[Closed] Plate Fin Heat Exchangers

In this design, heat is moved between fluids through finned chambers and plates. It’s composed of a number of corrugated sheets, each of which is separated by smooth, metal plates. This results in finned chambers. Both hot and cold fluids flow through different layers. The heat transfer occurs through the fins, which also strengthen the structure of these heat exchangers. The fins can come in a number of types: plain, perforated, serrated, and herringbone. Basically, heat moves via a fin to a plate through to the next fin and then onto the subsequent flowing fluid. A main drawback in this design is that it’s hard to clean.
