Abstract :
This paper reports a micro-tube tank device and FEM simulation using the RGB-based LED design to improve the thermal management of a high power LED arrays. An LED cooling system, using a micro-tube water-cooling device, was successfully designed and simulated. A water-cooling container in the high power LED array gave more efficient convection and the heat created by the LEDs was easily removed in the experiments. It was shown that micro-tube water-cooling systems rendered an improvement in thermal management that effectively decreases the thermal resistance and provides very good thermal dissipation. In addition, both simulation and experimental results show that the LED module with a water-cooling tube exhibits better thermal performances than the others. Accordingly, the results of experiment and simulation demonstrated that a micro-tube water-cooling system is very effective in heat dissipation in LEDs and the fabrication of practical micro-water tube cooling devices for mixing light LEDs was feasible and useful.
