[0045] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0046] It should be noted that the terms "first", "second" etc. in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable in appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or modules is not necessarily limited to those steps or modules clearly listed, but may include other steps or modules that are not clearly listed or that are inherent to these processes, methods, products or equipment.

[0047] Figure 1 FIG. 1 is a structural diagram of a centralized cooling system for an immersion server cabinet provided by an embodiment of the present application. Figure 1 As shown, the centralized cooling system for immersion server cabinets includes: a server cabinet, a plurality of cooling boxes 10 and a single server in a server cabinet arranged in each of the cooling boxes 10 .

[0048] The server cabinet is provided with:

[0049] Multiple groups of single-server intelligent heat exchange systems 20 corresponding to the multiple single servers are used to store coolant so as to supply the coolant to the heat dissipation boxes 10 of the single servers to regulate the heat dissipation of the single servers when the chassis ambient temperature of the single servers exceeds the target ambient temperature threshold;

[0050] The whole cabinet intelligent exchange system 30 is used to store coolant so that when the coolant in the single-server intelligent heat exchange system is empty or the heat dissipation box is filled with coolant, but the chassis ambient temperature of the single server exceeds the target working environment temperature threshold, the coolant is supplied to the heat dissipation box 10 of the single server to regulate the heat dissipation of the single server.

[0051] In this embodiment, to ensure the normal operation of each single server, the chassis environment temperature of the single server is divided into the following five temperature ranges based on the impact of temperature on the single server:

[0052] [-∞,A],[A,B],[B,C],[C,D],[D,+∞]

[0053] Among them, the ambient temperature threshold A is the minimum ambient temperature for normal operation of each single server, the temperature intervals [A, B] and [C, D] are the normal temperature ranges of each single server, the temperature interval [B, C] is the optimal operating temperature range for efficient operation of the server, and the ambient temperature threshold D is the maximum ambient temperature for normal operation of each single server. Among them, when each single server is above the ambient temperature D for a long time, the server is likely to be damaged. In this embodiment, the target working ambient temperature threshold is set to C. When the chassis ambient temperature exceeds the target working ambient temperature threshold C, heat dissipation control is performed to ensure the normal operation of each single server.

[0054] Specifically, the entire server cabinet is in the shape of a rectangular parallelepiped. The upper part of the rear part of the entire server cabinet is paved with a cold fluid supply loop pipe network and a return fluid supply loop pipe network. The side position of the heat dissipation box 10 is provided with an installation and fixing structure of the cold fluid supply loop pipe network and an installation and fixing structure of the return fluid supply loop pipe network. The cold fluid supply loop pipe network, the return fluid supply loop pipe network, multiple heat dissipation boxes 10 and multiple groups of single-server intelligent heat exchange systems 20 form multiple groups of heat dissipation circuits. The coolant stored in the single-server intelligent heat exchange system 20 in each group of heat dissipation circuits flows into the heat dissipation box 10 of the group through the cold fluid supply loop pipe network. The coolant immerses the server chassis in the heat dissipation box 10, takes away the heat of the single server in the server chassis, and the coolant after heat dissipation exchange with the server chassis flows back to the single-server intelligent heat exchange system 20 through the return fluid supply loop pipe network.

[0055] Furthermore, in this embodiment, the coolant is a liquid with the characteristics of a high-efficiency phase change material, which has good thermal conductivity. When it undergoes phase change, it is accompanied by a large amount of heat absorption and has high heat dissipation efficiency. Therefore, in this embodiment, a heating element is also provided at the bottom of the server chassis. While the coolant immerses the server chassis in the heat dissipation box 10, the coolant undergoes a phase change reaction with the heating element at the bottom of the server chassis. The liquid absorbs heat and vaporizes. When the material changes from liquid to gas, it absorbs a large amount of heat and takes away excess heat from the heating element, thereby achieving the purpose of further heat dissipation and cooling of the single server.

[0056] In addition, in this embodiment, the whole cabinet intelligent switching system 30 also forms multiple heat dissipation circuits through the cold fluid supply loop pipeline network, the return fluid supply loop pipeline network and multiple heat sinks 10. When the coolant in the single-server intelligent heat exchange system 20 is empty or the heat sink 10 is filled with coolant, but the chassis ambient temperature of the single server exceeds the target working environment temperature threshold, the coolant in the whole cabinet intelligent switching system 30 flows into the heat sink 10 of the single server that exceeds the target working environment temperature threshold through the cold fluid supply loop pipeline network. The coolant immerses the server chassis in the heat sink 10, takes away the heat of the single server in the server chassis, and the coolant after heat exchange with the server chassis flows back to the whole cabinet intelligent switching system 30 through the return fluid supply loop pipeline network.

[0057] In addition, it should be noted that in this embodiment, after the entire server cabinet starts to operate, each group of single-server intelligent heat exchange systems 20 enters its own independent heat dissipation determination logic state. Specifically, the chassis ambient temperature of the single server is continuously detected at preset intervals, and it is determined whether the chassis ambient temperature of the single server exceeds the target ambient temperature threshold C. If it exceeds, the coolant is supplied to the heat dissipation box 10 of the single server to regulate the heat dissipation of the single server. Furthermore, in this embodiment, the capacity state of the coolant in the heat dissipation box 10 is controlled according to the different states of the chassis ambient temperature of the single server. Under normal circumstances, the higher the chassis ambient temperature, the higher the capacity of the coolant. For example, the capacity of the coolant in the heat dissipation box 10 of the single server is 80%, and the central processing unit is running at 90% load. The overheating of the device causes the chassis ambient temperature to continue to rise. At this time, the capacity of the coolant in the heat dissipation box 10 needs to be increased from 80% to 100% to accelerate heat dissipation.

[0058] The embodiment of the present application provides a centralized cooling system for an immersion server cabinet. By setting multiple groups of single-server intelligent heat exchange systems and a whole-cabinet intelligent exchange system corresponding to multiple single servers on the server cabinet, the embodiment of the present application first immerses the server chassis with the coolant in the single-server intelligent heat exchange system to take away the heat of the single server. Then, when the single-server intelligent heat exchange system cannot meet the cooling requirements of the single server, the server chassis is immersed in the coolant in the whole-cabinet intelligent exchange system to take away the heat of the single server. This improves the safety of heat dissipation on the one hand and the heat dissipation efficiency on the other.

[0059] In addition, it should be noted that in this embodiment, reference Figure 1 , the server cabinet is also equipped with:

[0060] A main cold fluid supply line 401, connected to the liquid outlet of the whole-cabinet intelligent exchange system 30 and the heat dissipation pipeline of each single-server intelligent heat exchange system 20, is used to supply the coolant in the whole-cabinet intelligent exchange system 30 or the coolant in the single-server intelligent heat exchange system 20 adjacent to the bottom layer of the overheated single server to the heat dissipation box 10 of the overheated single server, wherein the overheated single server is a single server whose coolant in the single-server intelligent heat exchange system 20 is empty or whose heat dissipation box is filled with coolant, but whose chassis ambient temperature exceeds the target operating ambient temperature threshold;

[0061] The return fluid supply main line 402 is connected to the return liquid port of the whole cabinet intelligent exchange system 30 and the heat dissipation pipeline of each single server intelligent heat exchange system 20, and is used to recover the cooling liquid after heat dissipation exchange with the server chassis of the overheated single server to the whole cabinet intelligent exchange system 30.

[0062] Specifically, refer to Figure 2 , Figure 2 This is a schematic diagram of a coolant distribution and scheduling scenario in a heat sink of an overheated single server provided in this embodiment, wherein: Figure 2 The overheated single server is a single server in the heat sink 10 corresponding to the second group of single-server intelligent heat exchange systems 20. When the coolant in the intelligent heat exchange system 20 of the overheated single server is not empty or the heat sink 10 of the overheated single server is not filled with coolant, but the chassis ambient temperature exceeds the target operating ambient temperature threshold, the coolant in the heat sink 10 of the overheated single server flows out of the intelligent heat exchange system 20 of the overheated single server, flows into the heat sink 10, and then flows back to the intelligent heat exchange system 20 of the overheated single server (refer to Figure 2In the embodiment of the present invention, when the coolant in the single-server intelligent heat exchange system 20 of the overheated single server is empty or the heat sink 10 of the overheated single server is filled with coolant, but the chassis ambient temperature exceeds the target operating ambient temperature threshold, the coolant in the heat sink 10 of the overheated single server flows out from the whole cabinet intelligent exchange system 30 or the single-server intelligent heat exchange system 20 adjacent to the bottom layer of the overheated single server (i.e., the first group of single-server intelligent heat exchange systems 20), flows into the heat sink 10 of the overheated single server through the cold fluid supply main line 401, and then flows back to the whole cabinet intelligent exchange system 30 through the return fluid supply main line 402.

[0063] Figure 3 This is a structural diagram of a centralized cooling system for an immersion server cabinet provided by another embodiment of the present application. Figure 3 As shown, each of the heat dissipation pipelines is connected to the cold fluid supply main pipeline 401 via an inlet three-way switch 501, and each of the heat dissipation pipelines is also connected to the return fluid supply main pipeline 402 via an outlet three-way switch 502;

[0064] The inlet three-way switch 501 and the outlet three-way switch 502 are used to control the distribution and scheduling of the cooling liquid in the single-server intelligent heat exchange system 20 or the whole cabinet intelligent exchange system 30.

[0065] Specifically, refer to Figure 4 The inlet three-way switch 501 includes three switches a1, a2 and a3, and the outlet three-way switch 502 also includes three switches b1, b2 and b3. By controlling the status of these six switches, the distribution and scheduling of the cooling liquid in the single-server intelligent heat exchange system 20 or the whole cabinet intelligent exchange system 30 is controlled.

[0066] In some embodiments, when the coolant in the single-server intelligent heat exchange system 20 is not empty or the heat sink 10 of the single server is not filled with coolant, but the chassis ambient temperature exceeds the target working environment temperature threshold, a1 and b1 are in the closed state, and a2, a3, b2, and b3 are all in the open state, controlling the coolant in the single-server intelligent heat exchange system 20 to flow into the heat sink 10 of the single server.

[0067] In some embodiments, when the coolant in the single-server intelligent heat exchange system 20 is empty or the heat sink 10 of the single server is filled with coolant, but the chassis ambient temperature exceeds the target working environment temperature threshold, a2 and b2 are in the closed state, and a1, a3, b1, and b3 are all in the open state, controlling the coolant in the entire cabinet intelligent exchange system 30 to flow into the heat sink 10 of the single server.

[0068] In some embodiments, when the coolant in the single-server intelligent heat exchange system 20 is empty or the heat sink 10 of the single server is filled with coolant, but the chassis ambient temperature exceeds the target working environment temperature threshold, and the coolant in the single-server intelligent heat exchange system 20 adjacent to the bottom layer of the single-server intelligent heat exchange system 20 is not empty, and the chassis ambient temperature of the single server corresponding to the bottom layer of the single-server intelligent heat exchange system 20 does not exceed the target working environment temperature threshold, a1 and a2 of the bottom layer of the single-server intelligent heat exchange system 20 are in the open state, a3 of the bottom layer of the single-server intelligent heat exchange system 20 is in the closed state, and the states of b1, b2 and b3 remain unchanged, controlling the coolant in the bottom layer of the single-server intelligent heat exchange system 20 to flow into the heat sink 10 of the single server whose chassis ambient temperature exceeds the target working environment temperature threshold.

[0069] The centralized cooling system for an immersion server cabinet provided in the embodiment of the present application realizes flexible distribution and scheduling of cooling liquid by setting multiple groups of inlet three-way switches 501 and outlet three-way switches 502.

[0070] Figure 5 This is a structural diagram of a centralized cooling system for an immersion server cabinet provided by another embodiment of the present application. Figure 5 As shown, an inlet Tesla valve 601 is further provided between the inlet three-way switch 501 and the liquid inlet of the heat dissipation box 10, and an outlet Tesla valve 602 is further provided between the outlet three-way switch 502 and the liquid outlet of the heat dissipation box 10; the inlet Tesla valve 601 and the outlet Tesla valve 602 are used to control the one-way flow of coolant from the liquid inlet into the heat dissipation box 10, and then out of the liquid outlet after heat dissipation exchange with the server chassis of the single server.

[0071] It should be noted that the Tesla valve is a complex system of pipes, consisting of a series of alternating branching structures. Each pipe is divided into two branches, one of which is slightly inclined, while the other bends into a semi-circle and returns to the inclined pipe. The Tesla valve can increase or decrease the number of branches as needed. Due to the unique structure of the Tesla valve, the resistance to reverse flow is much greater than the resistance to forward flow. Coolant enters the pipe from the forward direction, and one-way flow of liquid and gas is achieved without any moving parts or electronic components. Utilizing spatial structure to propel liquid, the principles of fluid mechanics are cleverly utilized to achieve one-way flow, compensating for the shortcomings of movable parts (valves) that are easily damaged, complex in structure, and high in cost.

[0072] In addition, in this embodiment, a condenser 70 is further provided between the outlet Tesla valve 602 and the outlet three-way switch 502; the condenser 70 is used to cool the coolant that has changed into a gaseous state after heat dissipation exchange with the heating element of the server chassis back to a liquid coolant.

[0073] Specifically, the coolant starts from the inlet Tesla valve 601 and flows into the heat sink 10. The coolant immerses the server chassis in the heat sink 10 and takes away the heat of the single server in the server chassis. At the same time, the coolant undergoes a phase change reaction with the heating element at the bottom of the server chassis. The coolant absorbs heat and vaporizes. When the coolant changes from liquid to gas, it absorbs a large amount of heat and takes away excess heat from the heating element. In addition, the outlet Tesla valve 602 unidirectionally conducts liquid and gaseous coolant to prevent the gaseous coolant from flowing back into the heat sink 10 and affecting the heat dissipation effect. Then the gaseous coolant is processed by the condenser 70, cooled to liquid coolant, and flows back smoothly.

[0074] The centralized cooling system for an immersion server cabinet provided in the embodiment of the present application realizes one-way flow of the coolant by providing an inlet Tesla valve 601 and an outlet Tesla valve 602 and utilizing the unique structural characteristics of the Tesla valve. In addition, by adding a condenser 70, the coolant that has changed phase into a gaseous state is cooled back to a liquid state, thereby reducing the loss of the coolant.

[0075] Figure 6 FIG. 1 is a flow chart of a centralized heat dissipation method for an immersion server cabinet provided by an embodiment of the present application. Figure 6 As shown, the method is applied to any of the above-mentioned liquid-immersed server cabinet centralized cooling systems, including step 610 and step 620. The method flow steps are only a possible implementation of the present application.

[0076] Step 610: Detecting that the chassis ambient temperature of a single server exceeds a target ambient temperature threshold, extracting coolant from a single server intelligent heat exchange system corresponding to the single server into a heat dissipation box of the single server to perform heat dissipation control on the single server;

[0077] Step 620: If it is detected that the coolant in the intelligent heat exchange system of the single server is empty or the heat sink is filled with coolant, but the chassis ambient temperature of the single server exceeds the target working ambient temperature threshold, coolant is extracted from the entire cabinet intelligent exchange system to the heat sink of the single server to perform heat dissipation control on the single server.

[0078] In this embodiment, after the server cabinet starts running, each group of single-server intelligent heat exchange systems 20 enters its own independent heat dissipation determination logic state. Specifically, the chassis ambient temperature of the single server is continuously detected at preset intervals, and it is determined whether the chassis ambient temperature of the single server exceeds the target ambient temperature threshold C. If it does not exceed, the chassis ambient temperature of the single server is continuously detected at preset intervals. If it exceeds, the coolant in the single-server intelligent heat exchange system 20 is extracted to the heat dissipation box 10 of the single server to perform heat dissipation control on the single server. Thereafter, the chassis ambient temperature of the single server is continuously detected at preset intervals, and the status of the coolant in the single-server intelligent heat exchange system 20 and the coolant in the heat dissipation box 10 are simultaneously detected. If it is detected that the coolant in the single-server intelligent heat exchange system 20 is empty or the heat dissipation box 10 is filled with coolant, but the chassis ambient temperature of the single server exceeds the target working ambient temperature threshold C, coolant is extracted from the whole cabinet intelligent exchange system 30 to the heat dissipation box 10 of the single server.

[0079] In some embodiments, after detecting that the chassis ambient temperature of the single server exceeds the target ambient temperature threshold, the method further includes:

[0080] It is detected that the coolant in the single-server intelligent heat exchange system corresponding to the single server is empty, and coolant is extracted from the whole cabinet intelligent exchange system to the heat dissipation box of the single server to perform heat dissipation control on the single server.

[0081] In this embodiment, before the coolant in the single-server intelligent heat exchange system 20 is extracted into the heat dissipation box 10 of the single server to perform heat dissipation control on the single server, it is necessary to first detect whether the coolant in the single-server intelligent heat exchange system 20 is empty. If it is empty, the coolant is directly extracted from the whole cabinet intelligent exchange system 30 into the heat dissipation box 10 of the single server.

[0082] In some embodiments, before extracting cooling liquid from the whole cabinet intelligent switching system to the heat dissipation box of the single server to perform heat dissipation control on the single server, the method further includes:

[0083] Determining that a status of a target single server corresponding to the single server meets a preset condition;

[0084] The target single server includes a first target single server adjacent to the bottom layer of the single server and a second target single server located at an upper layer of the single server;

[0085] The preset condition is used to determine whether the condition for extracting coolant from the entire cabinet intelligent switching system to the heat dissipation box of the single server is met.

[0086] Specifically, in this embodiment, the preset condition includes at least one of the following:

[0087] When coolant is not extracted from the single-server intelligent heat exchange system corresponding to the first target single server to the heat dissipation box of the single server, the chassis ambient temperature of the first target single server exceeds the target ambient temperature threshold;

[0088] Cooling liquid has been extracted from the whole cabinet intelligent switching system to the heat dissipation box of the second target single server;

[0089] The coolant in the single-server intelligent heat exchange system corresponding to the first target single server is empty;

[0090] When coolant is extracted from the single-server intelligent heat exchange system corresponding to the first target single server into the heat dissipation box of the single server, the chassis ambient temperature of the first target single server exceeds the target ambient temperature threshold.

[0091] In addition, it should be noted that, in this embodiment, when the chassis ambient temperature of the first target single server does not exceed the target ambient temperature threshold, coolant is not extracted from the whole cabinet intelligent exchange system 30 to the heat dissipation box of the second target single server, and the coolant in the single-server intelligent heat exchange system 20 corresponding to the first target single server is not empty, coolant is extracted from the single-server intelligent heat exchange system 20 corresponding to the first target single server to the heat dissipation box 10 of the single server.

[0092] For ease of understanding, this is explained. In one application scenario, the coolant in the single-server intelligent heat exchange system C of the single-server C cannot meet the heat dissipation needs of the single-server C (that is, the coolant in the single-server intelligent heat exchange system C is empty or the heat sink C of the single-server C is filled with coolant, but the chassis ambient temperature of the single-server C exceeds the target working environment temperature threshold). The bottom layer of the single-server C also has a single server A and a single server B, wherein the single server B is located between the single server C and the single server A, that is, the single server B is the first target single server adjacent to the bottom layer of the single server C, and the upper layer of the single server C also has a second target single server (single server D, single server E and single server F).

[0093] Before extracting coolant from the whole cabinet intelligent switching system to the heat sink C of the single server C, first detect whether the chassis ambient temperature of the single server B (i.e., the first target single server) exceeds the target ambient temperature threshold. If it exceeds, directly extract coolant from the whole cabinet intelligent switching system to the heat sink C of the single server C.

[0094] If it does not exceed, continue to determine whether coolant is currently being extracted from the entire cabinet intelligent switching system to the heat dissipation boxes of single server D, single server E, and single server F (i.e., the second target single server). If so, directly extract coolant from the entire cabinet intelligent switching system to the heat dissipation box C of single server C.

[0095] If not, continue to determine whether the coolant in the single server intelligent heat exchange system B of single server B (i.e., the first target single server) is empty. If it is empty, directly extract the coolant from the entire cabinet intelligent exchange system to the heat dissipation box C of single server C.

[0096] If it is not empty, coolant is extracted from the single-server intelligent heat exchange system B to the heat sink C of the single server C. Then, the chassis ambient temperature of the single server B is continuously detected at preset intervals. If the chassis ambient temperature of the single server B exceeds the target ambient temperature threshold, the extraction of coolant from the single-server intelligent heat exchange system B is stopped, and coolant is extracted from the entire cabinet intelligent exchange system to the heat sink C of the single server C.

[0097] The embodiment of the present application provides a centralized heat dissipation method for an immersion server cabinet. The method first immerses the server chassis with the coolant in the single-server intelligent heat exchange system to remove the heat of the single server. Then, when the single-server intelligent heat exchange system cannot meet the heat dissipation requirements of the single server, the coolant in the entire cabinet intelligent exchange system is used to immerse the server chassis to remove the heat of the single server. This improves the safety of heat dissipation on the one hand, and the heat dissipation efficiency on the other.

[0098] It should be noted that each implementation method of the present application can be freely combined, the order can be changed, or it can be executed separately, and does not need to rely on or depend on a fixed execution order.
