板式换热器 用板材构成传热面的间壁式换热器。这类换热器结构紧凑，单位体积的传热面积较大。主要类型有：①螺旋板式换热器由两张保持一定间距的平行金属板卷制而成（图1）,冷、热流体分别在金属板两侧的螺旋形通道内流动。这种换热器的传热系数高（约比管壳式换热器高1～4倍），平均温度差大（因冷、热流体可作完全的逆流流动），流动阻力小，不易结垢；但维修困难。使用压力不超过2MPa。②平板式换热器由一定形状的波纹薄板和密封垫片交互叠合，并用框架夹紧组装而成（图2）。冷、热流体分别在波纹板两侧的流道中流过，经板片进行换热。波纹板通常由厚度为0.5～3mm的不锈钢、铝、钛、钼等薄板冲制而成。平板式换热器的优点是传热系数高（约比管壳式换热器高2～4倍），容易拆洗，并可增减板片数以调整传热面积。操作压力通常不超过2MPa，操作温度不超过250℃。③板翅式换热器由封闭在带有冷、热流体进出口的集流箱中的换热板束构成。板束由平板和波纹翅片交互叠合,钎焊固定而成(图3)。冷、热流体流经平板两侧换热，翅片增加了传热面积，又促进了流体的湍动，并对设备有增强作用。板翅式换热器结构非常紧凑(换热面积达4400m2/m3),传热效果好，且使用压力可达15MPa。但它的制造工艺复杂，流道小,内漏不易修复，因而限用于清洁的无腐蚀性流体，如作空气分离用的换热器。
