Computational Study on Forced Convection Heat Transfer in Pin Fin Heat Sink (PFHS) with Inclined Wings

Abstract

Abstract Fins are used to enhance the rate of heat dissipation by increasing convection. The total amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. A pin fin heat sink is acts as a heat exchanger and transfers the heat generated by an electronic or a mechanical device to a fluid medium, where it is dissipated away from the device which helps in proper functioning of device. The present investigation deals with the CFD simulation of heat dissipation and fluid flow behavior of pin fin heat sink with straight and inclined wings. The results show that pin fin with straight wings or wings at 0 degrees dissipate more heat than pin fin with inclined wings at 15 degrees.
