Problems solved by technology

[0008] like figure 1 As shown, there is a motor bearing between the motor fixed shaft and the motor rotating shaft of the generator 500'. The motor bearing will generate more heat during the working process, but the motor bearing is surrounded by the motor fixed shaft and the motor rotating shaft. exude
[0009] However, the above solution is mainly to cool the motor core in the generator 500', but there is no suitable cooling solution for the shafting of the generator and the hub

Abstract

The invention discloses a motor, a heat exchange device of a shaft system of the motor and a wind driven generator set. The heat exchange device comprises a flexible cavity. A cooling medium can be fed into the flexible cavity. The flexible cavity is located in the inner wall of a motor rotating shaft and used for cooling a motor bearing in the shaft system of the motor. After the cooling medium is poured into the flexible cavity, the cooling environment can be established on the inner wall of the motor rotating shaft, and therefore a heat dissipation channel is formed for the motor bearing which is arranged between the motor rotating shaft and a motor fixed shaft in an encircled mode, and the good cooling effect is achieved.

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] like 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 pr...
