摘要：
The objective of this paper is to design and fabricate an integrated radial heat sink with thermosyphon for high-power LEDs applications. Effects of different structural parameters on the thermal resistance of the radial heat sink were firstly analyzed in terms of the theory of thermal resistance network. Subsequently, numerical simulation was applied to analyze thermal properties of the fin upon which the optimized structural parameters were obtained with the assistance of orthogonal test. Finally, the integrated radial heat sink with the optimized structural parameters was fabricated and then tested. Numerical and experimental results agree with each other showing that the maximum temperature, temperature uniformity and the thermal resistance of the heat sink are satisfied for high-power LEDs applications.
