DIRECT DRIVE WIND TURBINE WITH A COOLING SYSTEM

摘要

A direct drive wind turbine with a cooling system (15) has a generator (11) with a rotor (12) and a stator (13) and a bearing (5) with an inner ring (6) and an outer ring (7) connecting the rotor (12) and the stator (13) rotatively. The cooling system (15) comprises at least one heat sink (16) which is in thermal communication with the inner ring (6) of the bearing (5) and a heat dissipater (21) which is in thermal communication with the heat sink (16).
