Technical Field

[0001] This utility model relates to the field of computer power supplies, and in particular to a computer power supply fan fixing device. Background Technology

[0002] Currently, computer power supply fans are usually fixed to the side wall of the power supply with screws. This not only exposes the screws, affecting the aesthetics of the power supply, but also causes the screws to loosen over time due to the vibration generated by the moving fan, resulting in the fan becoming off-center and noisier.

[0003] Chinese patent document CN221551185U discloses a heat dissipation structure for a computer power supply, which includes a power supply body and fastening bolts. A fan body is housed inside the power supply body, and shock-absorbing mechanisms are provided at the corners of the fan body. Each shock-absorbing mechanism includes a mounting groove with a limiting hole and a mounting hole at its inner bottom. A support pad is provided inside the mounting groove, and the support pad has bolt holes and countersunk holes. A fastening sleeve is located directly below the bolt holes. A protective frame is provided on the top of the power supply body, and mounting rings are provided at the corners of the protective frame. Shock-absorbing rings are located inside the mounting rings. This heat dissipation structure uses four fastening bolts to mount the fan body and bear the weight of the fan. This structure is prone to screw loosening and affects the aesthetics of the computer power supply. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a computer power supply fan fixing device that can support the weight of the fan and has a neat appearance without screws.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a computer power supply fan fixing device, including a first bracket and a second bracket. The first bracket is used to support the bottom of one end of the power supply fan, and the second bracket is used to support the bottom of the other end of the power supply fan. The first bracket is fixed to the first side plate of the outer frame of the computer power supply, and the second bracket is fixed to the second side plate of the outer frame of the computer power supply. Both the first bracket and the second bracket are located inside the outer frame.

[0007] A further technical solution of this utility model is that the first bracket includes a first support plate and a first connecting plate, the upper end of the first connecting plate is connected to the first side plate, and the first support plate is fixed to the lower end of the first connecting plate.

[0008] A further technical solution of this utility model is that the upper end of the first connecting plate is provided with a first hole plate for installing screws.

[0009] A further technical solution of this utility model is that a first folding plate is provided on the top of the first side plate, and at least one first recess adapted to the first perforated plate is provided on the first folding plate.

[0010] A further technical solution of this utility model is that at least one mounting plate is provided on the first tray, and the mounting plate is provided with a screw hole adapted to the power fan.

[0011] A further technical solution of this utility model is that the second bracket includes a second support plate and a second connecting plate, the upper end of the second connecting plate is connected to the second side plate, and the second support plate is fixed to the lower end of the second connecting plate.

[0012] A further technical solution of this utility model is that the second tray is provided with screw holes adapted to the power fan.

[0013] A further technical solution of this utility model is that the second tray extends along the width direction of the power fan; and the second tray blocks a portion of the air outlet of the power fan.

[0014] A further technical solution of this utility model is that the obstruction portion on the second tray does not exceed 1 / 2 of the area of ​​the air outlet.

[0015] A further technical solution of this utility model is that the upper end of the second connecting plate is provided with a second hole plate for installing screws.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model provides a computer power supply fan mounting device, which includes a first bracket and a second bracket. The first bracket supports the bottom of one end of the power supply fan, and the second bracket supports the bottom of the other end. This distributes the weight of the power supply fan across the brackets, ensuring good load-bearing capacity. Furthermore, since both the first and second brackets are located within the outer frame, the computer power supply appears neat and screwless. Additionally, the second bracket partially obstructs the fan's exhaust vent. This obstruction increases the airflow velocity at the exhaust vent, providing better heat dissipation for the main heat-generating components below the vent and extending the power supply's lifespan.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1 to 4 As shown, the computer power supply fan fixing device provided in this embodiment includes a first bracket 1 and a second bracket 2. The first bracket 1 supports the bottom of one end of the power supply fan 3, and the second bracket 2 supports the bottom of the other end of the power supply fan 3. By supporting the power supply fan 3 from both ends through the first bracket 1 and the second bracket 2, the weight of the power supply fan 3 is distributed to the brackets. The first bracket 1 is fixed to the first side plate 41 of the outer frame 4 of the computer power supply, and the second bracket 2 is fixed to the second side plate 42 of the outer frame 4 of the computer power supply. Thus, the power supply fan 3 is indirectly hung on the first side plate 41 and the second side plate 42 of the outer frame 4. Both the first bracket 1 and the second bracket 2 are located inside the outer frame 4. Correspondingly, the power supply fan 3 itself is also located inside the outer frame 4. This eliminates the need for screws to fix the computer power supply to the air intake plate 431 of the outer frame 4. Specifically, the middle part of the outer casing 43 is the air intake plate 431, which also includes two side plates. In summary, the computer power supply has a clean appearance and is screwless.

[0028] The first bracket 1 includes a first support plate 11 and a first connecting plate 12. The upper end of the first connecting plate 12 is connected to the first side plate 41, and the first support plate 11 is fixed to the lower end of the first connecting plate 12. The first connecting plate 12 is parallel to the side plate of the first side plate 41 and is in close contact with the first side plate 41, thereby preventing the first bracket 1 from affecting the internal volume of the outer frame 4. The first support plate 11 is fixed to the first side plate 41 by the first connecting plate 12. Furthermore, the upper end of the first connecting plate 12 is provided with a first hole plate 13 for installing screws. The screws pass through the screw holes on the first hole plate 13 to fix the first hole plate 13. More preferably, in order to better adapt the top of the first side plate 41 to the first hole plate 13, a first folding plate 411 is provided on the top of the first side plate 41. The first folding plate 411 is provided with at least one first recess 412 that adapts to the first hole plate 13. Specifically, the two first hole plates 13 are placed into the two corresponding first recesses 412, and each first hole plate 13 is fixed in the corresponding first recess 412 by two screws that pass through the two first hole plates 13 respectively. When the outer cover 43 of the outer frame 4 is covered, it covers the two screws. In this way, not only will the screws not be exposed, but no matter how the power fan 3 loosens the screws, the screws are also restricted in the first recess 412 and cannot move.

[0029] The second support plate 21 can be configured to have the same shape as the first support plate 11, that is, the first support plate 11 and the second support plate 21 are symmetrically distributed. The second bracket 2 includes the second support plate 21 and the second connecting plate 22. The upper end of the second connecting plate 22 is connected to the second side plate 42, and the second support plate 21 is fixed to the lower end of the second connecting plate 22. The upper end of the second connecting plate 22 is provided with a second hole plate 23 for mounting screws. The top of the second side plate 42 is provided with a second folding plate 421, and the second folding plate 421 is provided with at least one second recess 422 that is adapted to the second hole plate 23. The assembly method of the second hole plate 23 and the second recess 422 is similar to that of the first hole plate 13 and the first recess 412, that is, the two are symmetrically arranged, so it will not be described in detail here. More preferably, the first support plate 11 is provided with at least one mounting piece 111, and the mounting piece 111 is provided with a screw hole 5 adapted to the power fan 3. Similarly, the second bracket 21 is also provided with symmetrically distributed mounting pieces 111. That is, in this embodiment, four symmetrically distributed mounting pieces 111 are used. Then, the four corners of the power fan 3 are locked by the four screw holes 5 on the four mounting pieces 111, so that the power fan 3 is fixed on the two brackets.

[0030] Example 2

[0031] like Figure 5As shown, the computer power supply fan fixing device provided in this embodiment includes a first bracket 1 and a second bracket 2. The first bracket 1 is used to support the bottom of one end of the power supply fan 3, and the second bracket 2 is used to support the bottom of the other end of the power supply fan 3. The first bracket 1 is fixed on the first side plate 41 of the outer frame 4 of the computer power supply, and the second bracket 2 is fixed on the second side plate 42 of the outer frame 4 of the computer power supply. Both the first bracket 1 and the second bracket 2 are located inside the outer frame 4.

[0032] The difference between Example 1 and Example 2 is as follows:

[0033] The second support plate 21 can be configured to have a different shape from the first support plate 11. The second support plate 21 extends to act as a baffle at the air outlet 31 of the power supply fan 3. In this case, the second support plate 21 is provided with two screw holes 5 that are compatible with the power supply fan 3, similar to the description in Embodiment 1. These screw holes 5, along with the two mounting plates 111 of the first bracket, lock the four corners of the power supply fan 3. More preferably, the second support plate 21 extends along the width direction of the power supply fan 3 and partially blocks the air outlet 31 of the power supply fan 3, acting as a baffle at the air outlet 31. When the air outlet 31 is blocked, the airflow speed at the air outlet 31 increases, providing better heat dissipation for the main heat-generating components of the computer power supply below the air outlet 31 and extending the lifespan of the computer power supply. More preferably, when the blocked portion on the second support plate 21 does not exceed half the area of ​​the air outlet 31, it not only has a better heat dissipation effect on the main heat-generating components but also has minimal impact on the normal airflow of the power supply fan 3.
