title = "A CFD analysis and optimization of a cooling solution for LED in micro projector",
abstract = "In this paper, Computational fluid dynamics (CFD) analysis and design of experiment (DOE) are employed to optimize the thermal performance of LED in micro projector. First, an original micro-projector is simulated using Flotherm which shows that the junction temperature of LED exceeds the temperature limit. Secondly, a solution redesigning the air duct and reducing the effect of flow bypass and fan hub on the performance of heat sink lowers the junction temperature by 8 °C. At last, DOE is applied to find the optimal setting of the design parameters for the heat sink, which reduced the LED junction temperature by 13°C. In addition, a test has been presented and the result demonstrates that the error is less than 10\%.",
