| 中文摘要: |
| 由于化石燃料的快速消耗和能源需求的不断增加,如何高效地利用和储存能源变得至关重要。相变材料(PCM)通过固-液相变以潜热的形式储存能量,在热能储存中起着关键作用。石蜡作为一种有机PCM,具有较高的相变潜热、化学惰性和适宜的相变温度等特性,但因本身较低的导热性能以及固-液相变产生的泄露问题限制了其在高热传导领域的应用。针对以上问题,通过现有文献综述了多孔材料吸附、添加高导热纳米颗粒改性以及微胶囊化分别对石蜡导热性能的提升和泄露问题的改善,讨论不同复合方法的优缺点并对石蜡复合PCM的未来发展作出展望。 |
| 英文摘要: |
| With the rapid consumption of fossil fuels and the increasing demand for energy, it is crucial to use and store energy efficiently. Phase change materials (PCM) play a key role in thermal energy storage by storing energy in the form of latent heat through phase transformation. As an organic solid-liquid PCM, paraffin wax has attracted extensive attention due to its high latent heat of phase change, chemical inertness and suitable phase change temperature. However, its low thermal conductivity and the leakage problem caused by solid-liquid phase transformation limit the application of paraffin wax in the field of high thermal conductivity．In order to solve the above problems, the existing literature reviews the improvement of the thermal conductivity and leakage of paraffin wax by adsorption, the modification of nanoparticles with high thermal conductivity and microencapsulation, discusses the advantages and disadvantages of different composite methods, and looks forward to the future development of paraffin composite phase change materials. |
