[0032] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to help the understanding of the present disclosure. These should be considered in the context of the overall description and should not be considered to limit the scope of the present disclosure. Thus, those ordinarily 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 present disclosure. Also, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0033] In addition, it should be understood that the term "and / or" herein merely describes an associated relationship between associated objects, and can represent three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0034] Figure 1 A schematic diagram of the composition structure of the first embodiment 100 of the cooling system according to the present disclosure is shown in FIG. 1. Figure 1 As shown, it includes a cooling unit 11, an air cooling system 12, and a liquid cooling system 13.

[0035] The cooling unit 11 is a heat dissipation source shared by the air cooling system 12 and the liquid cooling system 13, and is configured to provide cooling liquid for the air cooling system 12 and the liquid cooling system 13, and to cool the cooling liquid returned by the air cooling system 12 and the liquid cooling system 13.

[0036] The air cooling system 12 is configured to provide air cooling for the cabinets 14 of the data center by using the cooling liquid, and the liquid cooling system 13 is configured to provide liquid cooling for the cabinets 14 by using the cooling liquid.

[0037] It can be seen that the above embodiment proposes a design scheme of a data center cooling system with air and liquid being the same source, that is, the air cooling system and the liquid cooling system share a common heat dissipation source, thereby simplifying deployment, improving compatibility, reducing energy consumption, and having good cooling effect.

[0038] In some embodiments of the present disclosure, the cooling liquid can be cooling water, which is simple and convenient to obtain. To distinguish it from other cooling water that will appear later, it can be called first cooling water, and other similar cases will not be described here.

[0039] In addition, the specific number of the cooling unit 11 can be determined according to actual needs. In some embodiments of the present disclosure, the cooling unit 11 can include a cooling tower 111 and a plate heat exchanger 112. The plate heat exchanger 112 is configured to provide first cooling water for the air cooling system 12 and the liquid cooling system 13, and to obtain first cooling water to be cooled returned by the air cooling system 12 and the liquid cooling system 13. The first cooling water to be cooled is obtained by the first cooling water absorbing heat. The second cooling water obtained from the cooling tower 111 is used to cool the first cooling water to be cooled, thereby obtaining the first cooling water. The cooling tower 111 is configured to provide second cooling water for the plate heat exchanger 112, and to obtain second cooling water to be cooled returned by the plate heat exchanger 112. The second cooling water to be cooled is obtained by the second cooling water absorbing heat. The second cooling water to be cooled is cooled to the second cooling water by heat exchange with the atmosphere.

[0040] That is, the plate heat exchanger 112 can provide first cooling water for the air cooling system 12 and the liquid cooling system 13, and can obtain first cooling water to be cooled returned by the air cooling system 12 and the liquid cooling system 13. Then, the second cooling water obtained from the cooling tower 111 can be used to cool the first cooling water to be cooled, thereby obtaining the first cooling water, and the cycle continues. That is, the plate heat exchanger 112 uses water and water heat exchange. The first cooling water is usually pure water, and the second cooling water can have relatively low requirements, such as being allowed to contain certain impurities. The first cooling water and the second cooling water will not be mixed.

[0041] The cooling tower 111 can adopt water and atmospheric (air) heat exchange mode to provide the required second cooling water for the plate heat exchanger 112, and can obtain the second to-be-cooled water returned by the plate heat exchanger 112, and obtain the second cooling water by heat exchange with the atmosphere, that is, by dissipating the heat in the second to-be-cooled water to the atmosphere, and thus circulate.

[0042] The cooling tower 111 can be an open cooling tower. It can be seen that the structure of the above-mentioned cooling unit 11 is simple and convenient to realize, and can uniformly provide the required heat dissipation cooling source for the air cooling system 12 and the liquid cooling system 13, thereby simplifying the deployment and reducing the implementation cost, etc.

[0043] In some embodiments of the present disclosure, the cooling unit 11 can further include a cooling pump 113 and a refrigeration pump 114, the cooling pump 113 is used to provide power for the water circulation between the cooling tower 111 and the plate heat exchanger 112, and the refrigeration pump 114 is used to provide power for the water circulation between the plate heat exchanger 112 and the air cooling system 12 and the liquid cooling system 13.

[0044] In combination with the above introduction, Figure 2 The schematic structure of the cooling unit 11 according to the present disclosure is shown. The number of cooling units 11 can be multiple, and the structure of each cooling unit 11 can be the same. As shown in Figure 2 The cooling pump 113 can provide power for the water circulation between the cooling tower 111 and the plate heat exchanger 112, such as by providing power to deliver the second to-be-cooled water to the cooling tower 111 and by providing power to deliver the second cooling water to the plate heat exchanger 112. Similarly, the refrigeration pump 114 can provide power for the water circulation between the plate heat exchanger 112 and the air cooling system 12 and the liquid cooling system 13. With the help of the cooling pump 113 and the refrigeration pump 114, the water circulation effect in the cooling unit 11 can be improved, and the operation stability and smoothness of the cooling unit 11 are improved.

[0045] In addition, in actual application, the cooling unit 11 can adopt N+1 configuration mode, N is a positive integer, assuming that the value of N is 3, then 4 cooling units 11 can be configured, and one of them can be used as a backup, and the other 3 can work normally. If any cooling unit 11 in operation fails, the backup can be used for replacement. In addition, the cooling unit 11 can include some other components in addition to the cooling tower 111, the plate heat exchanger 112, the cooling pump 113 and the refrigeration pump 114, that is, the auxiliary matching equipment, such as can be used for fixing or connecting, etc.

[0046] The air cooling system 12 can use the cooling liquid (such as the above-mentioned first cooling water) obtained from the cooling unit 11 to provide the air cooling heat dissipation function for the cabinet 14 of the data center.

[0047] In some embodiments of this disclosure, the operating modes of the air-cooling system 12 may include a first mode and a second mode, that is, the air-cooling system 12 can provide air-cooling heat dissipation function to the cabinet 14 according to the first mode or the second mode, which is very flexible and convenient in terms of implementation.

[0048] Figure 3 This is a schematic diagram of the composition and structure of the air-cooled system 12 described in this disclosure. Figure 3 As shown, the system includes a water-cooled condenser pump cabinet 121 and an air wall 122. The water-cooled condenser pump cabinet 121 may include a water-fluorine heat exchanger 1211, an air-suspension compressor 1212, and a liquid pump 1213. The water-fluorine heat exchanger 1211 is used to perform phase change heat exchange between gaseous refrigerant and the coolant obtained from the self-cooling unit 11 to obtain liquid refrigerant, and to return the coolant after absorbing heat to the cooling unit 11. In the first mode, the air-suspension compressor 1212 is turned on to compress the gaseous refrigerant so that the compressed gaseous refrigerant can perform phase change heat exchange with the coolant. In the second mode, the air-suspension compressor is turned off, and the liquid pump 1213 is used to provide power to send the liquid refrigerant into the air wall 122. The air wall 122 is used to return the gaseous refrigerant obtained by exchanging heat with the indoor return air and then vaporizing it to the water-fluorine heat exchanger 1211.

[0049] The refrigerant can be tetrafluoroethane (R134a), etc. In the first mode, the air-suspension compressor 1212 is turned on to compress the gaseous refrigerant. Correspondingly, the water-fluorine heat exchanger 1211 utilizes the compressed gaseous refrigerant and coolant for phase change heat exchange, thus converting the gaseous refrigerant into a liquid refrigerant. Then, the liquid refrigerant is propelled into the air wall 122 by the liquid pump 1213. In the air wall 122, the liquid refrigerant vaporizes after exchanging heat with the indoor return air, becoming a gaseous refrigerant, which is then returned to the water-fluorine heat exchanger 1211, and this cycle continues. In the second mode, the air-suspension compressor 1212 is turned off. Correspondingly, the water-fluorine heat exchanger 1211 can directly perform phase change heat exchange between the gaseous refrigerant and coolant. Other processes are the same as in the first mode and will not be described again.

[0050] Figure 4 This is a schematic diagram of the structural composition of the wind wall 122 described in this disclosure. Figure 4 As shown, it may include: a liquid inlet 1221, an electronic expansion valve 1222, and a liquid supply coil 1223. Liquid refrigerant enters the liquid supply coil 1223 after passing through the liquid inlet 1221 and the electronic expansion valve 1222 in sequence, and exchanges heat with the indoor return air in the liquid supply coil 1223. In addition, the electronic expansion valve 1222 is also used to control the opening degree of the valve according to the load of the air wall 122.

[0051] Liquid pump 1213 provides power to deliver liquid refrigerant to the inlet 1221 of the air wall 122. The liquid refrigerant then undergoes throttling via electronic expansion valve 1222, which controls the valve opening according to the load on the air wall 122 to regulate the flow rate of liquid refrigerant entering the air wall 122. After passing through the valve, the liquid refrigerant enters the supply coil 1223, where it vaporizes after heat exchange with the indoor return air, becoming gaseous refrigerant that returns to the water-fluorine heat exchanger 1211. When the load on the air wall 122 changes, the electronic expansion valve 1222 adjusts its opening accordingly.

[0052] In addition, in some embodiments of this disclosure, the number of water-cooled condenser pump cabinets 121 can be P, where P is a positive integer, and the number of air walls 122 can be M, where M is a positive integer greater than 1, and M can be L times P, where L is a positive integer greater than 1. Each water-cooled condenser pump cabinet 121 corresponds to L air walls 122.

[0053] The specific values ​​of P, M, and L can be determined according to actual needs. For example, the value of P can be 3, the value of M can be 9, and the value of L can be 3. In this case, each water-cooled condenser pump cabinet 121 corresponds to 3 air walls 122, that is, each water-cooled condenser pump cabinet 121 drives 3 air walls 122 respectively.

[0054] According to the above processing method, since each water-cooled condenser pump cabinet 121 corresponds to multiple air walls 122, the deployment method of the water-cooled condenser pump cabinet 121 can be simplified and the deployment efficiency can be improved.

[0055] In some embodiments of this disclosure, M air walls can be deployed in parallel and numbered 1 to M in a predetermined order. The predetermined order may include a left-to-right order or a right-to-left order. Accordingly, L air walls 122 corresponding to the same water-cooled condensate pump cabinet 121 may meet the following requirement: the absolute value of the difference between the numbers of any two air walls 122 is greater than 1.

[0056] As one possible implementation method, Figure 5 This is a schematic diagram showing the correspondence between the water-cooled condensate pump cabinet 121 and the air wall 122 described in this disclosure. Figure 5 As shown, it is assumed that there are 3 water-cooled condenser pump cabinets 121, namely water-cooled condenser pump cabinet a, water-cooled condenser pump cabinet b and water-cooled condenser pump cabinet c, and that there are 9 air walls 122, namely air wall 1, air wall 2, air wall 3, air wall 4, air wall 5, air wall 6, air wall 7, air wall 8 and air wall 9. The air walls can be deployed approximately evenly. Among them, water-cooled condenser pump cabinet a can correspond to air wall 1, air wall 4 and air wall 7, water-cooled condenser pump cabinet b can correspond to air wall 2, air wall 5 and air wall 8, and water-cooled condenser pump cabinet c can correspond to air wall 3, air wall 6 and air wall 9.

[0057] Taking water-cooled condensing pump cabinet a as an example, it can be seen that among the three air walls 1, 4 and 7, the numbers of any two air walls are not consecutive, that is, the absolute value of the difference between the numbers of any two air walls is greater than 1. For example, the absolute value of the difference between the numbers of air walls 1 and 4 is 3, the absolute value of the difference between the numbers of air walls 4 and 7 is also 3, and the absolute value of the difference between the numbers of air walls 1 and 7 is 6, all of which are greater than 1.

[0058] Through the above treatment, the indoor airflow can be made uniform. When a water-cooled condenser pump cabinet 121 fails, the impact on the entire room is small. This avoids, as far as possible, the rapid temperature rise and hot spots caused by the lack of a corresponding air wall 122 to deliver cold air to a cabinet 14 in a certain area.

[0059] For example, with Figure 5 Taking the water-cooled condenser pump cabinet a shown as an example, if water-cooled condenser pump cabinet a corresponds to three consecutively numbered air walls, namely air wall 1, air wall 2, and air wall 3, then if water-cooled condenser pump cabinet a malfunctions, the cabinet 14 in its corresponding area will experience a rapid temperature rise due to the lack of cold air supply, resulting in hot spots. However, if the processing method described in this disclosure is adopted, such as... Figure 5 As shown, assuming that water-cooled condenser pump cabinet a fails, due to the spacing of the air walls corresponding to each water-cooled condenser pump cabinet, some cold air (from the air walls corresponding to other water-cooled condenser pump cabinets) will still be delivered, thus delaying the occurrence of hot spot problems, etc.

[0060] The liquid cooling system 13 can use the coolant obtained from the self-cooling unit 11 to provide liquid cooling heat dissipation for the cabinet 14.

[0061] Figure 6 This is a schematic diagram of the composition and structure of the liquid cooling system 13 described in this disclosure. Figure 3 As shown, the system may include a Circuit Distribution Unit (CDU) and a secondary ring network. The Circuit Distribution Unit 131 supplies coolant from the cooling unit 11 to the secondary ring network 132, and returns the coolant after heat absorption from the secondary ring network 132 back to the cooling unit 11. The secondary ring network 132 supplies coolant to the cabinet 14 for liquid cooling, and returns the coolant after heat absorption to the Circuit Distribution Unit 131. Through the above processing, continuous liquid cooling of the cabinet 14 can be achieved.

[0062] The specific number of cooling distribution units 131 can be determined according to actual needs, and is not limited to... Figure 6 The four shown are examples. Additionally, both the cooling distribution unit 131 and the air wall 122 can be located within the air-conditioned room of the data center.

[0063] in addition, Figure 7 This is a schematic diagram illustrating the connection method between the cabinet 14 and the secondary ring network 132 described in this disclosure. Figure 7 As shown, cabinet 14 can be connected to the water pipe of secondary ring network 132 via connecting hoses and shut-off valves.

[0064] Based on the foregoing introduction, Figure 8 This is a schematic diagram of the composition of the second embodiment 800 of the cooling system described in this disclosure. For the sake of simplicity, the accompanying drawings are... Figure 8 The diagram only shows the cooling unit 11, cabinet 14, water-cooled condenser pump cabinet 121, air wall 122, cooling capacity distribution unit 131, and secondary-side ring network 132. In practical applications, cabinet 14 can be a cabinet that requires both air cooling and liquid cooling, and the number of water-cooled condenser pump cabinet 121, air wall 122, and cooling capacity distribution unit 131 can be flexibly configured according to the actual air-liquid load ratio.

[0065] The above is an introduction to the cooling system. The following embodiments of methods and devices will further illustrate the solution described in this disclosure.

[0066] Figure 9 This is a flowchart illustrating an embodiment of the air-cooled system control method described in this disclosure. Figure 9 As shown, the specific implementation methods are as follows.

[0067] In step 901, for the air-cooled system in the cooling system, the corresponding evaluation parameters are obtained; the cooling system includes: a cooling unit, an air-cooled system and a liquid-cooled system. The cooling unit serves as a common heat dissipation source for the air-cooled system and the liquid-cooled system, and is used to provide coolant to the air-cooled system and the liquid-cooled system, and to cool the coolant returned by the air-cooled system and the liquid-cooled system after absorbing heat. The liquid-cooled system is used to provide liquid cooling heat dissipation function for the data center cabinet using coolant.

[0068] In step 902, the operating mode of the air-cooling system is determined according to the evaluation parameters. The operating mode is either the first mode or the second mode. The air-cooling system is then controlled to provide air-cooling heat dissipation to the cabinet using the coolant according to the processing method corresponding to the first mode or the second mode.

[0069] By adopting the solution described in the above method embodiments, the operating mode of the air-cooled system can be adjusted according to the obtained evaluation parameters, which is very flexible and convenient, and improves the operating effect of the air-cooled system.

[0070] In some embodiments of this disclosure, obtaining the corresponding evaluation parameters may include: obtaining the outdoor wet-bulb temperature of the data center; accordingly, determining the operating mode of the air-cooled system based on the evaluation parameters may include: determining the operating mode of the air-cooled system as a first mode in response to determining that the outdoor wet-bulb temperature is greater than a predetermined threshold, and determining the operating mode of the air-cooled system as a second mode in response to determining that the outdoor wet-bulb temperature is less than or equal to a predetermined threshold.

[0071] There are no restrictions on how the outdoor wet-bulb temperature is obtained. Furthermore, the specific value of the predetermined threshold can be determined according to actual needs, such as 5 degrees Celsius. Accordingly, if the outdoor wet-bulb temperature is determined to be greater than 5 degrees Celsius, then the operating mode of the air-cooled system can be determined as the first mode; conversely, if it is less than 5 degrees Celsius, then the operating mode of the air-cooled system can be determined as the second mode.

[0072] As can be seen, the above processing method can determine the operating mode of the air-cooled system by comparing the obtained outdoor wet-bulb temperature with a predetermined threshold, which is very simple and convenient, thus laying a good foundation for subsequent processing.

[0073] In some embodiments of this disclosure, the air-cooled system may include: a water-cooled condenser pump cabinet and an air wall. The water-cooled condenser pump cabinet may include: a water-fluorine heat exchanger, an air-suspension compressor, and a liquid pump. Accordingly, controlling the air-cooled system to provide air-cooled heat dissipation to the cabinet using coolant according to the processing mode corresponding to the first mode or the second mode may include: in the first mode, turning on the air-suspension compressor, which is used to compress the gaseous refrigerant, and the water-fluorine heat exchanger is used to perform a phase change using the compressed gaseous refrigerant and the coolant from the self-cooling unit. In the first mode, the liquid refrigerant is heated to obtain liquid refrigerant. The liquid pump is used to provide power to send the liquid refrigerant into the air wall. The air wall is used to return the gaseous refrigerant obtained after the liquid refrigerant exchanges heat with the indoor return air to the water-fluorine heat exchanger. In the second mode, the air suspension compressor is turned off. The water-fluorine heat exchanger is used to use the gaseous refrigerant and coolant to perform phase change heat exchange to obtain liquid refrigerant. The liquid pump is used to provide power to send the liquid refrigerant into the air wall. The air wall is used to return the gaseous refrigerant obtained after the liquid refrigerant exchanges heat with the indoor return air to the water-fluorine heat exchanger.

[0074] In the air-liquid co-source refrigeration architecture, the liquid cooling section is 100% naturally cooled throughout the year, so it can be selected for natural cooling like the air cooling section. That is, when the outdoor wet-bulb temperature is less than or equal to 5 degrees Celsius, it is 100% naturally cooled. The operation mode is divided into mode 1 and mode 2. When the outdoor wet-bulb temperature is greater than 5 degrees Celsius, mode 1 can be run, the liquid cooling section operates normally, and the air suspension compressor of the air cooling section is turned on to improve the air cooling effect. When the outdoor wet-bulb temperature is less than or equal to 5 degrees Celsius, the air suspension compressor can be turned off to save resources due to the low outdoor temperature.

[0075] Figure 10 This is a schematic diagram of the structural composition of Embodiment 1000 of the air-cooled system control device described in this disclosure. Figure 10 As shown, it includes: an acquisition module 1001 and a control module 1002.

[0076] The acquisition module 1001 is used to acquire the corresponding evaluation parameters for the air-cooled system in the cooling system. The cooling system includes: a cooling unit, an air-cooled system, and a liquid-cooled system. The cooling unit serves as a common heat dissipation source for the air-cooled system and the liquid-cooled system, and is used to provide coolant to the air-cooled system and the liquid-cooled system, and to cool the coolant returned by the air-cooled system and the liquid-cooled system after absorbing heat. The liquid-cooled system is used to provide liquid cooling heat dissipation function for the data center cabinets using coolant.

[0077] The control module 1002 is used to determine the operating mode of the air-cooling system based on the evaluation parameters. The operating mode is either the first mode or the second mode. The control module 1002 controls the air-cooling system to provide air-cooling heat dissipation to the cabinet using the coolant according to the processing method corresponding to the first mode or the second mode.

[0078] By adopting the solution described in the above-described device embodiment, the operating mode of the air-cooling system can be adjusted according to the obtained evaluation parameters, which is very flexible and convenient, and improves the operating effect of the air-cooling system.

[0079] In some embodiments of this disclosure, the acquisition module 1001 can acquire the outdoor wet-bulb temperature of the data center, and the control module 1002 can determine the operating mode of the air-cooled system as a first mode in response to determining that the outdoor wet-bulb temperature is greater than a predetermined threshold, and can determine the operating mode of the air-cooled system as a second mode in response to determining that the outdoor wet-bulb temperature is less than or equal to the predetermined threshold.

[0080] In addition, in some embodiments of this disclosure, the air-cooled system may include: a water-cooled condenser pump cabinet and an air wall. The water-cooled condenser pump cabinet may include: a water-fluorine heat exchanger, an air-suspension compressor, and a liquid pump. In the first mode, the control module 1002 turns on the air-suspension compressor, which is used to compress the gaseous refrigerant. The water-fluorine heat exchanger is used to perform phase change heat transfer using the compressed gaseous refrigerant and the coolant from the self-cooling unit to obtain liquid refrigerant. The liquid pump is used to provide power to send the liquid refrigerant into the air wall. The air wall is used to return the gaseous refrigerant obtained after the liquid refrigerant has exchanged heat with the indoor return air and then vaporized to the water-fluorine heat exchanger. In the second mode, the control module 1002 turns off the air-suspension compressor. In the second mode, the water-fluorine heat exchanger is used to perform phase change heat transfer using the gaseous refrigerant and the coolant to obtain liquid refrigerant. The liquid pump is used to provide power to send the liquid refrigerant into the air wall. The air wall is used to return the gaseous refrigerant obtained after the liquid refrigerant has exchanged heat with the indoor return air and then vaporized to the water-fluorine heat exchanger.

[0081] In summary, by adopting the solution described in this disclosure, the air-cooled system and the liquid-cooled system can use a common heat dissipation source, thereby simplifying deployment, improving compatibility and reducing energy consumption. The air-cooled part can use water-cooled condensation phase change technology, and the liquid-cooled part can use cold plate liquid cooling technology, thereby ensuring the cooling effect, etc.

[0082] The solutions described in this disclosure can be applied to the field of artificial intelligence, particularly in areas such as internet data centers and distributed storage.
