Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a cabinet and a server system. Background Art

[0002] With the continuous evolution of data centers, the power consumption of servers is increasing. The existing air cooling cannot meet the demand, and the heat dissipation problem of servers has gradually developed towards liquid cooling.

[0003] Liquid-cooled server systems consist of a cabinet and servers, with the servers housed within the cabinet. Typically, the liquid cooling lines are located on the back of the cabinet, while the server's liquid inlet and outlet ports are located on the front. Adapter lines are installed within the server's casing, connecting the liquid cooling lines to the inlet and outlet ports. This increases the design complexity of the server casing and makes it difficult to adapt to different servers, limiting its versatility. Summary of the Invention

[0004] The embodiments of the present application provide a cabinet and server system that can conveniently transfer the liquid cooling pipeline on one side of the cabinet to the other side of the cabinet, with a simple structure and wide compatibility.

[0005] In a first aspect, embodiments of the present application provide a cabinet comprising a cabinet body, a liquid inlet pipeline, a liquid return pipeline, and a liquid separation device. The cabinet body comprises at least a first side surface and a second side surface. Both the liquid inlet pipeline and the liquid return pipeline are disposed on the first side surface. The liquid inlet pipeline is used for the inflow of a liquid cooling medium, while the liquid return pipeline is used for the outflow of the liquid cooling medium. The liquid separation device is arranged in the cabinet; the liquid separation device includes a liquid inlet transfer pipe system and a liquid return transfer pipe system, wherein the liquid inlet transfer pipe system has a first liquid inlet, a first liquid outlet and a liquid inlet transfer passage, the first liquid inlet is connected to the first liquid outlet through the liquid inlet transfer passage, the first liquid inlet is located on the first side and is used to be connected to the liquid inlet pipeline, the first liquid outlet is located on the second side and is used to be connected to the heat dissipation component; the liquid return transfer pipe system has a second liquid inlet, a second liquid outlet and a liquid return transfer passage, the second liquid inlet is connected to the second liquid outlet through the liquid return transfer passage, the second liquid inlet is located on the second side and is used to be connected to the heat dissipation component, the second liquid outlet is located on the first side and is used to be connected to the liquid return pipeline.

[0006] In this way, through the setting of the liquid separation device, the liquid inlet pipeline and the liquid return pipeline on one side of the cabinet body can be transferred to the other side of the cabinet body, which is convenient for the liquid inlet pipeline, the liquid return pipeline to be connected with the liquid cooling inlet and outlet of the heat sink of the server set in the cabinet; the liquid separation device has a simple structure and is independent of the cabinet body. In actual application, it can be flexibly set according to needs, providing conditions for matching different servers and has wide compatibility.

[0007] In one possible implementation, the liquid inlet transfer pipe system includes at least one liquid inlet transfer pipe. One end of each liquid inlet transfer pipe forms a first liquid inlet, and the other end forms a first liquid outlet. The lumen of each liquid inlet transfer pipe forms a liquid inlet transfer passage. This allows for a one-to-one connection between the liquid inlet pipe interface and the server's liquid cooling inlet.

[0008] In one possible implementation, the liquid inlet transfer pipe system includes a first liquid inlet main pipe, a first liquid inlet manifold, and two or more first liquid inlet branch pipes. The first liquid inlet manifold has two or more first inlets, a first outlet, and a first liquid inlet sub-cavity, with each first inlet connected to a first outlet via the first liquid inlet sub-cavity. One pipe port of each first liquid inlet branch pipe forms a first liquid inlet, and another pipe port connects to a first inlet. One pipe port of the first liquid inlet main pipe connects to the first outlet, and another pipe port forms a first liquid outlet. In this way, a one-to-many transfer between the liquid inlet pipeline interface and the liquid cooling inlet of the server can be achieved.

[0009] In one possible implementation, the liquid inlet transfer pipe system includes a second liquid inlet main pipe, a second liquid inlet manifold, and two or more second liquid inlet branch pipes. The second liquid inlet manifold has a second inlet, two or more second outlets, and a second liquid inlet sub-cavity. The second inlet is connected to each second outlet via a first liquid inlet sub-cavity. One pipe port of the second liquid inlet main pipe forms the first liquid inlet, and another pipe port is connected to the second inlet. One pipe port of each second liquid inlet branch pipe is connected to a second outlet, and another pipe port forms a first liquid outlet. In this way, a many-to-one transfer between the liquid inlet pipe interface and the server's liquid cooling inlet can be achieved.

[0010] In one possible implementation, the liquid return transfer pipe system includes at least one liquid return transfer pipe; one end of each liquid return transfer pipe forms a second liquid inlet, and the other end forms a second liquid outlet; and the lumen of each liquid return transfer pipe forms a liquid return transfer passage. This allows for a one-to-one connection between the liquid return pipe interface and the server's liquid cooling outlet.

[0011] In one possible implementation, the liquid return transfer pipe system includes a first liquid return main pipe, a first liquid return manifold, and two or more first liquid return branch pipes. The first liquid return manifold has an inlet, two or more outlets, and a first liquid return branch chamber. The inlet of the first liquid return manifold is connected to each outlet of the first liquid return manifold via the first liquid return branch chamber. One pipe port of the first liquid return main pipe forms a second liquid inlet, and another pipe port is connected to the inlet of the first liquid return manifold. One pipe port of each first liquid return branch pipe is connected to an outlet of the first liquid return manifold, and another pipe port forms a second liquid outlet. In this way, a many-to-one transfer between the interface of the liquid return pipe and the liquid cooling outlet of the server can be achieved.

[0012] In one possible implementation, the liquid return transfer pipe system includes a second liquid return main pipe, a second liquid return manifold, and two or more second liquid return branch pipes. The second liquid return manifold has two or more inlets, one outlet, and a second liquid return branch chamber. Each inlet of the second liquid return manifold is connected to the outlet of the second liquid return manifold via the second liquid return branch chamber. One pipe port of each second liquid return branch pipe forms a second liquid inlet, and another pipe port is connected to an inlet of the second liquid return manifold. One pipe port of the second liquid return main pipe is connected to the outlet of the second liquid return manifold, and another pipe port forms a second liquid outlet. In this way, a one-to-many transfer between the interface of the liquid return pipe and the liquid cooling outlet of the server can be achieved.

[0013] In one possible implementation, the liquid separation device includes a box body, which is used to carry the liquid inlet transfer pipe system and the liquid return transfer pipe system. By providing the box body, the liquid inlet transfer pipe system and the liquid return transfer pipe system can be integrated together, which is convenient for installation and can also reduce the risk of leakage.

[0014] For example, the box body is provided with a positioning structure to define the relative position of the liquid inlet transfer pipe system and the box body, and / or to define the relative position of the liquid return transfer pipe system and the box body. This ensures that the positions of the liquid inlet transfer pipe system and / or the liquid return transfer pipe system are relatively fixed, thereby improving the reliability of the pipeline connection.

[0015] For example, the positioning structure may be a positioning hole or a positioning groove formed on the box wall of the box body, which has a simple structure and is easy to set up.

[0016] For example, a fixing member is provided within the box body to restrain the portion of the liquid inlet transfer pipe system and / or the portion of the liquid return transfer pipe system within the box body. A cable tie can be used as the fixing member. This restrains the portion of the liquid inlet transfer pipe system or the liquid return transfer pipe system within the box body, preventing the relevant pipes from shaking within the box body.

[0017] For example, a pressure sensor is installed in the box body to detect the pressure of the liquid inlet transfer pipe system and / or the pressure of the liquid return transfer pipe system. This makes it easier to understand the working conditions of the relevant pipe systems. At the same time, the pressure sensor can be integrated into the box body, making it easier to arrange and install.

[0018] In one possible implementation, the first liquid inlet of the liquid inlet adapter system is connected to the liquid inlet pipeline via a quick-connect fitting; and / or the second liquid outlet of the return liquid adapter system is connected to the return liquid pipeline via a quick-connect fitting. This facilitates assembly.

[0019] In one possible implementation, the cabinet is equipped with two or more liquid dispensing devices, which are arranged at a predetermined distance along the height of the cabinet. The number and arrangement of the liquid dispensing devices can be flexibly arranged based on the heat dissipation requirements of the servers and heat sinks installed in the cabinet.

[0020] A second aspect of an embodiment of the present application provides a server system comprising a cabinet and a server, wherein the server is disposed horizontally within the cabinet, and the server's liquid cooling inlet and liquid cooling outlet are located on a second side of the cabinet. The cabinet is the cabinet provided in the first aspect above, and the first liquid outlet of the cabinet's liquid inlet transfer pipe system is used to communicate with the server's liquid cooling inlet, and the second liquid inlet of the liquid return transfer pipe system is used to communicate with the server's liquid cooling outlet. Thus, by providing a liquid separation device within the cabinet, the liquid cooling line on the first side of the cabinet can be conveniently transferred to the second side of the cabinet to achieve connection with the server's liquid cooling interface, resulting in a simple structure and flexible configuration.

[0028] An embodiment of the present application provides a cabinet and a server system, wherein the server system includes a cabinet and a server arranged in the cabinet. For ease of understanding and concise description, the cabinet and the server system having the cabinet are described below.

[0029] Please refer to Figure 1, Figure 1 A structural diagram of a server system is shown. Figure 1 It only illustrates the relative positional relationship between the components of the server system and does not represent the physical structure of the components.

[0030] In this embodiment, the server system 100 includes a cabinet 10 and a server 30. The cabinet 10 includes a cabinet body 11, which has a storage space for accommodating the server 30. The server 30 is disposed horizontally within the cabinet body 11. In practical applications, the number of servers 30 disposed within the cabinet body 11 may be one or more. If multiple servers 30 are provided, the multiple servers 30 may be arranged along the height of the cabinet body 11. Figure 1 FIG. 2 exemplarily shows a structure in which four servers 30 are provided in the cabinet 11. In other applications, the size of each server 30, the arrangement position of each server 30, etc. can be set according to actual needs.

[0031] In this embodiment, in order to dissipate heat for the server 30 and ensure the working performance of the server 30, the cabinet 10 also includes a liquid cooling pipeline structure to provide liquid cooling medium to the server 30 through the liquid cooling pipeline structure to perform liquid cooling on the server 30.

[0032] Specifically, the liquid cooling pipeline structure may include a liquid inlet pipeline and a liquid return pipeline ( Figure 1 (not shown in FIG). The liquid inlet pipeline is used for the inflow of the liquid cooling medium, and the liquid return pipeline is used for the outflow of the liquid cooling medium. Typically, the liquid inlet pipeline and the liquid return pipeline are arranged on the first side of the cabinet 11.

[0033] The cabinet 10 provided in this embodiment also includes a liquid separation device 20, which is arranged in the cabinet body 11. The liquid separation device 20 is relatively independent of the cabinet body 11. The liquid separation device 20 can be used to transfer the liquid inlet pipeline and the liquid return pipeline to the second side of the cabinet body 11, so as to facilitate the connection with the relevant interfaces of the server 30. In actual applications, the number of liquid separation devices 20 provided in the cabinet body 11 can be one or more. When there are multiple liquid separation devices 20, the multiple liquid separation devices 20 can be arranged at a set distance along the height direction of the cabinet body 11. The specific arrangement of the multiple liquid separation devices 20 in the cabinet body 11 is related to the liquid cooling pipeline connection requirements of the server 30 in the cabinet body 11. For example, Figure 1 In the figure, the liquid separation devices 20 and the servers 30 are alternately arranged. In other embodiments, the arrangement of the liquid separation devices 20 and the servers 30 can be changed as needed.

[0034] Generally, the cabinet body 11 is configured as a rectangular parallelepiped having four side surfaces in the circumferential direction. The first side surface is one of the four side surfaces, and the second side surface is another of the four side surfaces. The back surface of the cabinet body 11 is usually regarded as the first side surface, and the front surface is regarded as the second side surface. Figure 1 What is shown is the front view of the cabinet 11. Here, the front refers to the side of the cabinet 11 facing the user in the use state, and the back refers to the side of the cabinet 11 facing away from the user in the use state.

[0035] The liquid separation device 20 includes a liquid inlet transfer pipe system and a liquid return transfer pipe system ( Figure 1 (not shown in the figure). The liquid inlet transfer pipe system comprises a first liquid inlet, a first liquid outlet, and a liquid inlet transfer passage. The first liquid inlet is connected to the first liquid outlet via the liquid inlet transfer passage. The first liquid inlet is located on the first side of the cabinet 11 and is used to communicate with the liquid inlet pipeline. The first liquid outlet is located on the second side of the cabinet 11 and is used to connect to the heat dissipation element. The liquid return transfer pipe system comprises a second liquid inlet, a second liquid outlet, and a liquid return transfer passage. The second liquid inlet is connected to the second liquid outlet via the liquid return transfer passage. The second liquid inlet is located on the second side of the cabinet 11 and is used to connect to the heat dissipation element. The second liquid outlet is located on the first side of the cabinet 11 and is used to communicate with the liquid return pipeline.

[0036] The liquid separation device 20 may further be provided with a box body, which is used to carry the liquid inlet transfer pipe system and the liquid return transfer pipe system, which is conducive to integrating the liquid separation device 20 into one body and facilitating installation with the cabinet 11.

[0037] After the cabinet 10 provided in this embodiment is applied to the server system 100, the first liquid outlet of the liquid inlet transfer pipe system of the liquid dispensing device 20 can be connected to the liquid cooling inlet of the server 30 located on the front of the cabinet 11, and the second liquid inlet of the liquid return transfer pipe system of the liquid dispensing device 20 can be connected to the liquid cooling outlet of the server 30 located on the front of the cabinet 11. In this way, the liquid cooling medium supplied by the liquid inlet pipeline on the back of the cabinet 11 flows through the liquid inlet transfer pipe system into the liquid cooling-related components (such as cold plates, etc.) in the server 30, carrying the heat generated by the operation of the server 30, and then returns to the liquid return pipeline on the back of the cabinet 11 through the liquid return transfer pipe system, thus forming a cycle to achieve heat dissipation for the server 30. Here, the server 30 is the aforementioned heat-dissipating component.

[0038] By adding the liquid dispensing device 20, the cabinet 10 can conveniently transfer the liquid cooling pipeline on the first side of the cabinet body 11 to the second side of the cabinet body 11 to connect with the server 30 installed in the cabinet 10. The liquid dispensing device 20 has a simple structure and is relatively independent of the cabinet body 11 of the cabinet 10 and the server 30 installed in the cabinet body 11. In actual application, it can be flexibly configured as needed and can be matched with servers 30 of different types and quantities, etc., with wide compatibility. In addition, the liquid dispensing device 20 is relatively independent of the cabinet body 11, and the design of the cabinet body 11 of the cabinet 10 is compatible with liquid cooling and air cooling, with low normalization cost.

[0039] In specific applications, the cabinet 10 can be used to install the server 30, and is also suitable for other heat-dissipating components with heat dissipation requirements. The pipe connection method is similar to the connection method used in the server 30, which can be used as a reference for understanding and will not be repeated here.

[0040] In specific applications, the liquid separation device 20 may have various structural configurations. Several specific implementations of the liquid separation device 20 are described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 2 and Figure 3 , Figure 2 A schematic structural diagram of a liquid separation device in one embodiment is shown; Figure 3 Shown Figure 2 The diagram shows a liquid cooling pipeline connection diagram of the liquid distribution device in the server system.

[0042] To clearly illustrate the pipe connections, Figure 3 The cabinet 11 is not shown, and Figure 3 The sizes and positions of the components in the illustrations may differ from the actual ones. Figure 3 The right side of the center is the back of the cabinet 11, and the left side is the front of the cabinet 11. The liquid inlet pipe 12 and the liquid return pipe 13 are arranged on the back of the cabinet 11. The server 30 of the server system 100 has a liquid cooling inlet 31 and a liquid cooling outlet 32, which are located on the front of the cabinet 11.

[0043] In this embodiment, the liquid separation device 20 includes a box body 21 , a liquid inlet transfer pipe system 22 and a liquid return transfer pipe system 23 . The box body 21 is used to carry the liquid inlet transfer pipe system 22 and the liquid return transfer pipe system 23 .

[0044] The liquid inlet transfer pipe system 22 includes at least one liquid inlet transfer pipe 220. The two pipe ends of this liquid inlet transfer pipe 220 form a first liquid inlet in1 and a first liquid outlet out1, respectively. The pipe end serving as the first liquid inlet in1 is located on the back of the cabinet 11, while the pipe end serving as the first liquid outlet out1 is located on the front of the cabinet 11. The lumen of the liquid inlet transfer pipe 220 forms a liquid inlet transfer passage connecting the first liquid inlet in1 and the first liquid outlet out1. When the liquid inlet transfer pipe system 22 includes more than two liquid inlet transfer pipes 220, each liquid inlet transfer pipe 220 is connected in parallel.

[0045] The liquid return transfer pipe system 23 includes at least one liquid return transfer pipe 230. The two pipe ends of this liquid return transfer pipe 230 form a second liquid inlet in2 and a second liquid outlet out2, respectively. The pipe end serving as the second liquid inlet in2 is located on the front of the cabinet 11, while the pipe end serving as the second liquid outlet out2 is located on the back of the cabinet 11. The lumen of the liquid return transfer pipe 230 forms a liquid return transfer passage connecting the second liquid inlet in2 and the second liquid outlet out2. When the liquid return transfer pipe system 233 includes more than two liquid return transfer pipes 230, each liquid return transfer pipe 230 is connected in parallel.

[0046] The number of the liquid inlet transfer pipes 220 of the liquid inlet transfer pipe system 22 and the number of the liquid return transfer pipes 230 of the liquid return transfer pipe system 23 can be set according to actual application needs and can be one or more. Figure 2 and Figure 3 exemplarily shows a structure in which the liquid inlet transfer pipe system 22 has two liquid inlet transfer pipes 220 and the liquid return transfer pipe system 23 also has two liquid return transfer pipes 230. Accordingly, Figure 3 exemplarily shows a structure in which two servers 30 are provided, and each server 30 has a liquid cooling inlet 31 and a liquid cooling outlet 32 ​​.

[0047] Figure 2 and Figure 3 In the application scenario shown, the liquid cooling requirements of each server 30 in the cabinet 11 are equivalent, and each interface of the liquid inlet pipeline 12 is one-to-one transferred between the liquid cooling inlet 31 of each server 30 through a parallel liquid inlet transfer pipe 220, and each interface of the return liquid pipeline 13 is one-to-one transferred between the liquid cooling outlet 32 ​​of each server 30 through a parallel liquid return transfer pipe 230.

[0048] When the pipes are connected, the first liquid inlet in1 of a liquid inlet transfer pipe 220 is connected to a port on the liquid inlet pipe 12 on the back of the cabinet 11, the first liquid outlet out1 is connected to the liquid cooling inlet 31 of a server 30, the second liquid inlet in2 of a liquid return transfer pipe 230 is connected to the liquid cooling outlet 32 ​​of the server 30, and the second liquid outlet out2 of the liquid return transfer pipe 230 is connected to a port on the liquid return pipe 13 on the back of the cabinet 11. In this way, the liquid coolant flows between the liquid inlet pipe 12, the liquid inlet transfer pipe 220, the server 30, the liquid return transfer pipe 230, and the liquid return pipe 13, achieving heat dissipation for the server 30.

[0049] The connections between another liquid inlet transfer pipe 220 , another server 30 and another liquid return transfer pipe 230 are similar to those described above and will not be repeated.

[0050] During the specific setting, the two pipe ports of the liquid inlet transfer pipe 220 can extend out of the box body 21 to facilitate communication with the interface of the liquid inlet pipeline 12 and the liquid cooling inlet 31 of the server 30. The two pipe ports of the liquid outlet transfer pipe 230 can also extend out of the box body 21 to facilitate communication with the interface of the liquid return pipeline 13 and the liquid cooling outlet 32 ​​of the server 30.

[0051] In actual applications, a cooling liquid distribution unit can be set between the liquid inlet pipe 12 and the liquid return pipe 13 of the cabinet 10 to cool the liquid cooling medium flowing out of the liquid return pipe 13 and then send it into the liquid inlet pipe 12 to form a circulation, thereby achieving continuous heat dissipation of the server 30.

[0052] Figure 3 The combination of solid lines and arrows indicates the pipe connections and flow paths in the liquid inlet direction of the liquid cooling medium, and the combination of dotted lines and arrows indicates the pipe connections and flow paths in the liquid return direction of the liquid cooling medium. The liquid inlet and liquid return here are both based on server 30 as a reference.

[0053] In specific applications, the first liquid inlet in1 of the liquid inlet adapter tube 220 and the interface of the liquid inlet pipeline 12 can be connected by a quick-insert pipe connector. The quick-insert pipe connector includes a male connector and a female connector, one of which can be connected to the first liquid inlet in1 of the liquid inlet adapter tube 220, and the other can be connected to the interface of the liquid inlet pipeline 12. The assembly and disassembly of the liquid inlet adapter tube 220 and the liquid inlet pipeline 12 are realized by the quick plugging or disassembly of the female connector and the male connector, which is fast and reliable. The first liquid outlet out1 of the liquid inlet adapter tube 220 and the liquid cooling inlet 31 of the server 30 can also be connected by a quick-insert pipe connector. In addition to the quick-insert connector connection method, the first liquid inlet in1 of the liquid inlet adapter tube 220 and the interface of the liquid inlet pipeline 12 can also be connected by welding or threaded connection.

[0054] In specific applications, the second liquid inlet in2 of the return liquid transfer pipe 230 and the liquid cooling outlet 32 ​​of the server 30, as well as the second liquid outlet out2 of the return liquid transfer pipe 230 and the interface of the return liquid pipeline 13 can be connected by a quick-connect pipe connector, and can also be connected by welding or threaded connection.

[0055] Please refer to Figure 4 and Figure 5 , Figure 4 A schematic structural diagram of a liquid separation device provided in another embodiment is shown; Figure 5 Shown Figure 4 The figure shows a schematic diagram of the liquid cooling pipeline connection of the liquid distribution device in the server system.

[0056] Similarly, Figure 5 The cabinet 11 is not shown in the figure. Figure 5 The size and position relationship of each component in the figure does not indicate the actual arrangement, but is only for the purpose of clearly illustrating the pipeline connection relationship. Figure 5 The right side of the center is the back of the cabinet 11, and the left side is the front of the cabinet 11. The liquid inlet pipe 12 and the liquid return pipe 13 are arranged on the back of the cabinet 11. The server 30 of the server system 100 has a liquid cooling inlet 31 and a liquid cooling outlet 32, which are located on the front of the cabinet 11.

[0057] In this embodiment, the liquid separation device 20 includes a box body 21 , a liquid inlet transfer pipe system 22 and a liquid return transfer pipe system 23 . The box body 21 is used to carry the liquid inlet transfer pipe system 22 and the liquid return transfer pipe system 23 .

[0058] The liquid inlet transfer pipe system 22 includes a first liquid inlet main pipe 2211, a first liquid inlet manifold 2213 and more than two first liquid inlet branch pipes 2212; the first liquid inlet manifold 2213 has more than two first inlets 2213a, a first outlet 2213b and a first liquid inlet sub-chamber 2213c, and each first inlet 2213a is connected to the first outlet 2213b through the first liquid inlet sub-chamber 2213c; one pipe port of each first liquid inlet branch pipe 2212 forms a first liquid inlet in1, and the other pipe port is connected to a first inlet 2213a of the first liquid inlet manifold 2213; one pipe port of the first liquid inlet main pipe 2211 is connected to the first outlet 2213b of the first liquid inlet manifold 2213, and the other pipe port forms a first liquid outlet out1. After such arrangement, the liquid inlet transfer pipe system 22 has more than two first liquid inlets in1 and one first liquid outlet out1. The liquid cooling medium flowing through the multiple first liquid inlet branch pipes 2212 is gathered through the first liquid inlet manifold 2213 and then flows out through the first liquid inlet main pipe 2211.

[0059] The liquid return transfer pipe system 23 includes a first liquid return main pipe 2311, a first liquid return manifold 2313, and two or more first liquid return branch pipes 2312. The first liquid return manifold 2313 has an inlet 2313a, two or more outlets 2313b, and a first liquid return sub-chamber 2313c. The inlet 2313a of the first liquid return manifold 2313 is connected to each outlet 2313b of the first liquid return manifold 2313 through the first liquid return sub-chamber 2313c. One pipe port of the first liquid return main pipe 2311 forms a second liquid inlet in2, and another pipe port is connected to the inlet 2313a of the first liquid return manifold 2313. One pipe port of each first liquid return branch pipe 2312 is connected to an outlet 2313b of the first liquid return manifold 2313, and the other pipe port forms a second liquid outlet out2. After such arrangement, the liquid return transfer pipe system 23 has a second liquid inlet in2 and two or more second liquid outlets out2. The liquid cooling medium flowing into the first liquid return main pipe 2311 is split through the first liquid return manifold 2313 and then flows out through each first liquid return branch pipe 2312 respectively.

[0060] The number of the first liquid inlet branch pipes 2212 of the liquid inlet transfer pipe system 22 and the number of the first liquid return branch pipes 2312 of the liquid return transfer pipe system 23 can be set according to actual application needs, and can be two, three or more. Figure 4 and Figure 5 The figure shows an exemplary structure in which the liquid inlet transfer pipe system 22 is provided with four first liquid inlet branch pipes 2212 and the liquid return transfer pipe system 23 is also provided with four first liquid return branch pipes 2312. The first liquid inlet manifold 2213 and the first liquid return manifold 2313 can be provided in a matching manner. For example, the first liquid inlet manifold 2213 has four first inlets 2213a, and the first liquid return manifold 2313 has four outlets 2313b. Accordingly, Figure 5 A server 30 is exemplarily shown in FIG. 1 , and the server 30 has a structure of a liquid cooling inlet 31 and a liquid cooling outlet 32 ​​.

[0061] In some embodiments, the number of first inlets 2213a of the first liquid inlet manifold 2213 may not match the number of first liquid inlet branch pipes 2212, but may not be less than the number of first liquid inlet branch pipes 2212. After the pipelines are connected, the first inlets 2213a of the first liquid inlet manifold 2213 not connected to the first liquid inlet branch pipes 2212 can be sealed by plugging or other means. The first liquid return manifold 2313 can also be configured similarly and will not be repeated here.

[0062] When the pipelines are connected, the first liquid inlet in1 of each first liquid inlet branch pipe 2212 is used to communicate with an interface of the liquid inlet pipeline 12 on the back of the cabinet 11, the first liquid outlet out1 of the first liquid inlet main pipe 2211 is used to communicate with the liquid cooling inlet 31 of the server 30, the second liquid inlet in2 of the first liquid return main pipe 2311 is used to communicate with the liquid cooling outlet 32 ​​of the server 30, and the second liquid outlet out2 of each first liquid return branch pipe 2312 is used to communicate with an interface of the liquid return pipeline 13 on the back of the cabinet 11. In this way, the liquid cooling medium flows between the liquid inlet pipeline 12, the liquid inlet transfer pipe system 22 (including the first liquid inlet branch pipe 2212, the first liquid inlet main pipe 2211 and the first liquid inlet manifold 2213), multiple servers 30, the return liquid transfer pipe system 23 (including the first return liquid main pipe 2311, the first return liquid branch pipe 2312 and the first return liquid manifold 2313) and the return liquid pipeline 13, thereby achieving heat dissipation for multiple servers 30.

[0063] In specific applications, a cooling liquid distribution unit can be set between the liquid inlet pipe 12 and the liquid return pipe 13 of the cabinet 10 to cool the liquid cooling medium flowing out of the liquid return pipe 13 and then send it into the liquid inlet pipe 12 to form a circulation, thereby achieving continuous heat dissipation of the server 30.

[0064] During the specific setting, the pipe end of the first liquid inlet main pipe 2211 of the liquid inlet transfer pipe system 22 that forms the first liquid outlet out1 and the pipe end of the first liquid inlet branch pipe 2212 that forms the first liquid inlet in1 can extend out of the box body 21 to facilitate communication with the corresponding pipeline or interface; the pipe end of the first liquid return main pipe 2311 of the liquid return transfer pipe system 23 that forms the second liquid inlet in2 and the pipe end of the first liquid return branch pipe 2312 that forms the second liquid return port out2 can extend out of the box body 21 to facilitate communication with the corresponding pipeline or interface.

[0065] Figure 4 and Figure 5 The solution shown is applicable to application scenarios where the liquid cooling demand for the server 30 is relatively large. The liquid cooling medium flowing out of several interfaces of the liquid inlet pipeline 12 can be collected and used for heat dissipation of one server 30.

[0066] With the aforementioned Figure 3 Similar to the following, Figure 5 The combination of solid lines and arrows is used to indicate the pipe connections and flow paths in the liquid inlet direction of the liquid cooling medium, and the combination of dotted lines and arrows is used to indicate the pipe connections and flow paths in the liquid return direction of the liquid cooling medium. The liquid inlet and liquid return here are both based on server 30 as a reference.

[0067] Similarly, each pipeline connection can also be connected by a quick-insert pipe joint, welding, or threaded connection, which will not be explained one by one.

[0068] Please refer to Figure 6 and Figure 7 , Figure 6 A schematic structural diagram of a liquid separation device provided in yet another embodiment is shown; Figure 7 Shown Figure 6 The figure shows a schematic diagram of the liquid cooling pipeline connection of the liquid distribution device in the server system.

[0069] Figure 7 The cabinet 11 is not shown in the figure. Figure 7 The sizes and positions of the components in the figure do not represent the actual objects, but are only for the purpose of clearly illustrating the piping connection relationships. Figure 7 The right side of the center is the back of the cabinet 11, and the left side is the front of the cabinet 11. The liquid inlet pipe 12 and the liquid return pipe 13 are located on the back of the cabinet 11. The server 30 of the server system 100 has a liquid cooling inlet 31 and a liquid cooling outlet 32, both of which are located on the front of the cabinet 11.

[0070] In this embodiment, the liquid separation device 20 includes a box body 21 , a liquid inlet transfer pipe system 22 and a liquid return transfer pipe system 23 . The box body 21 is used to carry the liquid inlet transfer pipe system 22 and the liquid return transfer pipe system 23 .

[0071] The liquid inlet transfer pipe system 22 includes a second liquid inlet main pipe 2221, a second liquid inlet manifold 2223 and more than two second liquid inlet branch pipes 2222; the second liquid inlet manifold 2223 has a second inlet 2223a, more than two second outlets 2223b and a second liquid inlet sub-chamber 2223c, and the second inlet 2223a is connected to each second outlet 2223b through the second liquid inlet sub-chamber 2223c; one pipe port of the second liquid inlet main pipe 2221 forms a first liquid inlet in1, and the other pipe port is connected to the second inlet 2223a of the second liquid inlet manifold 2223; one pipe port of each second liquid inlet branch pipe 2222 is connected to a second outlet 2223b of the second liquid inlet manifold 2223, and the other pipe port forms a first liquid outlet out1. After such arrangement, the liquid inlet transfer pipe system 22 has a first liquid inlet in1 and two or more first liquid outlets out1. The liquid cooling medium flowing into the second liquid inlet main pipe 2221 is split through the second liquid inlet manifold 2223 and then flows out through each second liquid inlet branch pipe 2222 respectively.

[0072] The liquid return transfer pipe system 23 includes a second liquid return main pipe 2321, a second liquid return manifold 2323, and two or more second liquid return branch pipes 2322; the second liquid return manifold 2323 has two or more inlets 2323a, an outlet 2323b, and a second liquid return sub-chamber 2323c. Each inlet 2323a of the second liquid return manifold 2323 is connected to the outlet 2323b of the second liquid return manifold 2323 through the second liquid return sub-chamber 2323c; one pipe port of each second liquid return branch pipe 2322 forms a second liquid inlet in2, and the other pipe port is connected to an inlet 2323a of the second liquid return manifold 2323; one pipe port of the second liquid return main pipe 2321 is connected to the outlet 2323b of the second liquid return manifold 2323, and the other pipe port forms a second liquid outlet out2. After such arrangement, the liquid return transfer pipe system 23 has more than two second liquid inlets in2 and one second liquid outlet out2. The liquid cooling medium flowing through the plurality of second liquid return branch pipes 2322 is gathered through the second liquid return manifold 2323 and then flows out through the second liquid return main pipe 2321.

[0073] The number of the second liquid inlet branch pipes 2222 of the liquid inlet transfer pipe system 22 and the number of the second liquid return branch pipes 2322 of the liquid return transfer pipe system 23 can be set according to actual application needs, and can be two, three or more. Figure 6 and Figure 7 The figure shows an exemplary structure in which the liquid inlet transfer pipe system 22 is provided with four second liquid inlet branch pipes 2222, and the liquid return transfer pipe system 23 is also provided with four second liquid return branch pipes 2322. The second liquid inlet manifold 2223 and the second liquid return manifold 2323 can be provided in a matching manner. For example, the second liquid inlet manifold 2223 has four second outlets 2223b, and the second liquid return manifold 2323 has four inlets 2323a. Accordingly, Figure 7 exemplarily shows a structure in which four servers 30 are provided, and each server 30 has a liquid cooling inlet 31 and a liquid cooling outlet 32 ​​.

[0074] In some embodiments, the number of second outlets 2223b of the second liquid inlet manifold 2223 may not match the number of second liquid inlet branch pipes 2222, but may not be less than the number of second liquid inlet branch pipes 2222. After the pipelines are connected, the second outlets 2223b of the second liquid inlet manifold 2223 not connected to the second liquid inlet branch pipes 2222 can be sealed using plugs or other means. The second liquid return manifold 2323 can also be configured similarly and will not be repeated here.

[0075] When the pipelines are connected, the first liquid inlet in1 of the second liquid inlet main pipe 2221 is used to connect with an interface of the liquid inlet pipeline 12 on the back of the cabinet 11, the first liquid outlet out1 of each second liquid inlet branch pipe 2222 is used to connect with the liquid cooling inlet 31 of a server 30, the second liquid inlet in2 of a second liquid return branch pipe 2322 is used to connect with the liquid cooling outlet 32 ​​of the server 30, and the second liquid outlet out2 of the second liquid return main pipe 2321 is used to connect with an interface of the liquid return pipeline 13 on the back of the cabinet 11; the connections of the remaining second liquid inlet branch pipes 2222 and the second liquid return branch pipes 2322 are similar. In this way, the liquid cooling medium flows between the liquid inlet pipeline 12, the liquid inlet transfer pipe system 22 (including the second liquid inlet main pipe 2221, the second liquid inlet branch pipe 2222 and the second liquid inlet manifold 2223), multiple servers 30, the return liquid transfer pipe system 23 (including the second return liquid main pipe 2321, the second return liquid branch pipe 2322 and the second return liquid manifold 2323) and the return liquid pipeline 13, thereby achieving heat dissipation for multiple servers 30.

[0076] In specific applications, a cooling liquid distribution unit can be set between the liquid inlet pipe 12 and the liquid return pipe 13 of the cabinet 10 to cool the liquid cooling medium flowing out of the liquid return pipe 13 and then send it into the liquid inlet pipe 12 to form a circulation, thereby achieving continuous heat dissipation of the server 30.

[0077] During the specific setting, the pipe end of the second liquid inlet main pipe 2221 of the liquid inlet transfer pipe system 22 that forms the first liquid inlet in1 and the pipe end of the second liquid inlet branch pipe 2222 that forms the first liquid outlet out1 can be extended out of the box body 21 to facilitate communication with the corresponding pipeline or interface; the pipe end of the second liquid return main pipe 2321 of the liquid return transfer pipe system 23 that forms the second liquid outlet out2 and the pipe end of the second liquid return branch pipe 2322 that forms the second liquid inlet in2 can be extended out of the box body 21 to facilitate communication with the corresponding pipeline or interface.

[0078] Figure 6 and Figure 7 The solution shown is applicable to a scenario where there are fewer interfaces on the liquid inlet pipeline 12 and the liquid return pipeline 13, but there are more servers 30 to be cooled.

[0079] With the aforementioned Figure 3 and Figure 5 Similar to the following, Figure 7 The combination of solid lines and arrows is used to indicate the pipe connections and flow paths in the liquid inlet direction of the liquid cooling medium, and the combination of dotted lines and arrows is used to indicate the pipe connections and flow paths in the liquid return direction of the liquid cooling medium. The liquid inlet and liquid return here are both based on server 30 as a reference.

[0080] Similarly, each pipeline connection can also be connected by a quick-insert pipe interface connection or welding or threaded connection, which will not be explained one by one.

[0081] In the specific embodiments and application scenarios of the above three liquid separation devices 20, the server 30 that needs heat dissipation is illustrated as having only one liquid cooling inlet 31 and one liquid cooling outlet 32. The three implementation methods correspond to one-to-one pipe switching, one-to-many pipe switching, and many-to-one pipe switching, respectively. In actual applications, depending on the different liquid cooling heat dissipation settings inside the server 30, there may be a situation where there are more than two liquid cooling inlets 31 or more than two liquid cooling outlets 32, or there may be a situation where the number of liquid cooling inlets 31 and the number of liquid cooling outlets 32 are different. At this time, the liquid inlet switching pipe system 22 and the liquid return switching pipe system 23 of the liquid separation device 20 can be adaptively set according to needs, for example, Figure 2 The liquid inlet transfer pipe system 22 shown is Figure 4 or Figure 6 The liquid return transfer pipe system 23 shown cooperates to form a new liquid separation device 20.

[0082] In specific applications, as needed, the liquid inlet transfer pipe system 22 of a liquid separation device 20 can also include Figure 2 The transfer pipe system shown and Figure 4 or Figure 6 The transfer pipe system shown is similar to the liquid return transfer pipe system 23. In summary, the liquid separation device 20 provided in the embodiment of the present application is flexible in configuration and can be configured in different ways according to needs, which will not be listed one by one.

[0083] In the above embodiments, the liquid inlet pipe 12 and the liquid return pipe 13 of the cabinet 10 are both disposed on the back of the cabinet 11, and the liquid cooling inlet 31 and the liquid cooling outlet 32 ​​of the server 30 installed in the cabinet 11 are both disposed on the front of the cabinet 11. In some embodiments, the liquid inlet pipe 12 and the liquid return pipe 13 may be disposed on other sides of the cabinet 11, and the liquid cooling inlet 31 and the liquid cooling outlet 32 ​​of the server 30 may also be disposed on other sides of the cabinet 11 different from the liquid inlet pipe 12 and the liquid return pipe 13.

[0084] In the above embodiments, a positioning structure may be provided on the housing 21 of the liquid dispensing device 20 to define the relative positions of the pipes of the liquid inlet transfer pipe system 22 and the housing 21, and / or to define the relative positions of the pipes of the liquid return transfer pipe system 23 and the housing 21. This prevents the relevant pipes from moving relative to the housing 21, thereby improving the reliability of the pipeline connection.

[0085] In a specific application, a plurality of positioning holes 21a can be provided on the box wall 211 of the box body 21. Figure 2 The liquid inlet transfer pipe 220 shown, Figure 4 The first liquid inlet main pipe 2211, the first liquid inlet branch pipe 2212, and Figure 6The second liquid inlet main pipe 2221 and the second liquid inlet branch pipe 2222 shown in the figure can pass through the positioning holes 21a on the box wall 211 at the corresponding positions to define the positions. Figure 2 The liquid return transfer pipe 230 shown, Figure 4 The first liquid return main pipe 2311, the first liquid return branch pipe 2312, and Figure 6 The second liquid return main pipe 2321 and the second liquid return branch pipe 2322 shown in the figure can also pass through the positioning holes 21 on the box wall 211 at the corresponding positions to define the positions. In other words, the positioning structure adopts the form of positioning holes 21a.

[0086] In some embodiments, the positioning structure may also be in the form of a positioning groove provided on the box wall 211. In other embodiments, the positioning structure may also be in the form of a snap-fit ​​groove provided inside the box body 21.

[0087] In the above embodiments, a fixing member 24 (marked on Figure 5 and Figure 7 (In the middle section, the fixing member 24 is used to restrain the inlet and / or return transfer pipes located within the box body. For example, the fixing member 24 can be a cable tie. Thus, if the box body 21 has many or long pipes, the fixing member 24, such as a cable tie, can be used to restrain the pipes, preventing the pipes from shaking and rubbing within the box body 21, which could lead to leakage and other undesirable phenomena.

[0088] In each of the above embodiments, the liquid dispensing device 20 may also include a pressure sensor (not shown) installed within the housing 21. The pressure sensor is used to detect the pressure in the inlet transfer pipe system 22 and / or the return transfer pipe system 23, thereby facilitating monitoring of the operating conditions of the relevant pipe systems and controlling the heat dissipation of the server 30. Furthermore, the pressure sensor can be integrated within the housing 21 for easier layout and installation. The number and location of the pressure sensors can be adjusted based on actual application requirements.

[0089] In the above embodiments, the liquid separation device 20 may also be provided without the box body 21 , and the liquid inlet transfer pipe system 22 and the liquid return transfer pipe system 23 may be directly installed with the cabinet 11 .

[0090] In the above embodiments, the liquid inlet transfer pipe system 22 and the liquid return transfer pipe system 23 of the partitioning device 20 are basically in the form of pipeline structures. In some embodiments, the liquid inlet transfer pipe system 22 and / or the liquid return transfer pipe system 23 can also be in other structural forms, such as a flow channel structure directly formed on the box body 21.

The description of the above examples is only intended to help understand the method and core ideas of this application. It should be noted that for those skilled in the art, without departing from the principles of this application, various improvements and modifications can be made to this application, and such improvements and modifications also fall within the scope of protection of the claims of this application.
