Abstract
The utility model discloses a fan blade for a cooling fan of an automotive alternating current power generator. The fan blade comprises a base body (1), wherein a plurality of blade bodies are arranged on the base body (1), and points of intersection of the blade bodies and a fan blade pitch cercle (2) serve as reference points of the blade bodies. The blade bodies are arranged on the base body (1) in order in an anti-clockwise direction, angles corresponding to arc lengths between two adjacent reference points of all the reference points distributed in the anti-clockwise direction serve as central angles of the blade bodies, and a central angle of each blade body is different from the central angles of the blade bodies adjacent to the blade body. The fan blade for a cooling fan of the automotive alternating current power generator is simple in structure, and noise can be reduced remarkably.
Description
Technical field
The utility model relates to a kind of flabellum of radiating fan of automobile AC generator.
Background technique
Existing rotor fan leaf blade is designed to circumferencial direction even angle between even number sheet and sheet and sheet more and distributes, more than alternator is generally all operated in the rotating speed of 3000rpm/min on motor, the fan noise being produced by obstructed blade so easily produces resonance, and mechanical noise measured value is larger.
Summary of the invention
For the defect of prior art, the utility model provides a kind of flabellum of radiating fan of automobile AC generator.
A kind of flabellum of radiating fan of automobile AC generator, comprise matrix 1, on matrix 1, be provided with multiple blades, the intersection point of each blade and flabellum pitch circle 2 is the reference point of this blade, blade is arranged by counter clockwise direction order on matrix 1, by facing mutually the central angle that two angles corresponding to the arc length between reference point are blade in each reference point of counterclockwise arranging, the central angle of two blades that the central angle of each blade is adjacent is different, each blade all has the first tapered plane 12 and the second tapered plane 13 that are connected with matrix 1, between the first tapered plane 12 and the second tapered plane 13, be acute angle.
Optionally, described blade is 9, and the central angle of each blade is by being counterclockwise followed successively by: 30 degree, 51 degree, 34 degree, 27 degree, 58 degree, 35 degree, 46 degree, 41 degree, 38 degree.
The beneficial effects of the utility model are: simple in structure, can significantly reduce noise.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model flabellum.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other object of the present utility model, Characteristics and advantages.In whole accompanying drawings, identical reference character is indicated identical part.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present utility model.
Consult Fig. 1, for the flabellum of radiating fan of automobile AC generator, comprise matrix 1, on matrix 1, be provided with 9 blades, the reference point that the intersection point of each blade and flabellum pitch circle 2 is this blade, 9 blades by anticlockwise arrangement mode are on matrix 1: the first blade 3, the second blade 4, the three blades 5 ... the 9th blade 10, the ten blades 11; Taking the reference point on the first blade 3 as starting point, be its central angle by facing mutually two angles corresponding to the arc length between reference point in each reference point of counterclockwise arranging, two central angles that each central angle is adjacent are different, and for example central angle can be followed successively by: 30 degree, 51 degree, 34 degree, 27 degree, 58 degree, 35 degree, 46 degree, 41 degree, 38 degree.Each blade all has between the first tapered plane 12 of being connected with matrix 1 and the second tapered plane 13, the first tapered planes 12 and the second tapered plane 13 and is acute angle.
Flabellum for radiating fan of automobile AC generator of the present utility model, compared with flabellum of the prior art, by the arrangement mode of blade is changed, is adjusted corresponding central angle simultaneously, reaches the object of improving noise tonequality.
In above description, a lot of details are set forth so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be implemented to be much different from alternate manner described here, and therefore the utility model is not subject to the restriction of disclosed concrete enforcement above.Any skilled personnel are not departing from technical solutions of the utility model scope situation simultaneously, all can utilize method and the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Every content that does not depart from technical solutions of the utility model,, all still belongs in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present utility model.
Claims (2)
