Description

Technical Field

[0001] The present invention relates to the technical field of server noise reduction, and more specifically, to a server muffler and a server. Background Art

[0002] With the rapid development of electronic information technology, servers, as key infrastructure supporting modern data centers, are widely used in all walks of life. However, when servers process large amounts of data and perform complex computing tasks, the various electronic components in the server generate significant heat. If this heat cannot be discharged in time, it will affect the operation of the server. Therefore, effective heat dissipation is crucial to the stable operation of the server.

[0003] In the related art, fans are used to drive air flow, so as to use the flowing air to take away the heat emitted by the electronic components of the server. However, when the fan is running at high speed, it will generate noise with multiple frequency components, such as aerodynamic noise, electromagnetic noise and vibration noise, etc. These noises not only affect the working environment of the server, but also easily affect the precision parts inside the server, especially for the server hard disk. Since the server hard disk includes precision components such as magnetic heads, magnetic arms, bearings and motors, these precision components are small in size and extremely sensitive to external vibration and noise, and are easily affected by resonance to affect normal operation, thereby affecting the performance of the server hard disk. For example, the resonance inside the hard disk may cause the magnetic head to be unable to accurately position on the nanometer-level magnetic track, thereby causing the hard disk to have a decline in read and write performance, and even generate bad sectors, which ultimately leads to the early scrapping of the hard disk.

[0004] In order to solve this technical problem, in the related art, a muffler is installed on the server fan mounting bracket to reduce the noise of the airflow of the fan mounted on the fan mounting bracket. However, the muffler of this structure occupies a large space and has a great impact on the structure of the server.

[0005] Therefore, how to reduce the space occupied by the server muffler is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0014] On the other hand, both the first acoustic cavity and the second acoustic cavity are Helmholtz anechoic cavities.

[0015] On the other hand, the acoustic cavity comprises:

[0016] A third acoustic cavity is provided on a side of the plate-like member that is away from the hard disk backplane.

[0017] On the other hand, the plate-like member includes a first longitudinal beam extending along its width direction, the first longitudinal beam is provided with the first acoustic cavity on both sides along the length direction of the plate-like member, and the third acoustic cavity is provided in the middle part of the first longitudinal beam along the length direction.

[0018] On the other hand, the plate-like member includes a second longitudinal beam extending along its width direction, and the first acoustic cavity is provided on both sides of the second longitudinal beam along the length direction of the plate-like member.

[0019] On the other hand, the plate-like member includes a first side longitudinal beam extending along its width direction, the first side longitudinal beam is provided with the first acoustic cavity on one side along the length direction of the plate-like member, and the first side longitudinal beam is provided with the third acoustic cavity.

[0020] On the other hand, the plate-like member includes a first crossbeam extending along its length direction, the second avoidance hole is arranged on the first crossbeam, and the first crossbeam is provided with the third sound cavity.

[0021] On the other hand, the third acoustic cavity is a quarter-wavelength resonant cavity.

[0022] On the other hand, a side of the plate-like member facing away from the hard disk back plate is connected with sound-absorbing cotton.

[0023] On the other hand, the thickness of the sound-absorbing cotton ranges from 2 to 6 mm.

[0035] The server muffler is integrated with the hard disk backplane of the server to muffle and reduce the noise passing through the hard disk backplane. It is understandable that the hard disk backplane is located between the server hard disk and the fan in the server. Therefore, after the server muffler is integrated with the hard disk backplane, the server muffler is located on the path of the airflow driven by the fan, so that the sound cavity on the plate-shaped member of the server muffler can be used to muffle and reduce the noise of the airflow passing through the hard disk backplane, preventing the noise from reaching the server hard disk, causing the server hard disk to resonate, and affecting the performance of the server hard disk. That is, the server muffler can avoid the impact of noise on the performance of the server hard disk by muffler and reducing the noise at the hard disk backplane.

Compared with the related art in which the server silencer is integrated with the fan bracket for installing the fan (the server silencer integrated with the fan bracket is a cylindrical sound cavity structure, and the cylindrical sound cavity structure occupies a large space), the thickness of the plate-like member of the server silencer of the hard disk backplane is relatively small, and the space occupied is small; moreover, the overall shape of the plate-like member can be highly consistent with the overall shape of the hard disk backplane, which is more practical and has less impact on the structure of the server. Therefore, the server silencer provided by the embodiment of the present invention has good universality and expands the application scenarios of the server silencer, especially in 1U or 2U servers, the server silencer can be directly applied.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The core of the present invention is to provide a server muffler, which occupies a small space. Another core of the present invention is to provide a server including the above server muffler, wherein the server muffler occupies a small space.

[0050] It should be noted that, for ease of understanding, in the embodiment of the present invention, the length direction of the plate-like member 1 refers to the length direction of the plate-like member 1 in the drawings of the specification. Figures 2 to 5 The X-axis direction in the figure, the width direction (or height direction) of the plate-like member 1 refers to the Figures 2 to 5 The Z-axis direction in the figure, the thickness direction of the plate-like member 1 refers to the Z-axis direction in the figure of the specification. Figures 2 to 5 The Z-axis direction.

[0051] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a server muffler, including a plate-shaped member 1, the plate-shaped member 1 is used to communicate with a server 5 (such as Figure 6The hard disk backplane 4 (as shown) Figure 5 The plate-like member 1 is connected with a first avoidance hole 11 and a second avoidance hole 12 which respectively penetrate through the wall thickness thereof. The first avoidance hole 11 is used to avoid the connector 41 (as shown in FIG. Figure 5 As shown), the second avoidance hole 12 is used to avoid the heat dissipation duct of the hard disk backplane 4; the plate-like member 1 is also provided with a sound cavity 13, and the sound cavity 13 is used for noise reduction.

[0052] That is to say, the embodiment of the present invention integrates the server muffler with the hard disk backplane 4 of the server 5 to muffle and reduce the noise passing through the hard disk backplane 4. It can be understood that the hard disk backplane 4 is located between the server hard disk and the fan in the server 5. Therefore, after the server muffler is integrated with the hard disk backplane 4, the server muffler is located on the path of the airflow driven by the fan, so that the sound cavity 13 on the plate-shaped member 1 of the server muffler can be used to muffle and reduce the noise of the airflow passing through the hard disk backplane 4, preventing the noise from reaching the server hard disk, causing the server hard disk to resonate, and affecting the performance of the server hard disk. That is, the server muffler can avoid the influence of noise on the performance of the server hard disk by muffler and reducing the noise at the hard disk backplane 4.

[0053] Moreover, the embodiment of the present invention integrates the server silencer with the hard disk backplane 4. Compared with the related art in which the server silencer is integrated with the fan bracket for installing the fan (the server silencer integrated with the fan bracket is a cylindrical sound cavity structure, and the cylindrical sound cavity structure occupies a large space), the thickness of the plate-like member 1 of the server silencer of the hard disk backplane 4 is relatively small, and the space occupied is small; moreover, the overall shape of the plate-like member 1 can be highly coincident with the overall shape of the hard disk backplane 4, and the degree of practicality is higher, and the impact on the structure of the existing server is smaller. Therefore, the server silencer provided by the embodiment of the present invention has good universality and expands the application scenarios of the server silencer, especially in 1U or 2U servers, the server silencer can be directly applied.

[0054] It can be understood that the first avoidance hole 11 is used to avoid the connector 41 of the hard disk backplane 4, so that the connector 41 of the hard disk backplane 4 can pass through the first avoidance hole 11, avoiding the interference between the connector 41 of the hard disk backplane 4 and the plate-like member 1, which affects the integration of the plate-like member 1 and the hard disk backplane 4. It should be noted that the position of the first avoidance hole 11 is determined by the position of the connector 41 of the hard disk backplane 4, and the number of the first avoidance holes 11 can be determined according to the number of connectors 41 of the hard disk backplane 4 and the distribution of the connectors 41. It can be that one first avoidance hole 11 corresponds to one connector 41, or two or more relatively concentrated connectors 41 correspond to the same first avoidance hole 11 that can completely cover multiple connectors 41. In addition, this embodiment does not limit the specific shape of the first avoidance hole 11. The shape of the first avoidance hole 11 can be any shape, as long as the size of the first avoidance hole 11 can smoothly avoid the corresponding connector 41. In some embodiments, the shape of the first avoidance hole 11 is a rectangular hole or a rectangular groove. It should be noted that the first avoidance hole 11 can be a closed structure or a non-closed structure, that is, at least one side wall of the first avoidance hole 11 can have an opening, as long as the connector 41 of the hard disk backplane 4 can pass through the opening. For example, in some embodiments, the first avoidance hole 11 includes a closed hole that is closed on all sides and a non-closed hole that is not closed on one side. Furthermore, in some embodiments, the non-closed hole is provided in the plate-like member 1 along its width direction (or height direction, such as Figure 2 The bottom of the plate-like member 1 (in the Z-axis direction) has a structure that facilitates the passage of a connector 41 or a cable, etc., from the bottom of the plate-like member 1 along its width direction.

[0055] Furthermore, in some embodiments, the first avoidance hole 11 is also used to provide the operating space required for operating the connector 41 of the hard disk backplane 4, that is, the size of the first avoidance hole 11 can also meet the needs of operating the connector 41 of the hard disk backplane 4.

[0056] In addition, the second avoidance hole 12 is used to avoid the heat dissipation air duct of the hard disk back plate 4, so as to prevent the physical structure of the plate-shaped member 1 from blocking the heat dissipation air duct of the hard disk back plate 4 and affecting the passage of the heat dissipation airflow. It can be understood that the position and number of the second avoidance holes 12 are determined by the position and number of the heat dissipation air duct of the hard disk back plate 4, and the shape of the second avoidance hole 12 can be any shape, as long as the size of the second avoidance hole 12 can smoothly avoid the heat dissipation air duct of the hard disk back plate 4. In some embodiments, the shape of the second avoidance hole 12 is a long strip hole.

[0057] In addition, the present embodiment does not limit the specific structure of the acoustic cavity 13, as long as the acoustic cavity 13 has the function of sound absorption and noise reduction.

[0058] Please continue to refer to Figure 1 and Figure 2In some embodiments, the sound cavity 13 includes a first sound cavity 131 , which is disposed at a portion of the inner wall of the plate-like member 1 corresponding to the first avoidance hole 11 , and the first sound cavity 131 is connected to the first avoidance hole 11 .

[0059] It can be understood that the size of the first avoidance hole 11 is relatively large. When working, the airflow driven by the fan will pass through the first avoidance hole 11 when passing through the plate-like member 1. Therefore, in order to improve the sound absorption and noise reduction effect, this embodiment arranges the first sound cavity 131 at the position of the inner wall of the plate-like member 1 corresponding to the first avoidance hole 11, and makes the first sound cavity 131 connected with the first avoidance hole 11. In this way, when the airflow passes through the first avoidance hole 11, it can enter the first sound cavity 131, and the first sound cavity 131 is used to absorb and reduce noise.

[0060] It should be noted that the present embodiment does not limit the specific shape of the first acoustic cavity 131 . In some embodiments, the first acoustic cavity 131 is a Helmholtz anechoic cavity.

[0061] In addition, the present embodiment does not limit the specific number of the first sound cavities 131. The number of the first sound cavities 131 corresponding to the single-side hole wall of the first avoidance hole 11 may be one or at least two. When the number of the first sound cavities 131 corresponding to the single-side hole wall of the first avoidance hole 11 is at least two, the first sound cavities 131 may be arranged in at least one row on the single-side hole wall of the first avoidance hole 11.

[0062] In addition, the present embodiment does not limit the specific number of openings connecting the first acoustic cavity 131 and the first avoidance hole 11. The number of openings connecting a single first acoustic cavity 131 and the first avoidance hole 11 may be one or at least two.

[0063] In addition, the present embodiment does not limit the position of the first sound cavity 131 corresponding to the hole wall of the first avoidance hole 11 . For example, the first sound cavity 131 may be provided on any side hole wall of the first avoidance hole 11 .

[0064] Furthermore, considering the limitation of structural size, in some embodiments, the first avoidance hole 11 includes a first hole wall and a second hole wall relatively arranged along the length direction of the plate-like member 1, and a first sound cavity 131 is provided at the positions of the plate-like member 1 corresponding to the first hole wall and the second hole wall respectively.

[0065] That is to say, in this embodiment, the first sound cavity 131 is preferentially set at the position of the hole wall (that is, the first hole wall and the second hole wall) of the plate-like member 1 corresponding to the first avoidance hole 11 along the length direction of the plate-like member 1. It can be understood that the planes where the first hole wall and the second hole wall are located are respectively perpendicular to the length direction of the plate-like member 1.

[0066] In addition, it can be understood that the dimension of the plate-like member 1 in the length direction is relatively long, so when the first avoidance hole 11 and the second avoidance hole 12 are provided, the physical structure dimension between two adjacent first avoidance holes 11 along the length direction of the plate-like member 1 can be relatively large, so as to facilitate the provision of the sound cavity 13. The dimension of the plate-like member 1 in the width direction is relatively short, so when the first avoidance hole 11 and the second avoidance hole 12 are provided, the physical structure dimension of the plate-like member 1 in the width direction is relatively small, which is not conducive to the provision of the sound cavity 13.

[0067] For further information, please refer to Figure 1 and Figure 2 In order to improve the effect of sound absorption and noise reduction, in some embodiments, the first avoidance hole 11 also includes a third hole wall extending along the length direction of the plate-like member 1, and a protruding structure 14 is provided at a position of the plate-like member 1 corresponding to the third hole wall. The protruding structure 14 protrudes from the inner side surface of the third hole wall and the outer side surface corresponding to the third hole wall along the width direction of the plate-like member 1. The protruding structure 14 is provided with a second sound cavity 132, and the second sound cavity 132 is connected to the first avoidance hole 11.

[0068] That is to say, in this embodiment, at the position where the structural space of the plate-like member 1 corresponding to the third hole wall is insufficient, a protruding structure 14 is provided, and a mutation structure is formed by using the protruding structure 14, so as to achieve the purpose of providing the second sound cavity 132 at the protruding structure 14. The second sound cavity 132 cooperates with the first sound cavity 131, and the two work together to ensure the integrity of the sound cavity 13 structure on the noise transmission path, which is conducive to eliminating the target frequency noise passing through the first avoidance hole 11. In other words, when the airflow passes through the first avoidance hole 11, the noise can enter the first sound cavity 131 and the second sound cavity 132, and the first sound cavity 131 and the second sound cavity 132 are used to jointly mute and reduce the noise.

[0069] It should be noted that the present embodiment does not limit the specific shape of the second acoustic cavity 132 . In some embodiments, the second acoustic cavity 132 is a Helmholtz anechoic cavity.

[0070] In addition, the present embodiment does not limit the specific number of the second acoustic cavities 132, and the protruding structure 14 may be provided with one second acoustic cavity 132, or at least two second acoustic cavities 132. In addition, the present embodiment does not limit the specific number of the protruding structures 14, and the number of the protruding structures 14 may be one, or at least two.

[0071] In addition, the present embodiment does not limit the specific number of openings connecting the second acoustic cavity 132 and the first avoidance hole 11. The number of openings connecting a single second acoustic cavity 132 and the first avoidance hole 11 may be one or at least two.

[0072] In some embodiments, the protruding structure 14 is disposed at a position on the top of the plate-like member 1 corresponding to a third hole wall of the first avoidance hole 11 close to the top edge of the plate-like member 1 .

[0073] In addition, please continue to refer to Figure 1 and Figure 2 In some embodiments, the acoustic cavity 13 includes a third acoustic cavity 133 , and the third acoustic cavity 133 is disposed on a side of the plate-like member 1 that is away from the hard disk back plate 4 .

[0074] That is to say, in this embodiment, the third sound cavity 133 is arranged on a plane perpendicular to the thickness direction of the plate-like member 1, and the opening of the third sound cavity 133 is toward the side of the plate-like member 1 away from the back plate, so that the third sound cavity 133 can eliminate the noise reaching the hard disk back plate 4. It can be understood that the third sound cavity 133 plays a complementary role in noise reduction of the first sound cavity 131, so that the noise reduction effect is better. In addition, it can be understood that the third sound cavity 133 can also achieve weight reduction of the overall structure of the plate-like member 1.

[0075] It should be noted that this embodiment does not limit the shape of the third acoustic cavity 133. In some embodiments, the third acoustic cavity 133 is a quarter-wavelength resonant cavity.

[0076] Furthermore, in some embodiments, the acoustic cavity 13 includes a first acoustic cavity 131 and a third acoustic cavity 133, wherein the first acoustic cavity 131 is a Helmholtz anechoic cavity, and the third acoustic cavity 133 is a quarter-wavelength resonant cavity. In other words, this embodiment makes full use of the space in the thickness direction of the plate-like member 1, and adopts the combination of the Helmholtz anechoic cavity and the quarter-wavelength resonant cavity to achieve high-efficiency anechoic noise reduction.

[0077] In addition, the present embodiment does not limit the specific number of the third acoustic cavities 133 , and the number of the third acoustic cavities 133 may be one or at least two.

[0078] In addition, the present embodiment does not limit the specific location of the third acoustic cavity 133 , as long as the side of the plate-like member 1 away from the back plate has sufficient physical structure to set the third acoustic cavity 133 .

[0079] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the plate-like member 1 includes a first longitudinal beam 15 extending along its width direction, a first acoustic cavity 131 is provided on both sides of the first longitudinal beam 15 along the length direction of the plate-like member 1, and a third acoustic cavity 133 is provided in the middle part of the first longitudinal beam 15 along the length direction of the plate-like member 1.

[0080] That is to say, in this embodiment, the first longitudinal beam 15 has a sufficient width along the length direction of the plate-like member 1, so that the first longitudinal beam 15 has a sufficient volume, so that the first sound cavity 131 is respectively set on both sides of the first longitudinal beam 15 along the length direction of the plate-like member 1, and the third sound cavity 133 is set in the middle part of the first longitudinal beam 15 along the length direction of the plate-like member 1, so as to realize the integration of the first sound cavity 131 and the third sound cavity 133 on the first longitudinal beam 15, so that the sound cavity 13 at the first longitudinal beam 15 is denser, thereby having a better sound reduction effect. It can be understood that the overall size of the first longitudinal beam 15 can meet the setting of the first sound cavity 131 and the third sound cavity 133, so that the first sound cavity 131 and the third sound cavity 133 do not interfere with each other.

[0081] It should be noted that the present embodiment does not limit the specific distribution of the third acoustic cavity 133. In some embodiments, the number of the third acoustic cavity 133 is at least two, and all the third acoustic cavities 133 are distributed in at least one row along the length direction of the plate-like member 1 on the first longitudinal beam 15, and in at least one column along the width direction of the plate-like member 1.

[0082] In addition, please continue to refer to Figure 1 and Figure 2 In some embodiments, the plate-like member 1 includes a second longitudinal beam 16 extending along its width direction, and the second longitudinal beam 16 is provided with a first acoustic cavity 131 on both sides along the length direction of the plate-like member 1.

[0083] That is to say, in the present embodiment, the width dimension of the second longitudinal beam 16 along the length direction of the plate-like member 1 can satisfy the requirement of respectively setting the first acoustic cavity 131 on both sides of the second longitudinal beam 16 along the length direction of the plate-like member 1. That is, compared with the first longitudinal beam 15, the second longitudinal beam 16 is not provided with the third acoustic cavity 133. This can make the width dimension of the second longitudinal beam 16 along the length direction of the plate-like member 1 smaller than the width dimension of the first longitudinal beam 15 along the length direction of the plate-like member 1, which is conducive to meeting the dimensional requirements of the plate-like member 1 along its length direction as much as possible while satisfying the need to set the first acoustic cavity 131.

[0084] In order to achieve a better overall heat dissipation effect for the hard disk backplane 4, in some embodiments, the first longitudinal beam 15 and the second longitudinal beam 16 are alternately arranged along the length direction of the plate-like member 1, that is, a second longitudinal beam 16 is provided between any two adjacent first longitudinal beams 15, or a first longitudinal beam 15 is provided between any two adjacent second longitudinal beams 16.

[0085] In some embodiments, the plate-like member 1 includes two first longitudinal beams 15 and one second longitudinal beam 16, one second longitudinal beam 16 is located between the two first longitudinal beams 15, and the two first longitudinal beams 15 are respectively provided with a first side longitudinal beam 171 on one side away from the second longitudinal beam 16, and the first side longitudinal beam 171 is located at the edge of the plate-like member 1. It can be understood that the first avoidance hole 11 and / or the second wall hole are provided between the first side longitudinal beam 171 and the first longitudinal beam 15 and between the first longitudinal beam 15 and the second longitudinal beam 16.

[0086] In addition, please continue to refer to Figure 1 and Figure 2 In some embodiments, the plate-like member 1 includes a first side longitudinal beam 171 extending along its width direction, and the first side longitudinal beam 171 is provided with a first acoustic cavity 131 on one side along the length direction of the plate-like member 1, and the first side longitudinal beam 171 is provided with a third acoustic cavity 133.

[0087] That is to say, in the present embodiment, a first acoustic cavity 131 is provided on one side of the first side longitudinal beam 171 along the length direction of the plate-like member 1, and the outer side of the first side longitudinal beam 171 along the length direction of the plate-like member 1 serves as the edge portion of the plate-like member 1 and is not provided with the first acoustic cavity 131. At the same time, a third acoustic cavity 133 is provided on the side of the first side longitudinal beam 171 away from the hard disk backplane 4. It can be understood that the third acoustic cavity 133 on the first side longitudinal beam 171 is close to the outer side of the first side longitudinal beam 171 along the length direction of the plate-like member 1 to avoid interference with the first acoustic cavity 131 on the first side longitudinal beam 171.

[0088] In addition, it can be understood that the width dimension of the first side longitudinal beam 171 along the length direction of the plate-like member 1 can satisfy the requirement of setting the first sound cavity 131 on one side of the first side longitudinal beam 171 along the length direction of the plate-like member 1, and setting the third sound cavity 133 on the first side longitudinal beam 171. That is, compared with the first longitudinal beam 15 and the second longitudinal beam 16, the first side longitudinal beam 171 is a structure in which the first sound cavity 131 is set on one side, and the third sound cavity 133 is set, which can ensure the sound-absorbing and noise-reducing effect at the position close to the edge of the plate-like member 1 along its length direction.

[0089] In addition, please continue to refer to Figure 1 and Figure 2 In some embodiments, the plate-like member 1 includes a second side longitudinal beam 172 extending along its width direction, the first side longitudinal beam 171 and the second side longitudinal beam 172 are respectively located at the two ends of the plate-like member 1 along its length direction, serving as two edge portions of the plate-like member 1 along its length direction, and the second side longitudinal beam 172 is provided with a first acoustic cavity 131 on one side along the length direction of the plate-like member 1, and at the same time, the second side longitudinal beam 172 is provided with a long strip of heat dissipation ventilation holes 1721 extending along its length direction.

[0090] In addition, please continue to refer to Figure 1 and Figure 2In some embodiments, the plate-like member 1 includes a first beam 181 extending along its length direction, the second avoidance hole 12 is provided on the first beam 181 , and the first beam 181 is provided with a third sound cavity 133 .

[0091] That is to say, in this embodiment, by setting the first cross beam 181, a second wall hole is set on the first cross beam 181, so that the second wall hole extends along the length direction of the first cross beam 181, that is, the second avoidance hole 12 extends along the length direction of the plate-like member 1; at the same time, a third sound cavity 133 is set on the first cross beam 181 to increase the number of the third sound cavity 133 and its distribution area, thereby improving the sound absorption and noise reduction effect.

[0092] It should be noted that, considering the specific distribution of the second avoidance holes 12, in some embodiments, a first beam 181 may be provided with one second avoidance hole 12, or may be provided with at least two second avoidance holes 12, and the second avoidance hole 12 may be provided in the center portion of the first beam 181, or may be provided at the edge portion of the first beam 181.

[0093] In addition, considering the specific distribution of the third acoustic cavity 133 , in some embodiments, the third acoustic cavity 133 on the first cross beam 181 is located close to the first longitudinal beam 15 , the second longitudinal beam 16 , the first side longitudinal beam 171 or the second side longitudinal beam 172 .

[0094] It is understandable that the first crossbeam 181 is located between the first side longitudinal beam 171 (or the second side longitudinal beam 172) and the first longitudinal beam 15, or between the first longitudinal beam 15 and the second longitudinal beam 16, or between the second longitudinal beam 16 and the first side longitudinal beam 171 (or the second side longitudinal beam 172). The first crossbeam 181 plays a bridge role connecting the first side longitudinal beam 171 (or the second side longitudinal beam 172) and the first longitudinal beam 15, or the first longitudinal beam 15 and the second longitudinal beam 16, or the second longitudinal beam 16 and the first side longitudinal beam 171 (or the second side longitudinal beam 172). It should be noted that the lengths of the first crossbeam 181 between the first side longitudinal beam 171 (or the second side longitudinal beam 172) and the first longitudinal beam 15, the first crossbeam 181 between the first longitudinal beam 15 and the second longitudinal beam 16, and the first side longitudinal beam 171 (or the second side longitudinal beam 172) and the second longitudinal beam 16 may be equal or unequal.

[0095] In addition, the first transverse beam 181 , the first side longitudinal beam 171 , the first longitudinal beam 15 , the second longitudinal beam 16 and the second side longitudinal beam 172 are also used to form the first avoidance hole 11 together.

[0096] For example, in some embodiments, a first avoidance hole 11 is provided between any two adjacent first cross beams 181 , and a first avoidance hole 11 is provided between any adjacent first side longitudinal beams 171 and first longitudinal beams 15 , between adjacent first longitudinal beams 15 and second longitudinal beams 16 , and between adjacent first longitudinal beams 15 and second side longitudinal beams 172 .

[0097] Considering the specific distribution of the first avoidance holes 11, in some embodiments, the first avoidance holes 11 are arranged at intervals along the length direction of the plate-like member 1, and the first avoidance holes 11 are arranged at intervals along the width direction of the plate-like member 1, so that the first avoidance holes 11 are arranged in at least one row in the length direction of the plate-like member 1, and are arranged in at least one column in the width direction of the plate-like member 1. It should be noted that the first avoidance holes 11 located in the same row along the length direction of the plate-like member 1 are aligned along the width direction of the plate-like member 1, and the first avoidance holes 11 located in the same column along the width direction of the plate-like member 1 are aligned along the length direction of the plate-like member 1. In addition, it can be understood that along the length direction of the plate-like member 1, between any two adjacent first avoidance holes 11 is the first longitudinal beam 15 or the second longitudinal beam 16; along the width direction of the plate-like member 1, between any two adjacent first avoidance holes 11 is the first cross beam 181.

[0098] In addition, in some embodiments, the plate-like member 1 further includes a second crossbeam 182 extending along its length direction, and the second crossbeam 182 is located at the edge of the plate-like member 1 along its width direction. In some embodiments, the second crossbeam 182 serves as a third hole wall of the first avoidance hole 11 near the edge of the plate-like member 1.

[0099] In some embodiments, the second cross beam 182 is provided with the protruding structure 14 described above, that is, the second cross beam 182 is provided with the second acoustic cavity 132 .

[0100] In some embodiments, the second cross beam 182 is disposed on the top of the plate-like member 1 .

[0101] In some embodiments, a first avoidance hole 11 is formed between a portion of the first side longitudinal beam 171, the first cross beam 181, the second cross beam 182 and a portion of the first longitudinal beam 15; a first avoidance hole 11 is formed between a portion of the first side longitudinal beam 171, the two first cross beams 181 and a portion of the first longitudinal beam 15; a first avoidance hole 11 is formed between a portion of the first longitudinal beam 15, the first cross beam 181, the second cross beam 182 and a portion of the second longitudinal beam 16; a first avoidance hole 11 is formed between a portion of the first longitudinal beam 15, the two first cross beams 181 and a portion of the second longitudinal beam 16; a first avoidance hole 11 is formed between a portion of the first longitudinal beam 15, the first cross beam 181, the second cross beam 182 and a portion of the second side longitudinal beam 172; a first avoidance hole 11 is formed between a portion of the first longitudinal beam 15, the two first cross beams 181 and a portion of the second side longitudinal beam 172.

[0102] It should be noted that the embodiment of the present invention does not limit the specific thickness of the plate-like member 1 , as long as it can meet the setting requirements of the sound cavity 13 .

[0103] In addition, in order to reduce the overall weight of the server muffler, in some embodiments, the plate-like member 1 is provided with weight-reducing holes to reduce the overall weight of the plate-like member 1 .

[0104] It should be noted that the present embodiment does not limit the specific number and location of the weight-reducing holes. In some embodiments, the weight-reducing holes are disposed on the first longitudinal beam 15 , the second longitudinal beam 16 , the first side longitudinal beam 171 and / or the second side longitudinal beam 172 .

[0105] In addition, the present embodiment does not limit the specific shape of the weight-reducing hole, and the weight-reducing hole may be a circular hole, an elliptical hole, an oblong hole, an L-shaped hole, or a hole of other shapes.

[0106] Also, please refer to Figure 3 In order to improve the sound-absorbing and noise-reducing effect, in some embodiments, a side of the plate-like member 1 facing away from the hard disk back plate 4 is connected with a sound-absorbing cotton 2 .

[0107] That is to say, in this embodiment, in addition to providing the sound cavity 13, the plate-like member 1 also combines with the sound-absorbing cotton 2 to achieve the purpose of comprehensive sound absorption and noise reduction, which is conducive to achieving overall optimization of narrow-band high-amplitude noise and broadband noise.

[0108] It should be noted that this embodiment does not limit the specific thickness of the sound-absorbing cotton 2.

[0109] In some embodiments, the thickness of the sound-absorbing cotton 2 is in the range of 2 mm to 6 mm. It should be noted that the inventor of the present application has found that when the thickness of the sound-absorbing cotton 2 is in the range of 2 mm to 6 mm, the comprehensive sound-absorbing and noise-reducing effect of the sound-absorbing cotton 2 and the plate-shaped member 1 is better. If the thickness of the sound-absorbing cotton 2 is too small, the sound-absorbing effect of the sound-absorbing cotton 2 is not obvious, and the better cooperation effect cannot be achieved; when the thickness of the sound-absorbing cotton 2 is too large, the sound-absorbing and noise-reducing effect of the sound cavity 13 of the plate-shaped member 1 will be weakened.

[0110] Furthermore, in some embodiments, the thickness of the sound-absorbing cotton 2 is 4 mm.

[0111] In addition, the present embodiment does not limit the specific connection method between the sound-absorbing cotton 2 and the plate-like member 1, as long as the connection between the sound-absorbing cotton 2 and the plate-like member 1 can be achieved. In some embodiments, the sound-absorbing cotton 2 and the plate-like member 1 are bonded by an adhesive, or connected by a fastener, or connected by a clamp, or other fixed structures to achieve a fixed connection between the sound-absorbing cotton 2 and the plate-like member 1, as long as the sound-absorbing cotton 2 and the plate-like member 1 can be connected together.

[0112] In some embodiments, the sound-absorbing cotton 2 is adhered to a surface of the plate-like member 1 on one side away from the hard disk back plate 4 .

[0113] In addition, this embodiment does not specifically limit the shape and size of the sound-absorbing cotton 2. In some embodiments, the contour shape of the sound-absorbing cotton 2 is the same as the contour shape of the plate-like member 1, and the dimensions of the sound-absorbing cotton 2 along the length direction and the width direction are respectively the same as the dimensions of the plate-like member 1 in the length direction and the width direction.

[0114] For further information, please refer to Figure 3 In some embodiments, the sound-absorbing cotton 2 is provided with a third avoidance hole 21 and a fourth avoidance hole 22 , the third avoidance hole 21 corresponds to the first avoidance hole 11 ; the fourth avoidance hole 22 corresponds to the second avoidance hole 12 .

[0115] That is to say, in this embodiment, the third avoidance hole 21 is provided on the sound-absorbing cotton 2 to avoid the first avoidance hole 11 on the plate-shaped member 1, so as to avoid the sound-absorbing cotton 2 blocking the first avoidance hole 11 and affecting the sound-absorbing and noise-reducing effect of the first sound cavity 131 and the second sound cavity 132. In addition, the fourth avoidance hole 22 is provided on the sound-absorbing cotton 2 to avoid the second avoidance hole 12 on the plate-shaped member 1, so as to avoid the sound-absorbing cotton 2 blocking the second avoidance hole 12, so that the heat dissipation duct on the hard disk backplane 4 can be exposed to facilitate the passage of heat dissipation airflow.

[0116] It can be understood that the position and number of the third avoidance hole 21 are determined by the position and number of the first avoidance hole 11 on the plate-like member 1, and the shape of the third avoidance hole 21 can be any shape, as long as the size of the third avoidance hole 21 can smoothly avoid the first avoidance hole 11. In some embodiments, the shape of the third avoidance hole 21 is the same as the shape of the first avoidance hole 11, and the size of the third avoidance hole 21 is equal to the size of the first avoidance hole 11. Correspondingly, the third avoidance hole 21 can be a closed structure or a non-closed structure, that is, at least one side wall of the third avoidance hole 21 can have an opening. For example, in some embodiments, the third avoidance hole 21 includes a closed hole that is closed on all sides and a non-closed hole that is not closed on one side. Further, in some embodiments, the non-closed hole is provided at the bottom of the sound-absorbing cotton 2 along its width direction (or height direction).

[0117] In addition, it can be understood that the position and number of the fourth avoidance hole 22 are determined by the position and number of the second avoidance hole 12, and the shape of the fourth avoidance hole 22 can be any shape, as long as the size of the fourth avoidance hole 22 can smoothly avoid the position of the second avoidance hole 12. In some embodiments, the shape of the fourth avoidance hole 22 is the same as the shape of the second avoidance hole 12, and the size of the fourth avoidance hole 22 is equal to the size of the second avoidance hole 12.

[0118] In addition, please continue to refer to Figure 3 It can be understood that a fifth avoidance hole 23 is provided at the position of the third sound cavity 133 of the plate-shaped member 1 corresponding to the sound-absorbing cotton 2, so that the third sound cavity 133 is exposed to the outside by utilizing the fifth avoidance hole 23, thereby preventing the sound-absorbing cotton 2 from blocking the third sound cavity 133 and affecting the sound-absorbing and noise-reducing effect of the third sound cavity 133.

[0119] Also, please refer to Figure 4 and Figure 5 In order to facilitate the integration of the plate-like member 1 and the hard disk backplane 4 , in some embodiments, the plate-like member 1 is connected with a mounting bracket 3 , and the mounting bracket 3 is used to mount the hard disk backplane 4 .

[0120] That is to say, the server muffler in this embodiment is installed on the mounting bracket 3 through the plate-like member 1, and the mounting bracket 3 is also used to install the hard disk backplane 4, and the server muffler and the hard disk backplane 4 are integrated through the mounting bracket 3. In other words, in this embodiment, the plate-like member 1 can be installed on the existing mounting bracket of the hard disk backplane 4. It should be noted that when the plate-like member 1 is installed on the existing mounting bracket of the hard disk backplane 4, it is necessary to make adaptive structural improvements to the mounting bracket of the hard disk backplane 4, so as to provide a maximized structural space for the server muffler and adapt the installation of the plate-like member 1 on the mounting bracket of the hard disk backplane 4.

[0121] It should be noted that the present embodiment does not limit the specific structure of the mounting bracket 3, as long as the mounting bracket 3 has sufficient structural strength and rigidity, and can simultaneously realize the installation of the hard disk backplane 4 and the plate-like member 1. It is understandable that the mounting bracket 3 is reserved with a large number of ventilation holes to ensure the normal heat dissipation of the server hard disk. In addition, it is understandable that the mounting bracket 3 is usually a metal structural member to ensure that the mounting bracket 3 has sufficient structural strength and rigidity to provide sufficient structural support for the plate-like member 1 and the hard disk backplane 4, which is conducive to ensuring the overall structural strength and rigidity of the server muffler and the hard disk backplane 4, and ensuring that the server muffler and the hard disk backplane 4 maintain the correct position and work reliability. Of course, in other embodiments, the mounting bracket 3 can also be other materials, as long as the mounting bracket 3 can meet the installation of the hard disk backplane 4 and the plate-like member 1.

[0122] Furthermore, in order to improve the stability of the installation of the plate-like member 1, as Figure 4 As shown, in some embodiments, the mounting bracket 3 is provided with a mounting surface 31 , and one surface of the plate-like member 1 along its thickness direction is in contact with the mounting surface 31 .

[0123] That is to say, when the plate-like member 1 is installed on the mounting bracket 3, one side of the plate-like member 1 along its thickness direction (that is, the side of the plate-like member 1 facing the hard disk backplane 4) is in contact with the mounting surface 31 of the mounting bracket 3, and the mounting surface 31 has a certain flatness, which is conducive to ensuring the correctness of the position of the plate-like member 1 and the stability of the positioning.

[0124] It should be noted that the mounting surface 31 in this embodiment can be an integral local area surface, or a combination of at least two local area surfaces, that is, an integral local area surface can be reserved on the mounting bracket 3 to fit and limit the plate-like member 1; or at least two local area surfaces can be reserved on the mounting bracket 3, and the plate-like member 1 is in fit and contact with more than two local area surfaces at the same time to achieve limited installation of the plate-like member 1.

[0125] In addition, it should be noted that when the plate-like member 1 is installed on the existing mounting bracket 3 of the hard disk backplane 4, it is necessary to ensure that the rigidity and strength of the mounting bracket 3 change little, and eliminate some unnecessary local reinforcement structures (for example, the local bending reinforcement structure of the mounting bracket of the hard disk backplane 4 in the related art and the reinforcement sheet metal at the top of the mounting bracket are eliminated), so that the mounting bracket 3 of the hard disk backplane 4 has a mounting surface 31 for mounting the plate-like member 1. In this way, the installation of the plate-like member 1 can be realized on the basis of retaining the main structural features for mounting the hard disk backplane 4. This method not only retains the advantages of better rigidity and strength of the mounting bracket 3 (such as metal sheet metal parts) and the advantages of easier design and production of complex structural features, but also simplifies the design structure of the server muffler, providing sufficient space for the installation design of the server muffler.

[0126] For further information, please refer to Figure 4 In some embodiments, a surrounding frame 32 is provided at the edge of the mounting bracket 3 , and the plate-like member 1 is disposed in a space enclosed by the surrounding frame 32 .

[0127] That is to say, in this embodiment, the frame 32 at the edge of the mounting bracket 3 is used to enclose an installation space to accommodate the plate-like member 1. During installation, the plate-like member 1 is embedded in the space enclosed by the frame 32, which is beneficial to prevent the edge of the plate-like member 1 from being exposed, thereby providing a certain protective effect on the plate-like member 1. At the same time, the frame 32 is used to circumferentially limit the edge of the plate-like member 1, which is beneficial to quickly install and position the plate-like member 1, and to improve the stability of the plate-like member 1 fixed on the mounting bracket 3.

[0128] It should be noted that this embodiment does not limit the specific formation method of the frame 32, as long as the frame 32 can enclose a space for installing the plate-shaped member 1. The frame 32 can be formed by a bending process, or installed on the body of the mounting bracket 3 by welding or other processes.

[0129] In addition, it should be noted that the above embodiment does not limit the specific fixing method of the plate-like member 1 and the mounting bracket 3, as long as the fixing of the plate-like member 1 and the mounting bracket 3 can be achieved.

[0130] Please refer to Figure 1 and Figure 2 In some embodiments, a clearance groove 191 and a fixing portion 192 located at one end of the clearance groove 191 are provided at the edge of the plate-like member 1 , and the fixing portion 192 is provided with a mounting hole 193 , and the mounting hole 193 is connected to a fastener for fixing the plate-like member 1 .

[0131] That is, in this embodiment, by providing a clearance groove 191 along the thickness direction of the plate-like member 1, the portion of the plate-like member 1 corresponding to the clearance groove 191 forms a fixing portion 192, and the fixing portion 192 is provided with a mounting hole 193. When the plate-like member 1 is fixed to the mounting bracket 3, the fastener is connected to the mounting bracket 3 by passing the fastener through the mounting hole 193, thereby achieving the fixing of the plate-like member 1 to the mounting bracket 3. It can be understood that the clearance groove 191 plays a role in making way for the fastener to be installed. In some embodiments, the fastener includes a circular head, and the clearance groove 191 is a semicircular arc surface to facilitate the circular head of the fastener to pass through.

[0132] In addition, in some embodiments, the fastener includes a head pressed on a side of the fixing portion 192 away from the mounting bracket 3 , and when the fastener is fixed to the mounting bracket 3 , the head of the fastener is used to press the fixing portion 192 .

[0133] It can be understood that, in some embodiments, the clearance groove 191, the fixing portion 192 and the mounting hole 193 correspond one to one, that is, a clearance groove 191, a fixing portion 192 and a mounting hole 193 form a mounting portion, and the plate-like member 1 can be provided with at least one mounting portion. When there are at least two mounting portions, all the mounting portions are relatively evenly distributed in various areas of the plate-like member 1.

[0134] In some embodiments, the mounting parts are provided at two edge parts of the plate-like member 1 along its width direction. For the purpose of edge description, the two edge parts of the plate-like member 1 along its width direction are respectively referred to as first width edge parts and second width edge parts, and the mounting parts provided at the first width edge parts and the mounting parts provided at the second width edge parts correspond to each other. In some embodiments, the plate-like member 1 has four mounting parts at each of its two edge parts along its width direction.

[0135] In some embodiments, a first side longitudinal beam 171 is provided with a mounting portion at both ends along the width direction of the plate-like member 1; a first longitudinal beam 15 is provided with a mounting portion at both ends along the width direction of the plate-like member 1; a second longitudinal beam 16 is provided with a mounting portion at both ends along the width direction of the plate-like member 1; and a second side longitudinal beam 172 is provided with a mounting portion at both ends along the width direction of the plate-like member 1.

[0136] In addition, in addition to the solution of installing the server muffler on the mounting bracket 3 , in some other embodiments, there may also be such a solution: the plate-like member 1 is provided with a mounting position, and the mounting position is used to install the hard disk backplane 4 .

[0137] That is to say, in this embodiment, the plate-like member 1 is directly integrated with the hard disk backplane 4. During installation, the hard disk backplane 4 can be directly installed on the installation position of the plate-like member 1, so that the plate-like member 1 can be used as a server silencer to have the function of silencing and reducing noise. At the same time, the plate-like member 1 can also be used as a bracket of the hard disk backplane 4 to fix and support the hard disk backplane 4. That is, in this embodiment, the hard disk backplane 4 is designed onto the plate-like member 1, so that the bracket of the hard disk backplane 4 is integrated with the silencing and noise reduction function, thereby expanding the function of the server silencer and facilitating the formation of a high-density and low-noise server. This solution is equivalent to eliminating the bracket used to install the hard disk backplane 4 in the related technology, thereby reducing structural parts and saving costs. It can be understood that when adopting this solution, it is necessary to ensure that the plate-like member 1 itself has sufficient rigidity and strength, and at the same time, it is necessary to ensure the sound absorption performance of the plate-like member 1. In addition, it should be noted that when adopting this solution, since the bracket of the hard disk backplane 4 is cancelled, the maximum thickness of the plate-like member 1 can be allowed to be expanded to the maximum, thereby increasing the thickness space of the plate-like member 1, which is beneficial to set more sound cavities 13 on the plate-like member 1, and increase the number and volume of the sound cavities 13, which is beneficial to improve the silencer noise reduction ability of the plate-like member 1 and achieve better sound absorption and noise reduction effects.

[0138] It should be noted that the present embodiment does not limit the specific structure of the installation position, as long as the installation of the hard disk backplane 4 can be achieved.

[0139] Furthermore, please combine Figure 6 and Figure 7 In some embodiments, the plate-like member 1 is provided with first sliding parts at both ends along its length direction, and the first sliding parts are used to slide with the second sliding parts 51 of the server 5 .

[0140] That is to say, in this embodiment, the server 5 is provided with a second sliding portion 51, so that the first sliding portion and the second sliding portion 51 of the server 5 can be slidably matched to realize the installation of the plate-like member 1 in the server 5. When installing the plate-like member 1 to the server 5, the first sliding portion is aligned with the second sliding portion 51 of the server 5, and the first sliding portion is slid relative to the second sliding portion 51 of the server 5 to realize the installation of the plate-like member 1 directly on the server 5, that is, the plate-like member 1 can be slidably matched with the second sliding portion 51 of the server 5 through the first sliding portion, so as to realize convenient plug-in installation in the server 5. It can be understood that in this embodiment, the plate-like member 1 needs to meet the standard requirements of the plug-in force of the mechanical hard disk in the server 5.

[0141] It should be noted that the present embodiment does not limit the specific structure of the first sliding part and the second sliding part 51, as long as the first sliding part and the second sliding part 51 can slide and cooperate to achieve the installation of the plate-like member 1. In some embodiments, one of the first sliding part and the second sliding part 51 is a slide groove, and the other is a block structure that cooperates with the slide groove. For the convenience of design, in some embodiments, the first sliding part is the end structure at both ends of the plate-like member 1 along the length direction, and the second sliding part 51 is a slide groove. That is, in this embodiment, the two ends of the plate-like member 1 along the length direction are directly used as the first sliding part, and the slide groove can cooperate with the two ends of the plate-like member 1 along the length direction. The structure is simple and convenient for processing and manufacturing.

[0142] In addition to the above-mentioned server silencer, an embodiment of the present invention further provides a server, which includes the server silencer disclosed in any one of the above-mentioned embodiments. In addition, this embodiment does not limit the structure of other parts of the server. For the structure of other parts of the server, please refer to the relevant technology, which will not be repeated in this article.

[0143] The key point of this embodiment is that the server adopts the server silencer disclosed in any of the above embodiments. Since the above server silencer is integrated with the hard disk backplane 4 of the server 5, the server silencer is used to mute and reduce the noise passing through the hard disk backplane 4. It can be understood that the hard disk backplane 4 is located between the server hard disk and the fan in the server 5. Therefore, after the server silencer is integrated with the hard disk backplane 4, the server silencer is located on the path of the airflow driven by the fan, so that the sound cavity 13 on the plate-like member 1 of the server silencer can be used to mute and reduce the noise of the airflow passing through the hard disk backplane 4, preventing the noise from reaching the server hard disk, causing the server hard disk to resonate, and affecting the performance of the server hard disk. That is, the server silencer can avoid the influence of noise on the performance of the server hard disk by mute and reducing the noise at the hard disk backplane 4.

[0144] Moreover, the embodiment of the present invention integrates the server silencer with the hard disk backplane 4. Compared with the related art in which the server silencer is integrated with the fan bracket for installing the fan (the server silencer integrated with the fan bracket is a cylindrical sound cavity structure, and the cylindrical sound cavity structure occupies a large space), the thickness of the plate-like member 1 of the server silencer of the hard disk backplane 4 is relatively small, and the space occupied is small; moreover, the overall shape of the plate-like member 1 can be highly coincident with the overall shape of the hard disk backplane 4, which has a higher degree of practicality and less impact on the structure of the server. Therefore, the server silencer disclosed in the above embodiment has good universality and expands the application scenarios of the server silencer, especially in 1U or 2U servers, the server silencer can be directly applied.
