Abstract:

为满足大功率LED散热器急需增强散热性能且减轻重量的设计要求,采用正交试验设计法和遗传算法两种优化方法,对芯片结温和肋片重量实施了双目标优化。在确定优化变量时,借鉴了前期的研究结果,选择肋片的间距、高度和厚度为待优化的结构变量,并依据建议结构设置了各变量的约束范围,进而采用等效热路法和肋片重量表达式分别计算出不同变量组合情况下的芯片结温和肋片重量。在实施散热器结构优化的过程中,介绍了两种优化方法的具体执行方案,二者均需要采用权重加合法来构建双目标优化的评价函数。从双目标优化前后的效果对比可以看出,两种方法均能提供合理的Pareto最优解,优化效果明显,且遗传算法能提供更加多样的优化结构。
