摘　　要：铝合金具有密度小、强度高、导电导热性能好的优点,因此被广泛应用于电子及通讯行业。但是随着系统及设备都趋向于小型化、轻量化,并且功率密度的增加,对散热要求越来越高,常规铝合金已不能满足要求。文中重点阐述了高导热铝合金的分类、导热机理、影响导热性能的因素,并对目前国内外的研究进展情况进行了初步梳理和总结,对提高铝合金导热性能的研究方向给出了一些建议。Aluminum alloys have been used widely in electronics and communications industries because of their low density, high strength, good electric and thermal conductivity. However, since some systems and equipment tend to be miniaturized, lightweight, and with the increase of power density, the requirement for heat dissipation is getting higher and higher. Therefore, the conventional aluminum alloys have not met the requirements of design and application. This paper expounds the high thermal conductivity aluminum alloys’ classification, the mechanism of thermal conductivity and the factors affecting the thermal conductivity. The research progress at home and abroad is summarized, and the research direction of improving the thermal conductivity of aluminum alloys is advised.
