Description

Technical Field

[0001] This utility model relates to the field of dustproof mesh technology, and in particular to a cabinet air intake dust louver device. Background Technology

[0002] A server rack is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. Primarily made of metal, it serves to protect the internal electrical or electronic equipment from dust and water. However, electrical or electronic equipment generates heat during operation, necessitating heat dissipation within the rack to prevent overheating and potential burnout. Current common cooling methods involve creating multiple vents on the rack's surface to improve airflow and dissipate heat. However, this introduces new problems. The vibrations generated by the electrical or electronic equipment produce noise, some of which escapes through the vents, causing significant noise pollution and inconvenience to those in the rack's environment. Utility Model Content

[0003] The purpose of this utility model is to provide a cabinet air intake dust louver device that reduces the sound emitted from inside the cabinet while ensuring ventilation and heat dissipation, thereby reducing the impact of noise.

[0004] The technical solution adopted by the cabinet air intake dust louver device disclosed in this utility model is: A cabinet air intake dust louver device includes a mounting frame for installation on the surface of the cabinet. The mounting frame has a plurality of arc-shaped baffles in the middle, and there are ventilable intervals between the plurality of arc-shaped baffles. The arc-shaped baffles have a structure in which the inner side of the mounting frame bends downward toward the outer side, and the lower end of the arc-shaped baffles has a hook portion extending toward the inner side of the mounting frame.

[0005] As a preferred embodiment, the hook portion is horizontally arranged, and the upper end of the arc-shaped baffle is provided with a protrusion, the uppermost end of the protrusion and the lowermost end of the hook portion are located on the same horizontal line.

[0006] As a preferred embodiment, the middle part of the mounting frame protrudes inward, and the lower end of the arc-shaped baffle is located on the same plane as the outer side of the mounting frame.

[0007] As a preferred embodiment, the inner side of the mounting frame is also provided with a dustproof net, which is set corresponding to the arc-shaped baffle, and the dustproof net and the mounting frame are detachable.

[0008] As a preferred embodiment, the inner side of the mounting frame is provided with a buckle, there is a gap between the buckle and the arc-shaped baffle, and the dustproof net is inserted between the buckle and the arc-shaped baffle.

[0009] As a preferred embodiment, the dustproof net is provided with a handle at the upper end, and the handle protrudes from the side away from the mounting frame.

[0010] The beneficial effects of the cabinet air intake dust louver device disclosed in this utility model are as follows: the dustproof mesh plate uses the mounting frame as the base, with multiple arc-shaped baffles in the middle, and ventilation gaps between adjacent baffles. The arc-shaped baffles curve downwards and then inwards from the inside of the cabinet, forming a hook-shaped part extending inwards from the lower end. This structure achieves a synergistic effect in both ventilation and noise reduction: during heat dissipation, hot air inside the cabinet enters the cabinet along the gaps between the arc-shaped baffles, achieving air circulation and carrying away the heat from inside the cabinet. Regarding noise reduction: when sound waves propagate from inside the cabinet outwards, they undergo multiple reflections on the continuous curved surface of the arc-shaped baffles, with some energy returning to the cabinet. Simultaneously, the hook-shaped part forms a reverse protrusion, disrupting the straight-line propagation of sound waves and causing phase differences that lead to partial cancellation of sound waves. This ensures that ventilation and heat dissipation are achieved while reducing noise transmission from inside the cabinet. Attached Figure Description

[0013] Figure 3 This is a schematic diagram of the structure of the cabinet air intake and dust louver device of this utility model. Detailed Implementation

[0014] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2 A cabinet air intake dust louver device includes a mounting frame 10 for mounting on the surface of the cabinet. The mounting frame 10 has a plurality of arc-shaped baffles 20 in the middle, and there are ventilable intervals between the plurality of arc-shaped baffles 20. The arc-shaped baffles 20 have a structure in which the inner side of the mounting frame 10 bends downward toward the outer side, and the lower end of the arc-shaped baffles 20 has a hook portion 21 extending toward the inner side of the mounting frame 10.

[0015] The dustproof mesh panel uses the mounting frame 10 as its base, with multiple arc-shaped baffles 20 in the middle. Ventilation gaps are left between adjacent baffles. The arc-shaped baffles 20 curve downwards and then inwards from the inside of the cabinet, forming a hook-shaped section 21 extending inwards from the lower end. This structure achieves a synergistic effect in both ventilation and noise reduction: During heat dissipation, hot air inside the cabinet enters along the gaps between the arc-shaped baffles 20, achieving air circulation and carrying away the heat from inside the cabinet. Regarding noise reduction: when sound waves propagate from inside the cabinet outwards, they undergo multiple reflections on the continuous curved surface of the arc-shaped baffles 20, with some energy returning to the cabinet. Simultaneously, the hook-shaped section 21 forms a reverse protrusion, disrupting the straight-line propagation of sound waves. This phase difference causes some sound waves to cancel each other out, thus ensuring that ventilation and heat dissipation are achieved while reducing noise transmission from inside the cabinet.

[0016] The hook portion 21 is horizontally positioned, and the upper end of the arc-shaped baffle 20 is provided with a protrusion 22. The uppermost end of the protrusion 22 and the lowermost end of the hook portion 21 are on the same horizontal line. The protrusion 22 is used to increase the rebound and refraction effect of sound waves, thereby further improving the noise reduction purpose. At the same time, it can also better play the purpose of dust prevention, preventing dust from flowing along the surface of the arc-shaped baffle 20, and blocking it at the connection between the protrusion 22 and the arc-shaped baffle 20, reducing the amount of dust entering the cabinet.

[0017] The middle part of the mounting frame 10 protrudes inward 22, and the lower end of the arc-shaped baffle 20 is on the same plane as the outer side of the mounting frame 10, thereby ensuring that the surface of the mounting frame 10 is flat after it is installed on the rack surface, while providing space for the arc-shaped baffle 20.

[0018] Please refer to Figure 3 In the above scheme, a dustproof net 30 is also provided on the inner side of the mounting frame 10. The dustproof net 30 is set corresponding to the arc-shaped baffle 20. The dustproof net 30 and the mounting frame 10 are detachable. The dustproof net 30 can further improve the dustproof effect and intercept the dust entering between the arc-shaped baffle 20. The detachable structure makes it convenient for people to clean the dustproof net 30. At the same time, the dustproof net 30 can also further block the transmission of sound.

[0019] The mounting frame 10 has a buckle 11 on its inner side. There is a gap between the buckle 11 and the arc-shaped baffle 20. The dustproof net 30 is inserted between the buckle 11 and the arc-shaped baffle 20. The dustproof net 30 has a handle 31 at its upper end. The handle 31 protrudes away from the mounting frame 10. The buckle 11 fixes and limits the dustproof net 30 so that it fits snugly against the mounting frame 10. The dustproof net 30 can be pulled out from the top using the handle 31, achieving a detachable effect.

[0020] This utility model provides a cabinet air intake dust louver device. The dust filter plate uses a mounting frame as its base, with multiple arc-shaped baffles in the middle. Ventilation gaps are left between adjacent baffles. The arc-shaped baffles curve downwards and then inwards from the inside of the cabinet, forming a hook-shaped part extending inwards from the lower end. This structure produces a synergistic effect in terms of ventilation and heat dissipation, as well as noise reduction: During heat dissipation, hot air inside the cabinet enters the cabinet along the gaps between the arc-shaped baffles, achieving air circulation and carrying away the heat inside the cabinet. In terms of noise reduction: when sound waves propagate from inside the cabinet outwards, they undergo multiple reflections on the continuous curved surface of the arc-shaped baffles, with some energy being reflected back into the cabinet. At the same time, the hook-shaped part forms a reverse protrusion, disrupting the straight-line propagation of sound waves. The phase difference causes some sound waves to cancel each other out, thus ensuring that ventilation and heat dissipation are achieved while reducing the noise transmission from inside the cabinet.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
