Abstract
The utility model discloses an alternating current generator shell which can change the acquisition position of an alternating current generator cooling air and definite the best cooling air leading-in position with actual conditions of the alternating current generator on a full carload thereby guaranteeing the best cooling ways of the alternating current generator on the actual full carload conditions and improving the heat emission function of the alternating current generator and then extending the service life of the alternating current generator. The utility model at least comprises a sealed shell body and a wind-guiding canal which is extended from the shell body, wherein the shell body is fixed on a motor, while an air inlet position of the wind-guiding canal can be set with requirements.
Description
Technical field
The utility model relates to a kind of motorcar alternator part, relates in particular to a kind of alternating current generator case.
Background technology
Alternating current generator is built-in double fan three phase rectifier form substantially at present, and the heat radiation of alternating current generator is by former and later two fans on the alternator rotor, forms air stream, dispels the heat by air transmitted.When alternating current generator is worked, suck air by the axial front and rear portions of alternating current generator respectively, through the alternative electric generation machine part, by alternating current generator blow out air radially.
The alternating current generator case is according to the alternating current generator concrete form at present; adopt suitable form to prevent that foreign matter from entering alternating current generator inside; the effect of protection alternative electric generation machine part; as shown in Figure 1; have a lot of little ventilating openings 11 above the case 10, ventilating opening 11 is over against the direction at axial rear portion, and inhaled air enters the axial rear portion of engine through ventilating opening 11; because opening is less, can prevent that like this foreign matter from entering engine interior.In some car load utilizations, because the layout of car load engine, alternating current generator position in the car load enging cabin is improper, and axially the rear portion is near high temperature parts such as waste pipes, though can take the thermal insulation board device when car load is arranged, effect is bad.Alternating current generator is when work, inhaled air heated by the car load high-temperature component and alternating current generator parts temperature gap little, the air transmitted radiating effect is poor, can't satisfy the heat radiation needs of alternating current generator, therefore can cause the alternating current generator output performance to descend, can't satisfy car load electricity consumption requirement, the alternating current generator parts damage fast, serious meeting makes the alternating current generator temperature rise too high, cause the short circuit of alternating current generator parts, initiation fire causes life and property loss.
The utility model content
The utility model provides a kind of alternating current generator case, it can change the collection position of alternating current generator cooling air, determine that according to the actual state of alternating current generator on car load best cooling air imports the position, thereby guarantee that alternating current generator has the best type of cooling under actual whole vehicle state, improved the heat sinking function of alternating current generator, and then improved the life-span of alternating current generator.
In order to solve above technical problem, the utility model provides a kind of alternating current generator case, it at least by the sealing shroud body and on described shroud body extended wind-guiding pipeline form, described shroud body is fixed on the alternating current generator, and the position of the air intake port of described wind-guiding pipeline can be set as required.
Because the position of air intake port of the present utility model can be set as required, can change the collection position of alternating current generator cooling air like this, determine that according to the actual state of alternating current generator on car load best cooling air imports the position, thereby guarantee that alternating current generator has the best type of cooling, the life-span of having improved alternating current generator under actual whole vehicle state.Be the temperature contrast of adopting existing case alternating current generator and each parts of the present invention below, adopt existing case alternating current generator: alternating current generator cooling air temperature 140 degree, stator temperature 240 degree, diode temperature 220 degree, adjuster temperature 157 degree bearing temperatures 170 degree; Adopt case alternating current generator of the present invention: alternating current generator cooling air temperature 114 degree, stator temperature 230 degree, diode temperature 205 degree, adjuster temperature 150 degree bearing temperatures 160 degree.By above contrast, as seen adopt the present invention can improve the heat sinking function of alternating current generator really.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is existing alternating current generator casing structure schematic diagram;
Fig. 2 is an alternating current generator casing structure schematic diagram of the present invention;
Fig. 3 is the alternator construction schematic diagram that adopts alternating current generator case of the present invention.
Embodiment
As shown in Figure 2, it is an alternating current generator casing structure schematic diagram of the present invention.Case comprises on the shroud body 1 and extended wind-guiding pipeline 2 thereon, is air intake port 3 at wind-guiding pipeline one end, is positioned at the port (not shown) of setting out of shroud body 1.On shroud body 1, be provided with the nut bore 5 that is used for fixing in addition.
As shown in Figure 2, it is the alternator construction schematic diagram that adopts alternating current generator case of the present invention.Shroud body 1 is fixed on the alternating current generator 4 by nut, and the air intake port 3 of wind-guiding pipeline 2 is positioned at the radial position of alternating current generator 4 at this moment.Compare with the ventilating opening 11 (shown in Figure 1) over against axial rear portion that is positioned at alternating current generator 4 in the prior art, air intake port 3 of the present invention has been avoided axial rear portion near high temperature parts such as waste pipes.
When real work, the air intake at the axial rear portion of alternating current generator 4 (collection of cooling air just), because shroud body 1 is sealing, this moment, all air intakes must be by air intake port 3 by wind-guiding pipeline 2 intake duct alternating current generators 4 inside, and the position of air intake port 3 is positioned at the proper position of temperature, such as radially shown in Figure 3.
Position about air intake port 3, can be according to the physical location of alternating current generator 4 at car load, the position of suitable temperature under the whole vehicle state is determined in test through temperature analysis, determine the particular location of air intake port 3 again, compare with relatively more fixing position in the prior art like this, more can adapt to actual needs flexibly, improve the heat sinking function of alternating current generator 4 as much as possible.
Claims (2)
1, a kind of alternating current generator case, it is characterized in that, it at least by the sealing shroud body and on described shroud body extended wind-guiding pipeline form, described shroud body is fixed on the alternating current generator, the position of the air intake port of described wind-guiding pipeline can be set as required.
2, alternating current generator case as claimed in claim 1 is characterized in that, the air intake port of described wind-guiding pipeline is positioned at non axial end one side of engine.
