Description

Technical Field

[0001] This invention relates to the field of server technology, specifically to a low-power server thermal management system and control method for edge computing. Background Technology

[0002] Low-power servers for edge computing employ low-power hardware and optimized architecture to achieve efficient, low-energy local data processing and real-time response, and are widely used in various fields. Existing low-power servers for edge computing typically use air cooling for heat dissipation. Air cooling requires opening heat dissipation channels on the server to expel internal heat. However, when the fan is not working, the heat dissipation channels are open, allowing external dust to enter the server's interior. Although dust filters are installed, they cannot completely prevent external dust from entering, and dust accumulates on the filters, affecting their permeability and thus heat dissipation. In addition, although dust filters are installed at the air inlets to filter the air, these filters are not easy to install and remove, and are inconvenient to clean. Summary of the Invention

[0003] The purpose of this invention is to provide a low-power server thermal management system and control method for edge computing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A low-power server thermal management system for edge computing includes: a fan mounted on a cover, the cover being fixedly mounted on the server body, and heat dissipation channels symmetrically opened on both sides of the server body; A removable air intake dustproof component is installed on the server body to filter the air entering the server body. A movable heat exhaust sealing assembly is connected to a removable air inlet dustproof assembly. The removable air inlet dustproof assembly moves the movable heat exhaust sealing assembly. When the fan is not working, the heat exhaust channel is sealed by the movable heat exhaust sealing assembly. The air secondary filtration component performs secondary filtration on the air to ensure air cleanliness.

[0005] Furthermore, a sealing cover is fixedly installed on the cover, the fan is located inside the sealing cover, and an air delivery pipe is fixedly installed on the sealing cover.

[0006] Furthermore, the detachable air intake dustproof assembly includes: a lightweight sealing plate, which is inserted into the air delivery pipe; Dustproof netting, which is installed on the server body; The movable support is movably installed on the server body and is used to support the dustproof net.

[0007] Furthermore, the lightweight sealing plate is connected to the movable support platform, and the lightweight sealing plate drives the movable support platform to move, thereby driving the dustproof net to move.

[0008] Furthermore, the movable heat dissipation sealing assembly includes: two support strips, which are symmetrically installed on the cover; A drive plate is connected to a support strip, and the support strip drives the drive plate to move. A channel baffle is movably connected to a drive plate, and the drive plate moves the channel baffle.

[0009] Furthermore, the support strip is movably connected to the lightweight sealing plate, and the lightweight sealing plate drives the support strip to move.

[0010] Furthermore, when the fan is not in operation, the heat dissipation channel is closed by a channel baffle.

[0011] Furthermore, the secondary air filtration assembly includes: a sealing mask, which is fixedly installed on a sealing cover, and air supply pipes are symmetrically fixedly arranged on the sealing mask; The filter cartridge is inserted into the air supply duct, and the air is filtered a second time through the filter cartridge. The filter cartridge is also locked by the support strips.

[0012] Furthermore, the server thermal management system also includes a control module, a communication module, a temperature detection module, and a drive module. The temperature detection module detects the internal temperature of the server body and feeds back the detection results to the control module through the communication module. When the internal temperature of the server body reaches the heat dissipation requirement, the control module controls the fan to work through the drive module to dissipate heat from the server.

[0013] A control method for a heat dissipation management system includes the following steps: Step 1: Temperature detection: The temperature of the server body is detected by the temperature detection module. When the temperature is abnormal, the fan will start to dissipate heat. Step 2: Locking the dust filter: When the fan is working, the airflow moves the lightweight sealing plate, which in turn moves the dust filter, locking it in place and ensuring its stability when filtering air. Step 3: Opening the heat exhaust channel: The lightweight sealing plate moves the support strips, which in turn move the drive plate under the action of the support strips, thus opening the heat exhaust channel and allowing heat to be released.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. Heat dissipation channels are provided on both sides of the server body. When the fan is not working and the server body does not need to dissipate heat, the heat dissipation channels are closed by the channel baffles. This can effectively prevent external dust from entering the server body. When the fan is working, the heat dissipation channels are open to facilitate the dissipation of heat to the outside.

[0015] 2. When the heat dissipation channel is open, as the hot air inside the server is discharged, it can also prevent external dust from entering the server. In addition, the filter cartridge can perform secondary filtration of the air to ensure the cleanliness of the air. The filter cartridge is easy to install and remove, and easy to clean.

[0016] 3. In addition, when the fan is in operation, the lightweight sealing plate will move the dust filter to lock it in place, ensuring its stability during operation. When the fan is not in operation, the dust filter is unlocked, making it easy to remove and clean. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a technical solution: like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a low-power server thermal management system for edge computing includes: a fan 22, a removable air intake dustproof component, a movable heat dissipation sealing component, and an air secondary filtration component. The fan 22 is mounted on a cover 2, which is fixed to the server body 1 by screws. Heat dissipation channels 14 are symmetrically opened on both sides of the server body 1. The removable air intake dustproof component is installed on the server body 1 and filters the air entering the server body 1. The movable heat dissipation sealing component is connected to the removable air intake dustproof component and moves the movable heat dissipation sealing component. When the fan 22 is not working, the movable heat dissipation sealing component seals the heat dissipation channel 14, effectively preventing the entry of external dust. The air secondary filtration component performs secondary filtration of the air to ensure air cleanliness and prevent dust from accumulating on the components inside the server body 1.

[0034] like Figure 4 As shown, an air inlet slot 11 is provided at one end of the server body 1, a support guide hole 12 is provided at the bottom of the air inlet slot 11, and an air inlet channel 13 is also provided at the bottom of the air inlet slot 11. Installation guide holes 15 are symmetrically provided on the inner wall of the heat exhaust channel 14, and a support rod 16 is welded and fixed on the inner wall of the server body 1 on the upper side of the heat exhaust channel 14 by welding process.

[0035] like Figure 6 As shown, a sealing cover 21 is fixedly installed on the cover 2 by bolts. The fan 22 is located in the sealing cover 21, and an air supply pipe 23 is integrally formed and fixed on the sealing cover 21. An air inlet 24 is opened on the air supply pipe 23. When the cover 2 is installed on the server body 1, the air inlet 24 is aligned with the air intake channel 13, and at this time, the end face of the air inlet 24 is in contact with the end face of the inner end face of the air intake channel 13.

[0036] In addition, symmetrical moving channels 25 are provided on both sides of the air delivery pipe 23. A support plate 26 is welded and fixed on the air delivery pipe 23 next to the moving channel 25 by welding process. A support through hole 27 is provided on the support plate 26. A mounting bracket 28 is also welded and fixed on the cover 2 by welding process. Mounting support rods 29 are symmetrically welded and fixed on the mounting bracket 28 by welding process.

[0037] like Figure 3 , Figure 5 , Figure 9 and Figure 11As shown, the detachable air intake dustproof assembly includes: a lightweight sealing plate 4, a dustproof net 6, and a movable support 62. The lightweight sealing plate 4 is inserted into the air delivery pipe 23. When the fan 22 is not in operation, the lightweight sealing plate 4 blocks the air inlet 24.

[0038] A T-shaped connecting plate 41 is welded to the lightweight sealing plate 4. The T-shaped connecting plate 41 is inserted into the moving channel 25. A sealing strip 42 is welded to the T-shaped connecting plate 41. The sealing strip 42 is located outside the air supply pipe 23 and contacts the outer wall of the air supply pipe 23 to seal the moving channel 25. A mating protrusion 43 is integrally formed and fixed on the sealing strip 42. A connecting rod 44 is welded to the bottom of the mating protrusion 43. In addition, a mating through hole 45 is opened on the sealing strip 42, and an installation rod 47 is welded to the sealing strip 42. The installation rod 47 is inserted into the support through hole 2. In section 7, a connecting spring 48 is sleeved on the mounting rod 47. The two ends of the connecting spring 48 are welded and fixed to the sealing strip 42 and the supporting protrusion 26, respectively. A movable connecting block 49 is also movably installed on the sealing strip 42. A first support rod 491 is welded and fixed on the movable connecting block 49 by welding. The first support rod 491 is inserted into the mating through hole 45. The movable connecting block 49 is movably installed on the sealing strip 42 by the mating through hole 45 and the first support rod 491. A second support rod 492 is also welded and fixed on the movable connecting block 49 by welding. A first mating connecting rod 46 is hinged on the movable connecting block 49. The other end of the first mating connecting rod 46 is hinged to the supporting protrusion 26.

[0039] A dustproof net 6 is installed on the server body 1. A movable support 62 is movably installed on the server body 1 to support the dustproof net 6. Specifically, an installation strip 61 is integrally formed and fixed at the lower end of the dustproof net 6. A positioning cavity 63 is provided on the movable support 62. The dustproof net 6 is installed on the movable support 62 through the cooperation of the positioning cavity 63 and the installation strip 61. When the fan 22 is not in operation, the dustproof net 6 is located at the opening of the air inlet slot 11 and blocks the air inlet slot 11. When the fan 22 is in operation, the dustproof net 6 is inserted into the air inlet slot 11. A matching plug 64 is symmetrically welded and fixed on the movable support 62 through a welding process. The matching plug 64 is inserted into the support guide hole 12. A connecting support block 65 is welded and fixed on the matching plug 64 through a welding process. The connecting support block 65 is located inside the server body 1 and has a connecting insertion hole 66.

[0040] The lightweight sealing plate 4 is connected to the movable support 62. The lightweight sealing plate 4 drives the movable support 62 to move, which in turn drives the dustproof net 6 to move. Specifically, when the cover 2 is fixedly installed on the server body 1, the connecting rod 44 on the lightweight sealing plate 4 is inserted into the connecting hole 66 on the connecting block 65. The connection between the lightweight sealing plate 4 and the movable support 62 is achieved through the cooperation of the connecting rod 44 and the connecting hole 66.

[0041] like Figure 3 , Figure 9 , Figure 10 and Figure 12 As shown, the movable heat dissipation sealing assembly includes: support strips 5, drive connecting plate 7, and channel baffle 74. There are two support strips 5, which are symmetrically installed on the mounting bracket 28 on the cover 2. Specifically, mounting mating holes 51 are symmetrically opened on the support strips 5, and mounting support rods 29 are inserted into the mounting mating holes 51. The support strips 5 are movably installed on the mounting bracket 28 by the mating of the mounting support rods 29 and the mounting mating holes 51. Support columns 52 are also symmetrically welded and fixed on the support strips 5 by welding process. In addition, a mating vertical strip 53 is welded and fixed to the upper end of the support strips 5 by welding process. An extension connecting plate 54 is welded and fixed to the mating vertical strip 53 by welding process. The extension connecting plate 54 is provided with support connecting holes 55 and connecting grooves 56.

[0042] The drive plate 7 is connected to the support strip 5. The support strip 5 drives the drive plate 7 to move. Specifically, a limiting hole 71 is opened on the drive plate 7, and a support rod 16 is inserted into the limiting hole 71. A connecting frame 72 is welded and fixed on the drive plate 7 by welding process. When the cover 2 is fixedly installed on the server body 1, the connecting frame 72 cooperates with the connecting groove 56. The connection between the drive plate 7 and the support strip 5 is realized through the cooperation of the two.

[0043] The channel baffle 74 is movably connected to the drive connecting plate 7. The drive connecting plate 7 drives the channel baffle 74 to move. Specifically, a second mating connecting rod 73 is hinged to the drive connecting plate 7. A magnet 75 is embedded in the channel baffle 74. A support plate frame 76 is welded to the channel baffle 74. The support plate frame 76 is hinged to the other end of the second mating connecting rod 73. The second mating connecting rod 73 enables the movable connection between the drive connecting plate 7 and the channel baffle 74. A movable connecting rod 77 is also welded to the support plate frame 76. The movable connecting rod 77 is inserted into the mounting guide hole 15.

[0044] The support strip 5 is movably connected to the lightweight sealing plate 4. The lightweight sealing plate 4 drives the support strip 5 to move. Specifically, the second support rod 492 is inserted into the support connecting hole 55 on the extension connecting plate 54. The movable connection between the lightweight sealing plate 4 and the support strip 5 is achieved through the cooperation between the second support rod 492 and the support connecting hole 55, and the second support rod 492 can move along the support connecting hole 55.

[0045] When the fan 22 is not in operation, the heat dissipation channel 14 is closed by the channel baffle 74. That is, when a heat dissipation channel 14 is provided with two channel baffles 74, and the channel baffle 74 at one heat dissipation channel 14 closes together, the magnets 75 on the channel baffles 74 attract each other to ensure the stability of the channel baffles 74.

[0046] like Figure 5 , Figure 7 , Figure 8 and Figure 13 As shown, the secondary air filtration assembly includes: a sealing mask 3 and a filter cartridge 8. The sealing mask 3 is fixedly installed on the sealing cover 21 by bolts, and an air supply pipe 31 is symmetrically welded and fixed on the sealing mask 3 by welding process. An air supply port 32 is opened below the air supply pipe 31, and two support bosses 33 are welded and fixed on the air supply pipe 31 by welding process. Support insertion holes 34 are opened on the support bosses 33, and a guide frame 35 is welded and fixed on the support bosses 33 away from the sealing mask 3 by welding process. A guide channel 36 is opened on the guide frame 35.

[0047] The filter cartridge 8 is inserted into the air supply duct 31, and the air is filtered a second time through the filter cartridge 8. The filter cartridge 8 is locked by the support strip 5. Specifically, a cover 81 is welded to one end of the filter cartridge 8. The cover 81 is fitted onto the air supply duct 31, and a connecting guide plate 82 is welded to the cover 81. The connecting guide plate 82 is inserted into the guide channel 36, and a locking hole 83 is opened on the connecting guide plate 82. The locking hole 83 is aligned with the support insertion hole 34. When the support strip 5 fixes the filter cartridge 8, the support column 52 is inserted into the locking hole 83. The filter cartridge 8 is locked by the cooperation between the support column 52 and the locking hole 83. At this time, the support column 52 is also inserted into the support insertion hole 34. The cooperation between the support column 52 and the support insertion hole 34 further supports the air supply duct 31 to ensure its stability during operation.

[0048] like Figure 14As shown, the server heat dissipation management system also includes a control module, a communication module, a temperature detection module, and a drive module. The temperature detection module detects the internal temperature of the server body 1 and feeds back the detection results to the control module through the communication module. When the internal temperature of the server body 1 reaches the heat dissipation requirement, the control module controls the fan 22 to work through the drive module to dissipate heat from the server.

[0049] A control method for a heat dissipation management system includes the following steps: Step 1: Temperature detection: The temperature of the server body 1 is detected by the temperature detection module. When the temperature is abnormal, the fan 22 will work to dissipate heat. Step 2: Locking the dustproof net 6: When the fan 22 is working, the wind force drives the lightweight sealing plate 4 to move, which in turn drives the dustproof net 6 to move, thereby locking the dustproof net 6 and ensuring its stability when filtering air. Step 3: Opening the heat exhaust channel 14: The lightweight sealing plate 4 moves the support strip 5, which in turn moves the drive plate 7 under the action of the support strip 5, so that the heat exhaust channel 14 is in the open state to exhaust heat.

[0050] When installing the cover 2, it is positioned on the server body 1 and then fixed with screws. At this time, the connecting rod 44 is inserted into the connecting hole 66, and the connecting groove 56 cooperates with the connecting frame 72.

[0051] When the fan 22 is working, the rotation of the fan 22, under the influence of negative pressure and the flow of outside air, will cause the lightweight sealing plate 4 to move towards the fan 22, thereby removing the seal on the air inlet 24. This allows outside air to enter the air delivery pipe 23 from the air inlet 24. As the lightweight sealing plate 4 moves, it will also move the dustproof net 6 towards the air inlet slot 11 and make contact with the inner wall of the air inlet slot 11. In this way, the air inlet slot 11 and the dustproof net 6 can lock the dustproof net 6, ensuring its stability during operation.

[0052] As the lightweight sealing plate 4 moves, the distance between the sealing strip 42 and the supporting protrusion 26 decreases. Consequently, under the action of the first cooperating connecting rod 46, the movable connecting block 49 moves away from the sealing strip 42. This movable connecting block 49 then moves the supporting strip 5, allowing the supporting column 52 on the supporting strip 5 to pass through the locking hole 83 and be inserted into the supporting insertion hole 34. This locks the filter cartridge 8 while providing auxiliary support for the air supply pipe 31, ensuring its stability during operation. In addition, the sealing strip 42 always closes the moving channel 25.

[0053] When installing the filter cartridge 8, the connecting guide plate 82 is inserted into the guide channel 36 and guided by the guide channel 36. Under the action of the filter cartridge 8, the air entering the air supply duct 31 can be filtered a second time, making the air discharged from the air supply port 32 cleaner.

[0054] As the support strip 5 moves, it will drive the drive connecting plate 7 to move towards the side wall of the server body 1. In this way, under the action of the second cooperating connecting rod 73, the channel baffle 74 will move in opposite directions, so that the heat dissipation channel 14 is in the open state, thus dissipating the heat inside the server body 1.

[0055] When the fan 22 stops working, the lightweight sealing plate 4 is reset under the action of the connecting spring 48, which in turn drives the dust filter 6 and the channel baffle 74 to reset, so that the dust filter 6 is in the unlocked state, which is convenient for disassembly and cleaning. After disassembly, with the cooperation of the air delivery pipe 23 and the lightweight sealing plate 4, no impurities will enter the server body 1. After the channel baffle 74 is reset, it blocks the heat dissipation channel 14 to prevent external dust from entering the server body 1 through the heat dissipation channel 14. In addition, the filter cartridge 8 is also in the unlocked state at this time. After the cover 2 is removed, it can be quickly taken out for cleaning.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
