Description

Impeller for fan

Technical Field

The utility model relates to an impeller for a fan, and belongs to the field of heat dissipation of electronic products.

Background

With the improvement of the performance of the related components of the computer, the heat energy generated during the operation of the computer is relatively improved, wherein the heat energy generated by the central processing unit and the data storage device is the highest, if the generated high heat cannot be dissipated in time, the normal operation performance of the computer will be affected by light persons, and the computer will be burnt and damaged by heavy persons, so that a heat dissipating device must be installed to ensure that the components and the devices normally work at a proper temperature, in particular, the performance of the notebook computer is gradually improved, the requirement on the performance of the heat dissipating fan is higher.

Disclosure of Invention

The utility model aims to provide an impeller for a fan, which is beneficial to improving the height and the number of blades and thinning the blades so as to improve the air output and the silencing effect, and also can increase the overall strength, effectively avoid the deformation of the blades so as to improve the reliability and the service life of a product.

In order to achieve the purpose, the utility model adopts the technical scheme that: an impeller for a fan, comprising: the wheel hub, the first blade of a plurality of and a plurality of second blade, an annular disc are connected and are located the periphery of wheel hub with the lateral surface of wheel hub, the first blade of a plurality of sets up on annular disc one is surperficial, a plurality of second blade sets up on annular disc and the surperficial that the first blade was carried on the back mutually with annular disc.

The further improved scheme in the technical scheme is as follows:

1. in the above scheme, the height of the first blade is greater than the height of the second blade.

2. In the above scheme, the height of the first blade is equal to the height of the second blade.

3. In the above scheme, the number of the first blades exceeds 30.

4. In the above scheme, the number of the second blades exceeds 30.

5. In the scheme, the thicknesses of the first blade and the second blade are both 0.08-0.2 mm.

6. In the above scheme, the height of the first blade exceeds 2 mm.

7. In the above scheme, the height of the second blade exceeds 2 mm.

Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages and effects:

the impeller for the fan is provided with the annular disc, the annular disc is connected with the outer side surface of the hub and is positioned on the periphery of the hub, the plurality of first blades are arranged on one surface of the annular disc, and the plurality of second blades are arranged on the surface of the annular disc opposite to the first blades, so that the impeller is beneficial to improving the height and the number of the blades and thinning the blades, the air outlet quantity and the silencing effect are improved, the overall strength is increased, the deformation of the blades is effectively avoided, and the reliability and the service life of a product are improved.
