NOVELTY - The utility model claims a direct-heated electric heater using graphene, carbon crystal, carbon fibre, comprising an aluminium shell radiating plate, a bracket and an electric heating plate; the electric heating plate adopts heat-conducting profile substrate coated aluminium foil pressing structure, comprising a junction box, a carbon fibre heating wire, a heat conducting substrate; aluminium foil and several binding posts; the junction box is fixed on the heat conducting substrate and connected with the carbon fibre heating wire and the external power supply line; the binding post is fixed on the two sides of the heat conducting substrate; the carbon fibre heating wire is arranged on the heat conducting substrate around the binding post; the aluminium foil is pressed on the carbon fibre heating wire. The utility model optimizes the wiring mode of the wire structure and the electric heating plate clamped in the wiring structure, avoids the cross overlapping of the wire body.
