[0038] Embodiment 1

[0039] like Figure 1 As shown, the first aspect of the present application provides a noise reduction structure, including a mounting portion 1, a first barrier portion 2 and a second barrier portion 3; the first barrier portion 2 is arranged on the mounting portion 1; the second barrier portion 3 is arranged on the mounting portion 1 and is spaced apart from the first barrier portion 2, and the second barrier portion 3, the first barrier portion 2 and the mounting portion 1 form a noise reduction space 4; wherein the first barrier portion 2, the second barrier portion 3 and the noise reduction space 4 are used for attenuating noise energy.

[0040] Specifically, the mounting part 1 can be assembled in the chassis of the server while carrying and installing the first barrier part 2 and the second barrier part 3, so that the noise reduction structure is arranged on the path where the noise generated by the fan is transmitted to the hard disk. The mounting part 1 can be a plate-shaped or sheet-shaped object. By setting threaded holes, positioning pin holes, rivet holes, etc., the mounting part 1 can be installed in the chassis of the server by corresponding screws, positioning pins, rivets, etc. The present application has a simple structure, is easy to install, and has low cost. The mounting part 1 can be integrally formed with the same material as the first barrier part 2 and the second barrier part 3, or it can be combined as a separate part with the first barrier part 2 and the second barrier part 3 through welding, assembly and other processes, so that the second barrier part 3, the first barrier part 2 and the mounting part 1 can form a noise reduction space 4 for attenuating noise energy.

[0041] The first barrier part 2 and the second barrier part 3 can be in the shape of a straight long plate, an arc plate, or a serpentine plate. The specific shape is not limited. The specific structural form of the first barrier part 2 and the second barrier part 3 is determined according to the required noise reduction effect in the chassis and the relative position relationship between the fan and the hard disk. It can also be adjusted accordingly for the performance parameters of different types of fans and hard disks to achieve different noise reduction effects. The sound waves of the noise will be partially reflected when contacting the first barrier part 2 and the second barrier part 3, thereby attenuating the energy, and the first barrier part 2 and the second barrier part 3 can be provided with sound-absorbing holes and other structures on both sides of the noise propagation path so that the noise can be reflected in the groove wall of the sound-absorbing holes to achieve energy attenuation and achieve the purpose of noise reduction. The surface of the first barrier part 2 and the second barrier part 3 can also be coated with damping coatings, bio-fiber sound-absorbing coatings and other sound-absorbing coatings to further enhance the noise reduction effect.

[0042] The second barrier part 3 is spaced apart from the first barrier part 2, so that a noise reduction space 4 can be formed between the second barrier part 3, the first barrier part 2 and the mounting part 1, so that the first barrier part 2, the second barrier part 3 and the noise reduction space 4 are at least partially located on the path where the noise generated by the fan is transmitted to the hard disk. The sound waves of the noise will be reflected by the side walls of the space for many times in the noise reduction space 4, causing energy attenuation. At the same time, when the sound waves propagate in the noise reduction space 4, they will rub against the air in the space, causing energy attenuation. Moreover, since the noise reduction space 4 and the first barrier part 2 and the second barrier part 3 serve as different sound propagation media, the sound waves of the noise will be refracted when passing through the first barrier part 2, the noise reduction space 4 and the second barrier part 3 in sequence, thereby changing the original propagation direction of the sound waves, resulting in an increase in the sound wave propagation path so that the sound wave energy attenuation increases, thereby achieving the purpose of noise reduction.

[0043] The noise reduction structure of the present application composed of the first barrier part 2, the second barrier part 3 and the mounting part 1 can be made of thermoplastic plastics, resin materials, etc. using 3D printing, injection molding, extrusion molding and other technologies, or the first barrier part 2, the second barrier part 3 and the mounting part 1 using the above materials can be welded using hot melt puncture welding or vibration friction welding. The first barrier part 2, the second barrier part 3 and the mounting part 1 can also be welded by metal materials, or the noise reduction structure of the present application can be made by using metal powder using metal 3D printing technology. The second barrier part 3, the first barrier part 2 and the mounting part 1 form a noise reduction space 4 for attenuating noise energy.

[0044] A first aspect of the present application provides a noise reduction structure, including a mounting portion 1, a first barrier portion 2 and a second barrier portion 3; the first barrier portion 2 is arranged on the mounting portion 1; the second barrier portion 3 is arranged on the mounting portion 1 and is spaced apart from the first barrier portion 2, and the second barrier portion 3, the first barrier portion 2 and the mounting portion 1 form a noise reduction space 4; wherein the first barrier portion 2, the second barrier portion 3 and the noise reduction space 4 are used for attenuating noise energy. The noise reduction structure of the present application is installed in the chassis and is located on the path where the noise generated by the fan is transmitted to the hard disk. On the first hand, the sound waves of the noise will be partially reflected when contacting the first barrier part 2 and the second barrier part 3, thereby attenuating the energy; on the second hand, since the air in the noise reduction space 4 and the first barrier part 2 and the second barrier part 3 are different sound propagation media, the sound waves of the noise will be refracted when passing through the first barrier part 2, the noise reduction space 4 and the second barrier part 3 in sequence, thereby changing the original propagation direction of the sound wave, resulting in the growth of the sound wave propagation path to increase the attenuation of the sound wave energy; on the third hand, the sound waves of the noise will be reflected with the side walls of the space many times in the noise reduction space 4, causing energy attenuation, and at the same time, when the sound waves propagate in the noise reduction space 4, they will rub against the air in the space, thereby causing energy attenuation. In summary, through the application of the present application, the energy of the noise in the chassis of the server is effectively attenuated during the propagation process, the purpose of noise reduction is achieved, and the read and write speed of the hard disk in the chassis is guaranteed.

[0045] like Figure 1 As shown, in some embodiments, the first blocking portion 2 and the second blocking portion 3 are both vertically arranged on the same side of the mounting portion 1 to form a noise reduction space 4.

[0046] Specifically, in order to enable the first blocking part 2, the second blocking part 3 and the noise reduction space 4 to provide a better noise reduction effect and facilitate the arrangement of the noise reduction structure of the present application in the chassis, the present application sets the first blocking part 2 and the second blocking part 3 to be vertically arranged on the same side of the mounting part 1 to form the noise reduction space 4. The vertical arrangement enables the first blocking part 2 and the second blocking part 3 to provide a reflection surface perpendicular to the noise propagation path on the path where the noise generated by the fan is transmitted to the hard disk, so as to ensure the maximum noise reflection effect. And the vertical arrangement enables the noise reduction space 4 surrounded by the first blocking part 2, the second blocking part 3 and the mounting part 1 to have inner walls perpendicular to the mounting part 1 on both sides of the noise propagation path, so that the noise can be fully reflected along the inner walls on both sides of the noise reduction space 4 to attenuate the energy, thereby bringing a better noise reduction effect. At the same time, the first blocking part 2 and the second blocking part 3 are both vertically arranged on the same side of the mounting part 1, which is convenient for connection and fixation from the process point of view, and better control of design parameters and structural quality, and can facilitate the arrangement and installation of the space in the chassis.

[0047] like Figure 2As shown, in some embodiments, the side of the first barrier portion 2 facing the noise reduction space 4 is the inner wall of the first barrier portion 2, and a plurality of first recessed portions 21 are evenly spaced on the inner wall of the first barrier portion 2, and the openings of the first recessed portions 21 face the second barrier portion 3.

[0048] Specifically, a plurality of first recessed portions 21 with openings facing the second barrier portion 3 are evenly spaced on the inner side wall of the first barrier portion 2. The provision of the first recessed portions 21 increases the volume of the noise reduction space 4, so that the noise can more fully rub against the air in the noise reduction space 4 to attenuate energy. The side walls in the first recessed portions 21 serve as the additional spatial side walls of the noise reduction space 4, which can increase the reflection surfaces for the noise to propagate in the noise reduction space 4, thereby bringing about a better noise reduction effect.

[0049] like Figure 3 As shown, in some embodiments, the side of the first barrier portion 2 facing away from the noise reduction space 4 is the outer wall of the first barrier portion 2, and a plurality of second recessed portions 22 are evenly spaced apart on the outer wall of the first barrier portion 2. The setting position of the second recessed portion 22 on the first barrier portion 2 corresponds to the middle part of two adjacent first recessed portions 21, and the opening of the second recessed portion 22 faces away from the second barrier portion 3.

[0050] Specifically, the outer wall of the first barrier portion 2 which is away from the noise reduction space 4 is evenly spaced to provide a plurality of second recessed portions 22 with openings away from the second barrier portion 3, so that on the path where the fan-generated noise is transmitted to the hard disk, the outer wall of the first barrier portion 2 as a noise reduction structure is the first side that contacts the noise. Due to the provision of the second recessed portions 22, the first barrier portion 2 has a plurality of spaces that can reflect and attenuate the energy of the noise. Therefore, on the basis of the first barrier portion 2 reflecting and refracting the noise, the first barrier portion 2 can also attenuate part of the noise energy through the second recessed portions 22, thereby enhancing the noise reduction effect.

[0051] In order to make the first recessed portion 21 and the second recessed portion 22 on the first barrier portion 2 cooperate to enhance the noise reduction effect, enhance the aesthetics and regularity of the structure, and facilitate production and manufacturing, the present application arranges the second recessed portion 22 on the first barrier portion 2 at a position corresponding to the middle of two adjacent first recessed portions 21, so that the first recessed portion 21 and the second recessed portion 22 do not interfere with each other, but can attenuate the energy of noise at different positions of the first barrier portion 2. At the same time, due to the interspersed arrangement, the first barrier portion 2 does not need to be very thick to complete the arrangement of the first recessed portion 21 and the second recessed portion 22. Finally, the arrangement of the first recessed portion 21 and the second recessed portion 22 makes the first barrier portion 2 present a serpentine structure.

[0052] like Figure 4 and Figure 5As shown, in some embodiments, the second blocking part 3 includes a plurality of blocking units 31, the blocking units 31, the first blocking part 2 and the mounting part 1 enclose a noise reduction subspace 41, and the plurality of noise reduction subspaces 41 constitute a noise reduction space 4; the blocking unit 31 includes a blocking body 311, a first extension body 312 connected to one side of the blocking body 311 and a second extension body 313 connected to the other side of the blocking body 311, and the plurality of blocking units 31 are interconnected through the first extension body 312 and the second extension body 313; the blocking body 311 includes a first blocking body 3111, a second blocking body 3112 and a third blocking body 3113, the first ends of the first blocking body 3111 and the third blocking body 3113 are respectively connected to the two ends of the second blocking body 3112, the second end of the first blocking body 3111 is connected to the first extension body 312, and the second end of the third blocking body 3113 is connected to the second extension body 313.

[0053] Specifically, the second barrier portion 3 is composed of a plurality of barrier units 31 , and a plurality of noise reduction subspaces 41 are enclosed by the plurality of barrier units 31 , the first barrier portion 2 and the mounting portion 1 , which together constitute a noise reduction space 4 between the first barrier portion 2 and the second barrier portion 3 . The blocking unit 31 is composed of a blocking body 311, a first extension body 312 and a second extension body 313. The blocking body 311 includes a first blocking body 3111, a second blocking body 3112 and a third blocking body 3113, and the first ends of the first blocking body 3111 and the third blocking body 3113 are respectively connected to the two ends of the second blocking body 3112, the second end of the first blocking body 3111 is connected to the first extension body 312, and the second end of the third blocking body 3113 is connected to the second extension body 313. A noise reduction subspace 41 with sufficient volume is formed between the first blocking part 2 and each blocking unit 31, and then energy attenuation is achieved through sufficient friction of noise in multiple noise reduction subspaces 41 and reflection along the side walls of the space in multiple noise reduction subspaces 41 to achieve the purpose of noise reduction. At the same time, when the sound waves of the noise pass through the first barrier part 2 and multiple noise reduction subspaces 41 in sequence, refraction will occur because the air in the first barrier part 2 and the noise reduction subspace 41 is a different sound propagation medium, thereby changing the original propagation direction of the sound wave, resulting in an increase in the sound wave propagation path and increasing the attenuation of the sound wave energy.

[0054] It should be noted that the plurality of barrier units 31 can be thermoplastic plastics, resin materials, etc., and can be integrally formed into the second barrier portion 3 using 3D printing, injection molding, extrusion molding, and other technologies. Alternatively, the plurality of barrier units 31 can be welded together to form the second barrier portion 3 by hot melt puncture welding or vibration friction welding, and the like, without specific limitations. The barrier unit 31 includes a barrier body 311, a first extension body 312 connected to one side of the barrier body 311, and a second extension body 313 connected to the other side of the barrier body 311. The barrier body and the first extension body 313 and the second extension body 313 can be integrally formed by 3D printing, injection molding, extrusion molding, and the like, or can be welded, and the specific limitations are not limited. Similarly, the first barrier body 3111, the second barrier body 3112, and the third barrier body 3113 can also form the barrier body 311 in the above manner, and the specific limitations are not specific.

[0055] like Figure 5 As shown, in some embodiments, the first barrier 3111, the second barrier 3112 and the third barrier 3113 are each provided with a third recess 3114 on the side facing away from the noise reduction subspace 41, and the opening of the third recess 3114 faces away from the noise reduction subspace 41; the first barrier 3111, the second barrier 3112 and the third barrier 3113 are each provided with a fourth recess 3115 on the side facing the noise reduction subspace 41, the fourth recess 3115 is arranged at a position separated from the third recess 3114, and the opening of the fourth recess 3115 faces the noise reduction subspace 41.

[0056] Specifically, in order to increase the effect of attenuating noise energy between multiple interconnected barrier units 31, the present application sets a third recessed portion 3114 with an opening away from the noise reduction subspace 41 on the side of the first barrier 3111 and the third barrier 3113 away from the noise reduction subspace 41, so that the volume of the space enclosed by the first barrier 3111 and the third barrier 3113 of the two adjacent barrier units 31 is increased due to the setting of the third recessed portion 3114, and the number of side walls of the space is increased, which increases the reflection surface of the noise propagating in the noise reduction subspace 41, facilitates multiple reflections of the noise on the inner wall of the space, and can more fully rub against the air in the space, thereby improving the noise energy attenuation effect. The third recessed portion 3114 is set on the side of the second barrier 3112 away from the noise reduction subspace 41, so that the third recessed portion 3114 at this position can also provide a space at the end of the noise propagation path of the noise reduction structure example that can make the noise reflect and rub against the air to attenuate energy, thereby bringing further noise reduction effect.

[0057] The first barrier 3111, the second barrier 3112 and the third barrier 3113 are all provided with a fourth recessed portion 3115 with an opening facing the noise reduction subspace 41 on one side thereof facing the noise reduction subspace 41, and the fourth recessed portion 3115 is provided at a position spaced from the third recessed portion 3114. The fourth recessed portion 3115 can increase the volume of the noise reduction subspace 41 corresponding to each barrier unit 31, and further increase the spatial side wall of the noise reduction subspace 41, and increase the reflection surface of the noise propagating in the noise reduction subspace 41, so that the noise can more fully rub against the air in the noise reduction subspace 41 to attenuate the energy, and at the same time can fully reflect in the noise reduction subspace 41 having the fourth recessed portion 3115 as the side wall, thereby improving the energy attenuation effect of the noise, that is, the noise reduction effect.

[0058] In one embodiment, the third recessed portion 3114 on the first barrier body 3111 is arranged near the connection position between the first barrier body 3111 and the first extension body 312, the third recessed portion 3114 on the second barrier body 3112 is located in the middle of the second barrier body 3112, the third recessed portion 3114 on the third barrier body 3113 is arranged near the connection position between the second end of the third barrier body 3113 and the second extension body 313, the fourth recessed portion 3115 is arranged at a position separated from the third recessed portion 3114, and the opening of the third recessed portion 3114 is away from the noise reduction subspace 41, and the opening of the fourth recessed portion 3115 is toward the noise reduction subspace 41.

[0059] In some embodiments, there are multiple first barrier parts 2 and multiple second barrier parts 3, and the multiple first barrier parts 2 and multiple second barrier parts 3 are arranged on the mounting part 1 at intervals, and the multiple second barrier parts 3, multiple first barrier parts 2 and the mounting part 1 enclose multiple noise reduction spaces 4.

The structural shapes of the first barrier parts 2 and the second barrier parts 3 can be the same; the structural shapes of the first barrier parts 2 and the second barrier parts 3 can also be different; the plurality of first barrier parts 2 and the plurality of second barrier parts 3 can be arranged symmetrically, and the plurality of first barrier parts 2 and the plurality of second barrier parts 3 can also be arranged in a mirror image, and there is no specific limitation, so as to achieve the required noise reduction effect and meet the arrangement space in the chassis.

The interval arrangement order of the first barrier parts 2 and the second barrier parts 3 on the mounting part is the first barrier part 2, the second barrier part 3, the second barrier part 3 and the first barrier part 2. The two second barrier parts 3, the two first barrier parts 2 and the mounting part 1 enclose three noise reduction spaces 4.

[0063] In some embodiments, the mounting portion 1 is provided with an assembly component, which is used to fix the mounting portion 1 , and the noise reduction space 4 is used to increase the path of noise transmission to attenuate the noise energy.

[0065] Embodiment 2

[0066] A second aspect of the present application provides a server, including a chassis and the above-mentioned noise reduction structure, wherein a hard disk and a fan are arranged at intervals in the chassis; the noise reduction structure is arranged in the chassis and is at least partially located on the path where the noise generated by the fan is transmitted to the hard disk.

[0067] Specifically, please refer to the first embodiment for the specific structure of the noise reduction structure, which will not be described in detail here.

[0068] Specifically, the noise generated by the rotation of the fan causes the chassis to be in a high-pitched and high-volume noise environment and causes disturbance of the air in the chassis, thereby vibrating the hard disk and interfering with the read and write actions of the hard disk, thereby affecting the read and write speed. The present application achieves noise energy attenuation by setting a noise reduction structure in the chassis and at least partially located on the path where the noise generated by the fan is transmitted to the hard disk, thereby ensuring the normal operation of the hard disk and thus ensuring the normal operation of the server. The noise reduction structure set in the server of the present application can be adjusted accordingly to the performance parameters of different types of fans and hard disks to achieve different noise reduction effects, and the specific structural form of the noise reduction structure can also be adjusted according to the noise reduction effect required in the chassis and the relative position relationship between the fan and the hard disk.

[0069] In the server provided in the present application, the fan, hard disk, and noise reduction structure can be arranged on the same side of the chassis at the same time, so that the noise reduction structure is at least partially located on the path where the noise generated by the fan is transmitted to the hard disk to attenuate the noise energy, while enabling the noise reduction structure to simultaneously reduce the airflow generated by the fan that is transmitted to the hard disk, thereby reducing the vibration of the hard disk caused by the airflow.

[0070] The second aspect of the present application provides a server, including a chassis and the above-mentioned noise reduction structure, wherein a hard disk and a fan are arranged at intervals in the chassis; the noise reduction structure is arranged in the chassis and is at least partially located on the path where the noise generated by the fan is transmitted to the hard disk. The noise reduction structure includes a mounting portion 1, a first blocking portion 2 and a second blocking portion 3; the first blocking portion 2 is arranged on the mounting portion 1; the second blocking portion 3 is arranged on the mounting portion 1 and is spaced from the first blocking portion 2, and the second blocking portion 3, the first blocking portion 2 and the mounting portion 1 form a noise reduction space 4; wherein the first blocking portion 2, the second blocking portion 3 and the noise reduction space 4 are used to attenuate noise energy. The noise reduction structure of the present application is installed in the chassis and is located on the path where the noise generated by the fan is transmitted to the hard disk. On the first hand, the sound waves of the noise will be partially reflected when contacting the first barrier part 2 and the second barrier part 3, thereby attenuating the energy; on the second hand, since the air in the noise reduction space 4 and the first barrier part 2 and the second barrier part 3 are different sound propagation media, the sound waves of the noise will be refracted when passing through the first barrier part 2, the noise reduction space 4 and the second barrier part 3 in sequence, thereby changing the original propagation direction of the sound wave, resulting in the growth of the sound wave propagation path to increase the attenuation of the sound wave energy; on the third hand, the sound waves of the noise will be reflected with the side walls of the space many times in the noise reduction space 4, causing energy attenuation, and at the same time, when the sound waves propagate in the noise reduction space 4, they will rub against the air in the space, thereby causing energy attenuation. In summary, through the application of the present application, the energy of the noise in the chassis of the server is effectively attenuated during the propagation process, the purpose of noise reduction is achieved, and the read and write speed of the hard disk in the chassis is guaranteed.
