Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figures 1 to 5, a kind of motor radiating structure including rotor axis of electric 1, is arranged on the armature spindle 1
Rotor 4 and the stator 5 being arranged on motor and end cap 6.It is internally located in the end cap 6 on the armature spindle 1 and is equipped with interior wind
Fan 2 is located on the armature spindle 1 outside the end cap 6 and is equipped with external fan 3.Motor is dropped using inside and outside fan combination
Temperature substantially increases the radiating efficiency of motor.
In addition, internal fan 2 includes blade 1, transverse plane 22, positioning hole seat 23 and connection wheel hub 24.Blade 1 is tool
There is the rectangular block of certain arcuation and be uniformly arranged on transverse plane 22, one end is fixed with transverse plane 22, and it is semiclosed to be configured to single side
Structure.Transverse plane 22 is fixedly connected in flat annular shape and inner circle with the connection wheel hub 24.It is provided with inside positioning hole seat 23
The body cavity that armature spindle 1 is allowed to pass through, outside is fixedly connected with being connected wheel hub 24.Space between transverse plane 22 and positioning hole seat 23
Air inlet is separated by connection wheel hub 24, the space between adjacent blades 1 is air outlet.Transverse plane 22 is total to 4 end face of rotor
Closing is surrounded into an one-way conduction runner with by blade 1, air-flow can only pressurize from air inlet through internal fan 2, then through air outlet
Discharge prevents the high pressure draught that blade 1 generates from being leaked from the side end face of blade 1, further improves the heat dissipation of internal fan 2
Efficiency.
The blade 21 of internal fan 2 can be used poly- indentation and fall into cambered design, can generate a high pressure draught area in recess, work as height
Pressure is acted on through centrifugal force, is thrown away through air outlet, the air-flow of air inlet is continuously replenished to higher-pressure region, so as to form a centrifugal high pressure wind
Road.There are unique air inlet and unique air outlet in entire air passage, so the high pressure draught that centrifugation operation generates will not be from blade 1
End face is overflowed, and since blade 1 uses poly- pressure leaf, centrifugal flow pressure can be significantly increased, and heat dissipation effect significantly increases
Add, under the same terms, compared with classic flat-plate leaf, enameled wire maximum temperature rise can decline 1/3, and line Bao Wensheng resistance is reduced, motor
Improved efficiency.
In addition, external fan 3 includes air guide ring 31, blade 2 32 and positioning sleeve 33.Blade 2 32 is curved in oblique lateral bending, quantity
For 3-6 pieces, compared with existing heat-dissipating impeller, it is possible to provide effective heat dissipation air quantity of several times or even dozens of times can make the Wen Sheng of motor
It declines to a great extent, the temperature of line bag, which rises, to be declined, and for the resistance value of line bag with regard to small, the efficiency of motor is just high.In the periphery of 3 blade 2 32 of external fan
A circle air guide ring 31 is added, air guide ring 31 highly coordinates in annular shape with the angle of inclination of blade 2 32.Air guide ring 31 is not only
Make 3 distinguished and admirable concentration of external fan, improve radiating efficiency, and air guide ring 31 can protect 3 blade 2 32 of external fan, transporting and assembling
It is not easy the clashing and breaking for blade occur in the process, furthermore, because of air guide ring 31, the aging deformation of blade 2 32 is limited, is had
Effect ensures the heat dissipation quality of flabellum.
A positioning sleeve 33 is connected among blade 2 32, positioning sleeve 33 is in annular shape, is had in annulus with the cooperation of armature spindle 1 admittedly
Fixed fastening part, fastening part can be holding screws.Meanwhile be fixedly connected with positioning sleeve 5 by blade design is stepped, so as to
Blade outlet air surface is allowed closer to motor surface.2 32 outer annular diameter of blade is suitable with motor housing mesoporous outer diameter, due to external fan 3
Distinguished and admirable pressure be axial so that the distinguished and admirable of flabellum can easily radiate to internal stator line bag through motor housing,
Line Bao Wensheng is reduced, reduces resistance Wen Sheng, improves electric efficiency.The stepped arrangement in the inside of blade 2 32 and with the positioning
33 outside connection of set, the stepped arrangement in 2 32 outside of blade are simultaneously connected with 31 inside of air guide ring.The construction makes blade two
32 connect into an entirety with positioning sleeve 33 and air guide ring 31, and structure is more secured, convenient for heat dissipation.
Auxiliary radiating device 7 is additionally provided in addition, being located at outside the end cap 6 on the armature spindle 1.The auxiliary heat dissipation
Device 7 includes radiator fan 73, and the shape of radiator fan 73 is identical with the shape of external fan 3, but volume is more than outer radiator fan
3, heat dissipation effect is more preferable than external fan 3.73 outside of radiator fan is equipped with wind scooper 71, is provided on the wind scooper 71 by radiation air
The wind that fan 73 generates all guides the air guide hole of motor into.Wind scooper is respectively provided with hook 72 in both sides about 71, and hook 72 can be used to hang
Ice bag is put, is cold wind when the wind that radiator fan 73 generates being made to reach motor, the radiating efficiency of motor is greatly improved.It is described auxiliary
Help radiator 7 detachable, when motor works in a short time, it is only necessary to which internal fan 2 and external fan 3 dissipate well with regard to that can reach
Thermal effect when motor works long hours, in a short time can be lowered the temperature of motor by auxiliary radiating device 7, tool
There is good heat dissipation effect, so as to improve the work efficiency of motor.
The present invention has many advantages, such as that good heat dissipation effect, motor working efficiency are high.
