Understanding Plate Fin Heat Exchangers

A plate fin heat exchanger is a kind of heat exchanger whereby the surface area accessible for heat transfer is raised by use of plates and fins. Alternately layered corrugated fins and flat plates make up these exchangers, which produce several fluid flow channels. As the fluids pass one another through these pathways, heat is exchanged.

The Function of Fins in Plate Fin Heat Exchangers

By expanding the surface area accessible for heat transfer, fins are absolutely essential in plate fin heat exchangers. Their mechanisms are as follows:

Enhanced Surface Area: Fins give the fluids extra surface area for heat transfer between them. The heat transmission mechanism gets more effective the more surface area that is accessible.
