Dual channel cooling generator

Abstract

The invention discloses a dual-channel heat dissipation generator, which belongs to the field of generators. An iron core body, a left fan and a right fan are arranged on the shaft body; the iron core body is located between the left fan and the right fan; Axially distributed wire grooves; the wire is wound on the wire groove of the iron core; the top of the wire groove is provided with a groove stopper for closing the wire groove; the left end of the iron core is covered with a left fixed cover, and the right end is covered with a right fixed cover; Both the left fixed cover and the right fixed cover include the air inlet end face and the air outlet side; the left fan is used to press the air flow in from the air inlet end face of the left fixed cover, and press out from the air outlet side of the right fixed cover; The air inlet end face of the right fixed cover is pressed into the air flow, and pressed out from the air outlet side of the left fixed cover. In the dual-channel heat dissipation generator of the present invention, the rotating body has two channels in the length direction without interfering with each other to dissipate heat, the heat dissipation capacity is adjustable, and the dual-channel heat dissipation is complementary, so that the heat dissipation of the rotating body is uniform and the service life of the 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,...
