Abstract

The invention provides a hub ventilation and heat dissipation device. The hub ventilation and heat dissipation device comprises a hub, wherein a wind wheel shaft is fixedly installed at the back side of the hub; an air inlet groove is formed in the windward side of the hub; a gravity offset ring is movably installed in the air inlet groove through an offset bearing; an air inlet hole passing through an S-shaped air inlet channel is formed in the side edge of the rotating axis of the gravity offset ring; an annular air inlet groove is formed in the hub; the air inlet hole communicates with the annular air inlet groove; the annular air inlet groove communicates with a plurality of induced draft ducts arranged in a hub interlayer; an annular air outlet groove matched with the air outlet hole is formed in an air outlet ring; and an air return pipe is fixedly installed at the bottom of the air outlet ring. Through the arrangement of the gravity offset ring and the interlayer ducts in the hub, atmospheric precipitation is effectively prevented from entering the hub, and the interior of the hub is actively cooled through wind energy, so that the energy consumption of equipment is reduced, normal work of connecting parts in the hub is guaranteed, and the heat dissipation effect is improved.

Description

technical field

[0001] The invention relates to the technical field of fan cooling devices, in particular to a hub ventilation and cooling device. Background technique

[0002] In the prior art, the application number is "CN201611141780.7", a cooling system for a wind turbine, a cooling method and a wind turbine. The cooling system includes: a fan, one or more air inlets arranged on the outer wall of the shroud It is installed at the air outlet at the tail of the nacelle cover; the fan is installed at the air inlet, and the air inlet is in front of the hub. The heat dissipation method uses the heat dissipation system, and the wind turbine includes a heat dissipation system. The fan of this technology draws the air outside the wind turbine into the air inlet part, forms a positive pressure airflow in the air inlet part, flows into the windshield, and diverts the air through the windshield and the wheel hub, and respectively separates the upper winding of the engine stator and...
