Abstract:
This study performed a steady-state numerical analysis to understand the temperature in different heat
sink configurations for LED applications. Seven heat sink configurations named R, H-6, H-8, H-10, C, C3, and C3E3
were considered. Parameters like input power, number of fins, heat sink configuration were varied, and their
influence on LED temperature distribution, heat sink thermal resistance and thermal interface material
temperature were studied. The results showed that the temperature distribution of the H-6 heat sink decreased by
46.30% compared with the Cheat sink for an input power of 16 W. The result of the H-6 heat sink shows that the heat
sink thermal resistance was decreased by 73.91% compared with the Cheat sink at 16 W. The lowest interface
material temperature of 54.11 °C was achieved by the H-6 heat sink when the input power was used 16 W. The H-6
heat sink exhibited better performance due to more surface area with several fins than other heat sinks.
