摘要

A novel cooling system based U-shaped heat pipe with fan is proposed firstly to solve thermal management of high-power LEDs, and the thermal performance of the proposed cooled device is investigated based on the experiment combined with the finite element analysis (FEA). The experimental results show that the substrate temperature is only 25 °C when cooling by the combination of the heat pipe and fan. FEA model of the cooling system is established, and its effectiveness is validated with the experimental ones. FEA simulation results indicate that the LEDs junction temperature can get very good control as long as appropriate ambient temperature and volume flow rate, and the LED power cooled by the system can reach to 120 W while the total power consumption of cooling system is only 1.58 W. The investigation demonstrates that the U-shaped heat pipe cooling device has excellent cooling capacity.
