A kind of automobile alternator and its application

Abstract

The invention discloses an automobile alternator, which relates to the technical field of auto parts, and comprises a carbon brush mounting seat body, a semiconductor refrigerating sheet and a cooling water cavity. A piston cylinder is fixedly connected to the outer wall of the carbon brush mounting seat body, and the piston The inner wall of the cylinder is sealed and slidably connected up and down with a piston plate, the cavity wall of the cooling water chamber, the cylinder wall of the piston cylinder and the plate wall of the piston plate are jointly connected with a radiating cylinder in an alternately up and down sealing and sliding connection, and the upper part of the piston plate The surface and the cavity formed by the inner wall of the piston cylinder jointly store the mercury medium, and the outer wall of the carbon brush mounting seat body is fixedly connected with a support shaft. Through the good cooperation between the above-mentioned structures, the present invention has the ability to replace a single heat dissipation column with two heat dissipation cylinders, and when the temperature of any one of the heat dissipation cylinders is too high, the two heat dissipation cylinders can be replaced alternately. On the one hand, the effect and efficiency of heat dissipation are improved, and on the other hand, the effect of prolonging the service life of the heat dissipation object.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automotive alternator and its application. Background technique [0002] For example, the Chinese patent CN201910367710.0 discloses an environment-friendly automotive generator regulator bracket. The invention includes a carbon brush mounting base body. Two mounting holes are provided on the front side of the carbon brush mounting base body. The groove body and the body of the carbon brush mounting seat are also provided with a strip-shaped heat dissipation chamber. The length of the heat dissipation chamber extends up and down. The heat dissipation chamber is located between the groove body and the installation hole. Two and respectively facing the two installation holes, the upper hole wall of the installation hole is provided with an exhaust hole that connects the installation hole with the corresponding heat dissipation chamber, and semiconductor refrigeration chips are...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of automobile alternator and its application, possessed by replacing a single heat dissipation column with two heat dissipation cylinders, and after the temperature of any one heat dissipation cylinder is too high, the two heat dissipation cylinders can be replaced alternately, so Reciprocation, on the one hand, improves the effect and efficiency of heat dissipation, on the other hand, prolongs the effect of the service life of the heat dissipation object, and solves the problem of cooling the hot surface of the semiconductor refrigeration sheet by using a single heat dissipation column in the prior art, and then cooling the semiconductor refrigeration sheet When the temperature of the hot surface is too high, because the single heat dissipation column is always in contact with the hot surface of the semiconductor cooling sheet, the single heat dissipation column is always in an overheated state, and it is difficult to dissipate the heat, which will easily affect the service life of the heat dissipation column after a long time
