What is fin pitch in heat exchanger?
Fin pitch refers to the spacing between the fins of a finned heat exchanger. It is often confused as a measure of the fin density which is expressed in terms of fins per inch (FPI). Fin pitch is measured from the centerline of one fin to another and can be determined from summing the fin spacing (distance between fins) and the fin thickness. Generally speaking, smaller fin pitches result in more dense fin arrays which can remove more heat. A point of diminishing returns exists in which the heat exchanger is too dense resulting in insufficient flow of the cooling fluid between fins.
