摘　　要： 对国内外相变材料各种强化传热技术进行了综述与讨论,包括添加金属填料、添加石墨、胶囊封装、加肋片、添加碳纤维和组合相变材料等,展望了相变材料的发展趋势。指出能源的大量消耗使得储热技术的研究越来越重要。其中潜热储热是一种有效的储热系统,相变材料是潜热储热系统的重要组成部分,但是有些相变材料(尤其是一些有机相变材料)存在导热系数低的缺点。在节能越来越受到重视的今天,相变材料的强化传热已成为热点问题。 Ver increasing energy consumption, energy storage techniques are becoming more and more important. It is well known that latent heat storage system （LHTS） is an efficient heat storage system. The phase change materials （PCMs） play an important role in the latent heat thermal storage system. However, some PCMs （especially some organic PCMs） may be limited with low thermal conductivity. Heat transfer enhancement of the PCMs have received great attention as energy saving is becoming more and more important. Various heat transfer enhancement methods are reviewed and discussed, including using metal filler, graphite filler, micro-encapsulation, fins, carbon fibers and multiple change materials. It is reported that the development direction of the PCMs is high thermal conductivity, small weight and low cost.
