A wind energy turbine includes a tower, a nacelle rotatably supported by
the tower, a rotor rotatably supported by the nacelle, and at least one
unit to be cooled and arranged in the tower and/or the nacelle. The unit
is adapted to be cooled by a cooling medium flowing in a cooling circuit
from the unit to at least one heat exchanger. The at least one heat
exchanger is located outside of the tower and/or nacelle and configured
to be cooled by ambient air.
