此,当管壁与壳壁温差较大时,由于两者的热膨胀不同,产生了很大的温差应力,以至管子扭弯或使管子从管板上松脱,甚至毁坏换热器。

  ,每根管子都弯成U形,两端固定在同一块管板上,每根管子皆可自由伸缩,从而解决热补偿问题。管程至少为两程,管束可以抽出清洗,管子可以自由膨胀。其缺点是管子内壁清洗困难,管子更换困难,管板上排列的管子少。优点是结构简单,质量轻,适用于高温高压条件。
