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

[0004] Traditional data center cooling systems rely primarily on air cooling, resulting in low energy efficiency. Immersive single-phase liquid cooling significantly improves cooling efficiency and reduces energy consumption. Immersive liquid cooling involves immersing servers in a chamber filled with an insulating coolant (such as transformer oil), which then removes heat through the flow of the coolant.

[0005] However, the drain port of the current 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 poor discharge affects the heat dissipation efficiency of the electronic equipment. Utility Model Content

[0012] The diverter plate is vertically arranged in the drainage cavity and located between the diverter port and the confluence port, so as to force the coolant located on the side of the diverter plate away from the drainage port to enter the confluence port.

[0013] In an optional embodiment, the number of the diverter plates is at least two, and the diverter plates are spaced apart along the length direction of the partition plate, and the diverter ports are also distributed between two adjacent diverter plates.

[0033] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0034] 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.

[0035] refer to Figures 1 to 3The liquid cooling box includes a liquid cooling box body 10 and a partition plate 20. The partition plate 20 is arranged in the internal space of the liquid cooling box body 10 and is connected to the bottom wall and / or side wall of the liquid cooling box body 10 to divide the internal space of the liquid cooling box body 10 into a liquid cooling chamber 11 and a drainage chamber 12. The partition plate 20 is provided with a plurality of overflow ports 21 passing through the partition plate 20. Each overflow port 21 is arranged along the length direction of the partition plate 20. A drainage port 13 is provided on the side wall of the liquid cooling box body 10 in an area corresponding to the drainage chamber 12.

[0036] In this way, a vertical partition plate 20 is set in the internal space of the liquid-cooling box 10, and the internal space of the liquid-cooling box 10 is divided into a liquid cooling chamber 11 and a drainage chamber 12 by the partition plate 20. In this way, the electronic equipment can be placed in the liquid cooling chamber 11, so that the heat of the electronic equipment during operation can be taken away by the coolant flowing into the liquid cooling chamber 11. Since the partition plate 20 is provided with a plurality of overflow ports 21 passing through, and each overflow port 21 is arranged along the length direction of the partition plate 20, the coolant in the liquid cooling chamber 11 can flow into the drainage chamber 12 in an overflow manner through the overflow port 21, and then be discharged through the drain port 13 after being collected in the drainage chamber 12. In this way, the coolant in the liquid cooling chamber 11 can be discharged smoothly into the drainage chamber 12, thereby ensuring the heat dissipation efficiency of the electronic equipment.

[0037] The liquid cooling box 10 is generally rectangular, which may be elongated as shown or square. The partition plate 20 may be vertically arranged within the interior of the liquid cooling box 10, with the length of the partition plate 20 aligned with the length of the liquid cooling box 10 and the thickness of the partition plate 20 aligned with the width of the liquid cooling box 10. This allows the liquid cooling chamber 11 and the drainage chamber 12 to be arranged horizontally side by side.

[0038] Of course, in other embodiments, the shape of the liquid cooling box 10 is not limited to a rectangle, and may be an ellipse, for example.

[0039] In this embodiment, the drain port 13 is located on at least one side of the drain cavity 12 in the length direction. Since the area closer to the drain port 13 in the drain cavity 12 gathers more coolant, in this embodiment, the depth of the drain cavity 12 gradually increases from the side close to the drain port 13 to the side away from the drain port 13, so that the coolant can be better accommodated.

[0040] In order to achieve a gradual depth change of the drainage cavity 12, the bottom wall of the liquid cooling box 10 used to form the drainage cavity 12 can be set into a sloped structure. Alternatively, a concave drainage groove can be directly set on the bottom wall of the liquid cooling box 10, and the depth of the drainage groove increases along the length of the drainage cavity 12, closer to the drainage port 13.

[0041] In addition, in other embodiments, the partition plate 20 may be tilted to make the drainage cavity 12 wider near the drainage port 13 , thereby improving the problem of high flow pressure of the coolant near the drainage port 13 .

[0042] In the illustrated embodiment, there is only one drainage port 13 located at one side of the drainage cavity 12 in the length direction. There is only one partition plate 20 , and therefore there is only one drainage cavity 12 .

[0043] Of course, two or more drain ports 13 may also be provided; for example, two drain ports 13 are respectively located on both sides of the drain cavity 12 in the length direction, that is, drain ports 13 are provided at both ends of the length direction of the liquid cooling box 10, and the depth of the drain cavity 12 gradually increases from the middle to the two ends, and the drain pipe 30 may be correspondingly cancelled. If there are more than three drain ports 13, then at least one additional drain port 13 may be provided on one side of the liquid cooling box 10 in the width direction, that is, on one side of the width direction of the drain cavity 12.

[0044] In addition, the drainage ports 13 may be provided only on both sides of the drainage chamber 12 in the width direction.

[0045] In other embodiments, the number of the partition plates 20 may also be two, so that the two partition plates 20 divide the internal space of the liquid cooling box 10 into a central liquid cooling chamber 11 and drainage chambers 12 located on both sides of the liquid cooling chamber 11 in the width direction.

[0046] In this embodiment, the bottom of the liquid cooling box 10 has a liquid inlet box, and a plurality of liquid inlet holes 16 are provided on the bottom wall of the liquid cooling box 10. The liquid inlet cavity in the liquid inlet box is connected with the liquid cooling cavity 11 through the liquid inlet holes 16. In order to adapt to the structure of the coolant entering the bottom of the liquid cooling cavity 11, the overflow port 21 is located at the upper part of the partition plate 20 and extends to the top edge of the partition plate 20, that is, extends to the side of the partition plate 20 away from the bottom wall of the liquid cooling box 10. In this way, after the coolant enters, it needs to flow upward for a distance before it can flow from the overflow port 21 to the drain cavity 12, so as to ensure that the coolant can pass a longer distance in the liquid cooling cavity 11 and better contact with the electronic equipment to take away heat.

[0047] The overflow port 21 may be a notch structure or a through-hole structure.

[0048] In this embodiment, since there is only one drain port 13, and since the drain cavity 12 is elongated and the drain port 13 is located on one side of the length direction of the drain cavity 12, the coolant flow rate in the area closer to the drain port 13 in the drain cavity 12 is faster, and the coolant flow rate in the area farther away from the drain port 13 is slower, which will cause the liquid level in the drain cavity 12 away from the drain port 13 to be level with the liquid cooling cavity 11, causing the liquid flow to be chaotic and affecting the heat dissipation effect. In order to improve this problem, in this embodiment, the liquid cooling box also includes a drain pipe 30 and a diverter plate 40. The drain pipe 30 is arranged on the outside of the side wall of the liquid cooling box body 10 for forming the drain cavity 12, that is, the drain pipe 30 is away from the liquid cooling cavity 11 relative to the drain cavity 12; the liquid cooling box body 10 is used to form a diverter port 14 on the side wall of the drain cavity 12 in an area away from the drain port 13, and a confluence port 15 is provided in an area close to the drain port 13, and the diverter port 14 and the confluence port 15 are both connected to the drain pipe 30; the diverter plate 40 is vertically arranged in the drain cavity 12, and is located between the diverter port 14 and the confluence port 15, so as to force the coolant located on the side of the diverter plate 40 away from the drain port 13 to enter the confluence port 15.

[0049] In this way, by arranging a drainage pipe 30 parallel to the drainage chamber 12 on the outside of the liquid cooling box 10 and arranging a partition plate 20 in the drainage chamber 12, the drainage chamber 12 can be divided into two parts, front and rear. In this way, the coolant in the front area near the drain port 13 is directly discharged from the drain port 13, while the coolant in the rear area cannot flow directly to the drain port 13 due to the obstruction of the partition plate 20, and can only pass through the diversion port 14, the drainage pipe 30 and the confluence port 15 in turn to enter the front area near the drain port 13, thereby accelerating the flow rate of the coolant in the area farther away from the drain port 13 in the drainage chamber 12, making the discharge of the coolant smoother.

[0050] There is no specific limit to the number of diverter plates 40, which can be one or more than two. When the number of diverter plates 40 is at least two, the diverter plates 40 are spaced apart along the length direction of the partition plate 20, and diverter ports 14 are also distributed between two adjacent diverter plates 40, thereby ensuring that the coolant entering the drain chamber 12 from each overflow port 21 in the rear area of the liquid cooling chamber 11 can be quickly gathered at the drain port 13.

[0051] Specifically, the liquid cooling box 10 has M diversion openings 14 on the side of the diversion plate 40 farthest from the drain port 13, and N diversion openings 14 between two adjacent diversion plates 40, where M is an integer greater than or equal to 2, N is an integer greater than or equal to 1, and M>N. This can further accelerate the speed at which coolant in the area of the drain chamber 12 that is too far from the drain port 13 converges to the drain port 13.

[0052] In this embodiment, one side of the manifold plate 40 is connected to the inner sidewall of the diversion port 14, and the other side is connected to the partition plate 20, facilitating the connection and fixation of the manifold plate 40. Specifically, the manifold plate 40 is integrally connected to the liquid cooling box 10 to ensure connection strength. Alternatively, welding, clamping, or other connection methods may be used. The partition plate 20 may be seamless or have a gap with the inner sidewall and bottom wall of the liquid cooling box 10.

[0053] In addition, in the drainage cavity 12, a plurality of reinforcements 50 are connected between the top of the partition plate 20 and the side wall of the liquid cooling box 10. The reinforcements 50 are spaced apart along the length direction of the partition plate 20, thereby improving the vertical fixation stability and reliability of the partition plate 20.

[0054] In summary, the embodiments of the present application disclose a liquid cooling box and a container-type cooling system, in which a partition plate 20 is provided in the internal space of the liquid cooling box body 10, and the internal space of the liquid cooling box body 10 is divided into a liquid cooling chamber 11 and a drainage chamber 12 by the partition plate 20. In this way, the electronic equipment can be placed in the liquid cooling chamber 11, so that the heat of the electronic equipment during operation can be taken away by the coolant in the liquid cooling chamber 11. Since the partition plate 20 is provided with a plurality of overflow ports 21 passing through, and each overflow port 21 is arranged along the length direction of the partition plate 20, the coolant in the liquid cooling chamber 11 can flow into the drainage chamber 12 in an overflow manner through the overflow port 21, and then be discharged through the drain port 13 after being collected in the drainage chamber 12. In this way, the coolant in the liquid cooling chamber 11 can be discharged smoothly into the drainage chamber 12, thereby ensuring the heat dissipation efficiency of the electronic equipment.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. 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 make equivalent replacements for some or all of the technical features therein.
