NOVELTY - The utility model claims a heating piece and skirting line electric heater, the skirting line electric heater comprises a shell, the shell comprises a bottom plate and a top plate arranged at intervals; and a circumferential side plate connected between the bottom plate and the top plate, the bottom plate, the top plate, the circumferential side plate are enclosed to form a containing cavity; the heating piece is set in the containing cavity, and the heating piece is formed with a plurality of convection passages extending along the bottom plate to the top plate direction; at least part of the outer surface of the heating piece is coated with graphene, the circumferential side plate is provided with a radiating hole connected with the containing cavity. in the skirting line electric heater, the air flow realizes natural convection through the convection channel in the vertical direction of the bottom plate to the top plate, and the graphene is coated on at least part of the outer surface of the heating element, the heat radiation of the heating element can be increased, at the same time, the radiating holes opened on the circumferential side plate are used, the heat radiation generated by the heating element is transversely transmitted along the vertical direction vertical to the vertical direction, the skirting line electric heater also can radiate outwards in the transverse direction, increasing the heating range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a heating element.
