Title:
COOLING DEVICE, MOTOR AND WIND TURBINE GENERATOR SET
Document Type and Number:
WIPO Patent Application WO/2020/220836
Kind Code:
A1
Abstract:
The present application relates to a cooling device, a motor and a wind turbine generator set. The cooling device is integrated inside the motor and comprises: a box, being extending along the axis of the motor, wherein the box has an accommodating chamber, as well as an air inlet and an air outlet communicating with the accommodating chamber, and the box communicates with the inside of the motor through the air inlet and communicates with ventilation chambers located at two axial ends of the motor through the air outlet; a heat exchanger, being located in the accommodating chamber and arranged close to the air outlet; and a circulation fan, being arranged in the accommodating chamber along the axial direction of the motor. The modular design of the cooling device can be realized by arranging the heat exchanger and the circulation fan in a box that extends along the axial direction of the motor, and thus the cooling device has a simple and compact structure and occupies small space.
