摘要
Abstract
As electronic devices become more miniaturized and multifunctional,the demand for effective heat dissipation in structures has significantly increased.Phase change materials can absorb substantial heat during phase transitions,aiding in temperature regulation.However,their low thermal conductivity limits their broader application.To address this,this paper analyzes the relationship between the equivalent properties of triple periodic minimal surface(TPMS)unit cells and the volume fraction of the metal skeleton.Building on this,a macro-micro dual-scale optimization design method is proposed.Using a density-based approach,the volume fraction distribution of the metal skeleton is optimized with the objective of minimizing thermal compliance.Numerical results demonstrate that,compared with fin structures with the same amount of metal,this method significantly reduces both the maximum and average temperatures of the chip under steady-state and transient heat transfer conditions.The findings validate the effectiveness of the proposed optimization model and offer a theoretical foundation for designing composite heat dissipation structures.关键词
