摘要
利用有限元CFD仿真软件对一款LED塑料包裹铝制散热套件(以下简称"塑包铝")球泡灯进行热仿真。通过对比实际测量温度及仿真温度验证所建模型及模拟步骤的正确性,并在此基础上,采用正交优化设计方法分析了塑料厚度、铝厚度等各个关键因素对散热和质量的影响,综合两者考虑得出了最佳参数组合。结果表明:通过正交试验优化后,虽然散热器质量有了一定增加,但是LED的基板温度由原来的96.05℃降为88.85℃,下降了7.2℃,散热效果得到明显改善。
In this paper,a LED plastic plated aluminum was thermal simulated by using finite element CFD. The correctness of the model and simulation steps was verified by comparing the actual measured temperature and the temperature simulation. Based on the verified model, the influence of different thickness of the plastic and aluminum and other key factors to heat dissipation and quality was analyzed by the orthogonal optimization design method. Finally,the best parameter combination was obtained through synthetically considering both. The results show that the optimized by orthogonal experiments,although radiator quality had certain increase,but the LED temperature from 96. 05 °C to 88. 85 °C,dropped by 7. 2°C,the cooling effect is greatly improved.
