针对发光二极管(LED)器件散热问题，对交错针翅式径向散热器的设计进行了优化。建立了不同针翅式阵列散热器的数值模型，并进行了实验验证。通过灵敏度分析确定了设计变量。基于热沉的热阻和质量，采用进化算法进行了多学科优化。分析结果表明，交错的针翅式径向散热器是最优结构，在保持相同质量或在给定热阻的情况下，散热器的热性能最高可提高10%或最多可减少12%。(C)2015爱思唯尔有限公司。保留所有权利。
The design of a staggered pin-fin radial heat sink was optimized for light-emitting diode (LED) device cooling. A numerical model for various pin-fin array heat sinks was developed and verified experimentally. The design variables were determined from sensitivity analysis. Multidisciplinary optimization was conducted based on the heat sink thermal resistance and mass, using an evolutionary algorithm. From the analysis results, the staggered pin-fin radial heat sink was identified as the optimal configuration, demonstrating improved thermal performance by up to 10% while maintaining the same mass or reducing the mass by up to 12% for a given thermal resistance.
