Fin-Shape Influencing Heat Transfer

November 03, 2021

In heat exchangers, fins or extended surfaces are usually used to improve heat transfer between the main surface and ambient fluid. Various types of folded fins, namely, offset fin/serrated fin, straight fin/plain fin, perforated fin, louvered fin, corrugated fin/wavy fin. have been used with different geometrical combinations. To fulfil heat exchanger demand, different tests have also been carried out for designing optimized fins. The optimization of fins can be performed either by enhancing heat dissipation at an exact fin weight or by diminishing the weight of the fin by precise heat dissipation. Recently a lot of work on some typical fins, like, flat top wavy fin and perforated fins, has also been carried out. Flat top fins can be closely touched with plates or tubes so that improve heat transfer rate. perforated fins are used to increase the flow of medium between channels to give off more heat.
