▎ 摘　　要

NOVELTY - The device comprises a heating layer (2), a heat transfer layer (3) and a packaging layer (4). The heating layer, the heat transfer layer and the packaging layer are orderly arranged from inside to outside, and as a single external whole attached on a blade base (1) front edge. The single outer shape is the same as that of blade base. The material of the heat transduction layer is a woven structure of a compound material graphene, the heating layer is provided with multiple resistance wires, and the material of packaging layer is glass-fiber compound material. USE - Wind turbine blade anti-deicing device useful for in-service wind turbine blade used in wind power generation, and used in other types of wind turbines. ADVANTAGE - The device adopts heating, heat transfer and packaging unit, which realizes the lifting of wind turbine blade/de-icing heating efficiency, improves the efficiency and energy utilization rate of the blade for preventing/removing ice. The device adjusts the position of the electric heating device and the arrangement density of the resistance wire to ensure the blade tip region heating efficiency. The graphene-based compound material improves the heat transfer capability of the compound material, improves electrothermal anti-de-deicing heat transfer efficiency, reduces the energy consumption, and reduces the intensity and weight of the device. The resistance wire of all the groove width along the blade substrate spreading direction is reduced, at the same time, the density of bending part is increased along the tip direction, and the tip end position density is the largest. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a wind turbine blade. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing a central section of an Wind turbine blade anti-deicing device.
