Abstract
Heat sinks are essential components in electronic cooling systems that enhance heat dissipation to the surrounding environment. This study investigates the effect of fin material variations on heat transfer performance using Computational Fluid Dynamics (CFD). Simulations were conducted using copper, aluminum, brass, and stainless steel fins under identical geometry and operating conditions. The results show that materials with higher thermal conductivity provide better cooling performance. Copper exhibited the best thermal performance, achieving the lowest average temperature of 298.5 K and the smallest temperature difference (ΔT) of 9.0 K, followed by aluminum (302.1 K), brass (307.8 K), and stainless steel (315.4 K). The findings indicate that fin material selection significantly affects heat sink cooling effectiveness, with the thermal performance ranking of Copper > Aluminum > Brass > Stainless Steel.
Keywords: Computational Fluid Dynamics (CFD), heat sink, fin material, heat transfer, temperature distribution.
