Advantage of Fin Tube Heat Exchanger

鳍管交换机的使用特别适合空气热交换器。鳍管为管子外的流体增加了很多传热表面积，该液通常是空气或鳍管交换机的其他气体。

介绍

对于液态液热交换器，通常不需要使用鳍管，因为传热表面两侧的传热系数相对较高。必威体育哪个是真的然而，对于空气热交换器，其中一种流体是空气或其他气体，空气侧传热系数将要低得多，因此，额外的传热表面积（如鳍管口气中）非常有帮助。必威体育哪个是真的鳍管交换器的总流量通常是交叉流，但也可以是逆流或平行流。

鳍管交换机的一般配置

A finned tube heat exchanger will typically have tubes with fins attached to the outside of them. There will usually be a liquid flowing through the inside of the tubes and air or some other gas flowing outside of the tubes, where the additional heat transfer surface area due to the finned tube, increases the heat transfer rate. For a crossflow fin tube exchanger, the fins will typically be radial fins either circular or square, as shown in the pictures in this section.

大多数鳍管热交换器都是交叉流，使用鳍的管有点像上图。对于逆流或平行流鳍管交换器，鳍应为纵向而不是径向，如左下图所示。鳍管可以用作封闭的热交换器中的内部管，但是在许多情况下，带有空气热交换器，空气通过开放的热交换器流动，如下一部分所示，在其中显示了一些典型的鳍管热交换器应用并讨论。

鳍管热交换器的示例

翅片管换热器是用于各种不同of household applications and as industrial heat exchangers. An air heat exchanger like the evaporator coil for an air conditioning unit is typically a fin tube heat exchanger. Another common fin tube air heat exchanger is the car radiator. The purpose of the car radiator is to cool the hot water in the tubes with the air passing through in crossflow. The air conditioner evaporator coil has the purpose of cooling the air passing through it.

鳍管热交换器也可以用作工业热交换器。最近看到广泛扩展的应用程序是蒸汽发电厂的“干冷却”。这包括使用空气冷却冷凝器而不是水冷却冷凝器。由于担心传统冷却系统对水体的量以及“一旦通过冷却”和“封闭系统 - 冷却塔冷却，对蒸汽发电厂的干冷却感兴趣的兴趣增加了。
