Process for de-icing a rotor blade of a wind turbine and rotor blade suitable for carrying out the process

摘要

In order to de-ice a rotor blade of a wind driven power station with communicating cavities (9, 10), an optionally preheated heat-transfer fluid is passed through the cavities by means of electric fans. Near the root of the blade, where the blade is connected to the rotor hub, means are provided for making the heat-transfer fluid flow into at least one cavity (9) located along the leading edge of the blade. Heat-transfer fluid flow channels that interconnect adjacent cavities are arranged at the blade-tip end (12) of the chambers.
