Heat Transfer Enhancement in Heat Exchanger using Double Sinusoidal Shape Fins

Abstract

The improvement of heat transmission in compact heat exchangers is a challenging and continuous area of study for heat exchanger applications. Without expanding the heat exchanger's overall volume, the current study takes into consideration a small heat exchanger that is used in the cooler device for the enhancement study. To calculate the potential using CFD, enhancements to the current flat-finned heat exchanger are simulated for pressure loss and fan discharge modeling. The current study's primary goal is to alter the fin profile to enhance heat transmission without increasing a significant pressure drop, which is accomplished via a perforated, wavy fin. Variations in the perforation's pitch and diameter are taken into account during simulation, and the resulting pitch and perforated profile are then experimentally assessed to determine whether the cooling effects improve. By using simulation, it is discovered that the cooling effect is improved by 28% and that the pressure drop caused by the fin's perforation is reduced by 4.5% when compared to the current design.
