Extended surface heat exchangers

 Extended surface heat exchangers


In some applications, a much higher exchanger efficiency (up to about 98%) is essential, and the volume and mass of the box are limited so that a much more compact surface is mandatory. plate and Tubular exchangers are all main surface heat exchangers, except for a shell and tube exchanger with low finned tubing

In addition, in a heat exchanger with gases or some liquids, the heat transfer coefficient is quite low on one or both sides of the fluid. This results in a great need for the heat transfer surface area.

One of the most common methods for increasing the exchanger's surface area and compaction is to add the extended surface (fins) and use fins with the density of the fins (frequency of the fins, fins / m or fins / in.) As high as possible in one or both sides of the fluid, depending on the project requirements.

The addition of fins can increase the area of surface by 6 to 15 times the primary surface area in general, depending on the design of the object.


The flow area is increased by the use of thin gauge material and the proper sizing of the core.

The heat transfer coefficient on extended surfaces can be higher or lower than on uncoated surfaces.
