Detailed Implementation

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements.

[0030] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0031] With the rapid development of cloud computing technology, data centers, as the physical platform for cloud computing, have also experienced unprecedented growth globally. This rapid increase in the number of data centers has brought enormous energy costs to operators. Data center energy consumption continues to rise year by year. In particular, with the application of AI large-scale models and other technologies, server power is constantly increasing, leading to the gradual expansion of liquid cooling technology.

[0032] Existing liquid cooling systems generally consist of an outdoor side (also known as the primary side) and an indoor side (also known as the secondary side). The outdoor side includes the cooling tower, primary side piping, and primary side coolant; the indoor side includes the CDU (Coolant Distribution Unit), liquid-cooled cabinets, server equipment, secondary side piping, and secondary side coolant. The outdoor side is the external cold source, and heat transfer is mainly achieved through the rise and fall of water temperature; the indoor side includes the liquid supply loop and the internal flow channels of the server, and heat transfer is mainly achieved through the rise and fall of coolant temperature; the two parts exchange heat through plate heat exchangers in the CDU.

[0033] While existing liquid cooling systems can remove heat through two-stage heat exchange and dissipate it into the atmosphere, the heat transferred and dissipated in the environment cannot be effectively utilized. The recovery and utilization of heat from data centers is a problem that needs to be solved.

[0034] In order to overcome the shortcomings of the existing technology, after repeated thinking and verification, the inventors discovered that if the cooling tower is replaced with a water storage tank connected to the domestic water supply, heat can be collected to heat the domestic water, thereby improving the heat utilization rate. At the same time, in order to ensure the temperature control of the domestic water supply, another water storage tank can be connected for the storage and control of hot water, thereby realizing the collection and utilization of heat in the computer room, achieving the goal of energy saving, eliminating the need for a traditional cooling tower, and saving costs.

[0035] In view of this, this application provides a data center cooling device, comprising:

[0036] The cooling distribution unit includes a primary heat exchange tube and a secondary heat exchange tube. The primary heat exchange tube is provided with a primary liquid inlet and a primary liquid outlet, and the secondary heat exchange tube is used to conduct heat from the server.

[0037] The primary water storage tank is equipped with a primary water storage chamber. The primary water storage chamber is equipped with an external circulation heat exchange tube. The external circulation heat exchange tube is equipped with an external circulation inlet and an external circulation outlet.

[0038] The primary side piping network includes a primary side supply pipe and a primary side return pipe. Primary side coolant is provided in the primary side supply pipe and the primary side return pipe. The primary side supply pipe is connected to the primary side inlet and the external circulation outlet, and the primary side return pipe is connected to the primary side outlet and the external circulation inlet.

[0040] By installing a primary water storage tank on the primary side of the cooling distribution unit, with a supply and outlet for domestic water, heat generated by the server room can be collected and transferred to domestic water through heat exchange. A secondary water storage tank connected to the primary tank allows for controllable domestic water temperature, thus achieving heat collection and utilization from the server room and realizing energy conservation. Furthermore, the data center cooling device of this application eliminates the need for a traditional cooling tower on the primary side, saving costs.

[0041] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0042] Figure 1 This is one of the structural schematic diagrams of a data center cooling device provided in an embodiment of this application. Figure 2 This is a second schematic diagram of the structure of the data center cooling device provided in the embodiments of this application.

[0043] The specific structure of the data center cooling device and various possible embodiments are described in detail below.

[0044] As shown in Figure 1 The data center cooling device 100 provided by the embodiments of the present application is used in a data center.

[0045] The data center cooling device 100 comprises a cold distribution unit 10, a primary water storage tank 20, a primary side pipe network 30, and a secondary water storage tank 40. The cold distribution unit 10 is used to manage and distribute the cooling capacity in the refrigeration system to improve energy efficiency and system performance. The primary water storage tank 20 is connected to the cold distribution unit 10 through the primary side pipe network 30. The primary water storage tank 20 is used to provide domestic water, and the primary side pipe network 30 transfers the heat in the data center to the domestic water in the primary water storage tank 20 through the flow of the cooling liquid therein. The secondary water storage tank 40 is connected to the primary water storage tank 20. The secondary water storage tank 40 is used to control the liquid level and temperature of the domestic water in the primary water storage tank 20.

[0046] The cold distribution unit 10 comprises a primary side heat exchange pipe 11 and a secondary side heat exchange pipe 12. The primary side heat exchange pipe 11 and the secondary side heat exchange pipe 12 are connected through heat exchange to realize the transfer of heat. The primary side heat exchange pipe 11 is used to transfer heat to the primary water storage tank 20. The primary side heat exchange pipe 11 is provided with a primary side liquid inlet 111 and a primary side liquid outlet 112. The secondary side heat exchange pipe 12 is used to conduct the heat in the server 201.

[0047] Through the design of the primary side heat exchange pipe 11 and the secondary side heat exchange pipe 12, the system can effectively conduct and discharge the heat generated by the server 201, thereby maintaining the optimal working temperature of the server 201 and improving the cooling efficiency of the overall system.

[0048] The primary water storage tank 20 is provided with a primary water storage cavity 21. The primary water storage cavity 21 is used to store domestic water. The primary water storage cavity 21 is provided with an external circulation heat exchange pipe 22. The external circulation heat exchange pipe 22 is used to communicate with the primary side heat exchange pipe 11 to circulate the cooling liquid. The external circulation heat exchange pipe 22 is provided with an external circulation liquid inlet 221 and an external circulation liquid outlet 222. The primary water storage cavity 21 is provided with a water supply port 211, a water outlet port 212, a regulating drainage port 213, and a regulating water inlet port 214. The water supply port 211 is used to communicate with a municipal water supply pipe 202 to inject domestic water into the primary water storage cavity 21. The water outlet port 212 is used to communicate with a domestic water pipe 203 to output the heated domestic water. The regulating drainage port 213 and the regulating water inlet port 214 are respectively connected to the secondary water storage tank 40.

[0049] The primary side pipe network 30 includes a primary side liquid supply pipe 31 and a primary side liquid return pipe 32. The primary side liquid supply pipe 31 and the primary side liquid return pipe 32 are provided with a primary side cooling liquid. The primary side liquid supply pipe 31 connects the primary side liquid inlet 111 and the external circulation liquid outlet 222. The primary side liquid return pipe 32 connects the primary side liquid outlet 112 and the external circulation liquid inlet 221.

[0050] The primary side cooling liquid can circulate efficiently in the primary side of the cold energy distribution unit 10 through the primary side liquid supply pipe 31 and the primary side liquid return pipe 32, reducing energy waste and reducing pumping energy consumption through optimized fluid dynamics design.

[0051] The secondary water storage tank 40 is provided with a secondary water storage cavity 41. The secondary water storage cavity 41 is used to store heated domestic water. The secondary water storage cavity 41 is provided with a water storage port 411 and a water supplement port 412. The water storage port 411 is connected to the adjusted drainage port 213, and the water supplement port 412 is connected to the adjusted water inlet port 214.

[0052] Through the connection of the water storage port 411 and the adjusted drainage port 213, and the connection of the water supplement port 412 and the adjusted water inlet port 214, the communication between the secondary water storage tank 40 and the primary water storage tank 20 is realized, and the system can accurately control the water quantity and temperature in the primary water storage tank 20, thereby facilitating the level and temperature control of the domestic water in the primary water storage tank 20 through the secondary water storage tank 40.

[0053] The capacity of the secondary water storage tank 40 is less than that of the primary water storage tank 20. The primary water storage tank 20 water level temperature control: when the domestic water outlet is less, the liquid level of the primary water storage tank 20 is greater than the preset upper value of the liquid level interval (such as 80-90%), the water in the primary water storage tank 20 is discharged to the secondary water storage tank 40 until the liquid level decreases to the preset upper value of the liquid level interval; when the domestic water outlet is more, the liquid level of the primary water storage tank 20 is lower than the preset lower value of the liquid level interval (such as 30%), the water in the secondary water storage tank 40 is first discharged to the primary water storage tank 20, and when the secondary water storage tank 40 is emptied, the municipal water supply pipe 202 is supplied with water from an external water source to the primary water storage tank 20. The above-mentioned liquid level control controls the liquid level of the primary water storage tank 20 within the preset liquid level interval (such as 30%-80%).

[0054] The multiple secondary water storage tanks 40 contained in the system provide flexible water quantity management and storage capacity. The design of the secondary water storage tank 40 allows for expansion as needed to meet the needs of data centers and domestic water populations of different sizes. At the same time, through the combined use of the primary water storage tank 20 and the secondary water storage tank 40, the system can maintain stable cooling performance under different load conditions. The design of multiple secondary water storage tanks 40 also provides a certain redundancy capability, and when a certain secondary water storage tank 40 has a problem, other secondary water storage tanks 40 can continue to provide cooling support.

[0055] The primary side of the cold distribution unit 10 flows to the primary water storage tank 20 through the circulating pump, and the liquid of the primary side of the cold distribution unit 10 is conducted to the primary water storage tank 20 through the coil to heat the domestic water in the primary water storage tank 20. The cold distribution unit 10 controls the heat taken away by controlling the flow of the primary side refrigerant, thereby realizing the control of the inlet temperature of the secondary side of the cold distribution unit 10 to adapt to the change of the load of the secondary side server 201. The change of the flow of the primary side of the cold distribution unit 10 affects the heat conducted to the primary water storage tank 20, thereby affecting the water temperature of the primary water storage tank 20.

[0056] By providing the primary water storage tank 20 on the primary side of the cold distribution unit 10, the primary water storage tank 20 is provided with a water inlet 211 and a water outlet 212 connected to the domestic water, the heat emitted by the server 201 in the machine room can be collected and transferred to the domestic water through heat exchange, and a secondary water storage tank 40 connected to the primary water storage tank 20 is designed, so that the temperature of the domestic water is controllable, thereby realizing the collection and utilization of the heat in the machine room, realizing waste heat recovery, and achieving the purpose of energy saving. Moreover, the data center cooling device 100 of the present application does not need to configure a traditional cooling tower on the primary side, saving the cost. The cooling tower usually needs a large amount of water and electricity to operate, and saving this part of equipment can significantly reduce the operating cost. The traditional cooling tower needs a large amount of water for evaporative cooling, and this design reduces the consumption of water resources through direct heat exchange, and has higher water resource utilization efficiency.

[0057] In one possible implementation, the data center cooling device 100 further comprises an electric auxiliary heating mechanism 50. The electric auxiliary heating mechanism 50 is arranged in the primary water storage cavity 20.

[0058] The electric auxiliary heating mechanism 50 can provide additional heating capacity when needed, ensuring that the water temperature of the domestic water reaches the required level, ensuring the stability and continuity of hot water supply, which is particularly important when the heat of the server 201 is insufficient to meet the hot water demand. At the same time, the electric auxiliary heating mechanism 50 can accurately control the heating amount according to the need, avoiding excessive heating, thereby optimizing the energy efficiency. This precise control helps to reduce unnecessary energy consumption.

[0059] The water temperature control of the primary water storage tank 20 is controlled by the water inflow of the external municipal water supply pipe 202, the water inflow of the secondary water storage tank 40, the water outflow of the secondary water storage tank 40, and the heating power of the electric auxiliary heating mechanism 50. The water temperature of the primary water storage tank 20 is controlled within a range around the set value, for example, if the set value is 45 degrees, the control range is 42-48 degrees. The input variables of the system include the opening degree of the water supply adjusting valve 215 of the external municipal water supply pipe 202, the opening degree of the secondary water storage tank inflow flow adjusting valve, the opening degree of the secondary water storage tank outflow flow adjusting valve 44, and the heating power of the heating module of the electric auxiliary heating mechanism 50. The output variable of the system is the water temperature of the primary water storage tank 20. When controlling the water temperature, the opening degrees of the water supply adjusting valve 215 and the flow adjusting valve 44 are adjusted first, and the water temperature control is realized by changing the water storage capacity of the primary water storage tank 20. The electric auxiliary heating of the electric auxiliary heating mechanism 50 is performed only when the set water temperature range cannot be met through water flow control, so that energy saving can be achieved. The above-mentioned liquid level and water temperature control can use various automatic control algorithms, such as PID control, fuzzy control, and predictive control.

[0060] In a possible implementation, the data center cooling device 100 further comprises an adjusting inflow pipe 42 and an adjusting outflow pipe 43. The adjusting inflow pipe 42 is connected to the water supplement port 412 and the adjusting inflow port 214, and the adjusting outflow pipe 43 is connected to the water storage port 411 and the adjusting outflow port 213.

[0061] The design of the adjusting inflow pipe 42 and the adjusting outflow pipe 43 allows precise control of the water quantity in the primary water storage tank 20 and the secondary water storage tank 40. This precise water quantity management helps to optimize the performance of the cooling system and ensures that the system can effectively operate under different load conditions.

[0062] As shown in FIG. 4, in a possible implementation, a flow adjusting valve 44 is arranged on the adjusting inflow pipe 42 and the adjusting outflow pipe 43. Figure 2

[0063] The flow adjusting valve 44 allows precise control of the water flow, which helps to optimize the performance of the cooling system and ensures that water resources can be effectively managed under different operating conditions. By adjusting the flow, the heat exchange process can be optimized to ensure that the system operates under optimal conditions, thereby improving overall energy efficiency and reducing energy consumption. The flow adjusting valve 44 can be integrated with an automatic control system to achieve intelligent flow management, reducing the need for manual intervention and improving the operating efficiency and reliability of the system.

[0064] In a possible implementation, the water supply port 211 is connected to the municipal water supply pipe 202, and a water supply adjusting valve 215 is arranged between the municipal water supply pipe 202 and the water supply port 211.

[0065] ​The water supply regulating valve 215 allows precise control of the amount of water entering the system from the municipal water supply, helping to ensure that the system receives an appropriate supply of water under various operating conditions. By adjusting the flow, the heat exchange process can be optimized, ensuring that the system operates under optimal conditions, thereby improving overall energy efficiency and reducing energy consumption. The water supply regulating valve 215 can be integrated with an automated control system, enabling intelligent flow management and reducing the need for manual intervention, improving the efficiency and reliability of the system.

[0066] In one possible implementation, the primary water storage cavity 21 is provided with a liquid level sensor 216 and a temperature sensor 217.

[0067] The liquid level sensor 216 can monitor the water level in the primary water storage cavity 21 in real time, ensuring that the water level remains within a set range, helping to prevent pump idling due to low water level or overflow due to high water level.

[0068] The temperature sensor 217 provides real-time water temperature monitoring, ensuring that the water temperature is within the ideal range to optimize cooling efficiency and thermal energy utilization. Combined with the secondary water storage tank 40, the electric auxiliary heating mechanism 50, and the water outlet 212 flow, the water outlet temperature is stable.

[0069] The data from the liquid level sensor 216 and the temperature sensor 217 can be integrated with an automated control system to automatically adjust the water level and temperature, reducing manual intervention and improving system efficiency.

[0070] The municipal water supply pipe 202 connected to the primary water storage cavity 21 is provided with a water supply regulating valve 215, and the regulating water inlet pipe 42 and the regulating water outlet pipe 43 connected to the primary water storage tank 20 and the secondary water storage tank 40 are provided with a flow regulating valve 44. The liquid level in the primary water storage tank 20 is controlled by the flow regulating valve 44 and the water supply regulating valve 215 to cope with changes in the liquid level of the primary water storage tank 20 due to the use of hot water for daily life. The water temperature in the primary water storage tank 20 is heated by two parts, one is the cooling liquid on the primary side of the cold distribution unit 10, which conducts heat to the primary water storage tank 20 through the coil, and the second is the auxiliary heating by the electric auxiliary heating mechanism 50 when the water temperature in the primary water storage tank 20 is insufficient, to meet the temperature requirements of daily water use.

[0071] In one possible implementation, the data center cooling device 100 further comprises a liquid cooling cabinet 60 and a secondary side pipe network 70. The liquid cooling cabinet 60 is connected to the cold distribution unit 10 through the secondary side pipe network 70. The liquid cooling cabinet 60 is provided with a server 201, and the liquid cooling cabinet 60 is used to cool the server 201. The secondary side pipe network 70 transmits the cold energy provided by the cold distribution unit 10 to the liquid cooling cabinet 60 through the flow of cooling liquid therein.

[0072] The liquid cooling cabinet 60 is provided with an internal circulation heat exchange pipe 61. The internal circulation heat exchange pipe 61 is used for cooling the server 201. The internal circulation heat exchange pipe 61 is used for communication with the secondary side heat exchange pipe 12, so as to circulate the cooling liquid.

[0073] The internal circulation heat exchange pipe 61 is provided with an internal circulation liquid inlet 611 and an internal circulation liquid outlet 612. The secondary side pipe network 70 includes a secondary side liquid supply pipe 71 and a secondary side liquid return pipe 72, the secondary side liquid supply pipe 71 and the secondary side liquid return pipe 72 are provided with the secondary side cooling liquid, the secondary side heat exchange pipe 12 is provided with a secondary side liquid inlet 121 and a secondary side liquid outlet 122, and the secondary side liquid supply pipe 71 connects the secondary side liquid inlet 121 and the internal circulation liquid outlet 612. The secondary side liquid return pipe 72 connects the secondary side liquid outlet 122 and the internal circulation liquid inlet 611.

[0074] Through the secondary side liquid supply pipe 71 and the secondary side liquid return pipe 72, the secondary side of the cooling capacity distribution unit 10 is communicated, so that the secondary side cooling liquid can be circulated in it efficiently, reducing the waste of energy, and reducing the pumping energy consumption through the optimization of fluid dynamics design.

[0075] In a possible implementation, the liquid cooling cabinet 60 is provided with a liquid cooling plate, which is arranged on the server 201 and communicates with the internal circulation heat exchange pipe 61.

[0076] The liquid cooling plate belongs to indirect liquid cooling, and the cooling liquid does not directly contact the chips in the server 201. The technical principle is to install a liquid cooling plate (usually a closed cavity made of heat-conducting metal such as copper and aluminum) on the server components (such as CPU, GPU, memory, etc. High heat components), and the server components conduct heat to the liquid cooling plate through the heat-conducting components, and then use the liquid circulation inside the liquid cooling plate to transfer heat to the secondary side heat exchange pipe 12.

[0077] The liquid cooling plate directly contacts the key heat sources (such as CPU, GPU) of the server 201, can efficiently absorb and conduct heat, and provides more effective thermal management than traditional air cooling. The heat conduction capacity of the liquid is much higher than that of the air, and the liquid cooling plate can remove the heat generated by the server 201 more quickly through liquid circulation, and keep the equipment at the best working temperature.

[0078] The liquid inlet temperature of the liquid cooling cabinet 60 is 35 to 40 degrees, and the liquid outlet temperature is 40 to 50 degrees. The secondary side cooling liquid brings the heat of the liquid cooling cabinet 60 to the cooling capacity distribution unit 10, and in the cooling capacity distribution unit 10, the heat is transferred to the primary side of the cooling capacity distribution unit 10 through the coil heat exchange. By adjusting the liquid cooling flow of the primary side of the cooling capacity distribution unit 10, the inlet temperature of the secondary side of the cooling capacity distribution unit 10 is controlled.

[0079] In a possible implementation, a circulating pump is arranged in the primary side pipe network 30 and / or the secondary side pipe network 40.

[0080] The circulating pump ensures the continuous flow of cooling liquid in the pipe network, providing stable fluid circulation, thereby maintaining effective heat conduction and heat dissipation.
