摘要
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 had large latent heat and very wide phase-transition temperature, no supercooling, low cost andwas stable, nontoxic and not corrosive. However, paraffin waxes suffered from a low thermal conductivity and liquid leakage when they undergone the change of solid-liquid phase. So far, paraffin was taken as the most promising phase change mate- rial. Emphasis was put on the recent development concerning the solutions of thedisadvantages of phase change materials （PCM）, and the prospective developments in PCM were anticipated.
