Description

Technical Field

[0001] This invention relates to the field of liquid cooling cabinet technology, and more specifically to a liquid cooling cabinet with a leak-proof device. Background Technology

[0002] In the current wave of technological development, new-generation digital technology applications, represented by AI big data models, continue to emerge, and the demand for computing power in various industries is showing an explosive growth trend. As the underlying support for computing power, data centers are also gradually evolving into intelligent computing centers, and the data center industry has thus ushered in a new round of technological innovation and development opportunities.

[0003] However, as data centers transform into intelligent computing centers, the increasing power of liquid-cooled server racks has led to increasingly stringent heat dissipation requirements, placing higher demands on the performance of cooling systems. Traditional cooling methods are no longer sufficient to meet the high-efficiency heat dissipation needs of core components such as CPUs and GPUs in high-power liquid-cooled server racks. Against this backdrop, data center cooling systems have officially entered the liquid cooling era. Liquid cooling technology, with its high-efficiency heat dissipation capabilities, has become a key technological direction for solving the heat dissipation problems of high-power liquid-cooled server racks.

[0004] In practical applications of liquid cooling systems, quick-connect fittings for liquid-cooled cabinet piping are crucial components for coolant transfer and connection / disconnection. However, most quick-connect fittings for liquid-cooled cabinet piping on the market currently suffer from a design flaw: the lack of any splash-proof measures. This design flaw causes coolant to splash out during insertion and removal of the quick-connect fitting. On one hand, this splashed coolant poses a risk of dripping onto surrounding electrical equipment, potentially causing malfunctions. On the other hand, the splashed coolant cannot be effectively collected, resulting in coolant waste and potentially affecting equipment performance and lifespan due to coolant residue or seepage, posing a serious threat to the stable operation of the data center.

Detailed Implementation

[0030] The present invention will be further described in conjunction with the following embodiments.

[0031] Depend on Figures 1 to 10 As can be seen, the liquid-cooled cabinet with a leak-proof device described in this embodiment includes a liquid-cooled cabinet body 6; the liquid-cooled cabinet body 6 is provided with a water manifold 1 and a plurality of cold plates 7; the cold plates 7 are connected to a first connector 71; the water manifold 1 is connected to a plurality of second connectors 11 that cooperate with the first connector 71; a leak-proof device is provided at the connection between the first connector 71 and the second connector 11.

[0032] The leak-proof device includes a leak-proof cover 2 and a drain head 3; the first connector 71 and the second connector 11 are disposed inside the leak-proof cover 2; one end of the leak-proof cover 2 is provided with a first opening 21; the other end of the leak-proof cover 2 is provided with a second opening 22; the leak-proof cover 2 is provided with a guide portion 23 between the first opening 21 and the second opening 22; the drain head 3 is disposed in the guide portion 23 and / or the second opening 22.

[0033] Specifically, in this embodiment, the liquid-cooled cabinet with a leak-proof device is used such that the first connector 71 of the cold plate 7 and the second connector 11 of the water manifold 1 are connected in the leak-proof cover 2. During the insertion and removal of the first connector 71 and the second connector 11, coolant will flow out and will flow through the guide part 23 to the drain head 3 for centralized discharge. This effectively prevents coolant spraying and enables effective water and electricity separation management of the liquid-cooled cabinet equipment system.

[0034] In this embodiment, the anti-leakage cover 2 uses a wrap-around design to shield the insertion and removal areas of the first connector 71 and the second connector 11, forming an anti-splash space to prevent coolant from splashing directly onto external electrical equipment; the guide section 23 guides the coolant flowing out when the first connector 71 and the second connector 11 are inserted and removed to converge towards the drain head 3, and the drain head 3 serves to concentrate and discharge the coolant to prevent coolant from accumulating inside the cover.

[0035] The liquid-cooled cabinet with a leak-proof device described in this embodiment includes a guide portion 23 comprising a plurality of sequentially connected protrusions 4. In this embodiment, the cross-sections of the protrusions 4, the first opening 21, and the second opening 22 are all circular; the cross-sections of the protrusions 4, the first opening 21, and the second opening 22 are concentrically arranged; the radius of the protrusions 4 gradually increases from the end near the first opening 21 to the end near the second opening 22.

[0036] Specifically, multiple sets of circular protrusions 4 form a stepped cavity, which can temporarily store the instantaneously splashed coolant and prevent the coolant from overflowing due to excessive splashing. The gradually changing radius design of the protrusions 4 utilizes gravity to allow the coolant to flow naturally towards the second opening 22 with a larger radius.

[0037] In this embodiment, a liquid-cooled cabinet with a leak-proof device is described. The radius of the first opening 21 is smaller than the radius of the protrusion 4 near one end of the first opening 21; the radius of the second opening 22 is larger than the radius of the protrusion 4 near one end of the second opening 22; the water distribution manifold 1 is located at the end of the leak-proof cover 2 near the first opening 21. Specifically, the radius difference between the first opening 21 and the first protrusion 4 forms a narrow inlet and wide outlet structure to prevent coolant backflow and leakage near the first opening 21; the radius difference between the second opening 22 and the last protrusion 4 forms a wide outlet and narrow outlet structure to prevent coolant from accumulating at the edge of the second opening 22 and ensure that all coolant flows into the drain head 3.

[0038] In addition, the circular cross-section and concentric design ensure that the inner wall of the leak-proof cover 2 has no sharp corners, preventing coolant from accumulating at the corners; in addition, the radius of the second opening 22 is larger, which provides sufficient operating space for the insertion and removal of the first connector 71, and forms an expanded-diameter channel with the guide part 23 to guide the coolant to flow towards the drain head 3.

[0039] This embodiment describes a liquid-cooled cabinet with a leak-proof device. The second connector 11 has a fixing part 12; the fixing part 12 is connected to the manifold 1; the first opening 21 is sleeved on the fixing part 12. The fixing part 12 is welded to the manifold 1; the first opening 21 and the fixing part 12 are connected by an interference fit. Specifically, the fixing part 12 is rigidly connected to the manifold 1 by welding to ensure the stability of the second connector 11 and prevent connector displacement due to vibration; in addition, the interference fit between the first opening 21 and the fixing part 12 utilizes the elastic deformation of the leak-proof cover 2 material (such as rubber or silicone) to fill the tiny gap between them, achieving a gapless seal.

[0040] In this embodiment, a liquid-cooled cabinet with a leak-proof device is described, wherein the drain head 3 is connected to a protrusion 4 near the second opening 22. Specifically, the protrusion 4 near the second opening 22 is the area where the coolant finally converges. The drain head 3 is directly connected to this position, which can shorten the coolant flow path and reduce flow resistance. At the same time, the coolant volume is most concentrated at this position, enabling rapid drainage and preventing the coolant from remaining in the leak-proof cover 2 for a long time.

[0041] The liquid-cooled cabinet with a leak-proof device described in this embodiment has flow-guiding slopes 5 between the first opening 21 and the protrusion 4, between the second opening 22 and the protrusion 4, and between two adjacent protrusions 4. Specifically, the flow-guiding slopes 5 guide the coolant to flow along the slope by tilting at an angle, avoiding dead zones formed at the connection points; at the same time, the slope structure can disperse the liquid impact force and prevent the liquid from splashing due to excessive flow velocity.

[0042] This embodiment describes a liquid-cooled cabinet with a leak-proof device. The bottom of the liquid-cooled cabinet is provided with a centralized drain tray 32; a drain pipe 31 connects the centralized drain tray 32 and the drain head 3. Specifically, multiple drain pipes 31 connect the drain heads 3 of multiple leak-proof devices to the centralized drain tray 32, so that all sprayed coolant is collected in the centralized drain tray 32 for unified processing.

[0043] The liquid-cooled cabinet with a leak-proof device described in this embodiment includes a connector 72 on the cold plate 7; a branch pipe 73 is provided between the connector 72 and the first connector 71. Specifically, the cold plate 7 is flexibly connected to the first connector 71 through the connector 72 and the branch pipe 73. The branch pipe 73 can adapt to the installation deviation between the cold plate 7 and the first connector 71, improving the installation flexibility.

[0044] This embodiment describes a liquid-cooled cabinet with a leak-proof device, wherein the liquid-cooled cabinet is equipped with a liquid-cooling distribution unit 8. Specifically, the liquid-cooling distribution unit 8 serves as a coolant control center, capable of adjusting the flow rate and pressure of the coolant to each second connector 11 as needed, adapting to the heat dissipation requirements of different cold plates 7.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
