    Abstract: A heat-conductive dielectric polymer material includes a thermosetting epoxy resin, a nonwoven fiber component, a curing agent and a heat-conductive filler. The thermosetting epoxy resin is selected from the group consisting of end-epoxy-function group epoxy resin, side chain epoxy function group epoxy resin, multi-functional epoxy resin or the mixture thereof. The thermosetting epoxy resin comprises 4%-60% by volume of the heat-conductive dielectric polymer material. The curing agent is configured to cure the thermosetting epoxy resin at a curing temperature. The heat-conductive filler comprises 40%-70% by volume of the heat-conductive dielectric polymer material. The nonwoven fiber component comprises 1%-35% by volume of the heat-conductive dielectric polymer material. The heat-conductive dielectric polymer material has a thermal conductivity greater than 0.5 W/mK.
