摘要
对2款外部尺寸相同、内部毛细芯结构不同的均热板进行理论分析与数值分析.结果表明,1)内部具有烧结铜粉柱体的均热板热性能更加优良,这是由于烧结铜粉柱体缩短了工质的回流通路与时间;2)数值分析对均热板结构优化与热性能的提高具有指导意义.
In this paper we show the results of numerical simulation and theoretical analysis for two vapor chambers having the same external structure but different internal wick structures. The results show that the vapor chamber with wick bracing pillar has a better thermal performance because wick bracing pillar accelerates fluid circulation and that the numerical simulation can be used for structural optimization and has the guiding significance for improvements in thermal performance of vapor chambers.
