NOVELTY - The utility model claims a PTC radiator (10) with graphene plating layer and a fan heater, the PTC radiator comprises: the metal substrate (11), the PTC heating element (12), the inner radiating fin (13) and the outer radiating fin (14) metal substrate (11) are annular, and the surface of the metal substrate is formed with graphene plating layer, the PTC heating element (12) is annular, the PTC heating element (12) is set on the metal base plate, the inner radiating fin (13) is set along the inner circumference of the annular metal base plate (11), the outer radiating fin (14) is set along the outer circumference of the annular metal base plate (11). by setting the PTC radiator with a circular graphene, so that the heating element is matched with the common air channel size in the market so as to reduce the flow dead zone; by setting the inner and outer radiating fins of the high radiation rate graphene the plating layer, enhancing the heat transfer efficiency of the PTC heating element. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a heater unit comprising the PTC radiator.
