Definitions

  • the invention relates to a wind turbine comprising a tower and a nacelle supported by said tower.
  • the nacelle houses a rotor, and the tower and/or the nacelle includes at least one unit to be cooled.
  • An exchange structure is arranged outside the nacelle and tower and a circuit provides a flow of a fluid medium between the unit and the exchange structure.
  • a wind turbine typically comprises several units which generate excessive heat. Examples of such components are gear boxes, transformers, bearings, generators, and power converters etc.
  • Such units are typically housed in a closed space within the tower or nacelle and heat exchange with the ambient space is limited. Often, active cooling, e.g. by use of a flow of air or a cooling liquid between the units and a heat exchanger, is necessary.
  • One commonly applied cooling structure for electrical components includes a fan for generating air flow around the electrical component or for generating air flow through a heat exchanger coupled to the component.
  • very large wind turbines may include heat exchangers attached outside the nacelle, e.g. fixed to the roof of the nacelle. Since the nacelle is typically actively turned such that the rotor plane is always up against the wind, such roof-mounted heat exchangers also become up against the wind.
  • the heat exchangers are therefore arranged side-by-side facing in one common direction, namely forward with respect to the nacelle and rotor plane.
  • WO-A-0i/006121 discloses a wind turbine with air cooling by use of a tower wall as heat exchanger and US7168251 discloses a liquid cooled wind turbine with heat exchangers arranged outside the tower,
  • the invention provides a wind turbine where a tower mounted heat exchange structure comprises at least one panel having a generally planar shape and defines a plane oriented outwards from the tower.
  • the panel is made with an open structure such that a flow of ambient air can travel transversely trough the panel,
  • the panel can be cooled by air which naturally flows along the outer surface of the tower without the use of artificial, forced air streams, e.g. from a fan or similar powered ventilator means attached next to the panel.
  • the defined plane could be non-parallel to a tangent of the tower such that the panei reaches furthest possible away from the tower and thereby becomes capable of catching natural air flow at a longer distance away from the tower.
  • pane/ means a heat exchanger for exchanging thermal energy between a fluid medium and ambient air and having a primarily two-dimensional shape, i.e. the panel has a largest dimension which is much larger than a corresponding smallest dimension. If the panel is square or rectangular, at least one of the length and height of the panel is much larger than the thickness of the panel.
  • edge of the panel as that side of the panel having the smallest dimension, and the "surface” of the panel is stretched by the other, larger, dimensions of the panel.
  • the plane defined by the panel is oriented substantially in parallel with a vertical, longitudinal axis of the tower.
  • the plane of the panel has a substantially vertical orientation.
  • the largest dimension of the panel could be at least 5 times, such as 10- 100 times larger than the smallest dimension.
  • At least one of the panels “extends outwards from the tower” is herein meant that the panel is arranged with one end of the surface towards the tower and an opposite end of the surface pointing outwards, away, from the tower.
  • the aforementioned edge, at one point, faces the tower, and at another point faces away from the tower.
  • the panel may have a structure corresponding to that of a traditional radiator well known in the art for heating or cooling purposes.
  • the panel may form an open structure, e.g. formed by a plurality of conduits for the fluid medium.
  • the wind turbine according to the invention may comprise at least two, and preferably at least three, or four panels extending in different directions outwards from the tower, e.g. equally spaced about the tower. If four panels are used, they could be located with 90 degrees spacing about the tower. If six panels are used, they could correspondingly be located with 60 degrees spacing about the tower etc.
  • Each panel may comprise an inlet and an outlet for the fluid medium, and the panels may extend in parallel between the inlets and outlets, in this way, the use of the panels may be controlled individually. If certain conditions makes use of selected panels more advantageous than use of other panels, these more advantageous panels may be used exclusively or primarily by reducing the flow to the less advantageous panels.
  • a flow control structure enabling adjustment of flow of the fluid medium through each panel individually may be provided .
  • Such flow control may include valves, e.g. motor controlled valves or valves which are controlled by a thermo element
  • the inlet and outlet may be located in the edge of the panel, e.g. in that portion of the edge facing towards the tower.
  • a passage structure may guide the fluid medium to establish spreading of the thermal energy over the surface of the panel.
  • the fluid medium may be guided in the panel in a direction from the tower and outwards, away from the tower.
  • the individual flow control may be administered individually by a control system dedicated to one specific panel or by a common control system .
  • the control system may adjust the flow based on a control input, e.g. based on an ambient temperature measured outside the tower or nacelle; an ambient wind speed; a wind direction; a temperature of the fluid medium, or other measures relevant for the usage of the panels.
  • At least one, and preferably ail of the panels may be oriented relative to the tower such that they extend radially outwards from the tower. This provides space between the panels and allows a good flow through the panels.
  • At least one of the panels may have a size such that it extends at least one tenth of a tower diameter outwards from the tower, or even one fifth, or one half of a tower diameter outwards from the tower.
  • the panels may be fixed to common frame, e.g. in the shape of a flange extending circumferentiaily about the tower.
  • the frame could be movable along the tower, or it may be rotatabie about the tower until a desired position of the frame, and thus a desired position of the panels relative to the tower, is obtained.
  • the frame may include attachment means for locking the position and thereby obtaining a rigid attachment of the frame to the tower.
  • At least one of the panels could be located at a specific height inside the tower, and at least one of the panels could be located directly outside the tower at that height such that the fluid medium should essentially flow in a horizontal plane or at least primarily flow in a horizontal plane.
  • At least one of the panels could be fixed to the tower by a hinge joint allowing rotation of the panel relative to the tower.
  • the panel may thereby be moved to an orientation by which good flow properties through the panel can be obtained.
  • the panel may include power means for moving the panel relative to the tower, and the power means may be controlled automatically, e.g. based on wind direction, temperatures measured at different locations around the tower, solar incident angle etc.

  • the panel may include adjustment means for expanding the panel, and the adjustment means may be controlled automatically, e.g. based on wind direction, temperatures measured at different locations around the tower, solar incident angle etc.
