In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is the present invention
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to according to
These accompanying drawings obtain other accompanying drawing.
Fig. 1 is the structural representation of the radiator fan that the embodiment of the present invention provides.
Detailed description of the invention
Embodiments provide a kind of radiator fan, reduce the waterproof and dustproof difficulty of rotor self, thus drop
Low cost.
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
Refer to accompanying drawing 1, the radiator fan that the embodiment of the present invention provides includes support 1, stator and rotor, and stator is fixed on
On support 1, rotor is rotatably arranged on support 1, and stator and rotor are along the pivot center directional spreding of rotor.
The stator of the present invention does not has overlapping of axial location in the direction of the axis of rotation with rotor, it is simple to separately fabricated rotor
Waterproof and dustproof structure, so reducing the waterproof and dustproof difficulty of rotor self, thus reduce cost.
Preferably, support 1 is provided with the first installation cavity 11 and the second installation cavity 12 along pivot center directional spreding, fixed
Son is arranged in the first installation cavity 11, and rotor is arranged in the second installation cavity 12.The present invention offers two installations on support 1
Chamber, it is simple to stator and the assembling of rotor and installation, easily facilitates simultaneously and rotor is carried out waterproof and dustproof.Certainly, the present invention also may be used
Only to arrange the installation cavity arranged along pivot center direction on support 1, rotor and stator are arranged at this installation cavity
In, then utilize the sealing structure of following process, rotor and stator are kept apart.
Further in technical scheme, separated by division board 4 between the first installation cavity 11 and the second installation cavity 12.This
Bright make rotor and seal stator separate by division board 4, make second installation cavity 12 at rotor place form closed area, closing
The fluids such as air, water, liquid metal can be carried, it is simple to rotor is carried out in region.So, the present invention removes division board
4 waterproof and dustproof structures forming rotor, simple in construction, cost is relatively low.
In order to ensure the normal rotation of rotor, it can be able to be plastics through the material in magnetic field that above-mentioned division board 4 uses
