Wherein: 1, armature spindle, 2, internal fan, 21, blade one, 22, transverse plane, 23, hole, location seat, 24, connect wheel hub, 3, external fan, 31, air guide ring, 32, blade two, 33, positioning sleeve, 4, rotor, 5, stator, 6, end cap.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figure 1 to Figure 3, a kind of Radiution vane for motor structure, including rotor axis of electric 1, it is arranged on the rotor 4 on described armature spindle 1, and the stator 5 that is arranged on motor and end cap 6.It is internally located on described armature spindle 1 at described end cap 6 and is provided with internal fan 2, be positioned at outside described end cap 6 on described armature spindle 1 and be provided with external fan 3.Use inside and outside fan combination that motor is lowered the temperature, substantially increase the radiating efficiency of motor.
It addition, internal fan 2 includes blade 1, transverse plane 22, hole, location seat 23 and connects wheel hub 24.Blade 1 is to have the rectangular block of certain arcuation and be uniformly arranged on transverse plane 22, and one end is fixed with transverse plane 22, is configured to one side semi-closed structure.Transverse plane 22 is connected the fixing connection of wheel hub 24 in flat circular and inner circle with described.The internal body cavity allowing armature spindle 1 to pass that has of hole, location seat 23, connection is fixed with being connected wheel hub 24 in outside.Space between transverse plane 22 with hole, location seat 24 is separated into air inlet by being connected wheel hub 23, and the space between adjacent blades 1 is air outlet.Blade 1 is surrounded with rotor 4 end face and closes into an one-way conduction runner by transverse plane 22 jointly, air-flow can only pressurize through internal fan 2 from air inlet, discharging through air outlet, the high pressure draught preventing blade 1 from producing leaks from the side end face of blade 1, improves the radiating efficiency of internal fan 2 further again.
The blade 21 of internal fan 2 can use poly-indentation to fall into cambered design, can produce a high pressure draught district at recess, when high pressure power effect by centrifugation, throw away through air outlet, and the air-flow of air inlet is continuously replenished higher-pressure region, thus forms a centrifugal high pressure air channel.There are unique air inlet and unique air outlet in whole air channel, so the centrifugal high pressure draught produced that runs will not overflow from blade 1 end face, owing to blade 1 uses poly-pressure leaf, therefore centrifugal flow pressure can be significantly increased, and radiating effect is significantly increased, under the same terms, compared with classic flat-plate leaf, enamel-covered wire maximum temperature rise can decline 1/3, and line bag temperature rise resistance reduces, and electric efficiency promotes.
It addition, external fan 3 includes air guide ring 31, blade 2 32 and positioning sleeve 33.Blade 2 32 is curved shape in twisted shape, and quantity is 3-6 sheet, compared with existing heat-dissipating impeller, it is possible to provide the air quantity that effectively dispels the heat of several times even decades of times, and the temperature rise of motor can be made to decline to a great extent, and the temperature rise of line bag declines, and the resistance of line bag is the least, and the efficiency of motor is the highest.Adding a circle air guide ring 31 in the periphery of external fan 3 blade 2 32, air guide ring 31 is in circular, and height coordinates with the angle of inclination of blade 2 32.Air guide ring 31 not only makes the distinguished and admirable concentration of external fan 3; improve radiating efficiency; and air guide ring 31 can protect external fan 3 blade 2 32; the clashing and breaking that blade occurs it are not easy during transport and assembling; furthermore; because of air guide ring 31, limit the aging deformation of blade 2 32, the heat radiation quality of flabellum is effectively ensured.
Being connected to a positioning sleeve 33 in the middle of blade 2 32, positioning sleeve 33, in circular, have in annulus and coordinates fixing fastening part with armature spindle 1, and fastening part can be holding screw.Meanwhile, 5 fixing it is connected stepped for blade design with positioning sleeve, thus allows blade outlet air surface closer to motor surface.Blade 2 32 outer annular diameter is suitable with motor housing mesopore external diameter, owing to the distinguished and admirable pressure of external fan 3 is axial, so that internal stator line bag can easily be dispelled the heat by the distinguished and admirable of flabellum through motor housing, reduce line bag temperature rise, reduce resistance temperature rise, improve electric efficiency.Stepped arrangement being connected outside described positioning sleeve 33 inside blade 2 32, stepped arrangement being connected inside described air guide ring 31 outside blade 2 32.This structure makes blade 2 32 connect into an entirety with positioning sleeve 33 and air guide ring 31, and structure is more firm, it is simple to heat radiation.
This utility model has good heat dissipation effect, motor working efficiency advantages of higher.
