9.7.- 换热器

热交换器是一种在两种流体之间传递热量的机械设备。热量可以通过流体之间的接触或通过隔开它们的固体屏障来传递。它们是空调、制冷、空气调节等系统的基本元件。

直接接触式换热器是指通过两股气流的摩擦来传递热量的换热器。这种类型的换热器用于在传输过程后，流体容易分离的情况下，例如在冷却塔中。

间接接触式换热器的隔墙将两种流体隔开，热量通过对流和传导的方式传递。在间接接触式热交换器中，有两个子群。

  • 交替：流体交替地在同一空间内流动。热流体将热量传递给表面，冷流体与之接触时吸收热量。
  • 表面：热量通过固体屏障传递，将流体分开。它们在各类系统中最为广泛。根据分离面的不同，它们可以是：
  • 板式换热器：分离面为平壁。
  • 管式交换器：分离面是管壁。一个流体在管内循环，另一个管子放在外面，另一个流体通过它循环。根据电流的方向，可以是等流或逆流。

如果从它们的结构来看，我们有无数种配置的换热器，但最常见的是管壳式、同心管式和板式。

除了空调系统外，任何行业都可以看到热交换器的身影。例如海洋工业、表面处理、食品、化工和核电站。
