Description

Technical Field

[0001] This application relates to the field of data center technology, and in particular to a data center air supply system and a data center computer room. Background Technology

[0002] With the rapid development of information technology, data centers, as the core carriers of information processing and storage, have become a key research focus in terms of energy efficiency and stability.

[0003] In related technologies, since the air conditioning equipment is located on one side of the data center server room, the cold air delivered by the air conditioning equipment enters the cold aisle next to the server rack from one side, or the cold air enters the space below the cold aisle from one side and then enters the cold aisle. In this way, in the area near the air outlet of the air conditioning equipment, the cold air is directly affected by the air supply force, resulting in a large wind speed, a high dynamic pressure value and a low static pressure value. According to fluid mechanics and heat dissipation and ventilation principles, the air intake effect of the server rack mainly depends on the external static pressure. Insufficient static pressure will make it difficult for the cold air to smoothly penetrate the ventilation holes of the server rack and enter the interior, and it will not be able to fully contact the heat-generating components of the server rack to complete heat exchange. This will easily cause heat accumulation inside the server rack in the near-end area, resulting in local hot spots in the data center server room. Summary of the Invention

[0004] The purpose of this application is to provide a data center air supply system and a data center computer room, which can solve the problem of local hot spots in data center computer rooms in related technologies.

[0005] In a first aspect, embodiments of this application provide a data center air supply system for heat dissipation of a rack group. The rack group includes at least two racks arranged along a first direction. The data center air supply system includes an air conditioning unit. The data center air supply system is provided with a side air intake channel, a bottom air intake channel, and a cold aisle. The cold aisle is disposed on a first side of the rack group and extends along the first direction. The side air intake channel is disposed on one side of the cold aisle in the first direction. The bottom air intake channel is disposed below the cold aisle, and both the side air intake channel and the bottom air intake channel are connected to the cold aisle. Both the side air intake channel and the bottom air intake channel are connected to the air outlet of the air conditioning unit.

[0006] Secondly, this application embodiment also provides a data center computer room, which includes a main computer room, a rack group installed in the main computer room, and the aforementioned data center air supply system. The rack group includes at least two racks arranged along a first direction. The air conditioning equipment of the data center air supply system is installed on one side of the main computer room. The bottom air intake channel of the data center air supply system is located below the main computer room. The side air intake channel and cold aisle of the data center air supply system are installed in the main computer room. The cold aisle is located on the first side of the rack group.

[0007] In this embodiment, the data center air supply system is provided with a side air intake channel and a bottom air intake channel. The side air intake channel is located on one side of the cold aisle in the first direction, and the bottom air intake channel is located below the cold aisle. Both the side air intake channel and the bottom air intake channel are connected to the air outlet of the air conditioning equipment and the cold aisle. In this way, the cold air delivered by the air conditioning equipment can be split into two paths to achieve zoned air supply. This can relatively reduce the wind speed of the two cold air streams and reduce the dynamic pressure of the cold air. As a result, when the two cold air streams flow through the racks in the near-end area, the dynamic pressure value of the cold air in the near-end area is reduced, which can effectively increase the static pressure value in the near-end area. This facilitates the entry of cold air into the racks in the near-end area, effectively cooling the racks in the near-end area and effectively eliminating local hot spots.

[0008] Furthermore, since some cold air enters the cold aisle from one side and the rest from below, the cold air preferentially enters areas of lower air pressure during the air conditioning system's operation. When some cold air enters from one side, the air pressure near the aisle increases due to this pressure difference. At this point, the cold air below the aisle, driven by the pressure difference, flows towards the lower-pressure areas further away, ensuring sufficient cold air supply to the server racks in those areas and helping to eliminate localized hotspots.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The data center air supply system and data center computer room provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0014] refer to Figures 1-9 The present application provides a data center air supply system that can be used to dissipate heat from a rack group 200. The rack group 200 may include at least two racks 201 arranged along a first direction a.

[0015] In some embodiments, a data center may include at least two sets of racks 200, which allows the data center to integrate more racks 201, enabling the data center to perform more functions.

[0016] Among them, such as Figures 1-6As shown, the data center air supply system may include an air conditioning unit 310. The data center air supply system may be provided with a side air intake duct 600, a bottom air intake duct 700, and a cold aisle 500. The cold aisle 500 may be used to set on the first side of the rack group 200 and may extend along the first direction a. The side air intake duct 600 may be set on one side of the cold aisle 500. Specifically, the side air intake duct 600 may be located on one side of the cold aisle 500 in the first direction a. The bottom air intake duct 700 may be set below the cold aisle 500. Both the side air intake duct 600 and the bottom air intake duct 700 are connected to the cold aisle 500. Both the side air intake duct 600 and the bottom air intake duct 700 are connected to the air outlet of the air conditioning unit 310. In this way, the cool air delivered by the air conditioning unit 310 can enter the cold aisle 500 through the side air inlet 600 and the bottom air inlet 700, and then enter the cabinet 201 of the cabinet group 200 from the cold aisle 500 to cool the cabinet 201. For example, in one embodiment, the bottom air inlet 700 can be located directly below the cold aisle 500, and vertically, the cold aisle 500 can cover the bottom air inlet 700. For instance, the length and width of the cold aisle 500 are the same as the length and width of the bottom air inlet 700, respectively. In another embodiment, vertically, the bottom air inlet 700 can cover all parts of the main computer room 100 described below, that is, the bottom air inlet 700 can cover all the hot aisles 900, all the cabinet groups 200, and all the cold aisles 500 described below. In another embodiment, a portion of the bottom air intake duct 700 may be located directly below the cold aisle 500, and in the vertical direction, the cold aisle 500 may cover a portion of the bottom air intake duct 700.

[0017] It should be noted that the cabinet 201 near the air outlet of the air conditioning equipment 310 is the cabinet 201 in the near-end area, and the cabinet 201 far from the air outlet of the air conditioning equipment 310 is the cabinet 201 in the far-end area.

[0018] In this embodiment, the data center air supply system is provided with a side air inlet channel 600 and a bottom air inlet channel 700. The side air inlet channel 600 is located on one side of the cold aisle 500, and the bottom air inlet channel 700 is located below the cold aisle 500. Both the side air inlet channel 600 and the bottom air inlet channel 700 are connected to the air outlet of the air conditioning equipment 310 and the cold aisle 500. In this way, the cold air delivered by the air conditioning equipment 310 can be split into two paths to achieve zoned air supply. This can relatively reduce the wind speed of the two cold air streams and reduce the dynamic pressure of the cold air. As a result, when the two cold air streams flow through the racks 201 in the near-end area, the dynamic pressure value of the cold air in the near-end area is reduced, which can effectively increase the static pressure value in the near-end area. This facilitates the entry of cold air into the racks 201 in the near-end area, which can effectively cool the racks 201 in the near-end area and effectively eliminate local hot spots.

[0019] Furthermore, since some cold air enters the cold aisle 500 from one side and another from below, during the air supply process of the air conditioning unit 310, the cold air preferentially enters the area with lower air pressure. When some cold air enters from one side of the cold aisle 500, the air pressure in the near-end area of ​​the cold aisle 500 increases due to the influence of this portion of cold air. At this time, the cold air below the cold aisle 500 is driven by the pressure difference to flow towards the far-end area of ​​the cold aisle 500 where the air pressure is even lower. This ensures that there is sufficient cold air supply at the cabinet 201 in the far-end area, which helps to eliminate local hot spots in the far-end area.

[0020] In this embodiment, the side and bottom air supply zones significantly optimize the unevenness of the conventional airflow organization in related technologies. By using zoned air supply, the data center air supply system can meet the cooling requirements of the rack 201 while ensuring that the cold airflow is evenly distributed to each high-power rack 201. This achieves a significant optimization of the airflow organization and reduces the occurrence of local hot spots in the main body 100 of the data center due to uneven airflow organization.

[0021] In optional embodiments, such as Figures 1-6 As shown, the data center air supply system may further include an air supply static pressure chamber 400. The air outlet of the air conditioning unit 310 can be connected to the side air inlet channel 600 and the bottom air inlet channel 700 through the air supply static pressure chamber 400. In this embodiment, the air supply static pressure chamber 400 can buffer the cold air. After the high-speed airflow delivered by the air conditioning unit 310 enters the air supply static pressure chamber 400, the flow velocity can be significantly reduced, and the dynamic pressure can be converted into static pressure. At the same time, the airflow is fully mixed and diffused in the air supply static pressure chamber 400. Furthermore, the air supply static pressure chamber 400 can act as a rectifier, which can change the directionality of the high-speed jet, so that the airflow flows to the side air inlet channel 600 and the bottom air inlet channel 700 in a stable state.

[0022] In other embodiments, the data center air supply system may also exclude the air supply static pressure chamber 400.

[0023] In this embodiment, the air conditioning equipment 310 can be connected to the air supply static pressure chamber 400 through the air supply duct 311.

[0024] In some embodiments, at least two air conditioning units 310 may be provided, and each air conditioning unit 310 can be connected to the supply air static pressure chamber 400. In this embodiment, the cold air from each air conditioning unit 310 simultaneously enters the supply air static pressure chamber 400, which can effectively offset the wind speed fluctuations and turbulence damage at the air outlet of a single air conditioning unit 310, allowing the cold air to mix fully in the supply air static pressure chamber 400 and form a stable and uniform air pressure field. Compared with the method of each air conditioning unit 310 directly supplying air to the side air intake channel 600 and / or the bottom air intake channel 700, this can ensure that the cold air pressure obtained by the side air intake channel 600 and the bottom air intake channel 700 is consistent, thereby making the wind speed and temperature field of the cold aisle 500 on the first side of each cabinet group 200 uniform. Furthermore, when some air conditioning units 310 are damaged, other air conditioning units 310 can still provide cold air to each cold aisle 500.

[0025] In this embodiment, at least two sets of cabinet groups 200 can be arranged at intervals along the second direction b, which can intersect with the first direction a. Specifically, the second direction b is perpendicular to the first direction a. For example, the second direction b can be the width direction of the main body 100 of the data center as described below, and the first direction a is the length direction of the main body 100 of the data center.

[0026] Optionally, the side air intake duct 600 can extend along the second direction b, and the cold aisles 500 of each rack group 200 arranged along the second direction b are all connected to the side air intake duct 600. With this configuration, the side air intake duct 600 can simultaneously deliver cold air with consistent pressure to the cold aisles 500 of each rack group 200. Furthermore, the side air intake duct 600 extending along the second direction b replaces multiple independent side air intake ducts 600, requiring only one main air duct to cover all rack groups 200 in the width direction. This significantly reduces the number of air ducts and the use of sealing components, thereby simplifying the structure of the data center air supply system and reducing construction costs.

[0027] In an optional embodiment, an air supply regulator (not shown in the figure) may be provided between the air supply static pressure chamber 400 and the side air inlet channel 600. The air supply regulator can adjust the communication area between the air supply static pressure chamber 400 and the side air inlet channel 600. This configuration allows direct control of the volume and velocity of the cold air flowing into the side air inlet channel 600. For example, when the dynamic pressure in the near-end area of ​​the cold aisle 500 is detected to be too high and the static pressure insufficient, the air supply regulator can be controlled to reduce the connection area between the air supply static pressure chamber 400 and the side air intake channel 600, thereby reducing the flow velocity of the side airflow and promoting the further conversion of airflow pressure into static pressure. This ensures that the cold air can smoothly pass through the cabinet 201 in the near-end area, preventing heat accumulation in the cabinet 201 in the near-end area due to poor air intake. Furthermore, when the cabinet 201 in the far-end area has a high load and requires more cooling compensation, the air supply regulator can be controlled to reduce the connection area between the air supply static pressure chamber 400 and the side air intake channel 600, causing more cold air in the air supply static pressure chamber 400 to flow to the bottom air intake channel 700. This leverages the pressure difference to enhance the airflow supply to the cabinet 201 in the far-end area, solving the problem of airflow attenuation in the cabinet 201 in the far-end area in traditional single-sided air supply methods, and effectively improving the cooling effect on the cabinet 201 in the far-end area.

[0028] In other embodiments, an air supply regulating component may not be provided between the air supply static pressure chamber 400 and the side air inlet channel 600.

[0029] Optionally, a vent can be provided on the side wall of the air supply static pressure chamber 400 facing the side air inlet channel 600. The air supply static pressure chamber 400 can be connected to the side air inlet channel 600 through the vent. An air supply adjustment component can be provided at the vent and can adjust the conduction area of ​​the vent to adjust the connection area between the air supply static pressure chamber 400 and the side air inlet channel 600.

[0030] In some embodiments, the air supply regulating component can be a first louver, and by adjusting the angle of the first louver's blades, the conduction area of ​​the vent can be changed. Of course, the air supply regulating component can be any other structure capable of closing and opening the vent.

[0031] In one embodiment, multiple ventilation openings can be provided on the side wall of the air supply static pressure chamber 400 facing the side air intake channel 600. Each ventilation opening can be respectively set to correspond one-to-one with the cold aisle 500 on the first side of each rack group 200 arranged along the second direction b. In this way, the cold air discharged from each ventilation opening can enter each cold aisle 500 respectively, and can avoid the cold air from directly colliding with the side wall of the rack 201, the enclosure structure 910 of the hot aisle 900 (described below) and other structures that would cause turbulence, etc., ensuring that the cold air enters the cold aisle 500 in a stable state, which can effectively improve the utilization rate of the cold air.

[0032] In another approach, the side wall of the air supply static pressure chamber 400 facing the side air intake channel 600 may also be provided with only one ventilation opening, which can cover the cold aisle 500 on the first side of each cabinet group 200.

[0033] In an optional embodiment, a partition 800 can be provided between the bottom air intake channel 700 and the cold aisle 500. The partition 800 can have multiple air outlets 810, and the bottom air intake channel 700 and the cold aisle 500 can be connected through the air outlets 810. This configuration creates a physical barrier between the bottom air intake channel 700 and the cold aisle 500, ensuring that cold air can only enter the cold aisle 500 through the pre-set air outlets 810, effectively improving the utilization rate of cold air. Furthermore, compared to a direct connection between the bottom air intake channel 700 and the cold aisle 500, connecting the bottom air intake channel 700 through the air outlets 810 effectively prevents most of the cold air from directly entering the near-end area of ​​the cold aisle 500 from below, thus reducing the cooling effect on the cabinets 201 in the far-end area. In addition, the partition 800 can also serve as flooring within the main computer room 100, allowing operators to walk within the main computer room 100.

[0034] In other embodiments, the partition 800 may not be provided between the bottom air inlet channel 700 and the cold aisle 500, and the bottom air inlet channel 700 may be directly connected to the cold aisle 500.

[0035] In one alternative embodiment, in one approach, the partition 800 vertically covers the cold aisle 500, and the air outlets 810 can be evenly distributed along a first direction a, so that the partition 800 is fully covered with air outlets 810. This arrangement allows cold air from the bottom air inlet channel 700 to enter any area of ​​the cold aisle 500, and simplifies the structure of the partition 800, making it easier to manufacture. In another approach, the partition 800 vertically covers the cold aisle 500, the air outlets 810 can be arranged along the first direction a, and the density of the air outlets 810 can gradually increase along the direction from the side air inlet channel 600 to the cold aisle 500. With this configuration, since the air conditioning unit 310 is located on the side of the side air intake duct 600 away from the cold aisle 500, the cold air delivered by the air conditioning unit 310 will enter the bottom air intake duct 700 from the side of the side air intake duct 600. That is, the cold air will flow from the near end area to the far end area in the bottom air intake duct 700. To ensure that the cabinet 201 in the far end area receives sufficient cold air supply, the density of the air outlets 810 gradually increases from the side air intake duct 600 to the cold aisle 500. This results in more air outlets 810 in the far end area of ​​the cold aisle 500, increasing the bottom air intake volume and thus compensating for the reduced cooling capacity due to transmission losses in the far end. Furthermore, the density of the air outlets 810 in the near end area of ​​the cold aisle 500 is relatively low, which avoids airflow collisions between the bottom and side air intakes in the near end area, preventing local vortices that could interfere with the entry of cold air into the cabinet 201.

[0036] In another optional embodiment, the partition 800 may include a first partition and a second partition, the first partition being connected to the second partition. The first partition may be located on the side of the second partition near the side air inlet channel 600, and the air outlet 810 may be provided on the second partition. In this embodiment, the first partition does not have an air outlet 810, allowing the first partition to separate the near-end region of the cold aisle 500 from the near-end region of the bottom air inlet channel 700, thus acting as an airflow barrier in the near-end region. This prevents the airflow from the bottom air inlet from directly entering the cold aisle 500 in the near-end region, avoiding a collision with the airflow from the side air inlet channel 600 in the near-end region and reducing the generation of local eddies. Furthermore, the first partition can guide the bottom airflow, causing it to flow towards the far-end region. The second partition is provided with an air outlet 810, allowing the bottom airflow to enter the far-end region of the cold aisle 500 through the air outlet 810, making the path of the bottom airflow more in line with the design concept of less near-end compensation and more far-end compensation, thereby enhancing the accuracy of far-end airflow compensation.

[0037] Optionally, the partition 800 can be an anti-static structure. This design can eliminate equipment damage, data failures and safety hazards caused by the accumulation and release of static electricity, and ensure the stable operation of the server rack 201 in the data center and the safety of personnel.

[0038] In this embodiment, by adjusting the air supply regulating component and changing the number, size, and distribution of the air supply holes 810, the proportion of air supply volume in the side air inlet channel 600 and the bottom air inlet channel 700 can be adjusted to reduce the air supply difference between the cabinet 201 in the near-end area and the cabinet 201 in the far-end area. Here, no specific limitations are made on the number, size, and distribution of the air supply regulating component and the air supply holes 810; these can be set according to actual needs.

[0039] In an optional embodiment, at least two air conditioning devices 310 may be provided, including a first air conditioning device 3101 and a second air conditioning device 3102, such as... Figure 4 and Figure 6 As shown, the first air conditioning unit 3101 and the second air conditioning unit 3102 can be located on both sides of the bottom air intake channel 700 in the first direction a, respectively. Furthermore, the air outlets of both the first and second air conditioning units 3101 are connected to the bottom air intake channel 700. This configuration forms a symmetrical double-sided air supply structure. The cool air output by the first and second air conditioning units 3101 diffuses from both ends of the bottom air intake channel 700 towards the middle area, effectively avoiding the problem of "large air volume at the near end and reduced air volume at the far end" caused by single-sided air supply in related technologies. This effectively improves the cooling effect on the cabinet 201. Moreover, when one side of the air conditioning unit 310 malfunctions and stops, the other side can operate independently, continuously supplying cool air to the bottom air intake channel 700, ensuring uninterrupted heat dissipation for the cabinet 201.

[0040] At least two side air intake channels 600 are provided, including a first side air intake channel 610 and a second side air intake channel 620. The first side air intake channel 610 is connected to the air outlet of the first air conditioning unit 3101, and the second side air intake channel 620 is connected to the air outlet of the second air conditioning unit 3102. Both the first and second side air intake channels 610 and 620 are connected to the cold aisle 500. In this embodiment, the first side air intake channel 610 and the first air conditioning unit 3101, and the second side air intake channel 620 and the second air conditioning unit 3102, respectively form independent air supply branches. Both side air intake channels 600 are connected to the cold aisle 500, allowing cold air to be simultaneously supplied from both sides of the cold aisle 500. This allows the cold air output from the first and second air conditioning units 3101 and 3102 to diffuse from the two side air intake channels 600 towards the central area, thereby effectively improving the heat dissipation efficiency of the cabinet 201.

[0041] In other embodiments, there may be only one air conditioning unit 310 and only one side air intake duct 600.

[0042] In optional embodiments, such as Figure 1 and Figure 3 As shown, the data center air supply system can also be equipped with a hot aisle 900. The hot aisle 900 can be installed on the second side of the rack group 200, which is opposite to the first side. The hot aisle 900 can be connected to the cold aisle 500 through the internal channel of the rack 201, so that cold air can enter the hot aisle 900 from the cold aisle 500 through the internal channel of the rack 201, so that the cold air can absorb the heat in the rack 201 and exhaust the heat in the rack 201 through the hot aisle 900.

[0043] like Figure 2 and Figure 4 As shown, the data center air supply system can also be equipped with a return air chamber 1000. The return air chamber 1000 can be located above and connected to the hot aisle 900, and can also be connected to the return air vent of the air conditioning unit 310. In this embodiment, the return air chamber 1000 can collect the high-temperature hot air exhausted from the hot aisle 900, and the hot air inside the return air chamber 1000 can be discharged through the return air vent of the air conditioning unit 310, making it easy to exhaust the hot air. Furthermore, since the return air chamber 1000 is integrated above the hot aisle 900, there is no need to arrange complex return air ducts in the data center computer room, which helps to simplify the structure of the computer room and reduce construction difficulty and cost.

[0044] In other embodiments, the data center air supply system may also exclude the return air chamber 1000, and the hot aisle 900 may be directly connected to the external environment.

[0045] In some embodiments, the cold aisles 500 of each cabinet group 200 are connected, and an enclosure structure 910 is provided at the hot aisle 900 of each cabinet group 200. The enclosure structure 910 separates the hot aisle 900 from the cold aisle 500 to prevent hot air in the hot aisle 900 from entering the cold aisle 500.

[0046] Optionally, a hot return air ceiling 1010 is provided between the return air chamber 1000 and the cold aisle 500. The hot return air ceiling 1010 can separate the return air chamber 1000 from the cold aisle 500 to prevent hot air from entering the cold aisle 500.

[0047] In an optional embodiment, the data center air supply system may further include an air conditioning room 300, within which a platform 3002 is provided. Air conditioning equipment 310 may be mounted on the platform 3002. An air inlet may be provided on the first side wall of the air conditioning room 300, and an air inlet regulating component 3001 may be provided at the air inlet. The air inlet regulating component 3001 can be used to adjust the ventilation area of ​​the air inlet. In this embodiment, the air conditioning equipment 310 is centrally located in the air conditioning room 300, spatially separated from the main computer room 100 described below. This facilitates maintenance and repair of the air conditioning by operation and maintenance personnel, avoids interference with the server racks 201 during operation, and effectively isolates the noise and vibration generated by the air conditioning equipment 310 during operation, preventing interference with the operation of the server racks 201 within the main computer room 100. Furthermore, the air inlet regulating component 3001, in conjunction with the enclosed design of the air conditioning room 300, enables precise control of the air intake in the air conditioning room 300. By adjusting the ventilation area, the fresh air volume can be effectively controlled, improving the working efficiency of the air conditioning equipment 310.

[0048] Optionally, the air inlet regulating component 3001 can be a second louver, and the ventilation area of ​​the air inlet can be adjusted by adjusting the angle of the blades of the second louver.

[0049] In one embodiment, the air conditioning unit 310 may include a first cold source device, which may be located near the air supply static pressure chamber 400, or the first cold source device may be deployed directly near the cabinet 201 that needs to be cooled. This arrangement minimizes the path of cold air from its generation to its intake by the cabinet 201.

[0050] In this embodiment, the first cold source device can be used as a near-end cold source. After the cold air comes out of the air outlet of the near-end cold source, it only needs to travel a very short distance to reach the air supply static pressure chamber 400.

[0051] For example, the air outlet of the first cold source device can be connected to the air supply static pressure chamber 400 through the air supply duct 311 to provide cold air to the air supply static pressure chamber 400, and the return air outlet of the first cold source device can be connected to the return air chamber 1000 through the return air duct 312 to draw in hot return air from the return air chamber 1000. In this embodiment, the airflow path can be: first cold source device → air supply duct 311 → air supply static pressure chamber 400 → side air inlet duct 600 and bottom air inlet duct 700 → cold aisle 500 → cabinet 201 → hot aisle 900 → return air chamber 1000 → return air duct 312 → first cold source device.

[0052] Optionally, the first cold source equipment can be an indirect evaporative cooling unit or an integrated fluorine pump unit, etc.

[0053] In this embodiment, the air outlet of the first cold source device can be connected to the air supply static pressure chamber 400 through an air supply duct, and the cavity of the air supply duct can serve as an air supply channel 311. The return air outlet of the first cold source device can be connected to the return air chamber 1000 through a return air duct, and the cavity of the return air duct can serve as a return air channel 312.

[0054] In another embodiment, the air conditioning equipment 310 may include a second cold source device and an air conditioning unit. The air conditioning unit may be located near the supply air static pressure chamber 400. The air outlet of the air conditioning unit can be connected to the supply air static pressure chamber 400 through the supply air duct 311, and the return air outlet of the air conditioning unit can be connected to the return air chamber 1000 through the return air duct 312. The second cold source device is connected to the air conditioning unit through a cooling pipe to provide refrigerant to the air conditioning unit. Here, the refrigerant may include cooling water, cold air, etc. For example, the second cold source device can be connected to the water inlet of the air conditioning unit through a water supply pipe, and the second cold source device can be connected to the water outlet of the air conditioning unit through a return water pipe. The cooling pipe can provide a cold source for the air conditioning unit.

[0055] Here, the second cold source equipment can be used as a remote cold source. The remote cold source can be located in an area far away from cabinet 201, such as outside the computer room, and chilled water and other refrigerants can be transported to the air conditioning unit through cooling pipes.

[0056] In this embodiment, the airflow path can be: air conditioning unit → supply air duct 311 → supply air static pressure chamber 400 → side air inlet duct 600 and bottom air inlet duct 700 → cold aisle 500 → cabinet 201 → hot aisle 900 → return air chamber 1000 → return air duct 312 → air conditioning unit. The refrigerant flow path is: second cold source equipment → water supply pipe → water inlet of air conditioning unit → water outlet of air conditioning unit → return water pipe → second cold source equipment. Chilled water exchanges heat with the airflow in the air conditioning unit so that the air conditioning unit can provide cold air.

[0057] In this embodiment, the air conditioning unit 310 can be a dedicated air conditioner for the computer room or a wall-mounted air conditioner, etc. A partition wall is provided between the main computer room 100 and the air conditioning room 300, as described below. A partition wall is installed inside the main computer room 100, connecting the partition wall and forming a supply air static pressure chamber 400. Here, the partition wall can be provided with air outlets and return air vents. The air outlets connect the air outlet of the air conditioning unit 310 to the supply air static pressure chamber 400, and the return air vents connect the return air vent of the air conditioning unit to the return air chamber 1000. The air outlets can serve as supply air channels 311, and the return air vents can serve as return air channels 312.

[0058] In this embodiment, the method of supplying air to the cold aisle 500 through the side air inlet channel 600 and the bottom air inlet channel 700 can be understood as far-end air supply compared to the form of near-end air supply to the cabinet 201 to achieve heat dissipation through in-row air conditioners, back panel air conditioners, or near-end air walls. Its advantage is that the air conditioning equipment 310 and the cabinet 201 can be physically isolated in the computer room, avoiding the potential hazards caused by the condensate of the air conditioning equipment 310 and the water system corresponding to the in-row air conditioner, back panel air conditioner, or near-end air wall being too close to the physical space of the cabinet 201. In addition, by providing cool air through the air conditioning equipment 310 including the near-end cold source, the near-end cold source can be set close to the main body of the computer room 100. This avoids the problem of low energy efficiency caused by the air conditioning equipment 310 having to overcome pipe resistance due to long-distance refrigerant transportation. Furthermore, under the trend of high-power cabinets 201, the air conditioning equipment 310 including the near-end cold source can be adapted to optimize the airflow organization of the computer room by zoned air supply, making up for the disadvantage of far-end air supply in terms of airflow organization in the computer room compared to near-end air supply.

[0059] It should be noted that the specific structure of the air conditioning equipment 310 is not limited in this embodiment; it is only required that it can achieve the effect of cooling the cabinet 201.

[0060] Based on the data center air supply system provided in the embodiments of this application, the embodiments of this application also provide a data center computer room. The data center computer room may include a computer room main body 100, a rack group 200 disposed in the computer room main body 100, and the data center air supply system described in any of the above embodiments. The air conditioning equipment 310 of the data center air supply system is disposed on one side of the computer room main body 100. The bottom air inlet channel 700 of the data center air supply system is located below the computer room main body 100. The side air inlet channel 600 and the cold aisle 500 of the data center air supply system are disposed in the computer room main body 100. The cold aisle 500 is located on the first side of the rack group 200.

[0061] The beneficial effects achieved by the data center provided in this application embodiment are consistent with those achieved in the other application embodiment, and will not be repeated here.

[0062] In an optional embodiment, the rack group 200 is provided with at least two groups, which may include a first rack group 210 and a second rack group 220. The first rack group 210 and the second rack group 220 may be distributed at intervals along a first direction a. A connecting channel 1100 is formed between the first rack group 210 and the second rack group 220. The connecting channel 1100 is connected to the cold aisle 500 on the first side of the first rack group 210 and the cold aisle 500 on the first side of the second rack group 220, respectively.

[0063] In some embodiments, the first rack group 210 and the second rack group 220 are distributed at intervals along the first direction a, which can effectively utilize the space of the main body of the computer room 100 in the first direction a, and is conducive to arranging more racks 201. In addition, the connecting channel 1100 can directly connect the cold aisles 500 on the first side of the first rack group 210 and the second rack group 220, breaking the independent airflow boundary of the cold aisle 500 of a single rack group 200. When the cold air volume in the cold aisle 500 on the first side of a certain rack group 200 is insufficient, the connecting channel 1100 can guide the excess cold air in the cold aisle 500 on the first side of other rack groups 200 to supplement it, so that the wind speed and temperature field in the cold aisle 500 of each rack group 200 are kept balanced, thereby further reducing the possibility of overheating failure of local racks 201 due to insufficient cooling.

[0064] In this embodiment, the bottom air intake channel 700 can be connected to the cold aisle 500 on the first side of the first cabinet group 210 and the cold aisle 500 on the first side of the second cabinet group 220, respectively.

[0065] In other embodiments, the connection channel 1100 may not be provided between the first cabinet group 210 and the second cabinet group 220.

[0066] Optionally, the air conditioning equipment 310 may include a first air conditioning equipment 3101 and a second air conditioning equipment 3102. The first air conditioning equipment 3101 and the second air conditioning equipment 3102 may be respectively arranged on both sides of the main body of the computer room 100 in the first direction a. A first air supply static pressure chamber 410 may be arranged between the first air conditioning equipment 3101 and the main body of the computer room 100, and a second air supply static pressure chamber 420 may be arranged between the second air conditioning equipment 3102 and the main body of the computer room 100. The first air supply static pressure chamber 410 is connected to the air outlet of the first air conditioning equipment 3101, and the second air supply static pressure chamber 420 is connected to the air outlet of the second air conditioning equipment 3102. The data center air supply system is equipped with two side air intake channels 600, namely a first side air intake channel 610 and a second side air intake channel 620. The first side air intake channel 610 is located between the first air supply static pressure chamber 410 and the cold aisle 500 on the first side of the first rack group 210, and the first side air intake channel 610 is connected to both the first air supply static pressure chamber 410 and the cold aisle 500 on the first side of the first rack group 210. The second side air intake channel 620 is located between the second air supply static pressure chamber 420 and the cold aisle 500 on the first side of the second rack group 220, and the second side air intake channel 620 is connected to both the second air supply static pressure chamber 420 and the cold aisle 500 on the first side of the second rack group 220.

[0067] The bottom air inlet channel 700 can be connected to the first air supply static pressure chamber 410 and the second air supply static pressure chamber 420 on both sides of the first direction a, so that the cold air output by the first air conditioning equipment 3101 and the cold air output by the second air conditioning equipment 3102 can enter the bottom air inlet channel 700 from both sides of the bottom air inlet channel 700 on the first direction a.

[0068] In an optional embodiment, a cooling device (not shown in the figure) may be installed inside the cabinet 201 to cool down the cabinet 201. This arrangement can further reduce the temperature of the cabinet 201 to ensure stable operation of the cabinet 201.

[0069] Of course, cooling devices may not be installed inside rack 201.

[0070] Optionally, the cooling device can be a liquid cooling device, such as a liquid cooling plate. Of course, the cooling device can also be other devices, such as a fan or a thermoelectric cooling plate.

[0071] In one embodiment of this application, the data center server room may include a main server room 100 and a data center ventilation system, such as... Figure 1 , Figure 2 and Figure 5 As shown, the data center air supply system may include an air-conditioning room 300 and multiple air-conditioning devices 310 located within the air-conditioning room 300. The multiple air-conditioning devices 310 may be distributed at intervals along the second direction b. The air-conditioning room 300 may be located on one side of the main computer room 100 in the first direction a, and a static pressure chamber 400 is provided between the air-conditioning room 300 and the main computer room 100. The data center computer room may include multiple sets of server racks 200, and each set of server racks 200 may be arranged at intervals along the second direction b. The side air intake duct 600 and the bottom air intake duct 700 of the data center air supply system are both located within the main computer room 100. The side air intake duct 600 may extend along the second direction b and connect with the cold aisle 500 on the first side of each set of server racks 200. The bottom air intake duct 700 is located below the set of server racks 200 and is separated by a partition 800. The bottom air intake duct 700 connects with each cold aisle 500 through air supply holes 810 on the partition 800. The cold aisle 500 is connected to the hot aisle 900 on the second side of the cabinet group 200 through the internal passage of the cabinet 201. A return air chamber 1000 connected to the hot aisle 900 is set on the top of the main body of the computer room 100. The return air chamber 1000 is separated from the cold aisle 500 through the hot return air ceiling 1010. The return air chamber 1000 is connected to the air conditioning equipment 310 through the return air duct 312.

[0072] When the air conditioning unit 310 is turned on, the airflow is processed by the air conditioning unit 310 to form low-temperature air, i.e., cold air. Figure 5As shown, the air conditioning unit 310 delivers cold air into the air supply static pressure chamber 400 through the air supply duct 311, and then flows from the air supply static pressure chamber 400 into the side air inlet duct 600 and the bottom air inlet duct 700 respectively. The cold air in the side air inlet duct 600 enters the cold aisle 500 from one side, and the cold air in the bottom air inlet duct 700 enters the cold aisle 500 from below. The cold air in the cold aisle 500 enters the internal channel of the cabinet 201, where it absorbs heat from the cabinet 201 and forms high-temperature gas. The high-temperature gas enters the hot aisle 900, then enters the return air chamber 1000, and finally enters the air conditioning unit 310 through the return air duct 312. It is then cooled and cooled by the air conditioning unit 310 into low-temperature gas. This cycle repeats to dissipate heat from the cabinet 201.

[0073] In another embodiment of this application, the data center may include a main computer room 100 and a data center air supply system, such as Figure 3 , Figure 4 and Figure 6As shown, the data center air supply system may include a first air conditioning room 301, a second air conditioning room 302, a plurality of first air conditioning units 3101 located in the first air conditioning room 301, and a second air conditioning unit 3102 located in the second air conditioning room 302. The first air conditioning units 3101 and the second air conditioning units 3102 may be arranged at intervals along the second direction b. The first air conditioning room 301 and the second air conditioning room 302 may be located on both sides of the main body of the computer room 100 in the first direction a. A first air supply static pressure chamber 410 is provided between the first air conditioning room 301 and the main body of the computer room 100, and a second air supply static pressure chamber 420 is provided between the second air conditioning room 302 and the main body of the computer room 100. The data center air supply system may also be equipped with a first side air intake duct 610, a second side air intake duct 620, and a bottom air intake duct 700. The first side air intake duct 610, the second side air intake duct 620, and the bottom air intake duct 700 are all located within the main body 100 of the computer room. The first side air intake duct 610 can be connected to the first air supply static pressure chamber 410, the second side air intake duct 620 can be connected to the second air supply static pressure chamber 420, and both the first air supply static pressure chamber 410 and the second air supply static pressure chamber 420 are connected to the bottom air intake duct 700. The data center may also include multiple first rack groups 210 and multiple second rack groups 220. The first rack groups 210 and second rack groups 220 can be arranged at intervals along a first direction a, forming a connecting channel 1100 between them. Each first rack group 210 can be distributed at intervals along a second direction b, and each second rack group 220 can be distributed at intervals along a second direction b. Furthermore, the cold aisle 500 on the first side of each first rack group 210 is... The cold aisle 500 on the first side of each second cabinet group 220 is connected to the first side air intake 620. The bottom air intake 700 can be set at the bottom of the main body 100 of the computer room and is separated from the cold aisle 500 on the first side of the first cabinet group 210 and the cold aisle 500 on the first side of the second cabinet group 220 by the partition 800. The bottom air intake 700 is connected to each cold aisle 500 through the air intake holes on the partition 800. The cold aisle 500 is connected to the hot aisle 900 on the second side of the cabinet group 200 through the internal passage of the cabinet 201. A return air chamber 1000 connected to the hot aisle 900 is set on the top of the main body of the computer room 100. The return air chamber 1000 is separated from the cold aisle 500 by the hot return air ceiling 1010. The return air chamber 1000 can be connected to the first air conditioning unit 3101 and the second air conditioning unit 3102 through the first return air passage 3121 and the second return air passage 3122 respectively.

[0074] When the first air conditioning unit 3101 is turned on, the airflow is processed by the first air conditioning unit 3101 to form low-temperature air, i.e., cold air, such as... Figure 6As shown, the first air conditioning unit 3101 delivers cold air into the first air supply static pressure chamber 410 through the first air supply duct 3111, and then flows from the first air supply static pressure chamber 410 into the first side air inlet duct 610 and the bottom air inlet duct 700 respectively. The cold air in the first side air inlet duct 610 enters the cold aisle 500 on the first side of the first cabinet group 210 from one side of the cold aisle 500, and the cold air in the bottom air inlet duct 700 enters the cold aisle 500 on the first side of the first cabinet group 210 from below. The cold air in the cold aisle 500 on the first side of the cabinet group 210 enters the internal channel of the cabinet 201 of the first cabinet group 210. In the internal channel, it absorbs the heat of the cabinet 201 and forms high-temperature gas through heat exchange. The high-temperature gas enters the hot aisle 900 on the second side of the first cabinet group 210, then enters the return air chamber 1000, and finally enters the first air conditioning equipment 3101 through the first return air channel 3121. It is cooled and heat-exchanged by the first air conditioning equipment 3101 and becomes low-temperature gas. The cycle repeats to achieve heat dissipation for the first cabinet group 210.

[0075] When the second air conditioning unit 3102 is turned on, the airflow is processed by the second air conditioning unit 3102 to form low-temperature air, i.e., cold air, such as... Figure 6 As shown, the second air conditioning unit 3102 delivers cold air into the second air supply static pressure chamber 420 through the second air supply duct 3112, and then flows from the second air supply static pressure chamber 420 into the second side air inlet duct 620 and the bottom air inlet duct 700 respectively. The cold air in the second side air inlet duct 620 enters the cold aisle 500 on the first side of the second cabinet group 220 from one side of the cold aisle 500, and the cold air in the bottom air inlet duct 700 enters the cold aisle 500 on the first side of the second cabinet group 220 from below. The cold air in the cold aisle 500 on the first side of the cabinet group 220 enters the internal channel of the cabinet 201 of the second cabinet group 220. In the internal channel, it absorbs the heat of the cabinet 201 and forms high-temperature gas through heat exchange. The high-temperature gas enters the hot aisle 900 on the second side of the second cabinet group 220, then enters the return air chamber 1000, and finally enters the second air conditioning equipment 3102 through the second return air duct 3122. It is cooled and heat-exchanged by the second air conditioning equipment 3102 and becomes low-temperature gas. This cycle repeats to achieve heat dissipation for the second cabinet group 220.

[0076] This application embodiment is applicable to data center computer rooms where the near-end cold source air conditioning equipment 310 adopts side air supply. By adding the bottom air intake channel 700, zoned air supply is achieved, which reduces the problem of high air velocity in the near-end cabinet 201 of the air supply outlet and greatly optimizes the problem of uneven airflow organization that is common in side air supply methods.

[0077] This application embodiment is applicable to data center computer rooms where the near-end cold source air conditioning equipment 310 adopts underfloor air supply. By adding a side air intake channel 600, zoned air supply is achieved, which increases the air volume of the cabinets 201 in the near-end area. This makes up for the problem of insufficient air volume of the cabinets 201 in the near-end area due to the high flow velocity under the floor, and greatly optimizes the problem of uneven airflow organization that is common in underfloor air supply methods.

[0078] This application addresses the challenge of increasing power in server racks 201 within data center server rooms year by year. By implementing zoned air supply, it ensures that the air conditioning equipment 310 can meet the cooling requirements of the server racks 201 while also ensuring that the airflow is evenly distributed to each high-power server rack 201. This significantly optimizes the airflow organization and reduces hotspots in data center server rooms caused by uneven airflow.

[0079] This application adopts a zoned air supply system, which can optimize the layout of different computer room main bodies 100, the layout of server racks 201, the power of server racks 201, the layout of air conditioning equipment 310, and the performance of air conditioning equipment 310 by adjusting the perforation rate of air supply adjustment components and partitions 800, adjusting the position and height of air vents, adjusting the height of partitions 800 and the planar position of air supply holes 810 on partitions 800 within the cold aisle 500, and matching and optimizing better airflow organization.

[0080] This application can achieve better airflow distribution in the same computer room environment, improving the cooling safety of the computer room operation. It creates favorable conditions for increasing the supply air temperature of the air conditioning equipment 310, and increasing the supply air temperature can significantly reduce the operating energy consumption of the air conditioning equipment 310.

[0081] This application, under the same civil engineering conditions for the main body 100 of the data center, creates favorable conditions for the layout of the server racks 201 within the main body 100 with a compressed cold aisle width of 500 through zoned air supply, which can significantly increase the installed capacity of the main body 100 of the data center. Furthermore, it creates favorable conditions for continuously increasing the power density of the server racks 201.

[0082] In this application, the cold air delivered by the air conditioning equipment 310 through the air supply duct 311 can be divided into two streams through the side air inlet duct 600 and the bottom air inlet duct 700. The two streams of cold air enter the cold aisle 500 from the side air inlet duct 600 and the bottom air inlet duct 700 respectively, and then enter the internal channel of the cabinet 201 from the cold aisle 500. After absorbing the heat of the cabinet 201, they enter the return air chamber 1000 from the hot aisle 900, and then enter the return air duct 312 of the air conditioning equipment 310 from the return air chamber 1000.

[0083] like Figure 7 This refers to the method of heat dissipation for cabinet 201 through single-sided side air supply in related technologies, such as... Figure 7 As shown, the temperature of cabinet 201 in the near-end area is higher than that of cabinet 201 in the far-end area and cabinet 201 in the middle area. Therefore, it can be seen that there is a local hot spot in cabinet 201 in the near-end area.

[0084] In this application, as Figure 8 As shown, the cold air output by the air conditioning unit 310 enters the cold aisle 500 through the side air inlet channel 600 and the bottom air inlet channel 700, realizing the side and bottom zoned air supply. The temperature difference between the cabinet 201 in the near area and the cabinet 201 in the far area is small, which can effectively eliminate the phenomenon of local hot spots.

[0085] Furthermore, since the arrangement of the air conditioning units 310 in the side-supply airflow system corresponds to the position of the cold aisle 500, if one of the air conditioning units 310 malfunctions and requires maintenance, the intake air temperature of the cold aisle 500 corresponding to that malfunctioning unit may be directly affected. This could severely impact the intake air temperature of the rack 201, easily triggering a high-temperature alarm and server malfunction. Assuming the leftmost air conditioning unit 310 is the one requiring maintenance, shutting it down will negatively affect the rack 201 corresponding to and adjacent to it, resulting in poor heat dissipation. The temperature of the rack 201 closest to the leftmost air conditioning unit 310 may generally be higher than that of the rack 201 on the right. It should be noted that in this embodiment, apart from the malfunction and shutdown of some air conditioning units 310, other scenarios and conditions for each rack 201 can remain unchanged.

[0086] In this application, since each air conditioning unit 310 is connected to the supply air static pressure chamber 400, and both the side air inlet duct 600 and the bottom air inlet duct 700 are connected to the supply air static pressure chamber 400, the supply air static pressure chamber 400 can evenly distribute the cold air. Therefore, when one air conditioning unit 310 malfunctions and is under maintenance, it will not significantly affect the corresponding cabinet group 200. For example, when the rightmost air conditioning unit 310 is turned off, the temperature of the cabinet group 200 opposite to the rightmost air conditioning unit 310 is not significantly different from the temperatures of the other cabinet groups 200. Figure 9 As shown, when all air conditioning units 310 are turned on, the temperature difference between each cabinet 201 is relatively small.

[0087] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
