Abstract

The invention discloses a double-channel heat dissipation generator, and belongs to the field of generators. An iron core body, a left fan and a right fan are arranged on a shaft body. The iron core body is positioned between the left fan and the right fan; the outer wall of the iron core body is provided with a plurality of axially distributed wire slots; the winding wire is wound on the wire slot of the iron core body; the top of the wire groove is provided with a groove block used for sealing the wire groove. A left fixed cover covers the left end of the iron core body, and a right fixed cover covers the right end of the iron core body; the left fixing cover and the right fixing cover each comprise an air inlet end face and an air outlet side face. The left fan is used for pressing air flow from the air inlet end face of the left fixing cover and pressing the air flow out from the air outlet side face of the right fixing cover; and the right fan is used for pressing air flow from the air inlet end face of the right fixing cover and pressing the air flow out from the air outlet side face of the left fixing cover. According to the double-channel heat dissipation generator, the rotating body is provided with the double channels in the length direction, heat dissipation is not interfered with each other, the heat dissipation capacity is adjustable, heat dissipation of the double channels is complementary, heat dissipation of the rotating body is uniform, and the service life of equipment is long.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a dual-channel heat dissipation generator. Background technique [0002] A known principle of a large-scale generator, the winding of the rotating body is wound on the slot of the iron core of the rotating body, and after the winding of the rotating body is connected to direct current, when the rotating body rotates as a whole, a rotating magnetic field is formed . The U, V, and W three-phase windings in the stator core cut the magnetic field in sequence, and induce an electromotive force in the stator windings. [0003] In the existing generator heat dissipation method, after the high-pressure fan of the generator is pressurized, the cold air is combined to ventilate and dissipate heat in the direction parallel to the shaft and perpendicular to the shaft. The air holes are complex and there is interference between the air flows. The wind loss is large. Even so,...
