A novel approachis proposed to enhance the thermal rectification ratio, namely, arranging two thermal rectifiers in series. Through theoretical analysis and molecular dynamics simulations on graphene/phononic crystal structures, the results show that the series thermal rectifiers enhance thermal rectification ratio significantly, compared to a single rectifier. Meanwhile, the results of theoretical prediction match well with simulation results.
提出了一种提高热整流比的新方法,即串联两个热整流器。通过对石墨烯/声子晶体结构的理论分析和分子动力学模拟,结果表明,串联热整流器与单个整流器相比,显著提高了热整流比。同时,理论预测结果与模拟结果吻合较好。
