7、程设计1前言换热器（英语翻译：heatexchanger），是将热流体的部分热量传递给冷流体的设备，又称热交换器。换热器是化工、石油、动力、食品及其它许多工业部门的通用设备，在生产中占有重要地位。在化工生产中换热器可作为加热器、冷却器、冷凝器、蒸发器和再沸器等，应用更加广泛。换热器种类很多，但根据冷、热流体热量交换的原理和方式基本上可分三大类即：间壁式、混合式和蓄热式。列管式换热器工业上使用最广泛的一种换热设备。其优点是单位体积的传热面积、处理能力和操作弹性大，适应能力强，尤其在高温、高压和大型装置中采用更为普遍。列管式换热器主要有

8、以下几个类型：固定管板式换热器、浮头式换热器、U形管式换热器等。设计一个比较完善的列管式换热器，除了能满足传热方面的要求外，还应该满足传热效率高、体积小、重量轻、消耗材料少、制造成本低、清洗维护方便和操作安全等要求。列管式换热器的设计
