Automobile alternating-current generator and application

Abstract

The invention discloses an automobile alternating-current generator, and relates to the technical field of automobile parts. The automobile alternating-current generator comprises a carbon brush mounting base body, a semiconductor chilling plate and a cooling water cavity. The outer wall of the carbon brush mounting base body is fixedly connected with a piston cylinder; a piston plate is connectedto the inner wall of the piston cylinder in an up-and-down sealed sliding manner; the cavity wall of the cooling water cavity, the cylinder wall of the piston cylinder and the plate wall of the piston plate are jointly, vertically, hermetically and alternately connected with a heat dissipation cylinder in a sliding mode; a mercury medium is jointly stored in a cavity formed by the upper surface of the piston plate and the inner wall of the piston cylinder; and the outer wall of the carbon brush mounting base body is fixedly connected with a supporting shaft. By means of good cooperation of the structures, the automobile alternating-current generator has the effects that a single heat dissipation column is replaced with the two heat dissipation cylinders, and when the temperature of any heat dissipation cylinder is too high, the two heat dissipation cylinders can be alternately replaced, and so on, so that on one hand, the heat dissipation effect and efficiency are improved, and on theother hand, the service life of a heat dissipation object is prolonged.

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
