In order to study the effect of micron particle fillers on the thermal conductivity of filled type high thermal conductive composites, we constructed a finite element model of composites with randomly distributed particle fillers in this study. The effects of filling ratio, particle size, thermal conductivity, particle shape of filler on the thermal conductivity of the composites were calculated and discussed, respectively. The results show that with the increase of filling ratio and length-to-diameter ratio of filler particle, the thermal conductivity of the composites increases significantly. The particle filler size has little effect on the thermal conductivity without considering the interface thermal resistance and particle agglomeration. The thermal conductivity of filler has little effect on the thermal conductivity of the composites. Without considering the interface thermal resistance, whether the heat conduction channel can be formed effectively is the key to determine the thermal conductivity of the filled type composites.
