▎ 摘　　要

NOVELTY - The heater has a heater body provided with a strip-shaped or annular or arc-shaped conductor (1) and a heating body (3). The conductor is provided with a power supply connector. The heating body is arranged between two adjacent intervals. The conductor is provided with a heat radiating fin (2). A graphene layer (5) is sprayed on a partial surface of the heat radiating fin. A graphene fin is extended from an end of the heating body to an end away from the heating body on the heat radiating fin. A power supply connector (4) is provided between the heating bodies, where the heating body is a ceramic sheet heating body. USE - Graphene positive temperature coefficient (PTC) heater. ADVANTAGE - The heater effectively increases heat conduction capability of the heat radiating fin and the graphene layer so as to improve heating efficiency of the heater body to air flow and quickly uniformly transmits heat of the end of the heating body to a radiator far away from an end of the heater body. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a graphene PTC heater. 1Conductor 2Heat radiating fin 3Heating body 4Power supply connector 5Graphene layer
