基于平板热管的大功率LED散热系统模拟及优化
Simulation and optimization of high-power LED with flat heat pipe heat spreader
摘要
Abstract
Flat heat pipe heat spreader was designed for the heat dissipation of high-power LED. The thermal performance of high-power LED in natural convection conditions was simulated by the Flotherm simulation software. It is found that the flat heat pipe reduces the junction temperature and thermal resistance compared to the conventional copper and alumina heat spreader. The thermal performance of LED with flat heat pipe heat spreader under different heat power conditions was also explored. Furthermore, four types of arrangement of the LED chips were also designed and compared for the optimization. The results indicate that the uniform array configuration induces the best uniform temperature distribution and the lowest junction temperature, and seems to be the optimum choice for high-power LED.关键词
