摘　　要：将阳极保护管壳式浓酸冷却器的壳程挡板设计成带旁流孔的碟形挡板和环形挡板后 ,流体速度场与保护电流强度场相一致 ,克服了阴极套管对换热器换热效果的影响 ,且具有传热系数高、布管半径小、设备重量轻、自清洗能力好、使用寿命长等优点。与圆缺折流挡板相比较 ,可使壳程给热系数提高 40 %以上。Fluid velocity field accordant with protecting electric field eliminates adverse effect of cathod tube on heat transfer due to disc and doughnut baffles with by pass holes designed in anodically protected shell and tube acid cooler The cooler is characteristic of high transfer cofficient,small radius of tube laying,less weight,good capacity of self cleaning and long service life The heat transfer cofficient on the shell side will be increased by 40% against with segmental baffles 〔
