NOVELTY - The utility model claims a high power graphene PTC air heating heater. It comprises a flat pipe with a built-in heating element, a plurality of heating cores composed of radiating structures installed at two sides of the flat pipe, and a mounting frame for mounting each heating core, the radiating structure of each heating core comprises an aluminium frame and a radiating fin set in the aluminium frame and composed of multiple sections of aluminium belt bending section bent repeatedly, each section of aluminium belt bending section is provided with a radiating window and the outer surface of the radiating fin is coated with a graphene coating. After using the structure, it can obviously improve the heat exchange efficiency under a certain heating power condition, at the same time, the graphene coating coated on the outer surface of the radiating fin can release the far infrared ray, it is good for the safety and anti-aging of the product, it further improves the radiating efficiency and is beneficial to the human body.
