| Summary: | 碩士 === 國立中山大學 === 機械與機電工程學系研究所 === 99 === Current high power LEDs are used popularly, energy saving can be achieved if the heat transfer performance of a high power LED is increased.
Numerical analysis is carried out herein to study the parameters effect on the cooling performance for the heat sinks of the LED projector. The parameters include fin spacing, fin depth, fin thickness, base thickness and flow speed.
The numerical results reveal that the parameters of the heat sinks significantly affects the average Nusselt Number. The results of this study can provide design references for LED projector.
