Description

Technical Field

[0001] This specification relates to the field of energy conservation and emission reduction technology, and in particular to a data center heat dissipation system, method, and corresponding data center. Background Technology

[0002] Data center equipment continuously generates heat during operation. Typically, data centers are equipped with cooling systems to maintain a constant temperature and ensure normal equipment operation. However, existing cooling systems are large-scale and high-power, with air conditioning units and fans consuming enormous amounts of electricity around the clock, leading to huge electricity costs. In some regions with consistently low temperatures, outdoor natural cold sources can meet the cooling needs of data centers. Therefore, there is an urgent need for a low-energy-consumption cooling system for data centers that utilizes outdoor natural cold sources without requiring chiller units, cooling towers, or other equipment, thereby reducing the overall energy consumption of the data center and lowering its daily electricity costs. Summary of the Invention

[0149] Figure 1 This is a schematic diagram of a data center heat dissipation system 1 provided in an embodiment of the present invention. The device may include: a data center server room 100, a heat dissipation device 101, a natural cold air inlet channel 102, a hot air exhaust channel 103, an air monitor 104, and a controller 105. The heat dissipation device 101 is located inside the data center server room 100; the natural cold air inlet channel 102 and the hot air exhaust channel 103 are respectively connected to the heat dissipation device 101; the air monitor 104 is used to monitor the air quality of the outdoor natural air; the controller 105 is used to control the working mode of the natural cold air inlet channel 102 and / or the hot air exhaust channel 103 according to the air quality, so as to perform adaptive heat dissipation inside the data center server room 100.

[0150] The embodiments of this specification connect the heat dissipation equipment inside the data center server room 100 to the natural cold air intake channel 102 and the hot air exhaust channel 103 respectively. Based on the real-time outdoor air quality obtained by the air monitor 104, the controller 105 controls the working mode of the natural cold air intake channel 102 and / or the hot air exhaust channel 103 according to the air quality. This enables the use of outdoor natural cold air to dissipate heat inside the data center server room 100, reducing the power consumption and power cost of the data center, reducing pollution caused by power consumption, and switching the working mode of the data center heat dissipation system 1 in real time according to the constantly changing air quality to improve the utilization rate and effect of outdoor natural cold air. At the same time, when the temperature of the outdoor natural wind is insufficient to dissipate heat inside the data center server room 100, the corresponding working mode is quickly activated to ensure that the heat generated inside the data center server room 100 can always be effectively discharged to the outside.

[0151] Specifically, in some embodiments, during the operation of a data center, related equipment such as network switches and server clusters continuously generate heat. Simultaneously, the normal operation of these devices is subject to strict requirements of the surrounding environment; for example, the ambient temperature cannot be too high, otherwise it will affect the performance of the equipment or even damage it. Currently, existing data centers often install large air conditioning systems inside the server room to dissipate the heat generated by these devices. However, large air conditioning systems consume extremely high amounts of electricity, resulting in high costs and significant carbon emissions and environmental pollution. To minimize the power consumption of data centers while protecting the environment and reducing carbon emissions, this invention proposes setting up data centers in areas with consistently low temperatures throughout the year and using outdoor natural fresh air to cool the data center server room, thereby ensuring the normal operation of the related equipment within the data center. Furthermore, when existing data centers encounter power outages or other problems, they often activate backup power supplies to power the related equipment and large air conditioning systems. In this case, compared to data centers that utilize outdoor natural air for cooling, the backup power supplies consume power much faster.

[0152] See attached document Figure 2a In some embodiments, the hot air exhaust duct 103 may include: a first exhaust port 201, a hot air exhaust valve 202, and an exhaust fan 203. The first exhaust port 201 is connected to the hot air exhaust valve 202 and the exhaust fan 203 respectively; the hot air exhaust valve 202 is used to adjust the opening degree of the hot air after heat exchange to the outside under the control of the controller 105, and to adjust the pressure difference between the inside and outside; the exhaust fan 203 is used to make the hot air flow from the inside of the data center computer room to the outside.

[0153] Specifically, in some embodiments, the hot air exhaust duct 103 is used to exhaust the hot air generated after heat exchange under the control of the controller 105. Specifically, a first exhaust port 201 is provided so that the hot air can be discharged from the first exhaust port 201. At the same time, in order to adjust and control the flow rate of the discharged hot air or control the pressure difference between the indoor and outdoor areas, a hot air exhaust valve 202 is also provided. In some embodiments, the hot air exhaust valve 202 can be embedded in the first exhaust port 201, or it can be located in front of the first exhaust port 201 along the air flow direction. This is not limited in this document. This allows the opening of the valve to be adjusted under the control of the controller 105 to discharge the hot air after heat exchange to the outside. In order to facilitate the smooth flow and discharge of hot air, an exhaust fan 203 is also provided. (See attached figure) Figure 2b As shown, the exhaust fan 203 also operates under the control of the controller 105. In some embodiments, the exhaust fan 203 can also switch the exhaust intensity under the control of the controller 105.

[0154] See attached document Figure 3In some embodiments, the natural cold air intake channel 102 may include: a first air inlet 301, a cold air intake valve 302, a mixing box 303, and a blower 304. The cold air intake valve 302 is connected to both the first air inlet 301 and the mixing box 303; the mixing box 303 is connected to the blower 304; the first air inlet 301 is used to introduce the outdoor natural air into the data center cooling system 1; the cold air intake valve 302 is used to adjust its opening under the control of the controller 105 to allow the outdoor natural air to flow into the mixing box 303; the mixing box 303 is used to regulate the airflow; and the blower 304 is used to deliver the regulated air into the data center computer room 100.

[0155] It can be understood that, in some embodiments, the natural cold air inlet channel 102 is used to introduce outdoor natural cold air with air quality meeting preset standards into the data center computer room under the control of the controller 105, or to introduce outdoor natural cold air with air quality not meeting preset standards into the data center computer room after being processed by the natural cold air inlet channel 102, or to activate the cooling equipment built into the natural cold air inlet channel 102 to perform internal air circulation cooling in the data center computer room. In other words, the natural cold air inlet channel 102 is used to switch different working modes of the natural cold air inlet channel 102 under the control of the controller 105 to provide cold air to the inside of the data center computer room 100.

[0156] In some embodiments, the natural cold air intake channel 102 may specifically include a first air inlet 301 for introducing outdoor natural air into the data center cooling system 1. In some embodiments, the first air inlet may be an air inlet louver, and may also include a cold air intake valve 302 for adjusting the valve under the control of the controller 105 to allow outdoor natural air to flow into the mixing box 303 for sorting airflow. In order to smoothly deliver outdoor natural air into the data center computer room 100 (to provide power for delivering outdoor natural air into the data center computer room 100), a blower 304 is provided. In some embodiments, the blower 304 may also switch the air supply intensity under the control of the controller 105, thereby realizing the introduction of outdoor natural cold air with air quality meeting preset standards into the data center computer room.

[0157] Further, refer to the appendix Figure 4In some embodiments, the natural cold air inlet channel 102 may further include: a spray module 401, a first spray chamber 4011, a second spray chamber 4012, a return air heat exchange module 402, a first return air heat exchange chamber 4021, a second return air heat exchange chamber 4022, an auxiliary cooling air valve module 403, a first auxiliary cooling air valve 4031, a second auxiliary cooling air valve 4032, and a third auxiliary cooling air valve 4033. The first spray chamber 4011 is connected to the first air inlet and the cold air inlet valve 302 to spray and cool the outdoor air. The first auxiliary cooling valve 4031 is connected to the second return air heat exchange chamber 4022 and the second spray chamber 4012. The second spray chamber 4012 is connected to the mixing box 303 to sequentially perform return air heat exchange and spray cooling on the return air inside the data center computer room 100. The second auxiliary cooling valve 4032 is connected to the second return air heat exchange chamber 4022 and the mixing box 303 to perform return air heat exchange on the return air. The third auxiliary cooling valve 4033 is connected to the air outlets of the first return air heat exchange chamber 4021 and the first spray chamber 4011 to perform return air heat exchange on the return air and discharge outdoor air. (Continued as attached...) Figure 4 As shown, the first return air heat exchange chamber 4021 and the second return air heat exchange chamber 4022 are adjacent to each other and are connected by a heat dissipation plate 404; the air valve in the auxiliary cooling air valve module 403 adjusts its opening degree under the control of the controller 105.

[0158] It can be understood that, in some embodiments, the natural cold air inlet channel 102 is used to introduce outdoor natural cold air whose air quality does not meet the preset standard into the data center computer room after being processed by the natural cold air inlet channel 102 under the control of the controller 105. Alternatively, when the cooling equipment built into the natural cold air inlet channel 102 is activated to perform internal air circulation cooling in the data center computer room, the outdoor natural cold air whose air quality does not meet the preset standard or the internal air circulation cooling in the data center computer room is achieved by controlling the spray module 401, the return air heat exchange module 402 and the auxiliary cooling air valve module 403. Specifically, the spray module includes at least a first spray chamber 4011 and a second spray chamber 4012, used to spray air to reduce its temperature and effectively purify it, removing dust and solid floating debris. In some embodiments, the spray chambers also dehumidify the air. The principle is that when hot air encounters cold air, the moisture in it condenses. The air in the spray chamber can be considered as hot air. When the ambient temperature drops to a certain level, the gaseous water in the hot air turns into liquid and is carried away from the hot air. Although the water accumulation in the spray chamber increases, the moisture in the air decreases, thus achieving dehumidification. Furthermore, the equipment inside the data center server room 100 generally requires that the ambient humidity not be too high. Under humid conditions, the equipment in the data center may experience changes in appearance or deterioration in physical, chemical, and electrical properties, leading to functional failure. The spraying action of the spray chambers can protect the equipment inside the data center server room 100.

[0159] In some embodiments, the return air heat exchange module 402 includes at least a first return air heat exchange chamber 4021 and a second return air heat exchange chamber 4022, for exchanging heat between air and return air heat exchange equipment in the return air heat exchange chambers. In some typical embodiments, the first return air heat exchange chamber 4021 is used to exchange heat with the second return air heat exchange chamber 4022. The first return air heat exchange chamber 4021 and the second return air heat exchange chamber 4022 are adjacent to each other and are connected by a heat sink 404. When outdoor natural cold air is discharged through the first return air heat exchange chamber 4021 through the third auxiliary cooling air valve 4033, the indoor air of the data center computer room flows after heat exchange in the second return air heat exchange chamber 4022. The air is directed to the second spray chamber 4012 or the mixing box 303. At this time, the second return air heat exchange chamber 4022 absorbs heat from the indoor air, while the first return air heat exchange chamber 4021 does not absorb heat from the air. The overall temperature of the first return air heat exchange chamber 4021 is lower than that of the second return air heat exchange chamber 4022. On this basis, the air in the first return air heat exchange chamber 4021 and the second return air heat exchange chamber 4022 is still in a flowing state. Thus, the second return air heat exchange chamber 4022 and the first return air heat exchange chamber 4021 exchange heat through the heat dissipation plate 404, so that the first return air heat exchange chamber 4021 can discharge the absorbed heat to the outside, thereby improving the heat dissipation capacity of the return air heat exchange module 402.

[0160] In some embodiments, the auxiliary cooling damper module 403 includes at least a first auxiliary cooling damper 4031, a second auxiliary cooling damper 4032, and a third auxiliary cooling damper 4033, used to connect the spray module 401 and the return air heat exchange module 402 with their corresponding components in the natural cold air inlet channel 102, so as to achieve spray cooling and / or return air heat exchange treatment after outdoor natural air flows in, and to meet the air circulation requirements. The specific location of each damper in the auxiliary cooling damper module 403 is not limited herein. Continuing as... Figure 4 As shown, in some embodiments, when indoor return air enters the return air heat exchange chamber through the first auxiliary cooling air valve 4031 or the second auxiliary cooling air valve 4032, the first auxiliary cooling air valve 4031 and the second auxiliary cooling air valve 4032 can be provided with two air inlets and two corresponding air valves respectively. For ease of installation, they can also share one air inlet and share the same air valve.

[0161] See attached document Figure 5 In some embodiments, the second auxiliary cooling air valve 4032 is disposed above the first auxiliary cooling air valve 4031.

[0162] It can be understood that, in some embodiments, the second auxiliary cooling air valve 4032 is connected to the second return air heat exchange chamber 4022 and the mixing box 303 respectively, while the first auxiliary cooling air valve 4031 is connected to the second return air heat exchange chamber 4022 and the second spray chamber 4012 respectively. The second spray chamber 4012 is connected to the mixing box 303. That is to say, the air flowing out from the first auxiliary cooling air valve 4031 is first sprayed by the second spray chamber 4012 and then sent into the mixing box 303 for airflow sorting. Relatively speaking, the air connected to the first auxiliary cooling air valve 4031 is mostly sprayed by the second spray chamber 4012. In order to facilitate the discharge of water sprayed by the second spray chamber 4012, the second spray chamber 4012 is set on the ground instead of suspended. Accordingly, the second auxiliary cooling air valve 4032 is set above the first auxiliary cooling air valve 4031, thereby facilitating the layout of the second spray chamber 4012.

[0163] See attached document Figure 6 In some embodiments, each spray chamber includes: a water pump 601, a spray pipe 602, a nozzle 603, a second air inlet 604, a second air outlet 605, and a baffle plate 606. The water pump 601 is connected to the spray pipe 602; the nozzles 603 are installed at equal intervals at the spray pipe 602; the second air outlet 605 is located on the opposite side away from the second air inlet 604; the baffle plate 606 is located in front of the second air outlet 605 to prevent water splashing into the second air outlet 605.

[0164] It can be understood that, in some embodiments, the spray chamber may specifically include a water pump 601, which is used to deliver water or increase water pressure under the control of the controller 105. The spray pipe 602 is connected to the water pump 601 and the nozzle 603 respectively. When the controller 105 turns on the spraying state of the nozzle, it drives the water pump to deliver water or increase water pressure so that water flows out from the nozzle 603 through the spray pipe 602. In some embodiments, the nozzles 603 are installed at equal intervals at the spray pipe to help the water be sprayed evenly, thereby making the air sprayed evenly and ensuring the spraying effect. The spray chamber also needs to be equipped with a second air inlet 604 and a second air outlet 605 to allow air to flow in and out respectively. In some embodiments, the distance between the two is relatively far, in order to maximize the space occupied by the spray area and thus improve the spray cooling and dust removal effect. At the same time, in order to prevent water splashing into the second air outlet 605, a baffle plate 606 is provided on the front side of the second air outlet 605, and a blower 304 provides air flow power so that the sprayed air can smoothly enter the mixing box 303.

[0165] In some embodiments, the water pump 601 controls the spraying state of the nozzle 603 under the control of the controller 105.

[0166] It can be understood that, in some embodiments, under the control of the controller 105, the water pump 601 can turn the spraying state of the nozzle 603 on or off by delivering water or increasing the water pressure.

[0167] See attached document Figure 7 In some embodiments, there are multiple baffles 606 arranged at equal intervals, and their array direction is parallel to the plane where the air outlet is located; the baffles 606 are provided with corrugated drainage channels 701 for diverting airflow.

[0168] It can be understood that in some embodiments, multiple baffles 606 are arranged at equal intervals, and their array direction is parallel to the plane where the air outlet is located. Compared with a single baffle device, this helps to better prevent water splashing. Compared with baffles arranged at random intervals and in an array direction, the baffles 606 in the embodiments of this specification are easier to install and can effectively avoid the problem of water splashing caused by uneven spacing, which results in excessively large or small spacing. In some embodiments, in order to make the water on the baffles 606 flow down in an orderly manner as quickly as possible, the baffles 606 are provided with corrugated drainage channels 701 for drainage.

[0169] In some embodiments, a water collection ditch is provided on the lower side of the baffle plate, and the water collection ditch is connected to a drain pipe to drain the spray chamber.

[0170] It can be understood that, in some embodiments, the water flowing down from the baffle can be collected by a water collection ditch and then flowed out through a drain pipe connected to the water collection ditch, thereby avoiding water residue in the spray chamber.

[0171] See attached document Figure 8 In some embodiments, each return air heat exchange chamber includes: a heat exchanger 801, a third air inlet 802, and a third air outlet 803. The heat exchangers 801 are evenly distributed in an array in the return air heat exchange chamber; the third air outlet 803 is located at a diagonal position away from the third air inlet 802.

[0172] It can be understood that, in some embodiments, the heat exchangers 801, which are evenly distributed in an array in each return air heat exchange chamber, facilitate airflow. The heat exchangers 801 can be air-to-air heat pipe heat exchangers, which have the advantages of lightweight structure and easy installation. The third air inlet 802 and the third air outlet 803 are used to allow air to flow in and out, respectively. The third air outlet 803 is located at a diagonal position away from the third air inlet 802, which helps to allow air to flow and exchange heat in the largest possible space in the return air heat exchange chamber. In some embodiments, the exhaust fan 203 in the hot air exhaust duct 103 provides the power for airflow in the first return air heat exchange chamber.

[0173] In some embodiments, the fins of the heat exchanger are inclined; the heat pipes of the heat exchanger are V-shaped.

[0174] It can be understood that, in some embodiments, the inclined fins facilitate airflow on both sides, reducing fan resistance loss, and the V-shaped heat pipes facilitate increasing the heat exchange area and improving the heat exchange effect.

[0175] In some embodiments, the heat sink is a corrugated plate.

[0176] It can be understood that, in some embodiments, the corrugated heat sink helps to increase the heat exchange area and enhance the heat exchange effect.

[0177] In some embodiments, the air quality monitoring results include values ​​for air temperature, humidity, inhalable particulate matter, total volatile organic compounds, and the concentration of harmful gases.

[0178] It can be understood that, in some embodiments, in addition to humidity and temperature, it is also necessary to monitor the values ​​of inhalable particulate matter, total volatile organic compounds, and the gas concentration of harmful gases in order to avoid harm to personnel and equipment in the data center.

[0179] In some embodiments, the controller 105 is configured to control the operating mode of the natural cold air inlet duct 102 and / or the hot air exhaust duct 103 according to the air quality, including:

[0180] The operating modes include a first heat dissipation mode, a second heat dissipation mode, and a third heat dissipation mode;

[0181] The first heat dissipation mode includes a first sub-mode and a second sub-mode;

[0182] The second heat dissipation mode includes a third sub-mode, a fourth sub-mode, and a fifth sub-mode;

[0183] The third heat dissipation mode includes a sixth sub-mode and a seventh sub-mode;

[0184] The controller 105 switches between various sub-modes in the first heat dissipation mode, the second heat dissipation mode, and the third heat dissipation mode according to the air quality control, and further includes:

[0185] If all indicators in the air quality monitoring results except for temperature are less than the corresponding first threshold, then the first heat dissipation mode is activated.

[0186] After the first heat dissipation mode is activated, if the temperature is less than the first temperature threshold, the first sub-mode is activated; otherwise, the second sub-mode is activated.

[0187] If all indicators in the air quality monitoring results except temperature are not less than the first threshold and are not greater than the corresponding second threshold, then the second heat dissipation mode is activated.

[0188] After the second heat dissipation mode is activated, if the temperature is less than the second temperature threshold, the third sub-mode is activated; if the temperature is not less than the second temperature threshold and not greater than the third temperature threshold, the fourth sub-mode is activated; if the temperature is greater than the third temperature threshold, the fifth sub-mode is activated.

[0189] If at least one indicator other than temperature in the air quality monitoring results is greater than the second threshold, then the third heat dissipation mode is activated;

[0190] After the third heat dissipation mode is activated, if the temperature is less than the fourth temperature threshold, the sixth sub-mode is activated; otherwise, the seventh sub-mode is activated.

[0191] In some embodiments, the controller 105 switches between different operating modes of the natural cold air inlet channel 102 and / or the hot air exhaust channel 103 under different air quality conditions. When the air quality is high (humidity, concentration of inhalable particulate matter, concentration of harmful gases, etc. are all lower than preset values), the controller 105 switches to the first heat dissipation mode. Specifically, when the temperature is also lower than the preset value (which can be understood as a low temperature state), the first sub-mode is selected; when the temperature is not lower than the preset value (which can be understood as a high temperature state), the second sub-mode is selected. When the air quality is moderate (at least one of the indicators such as temperature and humidity is lower than the preset value but all indicators are not higher than another preset value, and at the same time the concentration of inhalable particulate matter, concentration of harmful gases, etc. are not higher than the preset value), the controller 105 switches to the first heat dissipation mode. When the temperature is below the preset value, the controller 105 selects the second heat dissipation mode. Specifically, when the temperature is also below the preset value (which can be understood as a low-temperature state), the controller selects the third sub-mode. When the temperature is not below the preset value but not above another preset value (which can be understood as a medium-temperature state), the controller selects the fourth sub-mode. When the temperature is above another preset value (which can be understood as a high-temperature state), the controller selects the fourth sub-mode. When the air quality is low (one of the following indicators is greater than the preset value: humidity, concentration of inhalable particulate matter, concentration of harmful gases, etc.), the controller 105 switches to the third heat dissipation mode. Specifically, when the temperature is below the preset value (which can be understood as a low-temperature state), the controller selects the sixth sub-mode. When the temperature is not below the preset value (which can be understood as a high-temperature state), the controller selects the seventh sub-mode. This allows the controller 105 to switch between the sub-modes of the first, second, and third heat dissipation modes under different air quality conditions, ensuring that the performance of equipment in the data center is not damaged, the safe activities of staff are not affected, and improving heat dissipation performance.

[0192] It should be noted that the data centers and data center cooling systems described in the embodiments of this specification are located in areas with low temperatures throughout the year. The above-mentioned medium and high temperatures are relative to low temperatures and are used for comparison. They do not mean that the medium and high temperatures are so high that they cannot be cooled by outdoor natural cold air.

[0193] In some embodiments, when the controller 105 starts the first heat dissipation mode, it opens and adjusts the air valves in the cold air inlet valve 302 and the hot air exhaust valve 202 to their maximum opening.

[0194] It can be understood that in some embodiments, the air quality is high in the first heat dissipation mode. At this time, the outdoor natural cold air can enter the data center computer room 100 for heat exchange. Therefore, the air valves in the cold air inlet valve 302 and the hot air exhaust valve 202 can be opened and adjusted to the maximum opening degree to facilitate the inflow of outdoor natural cold air and the outflow of hot air.

[0195] Furthermore, in some embodiments, when the controller 105 activates the first sub-mode, it closes all the air valves in the auxiliary cooling air valve module 403;

[0196] When the controller 105 starts the second sub-mode, it opens the first auxiliary cooling air valve 4031 and / or the second auxiliary cooling air valve 4032 in the auxiliary cooling air valve module 403, and closes the third auxiliary cooling air valve 4033 in the auxiliary cooling air valve module 403.

[0197] Among them, opening the first auxiliary cooling air valve 4031 simultaneously activates the spraying state of all spray chambers in the spray module 401;

[0198] In addition, the opening degree of the first auxiliary cooling air valve 4031 and / or the second auxiliary cooling air valve 4032 is controlled according to the air quality.

[0199] It can be understood that in some embodiments, in the first heat dissipation mode, when the outdoor temperature is low, the controller 105 starts the first sub-mode, at which time the outdoor natural cold air flows directly into the data center server room 100 through the natural cold air inlet channel 102 for heat dissipation, without the need to activate the auxiliary cooling module to dissipate the outdoor natural cold air, and the corresponding air valve does not need to be opened. In the first heat dissipation mode, when the outdoor temperature is high, the controller 105 activates the second sub-mode, which requires cooling the outdoor natural cold air. Specifically, since there is no need to exhaust the incoming outdoor natural cold air, only the second return air heat exchange chamber 4022 in the spray module 401 or return air heat exchange module 402 is needed. Therefore, the third auxiliary cooling air valve 4033 in the auxiliary cooling air valve module 403 is closed, and the entire heat dissipation process does not involve the use of the first return air heat exchange chamber 4021 for heat dissipation. At the same time, the first auxiliary cooling air valve 4031 and / or the second auxiliary cooling air valve 4032 in the auxiliary cooling air valve module 403 are opened, and all spray chambers in the spray module 401 are activated while the first auxiliary cooling air valve 4031 is opened. The spray mode ensures that the air flowing through all spray chambers is cooled by the spray, resulting in cooled air for heat dissipation inside the data center server room 100. It should be noted that when the outdoor temperature is high, the second auxiliary cooling air valve 4032 can be left unopened. This is because the air flowing out of the second auxiliary cooling air valve 4032 is cooled only by passing through the second return air heat exchange chamber 4022 before being sent into the mixing box 303. The air flowing out of the first auxiliary cooling air valve 4031 is also cooled by passing through the second return air heat exchange chamber 4022 before being sent to the second spray chamber 4012 for cooling. The cooling force is stronger and the cooling effect is better. Therefore, the first auxiliary cooling air valve 4031 is always open when the second sub-mode is activated.

[0200] In some embodiments, when the controller 105 starts the second heat dissipation mode, it opens the air valves in the cold air inlet valve, the hot air exhaust valve, and the third auxiliary cooling air valve 4033 in the auxiliary cooling air valve module 403 and adjusts the corresponding opening degree according to the air quality control, and starts the first return air heat exchange chamber 4021.

[0201] It can be understood that in some embodiments, the air quality in the second heat dissipation mode is moderate. Therefore, similar to the first heat dissipation mode, the air valves in the cold air inlet valve 302 and the hot air exhaust valve 202 are also opened, but they are not adjusted to the maximum opening. This is because the air quality at this time is not good enough (e.g., not low enough). The third auxiliary cooling valve 4033 in the auxiliary cooling valve module 403 is opened so that a portion of the outdoor natural cold air can be discharged through the third auxiliary cooling valve 4033 and the first return air heat exchange chamber 4021 in sequence. At the same time, the air flowing in the first return air heat exchange chamber 4021 can absorb a portion of the heat from the second return air heat exchange chamber 4022. Specifically, starting the first return air heat exchange chamber 4021 can be understood as starting the exhaust device corresponding to the first return air heat exchange chamber 4021, thereby providing the power for airflow.

[0202] Furthermore, in some embodiments, when the controller 105 activates the third sub-mode, it shuts off the spraying state of all spray chambers in the spray module 401, opens the second auxiliary cooling valve 4032 in the auxiliary cooling valve module 403, and closes the third auxiliary cooling valve 4033 in the auxiliary cooling valve module 403.

[0203] When the controller 105 starts the fourth sub-mode, it starts the spraying state of the first spray chamber 4011 in the spray module 401, stops the spraying state of the second spray chamber 4012 in the spray module 401, opens the second auxiliary cooling air valve 4032, and closes the third auxiliary cooling air valve 4033.

[0204] When the controller 105 starts the fifth sub-mode, it starts the spraying state of the first spray chamber 4011 and the second spray chamber 4012, opens the third auxiliary cooling air valve 4033, and closes the second auxiliary cooling air valve 4032.

[0205] In some embodiments, under the second heat dissipation mode, when the outdoor temperature is low, the controller 105 activates the third sub-mode. At this time, some outdoor natural cold air is discharged from the first return air heat exchange chamber 4021, and another portion of outdoor natural cold air directly enters the data center server room 100. Simultaneously, due to the reduction in the total intake of outdoor natural cold air, the second auxiliary cooling damper 4032 in the auxiliary cooling damper module 403 is opened, and the second return air heat exchange chamber 4022 is activated. This allows indoor air to undergo return air heat exchange in the second return air heat exchange chamber 4022 before flowing into the data center server room via the mixing box 303 and the blower 304, thus completing indoor return air heat exchange and ensuring that the heat inside the data center server room is effectively and promptly dissipated. When the outdoor temperature is moderate (neither high nor low, within a preset range), the controller 105 activates the fourth sub-mode. Similarly, at this time, some outdoor natural cold air is discharged from the first return air heat exchange chamber 4021, and another portion of outdoor natural cold air directly enters the data center server room, opening the auxiliary cooling damper module 403. Simultaneously with the activation of the second auxiliary cooling air valve 4032, the second return air heat exchange chamber 4022 is started. Since the outdoor temperature rises at this time, more auxiliary cooling functions need to be activated. Specifically, the spraying state of the first spray chamber 4011 in the spray module 401 is activated so that the outdoor fresh air is cooled by the spray chamber before entering the data center server room 100. When the outdoor temperature is high, the spraying state of the first spray chamber 4011 and the second spray chamber 4012 is activated, and the third auxiliary cooling air valve is turned on. Valve 4033 closes the second auxiliary cooling air valve 4032, so that the outdoor natural fresh air is sprayed and cooled by the spray room before entering the data center computer room 100. The indoor air passes through the second return air heat exchange chamber 4022 and the second spray chamber 4012 in sequence, and undergoes heat exchange treatment and spray cooling treatment respectively. At the same time, under the control of the controller 105, the opening of the cold air inlet valve can be appropriately reduced to reduce the total air intake of outdoor natural air, while ensuring the supply of oxygen by outdoor natural air so that the staff can work normally.

[0206] Furthermore, in some embodiments, after opening the air valve in the hot air exhaust valve, the controller 105 may further control the opening degree of the air valve in the hot air exhaust valve based on at least one air pressure sensor installed inside the data center computer room and at least one air pressure sensor installed outdoors.

[0207] In some embodiments, one or more air pressure sensors can be installed at one or more different locations inside the data center server room, and one or more air pressure sensors can also be installed at one or more different locations outside the data center system to monitor the indoor and outdoor air pressure values ​​in real time and obtain the indoor and outdoor air pressure difference. The controller 105 can adjust the opening of the air valve in the hot air exhaust valve according to the air pressure difference to maintain the positive pressure requirement inside the data center server room, thereby ensuring that the entire data center cooling system uses mechanical air supply and preventing outdoor natural wind with poor air quality from entering the data center server room.

[0208] In some embodiments, when the controller 105 activates the third heat dissipation mode, it closes the air valves in the cold air inlet valve 302 and the hot air exhaust valve 202.

[0209] It can be understood that in some embodiments, the air quality is poor in the third heat dissipation mode, outdoor natural air is not allowed to enter the data center computer room 100, and all the air valves in the cold air inlet valve 302 and the hot air exhaust valve 202 are closed.

[0210] In some embodiments, when the controller 105 activates the sixth sub-mode, it closes the first auxiliary cooling air valve 4031 in the auxiliary cooling air valve module 403, opens the second auxiliary cooling air valve 4032 and the third auxiliary cooling air valve 4033 in the auxiliary cooling air valve module 403 to the maximum opening, activates the spraying state of the first spray chamber 4011 in the spray module 401, and closes the spraying state of the second spray chamber 4012 in the spray module 401.

[0211] When the controller 105 activates the seventh sub-mode, it opens the first auxiliary cooling air valve 4031 to its maximum opening, closes the second auxiliary cooling air valve 4032 and the third auxiliary cooling air valve 4033, activates the spraying state of the second spray chamber 4012, and closes the spraying state of the first spray chamber 4011.

[0212] It can be understood that, in some embodiments, in the third heat dissipation mode, when the outdoor temperature is low, the spraying state of the first spray chamber 4011 in the spray module 401 is activated so that the outdoor natural air flows into the third auxiliary cooling air valve 4033 at the lowest possible temperature. The third auxiliary cooling air valve 4033 in the auxiliary cooling air valve module 403 is opened to its maximum opening so that the outdoor natural air flows from the third auxiliary cooling air valve 4033 into the first return air heat exchange chamber 4021, thereby absorbing the heat from the second return air heat exchange chamber 4022. The second auxiliary cooling air valve 4032 in the auxiliary cooling air valve module 403 is opened to its maximum opening so that the indoor air flows through the first return air heat exchange chamber 4021. After the return air heat exchanger 4022 exchanges heat, it flows back into the data center server room 100. When the outdoor temperature is high, the second auxiliary cooling air valve 4032 is closed to prevent outdoor air from entering the data center cooling system. The third auxiliary cooling air valve 4033 is closed, the first auxiliary cooling air valve 4031 is opened to its maximum opening, the second spray chamber 4012 is activated, and the first spray chamber 4011 is deactivated. This allows indoor air to be cooled by the second return air heat exchanger 4022 and the second spray chamber 4012 before re-entering the data center server room 100, thus achieving heat dissipation for the data center. In some typical embodiments, considering the large heat generation per unit time in the data center server room under poor air quality conditions, the number of heat exchange tubes in the second return air heat exchanger can be increased. Alternatively, to ensure normal oxygen supply, oxygen supply equipment can be installed inside the data center server room.

[0213] It should be noted that when deploying the data center cooling system as described in any of the foregoing embodiments in an actual data center, the data center cooling system can be built on different floors and / or in different computer rooms, and the number and / or location of the internal sub-components in the data center cooling system can be adjusted adaptively.

[0214] It should be noted that although the operations of the present invention have been described in a specific order in the above embodiments and accompanying drawings, this does not require or imply that these operations must be performed in that specific order, or that all the operations shown must be performed to achieve the desired result. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0215] Corresponding to the data center cooling system described above, some embodiments of this specification also provide a data center cooling method, see reference.

It can be understood that the data center can be a hub of one or more layers and storing a network of specific devices for transmitting, accelerating, displaying, computing and storing data information on the Internet network infrastructure. Equipping the computer rooms in the data center with the data center heat dissipation system described in any of the above embodiments when building the data center is beneficial to saving the power consumption cost of the data center and reducing carbon emissions.

[0223] Computer device 1102 may also include an input / output interface 1110 (I / O) for receiving various inputs (via input device 1112) and providing various outputs (via output device 1114). A specific output mechanism may include a presentation device 1116 and an associated graphical user interface 1118 (GUI). In other embodiments, the input / output interface 1110 (I / O), input device 1112, and output device 1114 may be omitted, and the device may function solely as a computer device within a network.
