[0032] See also Figures 1 to 4 The present invention proposes a muffler assembly 10, which is applied to a server, and includes: a base 11 and a cover shell 12. The base 11 is provided with a first chamber 116, and the cover shell 12 is provided with a second chamber 126. When the cover shell 12 is covered on the base 11, the first chamber 116 and the second chamber 126 form a muffler chamber 15. The cover shell 12 is provided with a plurality of muffler holes 127, and the plurality of muffler holes 127 are all connected to the muffler chamber 15.

[0033] The muffler assembly 10 proposed in this embodiment is based on the working principle of the Helmholtz resonator to reduce the noise generated by the operation of the server. The muffler cavity is equivalent to the cavity of the resonator, and the muffler hole is equivalent to the neck. In actual use, when the noise generated by the operation of the server enters the muffler cavity 15 from the muffler hole 127, since the natural frequency of the muffler assembly 10 itself is the same as the frequency of the noise generated inside the server, the noise resonates with the air in the muffler cavity 15, consuming the energy of the noise, greatly reducing the noise intensity transmitted by the muffler assembly 10, and reducing interference with sensitive components of the mechanical hard disk inside the server.

[0034] In the silencer assembly 10 proposed in this embodiment, after the noise enters the silencer cavity 15 from the silencer hole 127, resonance occurs in the silencer cavity 15 to consume the energy of the noise, thereby reducing the interference of the noise on the mechanical hard disk, improving the IOPS performance of the mechanical hard disk, and further improving the response speed of the server.

[0035] See also Figures 2 to 3 The base 11 is provided with a spring glass bead 13 , and the inner wall of the cover shell 12 is provided with a plurality of grooves 14 corresponding to the spring glass bead 13 . The fixed end of the spring glass bead 13 is connected to the base 11 , and the free end of the spring glass bead 13 abuts against the groove 14 .

[0036] Specifically, the formula for the natural frequency of a Helmholtz resonator is It can be seen that f is the natural frequency, c is the speed of sound, V is the cavity volume, and A is the neck cross-sectional area. When the user needs to adjust the volume of the silencer cavity to change the natural frequency of the silencer assembly, he only needs to apply enough force to make the spring glass bead 13 slide out of the current groove 14, so that the cover 12 moves up / down to change the volume of the silencer cavity to change the natural frequency of the silencer assembly.

[0037] See also Figure 3 The base 11 includes: a bottom plate 111, a front end plate 112, a rear end plate 114, a first side plate 113 and a second side plate 115. The front end plate 112, the first side plate 113, the rear end plate 114 and the second side plate 115 are sequentially surrounded by the plate surface of the bottom plate 111 to form a first chamber 116. The first side plate 113 and the second side plate 115 are both provided with spring glass beads 13.

[0038] Specifically, the first chamber 116 formed by the front end plate 112, the first side plate 113, the rear end plate 114 and the second side plate 115 around the bottom plate 111, together with the second chamber 126 on the cover shell 12, constitute the muffler chamber 15. After the sound enters the muffler chamber 15 through the muffler hole 127, according to the interference principle of sound waves, sound waves of different phases are superimposed on each other, and part of the energy cancels each other out, thereby achieving the purpose of muffler. The first side plate 113 and the second side plate 115 are both connected to the spring glass bead 13, and the free end thereof is in a certain extended state when not subjected to external force. When the cover shell 12 is installed, after a certain force is applied to the cover shell 12, the free end of the spring glass bead 13 is compressed into the groove 14, and the elastic force of the spring provides a continuous clamping force to achieve a tight connection between the cover shell 12 and the base 11.

[0039] Please refer again Figure 3 Both ends of the bottom plate 111 are provided with mounting positions 1111, so that the silencer assembly 10 can be fixed at multiple points in the server chassis. Compared with single-point fixation, the stability of the silencer assembly 10 during the operation of the server is effectively improved, the displacement or damage of the silencer assembly 10 caused by resonance is reduced, and its long-term stable operation is ensured.

[0040] See also Figure 4 The cover shell 12 includes: a top plate 121, a front panel 122, a rear panel 124, a third side panel 123 and a fourth side panel 125. The front panel 122, the third side panel 123, the rear panel 124 and the fourth side panel 125 are sequentially surrounded by the edge of the top plate 121 to form a second chamber 126. The third side panel 123 and the fourth side panel 125 are both provided with a plurality of grooves 14, and a plurality of muffler holes 127 are provided on the top plate 121.

[0041] Specifically, the panel, the third side panel 123, the rear panel 124 and the fourth side panel 125 form a second chamber 126 around the top panel 121, and cooperate with the first chamber 116 of the base 11 to form a muffler chamber 15, so that after the sound enters the muffler chamber 15 through the muffler hole 127, according to the interference principle of sound waves, sound waves of different phases are superimposed on each other, and part of the energy cancels each other, thereby achieving the purpose of muffler. The multiple grooves 14 on the third side panel 123 and the fourth side panel 125 cooperate with the spring glass beads 13 of the base 11, and the elasticity of the spring glass beads 13 is utilized. When the cover 12 is assembled with the base 11, the spring glass beads 13 are inserted into the grooves 14 to provide a stable connection force. At the same time, by changing the position of the groove 14 in which the spring glass bead 13 is inserted, the relative position of the cover shell 12 and the base 11 can be adjusted. According to the principle of the Helmholtz resonator, the volume of the silencer cavity 15 is changed, thereby changing the natural frequency of the silencer assembly 10 to better match the noise frequency; the silencer hole 127 is arranged on the top plate 121 to guide the sound waves into the silencer cavity 15 for processing, thereby improving the silencer efficiency of the silencer assembly 10.

[0042] Please refer again Figure 4A plurality of grooves 14 are sequentially arranged along the height direction of the third side plate 123 and the fourth side plate 125 to adjust the volume of the muffler chamber 15, thereby matching noises of different frequencies, improving the muffler accuracy of the muffler assembly 10, and enabling the muffler assembly 10 to effectively eliminate noises of specific frequencies, thereby reducing the impact of noise on server hardware and improving the performance and stability of the server.

[0043] Please refer again Figure 4 , the spacing between adjacent grooves 14 is equal, ensuring that when adjusting the volume of the silencer chamber 15, each change in the relative position of the cover 12 and the base 11 causes the volume change of the silencer chamber 15 to be equal, so that the operator can accurately adjust the natural frequency of the silencer assembly 10 to match noises of different frequencies, thereby improving the efficiency of the adjustment.

[0044] Please refer again Figure 4 The multiple muffler holes 127 are sequentially arranged along the length and width of the top plate 121. The noise generated when the server is running is distributed in different areas. The muffler holes 127 are sequentially arranged along the length and width of the top plate 121, which can collect noise from all directions in an all-round way. The inlet range of noise entering the muffler cavity 15 is increased, ensuring that more noise enters the muffler cavity, and improving the coverage of the muffler assembly 10 for noise sources at different positions.

[0045] Please refer again Figure 4 The spacing between adjacent silencer holes 127 is equal, and the silencer holes 127 are arranged at equal spacings, ensuring that the noise is collected evenly without omissions in the area covered by the top plate 121, avoiding insufficient noise collection in some areas due to uneven density of the silencer holes 127, thereby improving the noise processing capability of the silencer assembly 10 for the noise inside the server.

[0046] See also Figure 5 The present invention further proposes a server, comprising: at least one muffler assembly 10, a fan module 20 and a hard disk module 30 as described above, wherein the fan module 20 is arranged on one side of the muffler assembly 10, and the hard disk module 30 is arranged on the other side of the muffler assembly 10.

[0047] Specifically, the muffler assembly 10 is applied to a server, so the beneficial effects of the server are the same as the beneficial effects of the muffler assembly 10 .

[0048] Compared with the prior art, the silencer assembly 10 proposed in the present invention, after the noise enters the silencer cavity 15 from the silencer hole 127, resonance occurs in the silencer cavity 15 to consume the energy of the noise, thereby reducing the interference of the noise on the mechanical hard disk, improving the IOPS performance of the mechanical hard disk, and further improving the response speed of the server.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
