Description
[technical field]
The present invention refers in particular to a kind of cooling fan structure of cylinder flabellum about fan art.
[background technique]
The flabellum of general fan has after rotation makes air-flow by the air-flow angle Jing Guo design, makes air-flow above and below aerofoil
Surface flow causes the difference in speed because of surface distance length difference.Because very fast in upper limb airflow on surface flowing velocity,
Therefore it is corresponding around gas pressure it is smaller, and it is slower in bottom wing airflow on surface flowing velocity, thus it is corresponding around gas pressure compared with
Greatly, the pressure difference of this different size, so that the pressure that the pressure of lower aerofoil pushes top airfoil to thus generates lift.The lift is anti-
Active force forms airflow thrust, and air-flow generates the effect of work done by aerofoil turning, and then shows fan duty.
The rib structure outline border however, traditional sound impeller structure or single moving vane are arranged in pairs or groups, because of flabellum wing-shaped structure reciprocal effect
Under, cause Kuanping Terrane on noise and narrow frequency noise generally larger.Furthermore conventional fan structure, because the wing influence of flabellum makes
Air-flow is flowed out in diffusion mode, therefore its antipyretic degree is insufficient for the heater element in system internal fan dead astern.
Therefore how will solve the problems, such as it is above-mentioned with missing, as the inventor of this case to be engaged in the related of the industry
Manufacturer wants the direction place person of research improvement.

To between line c22, c23；Angle β between rotating cylindrical body 30c and rotating cylindrical body 30a be defined in axial line c21, c23 it
Between.
In another implementation, the rotating cylindrical of the radial surface 2112 of the radial wheel hub 210 that the rotary body 20 is arranged in
Body 30a, 30b, 30c are asymmetric geometry setting, as shown in Figure 8 B.Wherein asymmetric geometry setting is exactly rotating cylindrical body two-by-two
The angle α of 30a, 30b, 30c, the angle of β, γ be not identical.In conclusion the invention has the advantages that；
1. can be provided when the rotary body 20 of radiator fan 10 rotates by the first conductive part 24 and the second conductive part 25
Power supply gives the second stator pack 32 of each rotating cylindrical body 30 being located on the outer surface of rotary body 20 to drive the rotating cylindrical
Self rotation of body 30, must avoid supply lines from interfering.
2. the axial surface 2111 that wheel hub 210 is arranged in the rotating cylindrical body 30 can generate radial radiation flowing, setting exists
The radial side 2112 of wheel hub 210 can generate axial flowing.
3. via the air-flow of 30 export of rotating cylindrical body, because without under known wing flabellum variation reciprocation,
So relatively small in its identical antipyretic lower noise level.
4. it is more restrained via the air-flow of 30 export of rotating cylindrical body and range is wider, therefore for the fever member in system
The part conductance that can directly be bullied guides to heat source or direct circulation takes away heat source.
The above has been described in detail, only as described above, only preferable embodiment,
When the range that cannot limit implementation of the invention.I.e. all equivalent changes and modifications etc. made according to the present patent application range, all should be still
Belong to the patent covering scope of the present invention.
