  • Patent number: 10920742
    Abstract: A noise-reduction device for a wind turbine and the wind turbine applied thereof are introduced. The noise-reduction device has a body. The body has a connection portion and a spoiler. The connection portion is concavely disposed on one side of the body and corresponds in shape to the wind turbine's blade so as to be fixed to a confronting edge of the wind turbine blade. The spoiler is disposed on the opposing side of the body. As soon as the wind turbine blade is driven by wind, the spoiler stirs air and guides the air across two sides thereof. When guided by the spoiler, airflows turn into vortexes on the wind turbine blade; hence, the chance that the wind turbine will stall and generate noise is greatly reduced.
