Description
Technical field
The utility model is related to a kind of dc motor, specifically a kind of double wind cooling DC motor.
Background technology
Dc motor is the electric rotating machine for direct current energy to be converted to mechanical energy, and critical component therein is brush
And armature, armature are formed by connecting by many coils by rule, coil generally use high strength enamelled wire or glass fiber packet flat type copper wire
It is coiled into.When dc motor works, brush and coil multiple-contact generate heat so that the temperature in dc motor shell
Degree gradually rises, and is easy on fire.
Existing dc motor generally cools down to shell using air-cooled, and specifically dc motor wherein is outer
Wind turbine is arranged in side one end, air outlet is arranged in the side of the other end, at air outlet position, windage gradually increases, and wind-force is gradual
Weaken, air cooling effect is poor.
Utility model content
The purpose of this utility model is just to provide a kind of double wind cooling DC motor, to solve existing dc motor windage
Greatly, the problem of air cooling effect difference.
The utility model is realized in this way：
A kind of double wind cooling DC motor are provided at the top of one end of dc motor shell and divulge information to housing cavity
First wind turbine is provided with air outlet on the side wall of the other end close to dc motor shell, in the straight of setting air outlet one end
Auxiliary air cooling mechanism is additionally provided on stream motor field frame, the auxiliary air cooling mechanism includes fan housing and is arranged on the fan housing
The second wind turbine；The fan housing is located on the air inlet that dc motor case top is outputed, on the side wall of the fan housing
It is provided with unhurried current air port；The power of second wind turbine is less than the power of the first wind turbine.
The unhurried current air port is opened on the opposite side wall in two positions of the second fan housing, plane where the unhurried current air port and
Dc motor shell axis direction is perpendicular.
The utility model in air outlet one end of dc motor shell by the basis of existing dc motor, setting
Auxiliary air cooling mechanism, and the setting unhurried current air port on the fan housing of auxiliary air cooling mechanism are set, using the first wind turbine and the second wind turbine institute
The wind of blowout carries out wind cooling temperature lowering to shell jointly, enhances air-cooled effect, improves air-cooled efficiency, prevent because of direct current drive
Casing temperature is excessively high and damages equipment.
The utility model is simple in structure, of low cost, easy to operate, substantially extends the service life of dc motor, fits
In popularization and application.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1, dc motor shell, the 2, first wind turbine, 3, air outlet, the 4, second wind turbine, 5, fan housing.
Specific implementation mode
As shown in Figure 1, the utility model is to be provided with the first wind turbine 2 at the top of the rear end of dc motor shell 1, connecing
It is provided with air outlet 3 on the side wall of the front end of nearly dc motor shell 1, is also set up in the front top of dc motor shell 1
There is auxiliary air cooling mechanism.Auxiliary air cooling mechanism includes fan housing 5 and the second wind turbine 4, and the second wind turbine 4 is arranged on fan housing 5, the second wind
The power of machine 4 is less than the power of the first wind turbine 2；The bottom of fan housing 5 is connected with dc motor shell 1.At the top of fan housing 5
It is provided with air inlet, fan housing 5 is located on air inlet, and unhurried current air port is offered on the side wall of fan housing 5, and unhurried current air port opens up
On the opposite side wall in two positions of fan housing, and the plane where air port that flows slowly mutually is hung down with dc motor shell axis direction
Directly, i.e., shown in Fig. 1 in uncovered structure fan housing 5 front-end and back-end be unhurried current air port.
Using such structure, after the wind that the first wind turbine 2 is blown out enters dc motor shell 1, along direct current drive
Casing body 1 flows to the air outlet 3 of the other end；On the one hand, since the power of the second wind turbine 4 is less than the first wind turbine 2, unit interval
Interior air output is less, on the other hand, due to being provided with unhurried current air port on the side wall of fan housing 5, the wind that the second wind turbine 4 is blown out
Unhurried current air port of the part through fan housing 5 sheds so that the wind for entering dc motor shell 1 is more soft, prevents from being significantly increased
The windage of first wind turbine, 2 blown out wind；Remaining another part wind is with the wind from the first wind turbine 2 jointly to being located at direct current
The coil progress of 1 front end of motivation shell is air-cooled, then goes out from air outlet 3.
Claims (2)
1. a kind of double wind cooling DC motor are provided with to divulge information to housing cavity at the top of one end of dc motor shell
One wind turbine is provided with air outlet on the side wall of the other end close to dc motor shell, which is characterized in that in setting air outlet
Auxiliary air cooling mechanism is additionally provided on the dc motor shell of one end, the auxiliary air cooling mechanism includes fan housing and is arranged in institute
State the second wind turbine on fan housing；The fan housing is located on the air inlet that dc motor case top is outputed, in the fan housing
