Low-noise high-heat-dissipation type automobile alternating-current generator

Abstract

The invention discloses a low-noise high-heat-dissipation type automobile alternating-current generator. The generator comprises a front end cover, a rear end cover, a rotor and a stator. The interior of the front end cover is fixedly connected with one end of the rotor through a front rolling bearing. The interior of the rear end cover is fixedly connected with the other end of the rotor through a rear rolling bearing. A rotating shaft at one end of the rotor penetrates through the front end cover and is fixedly provided with a belt pulley. Stators are fixedly mounted in the front end cover and the rear end cover through O-shaped rings with L-shaped sections. According to the invention, a regulator and a rectifier bridge are moved out of the outer side of the rear end cover, so heat dissipation performance is enhanced; the regulator and the rectifier bridge are wrapped by a cover made of plastic materials, and through effective cooperation of the cover and the first heat dissipation hole, the second heat dissipation hole and the third heat dissipation hole, the heat dissipation performance of the generator is greatly improved; the power generation efficiency of the generator is improved; the service life of the generator is prolonged; and normal operation of the heat dissipation fan during air suction and heat dissipation is guaranteed.

Description

technical field [0001] The invention relates to a generator, in particular to a low-noise and high-radiation automobile alternator, which belongs to the technical field of automobile generators. Background technique [0002] In recent years, the regulations on environmental protection and energy saving have become more and more stringent, and the requirement for future vehicles is to further reduce fuel consumption. On the other hand, customers have higher requirements for comfort. Correspondingly, the power consumption of cars tends to increase. This part of electric energy increases fuel consumption accordingly. In order to provide users with better cars, it is necessary to solve these two conflicting requirements. Therefore, the requirements for the alternator (hereinafter referred to as the generator) are: to improve the conversion efficiency of the generator to convert the engine torque into electric energy; to reduce the volume and quality of the vehicle in order to r...
