摘要
Abstract
This work addresses the critical thermal management challenge of dramatically increasing heat flux and severe lo-calized overheating in domestically produced high-power chips within confined spaces.A macro-micro coupled cooling solu-tion based on additive manufacturing is proposed.The work employs the Gyroid configuration,a type of Triply Periodic Minimal Surface(TPMS)structure,as the core element,integrating it into the channels of traditional fins to construct a com-posite heat dissipation architecture.Through topology optimization and finite element analysis,three AlSi10Mg alloy heat sink prototypes with different structural parameters(with porosity/specific surface area of 64%/3.8,71%/3.1,and 80%/2.2,respectively)were designed and fabricated.Environmental test results demonstrate that under natural convection conditions,the optimal Gyroid structure heat sink(64%porosity,3.8 specific surface area)achieved a 16.2%reduction in maximum temperature compared to a conventional finned heat sink.Under forced convection conditions,a reduction of 9.7%was ob-served.Furthermore,this structure significantly improved temperature uniformity.This work elucidates the synergistic mechanism of key structural parameters on thermal performance,providing both theoretical and experimental foundations for the design of high-performance heat sinks for domestic chips based on additive manufacturing.关键词
