综述了相变材料（PCM）通过金属（铜、镍、铝）、碳基（碳、石墨和膨胀石墨）及纳米颗粒多孔材料/泡沫来增强传热性能的研究概况。总结了孔隙度和孔隙密度对传热、导热系数、比热、潜热和充放电时间的影响。通过多孔材料/泡沫材料改性PCM可以有效地使传热/导热系数提高3~500倍。最后，对相变材料传热技术的发展做出展望。

This review summarizes the research situation on enhancing the heat transfer performance of phase change materials (PCM) through adding metals (copper,nickel and aluminum),carbon-based materials (carbon,graphite,and expanded graphite) and nanoparticle porous materials/foam.The effects of porosity and pore density on heat transfer,thermal conductivity,specific heat,latent heat and charge/discharge time are analyzed.Modification of PCM by porous material/foam can effectively increase the heat transfer/thermal conductivity by 3 to 500 times.Finally,the future development of phase change material heat transfer technology is expected.
