This research is to investigate the cooling performance analysis of the heat sinks for LED lightwith four different fin types and two different fin numbers (16EA and 64EA) of heat sinks. Temperaturedistributions of fins over the flow domain are numerically calculated for the optimum design of heatsink fin types with uniform initial temperature of the bottom of the fins. According to the calculationsof convective heat transfer coefficient between fin and atmosphere in the flow domain, S-curve fin typeof heat sinks with 64EA of fins reveals the highest cooling performance of the heat sink fin types inthe present cooling heat sink model.
