[0015] As used herein, "data center" refers to a global collaborative network of characteristic equipment used to transmit, accelerate, display, calculate and store data information on the Internet infrastructure. In recent years, with the rise and development of artificial intelligence, the computing power requirements of IT equipment (such as servers) in data centers have also increased dramatically, resulting in more and more heat generated by server operation. In particular, the power of electronic components involved in AI machine learning (such as graphics processors packaged in servers) has increased from 400W per card to 800W per card. However, some data centers are still using traditional air cooling to dissipate heat from servers, which can no longer meet the heat dissipation requirements of current servers. To this end, an embodiment of the present application provides a liquid cooling system that can meet the heat dissipation requirements of current servers, allowing the server to operate at a relatively suitable temperature.
[0016] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.
[0017] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0018] See also Figures 1 to 3 , Figure 1 is a schematic diagram of the structure of a liquid cooling system 10 provided in an embodiment of the present application, Figure 2 yes Figure 1 A schematic diagram of the structure of the middle cabinet 100, Figure 3 yes Figure 2 Schematic diagram of the cross-sectional structure of the middle cabinet 100 along V-V.
[0019] The liquid cooling system 10 provided in the embodiment of the present application can be used to dissipate heat from servers in a data center to meet the heat dissipation requirements of servers with high computing power in current data centers. Figure 1 As shown, the liquid cooling system 10 may include: a cabinet 100 and a connecting mechanism 200. Among them, the cabinet 100 can be used to accommodate servers, and the connecting mechanism 200 can be connected to multiple cabinets 100. At the same time, the connecting mechanism 200 can supply cooling liquid into the cabinet 100, so as to use the cooling liquid to immerse the server in the cabinet 100 in cooling, so as to meet the cooling requirements of the current server. In addition, since the liquid cooling system 10 can be divided into a cabinet 100 and a connecting mechanism 200, and the connecting mechanism 200 can be connected to multiple cabinets 100, the cabinet 100 and the connecting mechanism 200 have a high degree of freedom in matching. In the early planning of the liquid cooling system 10, the connecting mechanism 200 can be preset to connect to the cabinets 100 exceeding the current required number, so that when the user needs to add a new cabinet 100, the newly added cabinet 100 can be directly connected to the connecting mechanism 200, which is conducive to improving the scalability of the liquid cooling system 10. In the description of the present application, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0020] The cabinet 100 can be used to accommodate servers and be connected to the cooling liquid provided by the connection mechanism 200 to immerse the servers in heat. Figure 1As shown, the number of cabinets 100 can be multiple, and a single cabinet 100 can accommodate only one server. For example, the number of cabinets 100 can be two, and the two cabinets 100 can accommodate two servers respectively. The connecting mechanism 200 can connect the two cabinets 100 at the same time, and supply cooling liquid into the two cabinets 100 to dissipate heat for the two servers in the two cabinets 100 respectively. In this way, the two independent cabinets 100 can maintain the independence of the heat dissipation of the two servers, and can perform targeted heat dissipation on a certain server.
[0021] Optionally, the number of the cabinets 100 may be three, four, five or more, in addition to two, and the multiple cabinets 100 may be arranged in a straight line and located on the same side of the connecting mechanism 200. Of course, the arrangement of the multiple cabinets 100 is not limited, and the specific arrangement and the connection position with the connecting mechanism 200 may also be adaptively adjusted according to different installation sites, which is not limited in this embodiment.
[0022] Through the above settings, when a server generates a high amount of heat when it is fully loaded, the server can be specifically cooled by increasing the flow rate of the coolant in the cabinet 100 containing the server, while the coolant in the cabinet 100 containing other servers will not be affected, so as to improve the heat dissipation effect of the liquid cooling system 10 and reduce the probability of overheating of a server due to full load operation but still cooling with the server that is not fully loaded under the same flow rate of coolant. At the same time, compared with the solution in which the cabinet 100 accommodates multiple servers, the solution in which a single cabinet 100 accommodates only one server only needs to open the corresponding cabinet 100 when maintaining a single server, which can effectively reduce the volatilization of the coolant in the cabinet 100 when maintaining the server, thereby reducing the cost of the liquid cooling system 10 and protecting the atmospheric environment. In addition, a single cabinet 100 accommodates only one server, and the cabinet 100 can also be modularly designed according to the number of servers, enhancing the degree of freedom of coordination between the cabinet 100 and the connecting mechanism 200, thereby improving the scalability of the liquid cooling system 10.
[0023] Optionally, the cabinet 100 may also accommodate multiple servers at the same time, such as two, three, four, five or more servers, and it is only necessary to ensure that the connection mechanism 200 can be connected to the cabinet 100 and that the cooling liquid can be supplied to the cabinet 100. When the cabinet 100 accommodates multiple servers, in order to maintain the heat dissipation independence of the multiple servers, the cabinet 100 may be preset with the same number of installation cavities as the servers and independent of each other, and the multiple installation cavities can be independently connected to the cooling liquid supplied by the connection mechanism 200, so as to maintain the heat dissipation independence of the multiple servers by using the independent installation cavities.
[0024] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.
[0025] Since the structures of the multiple cabinets 100 may be the same or similar, the following description will be made taking the structure of a single cabinet 100 as an example. Figures 2 to 3 As shown, the cabinet 100 may include: a cover 110 and a box body 120. The cover 110 may be covered on the open side of the box body 120, and together with the box body 120, a receiving cavity 101 may be formed, and the receiving cavity 101 may be used to install a server. At the same time, the cover 110 may be hinged to the box body 120, so that the cover 110 may be flipped relative to the box body 120 to open or close the cover 110. For example, the cover 110 and the box body 120 may be connected by a rotating shaft that passes through both at the same time, so that the cover 110 may be flipped relative to the box body 120. Of course, there may be a variety of ways to connect the cover 110 and the box body 120. In addition to the aforementioned method of using a rotating shaft, the cover 110 and the box body 120 may also be detachably connected by means such as screws or buckles, and this embodiment does not limit this.
[0026] Optionally, in order to improve the sealing performance of the accommodating chamber 101, a sealing gasket (not shown) may be provided between the cover 110 and the box body 120. When the cover 110 is closed, the cover 110 and the box body 120 may clamp the sealing gasket together, and deform the sealing gasket to press against the cover 110 and the box body 120 respectively, so as to absorb the assembly gap between the cover 110 and the box body 120 by using the sealing gasket, thereby improving the sealing performance of the accommodating chamber 101. Of course, in addition to the use of the sealing gasket, the cover 110 and the box body 120 may also be sealed by other optional sealing methods, which is not limited in this embodiment.
[0027] The cover 110 may further include: a connecting portion 111 and a light-transmitting portion 112. Figures 2 to 3As shown, the connection part 111 can be arranged around the periphery of the light-transmitting part 112, and the connection part 111 can be hinged with the box body 120, and drive the light-transmitting part 112 to flip relative to the box body 120. The light-transmitting part 112 can be made of transparent materials such as glass, so that the user can observe the status of the server in the accommodating cavity 101 through the light-transmitting part 112. Optionally, the connection part 111 and the light-transmitting part 112 can be assembled by connection methods such as bonding, welding and fusion. Or, the connection part 111 can also be made of glass, and it can be integrally formed with the light-transmitting part 112.
[0028] The box body 120 may include a bottom wall 121 and a side wall 122. Figures 2 to 3 As shown, the bottom wall 121 can be covered on one side of the side wall 122, the cover body 110 can be covered on the other opposite side of the side wall 122, and the three can be together to form the aforementioned accommodating chamber 101. At the same time, two symmetrically arranged load-bearing parts 1211 can be provided on the side of the bottom wall 121 away from the side wall 122, and the two load-bearing parts 1211 can be respectively located at the edge positions of the opposite sides of the bottom wall 121, and the box body 120 can be placed on the ground or a platform through the load-bearing parts 1211. In addition, the side wall 122 is also provided with two symmetrical bearing racks 1221 in the accommodating chamber 101, and the two bearing racks 1221 can be arranged close to the cover body 110, and both can be used to carry and fix the server installed in the accommodating chamber 101.
[0029] Optionally, the number of the load-bearing part 1211 and the load-bearing frame 1221 may not be limited to two, and the number of the two may be increased or decreased according to design requirements, such as one, three or four. At the same time, the design positions of the load-bearing part 1211 and the load-bearing frame 1221 may also be adaptively adjusted according to the installation site of the liquid cooling system 10 and the structure of the server. Alternatively, the design of the load-bearing part 1211 and the load-bearing frame 1221 may also be omitted.
[0030] In order to cooperate with the connection mechanism 200 to access the cooling liquid, the cabinet 100 may also be provided with an interface 102 connected to the connection mechanism 200. Figures 2 to 3As shown, the interface 102 may include: a liquid inlet 1021 and a liquid return port 1022. The liquid inlet 1021 may be provided on the side wall 122 and communicate with the accommodating chamber 101, and the liquid inlet 1021 may also be connected to the connecting mechanism 200, so that the connecting mechanism 200 can supply cooling liquid into the accommodating chamber 101 through the liquid inlet 1021. The liquid return port 1022 may also be provided on the side wall 122 and communicate with the accommodating chamber 101, and the liquid return port 1022 may also be connected to the connecting mechanism 200, so that the connecting mechanism 200 can recover cooling liquid from the accommodating chamber 101 through the liquid return port 1022. At the same time, since the density of the coolant decreases after the temperature rises during heat exchange with the server, in order to allow the coolant with increased temperature to be recovered through the liquid return port 1022, the liquid inlet 1021 can be set at the bottom of the box body 120 (the area away from the cover body 110), and the liquid return port 1022 can be set at the top of the box body 120 (the area close to the cover body 110), so that the coolant circulates in the accommodating cavity 101 to achieve immersion heat dissipation of the server. In addition, the liquid inlet 1021 and the liquid return port 1022 can also be located on the same side of the side wall 122, so that the liquid inlet 1021 and the liquid return port 1022 are connected to the connection mechanism 200 at the same time.
[0031] Furthermore, in order to facilitate the maintenance of the server, the interface 102 may also include: a drain port 1023. The drain port 1023 may also be provided on the side wall 122 and communicate with the accommodating chamber 101, and the drain port 1023 may also be connected to the connecting mechanism 200, so that the connecting mechanism 200 can discharge the coolant from the accommodating chamber 101 through the drain port 1023 for storage, so that the user can maintain the server in the accommodating chamber 101. At the same time, the drain port 1023 may also be provided on the same side of the side wall 122 as the liquid inlet 1021 and the liquid return port 1022, so that the three can be connected to the connecting mechanism 200 at the same time. In addition, the drain port 1023 may also be provided close to the bottom wall 121, so that the coolant in the accommodating chamber 101 can be discharged through the drain port 1023, thereby reducing the coolant residue in the accommodating chamber 101.
[0032] Furthermore, in order to improve the heat dissipation effect of the liquid cooling system 10, the cabinet 100 may also be provided with a flow balancing plate 130. Figure 3As shown, the flow balancing plate 130 can be arranged in the accommodating chamber 101, and the side of the flow balancing plate 130 facing away from the cover body 110 can be enclosed together with the bottom wall 121 and part of the side wall 122 to form a first accommodating chamber 1011, and the side of the flow balancing plate 130 facing the cover body 110 can be enclosed together with the cover body 110 and part of the side wall 122 to form a second accommodating chamber 1012. That is, the flow balancing plate 130 can divide the accommodating chamber 1011 into the first accommodating chamber 1011 and the second accommodating chamber 1012, and the liquid inlet 1021 can be connected to the first accommodating chamber 1011, and the liquid return port 1022 and the liquid discharge port 1023 can both be connected to the second accommodating chamber 1012. At the same time, the flow equalizer 130 can also be arranged near the liquid inlet 1021, which can make the coolant supplied from the liquid inlet 1021 to the first accommodating chamber 1011 flow more evenly into the second accommodating chamber 1012, so as to evenly dissipate heat for the server placed in the second accommodating chamber 1012, and reduce the probability of local overheating of the server due to uneven flow of coolant. The specific structure and functional principle of the flow equalizer 130 can refer to the prior art, and this embodiment will not be repeated here. Optionally, the drain port 1023 can also be connected to the first accommodating chamber 1011.
[0033] The terms "first", "second", and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features.
[0034] See also Figures 4 to 6 , Figure 4 yes Figure 1 A partial structural diagram of the connecting mechanism 200, Figure 5 yes Figure 1 A schematic diagram of a partial cross-sectional structure of the middle connection mechanism 200 along VI-VI, Figure 6 yes Figure 1 Schematic diagram of the partial cross-sectional structure of the middle connecting mechanism 200 along line VII-VII.
[0035] The connection mechanism 200 can be connected to multiple cabinets 100, and the connection mechanism 200 can also supply cooling liquid into the cabinet 100 to use the cooling liquid to immerse the server in cooling. The following is a specific description of the connection mechanism 200 connected to a single cabinet 100. Figures 4 to 6As shown, the connection mechanism 200 may include: a pipe assembly 210 and an installation cabinet 220. The pipe assembly 210 may be connected to the liquid inlet 1021, the liquid return port 1022, and the liquid discharge port 1023, respectively, and the pipe assembly 210 may not only use the liquid inlet 1021 to supply cooling liquid into the first accommodating chamber 1011, but also use the liquid return port 1022 to recover cooling liquid from the second accommodating chamber 1012, so as to realize the circulation of cooling liquid in the cabinet 100. At the same time, the pipe assembly 210 may also use the liquid discharge port 1023 to discharge cooling liquid from the first accommodating chamber 1011 and the second accommodating chamber 1012, so as to facilitate the user to maintain the server in the cabinet 100.
[0036] Specifically, the pipeline assembly 210 may include: a liquid supply pipeline 211, a liquid return pipeline 212, and a liquid discharge pipeline 213. The liquid supply pipeline 211 may be connected to the liquid inlet 1021, and the liquid return pipeline 212 may supply cooling liquid into the first accommodating chamber 1011 through the liquid inlet 1021. The liquid return pipeline 212 may be connected to the liquid return port 1022, and the cooling liquid may be recovered from the second accommodating chamber 1012 through the liquid return port 1022. The liquid discharge pipeline 213 may be connected to the liquid discharge port 1023, and the cooling liquid may be discharged from the first accommodating chamber 1011 and the second accommodating chamber 1012 through the liquid discharge port 1023. In this way, the pipeline assembly 210 may not only realize the circulation of cooling liquid through the liquid supply pipeline 211 and the liquid return pipeline 212, but also independently discharge cooling liquid for storage through the liquid discharge pipeline 213.
[0037] Optionally, in order to realize the flow of the cooling liquid, at least one of the liquid supply pipeline 211 and the liquid return pipeline 212 may also be connected to a water pump, so as to use the water pump to drive the cooling liquid to flow in the liquid supply pipeline 211 and the liquid return pipeline 212. Similarly, the liquid discharge pipeline 213 may also be independently connected to a water pump, so that the liquid discharge pipeline 213 can discharge the cooling liquid in the cabinet 100 through the water pump. At the same time, at least one of the liquid supply pipeline 211 and the liquid return pipeline 212 may also be connected to a heat exchange unit for heat exchange with the recovered high-temperature cooling liquid, so that the cooling liquid is cooled for secondary circulation. Among them, the water pump and the heat exchange unit may be independent of the liquid cooling system 10, that is, the water pump and the heat exchange unit may also belong to other equipment outside the liquid cooling system 10, and the liquid cooling system 10 may only include the cabinet 100 and the connecting mechanism 200. Of course, in some embodiments, the liquid cooling system 10 may also include a water pump and a heat exchange unit, which is not limited in this embodiment.
[0038] The liquid supply pipeline 211 may be connected to the liquid inlet 1021, and the cooling liquid may be supplied into the first accommodation chamber 1011 through the liquid inlet 1021. Figures 4 to 6As shown, the liquid supply pipeline 211 may include: a liquid supply main pipe 2111 and a liquid supply branch pipe 2112. The liquid supply main pipe 2111 may be connected to a water pump through an external pipeline, and may be used to supply coolant. The liquid supply branch pipe 2112 may be connected to the liquid supply main pipe 2111 and the liquid inlet 1021, respectively, and may transfer the coolant in the liquid supply main pipe 2111 to the liquid inlet 1021, and supply the coolant to the first accommodating chamber 1011 through the liquid inlet 1021. At the same time, the liquid supply main pipe 2111 may be connected to an external pipeline through a sleeve connection or a flange connection, and the liquid supply branch pipe 2112 may also be connected to the liquid inlet 1021 through a sleeve connection or a flange connection. In addition, the liquid supply main pipe 2111 and the liquid supply branch pipe 2112 can be an integral structure, and the two can be integrally formed through processes such as hot pressing, injection molding and stamping to improve the overall sealing of the liquid supply pipeline 211 and reduce the probability of coolant leakage.
[0039] Optionally, the connection mode between the liquid supply main pipe 2111 and the external pipeline, and the connection mode between the liquid supply branch pipe 2112 and the liquid inlet 1021 may also be not limited to the sleeve connection and the flange connection. The specific connection mode may be adaptively adjusted according to the design requirements and is not limited here. At the same time, the liquid supply main pipe 2111 may also be directly connected to the water pump, rather than being connected to the water pump through the external pipeline.
[0040] In the above manner, when the connection mechanism 200 is connected to multiple cabinets 100 at the same time, the liquid supply pipeline 211 can be preset with multiple liquid supply branches 2112 in the early planning, and the number of liquid supply branches 2112 can be more than the number of cabinets 100. Among them, multiple cabinets 100 can be connected with liquid supply branches 2112 that match their number to access the cooling liquid supplied by the liquid supply branches 2112, and the remaining liquid supply branches 2112 can be in a closed state and used as an expansion dock. In this way, when the user needs to add a new cabinet 100, the liquid inlet 1021 of the newly added cabinet 100 can be directly connected to the remaining liquid supply branches 2112, which is conducive to improving the scalability of the liquid cooling system 10.
[0041] The liquid return pipe 212 may be connected to the liquid return port 1022, and the cooling liquid may be recovered from the second accommodating chamber 1012 through the liquid return port 1022. Figures 4 to 6As shown, the liquid return pipeline 212 may include: a liquid return main pipe 2121 and a liquid return branch pipe 2122. Among them, the liquid return main pipe 2121 can be connected to a water pump through an external pipeline, which can be used to recover the coolant. The liquid return branch pipe 2122 can be connected to the liquid return main pipe 2121 and the liquid return port 1022 respectively, and can transfer the high-temperature coolant in the second accommodating chamber 1012 to the liquid return main pipe 2121 for recovery. At the same time, the liquid return main pipe 2121 can be connected to the external pipeline through a sleeve connection or a flange connection, and the liquid return branch pipe 2122 can also be connected to the liquid return port 1022 through a sleeve connection or a flange connection. In addition, the liquid return main pipe 2121 and the liquid return branch pipe 2122 can be an integral structure, and the two can be integrally formed by processes such as hot pressing molding, injection molding, and stamping molding to improve the overall sealing of the liquid return pipeline 212 and reduce the probability of coolant leakage.
[0042] Optionally, the connection method between the liquid return main pipe 2121 and the external pipeline, and the connection method between the liquid return branch pipe 2122 and the liquid return port 1022 may not be limited to the sleeve connection and the flange connection. The specific connection method can be adaptively adjusted according to the design requirements and is not limited here. At the same time, the liquid return main pipe 2121 can also be directly connected to the water pump, rather than being connected to the water pump through an external pipeline.
[0043] In the above manner, when the connection mechanism 200 is connected to multiple cabinets 100 at the same time, the return liquid pipeline 212 can be preset with multiple return liquid branches 2122 in the early planning, and the number of return liquid branches 2122 can be more than the number of cabinets 100, and match the number of liquid supply branches 2112. Among them, multiple cabinets 100 can be connected with return liquid branches 2122 that match their number, so that the cooling liquid in multiple cabinets 100 can be transmitted to the return liquid main pipe 2121 through the return liquid branch 2122 for recycling, and the remaining return liquid branch 2122 can be in a closed state and used as an expansion dock. In this way, when the user needs to add a new cabinet 100, the return liquid port 1022 of the newly added cabinet 100 can be directly connected to the remaining return liquid branch 2122, which is conducive to improving the scalability of the liquid cooling system 10.
[0044] The drain pipe 213 may be connected to the drain port 1023, and the coolant may be discharged from the first accommodating chamber 1011 and the second accommodating chamber 1012 through the drain port 1023. Figures 4 to 6As shown, the drain pipeline 213 may include: a drain main pipe 2131 and a drain branch pipe 2132. Among them, the drain main pipe 2131 can be connected to a storage unit for storing coolant through an external pipeline, which can be used to discharge the coolant. The drain branch pipe 2132 can be connected to the drain main pipe 2131 and the drain port 1023 respectively, which can transfer the coolant in the first accommodating chamber 1011 and the second accommodating chamber 1012 to the drain main pipe 2131 for discharge. At the same time, the drain main pipe 2131 can be connected to the external pipeline by means of a sleeve connection or a flange connection, and the drain branch pipe 2132 can also be connected to the drain port 1023 by means of a sleeve connection or a flange connection. In addition, the drain main pipe 2131 and the drain branch pipe 2132 can be an integral structure, and the two can be integrally formed by processes such as hot pressing molding, injection molding, and stamping molding to improve the overall sealing of the drain pipeline 213 and reduce the probability of coolant leakage.
[0045] Optionally, the connection mode between the drainage main pipe 2131 and the external pipeline, and the connection mode between the drainage branch pipe 2132 and the drainage port 1023 may not be limited to the sleeve connection and the flange connection. The specific connection mode may be adaptively adjusted according to the design requirements and is not limited here. At the same time, the drainage main pipe 2131 may also be directly connected to the water pump, rather than being connected to the water pump through the external pipeline.
[0046] In the above manner, when the connection mechanism 200 is connected to multiple cabinets 100 at the same time, the drain pipeline 213 can be preset with multiple drain branches 2132 in the early planning, and the number of drain branches 2132 can be more than the number of cabinets 100, and match the number of supply branches 2112. Among them, multiple cabinets 100 can be connected with drain branches 2132 that match their number, so that the cooling liquid in multiple cabinets 100 can be transmitted to the drain main pipe 2131 through the drain branch 2132 for discharge, and the remaining drain branch 2132 can be in a closed state and used as an expansion dock. In this way, when the user needs to add a new cabinet 100, the drain port 1023 of the newly added cabinet 100 can be directly connected to the remaining drain branch 2132, which is conducive to improving the scalability of the liquid cooling system 10.
[0047] Furthermore, in order to be able to perform targeted heat dissipation on the servers in a single cabinet 100, the pipeline assembly 210 may also include: a valve 214. The liquid supply pipeline 211, the liquid return pipeline 212, and the liquid discharge pipeline 213 may all be provided with a valve 214, and the valve 214 controls the flow of the coolant in the liquid supply pipeline 211, the liquid return pipeline 212, and the liquid discharge pipeline 213, so as to perform targeted heat dissipation on the servers in a single cabinet 100. For example, the end of the liquid supply branch pipe 2112 connected to the liquid inlet 1021 may be provided with a valve 214, the end of the liquid return branch pipe 2122 connected to the liquid return port 1022 may be provided with a valve 214, and the end of the liquid discharge branch pipe 2132 connected to the liquid discharge port 1023 may be provided with a valve 214. Preferably, the valve 214 may be an electric valve, so that the liquid cooling system 10 can automatically control the flow of the coolant.
[0048] Optionally, in addition to being able to connect cabinets 100 that exceed the current required number by presetting the connection mechanism 200, the scalability of the liquid cooling system 10 can also be improved by setting multiple connection mechanisms 200 to avoid the volume of a single connection mechanism 200 exceeding the limit due to too many expansion positions designed. For example, two connection mechanisms 200 can be preset in the early planning, and the pipeline components 210 in the two connection mechanisms 200 can be connected, that is, the liquid supply main pipe 2111, the liquid return main pipe 2121 and the liquid discharge main pipe 2131 in the two connection mechanisms 200 can be connected by means such as sleeve connection or flange connection. In this way, when the user needs to add a cabinet 100 and the expansion position of one connection mechanism 200 is already occupied, the newly added cabinet 100 can be directly connected to another connection mechanism 200 to improve the scalability of the liquid cooling system 10. Optionally, the number of connection mechanisms 200 is not limited to two, and the number can also be three, four, five or more.
[0049] The installation cabinet 220 can be used to install the pipeline assembly 210 to protect the pipeline assembly 210. Figures 4 to 6 As shown, the installation cabinet 220 can be an open structure, so that the liquid supply pipeline 211, the liquid return pipeline 212 and the liquid discharge pipeline 213 arranged in the installation cabinet 220 can be exposed through the opening 221 on one side of the installation cabinet 220, so that the liquid supply branch pipe 2112, the liquid return branch pipe 2122 and the liquid discharge branch pipe 2132 can be connected to the liquid inlet 1021, the liquid return port 1022 and the liquid discharge port 1023 through the opening 221. In this embodiment, when the connecting mechanism 200 connects multiple cabinets 100, the multiple cabinets 100 can be located on the side of the installation cabinet 220 where the opening 221 is located, so that the multiple cabinets 100 can be connected to the pipeline assembly 210 located in the installation cabinet 220. Optionally, in order to save production costs, the installation cabinet 220 can also be omitted.
[0050] The liquid cooling system 10 provided in the embodiment of the present application can supply cooling liquid into the cabinet 100 by setting a liquid supply pipeline 211, and the return liquid pipeline 212 can recover cooling liquid from the cabinet 100, so that the cooling liquid can circulate in the cabinet 100 to immerse the server in the cabinet 100 in heat dissipation, thereby meeting the heat dissipation requirements of the current high-computing power server. At the same time, by splitting the liquid cooling system 10 into a cabinet 100 and a connecting mechanism 200, and the cabinet 100 only accommodates one server, and the connecting mechanism 200 can connect multiple cabinets 100, the cabinet 100 can be modularized according to the number of servers to enhance the coordination freedom of the cabinet 100 and the connecting mechanism 200. In this way, in the early planning of the liquid cooling system 10, it can be preset that the connecting mechanism 200 can be connected to the cabinet 100 exceeding the current required number, so that when the user needs to add a new cabinet 100, the newly added cabinet 100 can be directly connected to the connecting mechanism 200 to improve the scalability of the liquid cooling system 10.
[0051] See also Figure 7 , Figure 7 Schematic diagram of the structure of the liquid cooling system 10 provided in the embodiment of the present application. The following is a detailed description of the working process of the liquid cooling system 10 provided in the embodiment of the present application.
[0052] like Figure 7 As shown, when the liquid cooling system 10 starts to operate, the valves 214 on the liquid supply branch pipe 2112 and the liquid return branch pipe 2122 are opened, and the valve on the liquid discharge branch pipe 2132 is closed. At this time, the low-temperature coolant can be transmitted through the liquid supply main pipe 2111 under the action of the water pump, and supplied from the liquid inlet 1021 of the cabinet 100 to the first accommodating chamber 1011 through each liquid supply branch pipe 2112. Correspondingly, the coolant entering the first accommodating chamber 1011 can flow evenly to the second accommodating chamber 1012 under the action of the flow equalizing plate 130, and perform heat exchange with the server in the second accommodating chamber 1012 to dissipate heat from the server.
[0053] Furthermore, when the temperature of the coolant increases after heat exchange with the server, the high-temperature coolant can be transmitted to the liquid return branch pipe 2122 through the liquid return port 1022, and transmitted to the liquid return main pipe 2121 through the liquid return branch pipe 2122 for delivery and recovery. In this way, the circulation of the coolant in the cabinet 100 can be achieved to meet the heat dissipation requirements of the current high-computing power servers. In this process, if the operating power of the servers in multiple cabinets 100 is different, the flow rate of the coolant in the multiple cabinets 100 can be changed by adjusting the valves 214 on the liquid supply branch pipe 2112 and the liquid return branch pipe 2122, so as to carry out targeted heat dissipation for the servers in different cabinets 100 and meet the heat dissipation requirements of the servers in different cabinets 100.
[0054] When the user needs to maintain a server in a cabinet 100, the valve 214 on the liquid supply branch pipe 2112 and the liquid return branch pipe 2122 connected to the cabinet 100 can be closed, and the valve 214 on the liquid drain branch pipe 2132 connected to the cabinet 100 can be opened, so that the coolant in the cabinet 100 can be transferred to the liquid drain branch pipe 2132 through the liquid drain port 1023, and then transferred to the liquid drain main pipe 2131 through the liquid drain branch pipe 2132 for discharge and storage. In this way, the user can maintain the server in the cabinet 100 after the coolant in the cabinet 100 is discharged.
[0055] The liquid cooling system 10 provided in the embodiment of the present application is connected to the interface 102 of the cabinet 100 by setting the pipe assembly 210 of the connecting mechanism 200, and the pipe assembly 210 can supply cooling liquid into the cabinet 100, so that the cooling liquid can immerse the server in the cabinet 100 to improve the cooling effect of the server. At the same time, since the liquid cooling system 10 can be divided into a cabinet 100 and a connecting mechanism 200, and the connecting mechanism 200 can be connected to multiple cabinets 100, the cabinet 100 and the connecting mechanism 200 have a high degree of freedom in matching. In the early planning of the liquid cooling system 10, it can be preset that the connecting mechanism 200 can be connected to the cabinets 100 exceeding the current required number, so that when the user needs to add a new cabinet 100, the newly added cabinet 100 can be directly connected to the connecting mechanism 200, which is conducive to improving the scalability of the liquid cooling system 10.

Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
