相变热界面材料研究进展

Research Progress of Phase Change Thermal Interface Materials

相变热界面材料是一种通常为固态但超过一定温度时吸热熔融成液态防止继续升温并充分润湿热传递界面加强传热的新型热界面材料。相变热界面材料综合了导热膏的高填充性及导热垫片的无溢出性的优点,在近年来得到积极开发与应用。主要介绍相变热界面材料的分类、结构设计、导热性能改善等研究现状,并对研究现状提出展望。

Phase change thermal interface materials are usually in the form of solid. But when above a certain temperature, it will be the molten liquid, which can prevent heating up and fully wet the interface to strengthen heat transfer. Phase change thermal interface materials have the both advantages of the high thermal conductive paste and thermal conductive gasket with a positive development and application in recent years. Herein, an introduction about the classification of phase change thermal interface materials, structural design, performance improvement of thermal conductivity is presented. The research status and prospect to the research status are put forward.
