INVESTATION OF THERMAL PERFORMANCE OF ALUMINIUM CASTED V-SHAPED FIN ARRAYS WITH DIFFERENT NOTCH CONFIGURATION, INCLINATION AND VARIABLE POWER SUPPLY

Abstract

Heat generation is a common issue in industrial devices, and thus efficient thermal management solutions are sought to improve performance and reduce overheating. Heat sinks that use fins are widely used in applications as heat exchangers, engines, electric motors and electronic devices, the fins being used to promote heat dissipation by naturalor forced convection.Researchershave worked over the years to optimize and understand how fin material, geometry, dimensions, and inclination affect heat transfer. Although the augmentation of natural convection heat transfer in V shaped fins, with varied notch sizes and surface angles is relatively underexplored, however. The effect of geometric parameters such as notch size and surface angle on the natural convection performance of V-shaped fins is analyzed in this experimental investigation. It is found that the heat transfer coefficient and Nusselt number are maximized at 60° surface inclination, and 20 mm notch size, which offers the potential for sustained improved heat dissipation through optimized fin configurations.
