Thermal performance of an impinging cooling module for 150 W class high power LEDs have been investigated numerically and experimentally. Parametric studies were performed to compare the effect of several design parameters such as nozzle number, nozzle spacing, coolant flow rate, and impinging distance. The experiments were also carried out in order to validate the numerical results and the comparison between the experimental and numerical results showed good agreement. It is found that the overall thermal resistance of impinging cooling module strongly depends on the nozzle number, nozzle spacing, flow rate, and impinging distance. This results showed the optimized operating condition when number of nozzles is 25, nozzles spacing is 4mm, flow rate is 2.70 lpm, distance between nozzles and impinging surface is 2 mm.
