Abstract
The utility model discloses a motor fan, include the fan hub and set up at the positive a plurality of fan blades of fan hub, the fan blade includes the second end that is close to the central first end of fan hub and keeps away from the fan hub center, each the second of fan blade is served and is provided with first inclined plane, first inclined plane towards the fan hub openly, be the acute angle between first inclined plane and the horizontal plane. The utility model discloses a motor fan, second serve and are provided with first inclined plane, and first inclined plane towards the fan hub openly for the fan is effectual has controlled amount of wind dispersion loss amount, sees through the motor casing fin with what the amount of wind was more concentrated, thereby realizes that the temperature rise reduces effect promotion further, and simple structure.
Description
Technical field
The utility model is related to motor technology field, more particularly, to a kind of electrical motor fan.
Background technology
Motor produces certain heat in operation process, is provided with fan to radiate in motor.The fan end of prior art
Portion is circular arc or pyramidal structure in shaft section, and air quantity is less, and the heat that such as motor produces is more, then cannot meet motor
Radiating needs.
Utility model content
Technical problem to be solved in the utility model is: a kind of structure of offer is simple, the more preferable motor of radiating effect
Fan.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: provides a kind of electrical motor fan, bag
Include fan hub and some fan blades being arranged on fan hub front, described fan blade include near fan hub center first end and away from
Second end at fan hub center, the second end of each described fan blade is provided with the first inclined plane, described first inclined plane direction
Fan hub front, at an acute angle between described first inclined plane and horizontal plane.
Further, described second end be shaped as arrow shaped.
Further, the material of described fan hub and fan blade is respectively plastics.
Further, the described fan hub back side is provided with reinforcement.
Further, the quantity of described fan blade is 5.
The beneficial effects of the utility model are: electrical motor fan of the present utility model, the second end is provided with first and inclines
Inclined-plane, and the first inclined plane towards fan hub front so that fan be effectively controlled air quantity dispersion number of dropouts, air quantity is more collected
In transmission motor casing fin, thus realize temperature rise reducing effect further being lifted, and structure is simple.
Brief description
Fig. 1 is the front view of the electrical motor fan of the utility model embodiment；
Fig. 2 is the sectional view of Fig. 1；
Fig. 3 is the rear view of the electrical motor fan of the utility model embodiment.
Label declaration:
1st, fan hub；2nd, fan blade；21st, first end；22nd, the second end；3rd, reinforcement；4th, the first inclined plane.
Specific embodiment
By describing technology contents of the present utility model in detail, being realized purpose and effect, below in conjunction with embodiment and join
Close accompanying drawing to be explained in detail.
The design of the utility model most critical is: this fan is provided with the first inclined plane on the second end 22, described
Towards fan hub 1 front, at an acute angle between described first inclined plane and horizontal plane, this fan is effectively controlled one inclined plane 4
Air quantity disperses number of dropouts, effectively increases radiating effect.
Refer to Fig. 1 to Fig. 3, the utility model electrical motor fan, including fan hub 1 and be arranged on fan hub 1 front
Some fan blades 2, described fan blade 2 includes near the first end 21 at fan hub 1 center and the second end 22 away from fan hub 1 center,
First inclined plane is provided with the second end 22 of each described fan blade 2, described first inclined plane 4 is towards fan hub 1 front, described
At an acute angle between first inclined plane and horizontal plane.
Knowable to foregoing description, the beneficial effects of the utility model are: electrical motor fan of the present utility model, the second end
It is provided with the first inclined plane on 22, and the first inclined plane 4 is towards fan hub 1 front so that fan is effectively controlled air quantity divides
Diffusing vector, by the transmission motor casing fin of air quantity more concentration, thus realize temperature rise reducing effect further being lifted, and
And structure is simple.
Further, described second end 22 be shaped as arrow shaped.
Further, the material of described fan hub 1 and fan blade 2 is respectively plastics, certainly, in some other embodiment
It can be metal or alloy.
Further, described fan hub 1 back side is provided with reinforcement 3.
Further, the quantity of described fan blade 2 is 5, certainly, is alternatively 3,4 or 6 in some other embodiment
More than individual.
Refer to Fig. 1 to Fig. 3, embodiment one of the present utility model is: the present embodiment electrical motor fan, including fan hub 1
And it is arranged on 5 fan blades 2 in fan hub 1 front, fan hub 1 back side is provided with reinforcement 3, and the material of fan hub 1 and fan blade 2 is divided
Not Wei plastics, this fan be used for motor internal is cooled down.
This second end 22 be shaped as arrow shaped.This fan blade 2 is included near the first end 21 at fan hub 1 center and away from wind
Second end 22 at fan hub 1 center, the second end 22 of each fan blade 2 is provided with the first inclined plane, the first inclined plane 4 is towards fan
Hub 1 front, at an acute angle between the first inclined plane and horizontal plane.
In sum, the electrical motor fan that the utility model provides, structure is simple, can the dispersion of effective control air quantity run off
Amount, the transmission motor casing fin of air quantity more concentration effectively more improves radiating effect.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalents made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in the technology neck of correlation
Domain, is all included in the same manner in scope of patent protection of the present utility model.
