▎ 摘　　要

NOVELTY - The element has a positive temperature coefficient (PTC) heating piece (01) whose two sides are electrically arranged with graphene material and a heat radiating body (02). The heat radiating body is provided with an electrode plate (21) and a heat radiating fin (22) that is arranged on a side of the electrode plate. A graphene film is arranged between the PTC heating piece and the electrode plate and connected with a side of the PTC heating piece. The electrode plate is made of copper alloy or aluminum alloy and graphene material. The heat radiating body is made of graphene material. The heat radiating fin is made of copper alloy. USE - Graphene heat-conducting and electricity-conducting PTC heating element. ADVANTAGE - The element has rapid heat dissipation, better heat conducting performance and high coefficient of heat conductivity of the heat radiating body, saves energy, and improves electric heating conversion efficiency and air temperature. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a graphene heat-conducting and electricity-conducting positive temperature coefficient heating element.
