At the same time, more and more data are generated behind it, and the data is growing rapidly at a speed beyond imagination. The exponentially growing data requires more and more computing power to analyze and process, which in turn generates more power consumption. For example, with the continuous increase in computing power demand, the average power consumption of the graphics processing unit (Graphics Processing Unit, referred to as GPU) has jumped from 300W to more than 1000W, which has brought huge challenges to the heat dissipation operation of the server.

[0003] At present, servers often rely on the cooling devices (such as air conditioners) in the computer room where they are located to perform heat dissipation operations. However, when the power consumption on the server is relatively high, the cooling devices in the computer room cannot quickly take away the relatively concentrated heat. This not only fails to meet the demand for increased heat flux density, but also reduces the stability and reliability of server use. Utility Model Content

[0052] Definition of terms:

[0053] Cooling Distribution Unit (CDU): A system used to distribute cooling liquid between liquid-cooled electronic equipment, providing secondary side flow distribution, pressure control, physical isolation, anti-condensation and other functions.

[0054] Water collection manifold: It is the middleware between the CDU and the server, used to provide liquid to the server for heat transfer operations.

[0055] In the following, some embodiments of the present invention are described in detail in conjunction with the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and features in the embodiments can be combined with each other.

[0056] In order to facilitate understanding of the specific structural features and implementation principles of the liquid cooling device, the control method, the device and the device of the liquid cooling device in this embodiment, the relevant technologies are briefly described below:

[0057] With the rapid development of big data and cloud computing, big data and cloud computing have made the world more interconnected and human life more convenient. At the same time, more and more data are generated behind it, and the data is growing at a rate beyond imagination. Through rough statistics and predictions of the data, it can be seen that the global data circle will increase from 33ZB (zettabytes) in 2018 to 175ZB in 2025. The exponentially growing data requires more and more computing power for analysis and processing. Looking back at the development of processors in the past 40 years, it can be seen that Moore's Law is gradually slowing down. When Moore's Law slows down, there are mainly two directions to pursue higher computing power:

[0058] (1) Inward, more computing units are built inside the server to improve the computing power of a single machine. This directly leads to new challenges in chip power consumption and heat dissipation. For example, the power consumption of early graphics processors (GPUs) was about 200W, while the power consumption of the latest generation of GPUs has reached 1200W. At this rate of development, air cooling technology can no longer be used to solve the heat dissipation problem of chips.

[0059] (2) In the outward direction, cloud computing centralizes computing resources. The increase in high density will inevitably lead to an increase in heat density, which will bring huge energy consumption challenges to data centers that support the stable operation of servers. According to statistics, in 2018, the electricity consumption of data centers across China was more than 160 billion kWh, which is more than the 150 billion kWh of electricity consumption in Shanghai in 2018, and is equivalent to the annual power generation of the Three Gorges Dam. Therefore, low-energy data centers are not only related to environmental sustainable development, but also directly determine the computing cost and service competitiveness.

[0060] In general, when the power consumption on the server is relatively high, the existing heat dissipation method cannot quickly remove the relatively concentrated heat. This not only fails to meet the demand for increased heat flux density, but also reduces the stability and reliability of server use.

[0061] In order to solve the above technical problems, this embodiment provides a liquid cooling device, a control method, a device and a device for the liquid cooling device. The liquid cooling device can meet the heat dissipation requirements of high heat flux density and ensure the stable reliability of the server 1. For details, refer to the attached Figure 1 As shown, this embodiment provides a liquid cooling device, which can be implemented as a cabinet structure. Specifically, the liquid cooling device may include: a server 1 and at least two cooling distribution units 2. The server 1 and the at least two cooling distribution units 2 may respectively include components:

[0062] The server 1 comprises: a heat generating element 101 and a heat conducting element 102 for dissipating heat from the heat generating element 101, wherein the heat conducting element 102 is connected to a water collecting and branching pipe 3, so as to obtain liquid for heat transfer through the water collecting and branching pipe 3;

[0063] At least two cold distribution units 2, each of which includes: a heat exchanger 201, and a hydraulic power component 202 connected to the heat exchanger 201. The heat exchanger 201 and the hydraulic power component 202 are connected to the heat conductor 102 through a water collecting and branching pipe 3, and are used to obtain the liquid transmitted by the heat conductor 102 through the water collecting and branching pipe 3 and perform heat exchange operations on the liquid.

[0064] Among them, server 1 can be a device for realizing preset functions, and different preset functions can correspond to different servers. For example, when the preset function is AI computing function, server 1 can be an AI server; when the preset function is communication function, server 1 can be a communication server; when the preset function is database service function, server 1 can be a database server. Technical personnel in this field can flexibly configure and adjust server 1 according to specific application requirements.

[0065] In addition, the number of servers 1 may be one or more. When the number of servers 1 is multiple, the multiple servers 1 may correspond to the same structural structure or different structural structures. Specifically, each server 1 may include: a heating element 101 and a heat conducting element 102 for transmitting the heat generated by the heating element 101. For the heating element 101, the number of the heating element 101 may be one or more, and different heating elements 101 may correspond to different functions. In some instances, the heating element 101 may include at least one of the following: a main chip, a storage element, a power supply, a GPU, a core processor (Central Processing Unit, referred to as CPU), a memory, a network card, and other components that can generate heat.

[0066] When the heating element 101 is used for data processing operations, the heating element 101 will generate a certain amount of heat. In order to ensure the stable and reliable operation of the heating element 101, the server 1 includes a heat conductive element 102 for dissipating the heat of the heating element 101. In some instances, one heat conductive element 102 may correspond to one or more heating elements 101. Specifically, the heat conductive element 102 may be a plate-like structure, and the heat conductive element 102 is arranged at the upper end of the heating element 101 and contacts the upper surface of the heating element 101. Specifically, the heat conductive element 102 may contact the upper surface of the heating element 101 through a heat conductive material, so that the heat generated by the heating element 101 can be transmitted.

[0067] In order to accurately and stably transfer the heat generated by the heating element 101, a water collecting and branching pipe 3 is connected to the heat conductor 102. In some instances, the heat conductor 102 can be connected to the water collecting and branching pipe 3 via a quick connector 4 and a hose 5; or, the heat conductor 102 can be directly connected to the water collecting and branching pipe 3 via the quick connector 4, which facilitates the replacement and maintenance of the heat conductor 102. The heat conductor 102 can obtain liquid for heat transfer through the connected water collecting and branching pipe 3. The liquid can be any one of the following: water, fluorinated liquid, silicone oil heat dissipation liquid, grease heat dissipation liquid, etc. Those skilled in the art can flexibly configure and adjust the liquid in the water collecting and branching pipe 3 according to specific application scenarios and application requirements.

[0068] In addition, for the at least two cold distribution units 2 included in the liquid cooling device, in order to ensure the quality and effect of the heat dissipation operation on the heat generating component 101, the number of cold distribution units 2 included in the liquid cooling device in this embodiment can be two or more, and at least two cold distribution units 2 can perform heat dissipation operations on the server 1 in a synchronous manner or an asynchronous manner, as long as the quality and effect of the heat dissipation of the server 1 can be guaranteed.

[0069] Specifically, for the cold distribution unit 2, each cold distribution unit 2 may include: a heat exchanger 201, and a hydraulic power component 202 connected to the heat exchanger 201, wherein the hydraulic power component 202 can be implemented as a hydraulic pump, and the number of hydraulic power components 202 connected to the heat exchanger 201 is one, which can simplify the structure of a single cold distribution unit 2 and facilitate the management and maintenance operations of the cold distribution unit 2.

[0070] For the heat exchanger 201 and the hydraulic power component 202, they can be connected to the water collecting branch pipe 3. Specifically, the heat exchanger 201 and the hydraulic power component 202 are connected to the water collecting branch pipe 3 through the quick connector 4 and the hose 5; or, the heat exchanger 201 and the hydraulic power component 202 can be directly connected to the water collecting branch pipe 3 through the quick connector 4, so that the heat exchanger 201 and the hydraulic power component 202 can obtain the liquid transmitted by the heat conductor 102 through the water collecting branch pipe 3, and then the liquid can be subjected to heat exchange operations, which can meet the heat dissipation requirements of high heat flux density and ensure the stable reliability of the use of the server 1.

[0071] Specifically, the implementation principle of the liquid cooling device in this embodiment is as follows: the heat conductor 102 obtains the liquid for heat transfer through the water collecting and branching pipe 3. When the heating element 101 is working and generates heat, the liquid in the heat conductor 102 can absorb the heat generated by the heating element 101, and then transfer the heat-absorbing liquid to the cold distribution unit 2 through the water collecting and branching pipe 3. The cold distribution unit 2 can perform heat exchange operation on the heat-absorbing liquid through the heat exchanger 201 and the hydraulic power component 202, and can return the exchanged liquid to the water collecting and branching pipe 3, thereby realizing a heat exchange circuit, so that the heat dissipation operation of the heating element 101 in the server 1 can be quickly realized.

[0072] In addition, the cold capacity distribution unit 2 in this embodiment can not only realize the heat dissipation operation of the server 1, but also provide the following functions: secondary flow measurement distribution function, pressure control function, physical isolation function, anti-condensation function, etc. Specifically, the cold capacity distribution unit 2 may include a proportional valve and a pressure gauge connected to the heat exchanger 201, and a one-way valve connected to the hydraulic power part 202. Then, the proportional valve, the pressure gauge and the one-way valve can be used to perform secondary flow distribution operations on the liquid in the water collection and branch pipe 3 and the liquid that can be provided by the computer room pipe to improve and ensure the heat dissipation quality and effect of the server 1; and the pressure gauge can be used to pressurize the liquid in each pipe to achieve normal flow of the liquid in the pipe to achieve heat exchange operation.

[0073] In this embodiment, the working operations of multiple cooling distribution units 2 in the liquid cooling device are independent of each other, and any two cooling distribution units 2 are physically isolated from each other. In this way, when any cooling distribution unit 2 fails, it will not affect the cooling operation of the server by other cooling distribution units 2, thereby improving and ensuring the continuity and stability of the cooling operation of the server.

[0074] On the other hand, the cold capacity distribution unit 2 in this embodiment can be used for sensing environmental information through a sensing device, such as a thermometer and a hygrometer. The temperature information sensed by the thermometer and the humidity information sensed by the hygrometer can be used to determine whether the current environment is suitable for the normal operation of the liquid cooling equipment. After analyzing and processing the temperature information and the humidity information, when it is determined that the current environment is not suitable for the normal operation of the liquid cooling equipment, for example, there is a risk of condensed water. The cold capacity distribution unit 2 can give an alarm indication, specifically, it can use a sound alarm or an alarm indicator light to remind the user that the current environment is not suitable for the normal operation of the liquid cooling equipment. After analyzing and processing the temperature information and the humidity information, when it is determined that the current environment is suitable for the normal operation of the liquid cooling equipment, the cold capacity distribution unit 2 can perform normal processing operations, thereby effectively realizing anti-condensation operations.

[0075] The liquid cooling device provided in this embodiment can stably and promptly perform heat dissipation operations on the heat generated by the server 1 through the at least two cold distribution units 2 configured. Specifically, heat exchange operations are performed through the heat exchanger and hydraulic power parts included in the cold distribution unit. This not only meets the heat dissipation requirements of high heat flux density, but also ensures the stable reliability of the use of the server 1. In addition, when a cold distribution unit 2 in the liquid cooling device fails, the heat generated by the server 1 can be promptly and effectively dissipated through other cold distribution units 2, thereby effectively realizing the non-stop operation of the liquid cooling device when a component fails. This not only meets the reliability requirements of the liquid cooling device, but also improves the practicality of the liquid cooling device.

[0076] Based on the above embodiments, Figure 2 Schematic diagram of the liquid flow path in the heat conducting member provided in the embodiment of the utility model Figure 1 ; Reference Attachment Figure 1-Figure 2 As shown, in order to improve the quality and effect of the heat dissipation operation on the server 1, a liquid flow channel 1021 can be provided on the heat conductive part 102 in the hydraulic equipment. In some instances, the liquid flow channel 1021 can be provided on the surface of the heat conductive part 102, so that the liquid in the liquid flow channel 1021 can effectively contact the heat generating part 101, so as to realize a fast and effective transmission operation of the heat generated by the heat generating part 101.

[0077] In other instances, the liquid flow channel 1021 may be composed of a plurality of fins embedded in the heat conductive element 102. In this case, the liquid flow channel 1021 is embedded in the interior of the heat conductive element 102. This not only ensures that the liquid flow channel 1021 can quickly and effectively transfer the heat generated by the heating element 101, but also improves the convenience of installing and arranging the heat conductive element 102 and the heating element 101.

[0078] For the liquid flow channel 1021 in the heat conducting member 102, in order to improve the flexibility and reliability of the use of the liquid cooling device, the distribution of the liquid flow channel 1021 in the heat conducting member 102 is adapted to the heat flow distribution in the heating member 101. Figure 2 As shown, when the heat flow distribution of the heating element 101 is used to identify the right area of ​​the heating element 101 as the main heating area, in order to ensure the quality and effect of heat dissipation of the heating element 101, the liquid flow channel 1021 in the heat conductive element 102 can be mainly distributed in the right area of ​​the heat conductive element 102, so that the distribution of the liquid flow channel 1021 in the heat conductive element 102 is compatible with the heat flow distribution in the heating element 101.

[0079] Similarly, see Appendix Figure 3 As shown, when the heat flow distribution of the heating element 101 is used to identify the left area of ​​the heating element 101 as the main heating area, in order to ensure the quality and effect of heat dissipation of the heating element 101, the liquid flow channel 1021 in the heat conductive element 102 can be mainly distributed in the left area of ​​the heat conductive element 102, so that the distribution of the liquid flow channel 1021 in the heat conductive element 102 is compatible with the heat flow distribution in the heating element 101.

[0080] It should be noted that when the heat generating element 101 includes the first heat generating element 101a and the second heat generating element 101b, the first heat generating element 101a is adapted to the first heat conducting element 102, and the heat flow distribution of the first heat generating element 101a can cover the heat flow distribution of the second heat generating element 101a, the first heat conducting element 102 is adapted to the second heat generating element 101b.

[0081] For example, see Attachment Figure 4 As shown, when the heating element 101 includes the first heating element 101a and the second heating element 101b, the heat flow distribution of the first heating element 101a can cover the heat flow distribution of the second heating element 101b, that is, the heat flow distribution area of ​​the first heating element 101a covers the heat flow distribution area of ​​the second heating element 101b. If the heat-conducting element 102 is adapted to the first heating element 101a, the first heat-conducting element 102 is adapted to the second heating element 101b, that is, when the liquid flow channel 1021 in the heat-conducting element 102 can accurately dissipate heat for the heating elements 101 with a variety of heat flow distributions, it means that the heat-conducting element 102 can be adapted to multiple heating elements 101, and the heat flow distributions of the multiple heating elements 101 can be the same or different.

[0082] In addition, for the water collecting and branching pipe 3, in order to be able to perform stable heat dissipation operations on the heating element 101 through the water collecting and branching pipe 3 and the heat conducting element 102, the water collecting and branching pipe 3 may include a first pipe 301 and a second pipe 302; one end of the first pipe 301 is connected to the liquid flow channel 1021, for inputting a first type of liquid for heat transfer into the liquid flow channel 1021, and the other end is respectively connected to at least two cold distribution units 2, for obtaining the first type of liquid for heat dissipation operations through the cold distribution unit 2; one end of the second pipe 302 is connected to the liquid flow channel 1021, for receiving the second type of liquid output by the liquid flow channel 1021, and the other end is respectively connected to at least two cold distribution units 2, for transmitting the second type of liquid output by the liquid flow channel 1021 to the cold distribution unit 2 for heat exchange operations.

[0083] At this time, the heat dissipation principle of the liquid cooling device can be: one end of the first pipe 301 can be connected to the liquid flow channel 1021 in the heat conducting element 102 through the quick connector 4, and the first pipe 301 includes a first type of liquid for heat transfer. The temperature of the first type of liquid is relatively low. When it is specifically implemented, the first type of liquid can be implemented as cold water; in order to achieve heat dissipation operation, the first pipe 301 can input the first type of liquid into the liquid flow channel 1021, and the first type of liquid in the liquid flow channel 1021 can absorb the heat generated by the heating element 101 and become a second type of liquid. The temperature of the second type of liquid is higher than the temperature of the first type of liquid. When it is specifically implemented , the second type of liquid can be realized as hot water; then the second type of liquid can be transferred to the second pipe 302 through the quick connector 4 and the hose 5, and the second pipe 302 can transfer the obtained second type of liquid to at least two cold distribution units 2 through the quick connector 4 and the hose 5. After the at least two cold distribution units 2 obtain the second type of liquid in the second pipe 302, the second type of liquid can be heat exchanged to obtain the first type of liquid after heat exchange, and then the first type of liquid can be transferred to the first pipe 301 through the quick connector 4, thereby effectively realizing a liquid reflux heat dissipation operation, thereby ensuring the heat dissipation quality and effect of the liquid cooling equipment.

[0084] In some other examples, in order to accurately implement the heat dissipation operation, at least two cooling distribution units 2 need to be connected to the liquid loop pipeline 7 provided by the machine room. In this case, there are the following two implementation methods:

[0085] Implementation method 1: at least two cooling distribution units 2 are connected to the same liquid loop pipeline 7, wherein the liquid loop pipeline 7 is deployed in the machine room;

[0086] Implementation method 2: at least two cooling capacity distribution units 2 are connected to different liquid loop pipelines 7, wherein the different liquid loop pipelines 7 are deployed in the same machine room.

[0087] For the above-mentioned implementation method 1, when the liquid loop pipeline 7 fails, the liquid cooling device may be unable to dissipate heat for the server 1 due to lack of cooling capacity, and the liquid cooling device needs to be shut down for maintenance. This not only increases the difficulty of maintenance of the liquid cooling device, but also reduces the heat dissipation quality and effect of the liquid cooling device.

[0088] In order to avoid the occurrence of the above situation, the cold energy distribution unit 2 in this embodiment can be preferably deployed in the computer room in the second implementation mode, that is, at least two cold energy distribution units 2 in the liquid cooling equipment can be respectively connected to different liquid loop pipes 7 in the computer room to perform heat exchange operations on the liquid that absorbs heat in the heat exchanger 201 through the liquid loop pipe 7.

[0089] Specifically, a plurality of liquid loop pipes 7 may be configured in the machine room, and different liquid loop pipes 7 may be referred to as redundant pipes. Different liquid loop pipes 7 may be connected to different cooling distribution units 2. When the liquid loop pipe 7 is connected to the cooling distribution unit 2, the liquid loop pipe 7 may perform heat exchange operations on the liquid that absorbs heat in the heat exchanger 201, thereby effectively enabling the heat exchanger 201 and the hydraulic power component 202 to dissipate the heat of the heating component 101 into the air, thereby ensuring the heat dissipation quality and effect of the liquid cooling equipment.

[0090] In addition, different liquid loop pipes 7 are independent of each other. For example, the machine room may be provided with liquid loop pipe 7a (not shown), liquid loop pipe 7b, and liquid loop pipe 7c. The above-mentioned liquid loop pipe 7a may be connected to the cold distribution unit 2a, the liquid loop pipe 7b may be connected to the cold distribution unit 2b, and the liquid loop pipe 7c may be connected to the cold distribution unit 2c. The above-mentioned liquid loop pipe 7a and the cold distribution unit 2a, the liquid loop pipe 7b and the cold distribution unit 2b, and the liquid loop pipe 7c and the cold distribution unit 2c are independent of each other. In this way, when any one of the liquid loop pipes 7 fails, it will not affect other liquid loop pipes 7, thereby ensuring the heat dissipation quality and effect of the liquid cooling equipment.

[0091] In addition, in order to be able to stably perform heat dissipation operations on the heat generating element 101 based on the liquid cooling device, the liquid loop pipeline 7 may include: an inlet pipeline 701 and an outlet pipeline 702. One end of the heat exchanger 201 is connected to the inlet pipeline 701 through a proportional valve to obtain a first type of liquid for heat exchange through the inlet pipeline 701. The proportional valve is used to adjust the liquid flow rate of the inlet pipeline 701; the other end is connected to the outlet pipeline 702 to discharge the second type of liquid that absorbs heat from the outlet pipeline 702.

[0092] Specifically, when the liquid loop pipeline 7 includes a liquid inlet pipeline 701 and a liquid outlet pipeline 702, the heat dissipation principle of the liquid cooling equipment can be: the heat exchanger 201 in the liquid cooling equipment can obtain the first type of liquid for heat exchange through the liquid inlet pipeline 701, that is, the computer room can input the first type of liquid into the heat exchanger 201 through the liquid inlet pipeline 701. After the heat exchanger 201 obtains the first type of liquid, the heat generated by the heat exchange operation of the heat exchanger 201 can be absorbed by the first type of liquid to obtain the second type of liquid. The temperature of the second type of liquid is higher than that of the first type of liquid. After the second type of liquid is obtained, the second type of liquid can be discharged into the air through the liquid outlet pipeline 702, thereby effectively realizing the heat dissipation operation and further improving the heat dissipation quality and effect of the liquid cooling equipment.

[0093] In this embodiment, at least two cooling distribution units 2 are respectively connected to different liquid loop pipes 7 in the machine room, so that the liquid that absorbs heat in the heat exchanger 201 is heat exchanged through the liquid loop pipe 7, thereby ensuring the heat dissipation quality and effect of the liquid cooling equipment and further improving the practicability of the liquid cooling equipment.

[0094] Figure 5 A schematic diagram of the structure of the cooling capacity distribution unit 2 provided in the embodiment of the utility model; based on the above embodiment, refer to the attached Figure 5 As shown, when the liquid cooling device is working, in order to improve the flexibility and reliability of the use of the liquid cooling device, the cooling distribution unit 2 in different working states may correspond to different control strategies. At this time, each cooling distribution unit 2 in the liquid cooling device may also include:

[0095] A sensing unit 203, connected to at least one of the heat exchanger 201 and the hydraulic power component 202, for sensing an operating state of at least one of the heat exchanger 201 and the hydraulic power component 202;

[0096] Liquid cooling equipment also includes:

[0097] The control unit 6 is connected to at least two cooling capacity distribution units 2, and is used to determine the operating status of the cooling capacity distribution unit 2 through the sensing unit 203, and control the cooling capacity distribution unit 2 based on the operating status.

[0098] Specifically, since the cold distribution unit 2 can correspond to different operating states, for example: when the heat exchanger 201 or the hydraulic power component 202 in the cold distribution unit 2 fails, the cold distribution unit 2 is in a faulty state; when the heat exchanger 201 and the hydraulic power component 202 in the cold distribution unit 2 operate normally, the cold distribution unit 2 is in a normal state.

[0099] Since different operating states of the cooling distribution unit 2 can directly affect the heat dissipation quality and effect of the liquid cooling device, in order to accurately determine the operating state of the cooling distribution unit 2, each cooling distribution unit 2 may include a sensing unit 203 connected to at least one of the heat exchanger 201 and the hydraulic power component 202. Specifically, the sensing unit 203 may include a first sensing unit 203 connected to the heat exchanger 201 and a second sensing unit 203 connected to the hydraulic power component 202. In some examples, the first sensing unit 203 may include at least one of the following: a thermometer for sensing temperature or temperature difference; , a flow meter for sensing flow rate and flow velocity, a pressure gauge for sensing pipeline pressure, etc. The second sensing unit 203 may include at least one of the following: a flow meter for sensing flow rate and flow velocity, a leak detector for detecting whether there is a water leakage, a tachometer for detecting the rotation speed of the hydraulic power part 202, a pressure gauge for sensing pipeline pressure, etc. Those skilled in the art can flexibly configure and adjust the specific implementation method and type of the sensing unit 203 according to the working principle of the cold distribution unit 2, as long as it can be ensured that the working state of the cold distribution unit 2 can be accurately determined by the sensing unit 203, and it will not be repeated here.

[0100] The control unit 6 in the liquid cooling device can be connected to the sensing unit 203, and can actively or passively determine the operating status of the cold distribution unit 2 through the sensing unit 203. Specifically, when the sensing unit 203 detects that at least one of the heat exchanger 201 and the hydraulic power component 202 is faulty, it is determined that the cold distribution unit 2 is operating abnormally; when the sensing unit 203 detects that neither the heat exchanger 201 nor the hydraulic power component 202 is faulty, it is determined that the cold distribution unit 2 is operating normally.

[0101] Since different operating states of the cold capacity distribution unit 2 may correspond to different control strategies, after the control unit 6 obtains the operating state of the cold capacity distribution unit 2, the cold capacity distribution unit 2 may be controlled based on the operating state. In some instances, when the control unit 6 controls the cold capacity distribution unit 2 based on the operating state, the control unit 6 is used to execute: obtaining a mapping relationship between a pre-configured operating state and a control strategy; determining a control strategy corresponding to the operating state based on the mapping relationship; and controlling the cold capacity distribution unit 2 based on the control strategy, for example: the cold capacity distribution unit 2 may be controlled to stop operating based on a stop operating strategy; or, the cold capacity distribution unit 2 may be controlled to operate based on an operable strategy, thereby effectively realizing flexible control operations on the cold capacity distribution unit 2.

[0102] In other instances, the control unit 6 can control at least two cooling capacity distribution units 2 in combination with the data calculation amount corresponding to the server 1. Specifically, when the at least two cooling capacity distribution units 2 include a first cooling capacity distribution unit and a second cooling capacity distribution unit; the control unit 6 is used to: when the operating state of the first cooling capacity distribution unit is an abnormal state, obtain the data calculation amount corresponding to the server 1; control the second cooling capacity distribution unit 2 based on the data calculation amount to ensure the heat dissipation effect of the server 1.

[0103] Among them, at least two cold energy distribution units 2 may include a first cold energy distribution unit and a second cold energy distribution unit. The number of the first cold energy distribution unit and the second cold energy distribution unit may be one or more respectively. After performing status detection operation on at least two cold energy distribution units 2, the operating status of each cold energy distribution unit 2 can be obtained. When it is determined that the operating status of all cold energy distribution units 2 is normal, the operating status of the cold energy distribution unit 2 can be kept unchanged.

[0104] When the operating state of the first cooling capacity distribution unit is abnormal, in order to ensure the heat dissipation quality and effect of the liquid cooling equipment, the data calculation amount corresponding to the server 1 can be obtained. In some instances, the data calculation amount corresponding to the server 1 can be obtained by sensing the server 1 with a preset algorithm or a preset sensing device. Since the data calculation amount is closely related to the amount of heat that the server 1 can generate, for example: the larger the data calculation amount, the more heat the server 1 can generate; the smaller the data calculation amount, the smaller the heat that the server 1 can generate. Therefore, in order to ensure stable and effective heat dissipation operation of the server 1, the data calculation amount corresponding to the server 1 can be obtained.

[0105] After obtaining the data calculation amount, the second cooling capacity distribution unit 2 can be controlled based on the data calculation amount. In some instances, different data calculation amounts may correspond to different control strategies. After obtaining the data calculation amount, a target control strategy matching the data calculation amount can be determined, and then the second cooling capacity distribution unit 2 can be controlled based on the target control strategy. For example, when the data calculation amount is greater than or equal to a preset threshold, the control strategy is determined to be a first control strategy for increasing the flow ratio of the second cooling capacity distribution unit 2; when the data calculation amount is less than the preset threshold, the control strategy is determined to be a second control strategy for decreasing the flow ratio of the second cooling capacity distribution unit 2, which effectively ensures the heat dissipation quality and effect of the second cooling capacity distribution unit 2 while also ensuring the effective utilization rate of the liquid flow used for heat dissipation operations, thereby achieving flexible control of the second cooling capacity distribution unit 2.

[0106] In other instances, the second cooling capacity distribution unit 2 can be controlled not only based on the data calculation amount corresponding to the server 1, but also in combination with the quantity information of the second cooling capacity distribution unit 2. At this time, when the control unit 6 controls the second cooling capacity distribution unit 2 based on the data calculation amount, the control unit 6 is used to: determine the quantity information of the second cooling capacity distribution unit 2; and control the second cooling capacity distribution unit 2 based on the data calculation amount and the quantity information.

[0107] Among them, for the liquid cooling equipment, after the result of the liquid cooling equipment is determined, the number of cold distribution units 2 included in the liquid cooling equipment can be determined. Since the cold distribution unit 2 can correspond to different operating states when the liquid cooling equipment is used for heat dissipation operations, the cold distribution unit 2 with an abnormal operating state can be called the first cold distribution unit 2; the cold distribution unit 2 with a normal operating state can be called the second cold distribution unit 2. By performing timed or real-time sensing operations on the operating state of the cold distribution unit 2 through a sensing device, the quantity information of the second cold distribution unit 2 can be counted and determined.

[0108] Since the sum of the heat dissipation capacity of different numbers of second cooling capacity distribution units 2 is different, in order to ensure the heat dissipation quality and effect, after determining the quantity information of the second cooling capacity distribution units 2, the second cooling capacity distribution units 2 can be controlled based on the data calculation amount and the quantity information. In some examples, a control strategy corresponding to the data calculation amount and the quantity information is pre-configured, and after obtaining the data calculation amount and the quantity information, the control strategy corresponding to the data calculation amount and the quantity information can be determined, and the second cooling capacity distribution unit 2 is controlled based on the determined control strategy.

[0109] In other instances, when the control unit 6 controls the second cooling capacity distribution unit 2 based on the data calculation amount and quantity information, the control unit 6 is used to: determine the liquid flow ratio corresponding to each second cooling capacity distribution unit 2 based on the data calculation amount and quantity information; and control each second cooling capacity distribution unit 2 to perform heat dissipation operation based on the liquid flow ratio.

[0110] Specifically, since the data calculation amount can reflect the heat dissipation demand corresponding to the server 1, the quantity information of the second cooling capacity distribution unit 2 can reflect the heat dissipation capacity of the second cooling capacity distribution unit 2 to a certain extent. Since the second cooling capacity distribution unit 2 is based on liquid heat transfer to achieve heat dissipation operations, therefore, in order to be able to achieve accurate heat dissipation operations, after obtaining the data calculation amount and quantity information, the data calculation amount and quantity information can be analyzed and processed to determine the liquid flow ratio corresponding to each second cooling capacity distribution unit 2, wherein different second cooling capacity distribution units 2 can correspond to the same or different liquid flow ratios.

[0111] After obtaining the liquid flow ratio corresponding to each second cooling distribution unit 2, each second cooling distribution unit 2 can be controlled to perform heat dissipation operation based on the liquid flow ratio. This not only ensures the heat dissipation quality and effect of the cooling distribution unit 2, but also ensures the effective utilization rate of the liquid.

[0112] It should be noted that in order to avoid invalid amount of transmitted liquid used to achieve heat dissipation operation, the control unit 6 in this embodiment is used to: obtain the heat dissipation capacity of the second cold distribution unit 2 before controlling the second cold distribution unit 2 based on the data calculation amount; when the heat dissipation capacity meets the heat dissipation demand corresponding to the data calculation amount, control the operating state of the second cold distribution unit 2 to remain unchanged; when the heat dissipation capacity does not meet the heat dissipation demand corresponding to the data calculation amount, allow the second cold distribution unit 2 to be controlled based on the data calculation amount.

[0113] Specifically, before controlling the second cooling capacity distribution unit 2 based on the data calculation amount, the control unit 6 needs to first identify whether the second cooling capacity distribution unit 2 can perform a stable and effective cooling operation on the server 1. At this time, the cooling capacity of the second cooling capacity distribution unit 2 can be obtained first. In some instances, since the cooling capacity of the second cooling capacity distribution unit 2 is related to the number of second cooling capacity distribution units 2 and the liquid flow rate, the cooling capacity of the second cooling capacity distribution unit 2 can be determined by the number of second cooling capacity distribution units 2 and the liquid flow rate. Specifically, when the number of second cooling capacity distribution units 2 is greater, the cooling capacity of the second cooling capacity distribution unit 2 is higher, and vice versa, the cooling capacity is lower; similarly, when the liquid flow rate of the second cooling capacity distribution unit 2 is greater, the cooling capacity of the second cooling capacity distribution unit 2 is higher, and vice versa, the cooling capacity is lower.

[0114] After obtaining the heat dissipation capacity of the second cooling distribution unit 2, the heat dissipation capacity and the heat dissipation demand corresponding to the data calculation amount can be analyzed and processed to identify whether the heat dissipation capacity of the second cooling distribution unit 2 meets the heat dissipation demand corresponding to the data calculation amount. When the heat dissipation capacity meets the heat dissipation demand corresponding to the data calculation amount, it means that the second cooling distribution unit 2 at this time can stably and effectively perform heat dissipation operations on the server 1 and ensure the stable reliability of the operation of the server 1, thereby maintaining the operating state of the second cooling distribution unit 2 unchanged.

[0115] When the heat dissipation capacity does not meet the heat dissipation requirements corresponding to the data 2, it means that the second cooling distribution unit 2 cannot stably and effectively perform cooling operations on the server 1, that is, the stable operation of the server 1 cannot be guaranteed. At this time, in order to ensure the heat dissipation quality and effect of the server 1, the second cooling distribution unit 2 is allowed to be controlled based on the data calculation amount.

[0116] In general, the liquid cooling device provided in this embodiment installs a heat-conducting member 102 (for example, a cold plate) on the heating element 101 of the server 1, and uses the heat-conducting member 102 to absorb the heat generated by the heating element 101, and transfers the heat to the remote cold distribution unit 2 through the liquid flow channel 1021. At the same time, the cold distribution unit 2 transfers the heat to the cooling water in the computer room through the internal heat exchanger 201. The cold plate, as a heat transfer medium, can more efficiently conduct the heat from the cold distribution unit 2, and transfer the heat to the environment outside the computer room by liquid cooling, thereby effectively realizing a stable heat dissipation operation for the server 1. In addition, the structure of the cold distribution unit 2 in this embodiment is simple, and there is no redundant The remaining structure can indicate the evolution of higher performance; in addition, different cooling distribution units 2 can be connected to different liquid loop pipes in the computer room, so that when the liquid loop pipe in one computer room fails, water supply can be performed through other liquid loop pipes, thereby ensuring the normal operation of the liquid cooling equipment; in addition, the various components in this embodiment are connected by quick connectors and hoses, so that the whole machine can be replaced quickly by hot plugging, and maintenance can be performed quickly without stopping the machine; when any one component of at least two cooling distribution units 2 fails, the other or other cooling distribution units 2 can operate at high speed, which also ensures the normal operation of the liquid cooling equipment and further improves the stability and reliability of the use of the liquid cooling equipment.

[0120] Step S603: Control the second cooling capacity distribution unit based on the data calculation amount to ensure the heat dissipation effect on the server.

[0121] In some instances, before controlling the second cooling capacity distribution unit based on the data calculation amount, the method in this embodiment also includes: obtaining the heat dissipation capacity of the second cooling capacity distribution unit; when the heat dissipation capacity meets the heat dissipation demand corresponding to the data calculation amount, controlling the operating state of the second cooling capacity distribution unit to remain unchanged; when the heat dissipation capacity does not meet the heat dissipation demand corresponding to the data calculation amount, allowing the second cooling capacity distribution unit to be controlled based on the data calculation amount.
