Abstract: A wind turbine with a tower; a nacelle supported by said tower; at least one unit to be cooled and arranged in the tower or the nacelle; a tower mounted heat exchange structure arranged outside the nacelle and tower; and a circuit facilitating a flow of a fluid medium between the at least one unit and the heat exchange structure. To improve thermal convection with the ambient space, the heat exchange structure comprises a set of panels mutually angled and extending outwards from the tower such that a flow of ambient air can pass transversely trough the panels and thereby cool the unit.
