石蜡/碳基复合相变材料热性能研究进展

Research progress on thermal property of paraffin/carbon-based composite phase change material

在有机相变材料中,石蜡由于优越的性能得到了学者们的广泛关注。然而,较低的热导率和较差的蓄/释热特性,也是制约其发展和应用的巨大瓶颈。碳基材料因具有较高的热导率,常被用作导热添加剂来提高相变材料的热性能。综述了不同维度碳基材料对石蜡/碳基复合相变材料传热性能和储热性能的影响,总结了其热性能研究进展中的不足之处,并指出了石蜡/碳基复合相变材料热性能研究的未来发展方向。

Among all of organic phase change materials(PCM),paraffin has been widely concerned due to its superior properties.However,the lower thermal conductivity and the poor heat storage/release characteristics are also huge bottlenecks restricting its development and application.Carbon-based materials are often used as heat conduction additives to enhance the thermal performance of PCM owing to their high thermal conductivity.The effects of carbonbased materials of different dimensions on the heat transfer and heat storage properties of the PCM were reviewed,and summarized the disadvantages of their thermal properties in the research progress.The way forward of the research on the thermal properties of the PCM was pointed out.
