Description

Technical Field

[0001] This application relates to the field of data center cooling technology, and in particular to a liquid-cooled box and a containerized data center cooling system. Background Technology

[0002] With the rapid development of digital technology, people's demand for high-performance computing is growing. However, given the current computer hardware technology, high-performance computing also means high energy consumption, which is accompanied by the generation of high heat.

[0003] Data center cooling is a key technology for ensuring the continuous and stable operation of electronic equipment within a data center. Servers, storage devices, network hardware, and other electronic equipment generate significant heat during operation; if left uncontrolled, this heat can lead to overheating, impaired performance, and even equipment damage. Therefore, effective cooling measures have a substantial impact on the energy efficiency, reliability, and operating costs of a data center.

[0004] Traditional data center cooling systems primarily rely on air cooling, resulting in low energy efficiency. Immersion-style single-phase liquid cooling can significantly improve heat dissipation efficiency and reduce energy consumption. Immersion-style liquid cooling requires immersing the server in a enclosure filled with an insulating coolant (such as transformer oil), allowing the coolant's flow to remove heat.

[0005] However, when there are a large number of servers in the liquid-cooled enclosure, the difference in local flow will lead to inconsistent heat dissipation effects for servers in different locations, which can easily cause some servers to overheat and stop working. Utility Model Content

[0006] The purpose of this application is to provide a liquid-cooled box and a containerized data center cooling system that can make the heat dissipation and cooling effect of various electronic devices such as servers more consistent, thereby reducing the risk of local servers stopping work due to high temperature.

The top wall of each inlet pipe is provided with a plurality of inlet holes. The inner side wall of the liquid cooling box body and the top wall of all the inlet pipes form the liquid cooling cavity.

[0016] In an optional embodiment, an inlet is provided on the side wall of the liquid-cooled box in the area corresponding to the liquid inlet chamber.

[0017] In an optional embodiment, the diameter of the inlet orifice gradually increases from the region of the inlet chamber near the inlet to the region away from the inlet.

[0018] In an optional embodiment, the liquid cooling box further includes a diversion shell and a diversion component. The diversion shell is connected to the outer wall of the liquid cooling box and forms a diversion cavity with the outer wall of the liquid cooling box. An inlet is provided on the side wall of the liquid cooling box in the area corresponding to the liquid inlet cavity so that the diversion cavity communicates with the liquid inlet cavity. The diversion shell is provided with a liquid delivery port.

[0019] The flow divider is disposed in the flow divider cavity to divide the coolant entering from the liquid inlet into multiple streams.

[0020] In an optional embodiment, the liquid inlet is located at the top of the diversion housing; the diversion component includes a first diversion plate and a second diversion plate;

[0021] The opposite sides of the first diversion plate are respectively connected to the outer wall of the liquid cooling box and the inner wall of the diversion shell; the opposite sides of the second diversion plate are respectively connected to the outer wall of the liquid cooling box and the inner wall of the diversion shell.

[0022] The first flow divider and the second flow divider are located on both sides of the central axis of the liquid delivery port, and the distance between the top of the first flow divider and the top of the second flow divider is less than the distance between the bottom of the second flow divider and the bottom of the second flow divider.

[0024] In an optional embodiment, the liquid cooling chamber is divided into multiple parallel liquid cooling zones, and the liquid cooling box also has a dispersion chamber located between the liquid inlet chamber and the liquid cooling chamber.

[0026] Compared with the prior art, the beneficial effects of the embodiments of this application include, for example:

[0027] After densely arranging multiple servers and other electronic devices inside the liquid cooling cavity, the coolant supplied to the inlet cavity can be distributed more evenly to all parts of the cavity. When the coolant enters the liquid cooling cavity through the small inlet holes, the reduced flow area allows for the formation of multiple coolant jets with similar flow rates and velocities. This ensures that the servers and other electronic devices in different locations within the liquid cooling cavity receive a more even flow of coolant during operation, resulting in more consistent heat dissipation and cooling effects across all servers and other electronic devices. This reduces the risk of localized server overheating and shutdown. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] This application discloses a containerized data center cooling system, which includes a container and a liquid cooling box and a heat dissipation device located inside the container. The heat dissipation device and the liquid cooling box form a coolant circuit to realize the circulation of coolant. The heat dissipation device is mainly used to dissipate and cool down the coolant discharged from the liquid cooling box and then return it to the liquid cooling box to achieve continuous cooling of electronic equipment such as servers inside the liquid cooling box.

[0045] Combination Figures 1 to 3 The liquid cooling box has a liquid inlet chamber 40 and a liquid cooling chamber 50 arranged in parallel, and the liquid inlet chamber 40 and the liquid cooling chamber 50 are connected by a plurality of liquid inlet holes 21.

[0046] In this way, after multiple servers and other electronic devices are densely arranged in the liquid cooling cavity 50, the coolant delivered to the liquid inlet cavity 40 can be distributed more evenly to all parts of the liquid inlet cavity 40. Then, when the coolant enters the liquid cooling cavity 50 through each liquid inlet hole 21, the flow area is reduced, which can form multiple coolant jets with similar flow rates and velocities. This allows the servers and other electronic devices in different positions in the liquid cooling cavity 50 to receive more equal coolant flow opportunities when they are working, making the heat dissipation and cooling effect of each server and other electronic device more consistent, thereby reducing the risk of local servers overheating and stopping.

[0047] Specifically, to form the liquid inlet chamber 40 and the liquid cooling chamber 50, in this embodiment, the liquid cooling box includes a liquid cooling box body 10 and a bottom plate 20 connected to the inner wall of the liquid cooling box body 10. A gap is left between the bottom plate 20 and the bottom wall of the liquid cooling box body 10 to divide the internal space of the liquid cooling box body 10 into the liquid inlet chamber 40 and the liquid cooling chamber 50. The liquid inlet chamber 40 is located below the liquid cooling chamber 50, meaning the liquid inlet chamber 40 and the liquid cooling chamber 50 are arranged side-by-side in the vertical direction. The bottom plate 20 is provided with a plurality of evenly distributed liquid inlet holes 21. The bottom plate 20 and the inner wall of the liquid cooling box body 10 can be integrally connected or separately connected by welding. Of course, in some embodiments, the liquid inlet chamber 40 and the liquid cooling chamber 50 can also be arranged side-by-side in the horizontal direction.

[0048] Optionally, there are multiple ribs 30 evenly distributed between the base plate 20 and the bottom wall of the liquid cooling box 10. The opposite sides of the ribs 30 are connected to the base plate 20 and the bottom wall of the liquid cooling box 10, respectively. Each rib 30 divides the liquid inlet chamber 40 into multiple parallel liquid inlet channels 41. Each liquid inlet channel 41 is connected to the liquid cooling box 50 through multiple liquid inlet holes 21. In this way, the bottom of the liquid cooling box can be formed into a structure similar to multiple square tubes arranged in parallel through the ribs 30, thereby improving the strength of the bottom of the liquid cooling box and having a greater load-bearing capacity, so as to support more and denser servers, save space, and at the same time ensure that the coolant can enter the liquid cooling box 50 evenly from each liquid inlet channel 41 through the corresponding liquid inlet holes 21.

[0049] The liquid cooling enclosure 10 is roughly rectangular, which can be either a rectangle or a square. An inlet 11 is located on the short side wall of the liquid cooling enclosure 10, corresponding to the area of ​​the liquid inlet chamber 40. One end of the rib 30 corresponds to the inlet 11. The length direction of the rib 30 is the same as the length direction of the liquid cooling enclosure 10. This allows the coolant entering through the inlet 11 to be evenly distributed into each liquid inlet channel 41, and then enters the liquid cooling chamber 50 through the inlet hole 21, thus ensuring consistent heat dissipation for each server.

[0050] Of course, in other embodiments, the shape of the liquid cooling housing 10 is not limited to a rectangle, but may be elliptical or the like.

[0051] Optionally, at least two rows of small inlet holes 21 are distributed on the base plate 20 corresponding to each liquid inlet channel 41. The arrangement direction of each row of small inlet holes 21 is the same as the length direction of the rib 30, so as to uniformly introduce coolant into the liquid cooling cavity 50.

[0052] It should be noted that in some embodiments, the rib 30 may also be a curved extension or a zigzag extension, and protrusions or grooves may be provided on its surface. Alternatively, the rib 30 may not be provided, so that the bottom of the liquid cooling box is a sheet metal double-layer structure.

[0053] In this embodiment, the diameter of the inlet orifice 21 gradually increases from the area of ​​the base plate 20 near the liquid inlet 11 to the area away from the liquid inlet 11, that is, from the area of ​​the liquid inlet cavity 40 near the liquid inlet 11 to the area away from the liquid inlet 11. This is to match the objective phenomenon that the coolant flow rate is large in the area of ​​the liquid inlet cavity 40 near the liquid inlet 11 and small in the area away from the liquid inlet 11. In this way, the diameter of the inlet orifice 21 is small in the area with large coolant flow rate and large in the area with small coolant flow rate. This makes the flow rate and speed of coolant entering the liquid cooling cavity 50 from all places similar, thereby making the heat dissipation effect of each server more uniform.

[0054] Of course, in some embodiments, the diameter of all the liquid inlet holes 21 on the base plate 20 can be kept the same to reduce the number of processing steps.

[0055] In embodiments not shown, multiple pipes can be arranged in parallel to form the liquid inlet chamber 40. For example, the liquid cooling box includes a liquid cooling box body 10 and a liquid inlet pipe assembly connected to the bottom of the liquid cooling box body 10. The liquid inlet pipe assembly includes multiple liquid inlet pipes connected in parallel. The internal space of each liquid inlet pipe serves as a liquid inlet channel 41. The internal space of all liquid inlet pipes (liquid inlet channels 41) together serve as the liquid inlet chamber 40. The top wall of each liquid inlet pipe is provided with multiple liquid inlet holes 21. The inner side wall of the liquid cooling box body 10 and the top wall of all liquid inlet pipes form a liquid cooling chamber 50.

[0056] The inlet pipe can be either a square or round pipe, and the connection between two adjacent inlet pipes can be by welding.

[0057] Furthermore, in order to ensure that the cooling flow rates in the middle and edge regions of the inlet 11 are as similar as possible, the liquid cooling tank also includes a distribution shell 60 and a distribution element, combined with Figure 4 The diversion shell 60 is connected to the outer wall of the liquid cooling box 10 and forms a diversion cavity 62 with the outer wall of the liquid cooling box 10. An inlet 11 is provided on the side wall of the liquid cooling box 10 in the area corresponding to the liquid inlet cavity 40 so that the diversion cavity 62 communicates with the liquid inlet cavity 40. The diversion shell 60 is provided with a liquid delivery port 61. A diversion component is provided in the diversion cavity 62 so that the coolant entering from the liquid delivery port 61 is divided into multiple streams, thereby homogenizing the coolant flow rate.

[0058] Specifically, the diversion components include a first diversion plate 70 and a second diversion plate 71. The opposite sides of the first diversion plate 70 are connected to the outer wall of the liquid cooling box 10 and the inner wall of the diversion shell 60, respectively. The opposite sides of the second diversion plate 71 are connected to the outer wall of the liquid cooling box 10 and the inner wall of the diversion shell 60, respectively. In this way, the coolant entering from the liquid inlet 61 can be divided into three streams through the first diversion plate 70 and the second diversion plate 71. One stream enters from the middle area of ​​the liquid inlet 11, and the other two streams are respectively directed to the edge area of ​​the liquid inlet 11. This ensures the uniformity of the liquid inlet cavity 40 in the width direction of the liquid cooling box, thereby ensuring the consistency of the heat dissipation effect of the servers in various places.

[0059] exist Figure 4 In the illustrated embodiment, there is one flow divider housing 60, one flow divider component, and one liquid inlet 11. However, in some embodiments, there may be two flow divider housings 60, flow dividers, and two liquid inlets 11, located on both sides of the length of the liquid cooling box 10, so that oil can enter the liquid inlet chamber 40 from both sides at the same time.

[0060] The liquid inlet holes 21 on the base plate 20 can be evenly distributed as shown in the figure, or they can be specifically distributed according to the heat source location of each server, that is, they can be non-uniformly distributed.

[0061] Of course, the liquid cooling housing 10 has a drain port 12 communicating with the liquid cooling cavity 50. There can be one or more drain ports 12, and their specific distribution can be set according to actual needs. This embodiment does not limit this. The flow divider can also be an arc-shaped plate that protrudes toward the liquid inlet 61, and the flow divider has an opening in the middle, which can also realize the multi-stream flow of coolant.

[0062] In some embodiments, combined with Figure 5 and Figure 6The diversion housing 60 can be tubular, with the liquid inlet 61 located at the end of the diversion housing 60. The diversion component includes a central column 65 and multiple guide plates 72 circumferentially spaced on the outside of the central column 65. Each guide plate 72 divides the diversion cavity 62 into multiple diversion channels 63. The diversion housing 60 is provided with multiple diversion ports 64 so that each diversion channel 63 communicates with the liquid inlet cavity 40 through the diversion port 64.

[0063] Specifically, the number of diversion channels 63 is the same as the number of inlet channels 41. Each diversion port 64 connects a diversion channel 63 with an inlet channel 41. The guide plate 72 can extend in a spiral shape around the central column 65, which can also realize the diversion of the coolant injected from the liquid inlet 61 into multiple streams before being sent into the liquid inlet chamber 40, ensuring uniform liquid intake.

[0064] It should also be noted that, in some embodiments, references Figure 7 The liquid cooling chamber 50 is divided into multiple parallel liquid cooling zones 51. The liquid cooling box also has a dispersion chamber 80 located between the liquid inlet chamber 40 and the liquid cooling chamber 50. The dispersion chamber 80 has multiple non-interconnected dispersion zones 81. The liquid inlet chamber 40 is connected to each dispersion zone 81 through multiple liquid inlet holes 21. Each dispersion zone 81 is connected to a corresponding liquid cooling zone 51 through multiple dispersion holes 84. In this way, by adding another layer of dispersion chamber 80 between the liquid inlet chamber 40 and the liquid cooling chamber 50, the flow of coolant can be divided, and the uniformity of liquid inlet can also be ensured.

[0065] Furthermore, electronic thermal backup devices with different power consumptions can be placed in the liquid cooling zone 51. For example, devices with slightly higher heat generation can be placed in some liquid cooling zones 51 closer to the liquid inlet 11, while devices with slightly lower heat generation can be placed in some liquid cooling zones 51 farther away from the liquid inlet 11, so as to meet the heat exchange requirements of different devices.

[0066] The dispersion cavity 80 can be formed as follows: a dispersion plate 82 is provided on the upper side of the bottom plate 20 or the liquid inlet pipe assembly. The dispersion plate 82 is connected to the inner wall of the liquid cooling box 10, thus forming a dispersion cavity 80 between the dispersion plate 82 and the bottom plate 20 (or the liquid inlet pipe assembly). The space between the dispersion plate 82 and the inner wall of the liquid cooling box 10 serves as a liquid cooling cavity 50. At the same time, multiple vertical plates 83 are provided between the dispersion plate 82 and the bottom plate 20 (or the liquid inlet pipe assembly) at intervals along the length of the liquid cooling box 10. Thus, the dispersion cavity 80 is divided into multiple dispersion areas 81 by the multiple vertical plates 83. At the same time, multiple dispersion holes 84 are provided on the dispersion plate 82 to realize the communication between each dispersion area 81 and a corresponding liquid cooling area 51.

[0067] The liquid cooling zone 51 can be divided into multiple liquid cooling zones 51 by providing multiple partitions 52 arranged at intervals along the length of the liquid cooling chamber 10 in the liquid cooling cavity 50.

[0068] In summary, this application discloses a liquid-cooled box and a containerized data center cooling system. After multiple servers and other electronic devices are densely arranged in the liquid-cooled cavity 50, the coolant delivered to the liquid inlet cavity 40 can be distributed relatively evenly to all parts of the liquid inlet cavity 40. Then, when the coolant enters the liquid-cooled cavity 50 through each liquid inlet hole 21, the flow area is reduced, which can form multiple coolant jets with similar flow rates and velocities. This allows the servers and other electronic devices in different positions within the liquid-cooled cavity 50 to receive more equal coolant flow opportunities during operation, making the heat dissipation and cooling effect of each server and other electronic device more consistent, thereby reducing the risk of local servers overheating and stopping operation.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
