摘要

导热系数低是影响相变储热材料应用的主要难题之一，而泡沫金属具有高热导率、高孔隙率以及高比表面积等特性，在相变材料中添加泡沫金属可实现强化传热。该文基于泡沫金属基3D微观结构W-P模型，重点分析了泡沫金属基复合相变材料有效导热系数与泡沫金属孔隙率以及孔径的关系，采用数值模拟方法利用该模型预测并验证了泡沫铝6101添加空气与水的有效导热系数，研究结果表明该模型能够精确预测泡沫金属材料有效导热系数，在此基础上预测了石蜡中添加泡沫铜的有效导热系数，结果表明，泡沫金属可以显著提高相变材料的导热系数，当泡沫铜的孔隙率为97.57%时，复合相变材料的导热系数与纯石蜡相比提高了13倍。研究结果对于相变储热材料的热物性强化研究具有一定参考价值。

Abstract

The low thermal conductivity for most of phase change materials is one of main obstacles in real application. Foam metals can be added into the phase change material to strength heat transfer process because of high thermal conductivity

high porosity and high specific surface area of foam metals. Based on the 3D W-P micro structure model of foam metal

the effect of porosity and pore diameter of foam metals on effective thermal conductivity of the foam metal based composite phase change materials were analyzed. The numerical simulation method was used to predict the thermal conductivity of foam aluminum-air and foam aluminum-water composites.The results show that the W-P model can be used to precisely predict the thermal conductivity of foam metals. The effective thermal conductivity of foam copper-paraffin composite was then analyzed. It is shown that the thermal conductivity of phase change material can be enhanced greatly by adding foam metals

and the thermal conductivity of paraffin has been increased 13 times when the porosity of foam copper is 97.57%. This study has reference value for thermophysical properties enhancement research on phase change materials.
