Generator with vent pipe

Abstract

The invention relates to the field of generators, in particular to a generator with a vent pipe, which is particularly suitable for an automobile generator with small space in a moving state. The generator with the vent pipe comprises a generator body and a cover, wherein the cover is provided with the vent pipe; one end of the vent pipe is communicated with the inside of the generator; and the free end of the vent pipe is an air inlet exposed outside the generator body. The work environment temperature of a diode is greatly improved, the service life is prolonged, and the failure rate is reduced; after the generator with the vent pipe is used in the whole V348 new generation Transit automobile, the test temperature of a position nearby the diode is about 150 DEG C, obvious effect is achieved, and the temperature is reduced by 33.33 percent; the improved generator passes the tests of all parts and the whole automobile, and the problem that the generator fails is quickly solved; and the design is spread to a JMC new project automobile mode test at present.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a generator with a ventilation pipe, especially suitable for motor generators with small space and in a moving state. Background technique [0002] The generator usually adopts the method of opening the cover to dissipate heat, sometimes the heat dissipation effect is not good, and the generator will be burned out. [0003] At the beginning of the high temperature test of the V348 New Era Transit, the diode failed. After the test analysis, the temperature of the generator was too high. The generator at that time referred to the design of generators on the market and European generators, and used the cover to open holes to realize power generation. The engine dissipates heat, and the heat dissipation effect is not good. This is also the disadvantage of the current car generator. Most car generators are installed in the front wheel train of the engine. This position is near the...

[0002]The generator usually adopts the method of opening the cover to dissipate heat, sometimes the cooling effect is not good, and the generator will be burned out

[0003]V348 New Era Transit had a diode failure in the early stage of the high temperature test. After test analysis, the temperature of the generator was too high. The generator at that time was based on the generators and The design of the European alternator uses openings in the cover to realize the heat dissipation of the generator, and the heat dissipation effect is not good. This is also the disadvantage of the current automobile alternator. Most of the automobile alternators are installed in the front wheel train of the engine. Nearby, the temperature is very high, and the ambient temperature in summer can reach about 80 degrees. In addition, after the generator is running, the internal temperature rises rapidly, and the temperature can reach as high as about 190 degrees, or even higher, and the temperature that the diode can withstand is 200 degrees, so When working for a long time, the diode is easy to collapse, and it is urgent to find a solution to the problem
