Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fan blades, in particular to a pressurized fan blade. Background Art
[0002] At present, in the fan blade assembly used in the cooling fan, the fan blade assembly is mainly composed of hardware and plastic parts, and the plastic part is the fan blade part; in the prior art, the fan blades are arranged at equal intervals, however, such a fan blade arrangement does not achieve a good noise reduction effect and a pressurization effect, resulting in a smaller air output in the cooling fan of the same specification, which in turn affects the cooling efficiency of the cooling fan and also reduces the use quality of the cooling fan; for this reason, we propose a pressurized fan blade. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a supercharged fan blade. After the improvement, the fan blade assembly can achieve better noise reduction and supercharging effects, increase the output of air volume, and thus improve the heat dissipation efficiency and use quality of the cooling fan.
[0004] The technical solution of the utility model is:
[0005] A supercharged fan blade comprises a fan blade assembly, wherein the fan blade assembly is composed of hardware and a fan blade body;
[0006] The fan blade body is provided with a first fan blade and a second fan blade, and the second fan blade is symmetrically arranged; the spacing between adjacent first fan blades is greater than the spacing between adjacent second fan blades; the thickness of the first fan blade and the second fan blade are both 0.25 mm.
[0007] Furthermore, the first fan blade and the second fan blade are each provided with a plurality of blades.
[0008] Furthermore, the hardware and the fan blade body are injection molded structures.
[0009] Furthermore, the fan blade body is made of plastic.
[0010] Furthermore, the second fan blades are symmetrically arranged left-right or top-bottom.
[0011] Furthermore, the spacing between adjacent first blades is 2.1 mm.
[0012] Furthermore, the spacing between adjacent second blades is 1.7 mm.
[0013] The beneficial effects of the utility model are:
[0014] Compared with the prior art, the utility model sets the fan blade body as the first fan blade and the second fan blade, and the spacing between the second fan blades is smaller than the spacing between the first fan blades, so as to increase the number of fan blades, thereby increasing the air outlet and wind pressure, so that the air output of the cooling fan is increased, and the second fan blades are symmetrically arranged, so that the fan blade assembly is more balanced when rotating, which can reduce noise; in addition, the thickness of the first fan blade and the second fan blade is reduced, which can increase the space of the air outlet between adjacent first fan blades and between adjacent second fan blades, and can also increase the wind pressure and increase the output of air volume. In summary, the boosted fan blades of the utility model can improve the heat dissipation efficiency and use quality of the cooling fan. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a structural schematic diagram of the utility model.
[0016] In the figure, 1. hardware; 2. fan blade body; 3. first fan blade; 4. second fan blade. DETAILED DESCRIPTION
[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:
[0018] like Figure 1 As shown,
[0019] A booster fan blade includes a fan blade assembly, which is composed of hardware 1 and a fan blade body 2; the hardware 1 and the fan blade body 2 are injection molded structures; the fan blade body 2 is provided with a plurality of first fan blades 3 and a plurality of second fan blades 4, and the plurality of first fan blades 3 and the plurality of second fan blades 4 can be divided into two parts, such as: the first fan blades 3 are respectively the first part and the second part; the second fan blades 4 are respectively the third part and the fourth part; the second fan blades 4 of the third part and the fourth part are symmetrically arranged, so that the first fan blades 3 of the first part and the second part are also symmetrically arranged, so that the fan blade assembly is more balanced when rotating, and the noise can be reduced on the basis of this structure.
[0020] As a preferred embodiment; the spacing between adjacent first fan blades 3 is 2.1mm, and the spacing between adjacent second fan blades 4 is 1.7mm; the purpose of this design is to make the spacing between adjacent first fan blades 3 greater than the spacing between adjacent second fan blades 4, in order to increase the number of fan blades; in this embodiment, the number of fan blades is 39, while the number of fan blades set on the existing equivalent fan blade assembly is 35 (each fan blade is set at equal intervals), so under this structure, the number of fan blades can be increased, and then the air outlet and wind pressure can be increased, so that the air output of the cooling fan is increased, and the heat dissipation efficiency and use quality of the cooling fan are improved.
[0021] As a preferred embodiment; the thickness of the first fan blade 3 and the second fan blade 4 are both 0.25mm; the fan blade thickness in the prior art is 0.4mm, so the fan blade is changed from the original 0.4mm to the current 0.25mm, thereby increasing the space of the air outlet between adjacent first fan blades 3 and between adjacent second fan blades 4, which can also increase the wind pressure and increase the output of air volume.
[0022] As a preferred embodiment, the second fan blades 4 are symmetrically arranged left-right or up-down; that is, the second fan blades 4 of the third part and the fourth part can be symmetrically arranged left-right or up-down, and can be symmetrical no matter how the direction of the fan blade assembly is swung.
[0023] It should be pointed out that the main problem in the prior art is that: in the prior art, the fan blades are arranged at equal intervals, however, such fan blade arrangement does not achieve a good noise reduction effect and a supercharging effect, resulting in a small air volume among cooling fans of the same specifications, thereby affecting the cooling efficiency of the cooling fan;
[0024] Therefore, through the improvement of the present application, a first fan blade 3 and a second fan blade 4 are provided, and the spacing between the second fan blades 4 is smaller than the spacing between the first fan blades 3, in order to increase the number of fan blades; moreover, the second fan blades 4 are symmetrically arranged, so that the fan blade assembly is more balanced when rotating, which can reduce noise; in addition, the thickness of the first fan blades 3 and the second fan blades 4 is also reduced, which can increase the space of the air outlet between adjacent first fan blades 3 and between adjacent second fan blades 4, and also can increase the wind pressure and increase the output of air volume; the heat dissipation efficiency and use quality of the cooling fan are improved in the overall structure.
[0025] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
