| 摘 要： | 利用膨胀石墨的层状结构及其高热导率制备了膨胀石墨/石蜡复合相变储能材料。采用层状复合材料的热传导模型,通过ANSYS软件对膨胀石墨/石蜡复合相变材料的相变过程进行数值模拟。结果表明,与纯石蜡相变材料相比,膨胀石墨/石蜡复合相变材料中加入膨胀石墨的强化传热性能效果很显著。

| Abstract: | With the layered structure and high heat conductivity of expanded graphite,phase change materials of expanded graphite/ paraffin wax were compounded.With the use of the heat transfer model of layered composites,the phase change of the phase changes materials of expanded graphite/ paraffin wax were simulated by ANSYS.The results show that compared with the pure paraffin wax phase change materials,the heat performance of the phase change materials of expanded graphite/ paraffin wax is significant. |
