▎ 摘　　要

NOVELTY - The partitioned electric deicing device has an external icing sensing detection device connected with a partition de-icing control cabinet (1). The partition de-icing control cabinet controls a graphene electro-thermal film (2) to perform single-area electro-thermal de-icing for each heating partition through an electric control switch. The graphene electro-thermal film is fixed in a blade root unit of a fan blade. The graphene electro-thermal film is fixed on a fan blade tip unit that is fixed with a blade front edge and a blade rear edge. The blade front edge and the blade rear edge are connected with each other by a transverse strip-shaped graphene electric heating film. USE - Partitioned electric deicing device for fan blades. ADVANTAGE - Partitioned electric device can realize independent heating of each partition, aiming at the blade freezing characteristics, using targeted heat source arrangement, and using blade vibration, not only reducing the unnecessary energy consumption, but also greatly improving the de-icing efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of partitioned electric deicing device for fan blades.
