Title:

SHAFTING COOLING SYSTEM AND METHOD FOR CONTROLLING SAME, AND WIND POWER GENERATOR SET

Document Type and Number:

WIPO Patent Application WO/2019/109612

Kind Code:

A1

Abstract:

Disclosed are a shafting cooling system and a method for controlling same, and a wind power generator set. The cooling system comprises: a cold air supply unit; and a rotating shaft air supply box (19) mounted on an inner surface of a fixed shaft (7) and having a circular ring-shaped box shape, wherein multiple first air supply ports (19a) are uniformly distributed in the circumferential direction on a surface of the rotating shaft air supply box (19) facing a rotating shaft (9) to make cold air from the cold air supply unit blow towards the rotating shaft (9), and each first air supply port (19a) in the multiple first air supply ports (19a) is slit-shaped so as to form a jet. The cooling system realises reliable installation and operation of the cooling system while not affecting the operation of other components in the wind power generator set, and can perform effective heat dispersion on the shafting effectively in a targeted manner, ensuring that the temperature of the shafting of the wind power generator set is within a reasonable working range.
