Embodiment 1
[0035] see figure 1 and figure 2 , a method for improving the uniformity of stator axial temperature distribution, comprising the following steps:
[0036] a. Install the stator axial temperature distribution uniformity device on the wind turbine;
[0037] b. Install stator pressure plate one 5, stator pressure plate two 6, axial ring plate 8, circumferential ring plate 11 and stator core 4 of the stator axial temperature distribution uniformity device, and place the circumferential ring plate 11 and axial ring plate 8 between The included angle is set at 85°, forming a space 13 at the back of the stator core;
[0038] c. The airflow flowing through the back space 13 of the stator core is set so that the airflow flowing through the stator-rotor gap 12 has the same flow rate and the opposite flow direction at the same axial position.
