Description
Technical Field
The utility model relates to a fan field, concretely relates to high-effect radiator fan.
Background
The notebook computer can generate heat during normal operation, and in order to accelerate the heat dissipation of the notebook computer, a notebook computer manufacturer installs a heat dissipation fan inside the notebook computer and exhausts the heat inside the notebook computer in an air cooling mode.
However, the fan wheel of the heat dissipation fan is driven by the motor, the motor also generates heat during operation, if the number of the fan wheels is too large, the air outlet area of the heat dissipation fan is reduced, if the thickness of the fan blades on the fan wheel is too thin, the rigidity of the fan blades is low, the resistance applied to the rotation of the fan wheel is large, the rotation of the motor not only generates more heat energy, but also correspondingly increases the loss of the generated mechanical energy when the rotating fan wheel rotates.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model provides a radiator fan, the technical problem that solve is that present inside radiator fan's of notebook flabellum thickness and flabellum total number do not match, and the resistance when the flabellum rotates is big, and the motor rotates the utilization ratio of the mechanical energy that produces low.
For solving the technical problem, the utility model provides a following technical scheme: the utility model provides a cooling fan, includes fan frame, fan wheel and motor, and the fan frame includes base and apron, and the base is connected with the apron, is equipped with the air intake on the base, is equipped with the air outlet on the apron, and fan wheel and motor are all installed inside the fan frame, and the rotation axis of motor drives the fan wheel and rotates, and the structure of every flabellum on the fan wheel is the same, and the ratio of single flabellum thickness on the fan wheel and flabellum total amount is between 0.08% and 0.65%.
Further, the thickness of the fan blades is between 0.1mm and 0.3 mm.
Further, the total number of fan blades is between 47 and 106.
Compared with the prior art, the utility model beneficial effect who has is: the ratio of the thickness of a single fan blade of the fan wheel to the total number of the fan blades is between 0.08% and 0.65%, when the heat dissipation fan works, the resistance of the rotation of the fan wheel is small, the utilization rate of mechanical energy generated by the rotation of the motor is high, the air output is increased, the vibration is reduced, and the noise is reduced.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-3, a heat dissipation fan includes a fan frame, a fan wheel and a motor, the fan frame includes a base 1 and a cover plate 2, the base 1 is connected with the cover plate 2, an air inlet 3 is disposed on the base 1, an air outlet 4 is disposed on the cover plate 2, the fan wheel and the motor are both mounted inside the fan frame, a rotating shaft of the motor drives the fan wheel to rotate, each fan blade 5 on the fan wheel has the same structure, and the ratio of the thickness of a single fan blade 5 on the fan wheel to the total number of the fan blades 5 is between 0.08% and 0.65%.
The thickness of the fan blades 5 is between 0.1mm and 0.3 mm.
The total number of fan blades 5 on the fan wheel is between 47 and 106.
The thickness of a single blade 5 in fig. 3 is 0.3mm, the number of blades 5 on the impeller is 47, and all blades 5 are evenly distributed on the impeller.
The thickness of a single fan blade 5 in fig. 4 is 0.1mm, the number of fan blades 5 on the fan wheel is 106, and all fan blades 5 are evenly distributed on the fan wheel.
To sum up, the utility model discloses a ratio of single flabellum 5 thickness and 5 total numbers of flabellum of impeller is between 0.08% and 0.65%, and this radiator fan is little at the resistance that the impeller rotation of during operation received, and the motor rotates the utilization ratio of the mechanical energy that produces high, and then increases the air output, reduces the vibration, the noise reduction.
In light of the above, the present invention is not limited to the above embodiments, and various changes and modifications can be made by the worker without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
