  • Publication number: 20240102454
    Abstract: A wind turbine (10) includes a nacelle (14) with a longitudinal axis (LA) aligned with the flow of the incoming wind during operation. When so aligned, the nacelle defines a longitudinal direction (X). The wind turbine (10) includes one or more heat-generating components (22) and a modular cooler (24) operatively coupled to the one or more heat-generating components (22). The modular cooler (24) includes one or more cooling modules (30) with each including one or more cooling units (32). Each cooling unit (32) includes a heat exchanger (40) defining a cooling area (38), which defines a normal axis (NA) and a deflector plate (42) to divert the flow of the incoming wind by an angle less than 180° relative to the longitudinal direction (X). Each cooling unit (32) is oriented such that the normal axis (NA) is non-parallel to the longitudinal axis (LA). The modular cooler (24) is scalable in multiple dimensions to increase the cooling capacity of the cooler (24).

  • Publication number: 20230258153
    Abstract: A method of yawing a nacelle in a wind turbine having a yawing assembly comprising a drive-ring and a plurality of drives configured to exert a torque during movement along the drive-ring and thereby move the nacelle relative to the tower. The drive-ring is made of drive-ring segments joined in intersections. The method comprises defining a location for each intersection, defining a reference torque exerted by the drives when moving along the drive-ring, defining a reduced torque being lower than the reference torque, determining when a crossing drive moves across the location of an intersection, and to increase the lifetime, exerting the reduced torque by the crossing drive.
