▎ 摘　　要

NOVELTY - A mica plate-based graphene electric heater comprises a metal shell provided with a heating element bracket, and heating element bracket provided with several mica-based heating sheets uniformly arranged. The one end of the metal shell is provided with an air passage channel of electric heater, and a gap is provided between adjacent mica-based heating sheets, and the gap is connected to air passage channel of electric heater. A frequency conversion motor is arranged in the blast channel of the electric heater. The output shaft of the frequency conversion motor is provided with shaft-type cooling blades, and the outer surface of the metal shell is provided with movable shutters. The mica-based heating sheet comprises two upper and lower mica plates, and a graphene heating layer arranged between the opposite sides of the mica plates. USE - Mica plate-based graphene electric heater. ADVANTAGE - The mica plate-based graphene electric heater is economical and energy saving, and has high efficiency and no pollution.
