Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and more specifically, to a heat dissipation system for a data center. Background Technology

[0002] A data center is a complex facility comprising numerous servers, storage systems, network equipment, and other related infrastructure. It stores, processes, and distributes massive amounts of data, providing essential backend support for cloud computing, internet services, and business operations. Because the equipment in a data center generates significant heat during operation, its cooling system is a critical component in ensuring stable operation.

[0003] In existing technologies, the hot and cold aisles of data center cooling systems are not separated. As a result, during the cooling process, cold and hot air mix, requiring the cooling system to consume more energy to recool the air. This increases energy consumption and reduces the cooling efficiency of the system. Utility Model Content

[0004] The main objective of this invention is to provide a heat dissipation system for data centers to solve the problem of poor heat dissipation performance in existing data center heat dissipation systems.

[0005] To achieve the above objectives, this utility model provides a heat dissipation system for a data center. The heat dissipation system includes at least one heat dissipation unit, which comprises: a container having a first end and a second end arranged opposite each other along a first direction; the container having a cold aisle, an installation aisle, and a hot aisle arranged sequentially and connected along a second direction, all extending from the first end to the second end; the installation aisle being configured to install multiple server devices; and an air conditioning unit having an air supply vent and a return air vent, detachably connected to the container; the first end of the container having an air inlet and an air outlet; the air supply vent connecting to the cold aisle via the air inlet; and the hot aisle connecting to the return air vent via the air outlet.

[0006] Furthermore, there are one or more heat dissipation units, and the multiple heat dissipation units are arranged along the first direction and / or the second direction.

[0007] Furthermore, there are two heat dissipation units, which are arranged in the first direction and the second ends of the two containers are facing each other and connected; among them, two cold aisles are arranged correspondingly and two hot aisles are arranged correspondingly.

[0008] Furthermore, there are two heat dissipation units, which are arranged in the second direction, and the heat channels of the two containers are arranged facing each other and connected.

[0009] Furthermore, there are four heat dissipation units, which are arranged in rows and columns along the first and second directions. In the first direction, the second ends of two adjacent containers are arranged facing each other and connected, wherein two adjacent cold aisles are arranged correspondingly and two adjacent hot aisles are arranged correspondingly. In the second direction, the hot aisles of two adjacent containers are arranged facing each other and connected.

[0010] Furthermore, the air conditioning unit is a horizontal air conditioning unit.

[0011] Furthermore, the heat dissipation unit includes an air conditioning unit.

[0012] Furthermore, the heat dissipation unit includes multiple air conditioning units, which are arranged sequentially along the height of the container. The container is provided with multiple air inlets corresponding to multiple air supply outlets, and the container is also provided with multiple air outlets corresponding to multiple return air outlets.

[0013] Furthermore, the data center's cooling system also includes: a controller, with the air conditioning unit connected to the controller; at least one temperature control zone, each temperature control zone including at least one temperature sensor, the temperature sensor being connected to the controller, and the temperature sensor being located inside the container.

[0014] Furthermore, the data center's cooling system also includes at least one pressure control area. The pressure control area includes a differential pressure sensor, a positive pressure sampling pipe, and a negative pressure sampling pipe, all located inside the container. The positive pressure sampling pipe is located on the side where the air inlet is located, and the negative pressure sampling pipe is located on the side where the air outlet is located. The differential pressure sensor is connected to the controller and is used to detect the pressure difference between the positive pressure sampling pipe and the negative pressure sampling pipe.

[0015] By applying the technical solution of this utility model, cold air outside the data center's heat dissipation system flows from the air supply vent through the air inlet into the cold aisle, and then through the cold aisle into multiple installation channels. This dissipates heat from multiple server devices within the installation channels. The cold air exchanges heat with the server devices to form hot air, which then flows from the hot aisle through the air outlet to the return air vent, and is finally discharged from the heat dissipation system. This completes the cooling of multiple server devices. Compared to existing heat dissipation systems where the cold and hot aisles are not separated, this embodiment, by setting separate cold and hot aisles, avoids the mixing of cold and hot air. This avoids the need for excessive energy for cooling, thus preventing excessive energy consumption; furthermore, it improves the heat dissipation effect of the multiple server devices, preventing poor heat dissipation.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] It should be noted that, in the embodiments of this utility model, the first direction is... Figure 3 The length direction of container 20, and the second direction is Figure 4 The width and height of container 20 are as follows: Figure 3 As shown, the first direction, the second direction, and the height direction are set perpendicularly to each other.

[0042] like Figures 1 to 21 As shown, an embodiment of this utility model provides a heat dissipation system for a data center. The heat dissipation system for the data center includes at least one heat dissipation unit 1. The heat dissipation unit 1 includes: a container 20, which has a first end and a second end arranged opposite to each other along a first direction. The container 20 is provided with a cold aisle 15, an installation aisle, and a hot aisle 16 arranged sequentially and connected along a second direction. The cold aisle 15, the installation aisle, and the hot aisle 16 all extend from the first end to the second end. The installation aisle is configured to install multiple server devices 30. The first direction and the second direction are arranged at an angle. An air conditioning unit 10 has an air supply outlet 11 and a return air outlet 12. The air conditioning unit 10 is detachably connected to the container 20. The first end of the container 20 is provided with an air inlet and an air outlet. The air supply outlet 11 is connected to the cold aisle 15 through the air inlet, and the hot aisle 16 is connected to the return air outlet 12 through the air outlet.

[0043] In the above technical solution, cold air from outside the data center's cooling system flows from the air inlet 11 into the cold aisle 15, and then through the cold aisle 15 into multiple installation channels. This allows for the cooling of multiple server devices 30 within the installation channels. After exchanging heat with the server devices 30, the cold air forms hot air, which then flows from the hot aisle 16 through the air outlet to the return air outlet 12, and is finally discharged from the cooling system through the return air outlet 12. This completes the cooling of the multiple server devices 30. Compared to the prior art where the cold and hot aisles in the cooling system are not separated, this embodiment, by setting separate cold aisles 15 and hot aisles 16, avoids the mixing of cold and hot air. This avoids the need for more energy for cooling, thus preventing excessive energy consumption, and also improves the cooling effect of the multiple server devices 30, preventing poor cooling performance.

[0044] It should be noted that in the embodiments of this utility model, the cold air is the air outside the heat dissipation system of the data center. Compared with the air in the installation channel inside the data center, the temperature of the cold air is lower. The hot air is the air after the cold air has exchanged heat with multiple server devices 30. The temperature of the hot air is higher than that of the cold air.

[0045] Specifically, in the embodiments of this utility model, the air conditioning unit 10 includes a housing and two fans 13 disposed inside the housing. One fan 13 is disposed corresponding to the air supply port 11, and the other fan 13 is disposed corresponding to the air return port 12. In this way, under the action of the two fans 13, not only can the air outside the heat dissipation system flow from one fan 13 through the air supply port 11 into the cold aisle 15, but the hot air in the hot aisle 16 can also be discharged from the heat dissipation system through the air return port 12.

[0046] Specifically, in this embodiment of the invention, the data center's cooling system includes multiple bolts, the container 20 has multiple threaded holes, and the air conditioning unit 10 has multiple mounting angle irons 14, each with multiple threaded holes. The multiple mounting angle irons 14 are connected to the container 20 via multiple bolts. This allows for a detachable connection between the container 20 and the air conditioning unit 10, facilitating the disassembly and maintenance of the air conditioning unit 10.

[0047] like Figures 1 to 21 As shown in the embodiments of this utility model, there are one or more heat dissipation units 1, and the multiple heat dissipation units 1 are arranged along a first direction and / or a second direction. In this way, it can be adapted to data centers with different numbers of server devices 30.

[0048] like Figure 1 As shown in the embodiment of this utility model, the air conditioning unit 10 is a horizontal air conditioning unit.

[0049] In the above technical solution, the horizontal air conditioning unit has a flat structure. Compared with the vertical air conditioner, the horizontal air conditioning unit can be used in containers 20 with lower height. Furthermore, by adopting an integrated air conditioning unit 10, it is easy to install the air conditioning unit 10 on the container 20, thereby making the disassembly and maintenance of the air conditioning unit 10 more convenient.

[0050] like Figures 9 to 21 As shown in the embodiment of this utility model, the heat dissipation system of the data center further includes: a controller 17, an air conditioning unit 10 connected to the controller 17; at least one temperature control zone 41, each temperature control zone 41 including at least one temperature sensor, the temperature sensor being controlled and connected to the controller 17, and the temperature sensor being located inside the container 20.

[0051] In the above technical solution, the temperature sensor transmits the detected temperature to the controller 17. In this way, the controller 17 controls the air conditioning unit 10 to adjust the temperature of the temperature control area 41, so as to ensure the reliable operation of multiple server devices 30.

[0052] Specifically, in the embodiments of this utility model, the temperature control area 41 is the space where the cold aisle 15, the hot aisle 16 and multiple server devices 30 are located.

[0053] Preferably, in an embodiment of the present invention, the controller 17 is a central control box.

[0054] like Figures 9 to 21 As shown in the embodiment of this utility model, the heat dissipation system of the data center further includes at least one pressure control area. The pressure control area includes a differential pressure sensor, a sampling positive pressure pipe and a sampling negative pressure pipe, all located inside the container 20. The sampling positive pressure pipe is located on the side where the air inlet is located, and the sampling negative pressure pipe is located on the side where the air outlet is located. The differential pressure sensor is connected to the controller 17 for control, and the differential pressure sensor is used to detect the pressure difference between the sampling positive pressure pipe and the sampling negative pressure pipe.

[0055] In the above technical solution, by setting a differential pressure sensor, the pressure difference between the sampling positive pressure tube and the sampling negative pressure tube can be detected, thereby detecting the pressure difference between the air inlet and the air outlet. In this way, the controller 17 controls the air conditioning unit 10 to regulate the pressure inside the container 20.

[0056] Specifically, in the embodiments of this utility model, the sampling positive pressure tube is a device for gas sampling, which can ensure that the pressure inside the sample tube is higher than the pressure of the external environment during the sampling process.

[0057] Specifically, in embodiments of this utility model, the sampling negative pressure tube is typically used to extract gas samples from a pipeline under negative pressure conditions.

[0058] Example 1

[0059] like Figures 3 to 4 As shown, in Embodiment 1 of this utility model, there is one heat dissipation unit 1.

[0060] With the above configuration, cold air from outside the data center's cooling system flows from the air inlet 11 into the cold aisle 15, and then through the cold aisle 15 into multiple installation channels. This allows for the cooling of multiple server devices 30 within the installation channels. After exchanging heat with the multiple server devices 30, the cold air forms hot air, which then flows from the hot aisle 16 through the air outlet to the return air outlet 12, and is finally discharged from the cooling system through the return air outlet 12, thus completing the cooling and temperature reduction of the multiple server devices 30.

[0061] like Figure 3 and Figure 4As shown, in Embodiment 1 of this utility model, the heat dissipation unit 1 includes an air conditioning unit 10, that is, the air conditioning unit 10 is used as a single unit.

[0062] It should be noted that in the first embodiment of this utility model, the container 20 is formed by an upper plate, a lower plate and four side plates, the four side plates are arranged along the circumference of the container 20, and the air conditioning unit 10 is connected to one side plate of the container 20.

[0063] In one embodiment, such as Figures 5 to 8 As shown, the heat dissipation unit 1 may also include multiple air conditioning units 10, which are arranged sequentially along the height of the container 20. The container 20 is provided with multiple air inlets corresponding to multiple air outlets 11, and the container 20 is also provided with multiple air outlets corresponding to multiple air return outlets 12.

[0064] The above settings can be adapted to data centers with different numbers of server devices (30).

[0065] It should be noted that in Embodiment 1 of this utility model, one controller 17 can control a maximum of four temperature control zones 41, and one heat dissipation unit 1 can be configured with one to four temperature control zones 41, for example, as Figure 10 As shown, a container 20 is provided with a temperature-controlled area 41; or, for example, as Figure 11 As shown, a container 20 is provided with two temperature control zones 41, which are arranged sequentially along the first direction.

[0066] It should be noted that in the first embodiment of this utility model, one controller 17 can control a maximum of two pressure control areas, and one heat dissipation unit 1 can be set with one to two pressure control areas.

[0067] Example 2

[0068] The difference between this embodiment and embodiment one is that the number and arrangement of the heat dissipation units 1 are different, such as... Figure 12 As shown, there are two heat dissipation units 1, which are arranged in the first direction. The second ends of the two containers 20 are arranged facing each other and connected. Among them, two cold aisles 15 are arranged in a corresponding manner, and two hot aisles 16 are arranged in a corresponding manner.

[0069] With the above setup, two containers 20 can be spliced ​​together, and after splicing the two containers 20, the cold aisle 15 and the hot aisle 16 can be separated from each other, thereby improving the heat dissipation effect of multiple server devices 30, and also making the data center's heat dissipation system suitable for more server devices 30.

[0070] It should be noted that in the second embodiment of this utility model, during the splicing process of the two containers 20, one of the side panels on each container 20 (the side panel facing away from the air conditioning unit 10 along the first direction) needs to be disassembled before splicing. In this way, the cold aisle 15, the hot aisle 16 and the installation channel can be connected accordingly.

[0071] It should be noted that in Embodiment 2 of this utility model, the two heat dissipation units 1 can be provided with one to four temperature control zones 41, for example, as Figure 13 As shown, the two containers 20 are joined together to form a temperature-controlled area 41; or, for example, as Figure 14 As shown, the two containers 20 are equipped with two temperature-controlled zones 41, which are arranged sequentially along the first direction; or, as... Figure 15 As shown, the two containers 20 are equipped with three temperature-controlled zones 41, which are arranged sequentially along the first direction; or, as... Figure 16 As shown, the two containers 20 are provided with four temperature control zones 41, which are arranged sequentially along the first direction.

[0072] Similarly, the two heat dissipation units 1 can be configured with one or two pressure control zones.

[0073] The other structures in this second embodiment are the same as those in the first embodiment, and will not be described again here.

[0074] Example 3

[0075] The difference between this embodiment three and embodiment one lies in the number and arrangement of the heat dissipation units 1. Specifically, as shown in the example below... Figure 17 As shown, there are two heat dissipation units 1, which are arranged in the second direction. The heat channels 16 of the two containers 20 are arranged facing each other and connected.

[0076] In the above technical solution, cold air outside the heat dissipation system flows into the cold aisles 15 of the two containers 20 through the two air conditioning units 10. Then, the cold air in the two cold aisles 15 flows into the corresponding installation channels and cools the multiple server devices 30 in the installation channels. The resulting hot air then enters the two connected hot aisles 16. The hot air in the two hot aisles 16 flows through the air outlets of the two containers 20 to the two return air outlets 12 and is then discharged outside the heat dissipation system. In this way, the heat dissipation system can be used in heat dissipation centers with more server devices 30.

[0077] It should be noted that in Embodiment 3 of this utility model, during the splicing process of the two containers 20, one of the side panels (the side panel facing away from the cold aisle 15 along the second direction) on each container 20 needs to be disassembled before splicing, so that the two hot aisles 16 can be connected.

[0078] It should be noted that in Embodiment 3 of this utility model, the two heat dissipation units 1 can be provided with one to four temperature control zones 41, for example, as Figure 18 As shown, the two containers 20 are provided with two temperature control zones 41, which are arranged sequentially along the second direction.

[0079] Similarly, the two heat dissipation units 1 can be configured with one or two pressure control zones.

[0080] The other structures in this embodiment three are the same as those in embodiment one, and will not be described again here.

[0081] Example 4

[0082] The difference between this embodiment four and embodiment one is that the number and arrangement of the heat dissipation units 1 are different. Specifically, for example... Figure 19 As shown, there are four heat dissipation units 1, arranged in rows and columns along a first direction and a second direction. In the first direction, the second ends of two adjacent containers 20 are facing each other and connected, wherein two adjacent cold aisles 15 are correspondingly arranged and two adjacent hot aisles 16 are correspondingly arranged. In the second direction, the hot aisles 16 of two adjacent containers 20 are facing each other and connected. In this way, the heat dissipation system can be used in heat dissipation centers with more server devices 30, and can also be used in heat dissipation centers with different layouts of multiple server devices 30.

[0083] It should be noted that in Embodiment 4 of this utility model, during the splicing process of the four containers 20, the two adjacent side panels of each container 20 (the side panel away from the air conditioning unit 10 in the first direction and the side panel away from the cold aisle 15 in the second direction) need to be disassembled before splicing. In this way, the cold aisle 15, the hot aisle 16 and the installation channel in the first direction can be connected accordingly, and the two hot aisles 16 are connected in the second direction.

[0084] It should be noted that in Embodiment 4 of this utility model, the four heat dissipation units 1 can be provided with one to four temperature control zones 41, for example, as Figure 20 As shown, each of the four containers 20 has two temperature-controlled zones 41, which are arranged sequentially along the first direction; or, as... Figure 21 As shown, four temperature-controlled zones 41 are provided inside the four containers 20, and the four temperature-controlled zones 41 are arranged in rows along the first direction and along the second direction.

[0085] Similarly, the four heat dissipation units 1 can be configured with one or two pressure control zones.

[0086] The other structures in this embodiment four are the same as those in embodiment one, and will not be described again here.

[0087] In one embodiment, multiple controllers 17 can be set, thus allowing for more than four temperature control zones 41 and more than two pressure control zones.

[0088] It should be noted that, in the embodiments of this utility model, the installation, disassembly, and maintenance of the data center's heat dissipation system are relatively convenient, and the air conditioning unit 10 can be used as a single unit or stacked. Secondly, individual heat dissipation units 1 to four heat dissipation units 1 can be freely combined to form a data center's heat dissipation system, while simultaneously allowing for the separation of cold aisles 15 and hot aisles 16. Thirdly, the air conditioning unit 10 can achieve remote area temperature control and area pressure control functions, ensuring the reliable operation of the data center servers. This utility model realizes the application of data center scenarios; the air conditioning unit 10 is integrated, has a large cooling capacity, high energy efficiency, and possesses temperature and pressure control functions, facilitating various electrical system conversions and enabling mass production.

[0089] It should be noted that, in the embodiments of this utility model, the heat dissipation system of this data center can be controlled not only by a single controller 17, but also by multiple controllers 17 for centralized control. The controller 17 has remote temperature and area pressure control functions, which can meet the requirements of temperature uniformity in various areas of the data center and the reliability of server equipment 30. Specifically, the controller 17 can control up to four areas, collect the temperature of the four areas, and control the temperature of the space where up to sixteen server equipment 30 are located. That is, four server equipment 30 can be placed in each area. Remote area temperature control can be used in up to four areas, and each area can deploy up to sixteen temperature sensors for average temperature control or maximum temperature control. Remote area pressure control can be used in up to two areas.

[0090] It should be noted that, in the embodiments of this utility model, the heat dissipation system of this data center can provide a symmetrical unit supply and return air operation mode based on different installation positions, while keeping the working principle of the air conditioning unit 10 unchanged.

[0091] It should be noted that, in the embodiments of this utility model, the heat dissipation system of this data center can be used in intelligent terminal scenarios such as medical and health drug warehouses, IoT device data warehouses, unmanned driving data servers, and financial data processing, with the installation and control methods remaining unchanged.

[0092] It should be noted that in the embodiments of this utility model, during the combined use of one to four containers 20, each container 20 may be equipped with one or more air conditioning units 10, and the air conditioning units 10 are controlled by the controller 17 to achieve temperature and pressure control in the application scenario.

[0093] Specifically, in the embodiments of this utility model, this utility model has undergone rigorous experimental verification and long-term actual operation testing. The unit operates reliably and can effectively control the air temperature in the usage scenario.

[0094] It should be noted that the airflow path in each heat dissipation unit 1 is the same as in Embodiment 1, and does not change due to the number or layout of the heat dissipation units 1. For example, Figure 19 As shown, the airflow path in each heat dissipation unit 1 is as follows: outside the heat dissipation system → air outlet 11 of the air conditioning unit 10 → air inlet of the container 20 → cold aisle 15 → installation aisle → hot aisle 16 → air outlet of the container 20 → air return outlet 12 of the air conditioning unit 10 → outside the heat dissipation system.

[0095] It should be noted that, in the embodiments of this utility model, with the rapid development of mobile internet and the Internet of Things, new infrastructure can be deployed at the network edge. These facilities are located between the user end and the centralized cloud data center, which can reduce bandwidth and latency losses caused by network transmission and multi-level forwarding, and facilitate data processing. Data center infrastructure covers almost all industry sectors such as retail, healthcare, finance, and autonomous driving, providing more computing, network, and storage services closer to end users. At the same time, these facilities have fewer individual devices but more diverse equipment types. The data center cooling system of this utility model is easy to install, flexibly configure, highly energy-efficient, and easy to maintain, and can be adapted to the aforementioned data centers.

[0096] It should be noted that in the embodiments of this utility model, the number of pressure control areas and temperature control areas 41 are different, but the pressure control and temperature control methods are the same.

[0097] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: Cold air outside the data center's heat dissipation system flows from the air inlet to the cold aisle through the air outlet, and then flows through the cold aisle to multiple installation channels. In this way, multiple server devices in the installation channels can be cooled. After the cold air exchanges heat with the multiple server devices, it forms hot air. Then, the hot air flows from the hot aisle through the air outlet to the return air outlet, and then is discharged from the heat dissipation system outside the heat dissipation system, thereby completing the cooling and temperature reduction of multiple server devices. Compared with the prior art where the cold and hot aisles in the heat dissipation system are not separated, in this embodiment, by setting up separate cold and hot aisles, the phenomenon of cold air and hot air mixing can be avoided. On the one hand, this avoids the need for more energy for cooling, thus avoiding excessive energy consumption; on the other hand, it can also improve the heat dissipation effect of multiple server devices, thus avoiding the occurrence of poor heat dissipation effect.

[0098] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
