Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] The utility model provides a kind of generator rectifier bridge structure as Figs. 1 to 3 As shown in the drawing, it includes heat dissipation base 3. Heat dissipation base 3 is circular arc plate-shaped base, and a plurality of studs 9 are fixedly arranged on the extension of heat dissipation base 3 along the circumferential direction. The tail shell 1 of the generator is provided with a plurality of threaded holes. The stud 9 and the threaded hole are one-to-one correspondence, for installing heat dissipation base 3 to the tail shell 1 of the generator.

[0020] The center of the heat dissipation base 3 is located on the central axis of the output shaft 2 of the generator. Meanwhile, a plurality of heat dissipation plates 11 are fixedly arranged inside the heat dissipation base 3, and the plurality of heat dissipation plates 11 are uniformly arranged along the circumferential direction of the output shaft 2 of the generator, and each heat dissipation plate 11 is arranged along the axial direction of the output shaft 2 of the generator. The output shaft 2 of the generator is cooled.

[0021] The thickness of each heat dissipation plate 11 along the circumferential direction of the output shaft 2 of the generator is greater than the thickness of the heat dissipation base 3. For heat conduction.

[0022] A plurality of arc-shaped heat dissipation grooves 5 are formed on the heat dissipation base 3 along the circumferential direction of the output shaft 2 of the generator, and the plurality of arc-shaped heat dissipation grooves 5 are uniformly distributed along the radial direction of the generator 2. Each heat dissipation groove 5 penetrates the heat dissipation base 3 along the circumferential direction of the output shaft 2 of the generator, for air cooling.

[0023] The bottom of each heat dissipation groove 5 is provided with a plurality of arc-shaped heat dissipation holes 10 along the circumferential direction of the output shaft 2 of the generator, and the center of each arc-shaped heat dissipation hole 10 is located on the central axis of the output shaft 2 of the generator.

[0024] The plurality of arc-shaped heat dissipation holes 10 in each heat dissipation groove 5 are uniformly distributed along the circumferential direction of the output shaft 2 of the generator, and each arc-shaped heat dissipation hole 10 penetrates the heat dissipation base 3 along the axial direction of the output shaft of the generator, for air cooling.

[0025] A matching arc-shaped heat dissipation fin 4 is arranged in each arc-shaped heat dissipation hole 10. The heat dissipation fin 4 extends into the heat dissipation groove 5 for heat dissipation.

[0026] The heat dissipation base 3 is provided with a polar plate 6, and the polar plate 6 is connected with the heat dissipation base 3 through a bolt 7 and a nut 8. The bolt 7 is fixedly arranged on the heat dissipation base 3, the polar plate 6 is provided with a through hole corresponding to the bolt 7, and the bolt 7 is threadedly connected with the nut 8 through the through hole.

[0027] The diameter of the through hole is greater than the diameter of the bolt 7, and a non-conductive rubber gasket is arranged between the nut 8 and the polar plate 6. To prevent the heat dissipation base 3 and the tail housing 1 of the generator from being electrified.

[0028] Working principle: when in use, the heat dissipation base 3 is fixed on the tail housing 1 of the generator through the stud 9, and the polar plate 6 is fixed on the heat dissipation base 3 through the bolt 7 and the nut 8. At this time, a plurality of heat dissipation plates 11 are close to the collector ring to increase the heat dissipation area and enhance the heat dissipation.

[0029] When used in high temperature environment, if the multiple heat dissipation plates 11 cannot dissipate the temperature in time, due to the rotation of the output shaft 2 of the generator, the internal gas is disturbed to flow around the circumference of the output shaft 2. At this time, the hot air flows along the inside of the heat dissipation groove 5, thereby taking away the heat that the heat dissipation plates 11 cannot dissipate in time, further enhancing the heat dissipation effect.

[0030] When the hot air flows in the heat dissipation groove 5, it will contact the heat dissipation fins 4 in the heat dissipation groove 5, and the heat dissipation fins 4 can take away the heat in the hot air in time, further effectively dissipating heat.
