Abstract
The utility model relates to a cooling fan for generator, including adj. Tabular main part and blade, both integrated into one piece, it has a plurality of wind holes excessively that are the circumference equipartition to open in the adj. Tabular main part, the blade set up the front of adj. Tabular main part and with cross wind hole one -to -one, the cross section of blade is the arch, and the air inlet direction arch height of following cooling fan reduces until the edge with crossing the wind hole even as an organic wholely gradually to formation has into the arc in wind gap cover structure, and the wind hole of crossing that the arc cover will correspond covers totally, and when cooling fan rotates, wind is from going into in the wind gap gets into the blade, along the arc cover turn over after certain angle again by the discharge of wind hole. Increase air inlet pressure and intake, improve heat exchange efficiency, promote to send out motor heat dissipation, avoid the generator internal part overheated to improve the output of generator.
Description
Technical field
The utility model relates to a kind of cooling fan, is specifically related to a kind of cooling fan for generator.
Background technique
Generator is in work runs, electric current produces heat in staor winding and rotor windings, the pivot friction of rotor also can produce heat, on the other hand, due to the change in magnetic field, in iron core, loss is produced, iron core temperature is raised, generator generation heat is more thus, when temperature is higher, can affect the cooperation between each parts and operation.
At present, generator used in everyday is all equipped with cooling fan, its fan is mainly used to disturbance generator gas flow, the Stator and Rotor Windings hot air of position unshakable in one's determination and the cooler air of winding two ends end position are exchanged, promote that heat exchange is carried out in generator and outside, the heat in generator is discharged outside generator, and cool air is drawn in generator again and cools, thus ensure generator-temperature detection stable and uniform, keep good working order.
Model utility content
It is higher that this model utility aims to provide a kind of cooling effectiveness, can effectively avoid generator temperature too high, thus improve the cooling fan of generated output power.
For this reason, the technological scheme that the utility model adopts is: a kind of cooling fan for generator, and comprise plate-like body and blade, both are one-body molded, it is characterized in that: described plate-like body has some circumferentially uniform mistake air holes; Described blade be arranged on plate-like body front and with cross air holes one_to_one corresponding, the cross section of described blade is arch, air intake direction dome height along cooling fan reduces until be connected as a single entity with the edge crossing air holes gradually, thus the arc-shaped cover structure formed with wind inlet, and the mistake air holes of correspondence covers by arc-shaped cover completely, when cooling fan rotates, wind enters in blade from wind inlet, and arcuately cover is discharged by crossing air holes after turning over certain angle again.
Further, the medial extremity opposed outer ends of described blade arched cross-section, air intake direction tilts backwards; The top opposing root of described wind inlet, air intake direction tilts backwards; Whole blade is had and stronger digs wind effect, provide more wind-force to cool, the cooling effectiveness of amplification generator.
Further, the center of described plate-like body has rotating shaft through hole; At rotating shaft through hole and excessively between air holes, centered by rotating shaft through hole, be symmetrically arranged with mounting hole; The rotating shaft bore periphery at the described plate-like body back side is provided with blind hole; And be also provided with two locating columns at the plate-like body back side, described locating column is symmetrical arranged centered by rotating shaft through hole; The back side of plate-like body is attachment face, and the design of blind hole better can dodge mounting parts, possesses good stability when locating column then can ensure that cooling fan operates.
On the basis of such scheme, the material of described cooling fan is that PA66 increases glass, and compared with traditional nylon material, PA66 increases glass can make whole fan have better rigidity and stability, increases the service life.
The beneficial effects of the utility model are: fan blade uses the design of arc-shaped cover, can farthest carry out digging wind, add aspiration pressure and air output, also improve heat exchange efficiency, promote generator heat-radiation, ensure generator temperature stabilization, thus improve the output power of generator.

Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
As shown in figures 1-4, a kind of cooling fan for generator, form primarily of plate-like body 1 and blade 2, both are one-body molded, plate-like body 1 has 6 circumferentially uniform mistake air holes 3, blade 2 be arranged on plate-like body 1 front and with cross air holes 3 one_to_one corresponding, in addition, the cross section of blade 1 is arch, air intake direction dome height along cooling fan reduces until be connected as a single entity with the edge crossing air holes 3 gradually, thus the arc-shaped cover structure formed with wind inlet 4, and the mistake air holes 3 of correspondence covers by arc-shaped cover completely, the medial extremity opposed outer ends of blade 2 arched cross-section, air intake direction tilts backwards, the top opposing root of wind inlet 4, air intake direction tilts backwards, when cooling fan rotates, wind enters in blade 2 from wind inlet 4, discharge by crossing air holes 3 again after arcuately cover turns over certain angle, and then enter generator and carry out exchange heat.
Rotating shaft through hole 6 is had in the center of plate-like body 1; At rotating shaft through hole 6 and excessively between air holes 3, centered by rotating shaft through hole 6, be symmetrically arranged with mounting hole 5; Rotating shaft through hole 6 periphery at described plate-like body 1 back side is provided with blind hole 8; And be also provided with two locating columns 7 at plate-like body 1 back side, locating column 7 is symmetrical arranged centered by rotating shaft through hole 6.
In the present embodiment, the material of cooling fan is that PA66 increases glass.
