Technical Field
[0001] The present application relates to the field of electrochemical technology, and in particular to a system, control method and equipment for providing cooling to a data center. Background Art
[0002] With the rapid development of cloud computing, big data and Internet technology, data centers have ushered in a booming development, but energy consumption has also increased. Data centers consume a lot of electricity every year. If data centers are powered by the power grid, it may cause large carbon emissions.
[0003] In order to reduce carbon emissions in the process of powering data centers, hydrogen fuel cells can be used to achieve low carbon emissions in the process of powering data centers. In order to ensure the normal use of hydrogen fuel cells, hydrogen needs to be provided to the fuel cells. However, in the process of hydrogen utilization, a key link is the storage of hydrogen. At present, the storage and transportation technology of deep-cold and high-pressure supercritical hydrogen has become a research hotspot. It combines the high volume energy density of liquid hydrogen and the phase-change-free storage advantages of gaseous hydrogen. At the same time, the temperature and pressure requirements of deep-cold and high-pressure supercritical hydrogen for containers are milder than those of ultra-low temperature liquid hydrogen and ultra-high pressure gaseous hydrogen storage. Therefore, it is considered to be one of the mainstream hydrogen storage methods in the future. However, if the working requirements of the fuel cell are met, the supercritical hydrogen needs to be heated. The current heating method is to exchange heat with the air.

[0049] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.
[0050] The acquisition, storage, use, and processing of data in the embodiments of this application comply with the relevant provisions of national laws and regulations.
[0051] First, some concepts involved in the embodiments of the present application are introduced.
[0052] Cryogenic high pressure: technology for storing fluids at higher pressures and lower temperatures. For hydrogen storage, the temperature range of cryogenic high pressure technology is generally 20-100K, and the pressure range is generally 10-50Mpa.
[0053] Supercritical hydrogen: When the temperature of hydrogen exceeds its critical temperature and the pressure exceeds its critical pressure through deep cooling and high pressure technology, it is called supercritical hydrogen. The physical and chemical properties of supercritical hydrogen are different from those of conventional gaseous hydrogen and liquid hydrogen.
[0054] Cold energy: The cold energy contained in supercritical hydrogen.
[0055] Grade: The percentage of useful components in energy. The grade of cold energy usually refers to the percentage of useful components contained in the energy. In energy utilization, high-grade energy means that it contains a higher proportion of useful components, so the energy value is also higher. For example, in thermal power generation, high-grade thermal energy can be directly converted into mechanical energy or electrical energy with high conversion efficiency, so its grade is relatively high. For cold energy, if it refers to low-temperature thermal energy, the grade may be related to the temperature of the thermal energy, that is, the percentage of low-temperature thermal energy contained in the cold energy. High-grade cold energy means that its temperature is lower and may be more suitable for certain applications that require low-temperature conditions. It should be noted that the concept of grade is not only applicable to solid and liquid mineral resources, but also to the energy field to measure the quality and applicability of energy.
[0056] Data center: A building that includes cold storage facilities, computer rooms, office areas and power supply equipment.
[0057] Power supply device: can be a fuel cell. In the embodiment of the present application, the fuel cell uses hydrogen as fuel, and the embodiment of the present application does not specifically limit it.
[0058] Cooling system: In the embodiment of the present application, the cooling system can be a cold water tank or a cold water pipe, which is not specifically limited in the embodiment of the present application. Among them, the cold water pipe can dissipate heat for the computer room of the data center.
[0059] The method for supplying power to a data center in an embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0060] Based on the problem of cooling waste in the prior art when using fuel cells to power data centers, the present application provides a control method for a control device, such as Figure 1 As shown, the method includes:
[0061] S101: When supercritical hydrogen is transmitted to a power supply device through a transmission pipeline via a plurality of hydrogen storage tanks, a first control valve between a first target area in a data center and the transmission pipeline is opened.
[0062] In the embodiment of the present application, since the power supply device of the data center is a fuel cell that uses gaseous hydrogen as energy, and in the scenario of cooling the data center, high-grade (i.e., lower temperature) cold energy is not required, the hydrogen can be stored in the form of supercritical hydrogen. The hydrogen storage tank is equipped with a flow control component, which can be controlled by a control device. The control device controls the flow control component to open, and the supercritical hydrogen in the hydrogen storage tank flows out. The pressure of the outflowing supercritical hydrogen also decreases. The larger the opening of the flow control component, the greater the flow rate.
[0063] In view of the current situation of waste of cold energy generated by supercritical hydrogen during the heating process, the embodiment of the present application proposes a solution to use this cold energy to supply cooling to the data center. The above-mentioned supercritical hydrogen flows to the power supply device through a transmission pipeline. In the process of supercritical hydrogen flowing from the hydrogen storage tank to the power supply device, the supercritical hydrogen is heated and decompressed so that the supercritical hydrogen can meet the working requirements of the power supply device when it reaches the power supply device. In other words, supercritical hydrogen will be converted into gaseous hydrogen during the transmission process. Among them, decompression can be achieved by opening the flow control component.
[0064] The temperature increase treatment can be specifically carried out as follows.
[0065] Since there are devices in the data center that generate heat during operation, such as cold storage facilities, computers, etc., the transmission pipeline in the embodiment of the present application will be connected to the first target area where the heat-generating equipment is located, so as to utilize the heat generated by the first target area to heat the supercritical hydrogen in the transmission pipeline.
[0066] Specifically, a first heat exchange component may be deployed in the transmission pipeline. For example, the first heat exchange component may be a hot water bag filled with water. The present embodiment does not specifically limit the properties of the first heat exchange component. After opening the first control valve between the first target area and the transmission pipeline, the heat in the first target area will be transferred to the water in the hot water bag, and the temperature of the hot water bag will increase, thereby heating the supercritical hydrogen in the transmission pipeline.
[0067] S102: When it is determined that the cooling capacity of the second target area of the data center is less than the preset cooling capacity, a second control valve between the second target area and the transmission channel is opened.
[0068] Supercritical hydrogen will generate cold energy during the heating process. In order to avoid wasting this cold energy, when the embodiment of the present application determines that the second target area needs cold energy, the generated cold energy will be provided to the cooling system through the refrigerant, so that the cooling system can cool down the second target area. In the embodiment of the present application, the cooling system can be a cold water pipe. The cold energy generated by supercritical hydrogen is transferred to the cooling system by opening the second control valve between the second target area and the transmission channel, which can cool down the cold water in the cold water pipe and further cool down the second target area. Among them, the first target area and the second target area can be the same or different, and the embodiment of the present application does not specifically limit it. Figure 2 As shown, the first target area can be the area where the cold storage facilities are located, the computer room and the office area, and the second target area can also be the area where the cold storage facilities are located, the computer room and the office area. The first target area and the second target area are the same.
[0069] Since supercritical hydrogen with low cold energy grade has a higher temperature and lower pressure, it has lower requirements for hydrogen storage tanks, lower costs, and higher safety. Therefore, the embodiment of the present application sets up multiple hydrogen storage tanks, and the cold energy grades of supercritical hydrogen in different hydrogen storage tanks are different, that is, the temperatures are different. The higher the grade, the lower the temperature of supercritical hydrogen. Since the temperature needs to be increased during the transmission of supercritical hydrogen, supercritical hydrogen flows from the hydrogen storage tank with high cold energy grade to the hydrogen storage tank with low cold energy grade.
[0070] For the scenario of multiple hydrogen storage tanks, the heating process of supercritical hydrogen can be implemented as follows.
[0071] For any second target area, the flow control (also called flow control assembly) on the target hydrogen storage tank corresponding to any second target area is turned on, so that the supercritical hydrogen in the target hydrogen storage tank is transmitted to the next hydrogen storage tank (not the last hydrogen storage tank) through the transmission pipeline, and the cold energy grade of the supercritical hydrogen stored in the next hydrogen storage tank is lower than that of the target hydrogen storage tank. The grade of cold energy required by any second target area matches the cold energy of the supercritical hydrogen in the target hydrogen storage tank.
[0072] like Figure 2As shown, the figure shows two hydrogen storage tanks, namely a first hydrogen storage tank and a second hydrogen storage tank, wherein the cold energy grade of supercritical hydrogen in the first hydrogen storage tank is higher than that of supercritical hydrogen in the second hydrogen storage tank, that is, the temperature of supercritical hydrogen in the first hydrogen storage tank is lower than that of the second hydrogen storage tank. The embodiment of the present application does not limit the number of hydrogen storage tanks, and can be specifically set according to the cold energy grade required by the data center.
[0073] by Figure 2 For example, the second target area of the data center that needs cold energy may include the area where the cold storage facilities are located, the computer room, and the office area. The grade of cold energy required is from high to low as cold storage facilities → computer room → office area. The supercritical hydrogen in the first hydrogen storage tank provides cold energy for the cold storage facilities, and the second hydrogen storage tank provides cold energy for the computer room and the office area.
[0074] Moreover, the cold storage facilities, computer rooms and office areas can also generate heat. When supercritical hydrogen flows out of the first hydrogen storage tank, the first control valve between the cold storage facility and the transmission pipeline will open, and the heat generated by the cold storage facility will heat up the supercritical hydrogen through the heat exchange component. The heated hydrogen will first flow into the second hydrogen storage tank, and will not directly flow into the transmission pipeline after the second hydrogen storage tank ( Figure 2 The dashed line in the figure).
[0075] Taking the second hydrogen storage tank as an example, the flow control component on the second hydrogen storage tank is opened to allow supercritical hydrogen to flow out, and the first control valve corresponding to the computer room and office area is opened to allow the supercritical hydrogen to heat up when passing through the computer room and office area. When the computer room and office area need cooling, the second control valve between the computer room and office area and the transmission pipeline is opened to allow cooling to flow into the second target area.
[0076] For scenarios where the first target area and the second target area are different, for any second target area, the first target area corresponding to the any second target area is determined, and the first target area corresponding to the any second target area is connected to a heat exchange component located in a transmission pipeline from the target hydrogen storage tank to the next hydrogen storage tank (when the target hydrogen storage tank is the last hydrogen storage tank, the first target area corresponding to the any second target area is connected to a heat exchange component located in a transmission pipeline from the target hydrogen storage tank to the power supply device); open the first control valve between the first target area corresponding to the any second target area and the transmission pipeline.
[0077] For example, in the process of backward transmission of supercritical hydrogen in the first hydrogen storage tank, it is necessary to first determine which first target areas the transmission pipeline behind the first hydrogen storage tank is connected to. When it is determined that it is connected to the cold storage facility, the first control valve between the cold storage facility and the transmission pipeline is opened, and the first control valve between the computer room and the office area and the transmission pipeline is not opened. When the cooling capacity generated by the supercritical hydrogen absorbing heat is insufficient, the cold storage facility can also be used to supply cooling to the office area and the computer room.
[0078] In addition, before opening the flow control component of the target hydrogen storage tank, it is necessary to determine whether the transmission condition is met to determine whether to open the flow control component of the target hydrogen storage tank. The judgment process is at least one of the following:
[0079] (1) Determine whether the current cooling capacity of any second area is lower than the preset cooling capacity.
[0080] When the current cooling capacity of any second area is lower than the preset cooling capacity, it indicates that any second area needs cooling capacity. At this time, it is necessary to open the flow control component of the target hydrogen storage tank so that the supercritical hydrogen heats up and absorbs heat when passing through the first target area, thereby generating cooling capacity and increasing the cooling capacity for any second target area.
[0081] (2) Determine whether the content of supercritical hydrogen in the next hydrogen storage tank of the target hydrogen storage tank is lower than the preset content. (Not for the last hydrogen storage tank, i.e., the hydrogen storage tank adjacent to the fuel cell, such as Figure 2 The second hydrogen storage tank in
[0082] Since supercritical hydrogen with low cold energy grade is easier to store, when the content of supercritical hydrogen in the low-grade hydrogen storage tank is less, supercritical hydrogen can be made to flow out from the target hydrogen storage tank.
[0083] (3) Determine whether the power of the power supply device is less than a preset power.
[0084] Since the power supply device requires hydrogen as an energy source, when the power supply device needs electricity, the flow control component of each hydrogen storage tank needs to be opened.
[0085] Based on the setting of multiple hydrogen storage tanks in the embodiment of the present application, the supercritical hydrogen in the embodiment of the present application is gradually heated up during the transmission process. Therefore, in the process from the target hydrogen storage tank to the next hydrogen storage tank (not for the last hydrogen storage tank), the supercritical hydrogen will not directly reach the temperature requirement of the fuel cell. Therefore, in the process from the target hydrogen storage tank to the next hydrogen storage tank, the supercritical hydrogen will not continue to absorb heat, and will stop receiving heat when a certain temperature is reached.
[0086] For example, in the process from the first hydrogen storage tank to the second hydrogen storage tank, the temperature of supercritical hydrogen needs to rise by a°C. When it is determined that the temperature of supercritical hydrogen has risen by a°C, the first control valve between the cold storage facility and the transmission pipeline is closed to stop the cold storage facility from providing heat to the supercritical hydrogen.
[0087] After the supercritical hydrogen is gradually heated up, it can be provided to the fuel cell. However, for the fuel cell to work, the hydrogen needs to reach a certain temperature, such as Figure 2As shown, before hydrogen flows into the fuel cell system, it is necessary to determine whether the temperature of the hydrogen has reached a certain temperature. If not, the third control valve between the fuel cell system and the transmission pipeline can be opened to use the hot water generated by the fuel cell to continue heating the hydrogen through the heat exchange component, so that the hydrogen reaches the temperature required for the fuel cell to work. After that, the fuel cell can supply power and water to the data center.
[0088] The following is based on Figure 3 The specific process of the method for supplying power to the data center is described in detail.
[0089] S301: Determine that the first storage tank stores supercritical hydrogen;
[0090] S302: Determine whether the transmission requirements of the first hydrogen storage tank are met, if yes, execute S303, otherwise, repeat S301, the transmission requirements include at least one of the following: the cold storage facility needs cold capacity, the fuel cell has sufficient power, and the supercritical hydrogen content in the second hydrogen storage tank is sufficient;
[0091] S303: Control the flow control component connected to the outflow end of the first hydrogen storage tank to open, so that supercritical hydrogen flows out of the first hydrogen storage tank;
[0092] S304: Opening the first control valve and the second control valve between the transmission channel and the cold storage facility to allow the supercritical hydrogen to exchange heat with the cold storage facility;
[0093] S305: Determine whether the transmission requirements of the second hydrogen storage tank are met, if yes, execute S307, otherwise execute S306, the transmission requirements include at least one of the following: the computer room or office area needs cooling capacity, and the fuel cell has sufficient power;
[0094] S306: Determine that the second hydrogen storage tank continues to store, and then end.

[0098] S310: Supply water and electricity to the data center, wherein the water output by the fuel cell can be used to supply water to the data center.
[0099] Based on the same inventive concept, the embodiment of the present application provides a system for supplying power to a data center, such as Figure 4a As shown, the system includes:

[0105] The first heat exchange component may be a hot water bag, and the first target area and the second target area may be the same, for example, they may be the cold storage facility 8, the machine room 8 and the office area 8. Taking the cold storage facility as an example, the heat generated by the operation of the cold storage facility 8 is transmitted to the first heat exchange component through the opened first control valve 5, so that the water in the first heat exchange component receives the heat to heat up the supercritical hydrogen in the transmission pipeline 3.

[0109] The second heat exchange component 12 is used to receive the hot water flowing out of the water output end 14 and use the heat of the hot water to heat the supercritical hydrogen in the transmission pipeline 3 .
[0110] The power supply device may be a hydrogen fuel cell, which can convert the chemical energy of hydrogen into electrical energy.
[0111] In a possible implementation, there are multiple hydrogen storage tanks, and the multiple hydrogen storage tanks include a first hydrogen storage tank 1 and at least one second hydrogen storage tank 4, and each of the second hydrogen storage tanks 4 corresponds to the first heat exchange component 7;
[0112] The first hydrogen storage tank 1 is used to store the supercritical hydrogen flowing into the hydrogen input device 2 through the inflow end 11, and to flow the supercritical hydrogen out to the transmission pipeline 3 through the outflow end 10;
[0113] The second hydrogen storage tank 4 is used to receive the supercritical hydrogen in the transmission pipeline through the corresponding first heat exchange component 7 through the inlet end 11, and to flow the stored supercritical hydrogen out to the transmission pipeline 3 through the outlet end 10, so that the supercritical hydrogen passes through the first heat exchange component 7 to the next second hydrogen storage tank, or passes through the second heat exchange component 7 to the power supply device 9.
[0114] The number of hydrogen storage tanks can be set according to the demand for cold energy quality in the data center. For example, the cold energy quality required is ranked from high to low as follows: cold storage facility 8 - computer room 8 - office area 8. However, the cold energy quality required by office area 8 and computer room 8 is not much different, so it is sufficient to set a first hydrogen storage tank and a second hydrogen storage tank. Since the cold energy quality required by computer room 8 and office area 8 is similar, the location of computer room 8 and office area 8 is not specifically limited. Figure 4a As shown, the supercritical hydrogen flowing out of the second hydrogen storage tank 4 follows the flow direction of the machine room-office area; it can also be as follows Figure 4b As shown, the supercritical hydrogen flowing out of the second hydrogen storage tank 4 follows the flow direction of the office area to the computer room; Figure 5 As shown, a second hydrogen storage tank 4 is respectively arranged before the machine room 8 and the office area 8, that is, the cold energy contained in the supercritical hydrogen in the second hydrogen storage tank 4 in front of the machine room 8 is used to cool the machine room 8, and the cold energy contained in the supercritical hydrogen in the second hydrogen storage tank 16 behind the machine room 8 is used to cool the office area 8. The embodiment of the present application does not specifically limit the order of the second target areas with the same cold energy quality requirements and the number of the second hydrogen storage tanks.
[0115] In a possible implementation, the cold energy grade required by the cold storage facility 8 is higher than the cold energy grade required by the machine room 8. Therefore, the cold energy grade of the supercritical hydrogen in the first hydrogen storage tank 1 can fully support the cooling demand of the cold storage facility 8 and the machine room 8. Figure 6 As shown, the supercritical hydrogen in the first hydrogen storage tank 1 flows out, absorbs heat when passing through the cold storage facility 8 and the machine room 8, and then provides the generated cold energy to the cold storage facility 8 and the machine room 8 respectively.
[0116] In a possible implementation, in addition to providing the cooling energy generated by supercritical hydrogen absorption to the second target area, the cooling energy can also be provided to other areas of the data center through the cold storage facilities. Figure 7 As shown, in the process of supercritical hydrogen flowing from the second hydrogen storage tank 4 to the power supply device 9, it can absorb heat through the machine room 8 and provide the generated cold energy to the machine room 8. Since the office area 8 may not always need cold energy, the supercritical hydrogen can only absorb the heat of the machine room 8 when passing through the office area 8, and does not supply cold energy to the machine room 8. Instead, when the office area needs cold energy, the cold storage facility 8 is used to supply cold energy to the office area 8.
[0117] In a possible implementation, the system includes a plurality of the first heat exchange components 7, a plurality of the first control valves 5, a plurality of the second control valves 6, a plurality of the first target areas, and a plurality of the second target areas; the first heat exchange components 7 correspond to the first target areas one-to-one, the first control valves 5 correspond to the first target areas one-to-one, and the second control valves 6 correspond to the second target areas one-to-one;
[0118] One end of the first control valve 5 is connected to the first heat exchange component corresponding to the same first target area, and the other end of the first control valve 5 is connected to the first device located in the first target area;
[0119] One end of the second control valve 6 is connected to the cooling system of the corresponding second target area, and the other end is connected to the transmission pipeline 3 .
[0120] Figure 4a In the figure, the first target area includes the area where the cold storage facility 8 is located, the machine room 8 and the office area 8. The cold storage facility 8 is connected to the corresponding first heat exchange component through the corresponding first control valve 5, and is connected to the transmission pipeline 3 through the corresponding second control valve 6; the machine room 8 is connected to the corresponding first heat exchange component through the corresponding first control valve 5, and is connected to the transmission pipeline 3 through the corresponding second control valve 6; the office area 8 is connected to the corresponding first heat exchange component through the corresponding first control valve 5, and is connected to the transmission pipeline 3 through the corresponding second control valve 6.
[0121] In a possible implementation, different first target areas may also correspond to the same first heat exchange component, such as Figure 8As shown, the machine room 8 and the office area 8 can correspond to a first heat exchange component 7, that is, the heat generated by the machine room 8 and the office area 8 are all provided to a first heat exchange component 7, and heat exchange can also be performed through the same first control valve 5 and second control valve 6. The embodiment of the present application does not specifically limit this.
[0122] In a possible embodiment, the system further comprises at least one fluidic control component 4' (ie Figure 4a The flow control assembly 4' corresponds to the hydrogen storage tank one by one;
[0123] One end of the flow control component 4' is connected to the outflow end 10 of the corresponding hydrogen storage tank, and the other end of the flow control component 4' is connected to the transmission pipeline 3 for controlling the outflow of supercritical hydrogen stored in the corresponding hydrogen storage tank.
[0124] like Figure 4a As shown, the flow control 1' corresponding to the first hydrogen storage tank 1 is used to control the outflow of supercritical hydrogen stored in the first hydrogen storage tank 1; the flow control 4' corresponding to the second hydrogen storage tank 4 is used to control the outflow of supercritical hydrogen stored in the first hydrogen storage tank 4. In addition, the flow control component can also be installed before the inflow end of the second hydrogen storage tank to control the inflow of supercritical hydrogen in the transmission pipeline 3, such as Fig. 9 As shown, a flow control 4' is provided before the inflow end 11 of the second hydrogen storage tank 4 to control the backward flow of supercritical hydrogen in the transmission pipeline 3, and this embodiment of the present application does not make any specific limitation on this.
[0125] In a possible implementation, the system further includes:
[0126] A control device is connected to the first control valve, the second control valve and the fluid control component, and is used to control the switching of the first control valve, the second control valve and the fluid control component.
[0127] like Fig.10 As shown, the control device 15 is connected to the first control valve 5 and the second control valve 6 corresponding to the cold storage facility 8, and controls the switching of the first control valve 5 and the second control valve 6; the control device 15 is connected to the flow control 4' of the second hydrogen storage tank 4, and is used to control the switching of the flow control 4'.
[0128] The embodiment of the present application is based on the demand for cold energy grades from high to low for cold storage facilities, computer room heat dissipation facilities, and office area refrigeration facilities. It adopts a cascade heat exchange method to introduce hydrogen cold energy of different grades during the heating process into the data center unit, making full use of the cold energy of deep-cold, high-pressure, supercritical hydrogen storage, while reducing the energy consumption of the data center for heat dissipation and refrigeration. In the embodiment of the present application, a multi-stage hydrogen storage facility is set up. The second hydrogen storage tank is set after the heat exchange process between the deep-cold, high-pressure hydrogen and the cold storage facility. Compared with the first hydrogen storage tank, its hydrogen storage pressure is relatively low and the temperature is relatively high, and the requirements for the container's resistance to low temperature and high pressure are relatively low. The provision of the second hydrogen storage tank reduces the time of long-term deep-cold and high-pressure storage, reduces system costs, and improves system safety.
