Description

Fan module

The invention relates to a fan module.

The air outlet of the fan of the electronic device (such as a server) is often rotated and installed with a plurality of windshields. When the fan runs, when the wind flows through the gap between the windshields, the wind flow pushes the windshield to open a certain angle, and each windshield The unevenness of the wind due to the wind will produce a difference in the opening angle. This difference increases the resistance to the wind flow, and the heat dissipation efficiency of the fan is low.

In view of the above, it is necessary to provide a fan module that improves heat dissipation efficiency.

A fan module includes a casing, a fan fixed in the casing, and a wind shielding device mounted on one side of the casing, the wind shielding device includes an outer frame fixed to the outer casing and a plurality of blocks pivotally connected to the outer frame And a windshield and a connecting piece connecting the windshield, each windshield comprises a main body piece and a connecting portion disposed on the main body piece, the linking piece comprises a main body rod and a plurality of pivoting portions spaced apart from the main body rod The connecting portion of the windshield rotatably connects the corresponding pivoting portion of the rod linkage.

Compared with the prior art, the windshield of the windshield of the fan module generates the same opening angle under the traction of the linkage, which can reduce the resistance to the wind flow and improve the heat dissipation efficiency of the fan.

Figure 5 is an enlarged view of the portion V in Figure 4.

Figure 6 is a side view of Figure 4.

Referring to FIG. 1 , the fan module 200 of the present invention includes a casing 201 , two fans 202 mounted side by side in the casing 201 , and two windshield devices 100 fixed to one side of the casing 201 .

The outer casing 201 is substantially rectangular parallelepiped, and includes an end wall 2011. The end wall 2011 defines a circular venting opening 2012 corresponding to each fan 202.

The windshield device 100 includes a square outer frame 10, a plurality of windshields 20 mounted on the outer frame 10 from top to bottom, and a linking member 30 connecting the windshields 20.

The outer frame 10 includes two vertical brackets 11, each of which opens a plurality of uniformly spaced fixing holes 111 from top to bottom.

Referring to FIG. 2 together, the linking member 30 includes a substantially strip-shaped main body rod 31. One side of the main body rod 31 protrudes from the top to the bottom with a plurality of evenly spaced pivoting portions 32, and each pivoting portion 32 is away from the main body rod. One end of the 31 defines a pivot hole 33.

Referring to FIG. 3 together, each windshield 20 includes a substantially rectangular body piece 21. A pivot 22 is respectively protruded from one end of the main body 21, and a square notch 23 is defined in a middle portion of the other side of the main body piece 21. A side wall of the notch 23 protrudes from the other side wall with a shaft-shaped connecting portion 231. . A gap 232 is left between the connecting portion 231 and the other side wall of the notch 23.

Referring to FIG. 4 and FIG. 5 together, the pivots 22 of the windshields 20 are respectively inserted into the corresponding fixing holes 111 of the bracket 11 to pivot one side of the windshield 20 to the outer frame 10. The pivoting portions 32 of the linking member 30 are respectively inserted into the gaps 232 of the corresponding windshield 20, and then placed on the corresponding connecting portions 231 to mount the linking member 30 on the other side of each of the windshields 20. The outer frame 10 is fixed to the outer casing 201 for each vent hole 2012. In this embodiment, the outer frame 10 can be fixed to the end wall 2011 of the outer casing 201 by screwing or gluing.

Referring to FIG. 6 together, when the fan 202 is running, the wind flow is blown out from the gap between the two adjacent windshields 20, and the wind flow pushes the windshield 20 and the end wall 2011 at an angle α (the angle α ranges from 0 degrees). ~90 degrees), under the action of the linkage 30, the opening angle α of each windshield 20 and the end surface 2021 can be substantially consistent, the same opening angle α is beneficial to reduce the resistance to the wind flow, and improve the heat dissipation efficiency of the fan. .

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the spirit of the invention are intended to be included within the scope of the following claims.
