Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of motor, more particularly to a kind of motor blower fan.
Background technology
Motor can operationally produce heat, if these heats shed not in time, circuit will be caused to burn so that electricity
Machine failure, even more so that motor is on fire burn, therefore current motor is typically all fixed with positioned at motor rear end by motor shaft
Fan blade at lid, for being motor radiating.
Current motor blower fan has thrust type and centrifugal two kinds, i.e., fan blade has prismatic blade（It is centrifugal）Or provided with blades angle
Blade（Thrust type）, centrifugal prismatic blade fan blade typically do not have much relations with motor axle steer, and it radially throws away air,
Bypass air through radiating groove to radiate motor housing, radiating effect is preferable, but suction is smaller, at back end cover for motor
Radiating effect is bad；The wind of the blowout of the fan blade with angle of thrust type is longitudinal, and wind acts on motor rear end and covers and rebound
Go back, motor housing is radiated, radiating effect is not good, but its suction is big, and air exchanges timely, to back end cover for motor
The thermal diffusivity at place is good, and the wind of longitudinal direction can also be radiated by the longitudinal notch arranged to motor internal.
The content of the invention
The purpose of this utility model is directed to the above-mentioned problems in the prior art, there is provided a kind of good heat dissipation effect
Motor blower fan.
The purpose of this utility model can be realized by following technical proposal：A kind of motor blower fan, including tubular peace
Dress seat, if described mounting seat is circumferentially uniformly fixed with dry plate blade, each blade is obliquely installed and helically paddle, described
Blade has arc-shaped side edges and straight sided, it is characterised in that the blade face welding of described blade is fixed with and is set near arc-shaped side edges
The wind guide strip put, described wind guide strip is vertical and is set parallel to straight sided, and described wind guide strip has in inboard end and is in
The kink that arc-shaped bends to front edge direction.
When this motor blower fan works, helically the blade of paddle can blow out longitudinal wind, and suction is big, and air exchanges
In time, can be to being radiated at motor rear cover, the wind of longitudinal direction also can be by the longitudinal notch arranged at electric machine casing to motor
Inside is radiated, and wind guide strip plays guide effect in addition, and part wind does centrifugal motion along gib block, and the wind for throwing away is by dissipating
Heat channel radiates to motor housing, and the wind rebounded from motor rear cover can also radiate to motor housing.
In a kind of above-mentioned motor blower fan, the blade face welding of described blade is fixed with curved and is set near wind guide strip
The wind-guiding counterlath put, the spacing between described wind-guiding counterlath inner end and kink is more than between wind-guiding counterlath outer end and wind guide strip
Spacing.Wind-guiding counterlath strengthens guide effect, and spacing is different to be caused from the air tool blown out between wind-guiding counterlath and wind guide strip
There is certain compression, wind-force is good.
In a kind of above-mentioned motor blower fan, the ribs of horn shape, institute are welded with the nearly root in blade face of described blade
The ribs stated also is welded with the outer phase of mounting seat.So structural strength is high, long service life.
In a kind of above-mentioned motor blower fan, described mounting seat has axial extension and is cylindrical in shape in the end of blade face side
Extension, described extension is consistent with the aperture of mounting seat.Extension increases the contact area of mounting seat inwall, with electricity
The installation of arbor is more firm.
Compared with prior art, the suction of this motor blower fan is big, and air exchanges timely, and good heat dissipation effect, knot
Structure is firm, long service life.

Specific embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, this motor blower fan includes tubular mounting seat 1, mounting seat 1 is circumferential to be uniformly fixed with five blades
2, each blade 2 is obliquely installed and helically paddle, and Leaf inclination is 28 °, and blade 2 has arc-shaped side edges 2a and straight sided 2b, leaf
The blade face welding of piece 2 is fixed with the wind guide strip 3 set near arc-shaped side edges 2a, and wind guide strip 3 is vertical and is set parallel to straight sided 2b
Put, wind guide strip 3 has the kink 3a bent to straight sided 2b directions in arc-shaped, wind guide strip 3 and bending in inboard end
The arc angle of portion 3a is 120 °.
Further describe in detail, in order to increase guide effect, the blade face welding of blade 2 is fixed with curved and close wind guide strip 3
The wind-guiding counterlath 4 of setting, spacing between the inner end of wind-guiding counterlath 4 and kink 3a more than the outer end of wind-guiding counterlath 4 and wind guide strip 3 it
Between spacing, wind guide strip 3 and wind-guiding counterlath 4 highly consistent and be one centimetre；In order to improve structural strength, blade 2
The ribs 5 of horn shape is welded with the nearly root in blade face, ribs 5 is also welded with the outer phase of mounting seat 1, and mounting seat 1 is in blade face side
End there is axial extension and tubular extension 1a, extension 1a are consistent with the aperture of mounting seat 1.
When this motor blower fan works, helically the blade 2 of paddle can blow out longitudinal wind, and suction is big, and air hands over
Change in time, can be to being radiated at motor rear cover, the wind of longitudinal direction also can be by the longitudinal notch arranged at electric machine casing to electricity
Radiated inside machine, wind guide strip 3, wind-guiding counterlath 4 play guide effect in addition, part wind does centrifugal motion along gib block,
The wind for throwing away is radiated by radiating groove to motor housing, and also motor housing can be dissipated from the wind of motor rear cover bounce-back
Heat, good heat dissipation effect.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
