Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and in particular to a liquid cooling device and a server cabinet. Background Art

[0002] With the rapid development of cloud computing and artificial intelligence technologies, modern servers are becoming increasingly dense and power-intensive, leading to a dramatic increase in the heat generated by electronic components. Traditional air cooling is no longer sufficient for these high-power servers. Liquid cooling, due to its high thermal capacity, is becoming the mainstream cooling solution in data centers. However, existing liquid cooling systems generally utilize a fixed design that cannot accommodate the installation requirements of servers of varying sizes, severely limiting their versatility and deployment flexibility.

[0003] First, the fixed mounting structure makes the equipment incompatible with server cabinets of varying sizes. Data center upgrades and renovations require custom brackets or the installation of multiple liquid cooling units of varying sizes, significantly increasing deployment costs. Second, traditional cooling fans lack adequate dust protection, and dust accumulation significantly reduces airflow efficiency. Furthermore, the rigidly connected liquid cooling pipes limit the scalability of the cooling module, making it difficult to address uneven heat distribution within server clusters. These shortcomings collectively hinder the large-scale adoption of liquid cooling systems in high-density data centers.

[0004] Therefore, there is an urgent need for a liquid cooling device that can meet the stringent requirements of modern high-density data centers on the flexibility, reliability and energy efficiency of the cooling system. Summary of the Invention

[0005] The present invention provides a liquid cooling device and a server cabinet, which at least solve the problem in the related art that the fixed installation structure of the traditional liquid cooling device cannot be adapted to server cabinets of different specifications.

[0006] The present invention provides a liquid cooling device, characterized by comprising a housing, a mounting assembly, and a liquid cooling assembly. The mounting assembly is disposed on a first side of the housing and is adapted to connect to the inner wall of a server cabinet. The mounting assembly includes two symmetrically arranged adjustment mechanisms configured to move synchronously toward or away from each other within a mounting plane parallel to the first side, and a plurality of mounting members movably disposed on the two adjustment mechanisms, each of the plurality of mounting members being provided with mounting holes. The liquid cooling assembly is disposed on a second side of the housing, opposite the first side.

[0007] The present invention further provides a server cabinet, comprising a cabinet body, in which at least one server body is installed; and the liquid cooling device, which is installed in the cabinet body to dissipate heat from the server body.

[0008] The liquid cooling device provided by the present invention has an adaptive installation function and adopts a modular design to solve the adaptability problem of traditional liquid cooling devices. By arranging an installation assembly consisting of a symmetrical adjustment mechanism and a movable mounting part on the first side of the box, flexible adjustment of the installation position is achieved: the two adjustment mechanisms can move synchronously toward or away from each other within the installation plane, and cooperate with multiple movable mounting parts with mounting holes to enable the liquid cooling device to quickly adapt to server cabinets of different specifications; at the same time, the liquid cooling assembly is independently arranged on the second side of the box, which not only ensures the heat dissipation performance but also optimizes the overall layout. This design significantly improves the versatility and deployment efficiency of the device, effectively solves the installation difficulty problem caused by size mismatch of traditional fixed liquid cooling devices, and at the same time ensures installation stability and heat dissipation effect.

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0071] It should be noted that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and are therefore not to be construed as limiting the present invention. The terms "mounted," "connected," and "connected" should be broadly construed, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the conditions described and conditions similar to the conditions described, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by one of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°. "Equal" includes both absolute equality and approximate equality, where the acceptable deviation range for approximate equality may be, for example, that the difference between the two is less than or equal to 5% of either. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0072] Existing liquid cooling devices for servers generally use a fixed mounting hole design for installation adaptability. This rigid structure prevents the equipment from being flexibly adjusted to the size specifications of different server cabinets. When faced with the various cabinet models commonly found in data centers, it is often necessary to specifically design and manufacture liquid cooling devices of corresponding sizes for servers of different specifications. This not only increases deployment costs but also extends the equipment installation cycle, severely restricting the large-scale application of liquid cooling systems. Secondly, in terms of long-term operation and maintenance, the cooling fans of existing liquid cooling devices lack an effective self-cleaning mechanism and continuously absorb dust particles from the environment during operation. Dust accumulation causes the airflow channel to narrow, reducing the suction efficiency of the cooling fan, which in turn affects the cooling performance of the heat sink. This problem of deteriorating heat dissipation performance due to dust accumulation not only increases additional energy consumption but also causes local overheating of the server, seriously affecting the operational reliability and service life of the equipment.

[0073] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0074] Figure 1 A three-dimensional structural diagram of the first side of a liquid cooling device provided by an embodiment of the present invention; Figure 2 A three-dimensional structural diagram of the second side of the liquid cooling device provided in an embodiment of the present invention; Figure 3 A three-dimensional structural diagram of the installation assembly in an expanded state provided by an embodiment of the present invention; Figure 4 for Figure 3 An enlarged view of point A in the three-dimensional structure diagram shown.

[0075] An embodiment of the present invention provides a liquid cooling device, such as Figures 1 to 4 As shown, the system comprises a housing 1, a mounting assembly 2, and a liquid cooling assembly 3. The mounting assembly 2 is disposed on a first side of the housing 1 and is configured to connect to the inner wall of the server cabinet. The mounting assembly 2 comprises two symmetrically arranged adjustment mechanisms 21, configured to move synchronously toward or away from each other within a mounting plane parallel to the first side; and a plurality of mounting members 22, movably disposed on the two adjustment mechanisms 21, each of the plurality of mounting members 22 being provided with mounting holes 221. The liquid cooling assembly 3 is disposed on a second side of the housing 1, opposite the first side.

[0076] According to the above-mentioned setting method, the installation component 2 is located on the first side of the housing 1, and is composed of two symmetrically arranged adjustment mechanisms 21 and multiple installation parts 22, wherein the adjustment mechanism 21 adopts a synchronous transmission design, which can realize precise displacement adjustment toward or away from each other within the installation plane; the installation part 22 is movably arranged on the adjustment mechanism 21 and is provided with a standardized installation hole 221, which is convenient for connection with server cabinets of different specifications. Furthermore, the liquid cooling component 3 is independently arranged on the second side of the housing 1, forming a functional partition separated from the installation component 2. Through the coordinated cooperation of the adjustment mechanism 21 and the installation part 22, multi-dimensional flexible adjustment of the installation position is achieved, so that the liquid cooling device can quickly adapt to server cabinets of different sizes, which not only ensures the stability and reliability of the installation, but also significantly improves the versatility and deployment efficiency of the equipment, and effectively solves the installation difficulty problem caused by size mismatch of traditional fixed liquid cooling devices.

[0077] In an illustrative embodiment, Figure 3 As shown, the mounting assembly 2 further includes a synchronization mechanism 23, comprising a first gear 231 and two racks 232. The first gear 231 is rotatably disposed at the center of the first side; the two racks 232 are symmetrically arranged on either side of the first gear 231 and mesh with the first gear 231. The two racks 232 are respectively connected to the two adjustment mechanisms 21. The rotation of the first gear 231 synchronously drives the two racks 232 to move linearly toward or away from each other.

[0078] Specifically, a centrally symmetrical gear-rack transmission structure is adopted, in which the two racks 232 are centrally symmetrical with respect to the first gear 231. The rotation of the first gear 231 synchronously drives the racks 232 on both sides to make linear motions toward or away from each other, ensuring that the displacements of the adjustment mechanisms 21 connected on both sides remain precisely synchronized, making the expansion / contraction process of the installation component 2 smooth and reliable.

[0079] According to the above-mentioned setting method, not only the adjustment of the position of the mounting member 22 is achieved, but also the bilateral synchronous adjustment can be completed through single-sided control, which greatly simplifies the installation operation process and significantly shortens the equipment installation time. At the same time, it ensures the balanced force during the installation process and significantly improves the stability and reliability of the installation structure.

[0080] In an alternative embodiment, the synchronization mechanism 23 may adopt a screw-nut transmission scheme, specifically including: a bidirectional screw, rotatably arranged at the center position of the first side of the box body 1 along a first direction, and having thread segments with opposite rotation directions processed at both ends thereof; two movable nuts, respectively threadedly connected to the thread segments at both ends of the bidirectional screw; two connecting rods, respectively connecting the two movable nuts with the corresponding adjustment mechanism 21; wherein, when the bidirectional screw rotates, the two movable nuts move synchronously in opposite directions along the axial direction of the screw, and then drive the adjustment mechanisms 21 on both sides 20 through the two connecting rods to achieve synchronous displacement toward or away from each other.

[0081] In an illustrative embodiment, Figure 4 FIG. 2 shows a partial enlarged view of one end of the adjustment mechanism 21. The adjustment mechanism 21 includes a movable plate 211, a positioning rod 212, two adjustment plates 213, and two adjustment blocks 214. The movable plate 211 is slidably disposed in the movable groove 11 on the first side of the housing 1 via the positioning rod 212. The movable plate 211 is symmetrically provided with two adjustment grooves 2111. The two adjustment plates 213 are slidably disposed in the two adjustment grooves 2111 via the adjustment blocks 214, respectively. A plurality of mounting members 22 are spaced apart between the two adjustment plates 213. The movable groove 11 extends along a first direction, and the two adjustment grooves 2111 extend along a second direction perpendicular to the first direction.

[0082] Furthermore, the first direction may be the width direction or the length direction of the box body 1 .

[0083] like Figure 3 As shown, the movable grooves 11 are symmetrically arranged on both sides of the first side of the box body 1 along the length direction of the box body 1 and are configured to extend along the width direction. Two positioning rods 212 are provided, and one end is connected to one side of a movable plate 211, and the other end is slidably arranged in the movable groove 11.

[0084] According to an embodiment of the present invention, Figure 3 and Figure 4 As shown, a pair of movable grooves 11 are symmetrically provided on the first side of the housing 1, and the two movable grooves 11 extend horizontally along the width direction of the housing 1. The movable plate 211 is slidably connected to the movable grooves 11 via positioning rods 212. The specific structure includes: two positioning rods 212, each vertically fixed to the two ends of the movable plate 211; the ends of the positioning rods 212 are provided with sliding portions, which cooperate with the guide rail structure of the movable groove 11; the guide rail structure of the movable groove 11 adopts a T-slot design, which forms a precise fit with the sliding portion of the positioning rods 212, ensuring that the movable plate 211 slides smoothly along the width direction of the housing 1. This symmetrical sliding connection structure not only ensures stability during the adjustment process, but also achieves precise control of the installation position.

[0085] In detail, the moving trajectories of the movable plate 211 and the adjusting plate 213 are configured to be orthogonally distributed, and two-dimensional precise adjustment of the installation position is achieved through the movable groove 11 in the first direction and the adjusting groove 2111 in the second direction, so that the installation component 2 can flexibly adapt to the installation space requirements of different server cabinets; the linear sliding of the movable plate 211 on the box body 1 is combined with the linear sliding of the adjusting plate 213 on the movable plate 211 to form a cross-shaped orthogonal adjustment path, which expands the adjustment range of the installation position. This modular design allows the position of the mounting part 22 to be independently adjusted in the horizontal and vertical directions, and can accurately match various installation holes of the server cabinet, greatly improving the installation efficiency and adaptability, and solving the problem that the traditional fixed installation structure is difficult to adapt to servers of different specifications.

[0086] In an illustrative embodiment, Figure 4 As shown, the ends of the two adjustment plates 213 are rotatably connected to the corresponding adjustment blocks 214, so that the adjustment plates 213 can rotate around the rotation axis within the installation plane.

[0087] Specifically, the rotatable connection structure between the adjustment plate 213 and the adjustment block 214 enables the mounting member 22 to adjust the mounting hole more freely within the installation plane, significantly improving the two-dimensional adjustment capability of the mounting assembly, and enabling the mounting member 22 to fine-tune the angle within the installation plane. Combined with the original two-dimensional linear displacement adjustment function, precise control of the position and angle within the installation plane is achieved; at the same time, the rotating connection structure is simple and reliable, which not only ensures the convenience of the adjustment operation, but also can stably maintain the adjusted angular position, significantly improving the installation adaptability and adjustment efficiency of the liquid cooling device within the two-dimensional plane.

[0088] In an illustrative embodiment, Figure 3 and Figure 4As shown, the movable plate 211 is also symmetrically provided with two limiting grooves 2112, which are respectively connected to the two adjustment grooves 2111; the adjustment block 214 is threadedly connected to the external limiting bolt 216 through the limiting groove 2112, and the limiting bolt 216 has a locking state that abuts against the outer wall of the movable plate 211 to lock the adjustment block 214.

[0089] Specifically, the adjacent side walls of the movable plate 211 are provided with interconnected adjustment slots 2111 and stop slots 2112, forming an L-shaped guide channel. The adjustment block 214 is slidably disposed within this L-shaped channel, capable of both moving along the adjustment slots 2111 to adjust the position of the adjustment plate 213 and threadedly connecting with a stop bolt 216 via the stop slots 2112. After position adjustment is complete, the stop bolt 216 is tightened until its end abuts the outer wall of the movable plate 211, locking the adjustment block 214.

[0090] The abutment locking method between the limit bolt 216 and the outer wall of the movable plate 211 is not only simple and reliable in structure, but also convenient for the operator to quickly confirm the locking state, while maintaining smoothness during adjustment, ensuring that the installation components will not be displaced during long-term use, and significantly improving the structural stability and safety of the liquid cooling device after installation.

[0091] In an illustrative embodiment, Figure 4 As shown, a plurality of mounting members 22 are slidably disposed in the sliding slots 2131 of the adjustment plate 213 .

[0092] Specifically, the mounting member 22 forms a sliding connection structure with the adjustment plate 213 through the sliding groove 2131, so that the mounting member 22 can be linearly adjusted in the extension direction of the sliding groove 2131. Combined with the rotation adjustment function of the adjustment plate 213, precise control of multiple degrees of freedom within the installation plane is achieved; the liquid cooling device can more flexibly adapt to the changing requirements of the server cabinet installation hole spacing, effectively solving the adaptability problem of the traditional fixed-spacing installation method within the installation plane; at the same time, the guiding structure of the sliding groove 2131 ensures the smoothness of the adjustment process, significantly improving the position adjustment capability and installation efficiency of the liquid cooling device within the installation plane.

[0093] Figure 5 for Figure 3 The enlarged view at point B in the three-dimensional structural diagram shows a partial enlarged view of the end of the adjustment plate 213 of the adjustment mechanism 21 away from the adjustment block 214 in the initial state where no rotation occurs.

[0094] In an illustrative embodiment, Figure 5 As shown, a fixing mechanism 215 is provided at the end of the adjustment plate 213 away from the adjustment block 214 , and is configured to cooperate with a fixing hole preset on the movable plate 211 to fix the adjustment plate 213 .

[0095] In detail, the fixing mechanism 215 includes a fastening bolt, which is rotatably provided on the adjustment plate 213 through a thread, and extends out of the adjustment plate 213 by rotation, and cooperates with the fixing hole on the movable plate 211 to limit the rotation of the adjustment plate 213.

[0096] In an optional embodiment, the fixing mechanism 215 may further include a pin, which is retractably arranged in the adjustment plate 213 through a spring and can automatically be inserted into a fixing hole on the movable plate 211 for fixation.

[0097] Figure 6 A three-dimensional structural diagram of a liquid cooling assembly provided in an embodiment of the present invention.

[0098] In an illustrative embodiment, Figure 2 and Figure 6 As shown, the liquid cooling assembly 3 includes a fixed cold plate unit 31, an extended cold plate unit 32, a refrigeration box 33, a first circulation pipeline 34, and a second circulation pipeline 35. The fixed cold plate unit 31 is fixed in the housing 1; the extended cold plate unit 32 is slidably disposed in the housing 1, and has a storage state within the housing 1 and an extended state in which it at least partially extends from the side wall of the housing 1. The refrigeration box 33 is disposed in the housing 1 and is connected to the fixed cold plate unit 31 via the first circulation pipeline 34 and to the extended cold plate unit 32 via the second circulation pipeline 35.

[0099] According to the above-mentioned setting method, a combination structure of a fixed cold plate unit 31 and a slidable extended cold plate unit 32 is adopted, so that the liquid cooling component 3 can flexibly adjust the heat dissipation area according to the heat dissipation requirements of the server; the refrigeration box 33 is connected to the fixed cold plate unit 31 and the extended cold plate unit 32 through an independent first circulation pipeline 34 and a second circulation pipeline 35, respectively, which not only ensures the basic heat dissipation performance, but also realizes the ready-to-use nature of the extended cold plate unit 32; this design effectively solves the problem that the traditional liquid cooling device has a fixed heat dissipation area and cannot adapt to dynamic heat loads, and significantly improves the adaptability and reliability of the liquid cooling component 3 under different workloads.

[0100] In an illustrative embodiment, Figure 6 As shown, the first circulation pipeline 34 includes a water inlet pipe 341 and a water outlet pipe 342. The water inlet pipe 341 is connected between the liquid outlet of the refrigeration box 33 and the liquid inlet end of the fixed cold plate unit 31, and the water outlet pipe 342 is connected between the liquid outlet end of the fixed cold plate unit 31 and the liquid return end of the refrigeration box 33, forming a circulating cold mass circuit.

[0101] Further, such as Figure 6 As shown, the liquid cooling assembly further includes a fluid pump 37 , which is disposed on the water inlet pipe 341 outside the refrigeration box 33 to drive the internal refrigerant to circulate.

[0102] In an illustrative embodiment, Figure 6 As shown, the second circulation pipeline 35 includes a water inlet hose 351 and a water outlet hose 352. The water inlet hose 351 can be bendably connected between the liquid inlet end of the extended cold plate unit 32 and the refrigeration box 33; and the water outlet hose 352 can be bendably connected between the liquid outlet end of the extended cold plate unit 32 and the refrigeration box 33; wherein the reserved length of the water inlet hose 351 and the water outlet hose 352 is not less than the maximum extension stroke of the extended cold plate unit 32 to keep the pipeline connected in the extended state.

[0103] In detail, the flexible pipeline design realizes the barrier-free extension and retraction of the extended cold plate unit 32. The water inlet hose 351 and the water outlet hose 352 are made of bendable flexible materials and redundant length design, so that the pipeline is always kept unobstructed throughout the entire extension stroke of the extended cold plate unit 32, ensuring uninterrupted circulation of the coolant; this design overcomes the problem of using rigid pipelines to limit the range of movement, so that the extended cold plate unit 32 can freely adjust the extension length according to the heat dissipation requirements, and the heat dissipation area is significantly increased. At the same time, the flexible connection effectively avoids stress concentration in the pipeline, thereby improving the reliability of the system.

[0104] In an illustrative embodiment, the water inlet hose 351 and the water outlet hose 352 adopt a special bellows structure to ensure durability and flexibility under repeated expansion and contraction conditions.

[0105] In an alternative embodiment, the water inlet hose 351 is flexibly connected between the liquid inlet end of the extended cold plate unit 32 and the liquid inlet end of the fixed cold plate unit 31; and the water outlet hose 352 is flexibly connected between the liquid outlet end of the extended cold plate unit 32 and the liquid outlet end of the fixed cold plate unit 31. This allows the extended cold plate unit 32 to circulate through the fixed cold plate unit 31.

[0106] In an exemplary embodiment, the extended cold plate unit 32 is disposed outside the fixed cold plate 31 and moves along a guide rail disposed in the box body 1 through a connecting frame.

[0107] In an illustrative embodiment, Figure 6 As shown, the fixed cold plate unit 31 and the extended cold plate unit 32 are each composed of coiled cold pipes. Specifically, each comprises multiple parallel U-shaped cold pipes made of a high-thermal-conductivity copper alloy, interconnected by a header to form a serpentine cooling channel. Furthermore, the inner wall of each cold pipe is equipped with turbulence-enhancing structures, such as spiral guide vanes or micro-protrusion arrays, which create turbulent flow in the coolant and improve the heat transfer coefficient.

[0108] In an illustrative embodiment, Figure 2As shown, the liquid cooling assembly 3 further includes a limiting bolt 36 , which is telescopically disposed on the side wall of the second side of the box body 1 ; wherein, when the limiting bolt 36 is extended, it abuts against the extended cold plate unit 32 .

[0109] Specifically, the limit bolt 36 adopts a retractable structure and is set on the side wall of the box body 1. The extended position of the extended cold plate unit 32 can be firmly fixed by simple mechanical locking to prevent it from being displaced under vibration or accidental collision. It is easy to operate and significantly improves the reliability and safety of the liquid cooling system under different working conditions.

[0110] Figure 7 for Figure 3 Schematic diagram of the internal structure of the liquid cooling device in the state shown.

[0111] In an illustrative embodiment, Figures 1 to 3 and Figure 7 As shown, it also includes a heat dissipation assembly 4, including at least one heat dissipation unit 41, which is arranged in the installation groove 12 on the first side of the box body 1 through a heat dissipation frame 42 and is configured to provide heat dissipation airflow into the box body 1; and a dustproof net 43, which is arranged on the outside of the heat dissipation frame 42.

[0112] Specifically, the heat dissipation unit 41 is fixed in the mounting groove 12 of the box body 1 through the heat dissipation frame 42, forming a directional airflow channel, so that the heat dissipation airflow effectively enters the box body 1, and at the same time the setting of the dustproof net 43 effectively blocks the entry of dust and other particles; this setting method not only ensures the efficient heat dissipation performance of the liquid cooling system, but also effectively solves the performance degradation problem caused by dust accumulation in traditional heat dissipation devices, so that the system can maintain stable heat dissipation efficiency during long-term operation.

[0113] In an exemplary embodiment, a plurality of heat dissipation units 41 are provided at intervals, as shown in detail. Figure 1 and Figure 7 As shown, two heat dissipation units 41 are provided and symmetrically distributed along the central axis of the box body 1 .

[0114] In an illustrative embodiment, Figure 1 As shown, it also includes a cleaning component 5, including: a cleaning scraper 51 and a rotating drive mechanism 52, the cleaning scraper 51 is arranged on the housing 1, and is configured to contact the dustproof net 43; the rotating drive mechanism 52 is arranged in the housing 1; wherein, the heat dissipation frame 42 is configured to be rotatably arranged in the mounting groove 12, and the dustproof net 43 is rotated relative to the cleaning scraper 51 by the driving of the rotating drive mechanism 52.

[0115] In detail, when the rotating drive mechanism 52 drives the heat dissipation frame 42 to rotate, the fixed cleaning scraper 51 and the dustproof net 43 produce relative movement, which can effectively remove the dust accumulated on the surface of the dustproof net 43; this self-cleaning design can maintain the good ventilation performance of the dustproof net 43, and avoid the performance degradation problem of the traditional heat dissipation system caused by dust accumulation.

[0119] In an illustrative embodiment, Figures 7 to 9 As shown, the rotation drive mechanism 52 includes an outer gear ring 521, a drive gear 522, and a drive motor 523.

[0122] In an illustrative embodiment, Figure 10 and Figure 11As shown, the cleaning assembly 5 also includes a dust collection unit 53, including a dust collection pipe 531, a dust collection box 532, a connecting pipe 533, and a negative pressure fan 534. The dust collection pipe 531 is installed on the cleaning scraper 51, and the wall of the dust collection pipe 531 is provided with evenly distributed dust collection holes; the dust collection box 532 is installed in the box body 1; the connecting pipe 533 connects the dust collection pipe 531 and the dust collection box 532; and the negative pressure fan 534 is installed on the top of the dust collection box 532. When the negative pressure fan 534 is in operation, it forms a negative pressure airflow within the dust collection unit 53 and collects dust generated by cleaning through the dust collection holes.

[0123] In detail, when the negative pressure fan 534 is working, a stable negative pressure airflow is formed in the dust collecting unit 53, and the dust peeled off by the cleaning scraper 51 is promptly sucked and collected through the dust suction holes evenly distributed on the dust suction pipe 531; this design effectively avoids the secondary dust problem caused by traditional cleaning methods and keeps the interior of the box 1 clean; the dust collecting box 532 can also be configured with a non-detachable structure for regular cleaning, and the flexible connection method of the connecting pipe 533 ensures the sealing of the system and improves the convenience of maintenance, which significantly improves the efficiency and environmental friendliness of the cleaning operation.

[0124] According to an embodiment of the present invention, Figure 11 As shown, a plurality of tooth brushes 511 are provided at intervals in the extending direction of the cleaning blade 51 .

[0125] According to an embodiment of the present invention, Figure 11 As shown, dust collection tubes 531 are symmetrically arranged on either side of the cleaning blade 51. The two sets of dust collection tubes 531 are arranged in mirror-image symmetry about the central axis of the cleaning blade 51. Each set of dust collection tubes 531 has multiple wedge-shaped absorption grooves evenly distributed along the axial direction of the tube wall, with the openings of the absorption grooves facing the cleaning surface of the cleaning blade 51. The dust collection tubes 531 are made of corrosion-resistant aluminum alloy, and the inner walls are polished to reduce flow resistance. The two sets of dust collection tubes 531 are connected to the main connecting pipe 533 via a Y-shaped diverter joint to ensure uniform airflow distribution. This symmetrical dust collection structure allows dust to be simultaneously collected from both sides during the cleaning process, preventing secondary dusting. The wedge-shaped absorption groove design also improves dust capture efficiency.

[0126] An embodiment of the present invention further provides a server cabinet, comprising a cabinet body, in which at least one server body is installed; and a liquid cooling device installed in the cabinet body to dissipate heat from the server body.

[0127] According to an embodiment of the present invention, the installation and use process of the liquid cooling device is as follows:

[0128] First, position the box 1 in the server cabinet, and move the rack 232 by pulling the movable plate 211 on one side, and realize symmetrical adjustment of the movable plates 211 on both sides under the synchronous action of the first gear 231; after adjustment, loosen the fixing mechanism 215 to release the limit of the adjustment plate 213, rotate the adjustment plate 213 to a suitable angle, and then slide the mounting part 22 to align the mounting hole 221 with the server mounting hole position, and finally tighten the bolts to complete the installation; the position of the adjustment plate 213 can be further adjusted by loosening the limit bolt 216 to enhance adaptability.

[0129] During the deployment phase of the liquid cooling assembly 3, the limit bolt 36 is loosened to release the fixation of the extended cold plate unit 32, which is then slid out to contact the electronic components and then re-locked. A combined heat dissipation surface is formed by fixing the cold plate unit 31 and the extended cold plate unit 32; the fluid pump 37 is started to drive the coolant circulation, and the heat dissipation unit 41 is started to enhance the heat dissipation effect;

[0130] During the automatic cleaning and maintenance stage, when it is detected that the heat dissipation performance has declined, the drive motor 52 is started to drive the heat dissipation frame 42 to rotate through the engagement of the drive gear 522 and the outer gear ring 521, and at the same time, the cleaning scraper 51 removes dust from the outer dustproof net 43; the negative pressure fan 534 works to generate negative pressure in the dust box 532, and the dust is sucked into the dust box 532 through the absorption groove of the connecting pipe 533 and the dust suction pipe 531, completing automatic cleaning.

[0131] In summary, the liquid cooling device and server cabinet provided by the present invention, first, adopt a mounting assembly 2 that can be adjusted in both directions synchronously, and realize the precise displacement of the adjustment mechanism 21 on both sides through a gear-rack mechanism or a screw-nut mechanism, and cooperate with the rotatable adjustable mounting member 22, thereby solving the problem that the traditional fixed mounting structure cannot adapt to server cabinets of different specifications; secondly, an expandable liquid cooling assembly 3 is designed, and the dynamic adjustment of the heat dissipation area is realized through the sliding connection of the extended cold plate unit 32 and the flexible second circulation pipeline 35, thereby overcoming the limitation of the fixed heat dissipation capacity of the traditional liquid cooling device; thirdly, a self-cleaning heat dissipation assembly 4 is integrated, and the performance degradation problem caused by dust accumulation of the cooling fan is effectively solved through the cooperation of the rotating heat dissipation frame 42 and the cleaning scraper 51, combined with the negative pressure dust collection unit 53. These innovative designs significantly improve the installation adaptability, heat dissipation efficiency and maintenance convenience of the equipment while maintaining the compactness of the structure, providing a reliable solution for the heat dissipation needs of high-density data centers.
