石蜡具有相变潜热高,相变温度范围宽,无过冷现象,低廉稳定性好,无毒无腐蚀的优点,但存在着导热性差,固液相变时存在渗漏等缺点。目前石蜡已经是最为广泛的一类材料,具有很好的应用前景。论述了解决石蜡基相变材料两大缺点的方向,并展望了石蜡基相变材料的发展趋势。 Paraffin wax has the advantages of high phase transition latent heat, wide temperature transformation range, no subcooling, low stability, non-toxic and non-corrosive. However, paraffin has some disadvantages such as poor thermal conductivity and leakage during solid-liquid phase transition. At present, paraffin is the most widely used type of material and has good application prospects. The directions of solving the two shortcomings of paraffin-base phase change materials are discussed. The development trend of paraffin-base phase change materials is also forecasted.
