The radial bearing seat 8 of the vortex end is connected to the end plate 4 of the generator shell 1, and the side wall of the radial bearing seat 8 is attached to the outer side wall of the end plate 4; the end cooling channel 5 is additionally arranged in the end plate 4 of the generator shell 1, the end cooling channel 5 is communicated with the main cooling channel 7, cooling liquid in the main cooling channel 7 can be led into the end cooling channel 5, and when the cooling liquid passes through the end cooling channel 5, the cooling liquid exchanges heat with the end plate 4 and the radial bearing seat 8, so that the radial bearing seat 8 and bearing sections on the inner side of the radial bearing seat 8 can be cooled, and the radial bearing seat 8 and bearing sections on the inner side of the radial bearing seat 8 are prevented from being too high in temperature.
Compared with the prior art, the water cooling structure of the turbine generator provided by the utility model has the advantages that the end cooling channel 5 is formed in the end plate 4 of the generator shell 1, and the end cooling channel 5 is communicated with the main cooling channel 7, so that the cooling of the end plate 4, the radial bearing seat 8 and the bearing section can be realized while the generator shell 1 is cooled, and the cooling effect of the water cooling structure of the generator is improved.
Alternatively, the main cooling channel 7 covers the entire generator housing 1 in the axial direction of the generator housing 1, which serves to cool the temperature of the generator housing 1. The end plate 4 is arranged on one side of the generator shell 1 close to the vortex end, and the end plate 4 is welded or connected with a side plate of the generator shell 1 through bolts; the end cooling channels 5 and the main cooling channels 7 formed in the end plates 4 are connected with the side plates of the generator housing 1 by means of the end plates 4 to complete communication, and the effect of sealing the joints is achieved.
Alternatively, the main cooling channels 7 are distributed along the circumferential direction of the generator housing 1, and the depth thereof in the radial direction of the generator housing 1 is smaller than the width thereof in the axial direction of the generator housing 1, so as to ensure the contact area between the main cooling channels 7 and the generator housing 1. The radial bearing seat 8 is attached to the outer side of the end plate 4, and the contact surface of the radial bearing seat 8 and the end plate 4 is perpendicular to the radial direction of the generator housing 1, so that the depth of the end cooling channel 5 along the axial direction of the generator housing 1 is smaller than the radial width of the generator housing 1, and the contact area of the end cooling channel 5 and the radial bearing seat 8 is ensured. By determining the width and depth of the main cooling channels 7 and the end cooling channels 5, the heat exchange area is increased, thereby increasing the heat exchange efficiency.
Furthermore, to ensure heat exchange efficiency, the outer diameter of the end cooling channels 5 is smaller than the outer diameter of the radial bearing blocks 8.

The radial bearing blocks 8 are fixed to the end plate 4 by means of bolts penetrating the seal. At this time, the groove-shaped end cooling channel 5 forms an annular channel with an opening under the action of the water sealing member, so that the direct contact of the cooling liquid with the radial bearing seat 8 can be avoided, and the sealing effect of the end cooling channel 5 is improved.
The cooling liquid can be cooling water or other liquid state cooling medium.

Two second sections corresponding to the two leading-out channels 6, one of which is communicated with the main cooling channel 7, and the other of which is communicated with a water passing port at one side far away from the main cooling channel 7.
