改善定形相变材料导热性能的实验研究

Experimental study on improving thermal conductivity of shaped-stabilized phase change materials

定形相变材料的发展给予了建筑节能和储能领域新的出路,相变材料的导热性能是储能研究的关键问题之一,现有相变材料导热系数较低,经济有效地改善定性相变材料的导热性能是值得深入研究的热点问题。本文通过掺混不同粒径的沙子、土壤,实验结果表明所采取的掺混方法均在不同程度上明显的改善了相变材料的导热性能。

The development of shape-stabilized phase change materials has given a new outlet to the field of building energy conservation and energy storage. The thermal conductivity of phase change materials is one of the key problems in energy storage research. In this paper, sand and soil with different particle sizes are mixed, and the experimental results show that the mixing methods adopted have significantly improved the thermal conductivity of the phase change materials to different degrees.
