Title:
COOLING SYSTEM, MOTOR, AND WIND TURBINE GENERATING SET
Document Type and Number:
WIPO Patent Application WO/2020/220834
Kind Code:
A1
Abstract:
A cooling system, a motor (100), and a wind turbine generating set. The cooling system is applied to the motor. The motor comprises a stator support (10) and a rotor support (20); the stator support is movably and sealingly connected to the rotor support, so as to form vent chambers (21) at two ends of the motor along the axial direction; the stator support is provided with first vent holes (a) at the two ends along the axial direction. The cooling system comprises: a confluence chamber (102), provided along the periphery of the stator support; an accommodating chamber (101), provided along the periphery of the stator support, the accommodating chamber being located at the inner side of the confluence chamber along the radial direction and communicated with the confluence chamber, and the first vent holes being located outside the accommodating chamber; a heat exchanger (30), provided in the accommodating chamber or in the confluence chamber; and a circulating motor (40), provided along the periphery of the stator support, and located at one side of the stator support along the axial direction, the circulating motor comprising an air inlet (41) and an air outlet (42). After cooled air flows out of the air outlet of the circulating motor, a part of the cooled air enters the vent chamber at the neighboring end, and the remaining cooled air enters the vent chamber at the other end. The cooling system and the motor can implement circulating cooling on a heating component inside the motor. The cooling system has a simple and compact overall structure and occupies a small space. By adopting the motor, the size of a cabin (300) of the wind turbine generating set can be effectively reduced, so that the overall costs and machine loads are reduced, and the reliability and maintainability of the wind turbine generating set are improved.
