Fin fan heat exchanger calculations.
Fin efficiency and fin resistance the general concept of fin efficiency and fin resistance was developed in chapter 1.
It is also referred to as an air cooled heat exchanger.

Fins are used to increase heat transfer area and provide a cooling effect.
A fin fan is a type of heat exchanger that forces air over a set of coils to cool the process.
