▎ 摘　　要

NOVELTY - The heater has a radiator frame (5) whose lower end is provided with a cavity. The cavity is filled with superconducting liquid. Multiple superconducting heating sheets (4) are inserted into the superconducting liquid at the lower end. The superconducting liquid is heated by a graphene (2). The graphene is connected with the power supply through a lead wire (1). The superconducting heating sheet is filled with superconducting liquid. USE - Graphene superconductive electric heater. ADVANTAGE - The energy utilization rate is improved. The cost is reduced. The heat loss is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the graphene superconductive electric heater. Lead wire (1) Graphene (2) Superconducting liquid (3) Superconducting heating sheets (4) Radiator frame (5)
