Liquid cooling system splash guards, liquid cooling cabinets and servers

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on March 29, 2024, with application number 202410379841.1, and entitled “Liquid cooling system anti-splash device, liquid cooling cabinet and server”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The embodiments of the present application relate to the field of server liquid cooling technology, and more specifically, to a liquid cooling system splash prevention device, a liquid cooling cabinet, and a server. Background Art

[0004] Conventional air cooling systems used for data center servers and other computing equipment are no longer able to meet heat dissipation requirements. To ensure the stability and reliability of data center servers and improve the data center's power usage efficiency (PUE) indicator, some solutions currently use liquid cooling technology. Depending on whether the liquid coolant undergoes phase change, immersion liquid cooling can be divided into single-phase immersion liquid cooling and phase change immersion liquid cooling. The distribution of cooling capacity to each server node is controlled by a liquid coolant distribution unit (CDU), and most methods establish liquid communication with each server node through a diverter.

[0005] In the existing system, the liquid cooling system includes a liquid cooling pipeline installed in the liquid cooling cabinet of the data center, through which the coolant used to dissipate heat from the heat sources in the liquid cooling cabinet is circulated to dissipate heat and cool down the heat sources in the liquid cooling cabinet.

[0006] In liquid-cooled cabinets, a typical male-female joint assembly structure for liquid cooling pipes uses threaded hoses to connect the liquid cooling medium distribution unit and the manifold. This solution can improve operability to a certain extent when assembling within a small joint spacing. However, there is a problem with improper assembly and fixing, which affects the sealing of the joints. In particular, small air or liquid leaks are difficult to detect in time, which can easily lead to operational hazards of the equipment and cause liquid splashing, causing liquid to spray inside the cabinet, causing contamination and damage to servers.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] In order to solve the problem in the related art that liquid cooling pipe joints are easily damaged due to liquid leakage when docking, the embodiments of the present application provide a liquid cooling system splash prevention device, a liquid cooling cabinet and a server.

[0050] Example 1

[0051] A liquid cooling system splash prevention device as shown in Figures 1 to 10 includes a base 10 and a cover 20. The base 10 is movably arranged at the liquid cooling pipe joint 80. The base 10 has a cavity, and the cavity has a through hole for the liquid cooling pipe joint 80 to extend into the cavity; the cover 20 is movably arranged in the cavity and has a blocking position for blocking the liquid cooling pipe joint 80 and a avoidance position for avoiding the liquid cooling pipe joint 80. When the base 10 moves relative to the liquid cooling pipe joint 80, the cover 20 is switched from the blocking position to the avoidance position under the drive of the liquid cooling pipe joint 80.

[0052] In this embodiment, a blocking cover 20 is provided in the base 10. The blocking cover 20 can shield the liquid cooling pipe joint 80. The design of the inner cavity of the base 10 enables the base 10 to collect the overflowing liquid. Specifically, when the liquid cooling pipe joint 80 does not need to be docked, the blocking cover 20 is in the blocking position. At this time, the liquid cannot splash out from the liquid cooling pipe joint 80 due to the blocking of the blocking cover 20. Even if some liquid overflows, it can only splash onto the blocking cover 20 under the shielding of the blocking cover 20, and then flow into the cavity along the blocking cover 20. At this time, the cavity can be It plays the role of collecting liquid, preventing the liquid from further overflowing onto the device, and plays a protective role for the device; and when the joints need to be docked, the joint to be docked 90 can push the base 10 to move, so that the base 10 moves relative to the fixed liquid-cooling pipe joint 80. The movement of the base 10 causes direct or indirect interference between the cover 20 and the liquid-cooling pipe joint 80, thereby changing the state of the cover 20. The cover 20 switches to the avoidance position, thereby avoiding the liquid-cooling pipe joint 80, so that the joint to be docked 90 can be docked with the liquid-cooling pipe joint 80. The above-mentioned setting method enables the splash-proof device to realize the splash-proof and overflow collection functions of the liquid-cooling pipe joint 80 on the one hand, ensuring that the cooling liquid will not affect the device, and on the other hand, it does not affect the normal docking of the pipeline, so that the joints of the pipeline can be freely docked and separated.

[0053] The above-mentioned blocking position and avoidance position are more accurately described as the blocking and avoidance of the opening at one end of the liquid-cooling pipe joint 80 by the blocking cover 20, that is, when the side with a larger area of ​​the blocking cover 20 faces the opening of the liquid-cooling pipe joint 80, it is in the blocking position. At this time, the liquid sprayed from the opening will splash on the blocking cover 20, and when the side with a larger area of ​​the blocking cover 20 no longer faces the opening of the liquid-cooling pipe joint 80, it is in the avoidance position. At this time, the liquid-cooling pipe joint 80 and the joint to be docked 90 can be docked smoothly.

[0054] It should be noted that pipe docking generally requires at least two joints to be connected together by plugging or other means. Therefore, this embodiment uses the two pipes to be docked, namely the liquid cooling pipe joint 80 and the joint to be docked 90, as an example for explanation, as shown in Figures 1 and 2, where the liquid cooling pipe joint 80 is a relatively fixed joint, while the structure to be docked is a movable joint that operates the docking. That is, the liquid cooling pipe joint 80 is fixed and the structure to be docked moves toward the liquid cooling pipe joint 80 to achieve docking. Of course, the specific docking method in actual use may vary, but it is only necessary to set the liquid cooling system splash guard of this embodiment at the joint of the pipe. Whether the joint is fixed or movable does not affect the functioning of the device.

[0055] As shown in Figures 3 to 6, in this embodiment, the liquid cooling system splash prevention device further includes a movable bracket 30, which is disposed within the cavity. The movable bracket 30 has a connection hole 31 for the liquid cooling pipe joint 80 to pass through. Thus, the movable bracket 30 is essentially sleeved on the outside of the end of the liquid cooling pipe joint 80, and the blocking cover 20 is disposed at the opening of the connection hole 31, thereby enabling the blocking cover 20 to shield the opening of the liquid cooling pipe joint 80. Thus, when a docking joint is required, the base 10 moves relative to the liquid cooling pipe joint 80 under the action of an external force. At this time, the movement of the base 10 directly or indirectly drives the movable bracket 30 to move, causing the movable bracket 30 to push the blocking cover 20 to an avoidance position. It should be noted that due to the setting of the above-mentioned movable bracket 30, the end of the liquid cooling pipe joint 80 also has a movable bracket 30 in addition to the liquid cooling pipe itself. Therefore, when the cover 20 moves to the avoidance position, the component that directly contacts the cover 20 can be the movable bracket 30, or the liquid cooling pipe joint 80, or both can contact at the same time to push the cover 20.

[0056] The movable bracket 30 of this embodiment is movably disposed within the base 10, and the movable bracket 30 moves relative to the base 10 in the same manner as the base 10 moves relative to the liquid-cooling pipe joint 80. More specifically, both brackets are movably disposed along the axial direction of the liquid-cooling pipe joint 80. Thus, when the docking joint 90 abuts the base 10, the base 10 and the movable bracket 30 therein can move along the axial direction of the liquid-cooling pipe joint 80, thereby allowing the liquid-cooling pipe joint 80 to extend further into the base 10, or even extend from the other side of the base 10, thereby pushing the cover 20 to move, allowing the cover 20 to avoid the liquid-cooling pipe joint 80. Of course, the movable bracket 30 can also be fixedly disposed within the base 10 as needed. In this case, the movable bracket 30 and the base 10 can essentially be an integral component.

[0057] In this embodiment, the liquid cooling system splash prevention device also includes an elastic member 40, which can be a spring or other component. The elastic member 40 is disposed between the base 10, the movable bracket 30, and the liquid cooling component having the liquid cooling pipe joint 80, and provides the base 10 and the movable bracket 30 with an elastic force to cause the cover 20 to switch to the shielding position. In this way, the base 10 and the movable bracket 30 have a tendency to move away from the liquid cooling component, that is, toward the direction in which the liquid cooling pipe joint 80 exits the cavity, which also causes the shift lever to always have a tendency to move away from the liquid cooling pipe joint 80. Therefore, when there is no external force pushing on the base 10, the cover 20 can automatically eliminate the force between the cover 20 and the liquid cooling pipe joint 80, thereby allowing the cover 20 to return to the shielding position that blocks the liquid cooling pipe joint 80. The liquid cooling component in this embodiment is specifically a diverter. The male end of the liquid cooling pipe on the diverter is the liquid cooling pipe joint 80, and the other component connected to the diverter is a node server. The female end of the liquid cooling pipe of the node server is the connector 90 to be connected.

[0058] Since the base 10, movable bracket 30, and liquid cooling component of this embodiment are all arranged in a movable manner, the elastic member 40 of this embodiment spans the base 10, movable bracket 30, and liquid cooling component. Specifically, as shown in Figures 3 and 9, the elastic member 40 includes a first elastic portion 41 and a second elastic portion 42. The first elastic portion 41 is located between the base 10 and the movable bracket 30, and the second elastic portion 42 is located between the movable bracket 30 and the liquid cooling component. In this way, the first elastic portion 41 serves to adjust the positional relationship between the base 10 and the movable bracket 30, while the second elastic portion 42 serves to adjust the positional relationship between the movable bracket 30 and the liquid cooling component, thereby achieving automatic position adjustment and automatic reset of the base 10, movable bracket 30, and liquid cooling component.

[0059] The elastic member 40 of this embodiment is an integral component, that is, the first elastic portion 41 and the second elastic portion 42 are connected in sequence. Accordingly, a through hole is provided on the movable bracket 30, and the connection between the first elastic portion 41 and the second elastic portion 42 is located in the through hole. In this way, on the one hand, the elastic member 40 as a whole can ensure the consistency of its structure, and on the other hand, the two elastic portions of the elastic member 40 can respectively cooperate with the corresponding components to realize automatic adjustment of the positions of the base 10, the movable bracket 30, and the liquid cooling component.

[0060] To improve the reliability of the fit between the elastic member 40 and the movable bracket 30, the elastic member 40 of this embodiment further includes an intermediate connecting portion 43, which is disposed between the first elastic portion 41 and the second elastic portion 42. The intermediate connecting portion 43 can be annular, forming a gasket-like structure. This facilitates the connection between the first elastic portion 41 and the second elastic portion 42 via the intermediate connecting portion 43, while also facilitating the insertion and fit of other structures such as guide posts. The intermediate connecting portion 43 primarily functions to fit the movable bracket 30. Specifically, the intermediate connecting portion 43 is located within the through-hole, and its size is substantially the same as that of the through-hole, allowing the intermediate connecting portion 43 to be locked into the through-hole. This achieves a coordinated fit between the elastic member 40 and the movable bracket 30. When the elastic member 40 is compressed, its overall length decreases, and the position of the intermediate connecting portion 43 also changes, thereby enabling the movable bracket 30 to change its axial position under the action of the elastic member 40.

[0061] In this embodiment, the intermediate connecting portion 43 has a certain thickness, which refers to the thickness along the axial direction of the elastic member 40. The thickness is preferably 0.5-2 mm, and more preferably 1 mm. The intermediate connecting portion 43 and the two elastic members can be welded together. This allows the diameter of the movable bracket 30 to be more effectively controlled, and prevents deformation of the elastic member 40 under external forces, which would affect the spring's limiting function.

[0062] In this embodiment, the first elastic portion 41 and the second elastic portion 42 are not identical. More specifically, the diameters of the first elastic portion 41 and the second elastic portion 42 are different. The diameter of the first elastic portion 41 is larger than that of the second elastic portion 42. Thus, the connection between the two, i.e., the location of the intermediate connecting portion 43, is where the diameter changes. This location, in conjunction with the movable bracket 30, can control the movable bracket 30 to move synchronously with the compression and extension of the elastic member 40, thereby controlling the movement of the movable bracket 30. Furthermore, it can control the range of motion of the movable bracket 30, thereby acting as a position limiter. Of course, the elastic member 40 can also be configured with two elastic portions of equal diameter. In this case, a structure such as a snap fit can be provided at the intermediate connecting portion 43 to achieve engagement with the movable bracket 30, thereby ensuring reliable engagement between the elastic member 40 and the movable bracket 30.

[0063] Preferably, in this embodiment, the diameter of the first elastic portion 41 is 7.5-10 mm, the diameter of the second elastic portion 42 is 5-6.5 mm, and the diameter of the connection hole 31 is 6.5-7.5 mm. More preferably, the diameter of the first elastic portion 41 is 8 mm, the diameter of the second elastic portion 42 is 6 mm, and the diameter of the connection hole 31 is 7 mm. Of course, the specific values ​​can be adjusted accordingly based on factors such as the size of other components of the device.

[0064] In this embodiment, the liquid cooling system splash prevention device further includes a mounting base 50. The mounting base 50 may have a mounting hole, and bolts may be inserted through the mounting hole and the liquid cooling component to achieve a reliable connection between the mounting base 50 and the liquid cooling component. Furthermore, in this embodiment, a connecting hook is provided on the mounting base 50. Accordingly, the end of the second elastic portion 42 is provided with an annular structure that can be hooked onto the connecting hook, thereby connecting the second elastic portion 42 to the mounting base 50. In this way, the second elastic portion 42 can be connected to the liquid cooling component via the mounting base 50. Of course, the connection between the second elastic portion 42 and the liquid cooling component is not limited to the above-described arrangement of this embodiment. Alternatively, the mounting base 50 may be omitted and the second elastic portion 42 may be directly connected to the liquid cooling component. Alternatively, the mounting base 50 may adopt other structural forms, as long as it can serve as an intermediate component connecting the second elastic portion 42 to the liquid cooling component. For example, a snap-fit ​​structure may be provided on the mounting base 50 to secure the second elastic portion 42 to the mounting base 50.

[0065] In this embodiment, the liquid cooling system splash prevention device further includes a guide structure, which can be a guide post or the like. The guide structure is connected to the base 10 and / or the movable bracket 30. The extension direction of the guide structure is parallel to the movement direction of the base 10 and the movement direction of the movable bracket 30. The elastic member 40 is disposed on the outside of the guide structure, thereby ensuring that both the base 10 and the movable bracket 30 can only move along the axial direction of the liquid cooling pipe joint 80, thereby ensuring the stability of movement. In addition to the above, a guide member such as a guide post on the liquid cooling component can also be utilized. That is, the second elastic portion 42 can be disposed on the guide post on the liquid cooling structure to achieve a guiding effect.

[0066] In this embodiment, the liquid cooling system splash guard device further includes a buffer assembly 60, which is disposed on the side of the base 10 facing the docking joint 90. The main function of the buffer assembly 60 is to buffer the transmission between the docking joint 90 and the base 10. That is, when the docking joint 90 approaches the base 10, the components of the docking joint 90 will first contact the buffer assembly 60, and then drive the base 10 to move through the buffer assembly 60, or after contacting the buffer assembly 60 for a certain distance, contact the base 10 again, thereby avoiding hard collisions. At the same time, because the buffer assembly 60 is movable relative to the base 10, after the docking joint 90 has driven the base 10 to move, as the docking joint 90 further pushes, the buffer assembly 60 can further extend into the base 10 until most or even all of the buffer assembly 60 enters the base 10. The buffer assembly 60 can reduce the additional space occupied by the buffer assembly 60, thus making the distance between the two sides of the liquid cooling system splash guard device along the docking direction of the joints smaller, thereby meeting the requirements of use in narrow spaces.

[0067] Specifically, the buffer assembly 60 of this embodiment includes a buffer member 61 and a buffer elastic member 62. The buffer member 61 is movably provided on the base 10, and one end of the buffer member 61 protrudes from the surface of the base 10. The movement direction of the buffer member 61 relative to the base 10 is the same as the movement direction of the base 10. The buffer elastic member 62 can be a spring, one end of which abuts the buffer member 61 and the other end abuts the base 10. The buffer elastic member 62 provides elastic force for the buffer member 61 to move in the direction of extending out of the base 10. In this way, when the docking joint 90 approaches the base 10, it will first abut the buffer member 61 and push the buffer member 61 to move in the direction of approaching the liquid-cooling component. At this time, the buffer elastic member 62 will be compressed, and the elastic force of the buffer elastic member 62 will be transmitted to the base 10, thereby driving the base 10 to move. The base 10 then drives the movable bracket 30 to move through the elastic member 40, thereby switching the position of the cover 20. The above-mentioned setting of the buffer assembly 60 avoids the situation where the components collide with each other, thereby improving the service life of the components. Of course, in addition to the above-mentioned setting method, the buffer component 60 can also adopt other structural forms, such as using a rubber part directly set on the side of the base 10 facing the joint to be docked 90, etc., as long as it can play a buffering role in the contact between the joint to be docked 90 and the base 10.

[0068] As shown in Figure 10, the buffer member 61 of this embodiment adopts a rod-shaped structure, one end of which is a plane. This end extends out of the base 10 for cooperating with the joint 90 to be docked, and the other end is provided with a guide column, and the buffer elastic member 62 is sleeved on the guide column. At the same time, an axially extending extension section is also provided at the end provided with the guide column. The length of the extension section is longer than the length of the guide column, so that the end of the extension section is the end of the buffer member 61 away from the joint 90 to be docked. In this way, when the buffer member 61 moves too far under the drive of the joint 90 to be docked, the range of movement of the buffer member 61 can be controlled by the abutment relationship between the extension section and the diverter, thereby avoiding the situation where the buffer member 61 is pushed excessively. The number of buffer components 60 can be set as needed. In this embodiment, a plurality of buffer components 60 are provided, more specifically, two are provided. The two buffer components 60 are respectively located on both sides of the length direction of the base 10, so that the base 10 is subjected to a balanced force as a whole and can move axially as a whole.

[0069] In this embodiment, the liquid cooling system splash prevention device also includes a reset member 70. Since the baffle cover 20 and the base 10 of this embodiment are connected in a rotatable manner, the reset member 70 adopts a torsion spring, and the two ends of the reset member 70 are respectively in contact with the baffle cover 20 and the base 10, so that the reset member 70 can provide a reset force for the baffle cover 20 to move to the shielding position, so that when the base 10 and the movable bracket 30 return to their original position, the baffle cover 20 can automatically re-shield the liquid cooling pipe joint 80 under the action of the reset member 70, thereby ensuring the splash prevention effect.

[0070] In an embodiment (not shown), the cover 20 is adapted to move with the base 10. The path of movement of the cover 20 relative to the base 10 forms an angle with the path of movement of the base 10 relative to the liquid-cooling pipe joint 80. Thus, when the liquid-cooling pipe joint 80 comes into contact with the cover 20, the cover 20 is driven by the liquid-cooling pipe joint 80 to tilt along its path, thereby avoiding the liquid-cooling pipe joint 80 and achieving docking between the two joint sections. In this case, the reset member 70 can be a linear spring.

[0071] The blocking cover 20 of this embodiment includes a main body and a rotating shaft portion, wherein the main body is curved or broken line-shaped, and the middle part of the main body protrudes in the direction away from the liquid cooling pipe joint 80, so that the shape of the main body can adapt to the liquid cooling pipe joint 80, ensuring the shielding effect. The rotating shaft portion is located at the side surfaces of the two ends of the main body that are away from each other. The rotating shaft portion is in the shape of a small cylinder, which cooperates with the hole groove opened on the base 10 to achieve a rotatable connection with the base 10, thereby enabling the blocking cover 20 as a whole to rotate around the rotating shaft portion, and the reset member 70 is sleeved on the rotating shaft portion. In this embodiment, the rotating shaft portion is preferably located outside the cross-sectional range of the liquid cooling pipe joint 80 perpendicular to the axis, so that the blocking cover 20 can completely avoid the liquid cooling pipe joint 80 when rotating, ensuring the convenience of docking between the joints.

[0072] The main body of this embodiment is arc-shaped as a whole, and includes two parts, namely a main body section in the form of an elongated strip and an extension section located on the side of the main body section, wherein the main body section is in the form of an elongated strip, and two rotating shaft parts are provided on the outer sides of its two ends to achieve rotatable cooperation with the base 10. Since the elongated shape of the main body section makes it impossible to completely cover the entire opening of the liquid cooling pipe joint 80, an extension section is provided on the side of the long side of the main body section, and the extension section extends along the surface where the main body section is located, so that the extension section serves as a compensation for the area that the main body section cannot cover, and covers other areas of the opening of the liquid cooling pipe joint 80, thereby improving the overall coverage range of the main body as a whole, ensuring the shielding effect of the cover 20 on the liquid cooling pipe joint 80, and further ensuring the anti-splashing effect.

[0073] In this embodiment, the base 10 is in the shape of a shell that is set up separately, which includes a first base body 11 and a second base body 12. The first base body 11 and the second base body 12 both adopt a semi-enclosed structure. In this way, the first base body 11 and the second base body 12 can be docked to form a cavity surrounded on all sides. The base 10 of this embodiment adopts a rectangular structure, and the cavity is also rectangular. Of course, the base 10 can also adopt other shapes. Considering that the docking between the liquid-cooling pipe joint 80 and the joint to be docked 90 needs to pass through the base, this embodiment is provided with through holes on both sides of the cavity, and the through holes on the opposite sides are axially aligned, so that the liquid-cooling pipe joint 80 and the joint to be docked 90 can be docked with the through holes on the opposite sides respectively extending into the cavity, or the liquid-cooling pipe joint 80 can pass through the cavity from the two through holes and extend out of the base 10 to achieve docking with the joint to be docked 90.

[0074] In this embodiment, the first base body 11 and the second base body 12 are connected by a snap-fit ​​docking method. Specifically, a snap-fit ​​structure is provided on one of the first base body 11 and the second base body 12, and a slot structure is provided on the other. The specific positions and numbers of the snap-fit ​​structure and the slot structure can be adjusted as needed to cover all docking sides as much as possible. During assembly, a stable connection between the two base bodies is achieved through the cooperation between the snap-fit ​​structure and the slot structure.

[0075] Since the diverter used in this embodiment is provided with a guide post, this embodiment utilizes the guide post on the diverter. To ensure that the guide post on the diverter can cooperate with the movable bracket 30 and the elastic member 40, this embodiment further provides guide holes on the front and rear surfaces of the first base 11 and the second base 12 relative to each other. The position of the guide holes is aligned with the axial direction of the elastic member 40. Thus, when the base 10 is installed on the diverter, the guide post can be inserted into the guide hole, the connection hole, and the elastic member 40, thereby guiding the movement of the base 10, the movable bracket 30, and the elastic member 40. Of course, additional guide posts can also be provided on the base 10 and the movable bracket 30 for guidance.

[0076] Preferably, the base 10, movable bracket 30, mounting base 50, and cover 20 of this embodiment are all made of plastic. The base 10 has a certain degree of transparency, for example, 30% transparency, so that the collection of overflow liquid in the base and the docking of the connector can be observed from the outside.

[0077] Based on the specific application scenario of this embodiment, when multiple liquid-cooling pipe joints 80 and docking joints 90 are provided, the number of components and structures such as the cover 20, the connection holes 31 of the movable bracket 30, and the through-holes of the cavity can be increased accordingly. For example, in this embodiment, taking the example of two liquid-cooling pipe joints 80 and two docking joints 90, two cover 20 are provided, and two connection holes 31 are also provided in parallel on the movable bracket 30. The cavity has four through-holes, and two through-holes are provided in parallel on two opposing sides of the cover 20, thereby achieving the effect of matching two liquid-cooling pipe joints 80.

[0078] The base 10 of this embodiment can be provided with an outflow channel as needed. The outflow channel is connected to the cavity and extends to an external component for collecting overflow liquid. This allows overflow liquid collected within the base 10 to be directed to a specific collection component for centralized collection and processing. The outflow channel can be formed by the structure of the base 10 itself or by a separate tube or other structure.

[0079] This embodiment also provides a liquid cooling cabinet, including a flow divider, a node server, and the aforementioned liquid cooling system splash guard. The flow divider is a liquid cooling pipe and return device on the liquid cooling cabinet, fixed to the rear end of the liquid cooling cabinet, providing liquid heat dissipation and liquid recovery for the entire cabinet, and has the aforementioned liquid cooling pipe joint 80. The node server is a separate cold plate structure design server. Each cabinet can accommodate multiple node servers to form a large integrated unit for systematic computing or storage, etc. It has the aforementioned docking joint 90. The liquid cooling system splash guard is movably arranged at the liquid cooling pipe joint 80. When the docking joint 90 is docked with the liquid cooling pipe joint 80, the node server drives the liquid cooling system splash guard to move to avoid the liquid cooling pipe joint 80. When the node server and the flow divider are docked, the liquid in the flow divider can be transferred to the interior of the server to achieve heat dissipation for components such as the CPU. Guide blocks, guide grooves, and other structures can be provided on the liquid cooling pipe joint 80 and the docking joint 90 to guide the docking between the two and improve the accuracy of the docking.

[0080] This embodiment also provides a server comprising a heat-generating device and the aforementioned liquid cooling cabinet. The liquid cooling cabinet interfaces with the heat-generating device via liquid cooling pipes and cools and dissipates heat from the heat-generating device. Of course, the liquid cooling cabinet can also be used in other devices, and the liquid cooling system splash guard can also be used in other devices within the liquid cooling cabinet.

[0081] The process of using the liquid cooling system splash protection device of this embodiment is as follows:

[0082] During assembly, separate the first and second base bodies 11 and 12, insert the elastic member 40 into the connection hole 31 of the movable bracket 30, attach the mounting base 50 to the diverter, install the reset member 70 and the cover 20 to the base body, assemble the buffer assembly 60 and insert it into the base body, butt-join the two base bodies together, and fit the elastic member 40 onto the guide post of the diverter with its end hooked onto the mounting base 50. After assembly, the liquid cooling pipe connector 80 is in the initial state, with the cover 20 covering the opening of the liquid cooling pipe connector 80, as shown in FIG9 .

[0083] When docking is required, the docking connector 90 moves toward the liquid cooling pipe connector 80. The node server contacts and squeezes the buffer 61. The buffer 61 squeezes the buffer elastic member 62. The buffer elastic member 62 acts on the base 10, thereby driving the base 10 to move toward the diverter. The movement of the base 10 squeezes the first elastic portion 41 of the elastic member 40, causing the elastic member 40 to be compressed as a whole. The elastic member 40 drives the movable bracket 30 to move axially toward the diverter through the intermediate connecting portion 43 in the middle. The movement of the movable bracket 30 causes the liquid cooling pipe connector 80 to move toward extending out of the base 10. The liquid cooling pipe connector 80 contacts and pushes the blocking cover 20, causing the blocking cover 20 to rotate, thereby pushing the blocking cover 20 from the blocking position to the avoidance position. The blocking cover 20 no longer blocks the liquid cooling pipe connector 80. At this time, the docking connector 90 also extends into the base 10, and the docking connector 90 can be plugged into the liquid cooling pipe connector 80, as shown in Figure 10. Due to the structural setting, some liquid may splash when the two are plugged into each other. At this time, the base 10 can collect the liquid.

[0084] When separation is required, the docking joint 90 is pulled out and moved away from the liquid cooling pipe joint 80. The node server gradually releases the squeeze on the buffer 61, and the buffer 61, the base 10 and the movable bracket 30 move in the opposite direction. The liquid cooling pipe joint 80 also moves in the opposite direction and exits the position of squeezing the cover 20. The cover 20 returns to the shielding position under the action of the reset member 70 until the node server is completely separated from the buffer 61 and the liquid cooling system splash guard returns to its initial state.

[0085] The technical solution of this embodiment has a simple architecture, is easy to implement, has reliable functions, and is versatile. It can be applied in many scenarios and is not limited to the server industry. Therefore, it can be widely used in many fields. The technical solution of this application is that the diverter can prevent liquid from flowing out when the node is not plugged in; secondly, it can suppress liquid splashing when the male and female heads of the liquid cooling pipe are docked and assembled, and ensure that after the liquid flows out, it can be received and diverted to the outside of the cabinet for collection; thirdly, there is no need to manually control the working state of the cover 20, and automatic control is achieved according to the docking requirements of the node and the diverter.

[0086] Example 2

[0087] The difference from the first embodiment is that the arrangement of the elastic member 40 is different.

[0088] As shown in Figures 11 and 12, in this embodiment, the elastic member 40 is not a single piece, but rather comprises two parts: a first elastic portion 41 and a second elastic portion 42, which are separately provided in two sections and are respectively connected to opposite sides of the movable bracket 30. Thus, the two sections of spring formed by the two elastic portions respectively achieve the coordination between the base 10 and the movable bracket 30, and between the movable bracket 30 and the liquid cooling component. When the base 10 is subjected to force, the base 10 first compresses the first elastic portion 41, and the compression of the first elastic portion 41 in turn causes the compression of the second elastic portion 42, thereby achieving the effect of driving the movable bracket 30 to move. At this time, in order to ensure the reliability of the connection between the spring and the movable bracket 30, a slot, a hook, or other structure can be provided on the movable bracket 30 to achieve reliable coordination with the spring end.

[0089] Specifically, the connection between the first elastic portion 41 and the second elastic portion 42 and the movable bracket 30 can be achieved in a variety of ways, such as by directly protruding a snap-fit ​​structure on the side of the movable bracket 30, thereby securing the first elastic portion 41 and the second elastic portion 42 to the movable bracket 30 via the snap-fit ​​structure. However, this embodiment employs an additional component. Specifically, the movable bracket 30 of this embodiment still has a through-hole, and the elastic member 40 also includes a locking member 44. The locking member 44 can be annular, etc., to facilitate adaptation to the shape of the through-hole, allowing the locking member 44 to be installed in the through-hole and thus penetrate the movable bracket 30. The locking member 44 can be provided with a snap-fit ​​structure. In this way, the ends of the first elastic portion 41 and the second elastic portion 42 can be connected to the locking member 44 through the engagement between the snap-fit ​​structures, thereby achieving the effect of connecting the first elastic portion 41 and the second elastic portion 42 to the movable bracket 30 via the locking member 44. Of course, the specific structure of the locking member 44 can be adjusted as needed and is not limited to the structure described in this embodiment.

[0090] Example 3

[0091] The liquid cooling system splash prevention device provided in this embodiment includes a base 10 and a cover 20. The base 10 has a cavity; the cover 20 is reversibly disposed within the cavity and can be flipped between a blocking position for blocking the liquid cooling pipe joint 80 and a retracting position for avoiding the liquid cooling pipe joint 80. The flipping of the cover 20 can be achieved through automated control, manual operation, or through coordination with other components similar to the first embodiment. Regardless of the method used, as long as the flipping of the cover 20 can be achieved to achieve coordination with the liquid cooling pipe joint 80 to block and avoid the liquid cooling pipe joint 80, it will be sufficient.

[0092] In this embodiment, the rotation axis of the blocking cover 20 is located on one side of the liquid-cooling pipe joint 80, so that the blocking cover 20 can completely exit the docking range of the liquid-cooling pipe joint 80 after flipping over to avoid it, ensuring that the blocking cover 20 will not affect the docking between the liquid-cooling pipe joint 80 and the joint 90 to be docked. In addition, the rotation axis of the blocking cover 20 is perpendicular to the axis of the liquid-cooling pipe joint 80. The axis of the liquid-cooling pipe joint 80 mentioned here refers to the axis in the length direction of the liquid-cooling pipe joint 80. In this way, the flipping of the blocking cover 20 can completely block or completely avoid the end opening of the liquid-cooling pipe joint 80. Of course, the specific setting form of the blocking cover 20 is not limited to the above-mentioned method of this embodiment, and it can also be adjusted as needed.

[0093] The blocking cover 20 of this embodiment has an arc-shaped structure, and when the blocking cover 20 is in the shielding position, the arc-shaped structure protrudes in the direction away from the liquid-cooling pipe joint 80. In this way, on the one hand, it can ensure the shielding effect of the liquid-cooling pipe joint 80 and the anti-splashing effect. At the same time, due to the arc-shaped structure, when the blocking cover 20 is in the avoidance position, the arc-shaped structure is flipped so that it can surround at least part of the circumferential side of the liquid-cooling pipe joint 80. At this time, the shape of the arc-shaped structure matches the circumferential side of the liquid-cooling pipe joint 80, so that the blocking cover 20 does not occupy extra space, thereby meeting the use requirements of a small space.

[0094] It should be noted that the specific structural form of the liquid cooling system splash prevention device of this embodiment can adopt the setting form of the liquid cooling system splash prevention device in Example 1, which can be completely the same or not completely the same, and can be adjusted accordingly as needed.

[0095] It should be noted that, in the above embodiments, a plurality refers to at least two.

[0098] 2. When the joints are butt-jointed and assembled, they can suppress liquid splashing and achieve the anti-splashing effect of the liquid cooling pipe joints;

[0099] 3. Suppress liquid splashing and ensure that the overflow can be collected after the liquid flows out to ensure that the cooling liquid does not affect the device;

[0100] 4. It does not affect the normal docking of pipelines, so that the joints of the pipelines can be freely docked and separated;

[0101] 5. There is no need to manually control the working status of the cover, and automatic control is achieved according to the docking requirements of the node and the diverter.
