[0040] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0041] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0042] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0043] In the related art, reference Figure 4As shown in the figure, a system structure with a ring network plus an isolation valve is used. The cold source 01 and CDU (Coolant Distribution Unit) 02 are connected by a primary ring network, and CDU02 and cabinet 03 are connected by a secondary ring network. In addition, cabinets 03 in the same group may also be connected to the secondary ring network by a ring network. Each interface of the ring network basically needs to be arranged with a corresponding control valve. If a certain point on the ring network leaks or needs to be repaired, the fault point can be isolated from the system for repair and maintenance by closing the adjacent control valve.

[0044] When this liquid cooling system was first developed, its main goal was to meet the liquid cooling needs of large-scale data centers. It has better and stronger cooling capabilities. Its one-time investment is high and its construction period is long, but it can also give full play to its high energy efficiency characteristics in large-scale data center scenarios.

[0045] However, the above system has the problems of large system granularity, long construction period, large fault domain, and difficult to control construction quality by adopting engineering implementation. Among them, large system granularity means that the coupling between modules is high. The change of one module often needs to involve multiple modules, which increases the maintenance cost of the liquid cooling system. Large fault domain corresponds to the system granularity. The coupling between multiple modules is high. If one module fails, it will affect multiple modules coupled with it, and the scope of failure impact is wider.

[0046] In addition, the above liquid cooling system cannot achieve mixed deployment of air and liquid cooling, and cannot meet the liquid cooling transformation needs of existing computer rooms. The liquid cooling system matched with the ring network has a large capacity of a single system, generally above 8MW. If an extreme fault occurs in a single system, such as a pipe burst or multiple points of failure at the same time, all cabinets supported by the system will be affected, and the fault impact domain is large.

[0047] Therefore, the present application provides a liquid cooling system that does not require a ring network connection. The cold source and cold distribution unit can match one or several cabinets. It has a simple structure, a short construction period, low cost, and reduces the system and fault impact domain.

[0048] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0049] On the one hand, combined with Figure 1 As shown, an embodiment of the present application provides a liquid cooling system, which includes: a first cold source 1, a second cold source 2, a first cold energy distribution unit 3, a second cold energy distribution unit 4 and at least one cabinet 5; the first cold source 1 is connected to the first cold energy distribution unit 3, and the second cold source 2 is connected to the second cold energy distribution unit 4; the first cold energy distribution unit 3 and the second cold energy distribution unit 4 are connected in parallel to at least one cabinet 5.

[0050] The liquid cooling system includes a first working mode, a second working mode and a third working mode.

[0051] In the first working mode, the first cold source 1 and the first cold energy distribution unit 3 work, and the second cold source 2 and the second cold energy distribution unit 4 do not work; in the second working mode, the second cold source 2 and the second cold energy distribution unit 4 work, and the first cold source 1 and the first cold energy distribution unit 3 do not work; in the third working mode, the first cold source 1 and the first cold energy distribution unit 3 work, and the second cold source 2 and the second cold energy distribution unit 4 work at the same time.

[0052] In the liquid cooling system of this embodiment, the cold source, the cold capacity distribution unit and the cabinet 5 are directly connected. The cold capacity provided by the cold source is transmitted to the cabinet 5 through the cold capacity distribution unit without the need for a ring network connection. The cold source and the cold capacity distribution unit can match one or several cabinets 5. The structure is simple, the construction period is short, the cost is low, and it can be applied to small-scale and sporadic liquid cooling scenarios. The cabinet 5 is cooled in parallel by two cold sources and two cold capacity distribution units to form a 2N backup architecture with backup working capability. On the one hand, three different working modes can be realized to meet different cooling requirements. On the other hand, normal cooling of the cabinet 5 can be ensured in the event of a fault.

[0053] In the liquid cooling system of this embodiment, two cold sources and two cold distribution units are connected in parallel to form a 2N backup architecture with the smallest granularity, which is conducive to achieving advantages such as online maintenance of single-point failures and a small impact domain of extreme failures.

[0054] The liquid cooling system of this embodiment has a first working mode, a second working mode and a third working mode, wherein in the first working mode and the second working mode, a cold source and a cold distribution unit work independently, respectively, and in the third working mode, two cold sources and two cold distribution units work simultaneously. The first working mode and the second working mode have better reliability. When a cold source or a cold distribution unit fails or needs maintenance, it can be switched to another working mode without affecting the normal cooling of the cabinet 5. In the third working mode, two cold sources provide cooling at the same time, which can provide a larger cooling capacity for the cabinet 5.

[0055] In some possible implementations, a primary circulation loop is formed between the first cold source 1 and the first cold distribution unit 3, and between the second cold source 2 and the second cold distribution unit 4, in which a primary cooling liquid circulates; a secondary circulation loop is formed between the cold distribution unit and at least one cabinet 5, in which a secondary cooling liquid circulates. Heat is exchanged between the primary cooling liquid and the secondary cooling liquid in the first cold distribution unit 3 and the second cold distribution unit 4 to achieve cold transfer.

[0056] Exemplarily, the primary-side coolant and the secondary-side coolant may have different working fluid requirements due to different working conditions.

[0057] When the liquid cooling system of this embodiment is working, the primary side coolant delivered by the first cold source 1 and the second cold source 2 transfers the cold to the secondary side coolant in the first cold capacity distribution unit 3 and the second cold capacity distribution unit 4 respectively. The secondary side coolants enter different cabinets 5 respectively, absorb heat and heat up in the cabinets 5, and then flow back to the first cold capacity distribution unit 3 and the second cold capacity distribution unit 4 respectively, and then exchange heat with the primary side coolant. The primary side coolant absorbs heat and heats up, and then flows back to the first cold source 1 and the second cold source 2 to cool down, thereby executing the next round of cyclic cooling.

[0058] It should be noted that the "connection" of two components in the present application not only includes the two components being connected together in contact with each other, but also includes the use of a sealed pipeline to connect two components that are not in contact with each other, so that the fluid in one component can enter the other component along the sealed pipeline.

[0059] In some possible implementations, each cabinet 5 is provided with at least one liquid cooling plate, which may be a metal block made of copper, nickel or aluminum, with a circulating flow channel inside, which is connected to the first cooling distribution unit 3 and the second cooling distribution unit 4, and the secondary side cooling liquid flows therein.

[0060] The liquid cooling plate can be in close contact with heat-generating components such as the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) to absorb the heat of the CPU and GPU.

[0061] Exemplarily, the number of liquid cooling plates is, for example, one, two, three, etc., and the number of liquid cooling plates can be reasonably selected according to the number of heat generating components in the cabinet 5. Each liquid cooling plate contacts different heat generating components to cool them down.

[0062] Combination Figure 2 As shown, in some embodiments, at least one cabinet 5 includes a cooling liquid inlet 51 and a cooling liquid outlet 52; the cooling liquid inlet 51 and the cooling liquid outlet 52 are respectively connected to the first cooling distribution unit 3 and the second cooling distribution unit 4 through a three-way component 6.

[0063] Through the above arrangement, the cooling liquid inlet 51 and the cooling liquid outlet 52 of each cabinet 5 can be simultaneously connected to the first cooling distribution unit 3 and the second cooling distribution unit 4 through the three-way assembly 6, which is conducive to realizing multiple working modes in which the two cooling distribution units respectively provide cooling for the cabinets 5, and can also simplify the piping complexity of the liquid cooling system and reduce the construction period and construction difficulty of the liquid cooling system.

[0064] Exemplarily, the cooling liquid inlet 51 of the cabinet 5 is connected to the first cooling distribution unit 3 and the second cooling distribution unit 4 through a tee assembly 6. In another exemplary embodiment, the cooling liquid outlet 52 of the cabinet 5 is connected to the first cooling distribution unit 3 and the second cooling distribution unit 4 through a tee assembly 6. In another exemplary embodiment, the cooling liquid inlet 51 and the cooling liquid outlet 52 of the cabinet 5 are connected to the first cooling distribution unit 3 and the second cooling distribution unit 4 through a tee assembly 6.

[0065] Combination Figure 3 As shown, in some embodiments, the three-way assembly 6 includes a main channel opening 61 and two branch channel openings 62; one main channel opening 61 is used to connect the cooling liquid inlet 51 or the cooling liquid outlet 52 of at least one cabinet 5, and the two branch channel openings 62 are used to connect the first cooling distribution unit 3 and the second cooling distribution unit 4.

[0066] The three-way assembly 6 of this embodiment uses the main channel opening 61 to connect the cooling liquid inlet 51 or the cooling liquid outlet 52 of the cabinet 5, and the two branch channel openings 62 are respectively connected to the first cooling distribution unit 3 and the second cooling distribution unit 4. When the main channel opening 61 is connected to the cooling liquid inlet 51, the secondary cooling liquid transported by the first cooling distribution unit 3 and the second cooling distribution unit enters the three-way assembly 6 through the two branch channel openings 62, enters the cooling liquid inlet 51 through the main channel opening 61 after being collected, and then enters the liquid cooling plate in the cabinet 5 to absorb the heat of the heating components. When the main channel opening 61 is connected to the cooling liquid outlet 52, the secondary cooling liquid that absorbs heat enters the three-way assembly 6 through the cooling liquid outlet 52 through the main channel opening 61, and flows to the first cooling distribution unit 3 and the second cooling distribution unit through the two branch channel openings 62 after being divided, and exchanges heat with the primary cooling liquid in the first cooling distribution unit 3 and the second cooling distribution unit.

[0067] Combination Figure 2 As shown, in some embodiments, both the main channel opening 61 and the branch channel opening 62 are provided with quick connectors 7. In order to reduce the construction difficulty and construction period of the liquid cooling system, the quick connectors 7 are used on the main channel opening 61 and the branch channel opening 62 of the three-way assembly 6, so that the cabinet 5 and the first cold distribution unit 3 and the second cold distribution unit 4 can be quickly and leak-free plugged in. The quick connector 7 can also be a liquid cooling quick plug and a liquid cooling connector, which can realize the rapid connection of the cooling liquid pipeline and has the function of disconnection and self-sealing, which is conducive to improving the rapid deployment capability of the liquid cooling system of this embodiment. When the number of cabinets 5 changes, the cabinet 5 and the cold distribution unit can be quickly connected and disconnected, so that the liquid cooling system has better flexible deployment capability.

[0068] Combination Figure 1 and Figure 2As shown, in some embodiments, each cabinet 5 is connected to the first cooling distribution unit 3 via a first liquid supply pipe 31 and a first liquid return pipe 32, and each cabinet 5 is connected to the second cooling distribution unit 4 via a second liquid supply pipe 41 and a second liquid return pipe 42.

[0069] In the liquid cooling system of this embodiment, the first cooling distribution unit 3 can circulate the secondary cooling liquid into the cabinet 5 by using the first liquid supply pipe 31 and the first liquid return pipe 32, thereby providing a continuous supply of cooling for the cabinet 5. The second cooling distribution unit 4 can circulate the secondary cooling liquid into the cabinet 5 by using the second liquid supply pipe 41 and the second liquid return pipe 42, thereby also providing a continuous supply of cooling for the cabinet 5. The liquid supply and liquid return of the two cooling distribution units are independent of each other, and have better fault compatibility, which greatly reduces the granularity of the impact of extreme faults (such as pipe bursts), and is conducive to shortening the difficulty and time of restoring the cooling capacity after an extreme fault occurs. In this embodiment, the two cooling distribution units and each cabinet 5 are connected in parallel with each other, thereby realizing a 2N backup architecture of the two cooling distribution units.

[0070] In some possible implementations, a primary circulation loop is formed between the first cold source 1 and the first cold capacity distribution unit 3 using the first main liquid supply pipe 11 and the first main liquid return pipe 12, and a primary circulation loop is formed between the second cold source 2 and the second cold capacity distribution unit 4 using the second main liquid supply pipe 21 and the second main liquid return pipe 22.

[0071] Combination Figure 2 As shown, in some embodiments, the first liquid supply pipe 31 and the second liquid supply pipe 41 are connected to a first three-way assembly 601 connected to the coolant inlet 51; the first liquid return pipe 32 and the second liquid return pipe 42 are connected to a second three-way assembly 602 connected to the coolant outlet 52.

[0072] In some embodiments, the first liquid supply pipe 31 and the first liquid return pipe 32 are both connected to the first cooling distribution unit 3 by a clamp, and the second liquid supply pipe 41 and the second liquid return pipe 42 are both connected to the second cooling distribution unit 4 by a clamp; the cooling liquid inlet 51 and the first three-way assembly 601 are connected by a clamp, and the cooling liquid outlet 52 and the second three-way assembly 602 are connected by a clamp; the first liquid supply pipe 31 and the first liquid return pipe 32 are both connected to the first three-way assembly 601 by a quick connector 7, and the second liquid supply pipe 41 and the second liquid return pipe 42 are both connected to the second three-way assembly 602 by a quick connector 7.

[0073] Through the above arrangement, the liquid cooling system of this embodiment uses quick-connect joints 7 at the connection positions of the liquid supply pipe and the liquid return pipe with the three-way assembly 6. When the number of cabinets 5 changes, the cabinets 5 and the cold distribution unit can be quickly connected and disconnected, so that the liquid cooling system has good flexible deployment capabilities. Between the liquid supply pipe and the liquid return pipe and the cold distribution unit, and between the cabinet 5 and the three-way assembly 6, a clamp with high cost performance but greater difficulty in disassembly and assembly is used, which can reduce the cost of the liquid cooling system.

[0074] In some possible implementations, the first liquid supply pipe 31, the first liquid return pipe 32, the second liquid supply pipe 41 and the second liquid return pipe 42 all use EPDM (Ethylene-Propylene-Diene Monomer) hoses, which have better heat resistance, weather resistance and other aging resistance properties, which is beneficial to improving the service life and safety of the liquid cooling system.

[0075] Combination Figure 1 As shown, in some embodiments, the liquid cooling system further includes a first wind wall 8 and a second wind wall 9 , the first wind wall 8 is connected to the first cold source 1 , and the second wind wall 9 is connected to the second cold source 2 .

[0076] Through the above arrangement, the first cold source 1 of this embodiment can supply cold to the first wind wall 8, and the second cold source 2 can supply cold to the second wind wall 9, so that the liquid cooling system of this embodiment has air cooling capability, realizing an air-liquid mixed cooling mode.

[0077] Exemplarily, the first wind wall 8 and the second wind wall 9 are both stacked or installed in rows by multiple fan modules, making the best use of the space, which makes the airflow distribution better and ensures a more uniform airflow through the air cooling terminal, thereby improving the heat transfer performance. After a fan fails, the remaining fans will compensate for the air volume, so the redundancy function improves the operational reliability of the entire system.

[0078] The air wall on the air cooling side and the cooling distribution unit on the liquid cooling side are both connected to the integrated cooling source. This design can support the dynamic adjustment of the air cooling and liquid cooling ratio of the cabinet. It is only necessary for the air wall and cooling distribution unit to control the cooling capacity input by the integrated cooling source respectively.

[0079] Combination Figure 1 As shown, in some embodiments, there are multiple cabinets 5, and the multiple cabinets 5, the first cooling distribution unit 3 and the second cooling distribution unit 4 are arranged in a straight line queue, and the first cooling distribution unit 3 and the second cooling distribution unit 4 are arranged in sequence at the same end of the straight line queue.

[0080] Through the above arrangement, the arrangement difficulty of the cooling liquid pipeline between the first cooling distribution unit 3 and the second cooling distribution unit 4 and the cabinet 5 is reduced, and the cabinet 5 can be flexibly deployed at the other end of the linear queue according to business needs without adjusting the cooling distribution unit.

[0081] In addition, the first cooling distribution unit 3 and the second cooling distribution unit 4 are arranged in the same row as the multiple cabinets 5, so that the first cooling distribution unit 3 and the second cooling distribution unit 4 are deployed close to the heat source (cabinet 5), which is beneficial to improving the heat exchange efficiency of the liquid cooling system.

[0082] In some possible implementations, the first cold source 1 and the second cold source 2 are integrated into one device and arranged on the outdoor side; the first cold distribution unit 3, the second cold distribution unit 4 and at least one cabinet 5 are integrated into another device and arranged on the indoor side; the integrated device is produced and assembled in the factory, delivered as a complete machine, and installed as a whole, which is conducive to realizing standardized production, further simplifying on-site pipeline connections, and simplifying the deployment of power and communication interfaces.

[0083] The liquid cooling system provided in the embodiment of the present application has a simple structure, flexible deployment scale, supports liquid cooling business deployment with a minimum granularity of 500kW, and can adapt to the deployment needs of large-scale liquid cooling business through replication and superposition.

[0084] On the other hand, this embodiment provides a data center, which uses the liquid cooling system of this application. The data center of this embodiment uses the cooling system of this application and has all the beneficial technical effects of all the embodiments herein.

[0085] In some possible implementations, the number of cooling systems used in a data center can be one or more. When multiple cooling systems are used, the liquid cooling plates in the data center are in the form of a ring network, and multiple cooling systems are connected to the liquid cooling ring network in parallel. A water-cooled wind wall is used at the wind side end, and the cooling system and wind wall are in a one-to-many form. Each cooling system corresponds to a certain number of wind walls, which reduces the granularity of wind side faults and improves the reliability of the system.

[0086] In some other possible implementations, the data center further includes at least one server.

[0087] The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The terminal can be a smart phone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, etc., but is not limited to this. The terminal and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in this disclosure.
