Embodiment 1

[0033] figure 1 It is a schematic diagram of the first component structure of the fan blade structure in the embodiment of the present invention, such as figure 1 As shown, the fan blade structure may include: a wheel housing assembly 101, a first fan blade set 102 and a second fan blade set 103; wherein,

[0034] The first blade set 102 and the second blade set 103 are asymmetrically distributed on different sides of the wheel housing assembly 101 .

[0035] Usually, the noise of the heat sink is mainly caused by the cutting of the air flow by each fan when it rotates, and the periodic cutting of the air flow by each fan will cause the air flow to vibrate periodically, so each fan will Sound waves are generated periodically, and the sound waves generated by each fan are superimposed on each other to form the noise that people hear.

[0036] In the existing heat dissipation device, since the first fan blade group and the second fan blade group are symmetrically distributed o...

Embodiment 2

[0040] The fan blade structure provided in this embodiment may include: a wheel housing assembly 101, a first fan blade set 102 and a second fan blade set 103; wherein,

[0041] The first fan blade set 102 is arranged on the first side of the wheel housing assembly 101;

[0042] The second fan blade set 103 is arranged on the second side of the wheel housing assembly 101;

[0043] the second side is the opposite side of the first side;

[0044] The first blade set 102 and the second blade set 103 are asymmetrically distributed on different sides of the wheel housing assembly 101 .

[0045] The fan blade structure described in the embodiment of the present invention is further limited on the fan blade structure described in the first structural embodiment. This embodiment provides a first fan blade group and a second fan blade group arranged on the wheel housing assembly The fan blade structure on different sides has the advantages of simple implementation and low manufacturi...

Embodiment 3

[0047] The fan blade structure provided in this embodiment may include: a wheel housing assembly 101, a first fan blade set 102 and a second fan blade set 103; wherein,

[0048] The first blade set 102 and the second blade set 103 are asymmetrically distributed on different sides of the wheel housing assembly 101 .

[0049] Wherein, the shapes of the blades included in the first blade set 102 and the second blade set 103 are different.

[0050] The fan blade structure described in the embodiment of the present invention is further limited on the fan blade structure described in the first structural embodiment. The fan blade structure has the advantages of simple realization and low manufacturing cost.

Abstract

The invention discloses a fan blade structure, a cooling device and electronic equipment. The fan blade structure comprises a wheel shell assembly, a first fan blade set and a second fan blade set. The first fan blade set and the second fan blade set are asymmetrically distributed on the different sides of the wheel shell assembly.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a fan blade structure, a heat dissipation device and electronic equipment. Background technique [0002] A heat dissipation device is usually arranged on the surface of the electronic component, and the heat dissipation device generally includes: a wheel housing assembly, a first fan blade group and a second fan blade group, wherein the first fan blade group is arranged on the first side of the wheel housing assembly, and the second fan blade group is arranged on the first side of the wheel housing assembly. The two fan blade sets are arranged on the second side of the wheel shell assembly, and the first fan blade set and the second fan blade set are symmetrically distributed on different sides of the wheel shell assembly. During use, it is found that such a cooling device has a problem of high noise due to heat dissipation. Contents of the invention [0003] In view ...
