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
The present invention relates to technical field of generators, specifically, relate to a kind of generator that has ventilation duct, be particularly useful for the automobile current generator that the space is kept in motion for a short time.
Background technology
Generator adopts the mode of case perforate to dispel the heat usually, and radiating effect is bad sometimes, generator can be burnt out.
The V348 New Times, all-cis car load was at the high-temperature test initial stage, diode fails appears, through analysis of experiments, generator-temperature detection is too high, generator at that time uses the case perforate with reference to the design of generator on the market and European generator, realizes the generator heat radiation, radiating effect is bad, this also is the drawback of present automobile current generator, and automobile current generator mostly is contained in the motor head train, and this position is just near blast pipe, temperature is very high, summer ambient temperature can reach 80 the degree about, add generator operation after, internal temperature rises rapidly, temperature can be up to about 190 degree, even higher, and the temperature that diode can bear is 200 degree, so during long-term work, diode is easy to collapse, is badly in need of finding the way of dealing with problems.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of generator that has ventilation duct is provided, thereby reach the purpose of air-cooled generator, improved the operating ambient temperature of diode greatly, increase the service life, reduce failure rate.
The present invention is particularly useful for the automobile current generator that the space is kept in motion for a short time.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of generator that has ventilation duct comprises generator body and case, has ventilation duct on the described case, and an end of described ventilation duct is connected with generator inside, and the free end of described ventilation duct is to be exposed to this external air inlet of generator.
What described ventilation duct was connected with generator inside one rectifies the generator electronic fan.
The cross-sectional area of described ventilation duct is rectangle or circle or polygon.
Beneficial effect of the present invention is:
1, improves the operating ambient temperature of diode greatly, increased the service life, reduced failure rate.
2, after all-cis car load of V348 New Times adopted the present invention to have the generator of ventilation duct, near the probe temperature the diode was that effect is obvious about 150 degree, and temperature has reduced by 33.33%.Generator after the improvement has passed through all parts and complete vehicle test, has solved the problem of generator failure fast.This design is at present spreaded to again in the vehicle test of Jiangling new projects.
Description of drawings
Fig. 1 is not for the generator external structure schematic diagram of ventilation duct.
One of external structure schematic diagram of the generator that Fig. 2 has a ventilation duct for the present invention is a kind of.
Two of the external structure schematic diagram of the generator that Fig. 3 has a ventilation duct for the present invention is a kind of.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one: referring to Fig. 1, and Fig. 2.
Fig. 1 is not for the generator external structure schematic diagram of ventilation duct.The main ventilation hole 5 that leans on dispels the heat, and radiating effect is not good.
Fig. 2 is a kind of external structure schematic diagram that has the generator of ventilation duct of the present invention.
A kind of generator that has ventilation duct comprises generator body 1 and case 2, has ventilation duct 3 on the described case 2, and an end of described ventilation duct 3 is connected with generator inside, and the free end of described ventilation duct 3 is the air inlet 4 that is exposed to outside the generator body 1.
What described ventilation duct 3 was connected with generator inside one rectifies the generator electronic fan.
The cross-sectional area of described ventilation duct 3 is a rectangle.
When being installed on the automobile, air inlet 4 can make the air intake best results like this towards automobile headstock direction, and radiating effect is best, has improved the operating ambient temperature of diode greatly, increases the service life, and reduces failure rate;
After car load employing the present invention that the V348 New Times is all-cis had the generator of ventilation duct, near the probe temperature the diode was that effect is obvious about 150 degree, and temperature has reduced by 33.33%.Generator after the improvement has passed through all parts and complete vehicle test, has solved the problem of generator failure fast.This design is at present spreaded to again in the vehicle test of Jiangling new projects.
Embodiment two: referring to Fig. 3.The something in common of present embodiment and embodiment one is not given unnecessary details, and difference only is in the present embodiment that the cross-sectional area of described ventilation duct 3 is circular.
Claims (3)
1. generator that has ventilation duct, comprise generator body (1) and case (2), it is characterized in that: have ventilation duct (3) on the described case (2), one end of described ventilation duct (3) is connected with generator inside, and the free end of described ventilation duct (3) is for being exposed to the air inlet (4) outside the generator body (1).
2. a kind of generator that has ventilation duct according to claim 1 is characterized in that: what described ventilation duct (3) was connected with generator inside one rectifies the generator electronic fan.
