Description

Stable fan blade

Technical Field

The utility model relates to a flabellum structure field especially relates to a firm type flabellum.

Background

Along with the development of the electronic industry in recent years, the performance of electronic components is continuously improved, the operation speed is faster and faster, the operation speed of internal chip groups is continuously improved, the number of chips is continuously increased, the heat emitted by the chips during working is correspondingly increased, if the heat is not emitted in time, the performance of the electronic components is greatly influenced, the operation speed of the electronic components is reduced, the electronic components can be burnt along with the continuous accumulation of the heat, and therefore the heat of the electronic components must be dissipated.

When the fan blades are machined, the distance between the blades of the conventional fan blades is not easy to control, and the fan blades are unbalanced under the condition that one side is large and the other side is small. Meanwhile, the conventional fan blade is formed by plastic, and has thick blades, few blades and low air volume.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a firm type flabellum has solved the unbalanced problem of flabellum.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a firm type flabellum, including axle center, plastic main part, iron-clad, plastic ring and blade, the plastic main part sets up in the periphery in axle center, the iron-clad sets up the periphery of plastic main part, the blade has a plurality of, the blade is along the lateral surface of iron-clad is equidistant outwards to extend, every the blade is including setting up the first part on the iron-clad and the second part of connection in the first part distal end, first part with the second part all is the arc and crooked opposite direction; the inner ring of the plastic ring is provided with clamping grooves corresponding to the number and the positions of the blades along the circumferential direction of the inner ring, the plastic ring is arranged on the periphery of the second part, and the clamping grooves are clamped on the second part of the blades; the thickness of the blade is gradually reduced from the outer edge of the iron shell to the extending end, and the blade is made of metal.

Further, the thickness of the blade is 0.1-0.3 mm.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:

the stable fan blade of the utility model overcomes the problem of fan blade balance because the plastic ring is arranged at the periphery of the second part of the blade to fix the position of each blade;

furthermore, the metal fan blades are fixed by the plastic main body, so that the number of the blades is large, the noise is low, the rigidity is large, and the blade is ultrathin.
