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). A method of assembling the modular cooler (24) is also disclosed.

Abstract: Aspects of the present invention relate to a rotor arrangement (42) for a wind turbine generator (24). The rotor arrangement (42) comprises a cylindrical ring structure (46) arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises: a plurality of ring-shaped permanent magnet packages (48) arranged coaxially around the rotational axis, a plurality of tie rods (55) extending axially through the plurality of permanent magnet packages (48) to join the plurality of permanent magnet packages (48) together; and one or more spacer components (64; 164) located between at least one axially adjacent pair of the plurality of permanent magnet packages (48) to space the respective pair of permanent magnet packages (48) apart, wherein the one or more spacer components (64; 164) are configured to act as an impeller as the rotor rotates, in use, thereby to cause air to flow in a radial direction, with respect to the rotational axis of the rotor arrangement (42), between the at least one axially adjacent pair of permanent magnet packages (48). The generator rotor arrangement uses a portion of the kinetic energy of the rotating rotor arrangement to generate a radial air flow that flows between and/or around the magnet packages to transfer heat away from the magnet packages, and thereby to provide a cooling function.
