NOVELTY - The utility model claims a ground heating device provided with graphene intelligent heating film, comprising a first cement layer, one side of the first cement layer fixedly connected with a second cement layer, the top of the first cement layer fixedly connected with with a first insulating plate, the top of the second cement layer fixedly connected with a second insulating plate; the top of the first insulating plate fixedly connected with with a first graphene heat film; the utility model is provided with a graphene heat film between the second heat insulating plate and the second insulating plate; the graphene heat film is flatly paved on the top of the second insulating plate; because the graphene heat film itself has strong conductivity, after the graphene is electrified; the total conversion rate of the effective electric heating energy is more than 99 %; at the same time, adding special superconducting property, ensuring the stability of the heating performance; compared with the conventional intelligent heating film, graphene heat film heating stable, safety improves the heat transfer efficiency of the ground heating, reduces the heating power consumption and is more environment-friendly.
