Description

Technical Field

[0001] This application relates to the field of server technology. ， In particular, it relates to a shock absorption device and a computer device. Background Technology

[0002] In related technologies, air cooling devices are often used to control the temperature of computer equipment. However, during operation, air cooling devices may affect the performance of some hardware inside the computer equipment, or even cause permanent damage to that hardware. Summary of the Invention

[0003] The purpose of this application is to provide a shock-absorbing device and a computer device to mitigate the impact of the heat dissipation device on the performance and mechanical damage of the target hardware inside the computer device during operation.

[0004] In a first aspect, embodiments of this application provide a shock-absorbing device for computer equipment, the computer equipment including target hardware and a heat dissipation device. The shock-absorbing device includes: an annular seal, a shock-absorbing structure, an exhaust device, a sensing module, and a control module. The inner region of the annular seal is used to accommodate the heat dissipation device.

[0005] The annular seal has a cavity that accommodates a shock-absorbing structure, which is housed within the cavity. The cavity is connected to the air passage of the exhaust device. Both the sensing module and the exhaust device are electrically connected to the control module. The sensing module collects vibration reference information of the annular seal within a preset time period and transmits this information to the control module. The control module controls the exhaust device to perform an exhaust operation when the vibration reference information of the annular seal within the preset time period meets the vibration suppression execution condition of the target hardware at a sensitive frequency. When the vibration reference information of the annular seal within the preset time period meets the vibration suppression interruption condition of the target hardware at a sensitive frequency, the control device stops the exhaust operation.

[0006] With the above technical solution, the inner region of the annular seal is open on both sides, ensuring that the annular seal does not obstruct ventilation for the computer equipment when the heat dissipation device is housed within it. Furthermore, the cavity of the annular seal accommodates a shock-absorbing structure. Therefore, during operation, although the heat dissipation device generates vibrations, these vibrations are absorbed by the shock-absorbing structure within the cavity of the annular seal, thereby suppressing the impact of vibrations on the performance of the target hardware within the computer equipment and reducing the likelihood of mechanical damage to the target hardware.

[0007] Furthermore, when the vibration frequency of the vibration wave is constant, the lower the air pressure inside the cavity, the shorter the propagation wavelength of the vibration wave inside the cavity, and the easier it is for the vibration wave to be absorbed by the shock-absorbing structure inside the cavity. The more energy of the vibration wave is lost in the shock-absorbing structure, the more energy is lost. The vibration reference information of the annular seal within a preset time period can indicate the degree of influence of the heat dissipation device on the target hardware. Therefore, when the cavity of the annular seal is connected to the air passage of the exhaust device, and both the sensing module and the exhaust device are electrically connected to the control module, the control module can obtain the vibration reference information of the annular seal within a preset time period collected by the sensing module, and use the vibration reference information of the annular seal within a preset time period to decide whether to perform the exhaust operation, thereby adjusting the energy loss of the vibration wave during its propagation in the cavity.

[0008] When the vibration reference information of the annular seal within a preset time period meets the vibration suppression interruption condition of the target hardware at the sensitive frequency, it indicates that the energy dissipation of the vibration wave in the cavity is appropriate. The vibration wave energy can be absorbed by the shock-absorbing structure within the annular seal, reducing the impact of the vibration wave on the performance and mechanical damage of the target hardware. Therefore, the exhaust device can be controlled to stop its exhaust operation, maintaining the annular seal's energy dissipation capability. Conversely, when the vibration reference information of the annular seal within a preset time period meets the vibration suppression execution condition of the target hardware at the sensitive frequency, it indicates that although the annular seal provides vibration damping for the heat dissipation device, the propagation wavelength of the vibration wave in the cavity is too long, resulting in insufficient energy dissipation. Therefore, the absorption of the vibration wave by the shock-absorbing structure within the annular seal is insufficient to alleviate the impact of the heat dissipation device on the target hardware. In this case, the control module can control the exhaust device to perform an exhaust operation, shortening the propagation wavelength of the vibration wave in the cavity, thereby increasing the energy dissipation of the vibration wave and mitigating the impact of the heat dissipation device on the performance and mechanical damage of the target hardware within the computer equipment.

[0009] In one possible implementation, the cavity includes an annular cavity disposed within the annular seal. This annular cavity is annularly disposed within the heat dissipation device; the shock-absorbing structure is spaced at least between itself and the cavity wall of the annular cavity near the inner region of the ring. During operation of the heat dissipation device, when the generated vibration waves propagate towards the annular seal, they first contact the cavity wall of the annular cavity near the inner region of the ring. The vibration waves are not directly absorbed by the shock-absorbing structure within the cavity; instead, they propagate to the shock-absorbing structure via the air within the space. This prolongs the energy dissipation time of the vibration waves, allowing the shock-absorbing structure to absorb as much energy as possible, thus avoiding damage to the target hardware caused by incomplete energy absorption when the shock-absorbing structure directly acts on the object.

[0010] In one possible implementation, the shock-absorbing structure includes a porous structure. The control module controls the exhaust device to perform an exhaust operation, reducing the air pressure inside the cavity and shortening the propagation wavelength of the vibration wave within the cavity. This makes it easier for the vibration wave to enter the pores of the porous structure, resulting in more vibration waves reflecting back and forth within the pores. The vibration waves rub against the inner walls of the pores, thereby consuming more energy and improving the shock absorption capacity of the shock-absorbing structure. This further mitigates the impact of the heat dissipation device on the performance and mechanical damage of the target hardware.

[0011] In one possible implementation, the control module determines the vibration amplitude change information corresponding to a sensitive frequency point based on the vibration reference information of the annular seal within a preset time period. If the vibration amplitude change information corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing, it is confirmed that the vibration reference information of the annular seal within the preset time period meets the vibration suppression interruption condition. In this case, the vibration suppression interruption condition can be considered to include: the vibration amplitude change information corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing.

[0012] When the vibration amplitude at the sensitive frequency point shows a trend of first decreasing and then increasing, it indicates that the air pressure inside the cavity of the annular seal is optimal when the vibration amplitude at the sensitive frequency point is at its minimum. Furthermore, the propagation wavelength and speed of the vibration wave within the cavity are suitable, ensuring optimal energy dissipation. As the vibration amplitude at the sensitive frequency point begins to rise from its minimum value, the air pressure inside the cavity of the annular seal becomes unfavorable for energy dissipation. Therefore, when a trend of first decreasing and then increasing vibration amplitude at the sensitive frequency point is detected, the exhaust device is controlled to stop exhausting to prevent further reduction in the energy dissipation capacity of the vibration wave within the cavity.

[0013] In one possible implementation, the control module is used to, when the exhaust device is in a stopped state, if it detects an increase in vibration amplitude at a sensitive frequency, confirming that the vibration reference information of the annular seal within a preset time period meets the vibration suppression execution condition. In this case, it can be assumed that the vibration suppression execution condition, when the exhaust device is in a stopped state, includes an increase in vibration amplitude at the sensitive frequency.

[0014] When the exhaust device is in a stopped state, the vibration amplitude corresponding to the sensitive frequency point shows an increasing trend, indicating that the sealing performance of the annular seal is poor. This allows air to enter the cavity of the annular seal, causing the air pressure inside the cavity to gradually increase. Consequently, the propagation wavelength of the vibration wave in the cavity also gradually increases, thereby shortening the residence time of the vibration wave in the cavity and reducing the absorption capacity of the annular seal for vibration waves. Therefore, when the exhaust device is in a stopped state, it can be controlled to restart the exhaust operation to restore the energy dissipation capacity of the annular seal for vibration waves and prevent the vibration waves from adversely affecting the target hardware.

[0015] In one possible implementation, the control module is used to, while the exhaust device is in operation, confirm that the vibration reference information of the annular seal within a preset time period meets the vibration suppression execution condition if it detects a decrease in vibration amplitude at a sensitive frequency. In this case, the vibration suppression execution condition includes a decrease in vibration amplitude at the sensitive frequency.

[0016] When the exhaust device is in operation, the vibration suppression execution conditions, including the vibration amplitude corresponding to the sensitive frequency, show a decreasing trend. This indicates that as the cavity pressure of the annular seal decreases, the absorption capacity of the annular seal for vibration waves continues to decrease, and there is room for further decrease. Therefore, the exhaust device can be controlled to continuously perform exhaust operation to further optimize the energy dissipation capacity of the annular seal for vibration waves, thereby better preventing the adverse effects of vibration waves on the target hardware.

[0017] In one possible implementation, the computer device further includes a baseboard management controller. The sensing module is also used to send an alarm indication to the baseboard management controller if it detects an increase in vibration amplitude at a sensitive frequency while the exhaust device is in operation. In this way, the baseboard management controller can perform relevant operations in response to the alarm indication to reduce the impact of the heat dissipation device on the performance and mechanical damage of the target hardware.

[0018] In one possible implementation, the sensing module is also used to collect the operating parameters of the exhaust device and transmit these parameters to the control module. Considering that the operating parameters of the exhaust device may fluctuate during operation, the control module is also used to control the exhaust device to stop operating when the operating parameters meet the overload conditions. This achieves the purpose of protecting the exhaust device.

[0019] In one possible implementation, the operating parameters of the exhaust device include its operating power, and the overload operating condition includes the operating power exceeding a preset operating power. For example, after the exhaust device is started, its operating power gradually increases as the air pressure inside the cavity decreases. When the operating power reaches the preset operating power, it indicates that the exhaust device has reached its operating limit. If the exhaust device continues to operate, it may be damaged. Therefore, the exhaust device can be controlled to stop working to prevent damage due to overload operation.

[0020] Secondly, embodiments of this application provide a computer device, including target hardware, a heat dissipation device, and a shock absorption device, wherein the shock absorption device is the shock absorption device described in the first aspect or any possible implementation of the first aspect.

[0021] The heat dissipation device is located within the annular seal of the vibration damping device, which is used to suppress the vibration amplitude of the vibration waves generated by the heat dissipation device based on the sensitive frequency of the target hardware.

[0022] In one possible implementation, the computer device further includes a baseboard management controller. The control module and target hardware included in the vibration damping device are both electrically connected to the baseboard management controller. The baseboard management controller is used to acquire the target hardware's response information to vibration frequency, and transmit this response information to the control module. The control module is also used to determine the sensitive frequency points of the target hardware based on its response information.

[0023] The beneficial effects of the second aspect or a possible implementation of the embodiments of this application are similar to the beneficial effects of the first aspect or any possible implementation of the first aspect, and will not be repeated here. Attached Figure Description

[0029] This application provides a shock-absorbing device that can be applied to computer equipment, which can be a general-purpose computing device or a dedicated computing device. For example, the computer equipment may be a server or a switch, etc. This application does not limit the specific type of computing equipment.

[0030] Figure 1 A schematic diagram of the structure of a computing device provided in an embodiment of this application is shown. Figure 1 As shown, the computing device 100 in this embodiment may include target hardware 101, a heat dissipation device 102, and a vibration damping device 103. The vibration damping device 103 can be used to suppress the vibration amplitude of the vibration wave generated by the heat dissipation device 102 based on the sensitive frequency of the target hardware 101.

[0031] like Figure 1As shown in the embodiments of this application, the sensitive frequency of the target hardware 101 can be considered as the vibration amplitude of the vibration wave at the sensitive frequency, which has the strongest impact on the performance and mechanical damage of the target hardware 101. Therefore, by suppressing the vibration amplitude of the vibration wave generated by the heat dissipation device 102 based on the sensitive frequency of the target hardware 101, the impact of the vibration wave of the heat dissipation device 102 on the performance and mechanical damage of the target hardware 101 can be reduced.

[0032] In one alternative approach, such as Figure 1 As shown, the computing device 100 may further include a baseboard management controller 104, which can be electrically connected to the target hardware 101 and the vibration damping device 103. The baseboard management controller 104 is used to acquire the response information of the target hardware 101 to the vibration frequency and transmit the response information of the target hardware 101 to the vibration damping device 103. The vibration damping device 103 can determine the sensitive frequency of the target hardware 101 based on the response information of the target hardware 101 to the vibration frequency.

[0033] Optional, such as Figure 1 As shown, the baseboard management controller 104 can obtain the identity information of the target hardware 101 from the target hardware 101, and obtain the response information of the target hardware 101 to the vibration frequency from the Peripheral Component Interconnect (PCI) file based on the identity information of the target hardware 101, and then transmit the response information of the target hardware 101 to the vibration frequency to the vibration damping device 103.

[0034] like Figure 1 As shown in the embodiments of this application, the heat dissipation device 102 may include a fan, a ventilator, or other equipment with ventilation functions. In the embodiments of this application, the target hardware 101 may include a hard disk, a central processing unit (CPU), a graphics processing unit (GPU), a graphics card, and a network card, but is not limited to these.

[0035] Optional, such as Figure 1 As shown, the baseboard management controller 104 is connected to a hard disk (e.g., a mechanical hard disk or a solid-state hard disk) via a hard disk controller 101A; the baseboard management controller 104 is connected to a complex programmable logic device 101B, which can control a central processing unit, a graphics card, a network card, and a network card graphics processor; the baseboard management controller 104 is also connected to a fan and a vibration damping device 103, which can suppress the vibration generated by the fan on the target hardware 101 (e.g., a hard disk).

[0036] Among them, such as Figure 1As shown, the baseboard management controller 104 is typically integrated on the motherboard of the computing device 100, essentially functioning as a lower-performance computer running a simplified operating system and software. In one example, the baseboard management controller 104 can acquire monitoring information such as temperature, voltage, and power consumption of various components, including the central processing unit, memory, and hard disk, via a communication link. It can also transmit the monitored information to the vibration damping device 103 to assist in suppressing fan vibration and mitigating the adverse effects of fan vibration on the target hardware 101 (such as the hard disk).

[0037] Optional, such as Figure 1 As shown, the baseboard management controller 104 also communicates with modules with management functions, such as the basic input / output system, complex programmable logic device 101B, heat dissipation device 102, network card, and shock absorption device 103, through a communication link to directly or indirectly control the operating status of each component of the computing device 100, such as sending commands to the basic input / output system and complex programmable logic device 101B, or controlling the ventilation parameters of the heat dissipation device.

[0038] This application provides a vibration damping device that can be used in a computing device, which includes target hardware and a heat dissipation device. This vibration damping device can mitigate the performance impact and mechanical damage to the target hardware within the computing device caused by the heat dissipation device during operation.

[0039] Figure 2 A schematic diagram of the basic structure of the shock absorption device according to an embodiment of this application is shown. Figure 3 A schematic diagram illustrating the electrical connections between the sensing module, the exhaust device, and the control module according to an embodiment of this application is shown. Figure 2 and Figure 3 As shown, the shock absorption device 200 of this application embodiment includes: annular seal 201, exhaust device 202, sensing module 203, control module 204 and shock absorption structure 205.

[0040] like Figure 2 As shown, the inner region of the annular seal 201 can be considered as a through hole along the axial direction of the annular seal 201, so that both sides of the inner region of the annular seal 201 (distributed along the axial direction of the annular seal 201) are open to accommodate the heat dissipation device 301. In this way, when the heat dissipation device 301 is accommodated in the inner region of the annular seal 201, the annular seal 201 will not affect the ventilation provided by the heat dissipation device 301 for the computing device.

[0041] like Figure 2As shown, the annular seal 201 has a cavity for accommodating the shock-absorbing structure 205, which is housed within the cavity. When the heat dissipation device 301 is operating, although it generates vibration waves, these waves are absorbed by the shock-absorbing structure 205 housed within the cavity of the annular seal 201. This suppresses the impact of the heat dissipation device 301's vibration on the performance of the target hardware within the computing device and reduces the likelihood of mechanical damage to the target hardware.

[0042] like Figure 2 As shown, the annular seal 201 can be a shell with an inner cavity. The shape of the cavity can be set according to actual needs. For example, the cavity includes an annular cavity disposed inside the annular seal 201. In this case, under the shape limitation of the annular inner cavity, the shock-absorbing structure 205 can be considered as an annular shock-absorbing structure. In this way, when the vibration wave generated by the heat dissipation device 301 propagates in different directions, the shock-absorbing structure 205 can absorb the vibration wave from different directions, thereby better suppressing the vibration wave.

[0043] like Figure 2 As shown, when there is a gap between the shock-absorbing structure 205 and the cavity wall near the inner region of the annular cavity, when the heat dissipation device 301 is working, the vibration wave generated by the heat dissipation device 301 propagates towards the annular seal 201 and will first contact the cavity wall near the inner region of the annular cavity. Since there is a gap between the shock-absorbing structure 205 and the cavity wall near the inner region of the annular cavity, the vibration wave will not be directly absorbed by the shock-absorbing structure 205 in the cavity. Instead, it will propagate to the shock-absorbing structure 205 using the air in the gap as the propagation medium. This can prolong the energy dissipation time of the vibration wave, so that the shock-absorbing structure 205 can absorb the energy of the vibration wave as much as possible. This avoids the problem of damage to the target hardware caused by the incomplete absorption of vibration wave energy by the shock-absorbing structure 205 when it directly acts on the shock-absorbing structure 205.

[0044] like Figure 2 As shown, when the vibration frequency of the vibration wave is constant, the lower the air pressure inside the cavity, the shorter the propagation wavelength of the vibration wave within the cavity, and the easier it is for the vibration wave to be absorbed by the shock-absorbing structure inside the cavity. Consequently, more energy is lost in the shock-absorbing structure. Therefore, the cavity can be connected to the exhaust device 202 via an air passage, allowing the exhaust device 202 to perform exhaust operations on the cavity as needed. Here, the exhaust device 202 can be a device with only an exhaust function, or it can be a device with both exhaust and inflation functions, such as an air pump.

[0045] like Figure 2 and Figure 3As shown, in this embodiment of the application, both the sensing module 203 and the exhaust device 202 are electrically connected to the control module 204. In this case, the sensing module 203 is used to collect vibration reference information of the annular seal 201 within a preset time period and transmit this vibration reference information to the control module 204. The control module 204 can determine whether to control the exhaust device 202 to perform an exhaust operation based on the vibration reference information of the annular seal 201 within the preset time period.

[0046] In one alternative approach, such as Figure 2 and Figure 3 As shown, the control module 204 is used to ensure that the vibration reference information of the annular seal 201 within a preset time meets the vibration suppression execution condition of the target hardware at the sensitive frequency. This indicates that although the annular seal 201 is used to dampen the heat dissipation device 301, the propagation wavelength of the vibration wave in the cavity is too long, resulting in insufficient energy dissipation. Therefore, the absorption of vibration waves by the shock-absorbing structure 205 in the annular seal 201 is insufficient to alleviate the impact of the heat dissipation device 301 on the target hardware. At this time, the exhaust device 202 can be controlled to perform an exhaust operation to shorten the propagation wavelength of the vibration wave in the cavity, thereby increasing the energy dissipation of the vibration wave and alleviating the performance impact and mechanical damage of the heat dissipation device 301 on the target hardware in the computing device.

[0047] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the control module 204 can monitor the operating status of the exhaust device 202. The vibration suppression execution conditions differ depending on the operating status of the exhaust device 202. In one example, if the control module 204 detects that the exhaust device 202 is in a stopped state, and if the vibration reference information of the annular seal 201 within a preset time period meets the vibration suppression execution conditions of the target hardware at the sensitive frequency, it can control the exhaust device 202 to start the exhaust operation. If the control module 204 detects that the exhaust device 202 is in a running state, and if the vibration reference information of the annular seal 201 within a preset time period meets the vibration suppression execution conditions of the target hardware at the sensitive frequency, it can control the exhaust device 202 to maintain the exhaust operation.

[0048] Optional, such as Figure 2 and Figure 3As shown, the control module 204 can be used to determine the vibration amplitude change information corresponding to the sensitive frequency point based on the vibration reference information of the annular seal 201 within a preset time period. When the exhaust device 202 is in a stopped state, if the vibration amplitude change information corresponding to the sensitive frequency point is detected to show an increasing trend, it is confirmed that the vibration reference information of the annular seal 201 within the preset time period meets the vibration suppression execution condition. At this time, it can be considered that when the exhaust device 202 is in a stopped state, the vibration suppression execution condition includes the vibration amplitude corresponding to the sensitive frequency point showing an increasing trend.

[0049] like Figure 2 and Figure 3 As shown, when the exhaust device 202 is in a stopped state, the vibration amplitude corresponding to the sensitive frequency point shows an increasing trend in the vibration suppression execution conditions, indicating that the cavity sealing performance of the annular seal 201 is poor, allowing air to enter the cavity of the annular seal 201 and causing the air pressure inside the cavity of the annular seal 201 to gradually increase. Correspondingly, the propagation wavelength of the vibration wave in the cavity will also gradually increase, thereby shortening the residence time of the vibration wave in the cavity and reducing the absorption capacity of the annular seal 201 for vibration wave energy. Therefore, when the exhaust device 202 is in a stopped state, the exhaust device 202 can be controlled to resume the exhaust operation to restore the energy dissipation capacity of the annular seal 201 for vibration waves and prevent the vibration waves from adversely affecting the target hardware.

[0050] Optional, such as Figure 2 and Figure 3 As shown, the control module 204 can be used to determine the vibration amplitude change information corresponding to the sensitive frequency point based on the vibration reference information of the annular seal 201 within a preset time period when the exhaust device 202 is in operation. If the vibration amplitude change information corresponding to the sensitive frequency point is detected to show a decreasing trend, it is confirmed that the vibration reference information of the annular seal 201 within the preset time period meets the vibration suppression execution condition. At this time, the vibration suppression execution condition includes the vibration amplitude corresponding to the sensitive frequency point showing a decreasing trend.

[0051] like Figure 2 and Figure 3 As shown, when the exhaust device 202 is in operation, the vibration suppression execution conditions, including the vibration amplitude corresponding to the sensitive frequency, show a decreasing trend. This indicates that as the cavity pressure of the annular seal 201 decreases, the absorption capacity of the annular seal 201 for vibration waves continues to decrease, and there is room for further decrease. Therefore, the exhaust device 202 can be controlled to continuously perform exhaust operation to further optimize the energy dissipation capacity of the annular seal 201 for vibration waves, thereby better preventing the adverse effects of vibration waves on the target hardware.

[0052] like Figure 2 and Figure 3 As shown, the shock-absorbing structure 205 can be a porous structure, such as porous silicone or shock-absorbing cotton, but is not limited to these. When the exhaust device performs exhaust operation, it can reduce the air pressure inside the cavity, making the air pressure inside the cavity relatively low, thereby shortening the propagation wavelength of the vibration wave inside the cavity. When the propagation wavelength of the vibration wave inside the cavity is relatively short, the vibration wave is more likely to enter the pores of the porous structure, causing more vibration waves to be reflected back and forth within the pores of the porous structure. In this way, the vibration wave achieves friction with the inner wall of the pores through back and forth reflection within the pores, thereby consuming more energy of the vibration wave and improving the vibration wave absorption capacity of the shock-absorbing structure 205, so as to further mitigate the performance impact and mechanical damage of the heat dissipation device 301 on the target hardware.

[0053] In one alternative approach, such as Figure 2 and Figure 3 As shown, when the vibration reference information of the annular seal 201 within a preset time period meets the vibration suppression interruption condition of the target hardware at the sensitive frequency point, it indicates that the energy loss of the vibration wave in the cavity is appropriate. The vibration wave energy can be absorbed by the shock-absorbing structure 205 in the annular seal 201, reducing the impact of the vibration wave on the performance of the target hardware and the degree of mechanical damage. Therefore, the exhaust device 202 can be controlled to stop the exhaust operation to maintain the energy dissipation capability of the annular seal against the vibration wave.

[0054] Optional, such as Figure 2 and Figure 3 As shown, the control module 204 can determine the vibration amplitude change information corresponding to the sensitive frequency point based on the vibration reference information of the annular seal 201 within a preset time period. If the vibration amplitude change information corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing, it is confirmed that the vibration reference information of the annular seal 201 within the preset time period meets the vibration suppression interruption condition. At this time, it can be considered that the vibration suppression interruption condition includes: the vibration amplitude change information corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing.

[0055] like Figure 2As shown, when the vibration amplitude change information corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing, it indicates that when the vibration amplitude corresponding to the sensitive frequency point is at its minimum, the air pressure inside the cavity of the annular seal 201 is at its optimal pressure, and the propagation wavelength and speed of the vibration wave within the cavity are suitable, ensuring that the energy loss of the vibration wave within the cavity is optimal. When the vibration amplitude corresponding to the sensitive frequency point begins to increase from its minimum value, the air pressure inside the cavity of the annular seal 201 becomes unfavorable for the energy loss of the vibration wave within the cavity. Therefore, when a trend of first decreasing and then increasing is detected in the vibration amplitude corresponding to the sensitive frequency point, the exhaust device 202 is controlled to stop the exhaust operation, thereby preventing further deterioration of the vibration suppression effect of the annular seal 201 at the sensitive frequency point.

[0056] like Figure 2 As shown, considering that the vibration amplitude corresponding to the sensitive frequency point may fluctuate in a very short time, in order to avoid misjudgment caused by the vibration amplitude corresponding to the sensitive frequency point fluctuating in a very short time, vibration reference information of the annular seal 201 within a preset time period is collected. Based on the vibration reference information of the annular seal 201 within a preset time period, it is detected whether the vibration amplitude corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing over a relatively long period of time, which can avoid misjudgment caused by short-term fluctuations in vibration amplitude.

[0057] In one possible implementation, such as Figure 2 and Figure 3 As shown, the sensing module 203 is also used to send an alarm indication to the baseboard management controller if it detects an increase in vibration amplitude at a sensitive frequency when the exhaust device 202 is in operation. This allows the baseboard management controller to perform target hardware protection operations in response to the alarm indication. For example, the baseboard management controller can control the heat dissipation device 301 to stop working, thereby reducing the impact of the heat dissipation device 301 on the performance and mechanical damage of the target hardware.

[0058] In one alternative approach, such as Figure 2 and Figure 3 As shown, the sensing module 203 may include a first sensor 2031, which may be disposed on the outer wall of the annular seal 201 to intermittently collect vibration reference information of the annular seal 201 and transmit it to the control module 204. Considering that during the operation of the heat dissipation device 301, if the vibration suppression function of the annular seal 201 is poor, the vibration wave generated by the heat dissipation device 301 will cause the annular seal 201 to vibrate to a certain extent, when the first sensor 2031 is an acceleration sensor, the acceleration of the annular seal 201 under the action of the vibration wave can be collected by the acceleration sensor.

[0059] And, as Figure 2 As shown, the greater the acceleration of the annular seal 201 under the action of the vibration wave, the higher the vibration amplitude of the vibration wave. Therefore, the vibration reference information can be set to include the acceleration information of the annular seal 201. The controller can obtain the vibration amplitude of the annular seal 201 at different vibration frequencies based on the acceleration information of the annular seal 201, and then obtain the vibration amplitude corresponding to the sensitive frequency point from the vibration amplitude of the annular seal 201 at different vibration frequencies.

[0060] like Figure 2 and Figure 3 As shown, when the preset duration includes multiple monitoring points, and the time interval between two adjacent monitoring points can be in the millisecond range, when the control module 204 acquires the moving acceleration of the annular seal 201 at multiple monitoring points, the control module 204 can acquire the vibration amplitude of the annular seal 201 at different vibration frequencies at each monitoring point, and extract the vibration amplitude corresponding to the sensitive frequency point from the vibration amplitude of different vibration frequencies at each monitoring point. In this way, the vibration amplitudes corresponding to the sensitive frequencies at multiple monitoring points can constitute the vibration amplitude change information corresponding to the sensitive frequency point, and then based on the vibration amplitude change information corresponding to the sensitive frequency point, the vibration amplitude change trend corresponding to the sensitive frequency point is determined.

[0061] like Figure 2 and Figure 3 As shown, if the detection exhaust device 202 is in operation, the vibration amplitude change trend corresponding to the sensitive frequency point includes a decreasing trend, indicating that the vibration suppression effect of the annular seal 201 at the sensitive frequency point is getting better and better. If the detection exhaust device 202 is in operation, the vibration amplitude change trend corresponding to the sensitive frequency point includes a trend of first decreasing and then increasing, indicating that the vibration suppression effect of the annular seal 201 at the sensitive frequency point is best when the vibration amplitude is at its minimum. As the vibration amplitude increases from its minimum, the vibration suppression effect of the annular seal 201 at the sensitive frequency point deteriorates from its optimal level. Therefore, when the control module 204 detects that the vibration amplitude corresponding to the sensitive frequency point shows a trend of first decreasing and then increasing, it can control the exhaust device 202 to stop the exhaust operation, thereby preventing the vibration suppression effect of the annular seal 201 at the sensitive frequency point from further deteriorating.

[0062] In one alternative approach, such as Figure 2 and Figure 3As shown, the sensing module 203 is also used to collect the operating parameters of the exhaust device 202 and transmit these parameters to the control module 204. Considering that the operating parameters of the exhaust device 202 may fluctuate during operation, the control module 204 is also used to control the exhaust device 202 to stop operating when its operating parameters meet overload conditions. This achieves the purpose of protecting the exhaust device 202.

[0063] Optional, such as Figure 2 and Figure 3 As shown, the operating parameters of the exhaust device 202 include its operating power, and the overload operating condition includes the operating power of the exhaust device 202 exceeding the preset operating power. For example, after the exhaust device 202 is started, its operating power gradually increases as the air pressure inside the cavity decreases. When the operating power of the exhaust device 202 reaches the preset operating power, it indicates that the exhaust device 202 has reached its operating limit. If the exhaust device 202 continues to operate, it may be damaged. Therefore, the exhaust device 202 can be controlled to stop working to prevent damage due to overload operation.

[0064] In one example, such as Figure 2 and Figure 3 As shown, the sensing module 203 may further include a second sensor 2032 electrically connected to the control module 204 and the exhaust device 202. This second sensor 2032 can be mounted on the exhaust device 202 or operate independently of it. The second sensor 2032 can detect the operating power of the exhaust device 202 and transmit this power to the control module 204. In this way, the second sensor 2032 can collect the operating power of the exhaust device 202 in real time and transmit it to the control module 204. This allows the control module 204 to promptly monitor whether the operating power of the exhaust device 202 exceeds a preset operating power. If the operating power exceeds the preset operating power, the control module will stop the exhaust device 202 from operating, thereby ensuring the safety of the exhaust device 202.

[0065] In one alternative approach, such as Figure 2 and Figure 3 As shown, the baseboard management controller 302 included in the computing device of this embodiment can be electrically connected to the control module 204. When the baseboard management controller 302 detects that the computing device is powered on, it can control the sensing module 203 and the exhaust device 202 to be powered on. Furthermore, the baseboard management controller 302 can also acquire the response information of the target hardware to the vibration frequency and transmit it to the sensing module 203.

[0066] Optional, such as Figure 2 and Figure 3 As shown, when the target hardware is a hard drive, the response information of the target hardware to vibration frequency can be the vibration amplitude of the hardware at different frequencies. At this time, the control module 204 can obtain the frequency with the largest vibration amplitude from the vibration amplitude of the hardware at different frequencies. This frequency is the resonance point of the hard drive and can be used as the sensitive frequency point of the hard drive.

[0067] To clearly explain the vibration reduction method of this application embodiment, taking a server as an example, the process of using a vibration reduction device to suppress the vibration wave amplitude of a fan to protect the mechanical hard drive is described. Wherein, as Figure 2 and Figure 3 As shown, the exhaust device 202 used by the shock absorption device 200 is an air pump, and the sensing module 203 includes a first sensor 2031 which is an acceleration sensor, and a second sensor 2032 which can be an air pump power detection module built into the air pump.

[0068] The resonant frequencies of key components in a hard disk drive (HDD) include: 5.6 kHz for the voice coil motor, 10.1 kHz for the read / write head and robotic arm, and 39 kHz for the electromagnetic power amplifier. Since the resonant frequencies of the voice coil motor and the read / write head and robotic arm are both within the fan's rotational speed range, vibration damping equipment needs to monitor the amplitude of vibrations at these two important frequencies and use an air pump to evacuate the cavity, thereby increasing the absorption of fan vibration energy and reducing the vibration amplitude transmitted from the fan to the key components of the HDD.

[0069] Figure 4 A schematic flowchart of a vibration reduction method according to an embodiment of this application is shown. Figure 4 As shown, the vibration reduction method of this application embodiment includes steps 401 to 407.

[0070] In step 401, when the server is powered on, the baseboard management controller controls the air pump and accelerometer to power on, obtains the identity information of the hard disk drive, looks up the table from the PCI file based on the identity information of the hard disk drive, obtains the sensitive frequency of the hard disk drive, and transmits the sensitive frequency of the hard disk drive to the control module.

[0071] Optionally, the identity information of the hard drive may include the manufacturer and type of the hard drive, while the sensitive frequency of the hard drive may be the resonant frequency at which the fan, voice coil motor and read / write head robotic arm resonate.

[0072] In step 402, the control module controls the air pump to start performing the air extraction operation, which reduces the cavity pressure of the annular seal. The air pump power detection module sends the operating power of the air pump to the control module, and the acceleration sensor transmits the acceleration information of the annular seal to the control module.

[0073] In step 403, the control module records the operating power of the air pump and the acceleration information of the annular seal at multiple sampling points. Based on the acceleration information of the annular seal and the sensitive frequency of the hard disk, the vibration amplitude of the annular seal at the sensitive frequency is determined.

[0074] The time interval between two adjacent sampling points can be set according to time conditions, such as milliseconds. By recording the operating power of the air pump and the vibration amplitude of the annular seal at the sensitive frequency point at each sampling point, it is possible to detect whether the operating power of the air pump at the current sampling point is greater than the preset operating power.

[0075] If the operating power of the air pump at the current sampling point is greater than the preset operating power, it indicates that the air pump may be damaged, and step 404 can be executed; if the current operating power of the air pump is less than or equal to the preset operating power, the trend of the vibration amplitude of the annular seal at the sensitive frequency obtained from the current sampling point and the historical vibration amplitude of the annular seal at the sensitive frequency obtained from the previous n-1 sampling points can be used to determine the trend of the vibration amplitude of the annular seal at the sensitive frequency obtained from the n sampling points.

[0076] If the vibration amplitude of the annular seal at the sensitive frequency obtained from n sampling points gradually decreases, it indicates that the air pump can continue to pump air to reduce the pressure in the cavity of the annular seal, thereby further optimizing the annular seal's ability to suppress the fan's vibration waves.

[0077] If the vibration amplitude of the annular seal at the sensitive frequency obtained from n sampling points first decreases and then increases, it indicates that the annular seal's ability to suppress the fan's vibration wave is optimal when the vibration amplitude is minimal. However, the annular seal's ability to suppress the fan's vibration wave gradually deteriorates as the vibration amplitude increases from its minimum. Therefore, step 404 can be executed to prevent further deterioration of the annular seal's ability to suppress the fan's vibration wave.

[0078] If the operating power of the air pump increases from the initial operating power to the preset operating power, and the vibration amplitude of the annular seal at the sensitive frequency point obtained from the n sampling points does not decrease or gradually increases, it indicates that the annular seal is difficult to effectively suppress the vibration amplitude at the sensitive point. Therefore, step 406 can be executed.

[0079] In step 404, the control module stops the air pump from performing the exhaust operation. If the operating power of the air pump at the current sampling point is greater than the preset operating power, the control module stops the air pump from performing the exhaust operation to prevent the air pump from being damaged due to overload.

[0080] In step 405, after the air pump stops performing the exhaust operation, the acceleration information of the annular seal is recorded again. Based on the acceleration information of the annular seal and the sensitive frequency of the hard disk, the vibration amplitude of the annular seal at the sensitive frequency is determined.

[0081] If the vibration amplitude of the annular seal at the sensitive frequency obtained from n sampling points gradually increases, it indicates that the vibration damping effect of the annular seal may be deteriorating due to some reason (such as changes in the air temperature and humidity inside the cavity of the annular seal, or the annular seal itself). Therefore, step 406 can be executed.

[0082] In step 406, the control module controls the air pump to perform an exhaust operation. When the air pump is running, if the vibration amplitude of the annular seal at the sensitive frequency obtained from the n sampling points gradually decreases, the control module controls the air pump to perform an exhaust operation to reduce the cavity air pressure of the annular seal, thereby enhancing the vibration wave absorption efficiency of the vibration-absorbing structure in the cavity, making the vibration damping function of the annular seal better and better. When the air pump is stopped, if the vibration amplitude of the annular seal at the sensitive frequency obtained from the n sampling points gradually increases, the control module controls the air pump to perform an exhaust operation, which can ensure that the vibration damping function of the annular seal is restored.

[0083] If the vibration amplitude of the annular seal at the sensitive frequency point continues to gradually increase after the control module controls the air pump to perform the exhaust operation, it indicates that the vibration damping function of the annular seal cannot be restored, and step 407 can be executed. For example, when the operating power of the exhaust device is greater than the preset operating power, the exhaust device is in an overload working state, therefore, step 407 can be executed.

[0084] In step 407, the control module sends an alarm indication to the baseboard management controller, causing the baseboard management controller to perform a hard disk protection operation in response to the alarm indication. For example, the fan may be stopped.

[0085] As can be seen, the shock absorption device of this application embodiment can suppress the vibration amplitude of the target hardware at the sensitive frequency point by combining the operating power of the fan and the moving acceleration of the annular seal with the sensitive frequency point of the hard disk, and protect the safe operation of the air pump.
