NOVELTY - The utility model claims a non-contact insulating graphene air electric heater, comprising a ceramic conductive base assembly; the ceramic conductive base assembly comprises an electric joint, heat-conducting insulated sheet and ceramic conductive substrate; the electric joint connected to the two ends of the ceramic conductive substrate; said ceramic electrically conductive substrate assembly is matched and connected with a plurality of heat transfer fins; the heat-conducting insulated sheet conductive base connected with the ceramic. The beneficial effect is that replace existing PTC form conductive ceramic substrate, and the ceramic conductive outer substrate-coating graphene structure, greater use of electric energy is converted into heat energy. the heater is long-term operation is more stable without attenuation.
