Description
Technical field
The present invention relates to motor radiating technology, specially a kind of hybrid motor radiating structure.
Background technology
In recent years, constantly develop with electromechanics trade, small size is constantly pursued by motor manufacturing enterprise, high power density,
The material of high electromagnetic load and thermic load is more and more adopted, the loss producing during motor operation increases, leads in design of electrical motor
The overall temperature rise of machine of sending a telegraph is too high or local temperature rise is too high, not only can reduce the service life of motor, the efficiency of impact motor, torque
Etc. economic and technical norms, also can cause electric machine structure part gross distortion, jeopardize motor operation safety.
When conventional motors adopt air water cooling structure, support water channel adopts spiral channel or S type water channel, and cooling water leans on external water
Pump carries out pressurized circulation, and in water channel, water resistance is larger, and the hydraulic pressure of needs is higher, therefore the sealing system of motor is required higher, and
There is the risk that cooling water enters motor internal；Motor internal air-cooled employing centrifugal fan or aerofoil fan, less efficient.
In prior art, as shown in Figure 6, Figure 7, its construction features is as follows for the technical scheme of electric machine stand water-cooled S type water channel：
A. electric machine stand water-cooled S type water channel is welded on inner core by gusset, and outside weldings outer tube is formed；
B. cooling water becomes S type to flow through in water channel, and cooling water channel is longer, and cooling effect of motor is preferable；
C. at the 180 degree dogleg passage of S type water channel two ends, water resistance is larger, there is the backflow of " vortex " shape of a small range；
D. water channel is welded by gusset, and manufacture method is ripe, process is simple, and cost is relatively low.
In prior art, technical scheme such as Fig. 8, Fig. 9 of electric machine stand water spiral channel show, its construction features is as follows：
A. motor helical water channel is converted into after cylinder by monoblock steel plate and processes, outside weldings outer tube；
B. the water resistance of spiral channel is less, and flow velocity is fast, and velocity is uniformly, has optimal circulating effect；
C. spiral water groove processing is difficult, relatively costly.
Existing electric machine stand water-cooling spiral water channel or the shortcoming of S type water channel technical scheme：
A. support water channel adopts spiral channel or S type water channel, and cooling water outer portion water pump carries out pressurized circulation, and hydraulic pressure is larger, water
Infiltration phenomenon in road often occurs；
At the 180 degree dogleg passage of b.S type water channel two ends, water resistance is larger, there is the backflow of " vortex " shape of a small range；
C. spiral water groove processing is difficult, relatively costly；
D. need after support welding processing to carry out the water pressure test, costly and the cycle is long.
Content of the invention
The present invention be solve current water-cooling spiral water channel or S type water channel exist water channel infiltration phenomenon or water resistance larger and plus
The difficult technical problem of work, provides a kind of hybrid motor radiating structure.
The present invention employs the following technical solutions realization：A kind of hybrid motor radiating structure, including electric machine stand, front
End cap, rear end cap, the main frame stator being located at electric machine stand internal cavities and main rotor；Wound motor support outer wall is machined with many
Individual parallel water channel, electric machine stand fixed sleeves are provided with water jacket, pass through O-ring seal between the two ends of water jacket and electric machine stand outer wall
Realize sealing；Gap is left between water jacket inwall and the cell wall end edge of parallel water channel（Guarantee the cooling liquid energy entering through water inlet
Enough flow to each parallel water channel）；Water jacket top is provided with the water inlet for irrigating coolant being connected with many parallel water channels, water
Set bottom is provided with the outlet being connected with many parallel water channels.
Further, the internal cavity near drive end bearing bracket of electric machine stand is provided with the mixed flow fan being contained on machine shaft.
Further, the motor rotor punching sheet constituting main rotor is machined with axial ventilation road.
New-type electric machine mixed cooling structure of the present invention is shell water-cooled（Water+ethylene glycol）, plus rotor is cold from fan.Motor
Support is formed using steel plate welding processing, and support is machined with parallel water channel, and equipped with water jacket, water jacket and support are by O-shaped for outside
Sealing ring is sealed.Coolant（Water+ethylene glycol）Sprayed on support by water jacket top water inlet pipe, gone out by water jacket bottom
The mouth of a river is flowed out automatically, need not provide extra pressure.Carry out heat exchange, motor rotor punching sheet equipped with mixed flow fan with the external world in rotating shaft
On be machined with axial ventilation road, reduce temperature of rotor.
After the present invention program is implemented, can effectively reduce motor temperature rise, farthest meet motor and pursue small size, Gao Gong
The requirement of rate density.Support adopts parallel water channel, processes simple, and can be prevented effectively from support and seeps water because water channel hydraulic pressure is larger
Generation.Motor, using having larger air quantity after mixed flow fan, can have greater pressure again, can at utmost play wind
The effect of fan.
