Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling equipment, and in particular to a liquid cooling box and a containerized cooling system. Background Art

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

[0003] Data center cooling is one of the key technologies to ensure that electronic equipment inside the data center can operate continuously and stably. Since servers, storage devices, network hardware and other electronic equipment generate a lot of heat during operation, if it is not controlled, it will cause the equipment to overheat, affect performance, and even cause equipment damage. Therefore, effective cooling measures have a significant impact on the energy efficiency, reliability and operating costs of the data center.

[0004] Traditional data center cooling systems are mainly air-cooled, which has low energy utilization. The immersion single-phase liquid cooling mode can greatly improve the heat dissipation efficiency and reduce energy consumption. The immersion liquid cooling mode requires the server to be immersed in a box, and an insulating coolant (such as transformer oil) is injected to remove heat through the flow of the coolant.

[0005] However, on the one hand, once there are a large number of servers in the liquid cooling box, the difference in local flow rates among servers at different locations will lead to inconsistent heat dissipation effects, which may easily cause local servers to stop working due to high temperatures; on the other hand, the current drain port of the liquid cooling box is directly connected to the liquid cooling chamber used to immerse and cool electronic equipment. The coolant in various places in the liquid cooling chamber can only be discharged when it is gathered near the drain port. The discharge is not smooth, which affects the heat dissipation efficiency of the electronic equipment. Summary of the invention

[0066] Combine the following Figures 1 to 9 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0067] An embodiment of the present application discloses a container-type cooling system, which includes a container and a liquid cooling box and a heat dissipation device located in the container. A coolant circuit is formed between the heat dissipation device and the liquid cooling box to realize the circulation of the coolant. The heat dissipation device is mainly used to dissipate the heat and cool 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 in the liquid cooling box.

[0068] refer to Figures 1 to 3 The liquid cooling box has a liquid inlet chamber 11 and an immersion chamber, a partition plate 30 is arranged in the immersion chamber, the immersion chamber is divided into a liquid cooling chamber 12 and a liquid discharge chamber 13, the liquid inlet chamber 11 and the liquid cooling chamber 12 are connected through a plurality of liquid inlet holes 21, and the liquid cooling chamber 12 is connected with the liquid discharge chamber 13 through a plurality of overflow ports 31.

[0069] In this way, after a plurality of servers and other electronic devices are densely arranged in the liquid cooling chamber 12, the cooling liquid transported to the liquid inlet chamber 11 can be more evenly transferred to various places in the liquid inlet chamber 11. Since the liquid inlet chamber 11 can be connected to the liquid cooling chamber 12 through a plurality of liquid inlet holes 21, the cooling liquid at various places in the liquid inlet chamber 11 enters the liquid cooling chamber 12 from each liquid inlet hole 21, so that the electronic devices at various positions in the liquid cooling chamber 12 can obtain a more equal cooling liquid injection opportunity when working, so that the heat dissipation and cooling effects of various servers and other electronic devices are close to the same, so as to reduce the risk of causing the local server to stop working due to high temperature. In addition, since the liquid cooling chamber 12 and the drainage chamber 13 are connected through a plurality of overflow ports 31, the cooling liquid in the liquid cooling chamber 12 can flow into the drainage chamber 13 in an overflow manner through the overflow port 31, and then be discharged through the drainage port 15, so that the cooling liquid in the liquid cooling chamber 12 can be smoothly discharged into the drainage chamber 13, thereby ensuring the heat dissipation efficiency of the electronic equipment.

[0070] In this embodiment, the liquid cooling box includes a liquid cooling box body 10 and a bottom plate 20 and a partition plate 30 located in the internal space of the liquid cooling box body 10. The outer edge of the bottom plate 20 is connected to the inner wall of the liquid cooling box body 10 to divide the internal space of the liquid cooling box body 10 into a liquid inlet chamber 11 and an immersion chamber. The liquid inlet chamber 11 is located below the immersion chamber. The outer edge of the partition plate 30 is connected to the inner wall of the liquid cooling box body 10 and the bottom plate 20, that is, the bottom edge of the partition plate 30 is connected to the bottom plate 20, and the two side edges of the partition plate 30 in the length direction are connected to the inner wall of the liquid cooling box body 10. The partition plate 30 The bottom plate 20 is at an angle, which can be a vertical right angle or an acute angle, so that the partition plate 30 can divide the immersion chamber into a liquid cooling chamber 12 and a liquid discharge chamber 13 in parallel in the horizontal direction, wherein the bottom plate 20 corresponding to the liquid cooling chamber 12 is provided with a plurality of liquid inlet holes 21 penetrating therethrough, the partition plate 30 is provided with a plurality of overflow ports 31 penetrating therethrough, and the side wall of the liquid cooling box 10 corresponding to the liquid discharge chamber 13 is provided with a liquid discharge port 15 penetrating therethrough, and the connection method of the bottom plate 20, the partition plate 30 and the liquid cooling box 10 can be an integrated connection or a split connection such as welding. The horizontal direction is the width direction of the liquid cooling box 10.

[0071] Of course, in some embodiments, the liquid inlet chamber 11 and the immersion chamber may also be arranged in parallel in the horizontal direction, and the liquid discharge chamber 13 may also be located below the liquid cooling chamber 12 .

[0072] Thus, in this embodiment, the internal space of the liquid cooling box 10 is divided into a liquid inlet chamber 11 and an immersion chamber by the bottom plate 20, and the immersion chamber is divided into a liquid cooling chamber 12 and a liquid discharge chamber 13 by the partition plate 30. In this way, after a plurality of servers and other electronic devices are densely arranged in the liquid cooling chamber 12, the cooling liquid delivered to the liquid inlet chamber 11 can be more evenly transmitted to various places in the liquid inlet chamber 11. Since a plurality of penetrating liquid inlet holes 21 are provided in the area corresponding to the liquid cooling chamber 12 on the bottom plate 20, when the cooling liquid at various places in the liquid inlet chamber 11 enters the liquid cooling chamber 12 from each liquid inlet hole 21, a plurality of cooling liquid jets with similar flow rates and velocities will be formed due to the reduction in the flow area. Therefore, the servers and other electronic devices at various positions in the liquid cooling chamber 12 can obtain more equal cooling liquid injection opportunities when working, so that the heat dissipation and cooling effects of the servers and other electronic devices are close to the same, so as to reduce the risk of causing the local server to stop working due to high temperature. In addition, since the partition plate 30 is provided with a plurality of overflow ports 31 passing through the partition plate 30, the coolant in the liquid cooling chamber 12 can flow into the drain chamber 13 through the overflow port 31 in an overflow manner, and then be discharged through the drain port 15. In this way, the coolant in the liquid cooling chamber 12 can be smoothly discharged into the drain chamber 13, thereby ensuring the heat dissipation efficiency of the electronic equipment.

[0073] Optional, combined Figures 4 to 6 There are multiple ribs 22 evenly distributed between the bottom plate 20 and the bottom wall of the liquid cooling box 10, and the opposite sides of the ribs 22 are respectively connected to the bottom plate 20 and the bottom wall of the liquid cooling box 10, that is, the bottom edge of the rib 22 is connected to the bottom wall of the liquid cooling box 10, and the top edge of the rib 22 is connected to the bottom plate 20. Each rib 22 divides the liquid inlet cavity 11 into a plurality of parallel liquid inlet channels 110, and each liquid inlet channel 110 is connected to the liquid cooling cavity 12 through a plurality of liquid inlet holes 21. In this way, through the plurality of ribs 22, the bottom of the liquid cooling box can form a structure similar to a plurality of square tubes arranged in parallel, thereby improving the strength of the bottom of the liquid cooling box and having a greater load-bearing capacity, so as to be able to carry a larger and denser number of servers, save space, and at the same time ensure that the coolant can evenly enter the liquid cooling cavity 12 from each liquid inlet channel 110 through the corresponding liquid inlet holes 21.

[0074] The liquid cooling box 10 is roughly rectangular, which can be a rectangle or a square. The bottom plate 20 is roughly parallel to the bottom wall of the liquid cooling box 10. The liquid inlet 14 is located on one side of the length direction of the liquid discharge cavity 13, that is, the liquid inlet 14 is set on the short side wall of the liquid cooling box 10 in the area corresponding to the liquid inlet cavity 11, and one end of the rib 22 corresponds to the liquid inlet 14. The length direction of the rib 22 is the same as the length direction of the liquid cooling box 10, so that the coolant entering through the liquid inlet 14 can be relatively evenly passed into each liquid inlet channel 110, and then enter the liquid cooling cavity 12 from the liquid inlet hole 21, thereby ensuring the consistency of the heat dissipation effect of each server.

[0075] Optionally, at least two rows of liquid inlet holes 21 are distributed in the area corresponding to each liquid inlet channel 110 on the bottom plate 20 , and the arrangement direction of each row of liquid inlet holes 21 is the same as the length direction of the rib 22 , so as to evenly allow coolant to flow into the liquid cooling cavity 12 .

[0076] It should be noted that, in some embodiments, the ribs 22 may extend in a curved shape or a folded line, and protrusions or grooves may be provided on the surface thereof. In addition, the ribs 22 may not be provided, so that the bottom of the liquid cooling box is a double-layer sheet metal structure.

[0077] In this embodiment, the aperture of the liquid inlet hole 21 gradually increases from the area of ​​the bottom plate 20 close to the liquid inlet 14 to the area far from the liquid inlet 14. This is to match the phenomenon that the coolant flow rate in the area close to the liquid inlet 14 in the liquid inlet cavity 11 is large, while the coolant flow rate in the area far from the liquid inlet 14 is small. In this way, the aperture of the liquid inlet hole 21 in the area with large coolant flow rate is small, and the aperture of the liquid inlet hole 21 in the area with small coolant flow rate is large. In this way, the coolant flow rate and speed entering the liquid cooling cavity 12 from various places can be similar, so that the heat dissipation effect of each server can be more uniform.

[0078] Of course, in some embodiments, the apertures of all liquid inlet holes 21 on the bottom plate 20 may also be kept consistent to reduce the number of processing steps.

[0079] In an embodiment not shown in the figure, a structure in which multiple pipes are arranged in parallel as the liquid inlet chamber 11 can also be adopted. 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 and a partition plate 30 located inside the liquid cooling box body 10. The liquid inlet pipe assembly includes multiple liquid inlet pipes connected in parallel, and the internal space of each liquid inlet pipe serves as a liquid inlet channel 110. The internal spaces of all liquid inlet pipes (liquid inlet channels 110) together serve as the liquid inlet chamber 11. A plurality of liquid inlet holes 21 are arranged on the top wall of each liquid inlet pipe. The inner wall of the liquid cooling box body 10 and the top walls of all liquid inlet pipes form a liquid cooling chamber 12. The partition plate 30 is connected to the top side of the liquid inlet pipe assembly and the inner wall of the liquid cooling box body 10 to separate the immersion chamber into the liquid cooling chamber 12 and the drainage chamber 13.

[0080] The liquid inlet pipe may be a square pipe or a round pipe, and the connection method of two adjacent liquid inlet pipes may be welding.

[0081] In addition, in order to make the cooling flow rate of the middle area and the edge area of ​​the liquid inlet 14 as close as possible, the liquid cooling box also includes a flow splitter housing 40 and a flow splitter. Figure 1 and Figure 4The diverter shell 40 is connected to the outer wall of the liquid cooling box 10, and encloses a diverter cavity 42 with the outer wall of the liquid cooling box 10. A liquid inlet 14 is arranged on the side wall of the liquid cooling box 10 in an area corresponding to the liquid inlet cavity 11, so that the diverter cavity 42 is connected with the liquid inlet cavity 11. The diverter shell 40 is provided with a liquid delivery port 41, and a diverter is arranged in the diverter cavity 42, so that the coolant entering from the liquid delivery port 41 is divided into multiple streams, thereby homogenizing the coolant flow.

[0082] Specifically, the diverter includes a first diverter plate 43 and a second diverter plate 44; the first diverter plate 43 and the second diverter plate 44 are located in the diverter cavity 42, and the opposite sides of the first diverter plate 43 are respectively connected to the outer wall of the liquid cooling box 10 and the inner wall of the diverter shell 40, and the opposite sides of the second diverter plate 44 are respectively connected to the outer wall of the liquid cooling box 10 and the inner wall of the diverter shell 40, so that the first diverter plate 43 and the second diverter plate 44 can divide the cooling liquid introduced from the liquid delivery port 41 into three streams, one stream is introduced from the middle area of ​​the liquid inlet 14, and the other two streams are respectively introduced into the edge areas of the liquid inlet 14, thereby ensuring the uniformity of the liquid inlet cavity 11 at various locations in the width direction of the liquid cooling box, and then ensuring the consistency of the heat dissipation effect of the servers at various locations.

[0083] exist Figure 4 In the embodiment shown, the number of the diverter housing 40, the diverter member and the liquid inlet 14 is one, but in some embodiments, the number of the diverter housing 40, the diverter member and the liquid inlet 14 may be at least two, which are respectively located on both sides of the length direction of the liquid cooling box 10, so that the coolant enters both sides evenly at the same time.

[0084] The liquid inlet hole 21 on the bottom plate 20 can be Figure 1 and Figure 3 The uniform distribution shown may also be a targeted specific distribution according to the heat source location of each server, that is, it may be a non-uniform distribution.

[0085] The flow divider may also be in the shape of an arc-shaped plate, which protrudes toward the liquid delivery port 41, and a hole is opened in the middle of the flow divider, so that multiple flows of the coolant can be realized.

[0086] In some embodiments, in combination Figure 6 , Figure 8 and Fig. 9 The diverter housing 40 is tubular, the liquid delivery port 41 is located at the end of the diverter housing 40, the diverter member includes a center column 45 and a plurality of guide plates 46 circumferentially spaced and connected to the outside of the center column 45, each of the guide plates 46 divides the diverter chamber 42 into a plurality of diverter channels 34, and the diverter housing 40 is provided with a plurality of liquid diversion ports 35, so that each of the diverter channels 34 is connected to the liquid inlet chamber 11 through the liquid diversion port 35.

[0087] Specifically, the number of diversion channels 34 is the same as the number of liquid inlet channels 110, and each liquid diversion port 35 connects a diversion channel 34 with a liquid inlet channel 110. The guide plate 46 can extend in a spiral shape around the central column 45, so that the coolant injected from the liquid delivery port 41 can be diverted into multiple streams and then delivered into the liquid delivery chamber to ensure uniform liquid inflow.

[0088] The partition plate 30 can be specifically arranged vertically in the internal space of the liquid cooling box 10, the length direction of the partition plate 30 and the length direction of the bottom plate 20 are the same as the length direction of the liquid cooling box 10, and the thickness direction of the partition plate 30 is along the width direction of the liquid cooling box 10, so that the length directions of the liquid cooling chamber 12 and the drainage chamber 13 are also along the length direction of the liquid cooling box 10. The overflow ports 31 are arranged at intervals along the length direction of the partition plate 30, so that the liquid cooling chamber 12 and the drainage chamber 13 can be arranged side by side in the horizontal direction.

[0089] Of course, in other embodiments, the shape of the liquid cooling box 10 is not limited to a rectangle, for example, an ellipse, etc.

[0090] In this embodiment, combined with Figure 1 and Figure 6 The drain port 15 is located on at least one side of the drain cavity 13 in the length direction. Since the area closer to the drain port 15 in the drain cavity 13 gathers more coolant, in this embodiment, the depth of the drain cavity 13 gradually increases from the side of the drain port 15 close to the drain port 15 to the side away from the drain port 15, so that the coolant can be better accommodated.

[0091] In order to achieve a gradual change in the depth of the drainage cavity 13, the bottom wall of the liquid cooling box 10 used to form the drainage cavity 13 can be set to a slope structure. Alternatively, a concave drainage groove can be directly set on the bottom wall of the liquid cooling box 10, and along the length direction of the drainage cavity 13, the closer to the drainage port 15, the greater the depth of the drainage groove.

[0092] In addition, in other embodiments, the partition plate 30 may be tilted so that the width of the drainage chamber 13 near the drainage port 15 is larger, which can also improve the problem of high flow pressure of the coolant near the drainage port 15 .

[0093] In the illustrated embodiment, there is only one drainage port 15 located at one side of the drainage cavity 13 in the length direction, and there is only one partition plate 30 , so there is only one drainage cavity 13 .

[0094] Of course, two or more drain ports 15 may be provided; for example, the two drain ports 15 are respectively located on both sides of the length direction of the drain cavity 13, that is, the drain ports 15 are provided at both ends of the length direction of the liquid cooling box 10, and the depth of the drain cavity 13 gradually increases from the middle to both ends of the drain cavity 13, and the drain pipe 50 may be correspondingly cancelled. If there are more than three drain ports 15, then at least one additional drain port 15 may be provided on one side of the width direction of the liquid cooling box 10, that is, on one side of the width direction of the drain cavity 13.

[0095] In addition, the drain ports 15 may be provided only on both sides of the drain chamber 13 in the width direction.

[0096] In other embodiments, the number of the partition plates 30 may also be two, so that the two partition plates 30 divide the internal space of the liquid cooling box 10 into a central liquid cooling chamber 12 and drainage chambers 13 located on both sides of the liquid cooling chamber 12 in the width direction.

[0097] In this embodiment, combined with Figure 1 , Figure 2 and Figure 7 Since the liquid inlet chamber 11 is located below the liquid cooling chamber 12, the coolant enters from the bottom of the liquid cooling chamber 12. Therefore, in order to adapt to this structure, the overflow port 31 is set at the upper part of the partition plate 30 and extends to the top edge of the partition plate 30, that is, extends to the side of the partition plate 30 away from the bottom wall of the liquid cooling box body 10. In this way, the coolant needs to flow upward for a distance after entering before it can flow from the overflow port 31 to the drain chamber 13, so as to ensure that the coolant can pass a longer distance in the liquid cooling chamber 12 and better contact with the electronic equipment to take away heat.

[0098] The overflow port 31 may be a notch 62 structure or a through hole structure.

[0099] In the present embodiment, since there is only one drain port 15 and since the drain port 15 is located on one side of the length direction of the drain cavity 13, the coolant flow rate in the area closer to the drain port 15 in the drain cavity 13 is faster, while the coolant flow rate in the area farther from the drain port 15 is slower, which will cause the liquid level in the drain cavity 13 far away from the drain port 15 to be flush with the liquid cooling cavity 12, causing the liquid flow to be chaotic and affecting the heat dissipation effect. In order to improve this problem, therefore, in the present embodiment, the liquid cooling box further includes a drainage pipe 50 and a diverter plate 32. The drainage pipe 50 is arranged on the outer side of the side wall of the liquid cooling box body 10 for forming the drainage chamber 13; that is, the drainage pipe 50 is away from the liquid cooling chamber 12 relative to the drainage chamber 13, and the side wall of the liquid cooling box body 10 for forming the drainage chamber 13 is provided with a diverter port 16 in an area away from the drainage port 15, and a confluence port 17 is provided in an area close to the drainage port 15, and both the diverter port 16 and the confluence port 17 are connected to the drainage pipe 50; the diverter plate 32 is vertically arranged in the drainage chamber 13, and is located between the diverter port 16 and the confluence port 17, so as to force the coolant located on the side of the diverter plate 32 away from the drainage port 15 to enter the confluence port 17.

[0100] In this way, by setting a drainage pipe 50 parallel to the drainage chamber 13 on the outside of the liquid cooling box 10 and setting a diverter plate 32 in the drainage chamber 13, the drainage chamber 13 can be divided into two parts, front and rear, so that the coolant in the front area close to the drainage port 15 is directly discharged from the drainage port 15, while the coolant in the rear area cannot flow directly to the drainage port 15 due to the obstruction of the diverter plate 32, and can only pass through the diverter port 16, the drainage pipe 50 and the confluence port 17 in sequence to enter the front area close to the drainage port 15, thereby accelerating the flow rate of the coolant in the area far from the drainage port 15 in the drainage chamber 13, so that the discharge of the coolant is smoother.

[0101] The number of the diverter plates 32 is not specifically limited, and may be one or more than two. Figure 4 As shown, when the number of the diverter plates 32 is at least two, the diverter plates 32 are spaced apart along the length direction of the partition plate 30, and diverter ports 16 are also distributed between two adjacent diverter plates 32, thereby ensuring that the coolant entering the drain chamber 13 from each overflow port 31 in the rear area of ​​the liquid cooling chamber 12 can quickly converge to the drain port 15.

[0102] Specific, combined Figure 1 , Figure 6 and Figure 7The liquid cooling box 10 has M diversion openings 16 on the side of a diversion plate 32 farthest from the drain port 15, and N diversion openings 16 between two adjacent diversion plates 32, wherein M is an integer greater than or equal to 2, N is an integer greater than or equal to 1, and M>N. In this way, the speed at which the coolant in the area far from the drain port 15 in the drain cavity 13 converges to the drain port 15 can be further accelerated.

[0103] In this embodiment, one side of the diverter plate 32 is connected to the inner side wall of the diverter port 16, and the other side is connected to the partition plate 30, so as to facilitate the connection and fixation of the diverter plate 32. Specifically, the diverter plate 32 is integrally connected to the liquid cooling box 10 to ensure the connection strength, and can also be connected by welding or other methods. There can be no gaps between the partition plate 30 and the inner side wall and the bottom wall of the liquid cooling box 10, or there can be gaps.

[0104] In addition, in the drainage cavity 13, a plurality of reinforcement members 33 are connected between the top of the partition plate 30 and the side wall of the liquid cooling box 10, and the reinforcement members 33 are spaced apart along the length direction of the partition plate 30, thereby improving the vertical fixation stability reliability of the partition plate 30.

[0105] Optionally, the liquid cooling box further includes a plurality of partitions 60, each of which is arranged in the liquid cooling chamber 12 at intervals along the length direction of the partition plate 30, and each of the partitions 60 is connected to the partition plate 30 and the inner wall of the liquid cooling box body 10 to divide the liquid cooling chamber 12 into a plurality of side-by-side liquid cooling zones 18;

[0106] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 An overflow groove 61 is provided on the top of the partition 60, and the overflow groove 61 is connected to the overflow port 31, and the overflow groove 61 is connected to the liquid cooling area 18 on both sides of the groove width direction.

[0107] In this way, by setting a plurality of partitions 60, the liquid cooling chamber 12 is divided into a plurality of liquid cooling zones 18 along the length direction, so that electronic hot spares with different power consumption can be placed in the liquid cooling zone 18, for example, a device with slightly higher heat generation is placed in some liquid cooling zones 18 close to the liquid inlet 14, and a device with slightly lower heat generation is placed in some liquid cooling zones 18 far from the liquid inlet 14, so as to meet the heat exchange requirements of different devices. Among them, since the overflow groove 61 is set in the partition 60, the coolant in the liquid cooling zone 18 can overflow from the liquid cooling zone 18 to the overflow groove 61 on both sides of the length direction of the liquid cooling chamber 12. Compared with the single-side overflow, the overflow groove 61 can increase the overflow area of ​​the coolant overflowing from the liquid cooling chamber 12 to the drainage chamber 13, so that the coolant can overflow into the drainage chamber 13 more smoothly.

[0108] The depth of the overflow groove 61 gradually increases along the direction from the end of the overflow groove 61 away from the partition plate 30 to the end connected to the overflow port 31, that is, along the groove length direction of the overflow groove 61. This can facilitate the coolant in the overflow groove 61 to flow into the drainage cavity 13 better, and such a setting can reduce the liquid difference, avoiding the splashing of the coolant falling from the overflow groove 61 to the leaching cavity and the generation of bubbles.

[0109] Optionally, the top edge of the partition plate 30 is flush with the top edge of the partition 60, thereby preventing the temperature of the electronic equipment near the drainage chamber 13 from being high due to the partition plate 30 being lower than the partition 60 and the overflow speed from being insufficient due to the partition plate 30 being higher than the partition 60, thereby comprehensively ensuring the heat dissipation effect and overflow speed of the electronic equipment near the drainage chamber 13 in the liquid cooling chamber 12. Of course, in some embodiments, the top edge of the partition plate 30 may also be higher or lower than the top edge of the partition 60.

[0110] The separator 60 also has a plurality of notches 62 distributed on both sides of the overflow groove 61 in the groove width direction. In this way, the coolant flows from the notches 62 in each liquid cooling zone 18 to the overflow groove 61, which can enhance heat dissipation, and the bubbles can flow toward the top surface and disappear better, thereby preventing the coolant from carrying more gas and accelerating the emulsification of the coolant, which affects the heat exchange efficiency and service life of the coolant.

[0111] Optionally, along the groove length direction of the overflow groove 61, the notches 62 on both sides of the overflow groove 61 are staggered, so that the coolant flowing out of the notches 62 on both sides can be prevented from colliding with each other, and the overflow groove 61 can be set narrower, so as to improve space utilization and reduce length. In this embodiment, the notch 62 is a through-hole structure that does not penetrate the top edge of the separator 60 to prevent the network cable from being stuck in the notch 62 and affecting the overflow effect, and the shape of the notch 62 is an inverted triangle. Setting the notch 62 as an inverted triangle can better break the surface tension of the coolant, so that the coolant can better overflow from the notch 62 into the overflow groove 61. In addition, the notch 62 can also be a groove-shaped structure that penetrates the top edge of the separator 60, in which case it can be triangular or fan-shaped, so that the top of the separator 60 appears serrated or wavy.

[0112] It should also be noted that, in some embodiments, the cold box also has a dispersion chamber 19 located between the liquid inlet chamber 11 and the liquid cooling chamber 12, the dispersion chamber 19 has a plurality of dispersion areas 190 that are not connected to each other, the liquid inlet chamber 11 is connected to each dispersion area 190 through a plurality of liquid inlet holes 21, and each dispersion area 190 is connected to a corresponding liquid cooling area 18 through a plurality of dispersion holes 193. In this way, by adding a layer of dispersion chamber 19 between the liquid inlet chamber 11 and the liquid cooling chamber 12, the diversion of the cooling liquid can be achieved, and the uniformity of the liquid inlet can also be ensured.

[0113] Moreover, electronic hot spares with different power consumption can be placed in the liquid cooling area 18. For example, devices with slightly higher heat generation can be placed in some liquid cooling areas 18 close to the liquid inlet 14, while devices with slightly lower heat generation can be placed in some liquid cooling areas 18 far from the liquid inlet 14, so as to meet the heat exchange requirements of different devices.

[0114] The dispersion cavity 19 can be formed in the following manner: Fig.10 A dispersion plate 191 is arranged on the upper side of the bottom plate 20 or the liquid inlet pipe assembly, and the dispersion plate 191 is connected to the inner wall of the liquid cooling box 10, so that a dispersion chamber 19 is formed between the dispersion plate 191 and the bottom plate 20 (or the liquid inlet pipe assembly), and the dispersion plate 191 and the inner wall of the liquid cooling box 10 are used as an immersion chamber. The bottom edge of the partition plate 30 is connected to the dispersion plate 191 to divide the immersion chamber into a liquid cooling chamber 12 and a drainage chamber 13. At the same time, a plurality of vertical plates 192 are arranged between the dispersion plate 191 and the bottom plate 20 (or the liquid inlet pipe assembly) and are distributed at intervals along the length direction of the liquid cooling box 10. In this way, the dispersion chamber 19 is divided into a plurality of dispersion areas 190 by the plurality of vertical plates 192, and a plurality of dispersion holes 193 are arranged on the dispersion plate 191 to realize the connection between each dispersion area 190 and a corresponding liquid cooling area 18.

[0115] In summary, the embodiment of the present application discloses a liquid cooling box and a container-type cooling system, wherein the internal space of the liquid cooling box body 10 is divided into a liquid inlet chamber 11 and an immersion chamber by a bottom plate 20, and the immersion chamber is divided into a liquid cooling chamber 12 and a liquid discharge chamber 13 by a partition plate 30. In this way, after a plurality of servers and other electronic equipment are densely arranged in the liquid cooling chamber 12, the cooling liquid delivered to the liquid inlet chamber 11 can be more evenly transmitted to various places in the liquid inlet chamber 11. Since a plurality of penetrating liquid inlet holes 21 are provided in the area corresponding to the liquid cooling chamber 12 on the bottom plate 20, when the cooling liquid at various places in the liquid inlet chamber 11 enters the liquid cooling chamber 12 from each liquid inlet hole 21, a plurality of cooling liquid jets with similar flow rates and velocities are formed due to the reduction in the flow area, thereby enabling servers and other electronic equipment at various positions in the liquid cooling chamber 12 to obtain more equal cooling liquid injection opportunities when working, so that the heat dissipation and cooling effects of various servers and other electronic equipment are close to the same, so as to reduce the risk of causing local servers to stop working due to high temperature. In addition, since the partition plate 30 is provided with a plurality of overflow ports 31 passing through the partition plate 30, the coolant in the liquid cooling chamber 12 can flow into the drain chamber 13 through the overflow port 31 in an overflow manner, and then be discharged through the drain port 15. In this way, the coolant in the liquid cooling chamber 12 can be smoothly discharged into the drain chamber 13, thereby ensuring the heat dissipation efficiency of the electronic equipment.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
