Research Progress on Aluminum Alloy with High Thermal Conductivity
Aluminum alloys are widely used in the field of electronic communications due to the lightweight,low cost,and desirable thermal conductivity.Electronic products and communication devices are becoming more lightweight and integrated,leading to an increasing heat dissipation per unit volume,and conventional thermal conductive aluminum alloys cann't meet the requirements.The domestic and overseas research progress in aluminum alloys with high thermal conductivity were summarized.The thermal conduction mechanism of aluminum alloys was briefly described,and effects of elements,casting methods,and heat treatment on the thermal conductivity of alloys were expounded in detail.In addition,the research status of quantitative models for thermal conductivity of aluminum alloys were reviewed,including Wiedemann-Franz Law,series-parallel model,Maxwell model,and Hashin-Shtrikman model.Finally,the future development of high thermal conductivity aluminum alloys was prospected.
