Detailed Implementation

[0025] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The acquisition, transmission, storage, use, and processing of data in this application comply with relevant national laws and regulations. In the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solution of this application, and do not imply that the applicant has already used or necessarily used such solutions.

[0027] This invention provides a liquid cooling system that can be used to cool servers, specifically to cool the liquid-cooled cabinets of servers within a data center. In this embodiment, the data center can use liquid cooling to cool each server; therefore, each server cabinet can be configured as a liquid-cooled cabinet, meaning the server cabinets are cooled using liquid cooling.

[0028] This invention provides a liquid cooling system, such as... Figure 1 As shown, the system includes a cooling tower 11, a cooling pump 12, a first piping network 13, a second piping network 14, and at least one heat exchange structure. The cooling tower 11 is connected to the cooling pump 12 and is used to output cooling water. The cooling pump 12 is connected to both the cooling tower 11 and the first piping network 13, and is used to input the cooling water output from the cooling tower 11 into the first piping network 13. The heat exchange structure is connected to both the first piping network 13 and the second piping network 14, and is used to exchange heat between the cooling water input from the first piping network 12 and the liquid-cooled cabinet 15, and to input the heat-exchanged cooling water into the second piping network 14. The second piping network 14 is connected to the cooling tower 11 and is used to transfer the heat-exchanged cooling water to the cooling tower 11.

[0029] like Figure 1 As shown, in this embodiment of the invention, the cooling water in the cooling tower 11 is used to cool the liquid-cooled cabinet 15 corresponding to the server in the data center. The cooling tower 11 outputs cooling water, which is then transported into the first pipe network 13 by the cooling pump 12 (also called a cooling water pump). The cooling tower 11 can include various types, such as open cooling towers and closed cooling towers. In this embodiment of the invention, a closed cooling tower can be used to reduce impurities in the cooling water. The cooling pump 12 can also include various types, which can be driven by corresponding motors. Therefore, in this embodiment of the invention, the cooling pump 12 can be controlled by controlling the motor, such as opening, closing, adjusting, etc.

[0030] Since data centers typically house server clusters, they may include one or more liquid-cooled racks 15. Each liquid-cooled rack 15 can be equipped with a corresponding heat exchange structure, and each heat exchange structure is connected to a first pipe network 13 and a second pipe network 14. Cooling water is transported through the first pipe network 13 and input into the heat exchange structure. The cooling water exchanges heat with the liquid-cooled rack 15, absorbing heat from the rack and heating up, while the rack cools down due to the heat exchange. The cooled water after heat exchange is then transferred to the second pipe network 14 and returned to the cooling tower 11 for further cooling before reuse.

[0031] In this embodiment of the invention, the cooling tower 11 can be installed outdoors to fully utilize the natural outdoor cooling to lower the temperature of the cooling water in the tower. This minimizes the heat exchange process and the number of auxiliary equipment, effectively reducing the power consumption of the liquid cooling system. The specific structure of the heat exchange structure is not limited. Since it needs to exchange heat with the liquid cooling cabinet 15, it can be an annular pipe structure surrounding the liquid cooling cabinet 15 to increase the contact area with the liquid cooling cabinet 15.

[0032] In one implementation, the number of liquid-cooled cabinets 15 in the data center can be set according to the number of servers. In scenarios with a large number of liquid-cooled cabinets 15, the heat exchange structure corresponding to the liquid-cooled cabinets 15 can be connected to the first pipe network 13 and the second pipe network 14 through branch pipes. Specifically, the first pipe network 13 includes a first ring pipe and at least one first branch pipe; the second pipe network includes a second ring pipe and at least one second branch pipe; the first ring pipe is connected to the cooling water pump 12, and at least one first branch pipe is disposed in the first ring pipe and connected to the heat exchange structure; the second ring pipe is connected to the cooling tower 11, and at least one second branch pipe is disposed in the second ring pipe and connected to the heat exchange structure.

[0033] like Figure 2 As shown, in this embodiment of the invention, a ring-shaped pipe for water supply (first ring-shaped pipe) and a ring-shaped pipe for water return (second ring-shaped pipe) are provided. Branch pipes can be provided on the ring-shaped pipes, and each branch pipe is connected to a heat exchange structure for transporting cooling water. Figure 2 In this invention, valves can be installed at the connections of the first and second annular pipes with each branch pipe to control the flow direction and velocity of the cooling water transmitted through the pipes. This allows for control of the cooling water flow rate in the heat exchange structure, enabling heat exchange as needed. Furthermore, in this embodiment, each branch pipe can be configured according to the placement and number of liquid-cooled server racks within the data center. Cooling water is diverted from the first annular pipe to each of the first branch pipes, then flows into the heat exchange structure to cool the liquid-cooled server racks. After heat exchange, the cooling water flows out from each of the second branch pipes corresponding to the second annular pipe, and finally returns to the second annular pipe for transport back to the cooling tower.

[0034] In another embodiment, the liquid cooling system may further include a constant-pressure water supply device 16; the constant-pressure water supply device 16 may be installed in the second pipe network 14 for injecting cooling water into the second pipe network 14. The constant-pressure water supply device 16 is used to maintain the pressure of the liquid cooling system. In this embodiment of the invention, in order to maintain the pressure stability of the liquid cooling system, a constant-pressure water supply device 16 may be installed in the second pipe network 14 to replenish water to the liquid cooling system as needed, thereby ensuring the system pressure.

[0035] In another implementation, to monitor the operating status of the liquid cooling system, sensors can be installed in each pipeline. These sensors typically detect various parameters within the liquid cooling system to provide real-time monitoring of its operation and any malfunctions. Specifically, the sensors can include one or more of the following: temperature sensors, pressure sensors, and flow sensors. Figure 2 As shown in the embodiment of the present invention, one or more sensors, including temperature sensors, pressure sensors, and flow sensors, can be respectively installed in the first pipeline network 13 and the second pipeline network 14. This allows for real-time detection of the upper tower temperature, lower tower temperature, pressure, temperature, and flow rate of the first pipeline network 13 and the second pipeline network 14. Consequently, the fan frequency of the cooling tower 11, the motor frequency of the cooling water pump 12, and the valve opening in the pipeline can be adjusted to ensure the terminal water supply temperature and flow rate, thereby effectively dissipating heat for the liquid-cooled server.

[0036] In another embodiment, to ensure system availability, the cooling tower 11 and cooling pump 12 can be dual-configured. The cooling tower 11 includes a main cooling tower and a backup cooling tower; the cooling pump 12 includes a first cooling pump connected to the main cooling tower and a second cooling pump connected to the backup cooling tower. Figure 2 As shown, both the cooling tower 11 and the cooling water pump 12 are configured with 2N, which can minimize the impact of single-point failures and system leaks.

[0037] In this embodiment of the invention, the cooling tower in the liquid cooling system is connected to at least one heat exchange structure via a pipeline network. Cooling water can be directly transferred to the heat exchange structure, and the cooled water after heat exchange can be returned to the cooling tower. Thus, in this embodiment of the liquid cooling system, the cooling water in the cooling tower is directly transferred to the heat exchange structure, providing a direct cooling source for the liquid cooling equipment without the need for indirect heat exchange through a CDU device. This not only reduces heat loss and energy consumption but also improves the end-point cooling effect of the liquid cooling equipment.

[0038] The following is combined with Figure 1 The illustrated embodiment provides a detailed description of the control method for the liquid cooling system in this invention, used for... Figure 1 or Figure 2 The liquid cooling system is controlled, such asFigure 3 As shown, the method includes the following steps.

[0039] S301: In response to the liquid cooling system operation command, obtain the preset temperature difference of the corresponding cooling water and the preset temperature of the liquid cooling cabinet.

[0040] The liquid cooling system operation command can be triggered when the cooling system starts up. This command can include information about the liquid cooling system, and the information of each structure within the liquid cooling system can be pre-configured. Therefore, based on the operation command, the structural information corresponding to the liquid cooling system can be obtained, and thus the object to be controlled can be determined. In this embodiment of the invention, the control mainly focuses on the cooling tower and cooling pump in the liquid cooling system.

[0041] In a liquid cooling system, the temperature of the output cooling water can be controlled via a cooling tower, and the temperature difference between the first and second piping networks can be controlled via a cooling pump. When the liquid cooling system starts up, the cooling water temperature can be preset to represent the required temperature for the liquid-cooled cabinet. This allows the system to determine the required output temperature of the cooling tower, facilitating tower control based on the preset temperature. For example, a preset temperature difference can be set, representing the temperature difference of the cooling water before and after heat exchange, which can then be used to control the cooling pump.

[0042] S302: Obtain the current temperature difference between the first pipe network and the second pipe network, compare it with the preset temperature difference, determine the first adjustment direction and the first control frequency of the cooling pump based on the comparison result, generate the first control command of the cooling pump, and output the first control command to the cooling pump.

[0043] The operation of the cooling pump can be controlled by a motor. In this embodiment of the invention, the current temperature of the first pipe network and the second pipe network can be detected in real time by sensors, etc., and the current temperature difference between the first pipe network and the second pipe network can be obtained. Then, a temperature difference comparison can be preset to determine the first adjustment direction of the cooling pump. The first adjustment direction may include increasing or decreasing the motor frequency of the cooling pump. At the same time, the frequency value to be adjusted, i.e., the first control frequency, can be determined based on the difference between the current temperature difference and the preset temperature difference. Then, a first control command for the cooling pump is generated based on the first adjustment direction and the first control frequency and output to the cooling pump to control the cooling pump to operate according to the first control frequency.

[0044] It should be noted that in this embodiment of the invention, when the cooling pump is started, it usually runs to the preset lower limit of frequency first, and then the frequency can be adjusted according to the current temperature difference and the preset temperature difference. After the frequency is adjusted, if the current temperature difference is stable at the preset temperature difference, the adjusted frequency can be maintained. After a change in temperature difference is detected later, the motor frequency of the cooling pump can be adjusted again.

[0045] S303: Obtain the current temperature of the cooling water corresponding to the cooling tower, compare it with the preset temperature to determine the second adjustment direction and the second control frequency corresponding to the cooling tower, generate the second control command for the cooling tower, and output the second control command to the cooling tower.

[0046] The operation of the cooling tower can be controlled by the fan. In this step, the current temperature of the cooling water corresponding to the cooling tower can be detected in real time by sensors (usually representing the current temperature of the cooling water output by the cooling tower). The difference between the preset temperature and the current temperature can be determined, and then the second adjustment direction and the second control frequency corresponding to the cooling tower can be determined. The second adjustment direction means increasing or decreasing the frequency of the fan. After generating the second control command, it can be output to the cooling tower to control the fan of the cooling tower, thereby controlling the temperature of the cooling water output by the cooling tower.

[0047] In this embodiment of the invention, the operating status of the liquid cooling system can also be detected by a preset sensor, and the cooling tower and / or cooling pump can be adjusted in real time based on the detected real-time data.

[0048] It should be noted that, in the embodiments of the present invention, a frequency control system for the cooling pump and a frequency control system for the cooling tower can be set, so that the corresponding adjustment direction and control frequency can be determined according to the input parameters. For example, the corresponding first adjustment direction and first control frequency can be determined according to the input current temperature difference and preset temperature difference. The implementation method of determining the frequency corresponding to the adjustment direction and control frequency in the frequency control system is not limited, such as it can be implemented based on the PID control method.

[0049] Specifically, in cases of malfunction or maintenance of the liquid cooling system, a decrease in cooling water may lead to a drop in system pressure. Therefore, real-time water replenishment can be performed based on the pressure in the liquid cooling system. Specifically, this can be achieved by: detecting the pressure value corresponding to the second piping network in the liquid cooling system using a preset sensor; calculating the pressure difference based on the first pressure value and the preset pressure value to determine the corresponding water replenishment amount; generating a third control command for the corresponding constant-pressure water replenishment device and outputting it to the constant-pressure water replenishment device.

[0050] The constant-pressure water supply device can inject cooling water, thus replenishing water in real time according to pressure changes in the liquid cooling system, thereby maintaining stable pressure in the liquid cooling system. When the detected pressure value is lower than the preset pressure value, the pressure difference can be determined first, and then the corresponding water supply amount can be determined. Based on the water supply amount, a third control command is generated and output to the constant-pressure water supply device, causing the device to inject the required cooling water. The method for determining the water supply amount in this embodiment is not limited; for example, a pre-set correspondence between pressure difference and water supply amount can be used, and the water supply amount can be determined in this step by querying the correspondence based on the pressure difference.

[0051] In this embodiment of the invention, by controlling the frequency of the cooling tower and cooling pump in the liquid cooling system, the cooling water required by the liquid cooling cabinet can be directly transferred to the heat exchange structure, and the cooled water after heat exchange can be returned to the cooling tower. Thus, in this embodiment of the liquid cooling system, the cooling water in the cooling tower is directly transferred to the heat exchange structure, providing a direct cooling source for the liquid cooling equipment without the need for indirect heat exchange through a CDU device. This not only reduces heat loss and energy consumption but also improves the terminal cooling effect of the liquid cooling equipment.

Figure 1 or Figure 2 The liquid cooling system shown is as follows: Figure 4 As shown, the device 400 includes: an acquisition unit 401, configured to acquire a preset temperature difference corresponding to the cooling water and a preset temperature of the liquid cooling cabinet in response to the liquid cooling system operation command; a generation unit 402, configured to acquire the current temperature difference between the first pipe network and the second pipe network, compare it with the preset temperature difference, determine a first adjustment direction and a first control frequency of the cooling pump based on the comparison result, generate a first control command for the cooling pump, and output the first control command to the cooling pump; the generation unit 402 is further configured to acquire the current temperature of the cooling tower corresponding to the cooling water, compare it with the preset temperature, determine a second adjustment direction and a second control frequency corresponding to the cooling tower, generate a second control command for the cooling tower, and output the second control command to the cooling tower.

[0056] In this embodiment of the invention, by controlling the frequency of the cooling tower and cooling pump in the liquid cooling system, the cooling water required by the liquid cooling cabinet can be directly transferred to the heat exchange structure, and the cooled water after heat exchange can be returned to the cooling tower. Thus, in this embodiment of the liquid cooling system, the cooling water in the cooling tower is directly transferred to the heat exchange structure, providing a direct cooling source for the liquid cooling equipment without the need for indirect heat exchange through a CDU device. This not only reduces heat loss and energy consumption but also improves the terminal cooling effect of the liquid cooling equipment.
