With the rapid development of the IT industry, the high-speed, high-frequency and integration of electronic components (such as CPUs, hard drives, and graphics cards) in electronic devices such as servers have caused a sudden increase in heat generation. Affect the normal operation of the electronic device. Currently, screws are often used to secure the fan to the server to dissipate the heat generated by the electronic components. This type of installation is not only inconvenient to disassemble the fan, but also produces noise.

In view of the above, it is necessary to provide a fan module that is easy to assemble and disassemble.

A fan module includes a fan, a mounting bracket, a plurality of first fastening components, and a plurality of second fastening components. The mounting bracket includes a base plate. The plurality of fastening holes are formed on the substrate, and the fan includes a side plate, and the side plate is opened. a plurality of fixing holes respectively facing the fixing holes of the substrate, the first fastening component comprising a rod portion, a head portion at one end of the rod portion, and a fastening portion at the other end of the rod portion, the first fastening member is along the axis of the rod portion A through hole extending through the rod portion, the head portion and the fastening portion is formed, the inner surface of the fastening portion forms a wedge block in the through hole, and the second fastening member includes a shaft rod, and the rod portion of the first fastening member passes through The fastening hole of the substrate and the fixing hole of the fan expose the fastening portion of the first fastening component to the inner side of the side plate of the fan, and the shaft of the second fastening component penetrates the through hole of the corresponding first fastening component When the shaft of the second fastening component passes through the through hole at the fastening portion, the wedge-shaped block of the inner surface of the fastening portion is pressed, so that the fastening portion is outwardly deformed and expanded, thereby blocking the side plate of the fan. Inside.

Compared with the prior art, the fan module of the present invention conveniently fixes the fan to the mounting bracket by using the first fastening component and the second fastening component, and only needs to remove the second fastening component from the first fastening component when disassembling. It can be extracted and it is convenient to assemble and disassemble.

Referring to FIG. 1 and FIG. 2 , the fan module of the present invention includes a mounting bracket 20 , a fan 40 , a plurality of vibration dampers 50 , a plurality of first fastening components 60 , and a plurality of second fastening components 70 .

The mounting frame 20 is substantially U-shaped and includes a substrate 22 and two side plates extending perpendicularly from opposite sides of the substrate 22. A venting hole 221 is defined in the center of the substrate 22. The substrate 22 defines a fastening hole 222 at a position adjacent to the four corners. Each of the fastening holes includes a large end 223 on the outer side and a small end 224 on the inner side.

The fan 40 includes a side plate 42 , and a fixing hole 422 is defined in each of the four corners of the side plate 42 .

Each of the vibration damping members 50 is integrally formed of a vibration damping material such as rubber. The damper member 50 has a cylindrical shape, and a through hole 51 is defined in the center thereof in the axial direction. A circumferential groove of each of the damper members 50 defines a card slot 52 in a direction perpendicular to the axial direction.

Referring to FIG. 3 together, each of the first fastening members 60 includes a rod portion 62, a head portion 64 at one end of the rod portion 62, and a fastening portion 68 at the other end of the rod portion. The first fastening member 60 defines a through hole 621 penetrating the rod portion 62, the head portion 64 and the engaging portion 68 in the axial direction of the rod portion 62. The outer circumferential diameter of the engaging portion 68 is the same as the diameter of the rod portion 62. The inner circumferential diameter of the engaging portion 68 gradually transitions from one end of the adjacent rod portion 62 to an end away from the rod portion 62 so that the extension line of the inner and outer circles of the engaging portion 68 is at an acute angle α, and is further within the engaging portion 68. The surface forms a circle of wedge blocks 682 in the through holes 621. A plurality of slots 684 are defined in the axial direction at the ends of the engaging portions 68. The first fastening component 60 is made of an elastic material such as hard plastic or metal.

Each of the second fastening members 70 has a rivet shape and includes a shaft 72 and a head 74 at one end of the shaft 72. The side of the head portion 74 facing the shaft 72 opens an annular receiving portion 742 around the shaft 72 (see Fig. 5). The outer diameter of the shaft 72 is sized to fit tightly with the through hole 621 of the first fastening member 60.

Referring to FIG. 4 and FIG. 5 together, the vibration damper 50 is inserted into the fastening hole 222 of the mounting bracket 20 during assembly, and the vibration damping member 50 is inserted into the fastening hole 222 from the large end 223 of the fastening hole 222. Thereafter, the vibration damper 50 is pushed inward, and the card slot 52 of the vibration damper 50 is engaged with the small end 224 of the fastening hole 222. The side plate 42 of the fan 40 is corresponding to the substrate 22 and is in close contact with the damper 50. The fan blade 40 faces the vent hole 221 in the center of the substrate 22, and the fixing hole 422 of the fan 40 faces the through hole 51 of the damper member 50, respectively. . The first fastening member 60 is inserted from the other side of the substrate 22 away from the fan 40 through the through hole 51 of the corresponding vibration damper 50 and the fixing hole 422 of the fan 40. The engaging portion 68 is exposed to the inner side of the side plate 42 of the fan 40. The shaft 72 of the second fastening component 70 is inserted into the through hole 621 of the corresponding first fastening component 60, and the head 64 of the first fastening component 60 is received in the head 74 of the second fastening component 70. Inside the housing portion 742. When the shaft 72 of the second fastening member 70 passes through the through hole 621 at the fastening portion 68, the wedge block 682 of the inner surface of the fastening portion 68 is pressed to deform the expansion portion 68 outwardly to the buckle. When the inner surface of the joint portion 68 is completely attached to the shaft 72, the angle between the extension line of the outer surface of the engaging portion 68 and the extension line of the inner surface thereof is an acute angle β angle (the angle β is approximately the same as the angle α), and thus the buckle The outer surface of the joint portion 68 forms a stopper portion 686. The stopper portion 686 is blocked from the inner side of the side plate 42 of the fan 40, and the side plate 42 of the fan 40 is locked to the substrate 22, and the vibration damping member 50 is located at the side plate 42 and the substrate 22. The fan 40 is damped between the two. The slot 684 of the latching portion 68 serves to increase the elasticity of the latching portion 68, and the latching portion 68 is more susceptible to deformation when the shaft 72 is passed.

In addition, when disassembling, the shaft 72 of the second fastening component 70 is only pulled out from the through hole 621, and after the fastening portion 68 is restored to the original shape, the rod portion 62 of the first fastening component 60 can be conveniently taken from the fan 40. The fixing hole 422 is removed and the disassembly is convenient.

Obviously, in the case that the shock absorbing effect is not high, the use of the vibration damper 50 can be eliminated, and at the same time, the size of the head portion 64 of the first fastening component 60 can be increased, and the first fastening component 60 and the second buckle can be utilized. The fitting 70 directly fixes the fan 40 to the substrate 22.

The fan module of the present invention fixes the fan 40 to the mounting bracket 20 by using the first fastening component 60 and the second fastening component 70. When disassembling, the second fastening component 70 only needs to be extracted from the first fastening component 60. Preferably, the assembly and disassembly is convenient; the vibration damping member 50 is disposed between the fan 40 and the mounting frame 20 for damping.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
