[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority from Chinese Patent Application No. 202411340379.0 filed on September 25, 2024 in China, the whole content of which is incorporated herein by reference. TECHNICAL FIELD

[0004] At present, the data center cooling methods include room-level cooling, cabinet-level cooling and modular cooling, which are as follows:

[0005] Room-level cooling refers to using a room-level special air conditioning device to adjust the temperature and humidity of the whole space of the data center. The basic principle is that the air conditioning unit provides cooling capacity and mixes cold and hot air to achieve uniform average temperature. However, in the cooling process, the air flow is easily affected by the equipment or structures in the machine room, resulting in uneven temperature distribution in the machine room, large temperature difference in the vertical direction, and easy to produce local hot spots.

[0006] Cabinet-level cooling refers to the cooling components designed for each cabinet, such as cooling backboard and cooling cabinet. This cooling design requires high load-bearing capacity, high machine room height, complex overall pipeline arrangement and high construction cost for the data center.

[0007] Modular cooling refers to integrating the data center and the cooling system into a portable new type of data center, such as a container type data center. This cooling design occupies the internal space of the container, reduces the utilization rate of the container space, easily causes uneven air supply, and affects the cooling effect of the cabinet.

[0076] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0077] The following description, in conjunction with Figures 1-10, details the eddy current air storage device, air storage system, zero-energy data center, and method provided by the invention embodiments through specific implementations and application scenarios.

[0078] In a first aspect, as shown in FIG. 1, the present disclosure provides a vortex wind storage device 1, comprising: a wind storage chamber 11, and an air inlet 12 and an air outlet 13 in communication with the wind storage chamber 11; the air inlet 12 is used to collect natural wind, and the air outlet 13 is used to send wind to a machine room 9 of a zero-energy-consumption data center.

[0079] The wind storage chamber 11 is provided with a wind guide 14, which is used to guide the natural wind to circulate in the wind storage chamber 11 in the form of vortex.

[0080] It can be understood that the vortex wind storage device 1 mainly utilizes outdoor wind energy, collects natural wind continuously or intermittently input to the air inlet 12, converts the received unstable natural wind into a relatively stable wind flow in the form of vortex by the wind storage chamber 11, and then realizes refrigeration for the zero-energy-consumption data center based on the wind flow.

[0081] In order to meet the actual application requirements, the zero-energy-consumption data center is built in a high wind speed area (for example, the annual average wind speed is not less than 1.5 m / s, and the maximum wind direction wind speed is not less than 3.0 m / s), and is located in a low-density building area, so as to form a high-density utilization of the external wind environment.

[0082] The air inlet 12 and the air outlet 13 can be respectively arranged on the peripheral wall of the wind storage chamber 11 and in communication with the internal space of the wind storage chamber 11; the internal space of the wind storage chamber 11 can be configured as a columnar space, the wind guide 14 can be arranged along a helical line path and arranged on the inner wall of the columnar space, which can form a flow guide air duct extending along the helical line path on the inner wall of the columnar space; the air inlet 12 can be configured to be opposite to one end of the flow guide air duct, and the air outlet 13 can be correspondingly configured to be opposite to the other end of the flow guide air duct. In this way, when the natural wind enters the wind storage chamber 11 from the air inlet 12, the natural wind can be guided to circulate in the wind storage chamber 11 in the form of vortex by the flow guide air duct, and then output from the air outlet 13.

[0083] Of course, the wind guide 14 can also include a plurality of wind guide pieces combined in the wind storage chamber 11 to form a ring-shaped or spiral-shaped flow guide air duct in the wind storage chamber 11, which can also guide the natural wind to circulate in the wind storage chamber 11 in the form of vortex.

[0084] As can be seen, by arranging the air guide 14 in the air storage chamber 11, the natural wind is continuously collected based on the air inlet 12, and after the natural wind enters the air storage chamber 11, the air guide 14 guides the natural wind to circulate in the air storage chamber 11 in the form of vortex flow. This design converts unstable natural wind into relatively stable vortex flow, and the vortex flow gradually accumulates the kinetic energy of the subsequent received natural wind in the form of vortex flow, thereby circulating in the air storage chamber 11, achieving storage of natural wind based on the air storage chamber 11, and ensuring that the air flow can reach the machine room 9 of the zero-energy-consumption data center through the air outlet 13, meeting the cooling demand of the heat generating equipment in the machine room 9.

[0085] Compared with the room-level refrigeration, cabinet-level refrigeration or modular refrigeration for data center in the related art, the present disclosure effectively solves the problem of large energy consumption in the related art for refrigeration and cooling of the data center, and can provide a stable wind field to the data center using the collected natural wind. The device has low cost and does not consume electricity, and can achieve refrigeration and cooling of the data center, which is beneficial to ensure the refrigeration effect.

[0086] In some embodiments, as shown in FIG. 1, the air storage chamber 11 is cylindrical, and the air inlet 12 and the air outlet 13 are arranged on the side wall of the air storage chamber 11 along the tangential direction.

[0087] It can be understood that when the air storage chamber 11 is cylindrical, the internal space of the air storage chamber 11 corresponds to a cylindrical space; the air guide 14 can be arranged on the inner side wall of the air storage chamber 11 and extend along a spiral line trajectory relative to the central axis of the air storage chamber 11, so as to form a spiral flow guide channel on the inner side wall of the air storage chamber 11.

[0088] Correspondingly, the air inlet 12 and the air outlet 13 can be arranged along the horizontal direction and arranged on the side wall of the air storage chamber 11 along the tangential direction of the side wall of the air storage chamber 11; wherein the air inlet 12 can be arranged on the upper side of the air outlet 13 along the vertical direction.

[0089] Therefore, based on the above arrangement design of the air inlet 12 and the air outlet 13, in actual application, the natural wind with lower temperature enters the air storage chamber 11 along the tangential direction, and then circulates along the inner side wall of the air storage chamber 11 in the form of vortex flow under the guidance of the air guide 14, and gradually descends under the action of gravity, and finally outputs from the air outlet 13 along the tangential direction. This design not only ensures the smoothness of the air path, but also reduces the along-the-way loss generated in the process of turning and conveying the air flow in the form of vortex flow.

[0090] In some embodiments, as shown in FIG. 1, the vortex wind storage device 1 further comprises a partition 15, which is arranged in the wind storage chamber 11 to define a first wind chamber 1101 and a second wind chamber 1102 arranged side by side in the wind storage chamber 11, and the first end of the first wind chamber 1101 and the first end of the second wind chamber 1102 are communicated, and the second end of the first wind chamber 1101 and the second end of the second wind chamber 1102 are communicated.

[0093] The wind guide 14 can be arranged in at least one of the first wind chamber 1101 and the second wind chamber 1102, of course, a part of the wind guide 14 can also be arranged in the first wind chamber section and the third wind chamber section, which can ensure that the natural wind flows in the first wind chamber 1101 or the second wind chamber 1102 in the form of vortex, and the first wind chamber 1101, the third wind chamber section, the second wind chamber 1102 and the first wind chamber section are sequentially communicated to form a closed loop fluid passage, which ensures that the main flow direction of the natural wind circulates along the closed loop fluid passage.

[0094] It should be pointed out here that the first wind chamber 1101 and the second wind chamber 1102 can be provided in plurality, which can realize that the main flow direction of the natural wind sequentially passes through each first wind chamber 1101, then sequentially passes through each second wind chamber 1102, and then returns to the first wind chamber 1101 to form a circulation.

[0095] In some embodiments, as shown in FIG. 1, in order to ensure that the natural wind circulates in the wind storage chamber 11 according to the above mode, the wind guide 14 comprises a first spiral section 141, a first transition section 142, a second spiral section 143 and a second transition section 144 connected in sequence;

[0096] The first spiral section 141 is arranged in the first air chamber 1101; the first transition section 142 is arranged between the first end of the first air chamber 1101 and the first end of the second air chamber 1102; the second spiral section 143 is arranged in the second air chamber 1102; and the second transition section 144 is arranged between the second end of the second air chamber 1102 and the second end of the second air chamber 1102.

[0110] Further, the control module 6 is configured to be electrically connected with each heat generating device in the machine room 9, and the control module 6 can calculate the total heat generation of the machine room 9 according to the operating power of each heat generating device, and then convert the total heat generation of the machine room 9 into the required air volume in the machine room 9 by using the specific heat capacity formula, so as to control the regulating assembly 5 to adjust the opening degree of the wind blocking piece 4.

[0111] In some embodiments, as shown in FIG. 2, the regulating assembly 5 comprises: a bracket 51, a balance bar 52 and a balance water tank 53; the balance bar 52 is rotatably arranged on the bracket 51, the balance water tank 53 is connected with the first end of the balance bar 52, and the second end of the balance bar 52 is in transmission connection with the wind blocking piece 4; the balance water tank 53 is configured to be replenished under the control of a water supply valve K1;

[0112] The control module 6 and the water supply valve K1 are in electrical connection, and are configured to control the working state of the water supply valve K1 according to the opening degree of the wind blocking piece 4.

[0113] It can be understood that the support 51 and the balance bar 52 form a lever known in the art, the balance bar 52 has a fulcrum, and the support 51 is supported at the fulcrum; specifically, the balance bar 52 includes a first balance arm and a second balance arm connected together, and the fulcrum is located between the first balance arm and the second balance arm; wherein the first balance arm is used to support the balance water tank 53, and the second balance arm is used to be connected with the air baffle 4.

[0114] The upper side of the balance water tank 53 is provided with a water inlet pipe, and a water supply valve K1 is installed on the water inlet pipe to control the water supply to the balance water tank 53; wherein the water supply valve K1 can be an electromagnetic proportional valve.

[0115] After the control module 6 calculates the required opening degree of the air baffle 4 according to the required air volume in the machine room 9, the target weight of the balance water tank 53 can be converted according to the structural characteristics of the lever by using the moment balance formula, and then the water supply amount of the balance water tank 53 can be calculated according to the difference between the target weight and the current weight of the balance water tank 53, and finally the opening degree and opening time of the water supply valve K1 can be controlled according to the water supply amount, so as to achieve the control requirement of the water supply amount of the balance water tank 53.

[0116] Optionally, in the case that the air baffle 4 is inserted in the air outlet duct 3 in the horizontal direction, a distance measuring sensor electrically connected with the control module 6 can be arranged in the air outlet duct 3, the moving stroke of the air baffle 4 is detected by the distance measuring sensor, and the control module 6 can perform more refined control on the opening degree and opening time of the water supply valve according to the information fed back by the distance measuring sensor, so as to realize accurate control on the opening degree of the air baffle 4.

[0117] Optionally, an angle sensor can also be arranged on the balance bar 52, and the angle sensor is electrically connected with the control module 6 to monitor the inclination angle of the balance bar 52 in real time, the control module 6 can calculate the target angle of the balance bar 52 relative to the horizontal plane according to the opening degree of the air baffle 4, and then the opening degree and opening time of the water supply valve can be controlled according to the angle information fed back by the angle sensor, so as to ensure that the balance bar 52 reaches the target angle, and this design can also realize accurate control on the opening degree of the air baffle 4.

[0118] It should be pointed out that when the control module 6, the sensors and the water supply valve are provided with working power by the configured battery during the control of the regulating assembly 5, a certain amount of electric energy will be consumed, but compared with the air conditioning refrigeration mode in the related art, the amount of electric energy is relatively small, and after the opening degree of the air baffle 4 is adjusted once, the opening degree of the air baffle 4 does not need to be adjusted frequently, so the consumption of the electric energy can be ignored.

[0119] In some embodiments, as shown in FIG. 2, the regulating assembly 5 further includes an elastic member 7, and the second end of the balance bar 52 is connected with the air baffle 4 through the elastic member 7.

[0120] It can be understood that the elastic member 7 can be a spring, the second end of the balance lever 52 is connected to one end of the elastic member 7, and the other end of the elastic member 7 is connected to the wind shield 4.

[0121] When the elastic member 7 is a spring, multiple springs can be provided, and the multiple springs are arranged side by side to ensure the rigidity of the connection between the balance lever 52 and the wind shield 4, and facilitate reliable adjustment of the opening of the wind shield 4.

[0122] By arranging the second end of the balance lever 52 to be connected to the wind shield 4 through the elastic member 7, the flexible connection between the balance lever 52 and the wind shield 4 is ensured, which facilitates the transmission of the force from the balance lever 52 by the elastic member 7 to achieve the adjustment of the opening of the wind shield 4, and is also conducive to ensuring that the lever formed by the support 51 and the balance lever 52 maintains dynamic balance well, thereby enhancing the sensitivity of the opening adjustment of the wind shield 4.

[0123] In some embodiments, as shown in FIG. 2, the distance between the first end of the balance lever 52 and the fulcrum on the balance lever 52 can be greater than the distance between the second end of the balance lever 52 and the fulcrum on the balance lever 52, i.e., the length of the first balance arm of the balance lever 52 is greater than the length of the second balance arm. This design only needs to slightly change the weight of the balance water tank 53, and can adjust the opening of the wind shield 4 in a large range, thereby facilitating the reduction of the water supplement amount of the balance water tank 53 during the adjustment of the opening of the wind shield 4, and achieving the reduction of the consumption of water resources.

[0124] In some embodiments, as shown in FIG. 2, in order to facilitate the collection of natural wind, the air inlet duct 2 includes a first section 21 and a second section 22; the first end of the first section 21 is formed with a guide air inlet for collecting natural wind, and the caliber of the first end to the second end of the first section 21 gradually decreases.

[0125] The first end of the second section 22 is in communication with the second end of the first section 21, and the second end of the second section 22 is in communication with the air inlet 12.

[0126] In some embodiments, as shown in FIG. 2, the wind storage system further includes a bypass air duct 8; the first end of the bypass air duct 8 is in communication with the air inlet duct 2, and the second end of the bypass air duct 8 is in communication with the air outlet duct 3; wherein the air volume adjusting device is arranged between the second end of the bypass air duct 8 and the second end of the air outlet duct 3.

[0127] It can be understood that, due to the fluid communication between the air inlet duct 2 and the air outlet duct 3 realized by the bypass air duct 8, when the wind speed of the external natural wind is large and continuously delivered into the air inlet duct 2, part of the natural wind enters the air storage chamber 11 from the air inlet duct 2, and the other part of the natural wind enters the bypass air duct 8. The air storage chamber 11 converts the received unstable natural wind into a more stable vortex form of air flow, and this part of the air flow is mixed with the natural wind output by the bypass air duct 8, and then enters the machine room 9 of the zero-energy-consumption data center under the regulation of the air volume regulating device.

[0128] When the wind speed of the external natural wind is small and intermittently delivered into the air inlet duct 2 in a short time, the bypass air duct 8 can not deliver natural wind, at this time, the air flow stored in the air storage chamber 11 is directly output from the air outlet duct 3, and is delivered to the machine room 9 of the zero-energy-consumption data center according to the set air volume under the regulation of the air volume regulating device.

[0129] It should be pointed out here that a non-powered one-way valve plate can be arranged in the bypass air duct 8, which can be opened under the action of the wind pressure of the natural wind from the air inlet duct 2, that is, the non-powered one-way valve plate is used to limit the flow of natural wind from the air inlet duct 2 to the air outlet duct 3; correspondingly, when the air storage chamber 11 is used to deliver air alone, the non-powered one-way valve plate is used to prevent the air flow in the air outlet duct 3 from returning to the air inlet duct 2 along the bypass air duct 8.

[0130] In a third aspect, as shown in FIGS. 3 and 4, the present disclosure also provides a zero-energy-consumption data center, which comprises a machine room 9, an air supply control chamber and an air storage system as described above;

[0131] The machine room 9 has a containing space 91 and a ventilation opening 92 and a ventilation skylight 93 communicating with the containing space 91, and the containing space 91 is used to place heat generating equipment;

[0132] The air supply control chamber is arranged on one side of the machine room 9, and the air storage system is arranged in the air supply control chamber. The second end of the air outlet duct 3 in the air storage system communicates with the ventilation opening 92.

[0133] The machine room 9 and the air supply control chamber can be communicated through a switch door, and the ventilation opening 92 is arranged on the wall of the side of the machine room 9 facing the air supply control chamber.

[0134] Optionally, the east side and / or the west side of the machine room 9 can be provided with an air supply control chamber, and at least two sets of air storage systems can be arranged in each air supply control chamber.

[0135] It can be understood that, since the zero-energy consumption data center comprises the wind storage system, and the specific structure of the wind storage system refers to the above-mentioned embodiments, the zero-energy consumption data center of the present embodiment comprises all the technical solutions of the above-mentioned embodiments, and therefore at least has all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0136] Especially, since the zero-energy consumption data center cools the heat generating equipment in the machine room 9 based on the wind energy provided by the wind storage system, this cooling design realizes effective utilization of outdoor wind energy, and compared with the room-level refrigeration, cabinet-level refrigeration and modular refrigeration adopted by the data center in the related art, has the following beneficial effects:

[0137] (1) The zero-energy consumption data center no longer uses conventional air conditioning equipment to cool the machine room 9, no longer considers the problem of occupying the limited internal space of the machine room 9 by the air conditioning equipment, and does not need to configure corresponding power equipment for the air conditioning equipment, thereby greatly improving the utilization rate of the machine room 9;

[0138] (2) The energy for cooling of the zero-energy consumption data center comes from the outdoor natural cold source, and does not consume electric power energy, so that the electric power energy only needs to bear the power load of the information technology (IT) equipment, lighting, monitoring and communication functions in the machine room 9, the air conditioning power load is zero, and the power usage effectiveness (PUE) value can be reduced to below 1.05;

[0139] (3) Since the zero-energy consumption data center does not configure conventional air conditioning equipment, its construction cost and operation and maintenance cost are much lower than those of the related art, it is green and energy-saving in the whole life cycle, the total cost of ownership (TCO) value is low, and zero-carbon emission of the zero-energy consumption data center in cooling is realized.

[0140] When constructing the zero-energy consumption data center, firstly, the external environment and climate information are integrated, judged, and comprehensively analyzed, and the internal use function and environmental demand are comprehensively analyzed; on the basis of comprehensive analysis, the building shape construction mainly responds to the external environment and climate conditions, regulates the external wind environment around the zero-energy consumption data center and shapes the shape beneficial to internal ventilation. Secondly, the internal layout construction undertakes the basic framework of the building shape, and directly responds to the internal function and its environmental regulation demand.

[0141] The comprehensive analysis of the construction of zero-energy consumption data center includes three parts: the outside of data center, the inside of data center and other influencing factors. In the analysis of the outside of data center, the annual monthly temperature, wind weather information, surrounding artificial structures and natural environment factors need to be collected. In the site selection of data center, the construction in high wind speed and low density building area should be considered to form high density utilization of external wind environment. In the analysis of the inside of data center, the owner and use demand, size and function type need to be investigated to meet the construction of zero-energy consumption data center under different calculation network and different calculation power requirements. It should be pointed out that in the severe cold and cold regions of China, due to the characteristics of low temperature in the outdoor wind environment all year round, the technical scheme has all-year usability, that is, the region of the construction of zero-energy consumption data center meets the following conditions: the annual average wind speed is greater than the set wind speed value, the density of surrounding building group is lower than the set density value, and the annual average temperature is lower than the set temperature value.

[0142] In some examples, the zero-energy consumption data center can be located in the low-density building area in the suburb of Hohhot, with the specific latitude and longitude of 40°49'N, 111°41'E;

[0143] Meteorological conditions: annual average temperature 7.2℃;

[0144] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0145] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0146] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0147] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0148] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0149] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0150] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0151] The average wind speed of the most frequent wind direction in summer is 3.4m / s.

[0152] At the same time, the zero-energy consumption data center can be configured to face north with a westward deviation of 30°, and the building size of the zero-energy consumption data center is 60×15×17m (length×width×height). The wind storage system is arranged on the east and west sides of the zero-energy consumption data center, and the size of the corresponding air supply control room is 5×15×8m (length×width×height).

[0153] The zero-energy data center can regulate the path, flow, direction and speed of the outdoor wind field by the external shape design and arrangement combination. The regulation of the building shape to the air flow follows the basic principle of air flow. When considering the air flow of the surrounding environment, the zero-energy data center can be considered as an obstacle of the wind at a local or larger regional scale. The air must move around the obstacle or pass through the obstacle. Therefore, the construction of the building shape of the zero-energy data center and its orientation and position play a decisive role in achieving zero cooling energy consumption.

[0154] Fig. 5 schematically shows the air flow characteristics caused by a surface of the zero-energy data center after the surface is blown by the incoming environmental wind perpendicular to the surface. According to Fig. 5, the outdoor air flow field is essentially generated because the zero-energy data center hinders the air flow, which generates wind pressure on the windward surface and becomes the power to drive the air (natural wind) into the machine room 9 inside the zero-energy data center. When the air moves along the designed flow path and is finally discharged from the machine room 9 of the zero-energy data center, the zero-energy data center achieves free cooling.

[0155] In the application scenario of the present disclosure, the building shape of the zero-energy data center adopts the principle of east-west large surface width and north-south small longitudinal depth, the ratio of the length of the machine room 9 along the east-west direction to the length of the machine room 9 along the north-south direction is not less than 3:1, and the wind storage system is arranged on the east side and / or west side of the machine room 9; for example, the wind storage system is arranged on the east side and west side of the machine room 9; at the same time, the building orientation of the zero-energy data center is controlled within the range of 45±5 degrees with respect to the dominant wind direction of the summer season in the region where the zero-energy data center is located.

[0156] In some embodiments, in order to ensure the reliability of the cooling of the machine room 9, the wind storage system is provided with multiple sets, and at least one of the multiple sets of wind storage systems serves as a standby wind storage system. That is, the standby wind storage system does not work normally, and the other wind storage systems are in working state.

[0157] Specifically, the zero-energy data center can be configured with four sets of wind storage systems, two of which are arranged on the west side of the machine room 9, and the air outlet ducts 3 of the two sets of wind storage systems are in communication with the ventilation openings 92 arranged on the outer wall of the west side of the machine room 9; the other two sets are arranged on the east side of the machine room 9, and the air outlet ducts 3 of the two sets of wind storage systems are in communication with the ventilation openings 92 arranged on the outer wall of the east side of the machine room 9.

[0158] Among them, the set of wind storage systems located on the west side of the machine room 9 forms a one-to-one standby redundant design, and the set of wind storage systems located on the east side of the machine room 9 also forms a one-to-one standby redundant design.

[0159] In some embodiments, as shown in FIG. 3 and FIG. 4, a plurality of top plates 10 are arranged in the accommodation space 91 from top to bottom, and the plurality of top plates 10 divide the accommodation space 91 into a plurality of compartments, and the plurality of compartments are in fluid communication;

[0160] According to the arrangement order of the compartments from bottom to top, the power of the heat generating equipment stored in each compartment gradually increases; and the air exhaust window 93 is in communication with one of the plurality of compartments located at the uppermost layer.

[0161] According to the arrangement order of the compartments from bottom to top, the plurality of compartments are sequentially in fluid communication; and the plurality of compartments are provided with the air vents 92 except for the one located at the uppermost layer. Each compartment can be provided with a plurality of air vents 92 to ensure balanced cooling of each compartment.

[0162] It can be understood that the vortex wind storage device 1 converts the unstable natural wind outside into a stable wind field required by the machine room 9, and delivers the stable wind field to the working area in the machine room 9 through the air vents 92 to utilize the low-temperature airflow to conductive heat dissipation for the heat generating equipment located in the working area, and then discharges the heat-exchanged gas from the air exhaust window 93.

[0163] By providing the air vents 92 in the plurality of compartments except for the one located at the uppermost layer, cold air can be delivered to each compartment below the uppermost layer through each air vent 92, so that an air pressure difference is formed between each compartment at the bottom and the compartment at the top, and the principle of hot air rising and cold air sinking is utilized. The cold air received in the compartments at different heights is heated by the heat generating equipment in the corresponding compartments, so that temperature difference and density difference are generated, thereby generating free air power to push the hot air in the working area to be discharged to the outside through the air exhaust window 93.

[0164] Since, according to the arrangement order of the compartments from bottom to top, the power of the heat generating equipment stored in each compartment gradually increases, the temperature difference and the density difference of the air in the different compartments arranged in the height direction increase, and this design is more conducive to the flow of gas from bottom to top along each compartment, avoiding the accumulation of heat in one or more compartments.

[0165] Alternatively, two top plates 10 are arranged in the accommodation space 91 from top to bottom, and the two top plates 10 divide the accommodation space 91 into three compartments, the heat generating equipment placed in the compartment at the lowest layer is high-low voltage power distribution cabinet, power battery and monitoring equipment, the heat generating equipment placed in the compartment at the middle layer is a general server, and the heat generating equipment placed in the compartment at the top layer is an intelligent server.

[0166] In some embodiments, as shown in FIG. 3, in order to facilitate the control of the air supply area for air supply into the intermediate room, at least one air deflector 300 is arranged on the inner side of the air vent 92, and the air deflector 300 is arranged horizontally or obliquely upward; and / or for the air vent 92 of each layer of the intermediate room, the height of the air vent 92 relative to the ground surface of the intermediate room is 300-1500mm.

[0167] Specifically, the air deflector 300 is rotatably arranged on the inner side of the air vent 92, and the included angle of the air deflector 300 relative to the inner wall surface of the machine room 9 can be adjusted between 0-90° to realize the oblique upward air supply into the intermediate room.

[0168] Further, the air deflector 300 can be provided with three air deflectors, the first air deflector 300 is arranged horizontally, the second air deflector 300 is arranged vertically upward, and the third air deflector 300 is arranged obliquely upward and located between the first air deflector 300 and the second air deflector 300.

[0169] In some embodiments, as shown in FIG. 3, in order to ensure the cleanliness of the air in the machine room 9, a filter assembly 200 is arranged on the outer side of the air vent 92, and the filter assembly 200 is used for filtering the air flow entering the containing space 91. Wherein, the filter assembly 200 can be a filter screen or a filter grid known in the art.

[0170] In some embodiments, as shown in FIG. 6, the top plate 10 comprises: a storage area 1001 and a hollow area 1002; the storage area 1001 is used for storing heat generating equipment, and the hollow area 1002 is used for realizing the fluid communication between the intermediate rooms of adjacent two layers;

[0171] Wherein, in the vertical direction, the projection of the storage area 1001 of each top plate 10 overlaps, and the projection of the hollow area 1002 of each top plate 10 overlaps.

[0172] It can be understood that the storage area 1001 can be paved with a steel plate with a size of 600*600mm, and be subjected to anti-seismic and reinforcement to meet the safety of the heat generating equipment layout. The hollow area 1002 can be paved with a hollow module with a size of 600*600mm, and the hollow module is in a grid shape, and the size of a single mesh in the hollow module is 50*50mm.

[0173] As shown in FIG. 6, by arranging the projection of the storage area 1001 of each top plate 10 overlapping in the vertical direction, and the projection of the hollow area 1002 of each top plate 10 overlapping, this design can ensure that each intermediate room forms a vertical through gas passage based on the hollow area 1002 in the vertical direction, and can avoid the accumulation of heat in each intermediate room. Wherein, FIG. 6 uses arrows to show the flow direction of the gas passing through the hollow area 1002 from bottom to top.

[0174] In some embodiments, as shown in Figures 3 and 7, the zero-energy data center further includes: a self-venting heat dissipation cabinet 100; the self-venting heat dissipation cabinet 100 has a heat dissipation channel that runs through the length of the self-venting heat dissipation cabinet 100; multiple heat-generating devices are provided, and the multiple heat-generating devices are arranged sequentially along the heat dissipation channel. In Figure 7, arrows are used to indicate the direction of gas flow along the heat dissipation channel.

[0175] In practical applications, the self-ventilating heat-generating rack 100 houses general-purpose or intelligent computing servers. The self-ventilating heat-generating rack 100 employs a rack-along layout, with cable trays directly integrated into the upper side of the rack. Adjustable air deflectors can be installed on the outer facade of the rack to ensure smooth airflow within the rack. The interior of the self-ventilating heat-generating rack 100 adopts a transparent design (eliminating partitions between adjacent racks, allowing for continuous flow). Air ducts are built into the parallel U-shaped spaces between the servers, thus delivering air into the rack's internal cavity. The airflow over the server surfaces achieves cooling, replacing the function of the rack's own server fans and realizing the rack's self-ventilating heat function.

[0176] In a fourth aspect, as shown in Figure 8, this disclosure also provides a control method for a zero-energy data center as described above, comprising the following steps:

[0177] Step 810: Obtain the operating power of each heat-generating device in the work area of ​​the computer room and the air supply temperature of the eddy current air storage device;

[0178] Step 820: Calculate the total heat generation of the working area based on the operating power of each heat-generating device;

[0179] Step 830: Calculate the required air volume for the working area based on the difference between the total heat generation and the set temperature and supply air temperature of the working area.

[0180] Step 840: Adjust the opening of the wind deflector according to the required air volume using the control and regulation components.

[0181] Understandably, in order to ensure effective cooling of the computer room, according to the principle of energy balance, the cooling capacity input to the vortex air storage device should be greater than or equal to the total heat generation of the working area. Thus, the minimum required air volume of the working area can be calculated based on the total heat generation of the working area.

[0182] The total heat generation of the working area is set to Q. 总 The total heat generation in the working area is Q. 总 This is the sum of the operating power of each heat-generating device.

[0183] According to the specific heat capacity formula: Q 总 =M 总 C p (t R -t0);

[0184] In the above formula: C p The specific heat at constant pressure of air is 1.005 kJ / (kg·℃); t R t0 is the supply air temperature of the vortex wind storage device, which is 7.2℃.

[0185] The required air volume M of the working area can be obtained from the above formula 总 .

[0186] Further, in the case that multiple sets of wind storage systems are configured in the machine room, and each set of wind storage system corresponds to the situation of supplying air to the machine room through multiple air vents, the step of controlling the regulating assembly to adjust the opening degree of the wind blocking piece according to the required air volume in the present disclosure comprises:

[0187] According to the required air volume, the air supply volume of each set of wind storage system is determined;

[0188] According to the air supply volume of the wind storage system, the target opening degree of the wind blocking piece in the wind storage system is determined;

[0189] According to the target opening degree of the wind blocking piece, the opening degree of the wind blocking piece is adjusted by the regulating assembly, so that the opening degree of the wind blocking piece reaches the target opening degree.

[0190] According to the target opening degree of the wind blocking piece, the target angle of the balance bar relative to the horizontal plane can be calculated, and then according to the angle information fed back by the angle sensor, the opening degree and opening time of the water supply valve can be controlled to ensure that the balance bar reaches the target angle, thereby realizing accurate control of the opening degree of the wind blocking piece.

[0191] Fig. 9 shows a schematic diagram of the physical structure of an electronic device, as shown in Fig. 9, which can include a processor 910, a communications interface 920, a memory 930 and a communications bus 940, wherein the processor 910, the communications interface 920 and the memory 930 communicate with each other through the communications bus 940. The processor 910 can call the logical instructions in the memory 930 to execute the control method of the zero-energy data center, which comprises: obtaining the running power of each heat generating device in the working area in the machine room and the supply air temperature of the vortex wind storage device; calculating the total heat generation of the working area according to the running power of each heat generating device; calculating the required air volume of the working area according to the difference between the total heat generation, the set temperature of the working area and the supply air temperature; and controlling the regulating assembly to adjust the opening degree of the wind blocking piece according to the required air volume.

[0192] Further, the logic instructions in the memory 930 described above can be implemented in the form of software functional units and sold or used as independent products, and can be stored in a computer readable storage medium. Based on such understanding, the technical solutions of the disclosure essentially or the parts that contribute to the related art or parts of the technical solutions can be embodied in the form of a software product. The computer software product is stored in a storage medium, and includes a plurality of instructions for causing a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the disclosure. The aforementioned storage medium includes: a U disk, a mobile hard disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a magnetic disk or an optical disk, and various media that can store program codes.

[0193] In a fifth aspect, as shown in FIG. 10, the disclosure also provides an optimization method of the zero-energy data center as described above, comprising the following steps:

[0194] Step 110, obtaining the absolute temperature of the air inside and outside the computer room, the height difference of the exhaust skylight and the ventilation opening of the computer room, and the wind speed inside the computer room;

[0195] Step 120, calculating the thermal pressure air power of the computer room according to the difference between the absolute temperatures of the air inside and outside the computer room and the height difference, calculating the wind pressure air power of the computer room according to the air density of the ventilation opening and the wind speed inside the computer room, and obtaining the total air power of the computer room according to the sum of the thermal pressure air power and the wind pressure air power;

[0196] Step 130, obtaining the air resistance inside the computer room according to the total air power of the computer room;

[0197] Step 140, adjusting the corresponding ventilation components of the computer room according to the air resistance, so that the current air resistance inside the computer room is less than the total air power; wherein the ventilation components include the filter assembly and the air deflector provided in the ventilation opening, and the self-heat-removal cabinet located inside the computer room.

[0198] It can be understood that, in order to ensure that the cold air can be used to dissipate heat for the zero-energy data center, power balance calculation needs to be performed to check whether the air power meets the requirements.

[0199] In actual application, the thermal pressure air power P of the computer room is calculated by using the following formula based on the principle of fluid mechanics 热 ; P 热 =h(ρ0-ρ R )=K s h(1 / T0-1 / T R );

[0200] In the above formula, h is the height difference of the exhaust air window and the vent of the machine room, in units of m;

[0201] ρ0 is the air density at the vent, in units of kg / m 3 ; ρ R is the air density at the exhaust air window, in units of kg / m 3 ;

[0202] T0 is the absolute temperature of the air at the vent, in units of K; T R is the absolute temperature of the air in the machine room, in units of K;

[0203] K s is a coefficient related to the setting air pressure of the zero-energy data center, taking 1017.9 kPa·K / m.

[0204] At the same time, the wind pressure aerodynamic force P 风 of the machine room is calculated according to the following formula: P 风 = Kρv / 2;

[0205] In the above formula, K is the aerodynamic force coefficient set for the zero-energy data center, taking 300; ρ is the air density in the machine room of the zero-energy data center at the set temperature, in units of kg / m 3 ; and v is the average flow rate of the air in the machine room of the zero-energy data center, in units of m / s.

[0206] Therefore, the total aerodynamic force P 总 of the machine room is P 热 + P 风 .

[0207] To ensure the normal air cooling requirement of the zero-energy data center, the air resistance in the machine room should be less than the total aerodynamic force P 总 of the machine room. The total air resistance of the filter assembly, the air deflector, the self-heat-removal cabinet, and the structures in the machine room can be calculated, which is the maximum resistance along the path of the air from the vent to the exhaust air window. Therefore, according to the total air resistance, each vent component can be selectively configured, and the vent component that does not meet the air resistance requirement can be replaced to meet the air flow requirement of the zero-energy data center.

[0208] In some embodiments, the optimization method of the zero-energy data center provided by the present disclosure further includes:

[0209] acquiring the dust concentration in the air in the machine room;

[0210] in the case that the dust concentration is greater than a preset value, outputting a prompt information of replacing the filter assembly at the vent.

[0211] It can be understood that by setting a PM2.5 sensor at the air vent, the PM2.5 sensor is a device specially designed to detect the concentration of particulate matter with a diameter less than or equal to 2.5 microns in the air, and the PM2.5 sensor is used to collect the dust concentration entering the machine room through the air vent.

[0212] When the dust concentration is greater than the preset value, a prompt message can be sent to the user, such as a live voice prompt to replace the filter assembly, or a prompt message to replace the filter assembly at the air vent is sent to the user's terminal device to prompt the user to replace the filter assembly at the air vent in time, ensuring that the dust concentration in the air in the machine room is less than the preset value.

[0213] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present disclosure, and not to limit them; although the present disclosure has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
