[0002] With the development of electronic information technology, servers, as key infrastructure supporting modern data centers, are widely used in all walks of life. When the server is working, the electronic components of the server generate a lot of heat, which affects the operation of the server. Therefore, it is necessary to effectively dissipate the heat of the server.

[0003] In the related art, fans are used to drive air flow to remove the heat emitted by electronic devices. However, when the fan rotates at high speed, it will generate noise with multiple frequency components including aerodynamic noise, electromagnetic noise and vibration noise. These noises have an adverse effect on the performance of server hard disks. Therefore, it is necessary to mute and reduce the noise of server hard disks.

[0004] In the related art, a muffler is arranged between the fan bracket and the back plate of the server to achieve noise reduction.

DETAILED DESCRIPTION

[0051] 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.

[0052] The core of the present invention is to provide a server muffler design method, a server muffler, a server, a server muffler design device, a computer-readable storage medium and a computer program product, which can realize the design of the muffler when the space is relatively limited.

[0053] Please refer to Figure 1 , an embodiment of the present invention provides a server muffler design method, comprising steps S1-S4:

[0054] S1: According to the fan bracket 2 of the server (such as Figure 3 as shown) and hard disk backplane 3 (as shown Figure 3 The actual space between the muffler and the

[0055] S2: Determine the minimum aperture of the muffler air duct 11 of the muffler according to the minimum air duct required by the fan installed on the fan bracket 2.

[0056] S3: Determine the avoidance groove 13 (such as Figure 2 shown).

[0057] S4: Based on the maximum design space, the minimum aperture and the position of the avoidance groove 13, the sound cavity 12 of the muffler is designed (such as Figure 10-12 as shown).

[0058] That is to say, the embodiment of the present invention first plans the maximum design space available for the muffler design according to the actual space between the fan bracket 2 and the hard disk backplane 3 of the server, and uses this maximum design space as the basic size of the muffler design; in addition, since the fan duct is one of the most important considerations in the muffler design process, the embodiment of the present invention determines the minimum aperture of the muffler duct 11 according to the minimum duct required by the fan, that is, the aperture of the muffler duct 11 is not less than the minimum duct required by the fan, so that after the muffler design is completed, the wind resistance does not increase or increases by no more than 5% compared with the solution without a muffler; in addition, on the basis of the maximum design space of the muffler, the maximum design space of the muffler is There may be a certain overlap between the design space and the connector 32 and the cable 31 of the hard disk backplane 3. Therefore, it is also necessary to delete the part that interferes with the connector 32 and the cable 31 of the hard disk backplane 3, that is, it is necessary to open a avoidance groove 13 at the position of the muffler corresponding to the connector 32 and the cable 31 of the hard disk backplane 3, so as to avoid the connector 32 and the cable 31 of the hard disk backplane 3 from interfering with the installation of the muffler; further, after determining the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 required to be opened in the muffler, the sound cavity 12 of the muffler is designed on this basis, and the specifications and dimensions of the sound cavity 12 can be determined according to the target frequency of the muffler, thereby reserving the design volume of the sound cavity 12.

[0059] It can be seen that before designing the sound cavity 12 of the muffler, the embodiment of the present invention first determines the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 required to be opened in the muffler, and then designs the muffler sound cavity 12 on this basis. This can make full use of the actual space between the fan bracket 2 and the hard disk backplane 3 during the design of the muffler sound cavity 12, adapt the fan air duct, and effectively avoid the connector 32 and cable 31 of the hard disk backplane 3. Therefore, it can ensure that the design of the muffler sound cavity 12 meets the conditions of limited space, thereby realizing the design of the muffler sound cavity 12 under limited space conditions.

[0060] In addition, in some embodiments, before designing the sound cavity 12 of the muffler based on the maximum design space of the muffler, the minimum aperture of the muffler air duct 11, and the position of the avoidance groove 13 of the muffler, the server muffler design method further includes:

[0061] According to the installation position of the fan bracket 2, determine the installation position of the muffler;

[0062] Based on the maximum design space, minimum aperture and position of the avoidance groove 13 of the muffler, the sound cavity 12 of the muffler is designed, including:

[0063] The sound cavity 12 of the muffler is designed based on the maximum design space, the minimum aperture of the muffler air duct 11, the position and installation position of the avoidance groove 13 of the muffler.

[0064] That is to say, in this embodiment, before designing the sound cavity 12 of the muffler, the installation position of the muffler is first determined according to the installation position of the fan bracket 2. That is, after the installation position of the muffler is determined, the sound cavity 12 of the muffler is designed. This is equivalent to excluding the size of the installation position of the muffler when designing the sound cavity 12 of the muffler to avoid overlap between the sound cavity 12 of the muffler and the installation position of the muffler.

[0065] Of course, in other embodiments, the muffler sound cavity 12 may be designed first, and after the sound cavity 12 is designed, the muffler installation part may be designed at the position where the muffler avoids the sound cavity 12.

[0066] For further information, please refer to Figure 4-Figure 9 In some embodiments, the installation position of the muffler is determined according to the installation position of the fan bracket 2, including:

[0067] The installation part includes a first sliding limit portion 14 and a first fixed portion 15. The first sliding limit portion 14 is arranged at the top of the muffler, and the first sliding limit portion 14 is used to cooperate with the second sliding limit portion 21 on the fan bracket 2 for relative sliding; the first fixed portion 15 is arranged at the bottom of the muffler, and the first fixed portion 15 is used to align and connect with the second fixed portion 22 of the fan bracket 2 when the first sliding limit portion 14 slides into place relative to the second sliding limit portion 21.

[0068] That is to say, in the design of the muffler installation part of this embodiment, the first sliding limit part 14 and the first fixing part 15 are respectively provided at the top and the bottom of the muffler, and correspondingly, the second sliding limit part 21 corresponding to the first sliding limit part 14 is provided on the fan bracket 2, and the second fixing part 22 corresponding to the first fixing part 15 is provided on the fan bracket 2. When installing the muffler, the first sliding limit part 14 and the second sliding limit part 21 are first aligned, the first sliding limit part 14 is inserted into the second sliding limit part 21, and the first sliding limit part 14 is slid relative to the second sliding limit part 21, so that the muffler slides into place. At this time, the first fixing part 15 is aligned with the second fixing part 22, and the connection between the first fixing part 15 and the second fixing part 22 can be achieved. For example, the first fixing part 15 and the second fixing part 22 can be connected by the fastener 154. It can be seen that the present embodiment utilizes the cooperation of the first sliding limit portion 14 and the first fixing portion 15 to achieve installation and fixation of the muffler, thereby achieving semi-tool-free installation of the muffler, which is beneficial to simplify the installation steps of the muffler and save fasteners 154.

[0069] In addition, in some embodiments, the installation position of the muffler is determined according to the installation position of the fan bracket 2, including:

[0070] After the muffler is installed in place on the fan bracket 2, the top surface of the muffler is coplanar with the top surface of the fan bracket 2 (such as Figure 7 as shown).

[0071] That is to say, the design of the installation part of the muffler must ensure that after the muffler is installed, the top surface of the muffler is coplanar with the top surface of the fan bracket 2, that is, after the muffler is installed, the top of the muffler is flush with the top of the fan bracket 2, so that the maximum design space of the muffler can be utilized to the greatest extent.

[0072] In addition, in some embodiments, the maximum design space of the muffler is determined according to the actual space between the fan bracket 2 and the hard disk backplane 3 of the server, including:

[0073] The plane on one side of the fan bracket 2 for mounting the muffler is used as a reference plane to evaluate the actual space between the fan bracket 2 and the hard disk backplane 3 .

[0074] That is to say, when determining the actual space between the fan bracket 2 and the hard disk backplane 3, the plane of the fan bracket 2 used to install the muffler is used as the base reference plane to determine the actual space between the fan bracket 2 and the hard disk backplane 3. Then, the maximum design space of the muffler is determined based on this actual space to ensure that after the muffler is installed on the fan bracket 2, there is a good sealing performance between the muffler and the end face of the fan duct, which is conducive to achieving maximum sound absorption and noise reduction.

[0075] In addition, in some embodiments, the position of the avoidance groove 13 required to be opened in the muffler is determined according to the arrangement positions of the connector 32 and the cable 31 of the hard disk backplane 3, including: the hard disk backplane 3 is a mechanical hard disk; the cable 31 is routed from the bottom of the muffler; and the position of the avoidance groove 13 required to be opened at the bottom of the muffler is determined according to the position of the cable 31 routed from the bottom of the muffler.

[0076] That is to say, the avoidance of the connector 32 and the cable 31 of the hard disk backplane 3 of the muffler in this embodiment is limited to the mechanical hard disk configuration, and the main consideration is the avoidance of the cable 31 from the bottom of the muffler. This is conducive to simplifying the design of the muffler sound cavity 12 and facilitating the layout of the muffler sound cavity 12.

[0077] For further information, please refer to Fig.10 and Fig.11 In some embodiments, based on the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 of the muffler, the sound cavity 12 of the muffler is designed, including:

[0078] The air duct wall of the muffler air duct 11 is used as the inner wall 121 of the sound cavity 12;

[0079] An outer wall 122 is provided on a side of the inner wall 121 radially away from the muffler air duct 11, and a gap is provided between the outer wall 122 and the inner wall 121;

[0080] A first partition plate 123 is disposed in the gap between the outer wall 122 and the inner wall 121, so that the space between the inner wall 121, the outer wall 122 and the first partition plate 123 forms a sound cavity 12;

[0081] The inner wall 121 is provided with an opening 124 which is in communication with the muffler air duct 11 .

[0082] That is to say, in this embodiment, an outer wall 122 having a gap with the inner wall 121 is arranged on the radial outer side of the muffler air duct 11, and the gap between the inner wall 121 and the outer wall 122 is divided into at least one cavity space by a first partition plate 123, so that at least one sound cavity 12 is distributed along the circumferential direction of the muffler air duct 11, and an opening 124 penetrating the wall thickness of the inner wall 121 is provided on the inner wall 121, so that the sound cavity 12 is connected with the muffler air duct 11, so that when the heat dissipation airflow passes through the muffler air duct 11, the noise can enter the sound cavity 12 from the opening 124, and the sound cavity 12 is used to absorb the noise, so as to achieve the purpose of noise reduction. It can be understood that according to the target frequency to be eliminated by the muffler, the size of the opening 124 of the muffler sound cavity 12 and the volume of the sound cavity 12 are designed, so that the sound cavity 12 design for the target frequency can be realized, and the noise reduction for the target frequency can be realized. The specific size design of the muffler sound cavity 12 can refer to the relevant technology, which will not be repeated in this article.

[0083] It can be understood that the first partition 123 not only serves to separate the sound cavity 12, but also has the function of improving the structural strength, that is, the first partition 123 is equivalent to a reinforcing rib, which can ensure the structural strength of the muffler.

[0084] In addition, it should be noted that this embodiment does not limit the specific thickness of the inner wall 121 , the outer wall 122 and the first partition plate 123 .

[0085] In some embodiments, the thickness of the inner wall 121, the outer wall 122 and the first partition 123 range from 1.5 to 2 mm respectively.

[0086] That is to say, the inventors of the present application found that: when the thickness range of the inner wall 121, the outer wall 122 and the first partition plate 123 is 1.5~2mm respectively, the sound cavity 12 can have a better sound absorption effect. At the same time, it is ensured that the inner wall 121, the outer wall 122 and the first partition plate 123 have a suitable wall thickness to avoid the inner wall 121, the outer wall 122 and the first partition plate 123 being too thick, resulting in large structural size and heavy weight. In addition, it is avoided that the inner wall 121, the outer wall 122 and the first partition plate 123 are too thin, resulting in insufficient structural strength and rigidity.

[0087] In addition, in other embodiments, based on the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 of the muffler, the sound cavity 12 of the muffler is designed, including:

[0088] The air duct wall of the muffler air duct 11 is used as the inner wall 121 of the sound cavity 12;

[0089] An outer wall 122 is provided on a side of the inner wall 121 radially away from the muffler air duct 11, and a gap is provided between the outer wall 122 and the inner wall 121 to form a sound cavity 12;

[0090] A sound-absorbing cotton is disposed on the inner surface of at least one of the outer wall 122 and the inner wall 121 facing the gap; Fig.12 As shown, the inner surface of the side wall of the sound cavity 12 is the sound-absorbing cotton installation surface 18 , and the sound-absorbing cotton can be installed by fitting it against the sound-absorbing cotton installation surface 18 .

[0091] The inner wall 121 is provided with an opening 124 which is in communication with the muffler air duct 11 .

[0092] That is to say, this embodiment arranges sound-absorbing cotton on the inner surface of the gap between the outer wall 122 and / or the inner wall 121 of the sound cavity 12 toward the outer wall 122 and the inner wall 121, and utilizes the combined effect of the sound-absorbing cotton and the sound cavity 12 to achieve superimposed optimization of the sound-absorbing effect, thereby improving the sound-absorbing and noise-reducing effect.

[0093] It can be understood that, compared with the solution of simply setting up the sound cavity 12, for the solution of setting up sound-absorbing cotton on the outer wall 122 and / or the inner wall 121 of the sound cavity 12, the inner diameter of the outer wall 122 of the muffler can be appropriately enlarged by 4 to 8 mm to facilitate the filling of the sound-absorbing cotton.

[0094] It should be noted that, in order to facilitate the arrangement of the sound-absorbing cotton, the first partition plate 123 arranged in the gap between the outer wall 122 and the inner wall 121 can be eliminated, so that the gap between the outer wall 122 and the inner wall 121 forms an integral sound cavity 12 .

[0095] Furthermore, in some embodiments, sound-absorbing cotton is arranged on the inner surface of at least one of the outer wall 122 and the inner wall 121 facing the gap between the outer wall 122 and the inner wall 121, including: the number of muffler air ducts 11 is at least two, each muffler air duct 11 corresponds to a sound cavity 12, the sound cavities 12 corresponding to at least two muffler air ducts 11 are connected, and the sound-absorbing cotton is an integrated sound-absorbing cotton arranged on the inner surface of the outer wall 122 of the connected sound cavity 12.

[0096] That is to say, this embodiment eliminates the partition plates between the sound cavities 12 corresponding to different muffler channels, so that the sound cavities 12 corresponding to at least two muffler air ducts 11 are connected, and at least two muffler air ducts 11 share the same overall sound cavity 12, which facilitates the arrangement of the sound-absorbing cotton.

[0097] Also, please refer to Fig.14 In some embodiments, after designing the sound cavity 12 of the muffler based on the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 of the muffler, the method further includes:

[0098] A weight-reducing hole 19 is provided at a position of the muffler not corresponding to the sound cavity 12 .

[0099] That is to say, after the sound cavity 12 of the muffler is designed, the muffler is designed to reduce weight, and unnecessary excess materials are removed to reduce the overall weight of the muffler.

[0100] This embodiment does not limit the specific distribution and number of the weight-reducing holes 19 .

[0101] In addition, since the structure of the muffler is relatively complex, after the structural design of the muffler is completed, the mass production process of the muffler needs to be designed in order to realize simple mold production.

[0102] Please refer to Fig.13 In some embodiments, after designing the sound cavity 12 of the muffler based on the maximum design space of the muffler, the minimum aperture of the muffler air duct 11 and the position of the avoidance groove 13 of the muffler, the method further includes:

[0103] At least two sound cavities 12 are provided along the axial direction of the muffler air duct 11;

[0104] The sound cavities 12 corresponding to the axial direction of the muffler air duct 11 are regarded as a connected complete sound cavity 12, and the muffler is cut along the axial direction perpendicular to the muffler air duct 11 to form at least two muffler modules 16;

[0105] A second partition plate 17 is provided between two adjacent muffler modules 16 to close the cut ends of the sound cavity 12 of the muffler modules 16 on both sides of the second partition plate 17;

[0106] Two adjacent muffler modules 16 are buckled together.

[0107] That is to say, this embodiment provides a method for realizing the split structure of the muffler and a corresponding assembly method, that is, firstly designing and manufacturing the corresponding sound cavity 12 along the axial direction of the muffler air duct 11 as a connected complete sound cavity 12, and then cutting the muffler along the axial direction perpendicular to the muffler air duct 11 to form at least two muffler modules 16, so that the connected complete sound cavity 12 is divided into at least two sound cavities 12 in the axial direction of the muffler air duct 11, and then at any two adjacent muffler modules 16. A second partition 17 is arranged between the muffler modules 16, so that the second partition 17 separates the two sound cavities 12 after cutting, and by interlocking the two adjacent muffler modules 16, an integral muffler is formed. At this time, the complete sound cavity 12 connected before cutting becomes at least two independent sound cavities 12 along the axial direction of the muffler air duct 11 due to the action of the second partition 17. Thus, a multi-sound cavity 12 design in the axial direction of the muffler air duct 11 is realized, which is beneficial to the sound reduction of noises of multiple different frequencies.

[0108] In addition, it should be noted that the embodiments of the present invention do not limit the specific design method of the acoustic cavity parameters. The focus of the present invention is to determine the design space of the acoustic cavity before designing the parameters of the acoustic cavity to ensure that the acoustic cavity design can be satisfied within a limited space. In some embodiments, when designing the acoustic cavity 12 of the muffler, the target frequency of the noise that the acoustic cavity 12 is used to absorb is obtained; and the frequency correction coefficient is determined; the correction frequency is obtained based on the frequency correction coefficient and the target frequency; and the parameters of the acoustic cavity 12 are designed based on the correction frequency.

[0109] That is to say, when designing the muffler sound cavity 12, this embodiment first uses the frequency correction coefficient to correct the target frequency of the noise that the sound cavity 12 is used to absorb, and then uses the corrected frequency to design the sound cavity 12 so that the frequency of the noise that can actually be eliminated by the designed sound cavity 12 is consistent with the target frequency. That is, through this method, the sound cavity 12 of the muffler can correspond to the target frequency it wants to eliminate, thereby achieving a better noise reduction effect and avoiding the situation where the sound reduction effect of the muffler sound cavity 12 designed directly according to the target frequency deviates from the target frequency.

[0110] It should be noted that this embodiment does not limit the specific method for determining the frequency correction coefficient, and those skilled in the art can obtain it through repeated experiments. The inventor of the present application found that the magnitude of the frequency correction coefficient is related to the distance from the hole wall of the opening 124 of the sound cavity 12 to the end of the muffler air duct 11, the number of sound cavities 12, and the arrangement of the sound cavities 12. In some embodiments, the value range of the frequency correction coefficient is 1.2~3.

[0111] Furthermore, in some embodiments, before designing the parameters of the acoustic cavity 12 according to the correction frequency, the method further includes:

[0112] Obtaining the target amplitude of the noise that needs to be eliminated by the acoustic cavity 12;

[0113] Obtaining a target bandwidth of noise that the acoustic cavity 12 is used to absorb;

[0114] According to the correction frequency, the parameters of the acoustic cavity 12 are designed, including:

[0115] The parameters of the acoustic cavity 12 are designed according to the correction frequency, the frequency correction coefficient, the target amplitude and the target bandwidth.

[0116] That is to say, when designing the parameters of the sound cavity 12, this embodiment also takes the target amplitude and the target bandwidth into consideration as design targets, and at the same time, uses the correction frequency to correct the target amplitude and the target bandwidth, and combines the correction frequency obtained in the above embodiment to jointly determine the parameters of the sound cavity 12. It can be seen that the muffler sound cavity 12 obtained by this embodiment can be applied to a specific frequency band, has a wide range of application, and is highly versatile.

[0117] In addition to the above-mentioned server muffler design method, an embodiment of the present invention further provides a server muffler, which is obtained according to the server muffler design method disclosed in any of the above-mentioned embodiments. That is, the server muffler is installed between the fan bracket 2 and the hard disk backplane 3 of the server, the maximum structural dimension of the server muffler is less than or equal to the actual space between the fan bracket 2 and the hard disk backplane 3, the minimum aperture of the muffler air duct 11 of the server muffler is greater than or equal to the minimum air duct required by the fan installed on the fan bracket 2, the server muffler is provided with a avoidance groove 13 for the position of the connector 32 and the cable 31 corresponding to the hard disk backplane 3, and the server muffler is provided with a sound cavity 12 at a position other than the avoidance groove 13 between the minimum aperture and the maximum structural dimension.

[0118] It can be understood that, since the server silencer is obtained according to the server silencer design method disclosed in any one of the above embodiments, the server silencer at least includes the beneficial effects of the server silencer design method disclosed in the above embodiments, which will not be repeated here.

[0119] In some embodiments, the server silencer includes a main body 1, which is in an elongated shape. The main body 1 is provided with at least two silencer air ducts 11 along its length direction. The part of the main body 1 radially away from the silencer air duct 11 is provided with a sound cavity 12 corresponding to the silencer air duct 11.

[0120] That is to say, the server silencer in this embodiment includes at least two silencer air ducts 11, corresponding to the air ducts of at least two fans on the fan bracket 2, so that the server silencer is a multi-cell structure, and all the silencer air ducts 11 are arranged along the length direction of the long strip body 1 to form an integrated structure, which is conducive to the integration and overall disassembly and assembly of the multi-cell structure.

[0121] It should be noted that the present embodiment does not limit the specific method for forming the sound cavity 12, and reference may be made to the method for forming the muffler sound cavity 12 described above.

[0122] For example, in some embodiments, the air duct wall of the muffler air duct 11 is the inner wall 121 of the sound cavity 12, and the inner wall 121 is provided with an opening 124 connected to the muffler air duct 11; the inner wall 121 is provided with an outer wall 122 on the side radially away from the muffler air duct 11, and there is a gap between the outer wall 122 and the inner wall 121; a first partition plate 123 is provided in the gap, so that the space between the inner wall 121, the outer wall 122 and the first partition plate 123 forms the sound cavity 12.

[0123] In other embodiments, the air duct wall of the muffler air duct 11 is the inner wall 121 of the sound cavity 12, and the inner wall 121 is provided with an opening 124 connected to the muffler air duct 11; the inner wall 121 is provided with an outer wall 122 on the side radially away from the muffler air duct 11, and there is a gap between the outer wall 122 and the inner wall 121 to form the sound cavity 12; at least one of the outer wall 122 and the inner wall 121 is provided with sound-absorbing cotton on the inner surface facing the gap between the outer wall 122 and the inner wall 121.

[0124] Furthermore, in some embodiments, the sound cavities 12 of at least two muffler air ducts 11 are connected, and the sound-absorbing cotton is an integrated sound-absorbing cotton arranged on the inner surface of the cavity wall of the connected sound cavities 12 .

[0125] That is to say, this embodiment arranges sound-absorbing cotton on the inner surface of the cavity wall of the sound cavity 12, and utilizes the combined effect of the sound-absorbing cotton and the sound cavity 12 to achieve superimposed optimization of the sound-absorbing effect, so as to enhance the sound-absorbing and noise-reducing capability of the server silencer; moreover, by connecting the sound cavities 12 of at least two silencer air ducts 11, the sound cavities 12 corresponding to at least two silencer air ducts 11 form an integral sound cavity 12, which facilitates the arrangement of the sound-absorbing cotton.

[0126] It should be noted that the present embodiment does not limit the specific thickness of the sound-absorbing cotton. In some embodiments, the thickness of the sound-absorbing cotton ranges from 2 to 6 mm. For example, in some embodiments, the thickness of the sound-absorbing cotton is 4 mm.

[0127] In addition, in order to avoid the connector 32 and the cable 31 of the hard disk backplane 3, in some embodiments, a side of the main body 1 away from its installation surface corresponding to at least one muffler duct 11 is provided with an avoidance groove 13, and the avoidance groove 13 extends to the bottom of the main body 1, and the installation surface is used to face the fan bracket 2 of the server.

[0128] That is to say, in this embodiment, by setting a avoidance groove 13 on the side of the main body 1 away from its installation surface and on the bottom of the main body 1 and corresponding to the position of the muffler air duct 11, in order to avoid the connector 32 and the cable 31 of the hard disk backplane 3, it is beneficial to lay out the connector 32 and the cable 31 of the hard disk backplane 3 from the bottom of the server muffler, thereby facilitating the layout.

[0129] In addition, in order to facilitate the installation of the server silencer and the fan bracket 2, in some embodiments, the main body 1 is provided with a first sliding limit portion 14 and a first fixed portion 15, and the first sliding limit portion 14 is used to slide and match with the second sliding limit portion 21 provided on the fan bracket 2 of the server to limit the position; the first fixed portion 15 is used to connect with the second fixed portion 22 provided on the fan bracket 2, and when the first sliding limit portion 14 and the second sliding limit portion 21 slide and fit into place, the first fixed portion 15 is aligned with the second fixed portion 22.

[0130] According to the above content about determining the installation position of the muffler, it can be known that the present embodiment utilizes the cooperation of the first sliding limit portion 14 and the first fixing portion 15 to achieve the installation and fixation of the server muffler, thereby achieving semi-tool-free installation of the server muffler, which is beneficial to simplify the installation steps of the server muffler, save fasteners 154, and facilitate installation.

[0131] Furthermore, the present embodiment does not limit the specific structures of the first sliding limit portion 14 and the first fixing portion 15 , as long as the above-mentioned installation method of the server muffler can be realized.

[0132] In some embodiments, one of the first sliding limit portion 14 and the second sliding limit portion 21 is a T-shaped groove or a dovetail groove, and the other is a T-shaped protrusion or a dovetail protrusion.

[0133] It is understandable that the T-slot or dovetail slot extends to the top end face of the body 1 to form an open slot, so that it is convenient for the T-shaped protrusion or dovetail protrusion to enter the T-slot or dovetail slot, thereby realizing relative sliding between the T-slot and the T-shaped protrusion or the dovetail slot and the dovetail protrusion. In addition, it is understandable that when the server muffler slides into place, the T-slot cooperates with the T-shaped protrusion, or the dovetail slot cooperates with the dovetail protrusion, which can limit the body 1 in a direction perpendicular to the thickness of the body 1.

[0134] In addition, in some embodiments, the first fixing portion 15 includes a semicircular fixing hole 151, a first giveway groove 152 and a second giveway groove 153. The semicircular fixing hole 151 is arranged at one end of the main body 1 away from the first sliding limit portion 14, and penetrates the main body 1 along the thickness direction of the main body 1; the first giveway groove 152 is connected to the semicircular fixing hole 151, and is arranged on one side of the main body 1 along the thickness direction of the main body 1, and the first giveway groove 152 is used to avoid the second fixing portion 22; the second giveway groove 153 is connected to the semicircular fixing hole 151, and is arranged on one side of the main body 1 away from the first giveway groove 152 along the thickness direction of the main body 1, and the second giveway groove 153 is used to avoid the installation of the fastener 154 passing through the semicircular fixing hole 151.

[0135] That is to say, this embodiment is fixed to the fan bracket 2 by the fastener 154 passing through the semicircular fixing hole 151. The fastener 154 may include a head pressed at one end of the semicircular fixing hole 151. The second make way groove 153 can avoid the installation of the fastener 154, so that the fastener 154 can pass through the second make way groove 153 and then through the semicircular fixing hole 151; in addition, the first make way groove 152 avoids the second fixing portion 22 on the fan bracket 2. For example, the second fixing portion 22 can be a rivet nut, and the rivet nut is located in the first make way groove 152, so that the fastener 154 can pass through the semicircular fixing hole 151 and then be connected with the rivet nut.

[0136] It should be noted that the present embodiment does not limit the specific shapes of the first clearance groove 152 and the second clearance groove 153, as long as the first clearance groove 152 can avoid the second fixing portion 22, and the second clearance groove 153 can avoid the installation of the fastener 154. In some embodiments, the first clearance groove 152 is a U-shaped groove, and the second clearance groove 153 is a semicircular groove.

[0137] In some embodiments, the main body 1 includes at least two muffler modules 16 and a second partition 17 arranged between any two adjacent muffler modules 16. The muffler module 16 and the second partition 17 are assembled and docked along the axial direction of the muffler air duct 11 to form at least two sound cavities 12 along the axial direction of the muffler air duct 11. Any two adjacent muffler modules 16 are snap-fitted and connected.

[0138] It can be understood that this structure corresponds to the split structure implementation method and the corresponding assembly method of the server silencer described above. A second partition plate 17 is provided between at least two silencer modules 16. The second partition plate 17 is used to close the sound cavity 12 of two adjacent silencer modules 16 toward one side of the second partition plate 17 to form a sound cavity 12 structure having only an opening 124. This is conducive to forming the silencer module 16 by cutting in a direction perpendicular to the silencer air duct 11, and then forming more than two sound cavities 12 along the axial direction of the silencer air duct 11, which is conducive to realizing low-cost large-scale production of the cavity part of the sound cavity 12, and by designing different sound cavity 12 parameters, it is possible to realize the design of sound cavity 12 with multiple different silencer frequencies.

[0139] Furthermore, in some embodiments, the body 1 is provided with a weight-reducing hole 19 .

[0140] It should be noted that the present embodiment does not limit the specific location, shape, and number of the weight-reducing holes 19 , as long as the design of the weight-reducing holes 19 can be realized.

[0141] In addition to the above-mentioned server muffler design method and server muffler, an embodiment of the present invention further provides a server, which includes the server muffler disclosed in any one of the above-mentioned embodiments.
