[0033] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0037] In addition, in the embodiments of the present disclosure, directional terms such as "up", "down", "left" and "right" are defined relative to the positions of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0039] In the disclosed embodiments, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] In a data center, server cabinets are the core facilities for storing and managing servers. Server cabinets not only provide the necessary physical protection and environmental control, but also support efficient heat dissipation to ensure the stable operation of the data center.

[0042] The heat dissipation methods of server cabinets mainly include air cooling system heat dissipation and liquid cooling system heat dissipation. Air cooling system heat dissipation mainly achieves cooling of heating components through the cooperation of fans and air guide covers. Liquid cooling system heat dissipation is an efficient heat dissipation method that uses pipes to directly flow coolant through the heat source to achieve high-efficiency heat dissipation. However, in related liquid cooling systems, due to the complexity of pipes, leakage and failure are very likely to occur. How to quickly and effectively diagnose and troubleshoot possible leakage and failure of the pipes is an important and urgent technical challenge currently faced.

[0043] Figure 1 The structure diagram of the server liquid cooling system according to an embodiment of the present disclosure is schematically shown.

[0044] like Figure 1 As shown, the server liquid cooling system includes a cooling liquid distribution device 10 , a liquid cooling pipeline 20 and a configuration device 30 .

[0045] The cooling liquid distribution device 10 includes a liquid supply port and a liquid return port. The liquid supply port is used to output the cooling liquid. The liquid return port is used to return the cooling liquid. The liquid cooling pipeline 20 includes a liquid supply pipeline 21 and a liquid return pipeline 22. The liquid supply pipeline 21 and the liquid return pipeline 22 form a heat dissipation space along the target direction. The liquid supply pipeline 21 and the liquid return pipeline 22 each include a set of multiple sections of detachably connected branch pipe components, which can be freely combined or disassembled. The configuration device 30 includes a liquid separation device 31 and a liquid collection device 32. The liquid separation device 31 is connected to the liquid supply port through the liquid supply pipeline 21. The liquid collection device 32 is connected to the liquid return port through the liquid return pipeline 22.

[0046] Specifically, the working process of the server liquid cooling system is as follows: the coolant distribution device 10 outputs the coolant to the liquid supply pipeline 21 through the liquid supply port, and the coolant is transported to the liquid distribution device 31 through the liquid supply pipeline 21. The liquid distribution device 31 distributes the coolant from the liquid supply pipeline 21 to each server to be cooled. After the coolant absorbs heat in the server, the temperature rises and is transported to the return liquid pipeline 22 through the liquid collection device 32. The return liquid pipeline 22 returns the coolant with the increased temperature to the coolant distribution device 10 through the return liquid port for cooling. This cycle is repeated in sequence to achieve continuous cooling of the server.

[0047] Among them, the above-mentioned server can adopt an indirect liquid cooling server to adapt to the server liquid cooling system provided by the present disclosure. Indirect liquid cooling can be a cold plate liquid cooling, in which the coolant circulates in a closed cold plate, and the cold plate exchanges heat with the heat-generating components in the server through heat-conducting materials. Specifically, the cold plate arranged in the indirect liquid cooling server is connected to the liquid separation device 31 and the liquid collection device 32 through two pipelines, and the coolant delivered from the liquid collection device 32 is delivered to the cold plate through the pipeline. When the coolant flows in the cold plate, it takes away the heat on the cold plate by heat conduction. The coolant carrying the heat is then delivered to the liquid collection device 32 through the pipeline, and then flows back to the coolant distribution device 10.

[0048] In some embodiments, multiple sections of detachably connected branch pipe assemblies can be combined using connectors. The connectors are used to connect adjacent unit pipes, and multiple unit pipes can be detachably connected through the connectors to improve the stability and reliability of the branch pipe assembly. The detachable connection can be a threaded connection, a flange connection, a clamp connection, a joint connection, etc., and the present disclosure does not limit this.

[0049] The target direction can be determined based on the layout of the server liquid cooling system and the fluid flow requirements. Figure 1As shown, for example, the target direction is parallel to the direction in which the configuration device 30 is placed. In this target direction, the liquid cooling pipeline 20 can be set at the bottom of the target direction, and a heat dissipation space can be formed above the liquid cooling pipeline 20. When the server liquid cooling system is working, the heat dissipation space can not only transfer the heat of the coolant in the return liquid pipeline to the outside world, but also transfer the heat of the server to the outside world.

[0050] In some embodiments, a heat dissipation device such as a fan or a radiator may be provided in the heat dissipation space to promote air flow and accelerate the heat exchange process, thereby further improving the heat dissipation effect.

[0051] Through the above-mentioned embodiments of the present disclosure, in order to adapt to equipment of different sizes, by setting the liquid supply pipeline 21 and the liquid return pipeline 22 to each include a set of multiple sections of detachably connected branch pipe components, each section can be freely combined. In the case where the server liquid cooling system needs to be set in equipment of different sizes, the liquid supply pipeline 21 and the liquid return pipeline 22 can be freely combined to achieve adjustment in length and layout to adapt to equipment of different sizes.

[0052] Through the above-mentioned embodiments of the present disclosure, in order to quickly troubleshoot, by setting the liquid supply pipeline 21 and the liquid return pipeline 22 to each include a group of multiple sections of detachably connected branch pipe assemblies, each section can be freely disassembled. In the event of a leak or failure in the liquid supply pipeline or the liquid return pipeline, by disassembling the branch pipe, multiple branch pipes can be quickly checked for leaks or failures at the same time, thereby reducing the maintenance time of the server liquid cooling system pipeline. Furthermore, in the event of a leak in the pipeline, it is not necessary to replace the entire pipeline, only the leaking branch pipe needs to be replaced, thereby reducing the maintenance time of the server liquid cooling system pipeline.

[0053] Through the above-mentioned embodiments of the present disclosure, in order to drain water quickly, by setting the liquid supply pipeline 21 and the liquid return pipeline 22 to each include a set of multiple sections of detachably connected branch pipe assemblies, each section can be freely disassembled. The multiple sections of detachably connected branch pipe assemblies are disassembled to separate multiple drainage ports. When the coolant in the pipeline needs to be discharged, multiple drainage can be achieved through these multiple drainage ports, which helps to disperse the water flow, avoid overloading of a single drainage port, and improve drainage efficiency.

[0054] Figure 2 Schematically illustrates an embodiment of the present disclosure Figure 1 A partial enlarged view of part A in the server liquid cooling system is shown.

[0055] like Figure 2As shown, the multi-section detachably connected branch pipe assembly includes at least one section of hard pipe 200 and two groups of pipes 201 connected to both ends of the hard pipe 200. The two groups of pipes 201 are respectively connected to both ends of the hard pipe 200 and are connected to the hard pipe 200 by a detachable connection. The hard pipe 200 is used to connect and support the two groups of pipes 201. The rigid structure of the hard pipe 200 enables the liquid supply pipeline 21 and the liquid return pipeline 22 to maintain a stable shape and flow direction, ensuring the stable transmission of the coolant in the system. The hard pipe 200 is fixedly arranged on one side of the configuration device 30, and the position of the hard pipe 200 and the configuration device 30 are associated, making the structure of the entire server liquid cooling system more compact.

[0056] Among them, one set of pipes in the two sets of pipes 201 is connected to the coolant distribution device 10 for transmitting the coolant, and the other set of pipes in the two sets of pipes 201 is connected to the configuration device 30 to realize the circulation of the coolant in the configuration device 30.

[0057] In some embodiments, each of the two groups of pipes 201 may include one or more detachably connected branch pipes, which may be hard pipes, or soft pipes, or a combination of soft pipes and hard pipes.

[0058] In some embodiments, the two groups of pipes 201 connected to the two ends of the hard tube 200 include hoses. The hoses are used to adjust their own shapes so that heat dissipation spaces are formed between the hoses, and the heat dissipation spaces are used for heat exchange through air flow. Since the hoses have excellent flexibility, they can easily adjust their own shapes to adapt to different installation environments and space requirements. Through shape adjustment, heat dissipation spaces can be formed between the hoses, and these heat dissipation spaces provide channels for air flow, thereby enhancing the heat dissipation effect.

[0059] In some embodiments, one of the two groups of pipes 201 connected to both ends of the hard pipe 200 is a hard pipe, and the other group of pipes is a soft pipe. Among them, the group of pipes that are hard pipes can be used to connect the coolant distribution device 10, that is, one hard pipe is connected to the liquid supply port of the coolant distribution device 10, and the other hard pipe is connected to the liquid return port of the coolant distribution device 10, so as to achieve the coolant stable outflow and inflow of the coolant distribution device 10. The group of pipes that are soft pipes can be used to connect the configuration device 30, that is, one soft pipe is connected to the liquid inlet of the liquid separation device 31, and the other hard pipe is connected to the liquid outlet of the liquid collection device 32. Due to the advantage of the adjustable hose, it can be adapted to the liquid separation device 31 with different liquid inlet heights and the liquid collection device 32 with different liquid outlet heights.

[0060] The above-mentioned hose can be a hose with a fixed length, such as a stainless steel hose, a metal hose, a plastic hose, a rubber hose, etc. The above-mentioned hose can also be a hose with a variable length, such as a telescopic hose, a bellows, a spiral hose, etc. The hose with a variable length can be freely extended and bent under different working conditions to adapt to various displacements and deformations of the pipeline, such as axial, lateral and angular displacements, so as to effectively adjust the heat dissipation space formed.

[0061] In some embodiments, a seal may be provided between two connected branch pipes to prevent leakage of the coolant from the interface between the two branch pipes.

[0062] In some embodiments, the hard tube 200 is arranged along the target direction. Figure 3 As shown, the target direction is parallel to the direction in which the configuration device 30 is placed, and the liquid supply flow direction of the hard tube 200 can be high-in and low-out, that is, the coolant enters the hard tube 200 from a high place and then flows out from a low place to meet the flow rate and flow velocity. This flow direction design helps to utilize the effect of gravity to promote the natural flow of the coolant and reduce the workload of the coolant distribution device 10. For another example, Figure 1 As shown, the liquid supply flow direction of the hard tube 200 can also be low-in and high-out, that is, the coolant enters the hard tube 200 from a low place and then flows out from a high place, reducing the impact of the coolant flow on the pipeline.

[0063] In some embodiments, the liquid supply pipeline 21 and the liquid return pipeline 22 are arranged in a U shape along the target direction, so that the liquid supply pipeline 21 and the liquid return pipeline 22 both form a U-shaped space. The liquid supply pipeline 21 is placed through the U-shaped space of the liquid return pipeline 22, and the liquid return pipeline 22 is placed through the U-shaped space of the liquid supply pipeline 31. This cross-placement method can greatly save space when placing the server liquid cooling system into the cabinet.

[0064] In some embodiments, the target direction is parallel to the direction in which the configuration device 30 is placed. As the supporting part of the U-shaped space formed by the liquid supply pipeline 21, the hard tube 200 in the liquid supply pipeline 21 can be a U-shaped hard tube 200, the bottom of the U-shaped hard tube 200 in the liquid supply pipeline 21 is fixedly set on one side of the liquid collection device 32, and the liquid inlet of the U-shaped hard tube 200 is placed higher than the liquid outlet of the U-shaped hard tube 200. Similarly, as the supporting part of the U-shaped space formed by the liquid return pipeline 22, the hard tube 200 in the liquid return pipeline 22 can be a U-shaped hard tube 200, the bottom of the U-shaped hard tube 200 in the liquid return pipeline 22 is fixedly set on one side of the liquid separation device 31, and the liquid inlet of the U-shaped hard tube 200 is placed higher than the liquid outlet of the U-shaped hard tube 200, so as to achieve effective support for the liquid supply pipeline 21 and the liquid return pipeline 22, and at the same time greatly save the space occupied by the liquid supply pipeline 21 and the liquid return pipeline 22.

[0065] In some embodiments, the hard tube 200 in the liquid supply pipeline 21 can be an L-shaped hard tube 200. One side of the L-shaped hard tube 200 in the liquid supply pipeline 21 is fixedly disposed on one side of the liquid collecting device 32. Similarly, one side of the L-shaped hard tube 200 in the liquid return pipeline 22 is fixedly disposed on one side of the liquid dispensing device 31.

[0066] In some embodiments, the liquid supply line 21 and the liquid return line 22 may be at the same height. The liquid supply line 21 and the liquid return line 22 at the same height may reduce the occupation of the surrounding environment, effectively utilize space, and improve space utilization. The liquid supply line 21 and the liquid return line 22 at the same height may also reduce the pressure loss during the liquid supply and liquid return process at the same height, minimize the gravity effect caused by the height difference, and make the coolant flow more smoothly in the liquid supply line 21 and the liquid return line 22, thereby improving the overall efficiency of the server liquid cooling system.

[0067] In some embodiments, the liquid supply pipeline 21 and the liquid return pipeline 22 may also be at different heights. The liquid supply pipeline 21 and the liquid return pipeline 22 at different heights make the layout of the server liquid cooling system more flexible and can be laid out according to actual space requirements.

[0068] In some embodiments, the liquid outlet height of the liquid supply port on the coolant distribution device 10 is higher than the liquid inlet height of the liquid return port on the coolant distribution device 10. Combined with the high-in and low-out liquid supply flow direction of the hard pipe 200, it can be ensured that the coolant can quickly flow into the server through the liquid distribution device 31 in a high-in and low-out manner to dissipate heat for the server, and reduce the temperature loss of the coolant during the rapid inflow process. At the same time, the coolant refluxed through the liquid collection device 32 flows into the coolant distribution device 10 relatively slowly in a low-in and high-out manner, increasing the heat dissipation of the coolant during the slow reflux process.

[0069] In some embodiments, the liquid outlet height of the liquid supply port on the coolant distribution device 10 is lower than or equal to the liquid inlet height of the liquid return port on the coolant distribution device 10, which can avoid the coolant having to overcome greater gravity during the circulation process and reduce the resistance to the coolant flow.

[0070] In some embodiments, the liquid supply direction of the liquid supply pipeline 21 is opposite to the liquid return direction of the liquid return pipeline 22. On the one hand, the coolant with a relatively low temperature in the liquid supply pipeline 21 and the coolant with a relatively high temperature in the liquid return pipeline 22 can be separated from each other, so as to prevent the coolant with a relatively high temperature in the liquid return pipeline 22 from raising the temperature of the coolant with a relatively low temperature in the liquid supply pipeline 21. On the other hand, the layout of the liquid supply pipeline 21 and the liquid return pipeline 22 can be made clearer.

[0071] In some embodiments, Figure 2As shown, the liquid supply port of the coolant distribution device 10 is connected to the liquid supply pipeline 21 via a water channel control device 40 , and the water channel control device 40 is at least used to disconnect the water channel between the coolant distribution device 10 and the liquid supply pipeline 21 .

[0072] In some embodiments, Figure 2 As shown, the liquid return port of the coolant distribution device 10 is connected to the liquid return pipeline 22 via a water circuit control device 40 , and the water circuit control device 40 is at least used to disconnect the water circuit between the coolant distribution device 10 and the liquid return pipeline 22 .

[0073] In some embodiments, Figure 2 As shown, the liquid inlet of the liquid separation device 31 is connected to the liquid supply pipeline 21 through a water circuit control device 40. The water circuit control device 40 is at least used to disconnect the water circuit between the liquid separation device 31 and the liquid supply pipeline 21, which can facilitate the maintenance of the liquid separation device 31.

[0074] In some embodiments, Figure 2 As shown, the liquid outlet of the liquid collecting device 32 is connected to the liquid return pipeline 22 via a water circuit control device 40. The water circuit control device 40 is at least used to disconnect the water circuit between the liquid collecting device 32 and the liquid return pipeline 22, so as to facilitate the maintenance of the liquid collecting device 32.

[0075] In the above embodiment, the water channel control device 40 can also control the flow rate and flow rate of the coolant. When the load of the data center is low, the energy consumption is reduced by reducing the flow rate and / or flow rate of the coolant. When the load of the data center is high, the flow rate and / or flow rate of the coolant is increased to ensure the normal operation of the data center and rational use of resources.

[0076] In the above embodiment, the waterway control device 40 can be a common ball valve or a quick-connect ball valve. The quick connector design of the quick-connect ball valve makes the installation and removal process simpler and faster, without the need for complex tools or a lot of time. This feature makes the quick-connect ball valve more efficient and convenient during the maintenance, replacement or adjustment of the waterway system.

[0077] In some embodiments, a water circuit control device 40 is provided between the liquid supply port of the coolant distribution device 10 and the liquid supply pipeline 21, and between the liquid inlet of the liquid distribution device 31 and the liquid supply pipeline 21. When the liquid supply pipeline 21 needs to be inspected and the coolant needs to be discharged, the water circuit control device 40 between the liquid supply port of the coolant distribution device 10 and the liquid supply pipeline 21, and between the liquid inlet of the liquid distribution device 31 and the liquid supply pipeline 21 is disconnected, so that the coolant in the liquid supply pipeline 21 can flow out from both ends, thereby accelerating the discharge of the coolant. The disconnected liquid supply pipeline is also easier to inspect.

[0078] In some embodiments, a water circuit control device 40 is provided between the return liquid port of the coolant distribution device 10 and the return liquid pipeline 22, and between the liquid outlet of the liquid collection device 32 and the return liquid pipeline 22. When the return liquid pipeline 22 needs to be inspected and the coolant needs to be discharged, the water circuit control device 40 between the return liquid port of the coolant distribution device 10 and the return liquid pipeline 22, and between the liquid outlet of the liquid collection device 32 and the return liquid pipeline 22 is disconnected, so that the coolant in the return liquid pipeline 22 can flow out from both ends, thereby accelerating the discharge of the coolant. The disconnected liquid supply pipeline is also easier to inspect.

[0079] In some embodiments, a water circuit control device 40 is provided between the liquid supply port of the cooling liquid distribution device 10 and the liquid supply pipeline 21, and between the liquid return port of the cooling liquid distribution device 10 and the liquid return pipeline 22. By disconnecting the water circuit control device 40 between the liquid supply port of the cooling liquid distribution device 10 and the liquid supply pipeline 21, and between the liquid return port of the cooling liquid distribution device 10 and the liquid return pipeline 22, the cooling liquid distribution device 10 can be easily inspected, replaced or maintained, and the cooling liquid leakage is prevented from affecting other system components, thereby protecting the safety of the data center.

[0080] It can be understood that whether to set the water circuit control device 40 between the liquid supply port and the liquid supply pipeline 21 of the above coolant distribution equipment 10, between the return liquid port and the return liquid pipeline 22 of the coolant distribution equipment 10, between the liquid inlet of the liquid separation equipment 31 and the liquid supply pipeline 21, and between the liquid outlet of the liquid collection equipment 32 and the return liquid pipeline 22 can be freely selected.

[0081] In some embodiments, at least one liquid separation flow port 311 located at the upper end of the liquid separation device 31 is used to discharge the gas in the coolant when the exhaust valve is inserted, and / or, at least one liquid collection flow port 322 located at the upper end of the liquid collection device 32 is used to discharge the gas in the coolant when the exhaust valve is inserted.

[0082] It is understandable that a certain amount of air is usually dissolved in the coolant. When the coolant circulates in the server liquid cooling system, as the water temperature rises, the solubility of the air will decrease, and the air will gradually separate and form bubbles. These bubbles will rise to the high point of the pipeline with the water flow. The liquid separation flow port 311 at the upper end of the liquid separation device 31 and / or the liquid collection flow port 322 at the upper end of the liquid collection device 32 are used as exhaust ports. When exhausting, the exhaust valve is inserted into the exhaust port. The float or buoy inside the exhaust valve will rise due to the buoyancy of the gas, thereby driving the valve to open and discharge the gas.

[0083] In some embodiments, the liquid dispensing device 31 is provided with a plurality of liquid dispensing openings 311, and the liquid collecting device 32 is provided with a plurality of liquid collecting openings 322. The liquid dispensing openings 311 and the liquid collecting openings 322 located at the same height along the target direction are used to connect to the server for liquid cooling and heat dissipation. The liquid dispensing openings 311 and the liquid collecting openings 322 are both connected to the server through pipelines, so that the heat emitted by the server is taken away by the coolant flowing in the pipelines.

[0084] Figure 3 The structure diagram of a server cooling system according to an embodiment of the present disclosure is schematically shown.

[0085] like Figure 3 As shown, the server heat dissipation system includes a cabinet body 1000 and a server liquid cooling system. A server 50 is placed in the cabinet body, and the server 50 includes at least a liquid-cooled server. The server liquid cooling system includes: a cooling liquid distribution device 10, a liquid cooling pipeline 20 and a configuration device 30. The cooling liquid distribution device 10 includes a liquid supply port and a liquid return port, the liquid supply port is used to output the cooling liquid, and the liquid return port is used to return the cooling liquid. The liquid cooling pipeline 20 includes a liquid supply pipeline 21 and a liquid return pipeline 22, the liquid supply pipeline 21 and the liquid return pipeline 22 form a heat dissipation space along the target direction, and the liquid supply pipeline 21 and the liquid return pipeline 22 both include a group of multiple sections of detachably connected branch pipes. The configuration device 30 includes a liquid separation device 31 and a liquid collection device 32, which are respectively arranged on the two side panels of the cabinet body. The liquid separation device 31 is connected to the liquid supply port of the cooling liquid distribution device 10 through a liquid supply pipeline, and the liquid collection device 32 is connected to the liquid return port of the cooling liquid distribution device 10 through a liquid return pipeline. The liquid separation device 31 and the liquid collection device 32 both include multiple liquid flow ports, and the multiple liquid flow ports perform heat exchange with the liquid-cooled server through pipelines with cooling liquid flowing therein.

[0086] Through the embodiment of the present disclosure, the liquid separation device 31 and the liquid collection device 32 are respectively arranged on the two side panels of the cabinet body, which can effectively utilize the idle space on the side of the cabinet, reduce the occupation of the rear space of the cabinet, and also help reduce the interference caused by the cables behind the cabinet. The saved rear space can be used to place a server 50 with a larger depth, such as a large server, an air-cooled server, etc.

[0087] like Figure 3As shown, in the cabinet body, the server 50 is arranged in the front space of the cabinet body 1000, and the cooling liquid distribution device 10 can be arranged in the front space of the cabinet body 1000 or outside the cabinet body 1000. When the server 50 and the cooling liquid distribution device 10 are both arranged in the front space of the cabinet body 1000, the cooling liquid distribution device 10 can be arranged above the server 50, below the server 50 or between the servers 50. Since the liquid cooling pipeline 20 and the cooling liquid distribution device 10 are located in the same height range, the position of the liquid cooling pipeline 20 is located above the server 50, below the server 50 or between the servers.

[0088] In some embodiments, Figure 3 As shown, the cooling liquid distribution device 10 is arranged at the lower part of the server 50, that is, the cooling liquid distribution device 10 and the liquid cooling pipeline 20 are arranged at the bottom of the cabinet body 1000, which can only occupy the 4U space at the bottom of the cabinet 1000, and the structure is simpler, reducing the risk of leakage. The multiple sections of detachable and connected branch pipes include a section of hard pipe 200 and two groups of pipes 201 connected to both ends of the hard pipe 200. The hard pipe 200 is fixedly arranged on one side of the configuration device 30. The hard pipe 200 is used to support the liquid cooling pipeline 20. One of the two groups of pipes 201 is connected to the cooling liquid distribution device 10, and the other group of pipes in the two groups of pipes 201 is connected to the configuration device 30.

[0089] In some embodiments, when the coolant distribution device 10 and the liquid cooling pipeline 20 are arranged at the bottom of the cabinet body, the two groups of pipes 201 connected to the two ends of the hard pipe 200 are hoses, and the hoses are used to adjust their own shapes so that a heat dissipation space is formed between the hoses. The heat dissipation space is used to perform heat exchange with the server 50 through air flow.

[0090] In some embodiments, the hard tube 200 is movably arranged along a target direction to adjust the position and size of the heat dissipation space. The target direction may be toward the top of the cabinet body 1000 or toward the bottom of the cabinet body 1000. Figure 3 As shown, taking the liquid cooling pipeline 20 disposed at the bottom of the cabinet body 1000 as an example, when the hard pipe 200 is adjusted toward the top of the cabinet body 1000, the space occupied by the liquid cooling pipeline 20 will increase, the heat dissipation space formed by the liquid cooling pipeline 20 will also increase, and the position of the heat dissipation space will be adjusted upward. When the hard pipe 200 is adjusted toward the bottom of the cabinet body 1000, the space occupied by the liquid cooling pipeline will decrease, the heat dissipation space formed by the liquid cooling pipeline 20 will decrease, and the position of the heat dissipation space will be relatively adjusted downward.

[0091] In some embodiments, Figure 3As shown, the liquid dispensing device 31 and the liquid collecting device 32 are respectively arranged on the two side panels of the cabinet body 1000 to form a placement space, wherein, in the case where the server 50 includes an air-cooled server, the air-cooled server is at least partially located in the placement space and is arranged corresponding to the heat dissipation space. Since the depth of most air-cooled servers is greater than the depth of liquid-cooled servers, when it is necessary to place air-cooled servers and liquid-cooled servers in the cabinet body 1000 at the same time, since it is necessary to keep the front of the cabinet body 1000 flat, at the rear of the cabinet body 1000, the air-cooled server will protrude a part of the liquid-cooled server along the depth direction of the cabinet body 1000. By respectively arranging the liquid dispensing device 31 and the liquid collecting device 32 on the two side panels of the cabinet body 1000 to form a placement space, the protruding part of the air-cooled server along the depth direction can be placed by occupying the placement space, and the air-cooled server and the liquid-cooled server can be placed simultaneously in the cabinet body 1000 to meet different needs.

[0092] Among them, the air-cooled server relies on air flow to achieve heat dissipation. The air-cooled server introduces external cold air into the air-cooled server through a fan, and performs heat exchange with the hot air generated by the air-cooled server, thereby reducing the temperature of the air-cooled server. The air-cooled server can be set adjacent to the coolant distribution device 10 or arbitrarily set in the cabinet body 1000. By setting the air-cooled server and the heat dissipation space correspondingly, the heat emitted by the air-cooled server can be effectively and timely dissipated through the heat dissipation space and the placement space, so that the server heat dissipation system provided by the embodiment of the present disclosure can simultaneously support air-cooled heat dissipation and liquid-cooled heat dissipation.

[0093] In some embodiments, the liquid supply flow direction of the rigid tube 200 is high in and low out. Alternatively, the liquid supply flow direction of the rigid tube 200 is low in and high out.

[0094] In some embodiments, the liquid supply pipeline 21 and the liquid return pipeline 22 are arranged in a U shape along the target direction, so that the liquid supply pipeline 21 and the liquid return pipeline 22 each form a U-shaped space, the liquid supply pipeline 21 is placed through the U-shaped space of the liquid return pipeline 22, and the liquid return pipeline 22 is placed through the U-shaped space of the liquid supply pipeline 21.

[0095] In some embodiments, the liquid outlet height of the liquid supply port on the cooling liquid distribution device 10 is higher than the liquid inlet height of the liquid return port on the cooling liquid distribution device 10, and the liquid supply direction of the liquid supply pipeline 21 is opposite to the liquid return direction of the liquid return pipeline 22.

[0096] In some embodiments, the liquid supply port of the coolant dispensing device 10 is connected to the liquid supply pipeline 21 via a water circuit control device 40 , and the water circuit control device 40 is at least used to disconnect the water circuit between the coolant dispensing device 10 and the liquid supply pipeline 21 .

[0097] In some embodiments, the liquid return port of the coolant distribution device 10 is connected to the liquid return pipeline 22 via a water circuit control device 40 , and the water circuit control device 40 is at least used to disconnect the water circuit between the coolant distribution device 10 and the liquid return pipeline 22 .

[0098] In some embodiments, the liquid inlet of the liquid separation device 31 is connected to the liquid supply pipeline 21 via a water channel control device 40 , and the water channel control device 40 is at least used to disconnect the water channel between the liquid separation device 31 and the liquid supply pipeline 21 .

[0099] In some embodiments, the liquid outlet of the liquid collection device 32 is connected to the liquid return pipeline 22 via a water circuit control device 40 , and the water circuit control device 40 is at least used to disconnect the water circuit between the liquid collection device 32 and the liquid return pipeline 22 .

[0100] In some embodiments, the liquid separation device 31 includes a plurality of liquid separation openings 311 , and at least one liquid separation opening 311 located at the upper end of the liquid separation device 31 is used to discharge gas in the coolant when an exhaust valve is inserted.

[0101] In some embodiments, the liquid collecting device 32 includes a plurality of liquid collecting openings 322 , and at least one liquid collecting opening 322 located at the upper end of the liquid collecting device 32 is used to discharge gas in the coolant when an exhaust valve is inserted.

[0102] In some embodiments, the liquid separation flow port 311 and the liquid collection flow port 322 located at the same height along the target direction are used to connect the server 50 to perform liquid cooling and heat dissipation.

[0103] Figure 4 The structure diagram of another server cooling system according to an embodiment of the present disclosure is schematically shown. Figure 4 As shown, the cooling liquid distribution device 10 and the liquid cooling pipeline 20 are arranged outside the cabinet body 1000, and the multiple sections of detachable connected branch pipes are all hoses. The cooling liquid distribution device 10 and the liquid cooling pipeline 20 can be operated more easily, and the cooling liquid distribution device can be maintained without opening the cabinet door or performing complicated internal operations, and the damage caused to other devices inside the cabinet body 1000 by the leakage of the cooling liquid distribution device 10 can also be avoided.

Although the embodiments are described above separately, this does not mean that the measures in the various embodiments cannot be used in combination to advantage.
