NOVELTY - The utility model model claims a mute electric heater, comprising a metal frame, a radiating plate, a graphene mica heating plate, a fixing bolt, a male buckle, a female buckle, a heat-resistant rubber pad and a temperature-resistant adhesive tape, the inner cavity of the metal frame close to the bottom is inserted with a graphene mica heating plate, the side edge of the graphene mica heating plate inserted with the metal frame is sleeved with a temperature-resistant adhesive tape, one side of the graphene mica heating plate is provided with a slot matched and inserted with the radiating plate, the number of the radiating plate is several and are distributed in parallel, one side of the radiating plate close to the upper and lower two ends is provided with a male buckle, the other side of the radiating plate close to the upper and lower two ends is provided with a female buckle matched with the male buckle, each radiating plate is provided with a heat-resistant rubber pad jointed with the side edge, one end of the radiating plate is connected with the opening end of the metal frame through a fixing bolt. The utility model effectively solves the problem of collision abnormal caused by heat expansion of the radiating plate, solves the abnormal sound problem of the metal frame and graphene mica heating plate, and is convenient to maintain.
