Problems solved by technology

[0002] When the car moves at high speed, it will drive the generator to rotate quickly, which will generate high heat inside the generator. Since the rectifier bridge bracket of the car generator is installed inside the generator, the high temperature generated by the high-speed rotation of the generator will cause The generator rectifier bridge bracket inside the generator is hot. If the heat of the generator rectifier bridge bracket cannot be dissipated in time, it will damage the generator rectifier bridge bracket and affect the normal use of the generator.

Embodiment 1

[0032] see Figure 1-Figure 7 , the present embodiment proposes an automobile alternator with a sound-absorbing ring structure, including a generator 7 fixed on the bottom plate 8, a rectifier bridge support body 11 is installed inside the generator 7, and an end cover on the top of the generator 7 A sound-absorbing ring 6 is connected, and the sound-absorbing ring 6 effectively reduces the noise caused by the operation of the generator 7 .

[0033] The cooling water tank 1 is fixed on the base plate 8, the top of the cooling water tank 1 is welded with a sealing box 2, the inside of the cooling water tank 1 is formed with a water storage tank 24, and the inside of the sealing box 2 is formed with a cavity communicating with the water storage tank 24, the water storage tank The front and rear width of 24 is identical with sealed box 2 interior front and rear widths.

[0034] The center of the inner cavity of the sealing box 2 is rotatably connected with a rotating shaft 21, a...

Embodiment 2

[0047] see image 3 as well as Figure 8-Figure 15 , the present embodiment proposes an automobile alternator with a sound-absorbing ring structure, which adopts the same inventive concept as that of Embodiment 1, and the difference between it and Embodiment 1 is that the rotating shaft 21 in this embodiment is Hollow structure, its internal rotation is connected with a hollow tube 33, there are a number of through holes on the rotating shaft 21, the two ends of the hollow tube 33 are fixed on the inner walls on both sides of the sealing box 2, the first one-way valve 10 in this embodiment is arranged on One side of the sealing box 2 is located at the center and communicates with the hollow pipe 33 in the rotating shaft 21 . The side wall of the hollow tube 33 is provided with a number of through holes towards the direction of the water storage tank 24. The inside of the rotating plate 20 is hollow to form a liquid inlet tank 31. The through holes provided on the rotating sha...

Abstract

The invention discloses an automobile alternating-current generator with a silencing ring structure and a heat dissipation method thereof.The automobile alternating-current generator comprises a generator body fixed to a bottom plate, a rectifier bridge support body is installed in the generator body, a silencing ring is connected to an end cover on the top of the generator body, a sealing box is welded to the top of a cooling water tank, and a water storage tank is formed in the cooling water tank; a cavity communicated with the water storage tank is formed in the sealing box, a rotating shaft is rotationally connected to the center of the cavity, a plurality of rotating plates are annularly connected to the circumferential surface of the rotating shaft in a sleeving mode, each rotating plate is arranged in the sealing box in a sealed mode, and when rotating to the water storage tank, each rotating plate can disturb cooling liquid in the water storage tank. When the rotating speed of the generator is low, the generator is cooled through the cooling fan and external cooling liquid circulation, when the generator rotates at a high speed, the cooling liquid cools the rectifier bridge support body from the inside at the same time, and the cooling effect is better through triple cooling.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of automobile generators, and in particular relates to an automobile alternator with a muffler ring structure and a heat dissipation method thereof. Background technique [0002] When the car moves at high speed, it will drive the generator to rotate rapidly, which will generate high heat inside the generator. Since the brackets of the rectifier bridge of the car generator are installed inside the generator, the high temperature generated by the high-speed rotation of the generator will make the The generator rectifier bridge support inside the generator is hot. If the heat of the generator rectifier bridge support cannot be dissipated in time, it will damage the generator rectifier bridge support and affect the normal use of the generator. Contents of the invention [0003] The object of the present invention is to provide an automobile alternator with a sound-absorbing ring structure ...
