Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for computer rooms, and in particular to a noise reduction device for computer rooms. Background Technology

[0002] Computer rooms contain a large number of electronic devices, such as servers, storage devices, and network switches. These devices are equipped with cooling fans, which generate aerodynamic noise when running at high speeds. For example, multiple fans inside a server continuously operate at speeds of thousands of revolutions per minute to ensure the cooling of server components, generating noise. At the same time, storage devices generate mechanical noise from the high-speed rotation of disks and the movement of read / write heads when reading and writing data. Transformers and inductors in power supply equipment vibrate due to electromagnetic forces during operation, thus emitting electromagnetic noise. With the development of electronic and acoustic technologies, computer room noise reduction technologies have become increasingly diversified. Products such as soundproof enclosures, sound-absorbing materials, and silencers specifically designed for computer room equipment have emerged, effectively reducing noise at different frequencies. This reduction in computer room noise provides a relatively quiet working environment for staff, helping to improve their work enthusiasm and efficiency. At the same time, noise reduction measures protect equipment, reduce the probability of equipment failure, lower computer room maintenance costs, and ensure the stable operation of the computer room.

[0003] The structure of a computer room noise reduction device includes a shell, sound-absorbing materials, sound insulation panels, silencers, vibration dampers, a ventilation system, and seals. In a noisy computer room environment, it is difficult for staff to accurately judge whether the equipment is operating abnormally by sound. The computer room noise reduction device improves the acoustic environment inside the computer room, allowing staff to hear the normal operation sound and abnormal sound of the equipment more clearly. This helps to detect potential equipment failures in a timely manner and improves the timeliness and accuracy of equipment maintenance. However, when the existing computer room is not well sealed, especially the windows that require ventilation, the internal noise can easily spread to the outside of the computer room through various gaps and holes, causing noise and making the noise reduction measures ineffective. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a noise reduction device for computer rooms, which aims to improve the problem that when the internal sealing of the existing computer room is poor, especially the poor sealing of the windows that require ventilation, the internal noise can easily spread to the outside of the computer room through various gaps and holes, causing noise and making it impossible for soundproofing measures to effectively reduce noise.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a computer room noise reduction device, comprising a computer room body, window frames fixedly connected to both the left and right sides of the computer room body, a fixing block fixedly connected to the front end of an adjacent side of the window frame, a glass window fixedly connected to the rear inside of the window frame, a sliding track fixedly connected to the bottom inside of the window frame, a glass frame slidably connected to the top of the sliding track, a sealing strip fixedly connected to the rear side of the glass frame, hollow tempered glass fixedly connected inside the glass frame, a support block fixedly connected to the front end of an adjacent side of the glass frame, a buckle rotatably connected to the top of the support block, the front end of the buckle engaging with the top of the fixing block, and a noise reduction mechanism provided inside the computer room body for noise reduction of the computer room.

[0006] As a further description of the above technical solution:

The bottom of the perforated metal sound-absorbing panel is fixedly connected to the top of the main body of the computer room. A precast concrete slab is fixedly connected to the top of the perforated metal sound-absorbing panel. Mineral wool boards are fixedly connected to all four sides of the main body of the computer room. A metal composite board is fixedly connected to the opposite side of the mineral wool board. An elastic pad is fixedly connected to the bottom of the main body of the computer room. A shock-absorbing pad is fixedly connected to the bottom of the elastic pad.

[0008] As a further description of the above technical solution:

[0009] A handle is fixedly connected to the rear end of each adjacent side of the glass frame, and an anti-slip pad is fixedly connected to the top of the shock-absorbing pad.

[0010] As a further description of the above technical solution:

[0011] A warning sign is fixedly connected to the top front side of the main body of the computer room, and two door frames are rotatably connected to the front side of the main body of the computer room.

[0012] As a further description of the above technical solution:

[0013] Each of the two observation windows is fixedly connected to the center of the front side of the door frame, and both observation windows are designed symmetrically.

[0014] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] Each adjacent side of the door frame is fixedly connected with a sealing strip, and the interior of the hollow tempered glass is fixedly connected with a damping membrane.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the window frame is sealed by sliding the glass frame on the sliding track, which ensures that the gap between the window frame and the glass frame is tightly filled. Combined with the sealing strip, the glass window and the glass frame are sealed, forming a relatively closed space. It is difficult for sound to leak out through these well-sealed gaps during the propagation process, effectively preventing external noise from entering the computer room and preventing noise from the computer room from being transmitted out. The sealing structure cuts off the path of low-frequency sound propagation.

[0022] 2. In this utility model, the perforated metal sound-absorbing panel can reduce the high-frequency noise generated by the operation of equipment in the computer room. The mineral wool board absorbs sound energy through the viscous resistance of the air and the friction between the fiber and the sound, and has a good absorption effect on mid- and low-frequency sounds. The metal composite panel can effectively block the sound transmission inside and outside the computer room. The elastic pad and shock-absorbing pad further enhance the shock absorption effect of the entire top structure and provide additional shock absorption capacity. By reducing the transmission of vibration, the noise level in the computer room is indirectly reduced. Attached Figure Description

[0040] Working principle: The window frame 3 is sealed by the sliding of the glass frame 7 on the sliding track 6, which ensures that the gap between the window frame 3 and the glass frame 7 is tightly filled. Combined with the sealing strip 8, the glass window 5 and the glass frame 7 are sealed, forming a relatively closed space. It is difficult for sound to leak out through these well-sealed gaps during the propagation process, effectively preventing external noise from entering the computer room and preventing noise from the computer room from being transmitted out. The sealing structure cuts off the path of low-frequency sound propagation, which significantly enhances the isolation effect of low-frequency noise. At the same time, the position of the glass frame 7 is fixed by the engagement of the rotating buckle 11 and the fixing block 4, which can keep the position of the glass frame 7 within the window frame 3 and maintain a stable sealing effect.

[0041] The perforated metal sound-absorbing panel 201 on the top of the main body 1 of the computer room effectively reduces the high-frequency noise generated by the operation of the equipment in the computer room. The precast concrete slab 202 on top of the perforated metal sound-absorbing panel 201 itself has certain sound insulation and heat insulation properties, which can block external sound from entering the computer room, especially having a good blocking effect on low-frequency sound. The mineral wool board 203 absorbs sound energy through the viscous resistance of air and the friction between fibers and sound, and has a good absorption effect on mid- and low-frequency sound. The metal composite panel 204 can effectively block the transmission of sound inside and outside the computer room, reducing the intensity of external noise entering the computer room, and also reducing Noise from equipment inside the computer room propagates outwards. The elastic pad 205 can convert vibration energy into elastic potential energy and store it, then release it slowly, thereby reducing the direct transmission of vibration waves to the internal structure and equipment of the computer room. This vibration reduction effect can significantly reduce the noise in the computer room caused by vibration. The vibration damping pad 206 further enhances the vibration reduction effect of the entire top structure. In particular, for some local vibration sources and high-frequency vibrations, the vibration damping pad 206 can give full play to its elastic advantages and provide additional vibration reduction capacity. By reducing the propagation of vibration, it indirectly reduces the noise level in the computer room and improves the acoustic environment quality of the computer room.
