The cooing pipe is mainly composed of two mutually-communicated parts, namely, a part near the outer surface of the commutator and a part adhered to the outer surface of the stator. A water inlet and a water outlet of the cooling pipe are respectively disposed at the two sides of a motor shell. By adopting the device, the size of a fan is reduced, the air volume is reduced, the defect of motor air-cooling is overcome, a series motor can be cooled effectively, and a high-power series motor is made possible.
Description
Technical field
The present invention relates to motor cooling technology field, especially a kind of series excited machine cooling structure.
Background technology
At present motor cooling is mainly air-cooled structure, i.e. rotor front end equipped with fan, and fan rotation produces air-flow, institute
The air-flow of generation is entered in motor by the air inlet in casing, the distinguished and admirable air gap between stator and rotor, then slave
The air outlet of shell lower end flows out, and heat is taken away, so as to carry out air cooling to rotor.The shortcoming of this structure is：
First, invisible waste is larger.
Second, the distinguished and admirable heat for taking away rotor surface can only be passed through, cooling effect is poor.
3rd, motor noise is larger, and fan is bigger, distinguished and admirable bigger, and cooling effect is better, but the noise that fan is produced
Bigger, the distinguished and admirable vibration produced when motor internal is also bigger.
Another kind of type of cooling of motor is water-cooled, i.e., cooling tube is arranged inside motor casing, and cooling tube is coiled in motor
The internal circular surfaces of external circular surfaces or motor casing overcoat, form spiral type cooling-water duct, water inlet and outlet difference position
In the two ends of motor, cooling water is entered from water inlet, and along spiral channel whole casing is flowed through, then from the outlet of the motor other end
Flow out, take away heat, be embodied as the purpose of electric motor temperature reduction.But cooling water in whole spiral channel by needing certain when
Between, therefore cooling-down effect is not ideal.And this simple spiral aquaporin is not suitable for series excited machine, because series excitation is electric
There are diverter and brush in the top of machine, due to the presence of brush, cooling water pipe cannot outside steering gear coiled coil, so as to nothing
Method is diverter cooling, and then affects the cooling effect of whole motor.Just because of the effective type of cooling of shortage, existing string
Sharp power of motor is generally little.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of cooling structure of series excited machine, using can subtract after the device
Small fan, reduces air quantity, and the defect air-cooled so as to overcome motor, while effectively cooling down series excited machine, makes to do high-power series excitation
Motor is possibly realized.
To solve above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of series excited machine cooling structure, including the rotor of motor, stator, diverter and cooling tube, the cooling tube master
Will by near diverter outer surface and docile in stator outer surface, two parts for interconnecting constitute, the water inlet of cooling tube
Mouth and outlet are respectively positioned at the both sides of motor casing.
Further improvement of the present invention is：Cooling tube on stator and the cooling tube on diverter are respectively provided with
It is the back-shaped structure along the roundabout arrangement in axial direction of stator and diverter.
Further improvement of the present invention is：Back-shaped cooling tube is two pieces, is relatively arranged on and is mutually hung down with the line of two brushes
On straight stator and the side of diverter.
Further improvement of the present invention is：The cooling tube is set to helical structure in stator outer surface, in diverter
Two sides perpendicular with the line of two brushes arrange two back-shaped structures.
Further improvement of the present invention is circle between the cooling tube and the cooling tube on stator being located on diverter
Slip over and cross connection.
Further improvement of the present invention is：Fan is installed in the end of rotor.
As a result of above-mentioned technical proposal, the technological progress that the present invention is obtained is：
The present invention is that series excited machine is lowered the temperature with air cooling way in combination with, effectively, makes to make high-power series excited machine and is possibly realized.
When operating because of series excited machine, pyrotoxin is the part such as line bag, diverter and brush, the present invention in stator outer surface and
Diverter outer surface is provided with cooling tube simultaneously, can directly take away heat by water circulation, while by being constantly passed through cooling
Water sets up cold conditions environment, and heat can be more effectively taken away by the distinguished and admirable of rotation formation of rotor front end fan, has so as to reach
The purpose of effect cooling series excited machine.
The cooling tube of the laundry in the present invention is close to stator surface, and the cooling tube at diverter is near commutator face
But be not in contact with it, so not only the heat at diverter 4 can have been taken away by cooling water but also avoid in diverter rotation process with it is cold
But pipe friction heat.
Rounding off connection between the cooling tube on diverter and the cooling tube on stator is located in the present invention, is made cold
But water flows more smooth in cooling tube, and cooling effect is more preferable.
The position that cooling tube in the present invention at diverter is arranged avoids cooling tube and interferes brush, in cooling motor
Motor normal work is not affected simultaneously.
The present invention is to increase water-cooling structure on the basis of air-cooled, therefore can suitably reduce fan, reduces air quantity, so as to
Overcome the shortcoming that former air-cooled invisible waste is big, vibration is big, noise is big.

Specific embodiment
The present invention is described in further details below in conjunction with the accompanying drawings：
Series excited machine cooling structure, including the rotor 2 of motor, stator 3, diverter 4 and cooling tube 1, the cooling tube 1 is led
Will by near diverter 4 outer surface and docile in the outer surface of stator 3, two parts for interconnecting constitute, i.e., cooling tube 1 exists
Position of stator is that the outer surface for being close to stator is arranged, and cooling tube 1 is in the outer surface that the position of diverter 4 is near diverter 4
But be not in contact with it, not only the heat at diverter 4 can have been taken away by cooling water but also avoid in diverter rotation process with cooling tube
Frictional heat.When operating because of series excited machine, pyrotoxin is the part such as line bag 11 and the brush 5 of diverter 4, therefore is arranged at this position
Cooling tube can realize：First, heat is directly taken away by water circulation；2nd, cold conditions environment is set up, by the wind of the front end of rotor 2
