Research Progress in Improving Thermal Conductivity of Paraffin PCM

In recent years,paraffin as a phase change material received more attention.Thermal conductivity of paraffin phase change materials is low,which leads to low effective rate of heat of the energy storage system during storing and releasing thermal energy,the heat can't be stored and released quickly and efficiently.Therefore,improving thermal conductivity of paraffin phase change materials become a research emphasis.In this paper,the research situation of improving thermal conductivity of paraffin phase change materials at home and abroad were summarized from several aspects,such as fin structure,multiple phase change materials,composite phase change materials and microencapsulated phase change materials.
