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