Technical field
The utility model relates to Heat-dissipating impeller of motor field, particularly relates to a kind of heat-dissipating impeller structure running motor for washer for orientation.
Background technology
The Heat-dissipating impeller of motor generally used at present is flat aluminum leaf, when the rotor rotates, what flat aluminum blade root produced according to centrifugal force distinguished and admirablely cools stator line bag, thus reduces the temperature rise of line bag, reduce the increase of line bag temperature rise resistance, play effect of lifting motor efficiency.But the air quantity that the dull and stereotyped impeller of cast aluminium can provide is little, and blast is little, and due to end face open, air-flow has just from end face spilling after pressure, really can be considerably less to the dispel the heat air-flow that plays a role of line bag, radiating effect is bad, cannot effectively lifting motor efficiency or reduce motor cost.The one that patent discloses being CN200820085638.X as the patent No. has netted pod apertures Heat-dissipating impeller of motor, and this structure increases the area of blade, improves radiating effect to a certain extent.But this impeller does not inherently improve, still adopt flat aluminum leaf, the air quantity of generation is little, and blast is little, and therefore radiating effect is bad.The patent No. be CN203257736U patent discloses a kind of New-type electric machine heat-dissipating impeller, comprise wheel hub and some blades be evenly arranged on excircle, this blade wheel structure is simple, with low cost, but the blade adopted is dull and stereotyped leaf, the air quantity that can produce and blast little, and impeller end face is open, air pressure easily overflows from end face, and the radiating effect played motor is not good.
Utility model content
The utility model is for prior art Problems existing, and provide a kind of good heat dissipation effect, motor working efficiency is high, the heat-dissipating impeller structure running motor for washer for orientation that cost is low.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat-dissipating impeller structure running motor for washer for orientation, comprises armature spindle and is arranged on the rotor pack on described armature spindle; Also comprise poly-pressure impeller; Described poly-pressure impeller comprises blade, transverse plane, location hole seat and is connected wheel hub; Described poly-pressure impeller symmetry is arranged on rotor pack both sides described in motor internal and is positioned on described armature spindle; The direction blade being positioned at the poly-pressure impeller of described rotor pack both sides is contrary; Described poly-pressure impeller closes into an one-way conduction runner by described transverse plane and rotor end-face.
In order to prevent the loss of high pressure draught, centrifugal for flat board leaf is changed into poly-pressure turbine leaf by the utility model, significantly improves the radiating efficiency of impeller; The high pressure draught that the structure adopting transverse plane to be combined with rotor pack end face can prevent turbine leaf from producing leaks from the side end face of turbine leaf, improves the radiating efficiency of impeller further.
Further, described blade is the rectangular block with certain arcuation.
Further, described blade is evenly arranged on described transverse plane, and one end and described transverse plane are fixed.
Further, described transverse plane is that flat circular and inner circle is fixedly connected with the described wheel hub that is connected.
Further, described location hole seat inside has the body cavity allowing described armature spindle to pass, and outside is fixedly connected with the described wheel hub that is connected.
Further, described location hole seat has the fastening part be connected and fixed with described armature spindle.
Further, the space between described transverse plane with described location hole seat is separated into air inlet by being connected wheel hub.
Further, the space between described adjacent blades is air outlet.
Further, described poly-pressure impeller has blade side towards described rotor pack.
Centrifugal for flat board leaf is changed into poly-pressure turbine leaf by the utility model, and by heat-dissipating impeller closed at both ends, improves the radiating efficiency of impeller, thus improves the operating efficiency of motor.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation running the heat-dissipating impeller structure of motor for washer for orientation of the utility model;
Fig. 2 is the structural representation of heat-dissipating impeller in Fig. 1.
Wherein: 1, armature spindle, 2, rotor pack, 3, heat-dissipating impeller, 4, air inlet, 6, transverse plane, 7, blade, 8, location hole seat, 9, wheel hub is connected.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of heat-dissipating impeller structure running motor for washer for orientation, the rotor pack 2 comprising armature spindle 1 and be arranged on described armature spindle 1, rotor pack 2 both sides are symmetrically installed with poly-pressure impeller 3 respectively, and poly-pressure impeller 3 is arranged on armature spindle 1; Blade 7 direction being positioned at the poly-pressure impeller 3 of described rotor pack 2 both sides is contrary; Described poly-pressure impeller 3 closes into an one-way conduction runner by described transverse plane 6 and rotor end-face.Poly-pressure impeller 3 comprises blade 7, transverse plane 6, location hole seat 8 and is connected wheel hub 9.Location hole seat 8 has the body cavity for being arranged on armature spindle 1, outside location hole seat 8 be connected wheel hub 9 and be fixedly connected with; Connect wheel hub 9 to be fixedly connected with inside circular transverse plane 6; Blade 7 is poly-pressure turbine leaf, and be evenly arranged on transverse plane 6, blade 7 one end and transverse plane 6 are fixed.Centrifugal for flat board leaf is changed into poly-pressure turbine leaf, significantly improve the radiating efficiency of impeller.
In addition, poly-pressure impeller 3 outerplanar uses injection moulding annular to surround, and the impeller that acyclic end face surrounds and rotor pack 2 end face develop, and when rotating like this, the air-flow of recess can only be discharged by centrifugal force, and can not run off to the both ends of the surface of impeller.Blade 7 is configured as one side semi-closed structure, there is air inlet, air outlet, transverse plane 6 etc., impeller end plane 6 is outside rotor pack 2 end face, and impeller closes into an one-way conduction runner by transverse plane 6 and rotor pack 2 end face, air-flow can only pressurize from air inlet through impeller, discharge through air outlet, the high pressure draught preventing turbine leaf from producing leaks from the side end face of turbine leaf again, improves the radiating efficiency of impeller further.
In addition, impeller have employed poly-indentation and falls into cambered design, and can produce a high pressure draught district at recess, when high pressure is through centrifugal action, throw away through air outlet, the air-flow of air inlet constantly adds to higher-pressure region, thus forms a centrifugal high pressure air channel.There are unique air inlet and unique air outlet in whole air channel, run so centrifugal the high pressure draught produced to overflow from vane end faces, because this turbo blade uses poly-pressure leaf, therefore centrifugal flow pressure can significantly increase, and radiating effect significantly increases, under the same terms, compared with classic flat-plate leaf, enamelled wire maximum temperature rise can decline 1/3, and line bag temperature rise resistance reduces, and electric efficiency promotes.When enamelled wire temperature rise is identical, rotor lamination can reduce, and line bag reduces, and cost declines to a great extent.
In addition, in order to meet the requirement of motor direction operation, contrary two of the identical direction blade of overall dimension poly-pressure impeller 3 symmetry is used to be arranged on rotor pack 2 two ends, when motor runs, the heat-dissipating impeller 3 of both sides all exports identical High Voltage flow heat dissipation air-flow, the heat on rapid band cabling bag surface, serves radiating effect, thus improves the operating efficiency of motor.
The utility model has good heat dissipation effect, and motor working efficiency is high, low cost and other advantages.
