Generator with vent pipe

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 J
