▎ 摘　　要

NOVELTY - The wallboard has an outer substrate (1) whose end is fixedly connected with a concave foam plate (2). An inner surface of the concave foam plate is fixedly connected with a graphene heating layer (3). A side of the concave foam plate is fixedly connected with an inner substrate (5) far away from the outer substrate. The inner substrate and the concave foam plate are fixedly connected with an A-shaped frame plate (4). An end of the graphene heating layer is fixedly connected with an elastic bag layer (6). A flow control cone is fixedly connected with the inner substrate through the elastic bag layer. USE - Assembled graphene heating wallboard. ADVANTAGE - The wallboard maintains heat flow between the concave foam plate and the inner base plate in the violent flow, balances the heat distribution of the region, accelerates the heat emitted by the inner substrate to the outside and effectively improves the radiating effect. DESCRIPTION OF DRAWING(S) - The drawing shows a side sectional view of an assembled graphene heating wallboard.
