Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling systems and control methods, and in particular to a liquid cooling system, control method, equipment and storage medium with air and liquid co-sourced. Background Art

[0002] In the digital age, information technologies such as cloud computing, 5G, big data, and artificial intelligence are developing rapidly, and computing power has become a new type of productivity in the digital economy era. The increase in computing power has led to a rapid increase in chip power consumption, and traditional air cooling technology is difficult to cope with the heat dissipation needs of high-power chips. Liquid cooling technology uses liquid with high specific heat capacity as a refrigerant. Its cooling capacity is 1000-3000 times that of air, and its heat conduction capacity is 25 times that of air. It can effectively solve the heat dissipation problem of high-power chips. It has become a trend to set up a liquid cooling system in the intelligent computing center to meet the heat dissipation needs.

[0003] The existing liquid cooling system mainly adopts cold plate liquid cooling, which is to place the liquid cooling heat sink close to the central processing unit (CPU) side of the server, and take away the heat dissipation of the chip in the server through the low-temperature fluid in the plate heat exchanger. However, due to the large heat dissipation of the server in the intelligent computing center, after deducting the heat solved by the cold plate liquid cooling, the remaining heat still needs to be solved by the air cooling or chilled water system. At present, the intelligent computing center using cold plate liquid cooling adopts two independent cold source systems, namely the water-cooled centralized air-conditioning system and the liquid cooling system, that is, the air-liquid cold source separation architecture. In the air-liquid cold source separation architecture, the water-cooled centralized air-conditioning system and the liquid cooling system use two independent cold source equipment, with more equipment and high maintenance costs. When deployed in stages, the flexibility of the cold source and the terminal in the air-liquid cold source separation architecture is poor, and it is difficult to meet the needs of flexible deployment.

[0043] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0045] In related technologies, most intelligent computing centers that use cold plate liquid cooling use two independent cooling source systems, namely a water-cooled centralized air conditioning system and a liquid cooling system, that is, an air-liquid cooling source separation architecture. Figure 1 As shown, Figure 1 This is a schematic diagram of the architecture of the prior art liquid cooling system. Its water-cooled centralized air conditioning system and liquid cooling system use two sets of independent cold source equipment, which has a lot of equipment. In addition, the flexibility of the cold source and the terminal is poor when deployed in stages in the air-liquid cold source separation architecture.

[0046] In view of the above technical problems, the embodiments of the present application aim to propose a liquid cooling system, control method, equipment and storage medium with the same source of air and liquid. The core concept of the present application is: the water-fluorine heat exchanger is built into the cooling distribution unit (the water-fluorine heat exchange unit can also be set separately), and the air-conditioning terminal adopts a double-coil air-conditioning terminal or a three-coil air-conditioning terminal. The double-coil air-conditioning terminal is a water heat exchange coil and an air-cooled evaporator coil, and the three-coil air-conditioning terminal is a water heat exchange coil, an air-cooled evaporator coil, and an air-cooled and dehumidified evaporator coil. The water heat exchange coil in the air-conditioning terminal is connected to the outdoor primary side cold source, and the air-cooled evaporator coil and the air-cooled and dehumidified evaporator coil are connected to the water-fluorine heat exchanger or water-fluorine heat exchange unit of the indoor cooling distribution unit. This patent realizes that the cold plate liquid cooling terminal and the air-cooled air-conditioning terminal in the machine room use the same set of outdoor primary side cold sources, and realizes infinitely adjustable cooling, which solves the problem that the traditional cold plate liquid cooling machine room needs to deploy two sets of cold sources at the same time. In addition, this patented control system coordinates the air-cooled air-conditioning system with the cold plate liquid cooling system. The cold source side has multiple pipeline connection methods such as parallel, series, and semi-series. The primary side pipeline connection method is adjusted according to the operating conditions of each air-conditioning system in the system, which improves energy saving.

[0047] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] Please refer to FIG. 2 , FIG. 2 ( a ) is a schematic diagram of a liquid cooling system with a wind-liquid homogenous structure provided in an embodiment of the present application. Figure 1 FIG. 2( a ) is a schematic diagram of a liquid cooling system with a wind-liquid homogenous structure provided in an embodiment of the present application. Figure 1 Figure 2(b) is a schematic diagram of the cold distribution unit provided in an embodiment of the present application; as shown in Figure 2(a), it includes an outdoor heat dissipation device 1, a cooling water pump 2, a cold distribution unit 3, a cold plate liquid cooling cabinet 4 and a terminal air conditioner 5.

[0049] Among them, the outdoor heat dissipation device is used to discharge the heat of the data center to the external environment; the cooling water pump provides a power source for the liquid cooling system to ensure the flow of coolant and the transfer of heat; the cold distribution unit is used to manage the distribution of coolant, and the cold distribution unit includes a liquid-cooled heat exchanger and a water-fluorine heat exchanger. The primary side of the liquid-cooled heat exchanger is connected to the outdoor heat dissipation device, and the secondary side is connected to the cold plate type liquid cooling cabinet. The primary side of the water-fluorine heat exchanger is connected to the outdoor heat dissipation device, and the secondary side is connected to the refrigerant pipe of the terminal air conditioner; the cold plate type liquid cooling cabinet is close to the high-power consumption equipment through the cold plate, and the heat is taken away by the liquid-cooled heat exchanger; the terminal air conditioner is used to control the temperature and humidity of the environment in the data center.

[0050] It can be understood that the air-liquid homologous liquid cooling system provided in the present application combines air cooling and liquid cooling into one system, and uses a cold distribution unit to centrally manage the distribution of coolant and refrigerant, thereby reducing the number and complexity of independent systems, and by sharing equipment, that is, by sharing outdoor heat dissipation devices and cooling water pumps, it reduces the duplication of equipment configuration and reduces overall costs.

[0051] Furthermore, the air-liquid homologous liquid cooling system adopts a modular design, and the outdoor heat dissipation device, cooling distribution unit and terminal air conditioner can be flexibly configured and expanded according to needs to adapt to data centers of different sizes.

[0052] Specifically, the outdoor heat dissipation device can be a closed cooling tower, an open cooling tower, a dry cooler or a plate heat exchanger or a combination thereof.

[0053] It can be understood that closed cooling towers remove heat from the liquid cooling system through a closed circulation system, avoiding direct contact between the coolant and the outside air and reducing pollution; open cooling towers remove heat by evaporating cooling water; plate heat exchangers are used to transfer heat from the cooling water in the cooling tower to the coolant in the liquid cooling system; dry coolers use air flow to directly cool the liquid and are suitable for conditions with low ambient temperatures.

[0054] In a possible implementation, the cooling capacity distribution unit further includes a compressor, a one-way valve, and a refrigerant pump; the terminal air conditioner includes an evaporator coil and an expansion valve; the compressor, the one-way valve, the refrigerant pump, the water-fluorine heat exchanger, the evaporator coil, and the expansion valve constitute a mechanical refrigeration system; and the refrigerant pump is a variable frequency pump.

[0055] In this embodiment, the cooling distribution unit integrates the liquid cooling heat exchanger and the water-fluorine heat exchanger, which simplifies the management and maintenance of the system. The mechanical refrigeration system composed of the compressor, the one-way valve and the refrigerant pump in the cooling distribution unit is also concentrated in one unit, which is convenient for unified management. In addition, the refrigerant pump is a variable frequency pump, which can dynamically adjust the flow rate according to the actual cooling demand, enhancing the flexibility and adaptability of the system.

[0056] It should be noted that, in another possible embodiment, the water-fluorine heat exchanger in the cold distribution unit can also be a separate water-fluorine heat exchange unit. Figure 3(a) is a second schematic diagram of a liquid cooling system with a wind-liquid homologous structure provided in an embodiment of the present application, and Figure 3(b) is a schematic diagram of a water-fluorine heat exchange unit provided in an embodiment of the present application. As shown in Figure 3(a), the primary side of the cold distribution unit is connected to the outdoor heat dissipation device, and the secondary side is connected to the cold plate liquid cooling cabinet. The primary side of the water-fluorine heat exchange unit is connected to the outdoor heat dissipation device, and the secondary side is connected to the refrigerant pipe of the terminal air conditioner (including the air conditioner terminal evaporator and the air conditioner terminal water heat exchange coil).

[0057] In this application, the terminal air conditioner can also use a double-coil or triple-coil air conditioner to control the temperature and humidity of the environment in the data center to ensure the suitability of the overall environment. Please refer to Figures 4(a) and 4(b). Figure 4(a) is a schematic diagram of the terminal air conditioner in the liquid cooling system with air and liquid co-source provided in the embodiment of the present application. Figure 1 4( b ) is a second schematic diagram of the terminal air conditioner in the liquid cooling system with air and liquid of the same source provided in an embodiment of the present application.

[0058] Specifically, when the terminal air conditioner is a double-coil air conditioner, the double-coil air conditioner includes a water-side heat exchange coil and a mechanical refrigeration evaporator heat exchange coil. In the double-coil terminal air conditioner, the water-side heat exchange coil is used as the main coil, and the mechanical refrigeration evaporator heat exchange coil is used as a supplementary coil of the water-side heat exchange coil. The mechanical refrigeration evaporator heat exchange coil includes a refrigerant pipe.

[0059] When the terminal air conditioner is a three-coil air conditioner, the three-coil air conditioner includes a water side heat exchange coil, a mechanical refrigeration evaporator heat exchange coil and a refrigeration and dehumidification coil, and the mechanical refrigeration evaporator heat exchange coil and the refrigeration and dehumidification coil both include refrigerant pipes.

[0060] It is understandable that the double-coil terminal air conditioner has a cooling function. When in use, the terminal air conditioner mainly uses the water-side heat exchange coil. When the cooling capacity is insufficient, the mechanical refrigeration evaporator heat exchange coil is used as a supplement to the water-side heat exchange coil. When a double-coil terminal air conditioner is used, a dehumidification system must also be set up in the machine room. The three-coil terminal air conditioner contains a water-side heat exchange coil, a mechanical refrigeration evaporator heat exchange coil, and a coil for refrigeration and dehumidification, and has both cooling and dehumidification functions. Although the cooling and dehumidification functions of a single air conditioner cannot be used at the same time, through system design and intelligent control, they can be flexibly switched in different time periods to ensure the stability of environmental conditions. In addition, the three-coil air conditioner terminal has its own humidification function (wet film humidification or electrode humidification), and there is no need to set up an additional dehumidification system, which simplifies the system structure and improves the accuracy of environmental control.

[0061] Therefore, double-coil terminal air conditioners are suitable for room-level air conditioners, row-to-row air conditioners, wind wall air conditioners, backboard air conditioners, and backboard wind wall air conditioners. Three-coil air conditioners are suitable for room-level air conditioners, row-to-row air conditioners, wind wall air conditioners, and backboard wind wall air conditioners. Among them, backboard air conditioners are not suitable for three-coil air conditioners because the number of internal coils in three-coil air conditioners is large, which has a greater impact on the size of the backboard air conditioner.

[0062] Furthermore, by introducing an intelligent control system, the operating status of each component can be monitored and adjusted in real time, energy efficiency and cooling effects can be automatically optimized, and manual intervention and operation and maintenance difficulties can be reduced.

[0063] Among them, in the cooling capacity distribution unit, the water-fluorine heat exchanger is connected to the primary system water supply end, the primary system return end, and the refrigerant pipe of the terminal air conditioner, wherein a first electric valve is arranged between the water-fluorine heat exchanger and the primary system return end; the return end of the terminal air conditioner is connected to the primary system return end, and the water supply end of the terminal air conditioner is connected to the primary system water supply end, wherein a second electric valve is arranged between the return end of the terminal air conditioner and the primary system return end; the liquid-cooled heat exchanger is connected to the primary system water supply end, the primary system return end, the secondary system water supply end and the secondary system return end, wherein a third electric valve is arranged between the liquid-cooled heat exchanger and the primary system water supply end; the primary return water pipe of the water-fluorine heat exchanger is connected to the primary water supply pipe of the liquid-cooled heat exchanger via a fourth electric valve, and the primary return water pipe of the return water end of the terminal air conditioner is connected to the primary water supply pipe of the liquid-cooled heat exchanger via a fifth electric valve.

[0064] Figure 5 The process of the control method of the liquid cooling system with air and liquid co-source provided in the embodiment of the present application Figure 1 . Figure 5 As shown, the method of this embodiment includes:

[0065] S501: Determine the water inlet temperature and water inlet flow rate of the water inlet pipe of the liquid-cooled heat exchanger, obtain the first return water temperature and the first return water flow rate of the terminal air conditioner, and obtain the second return water temperature and the second return water flow rate of the water-fluorine heat exchanger;

[0066] S502: When the first return water temperature and the second return water temperature are both greater than the inlet water temperature and the inlet water flow rate meets the preset flow rate range, a third return water temperature after the terminal air conditioner return water and the water-fluorine heat exchanger return water are mixed is obtained, and a fourth return water temperature after the terminal air conditioner return water, the water-fluorine heat exchanger return water and the cold source primary side return water are mixed is obtained;

[0067] S503: If the third return water temperature and the fourth return water temperature are both greater than the inlet water temperature, confirming that the liquid cooling system is in the first state, and adjusting the liquid cooling system to a parallel operation condition;

[0068] S504: If the third return water temperature is not greater than the inlet water temperature, and the sum of the first return water flow rate and the second return water flow rate is not less than the inlet water flow rate, confirming that the liquid cooling system is in the second state, and adjusting the liquid cooling system to a series operation condition;

[0069] S505: When the liquid cooling system is in a state other than the first state and the second state, the liquid cooling system is adjusted to a semi-series operation state.

[0070] The execution subject of the embodiment of the present application can be a server, or a control system of a liquid cooling system with air and liquid in the server, wherein the control system of the liquid cooling system with air and liquid can be implemented by software.

[0071] Furthermore, in the parallel operation condition, the first electric valve, the second electric valve, and the third electric valve are all opened, and the fourth electric valve and the fifth electric valve are all closed; in the series operation condition, the third electric valve is closed, and the other electric valves except the third electric valve are all used to adjust the flow; in the semi-series operation condition, the above electric valves are all used to adjust the flow.

[0072] It is understandable that the parallel mode is suitable for application scenarios with low energy requirements, while the full series mode and semi-series mode are suitable for application scenarios with high energy requirements. Specifically, for scenarios with low energy requirements, the parallel mode can be used without switching to the series mode; for scenarios with high energy requirements, the series-parallel mode needs to be switched according to the water temperature and flow rate.

[0073] Flow sensors and temperature sensors are installed on the return pipe of the double-coil / triple-coil air conditioner at the end, the return pipe of the water-fluorine heat exchanger, the return pipe of the primary side of the cold source, and the inlet pipe of the liquid-cooled heat exchanger.

[0074] If the return water temperature of the double-coil / triple-coil air conditioner terminal and the water-fluorine heat exchanger are both higher than the required inlet water temperature of the liquid-cooled heat exchanger, and after the return water of the double-coil / triple-coil air conditioner terminal and the water-fluorine heat exchanger are mixed with the return water of the primary side of the cold source while ensuring the inlet water flow of the liquid-cooled heat exchanger, the water temperature is still greater than the inlet water temperature of the liquid-cooled heat exchanger, then the parallel operation condition is adopted.

[0075] If the temperature of the mixed return water from the terminal of the double-coil / triple-coil air conditioner and the return water from the water-fluorine heat exchanger is not greater than the inlet water temperature of the liquid-cooled heat exchanger, and the sum of the return water flow rates from the terminal of the double-coil / triple-coil air conditioner and the return water flow rate from the water-fluorine heat exchanger is not less than the inlet water flow rate of the liquid-cooled heat exchanger, the system adopts the series operation condition.

[0076] Except for the above scenarios, the system adopts semi-series operation condition.

[0077] Figure 6 Flow chart 2 of the control method of the air-liquid co-sourced liquid cooling system provided in the embodiment of the present application. Figure 6 As shown, the method of this embodiment is applicable to a double-coil terminal air conditioner, comprising:

[0078] S601: Determine the preset supply / return air temperature range of the terminal air conditioner, and obtain the supply / return air temperature in the computer room.

[0079] S602: Determine whether the supply / return air temperature meets the preset supply / return air temperature range.

[0080] S603: If yes, the double-coil terminal air conditioner maintains the current stable operation.

[0081] S604: If not, when the supply / return air temperature is greater than the preset supply / return air temperature range, the control system calculates the total cooling capacity required by the terminal air conditioner and the cooling capacity provided by the water heat exchanger.

[0082] S605: If the cooling capacity provided by the water heat exchange coil is not less than the total cooling capacity required by the terminal air conditioner, the water heat exchange coil is operated, and the air conditioner water valve opening and fan speed are adjusted according to the supply air or return air temperature.

[0083] S606: If the cooling capacity provided by the water heat exchanger is less than the total cooling capacity required by the terminal air conditioner, operate the water heat exchanger coil, open the water valve to the maximum, operate the fluorine pump system to provide cooling for the evaporator, and adjust the fluorine pump system expansion valve opening, refrigerant pump frequency and fan speed according to the monitored supply air or return air temperature.

[0084] It is understandable that the system first determines the preset supply and return air temperature range of the terminal air conditioner. These preset values ​​are usually set according to the temperature control requirements of the computer room and the optimal operating conditions of the equipment. Next, the system obtains the current supply and return air temperatures in the computer room through sensors. The system compares the obtained supply and return air temperatures with the preset temperature range to determine whether the current temperature is within the preset range. By determining whether the temperature is within the range, potential temperature anomalies can be discovered and resolved in advance: If the current supply and return air temperatures are within the preset range, the system will maintain the existing operating state without any adjustment, avoiding unnecessary adjustments and energy consumption, and maintaining the stable operation of the system; if the current supply and return air temperatures exceed the preset range, the system will calculate the total cooling capacity required by the terminal air conditioner, and evaluate the cooling capacity that the water heat exchanger can provide, reasonably allocate and utilize cooling resources, and improve the operating efficiency of the system. In addition, through the dual cooling guarantee of the water heat exchanger and the fluorine pump system, it is ensured that the temperature can be quickly restored to the preset range, and through the dynamic adjustment of multiple parameters (expansion valve opening, refrigerant pump frequency, fan speed) Provide more refined temperature control and improve the overall performance of the system.

[0085] Figure 7 Flow chart 3 of the control method of the air-liquid co-sourced liquid cooling system provided in the embodiment of the present application. Figure 7 As shown, the method of this embodiment is applicable to a three-coil terminal air conditioner, including:

[0086] S701: Determine the preset supply / return air temperature range and the preset humidity range of the terminal air conditioner, and obtain the actual supply / return air temperature and the actual humidity in the computer room.

[0087] S702: If the actual supply / return air temperature and the actual humidity in the computer room meet the preset range, the three-coil terminal air conditioner maintains the current stable operation.

[0088] S703: When the supply / return air temperature in the machine room is greater than a preset range, the control system calculates the total cooling capacity required by the air conditioning terminal and the cooling capacity provided by the water heat exchange coil.

[0089] S704: If the cooling capacity provided by the water heat exchange coil is not less than the total cooling capacity required by the air conditioning terminal, the water heat exchange coil is operated at the air conditioning terminal, and the air conditioning water valve opening and the fan speed are adjusted according to the supply air or return air temperature.

[0090] S705: If the cooling capacity provided by the water heat exchange coil is less than the total cooling capacity required by the air-conditioning terminal, the control system calculates the cooling capacity provided by the first evaporator and the second evaporator, and determines whether to open the first evaporator or open the expansion valve in front of the first evaporator and the second evaporator at the same time. In addition, the water heat exchange coil is operated at the air-conditioning terminal, the water valve is opened to the maximum, the fluorine pump system is operated to provide cooling for the evaporator, and the fluorine pump system expansion valve opening, refrigerant pump frequency and fan speed are adjusted according to the monitored supply air or return air temperature.

[0091] S706: When the humidity in the equipment room is not greater than the preset humidity range, the three-coil terminal air conditioner adopts the humidification mode;

[0092] S707: When the relative humidity in the machine room is greater than the highest value of the preset humidity range, the standby air conditioner in each module starts the dehumidification mode and opens the expansion valve in front of the second evaporator to the maximum. When the relative humidity in the machine room meets the design parameters, the expansion valve in front of the second evaporator is closed.

[0093] It can be understood that the control method of the three-coil terminal air conditioner has more control over humidity than the control method of the two-coil terminal air conditioner. If the humidity in the machine room is lower than the preset range, the system will start the humidification mode to increase the humidity in the air. By humidification, the environmental conditions in the machine room are optimized, which is conducive to the stable operation of the equipment, ensuring that the humidity in the machine room is within an appropriate range, and preventing problems such as static electricity caused by too low humidity. If the humidity in the machine room exceeds the highest value of the preset range, the system will start the dehumidification mode of the standby air conditioner and open the expansion valve in front of the second evaporator to the maximum for dehumidification. When the humidity returns to the design parameter range, the expansion valve in front of the second evaporator is closed. Through the dehumidification mode of the standby air conditioner, the humidity in the machine room is quickly reduced to prevent equipment failure caused by excessive humidity. The system can automatically adjust the dehumidification process to ensure that the humidity is within the design parameter range and reduce manual intervention. Therefore, this embodiment can achieve precise control of the temperature and humidity of the machine room, ensure that the equipment operates in the best environment, and improve the operating efficiency and reliability of the system. At the same time, through the coordinated work of multiple adjustment means (such as water heat exchange coils, evaporators, fluorine pump systems, etc.), a more flexible and efficient temperature and humidity adjustment scheme is provided.
