Abstract

The utility model relates to a vehicular air-cooled generator. A plurality of air inlets are arranged on the end surface of a rear end cover, and a plurality of air outlets are arranged on the side circumferential surface of the rear end cover. A plurality of air outlets are evenly distributed on the end surface of a front end cover, an inner fan is arranged on rotor axis which is arranged between the inner side of the rear end cover and a rotor, and meanwhile, an outer fan is arranged on the rotor axis which is extended outside the front end cover. The side circumferential surface of the front end cover corresponding to the front end part of a stator is provided with a plurality of air inlets. The utility model overcomes the existing disadvantages of the existing single-fan outer installing and double-fan inner installing air-cooled generator that the temperature of the front end part of the stator is higher or the temperature of the iron core which is arranged on the middle part of the stator is higher. The front end part, the rear end part and the middle part of the stator, a rectification bridge, etc. can be evenly cooled. The lower temperature can be retained, and the manufacturing technique is simpler.

Description

A kind of automobile-used air-cooled generator
Technical field
The utility model belongs to technical field of generators, is specifically related to a kind of air-cooled mechanism of alternator for vehicle.
Background technology
Generator on the automobile generally all adopts the force air cooling, its a kind of air-cooled structure is on the rotor center axle outside stretching out front end of shield fan to be installed, under this fan effect, cold air enters from generator bonnet air intake window, through rectifier bridge heat radiating fin, stator rearward end coil, rotor gap, stator leading section coil, discharged by fan at front end housing air-out window at last.From above-mentioned air channel cooling path as can be known, the cooling effect of generator unit stator leading section is the poorest, and temperature drift often causes the anterior ageing of insulation of stator to puncture easily.Another kind of air-cooled mechanism is separately installed with internal fan between generator front and rear cover and rotor, one of its cooling air channel path is that cold air sucks from front end housing air-inlet window mouth, after the heat exchange of stator leading section coil, discharges from front end housing air outlet window mouth; Two of cooling air channel path is that cold air sucks from rear end cap air intake window, through rectifier bridge heat radiating fin and stator rearward end coil, discharge from rear end cap air-out window, this shows that this structure air cooling system is preferable to end heat radiation before and after the stator, and it is relatively poor to the cooling at stator middle part, and two fans are installed in generator inside, and are also comparatively complicated on manufacturing process.
Summary of the invention
It is reasonable that the purpose of this utility model provides a kind of air-cooled structure, even to the cooling of generator unit stator front and back end coil, middle part iron core and rectifier bridge, efficient is high, and the comparatively simple automobile-used air-cooled generator of manufacturing process.
Art designs scheme of the present utility model is: it comprises stator, rotor, rectifier bridge and front and rear cover, thereafter the end face of end cap is provided with and offers some air outlets on some air inlets, the lateral circle surface, be evenly equipped with some air outlets on the end face of front end housing, on the rotor center axle between rear end cap inboard and the rotor, internal fan is installed, simultaneously external fan is installed stretching out on the front end housing outside rotor central shaft, the front end with respect to stator on the lateral circle surface of front end housing offers some air inlets.
The utility model air channel flow scheme design is reasonable, it has overcome adorns the too high or higher shortcoming of stator middle part iron core temperature of stator leading section temperature that air-cooled generator exists in outer dress of existing single fan and the double fan, make coolings such as generator unit stator end, front and back and middle part, rectifier bridge evenly, keep lower temperature, and manufacturing process is comparatively simple, provides a kind of good air-cooled generator in particular for the large and medium bus of the very high generator postposition of ambient temperature.
Description of drawings
Accompanying drawing is a general structure schematic diagram of the present utility model.
Embodiment
This air-cooled generator is by stator 7, rotor 6, rectifier bridge 11 and front end housing 3, rear end cap 13 constitutes, the two ends of the central shaft 1 of rotor 6 are supported on the bearing 16 that is installed in the front and rear cover middle part respectively, on 15, one end of rotor center axle 1 also stretches out outside the front end housing 3, be close to front end housing 3 lateral surfaces external fan 2 and belt pulley 17 are installed on rotor center axle 1 successively, on the rotor center axle 1 between rear end cap 13 inboards and the rotor 6, internal fan 10 is installed simultaneously, on the end face of rear end cap 13, offer some air inlets 12 near periphery, in order to strengthen cooling to rear bearing 15, also offer some bearing air inlets 14 at rear end cap 13 middle parts, rear end cap 13 lateral circle surface ends offer some air outlets 9, and being evenly equipped with some air outlets 4 on the end face of front end housing 3, the front end with respect to stator 7 on the lateral circle surface of front end housing 3 offers some air inlets 8.When generator operation, be installed in the external fan 2 on the rotor center axle 1, internal fan 10 rotates thereupon, so cold air sucks from rear end cap air inlet 12, through rectifier bridge 11, after the heat absorption of stator rearward end coil, a part is forced to discharge from air outlet 9 by internal fan 10, portion of air continues the middle part by stator 7, after the anterior heat exchange, through front end housing air outlet 4, external fan fan blade outlet 5 is discharged, also have one fresh cold air to enter simultaneously from front end housing air inlet 8, strengthened cooling, then also through front end housing air outlet 4 to stator 7 leading section coils, external fan fan blade outlet 5 is discharged.
