Direct drive wind turbine with a thermal control system Abstract 5 A direct drive wind turbine with a thermal control 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 thermal control system (15) comprises a cooling system 10 (16) and a heating system (17). The cooling system (16) com prises at least one heat sink (18) which is in thermal commu nication with the inner ring (6) of the bearing (5) and a heat dissipater (24) which is in thermal communication with the heat sink (18). The heating system (17) comprises at 15 least one heating element (25) being in thermal communication with the outer ring (7) of the bearing (5).
