Abstract

The invention discloses a heat exchange device for a motor and its shaft system, and a wind power generator set. The heat exchange device includes a flexible cavity capable of inputting a cooling medium, and the flexible cavity is located on the inner wall of the motor shaft. The flex chamber cools the motor bearings in the motor shaft. After the cooling medium is injected into the flexible cavity, a cooling environment can be established on the inner wall of the motor rotating shaft, thereby opening up heat dissipation channels for the motor bearings enclosed between the motor rotating shaft and the fixed shaft of the motor, and achieving a better cooling effect.

Description

technical field

[0001] The invention relates to the technical field of cooling of electrical equipment, in particular to a heat exchange device for a motor and its shaft system, and a wind power generator set. Background technique

[0002] Please refer to Figure 1-2 , figure 1 The joint diagram of the whole machine for cooling the inside of the generator by the air partition wall heat exchanger; figure 2 for figure 1 Schematic diagram of the structural decomposition of the intermediate wall heat exchanger.

[0003] Such as figure 1 As shown, the right side of the generator 500' is connected to the impeller 600', the left side is provided with a nacelle 100', and a partition wall heat exchanger 300' is arranged in the nacelle 100', specifically at the tail of the nacelle 300'. The left side of the partition wall heat exchanger 300' is provided with an internal circulation induced draft fan 202', which is driven by an internal circulation drive motor 201', and is also...
