The inlet baffle spacing is less than the recommended minimum spacing. Check the design. This condition may lead to problems when the exchanger is built. The outlet baffle spacing is less than the recommended minimum spacing. Check the design. This condition may lead to problems when the exchanger is built. Setting plan error: Axial nozzle location is not supported by setting plan calculation code.

HTRI Exchanger 使用手册一、换热器的基础设计知识1。

1 换热器的分类1．按作用原理和实现传热的方式分类(1）混合式换热器;(2)蓄热式换热器；（3）间壁式换热器其中间壁式换热器按传热面的形状和结构分类:(1)管壳式:固定管板式、浮头式、填料函式、U型管式(2）板式:板翅式、平板式、螺旋板式(3)管式：空冷器、套管式、喷淋管式、箱管式（4）液膜式：升降膜式、括板薄膜式、离心薄膜式（5）其他型式：板壳式、热管2．按换热器服务类型分类：(1）交换器(Exchanger): 在两侧流体间传递热量。

(2）冷却器（Chiller）:用制冷剂冷却流体.制冷剂有氨（Ammonia)、乙烯、丙烯、冷却水(Chilled water)或盐水(brine). （3）冷凝器（Condenser）：在此单元中,制程蒸汽被全部或部分的转化成液体。

（4)冷却器（Cooler)：用水或空气冷却，不发生相变化及热的再利用。

(5)加热器（Heater）：增加热函,通常没有相变化，用如Dowtherm或热油作为热媒加热流体。

（6)过热器（Superheater):高于蒸汽的饱和蒸汽压进行加热.（7）再沸器（Reboiler）：提供蒸馏潜热至分流塔的底部。

(8）蒸汽发生器（Steam generator）(废热锅炉(waste heat boiler））：用产生的蒸汽带走热流体中的热量。

通常为满足制程需要后多余的热量。

（9）蒸馏器(Vaporizer)：是一种将液体转化为蒸汽的交换器，通常限于除水以外的液体。

(10)脱水器(Evaporator）：将水蒸气浓缩为水溶液通过蒸发部分水分以浓缩水溶液.1.2换热器类型管壳式换热器(Shell and Tube Exchanger):主要应用的有浮头式和固定管板式两种。

－应用：工艺条件允许时,优先选用固定管板式，但下述两种情况使用浮头式：a)壳体和管子的温度差超过30度，或者冷流体进口和热流体进口温度差超过110度;b)容易使管子腐蚀或者在壳程中容易结垢的介质。
