Fin Fan Heat Exchanger Design

The serrations improve the heat transfer rate and allow for smaller footprint designs.

Fin fan heat exchanger design.

A fin fan is a type of heat exchanger that forces air over a set of coils to cool the process. It is also referred to as an air cooled heat exchanger. Embedded fins are applied by first plowing or rolling a continuous spiraling groove into the outer surface of the tube. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to volume ratio.

Since fins are used in the cooler it is called as fin fan cooler. Air cooled heat exchangers also known as fin fan heat exchangers are typically used in applications where water is not available or the desired process outlet temperature can be achieved given the maximum ambient temperatures. A plate fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. Finned tube exchangers are known for maximizing heat transfer surface area by design.

In the fin fan coolers the ambient air used as the cooling media to cool. Fin fan cooler is nothing but traditional name of air cooled heat exchanger. Please refer air cooled heat exchanger for all the details. A strip of fin material is then wound on edge into this groove followed by a mechanical process that either peens or rolls the tube material against the inserted fin.

Fin fan heat exchangers are generally used where a process system generates heat which must be removed but for which there is no local use. Air cooled heat exchangers or air fin fan coolers or air fin coolers or air coolers are one of the heat exchanger types frequently used in process power and steel industries where a process system generates heat which must be removed for which there is no local use. Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins.
