Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and in particular to a liquid spray shield, a liquid cooling pipeline structure, and a liquid cooling cabinet. Background Technology

[0002] With economic and social development, the demand for high-computing-power electronic devices such as mainframe computers and servers is increasing daily. These high-computing-power electronic devices generate a large amount of heat during operation, thus requiring liquid-cooled cabinets for heat dissipation.

[0003] In related technologies, a liquid-cooled cabinet includes two liquid-cooling piping structures and at least two liquid-cooling components. One liquid-cooling piping structure is connected to the at least two liquid-cooling components, and the at least two liquid-cooling components are connected to the other liquid-cooling piping structure. One of the liquid-cooling piping structures can act as a distributor, distributing coolant to each liquid-cooling component, which then cools different electronic devices. The other liquid-cooling piping structure can act as a collector, allowing the coolant from each component to collect in the other liquid-cooling piping structure. Additionally, some designs incorporate a blowout shield in the liquid-cooling piping structure. This shield covers the connection between the liquid-cooling piping structure and the liquid-cooling components, reducing the possibility of leaked liquid directly spraying onto the electronic devices.

[0004] In the process of realizing this invention, the inventors discovered at least the following problems in the related technology:

[0005] The liquid cooling piping structure is relatively large in volume and occupies a significant amount of internal space within the liquid cooling cabinet. Utility Model Content

[0006] This application provides a blowout preventer box, a liquid cooling pipeline structure, and a liquid cooling cabinet, which can improve the problem that the liquid cooling pipeline structure in the prior art occupies too much internal space in the liquid cooling cabinet.

[0007] In a first aspect, this application provides a blowout preventer box, which is provided with a communicating receiving cavity, a first through hole and a second through hole. The first through hole is for a branch connector of a liquid-cooled pipeline structure to pass through, and the second through hole is for a liquid-cooled connector of a liquid-cooled component to pass through. The receiving cavity is used to accommodate the connection structure between the branch connector and the liquid-cooled connector. The blowout preventer box also includes a liquid inlet structure and a liquid outlet structure. The liquid inlet structure is used for liquid located outside the blowout preventer box to enter the receiving cavity, and the liquid outlet structure is used for discharging liquid located inside the receiving cavity.

[0008] The connection structure between the branch connectors and liquid-cooling joints in the liquid-cooled piping structure is used for coolant flow. When the liquid-cooled piping structure acts as a distributor, coolant can flow from the liquid-cooled piping structure through the branch connectors and liquid-cooling joints to the liquid-cooled components. When the liquid-cooled piping structure acts as a collector, coolant can flow from the liquid-cooled components through the liquid-cooling joints and branch connectors to the liquid-cooled piping structure. Because the detachable connection structure between the branch connectors and liquid-cooling joints is located within a receiving cavity, when leakage occurs through this detachable connection structure, the leaked liquid can be effectively blocked within the blow-out preventer's receiving cavity, reducing the risk of leaked liquid directly spraying onto electronic equipment and thus lowering the risk of electronic equipment malfunction.

[0009] In a liquid cooling pipeline structure, if at least two blowout preventers are distributed along the height of the liquid cooling pipeline structure, the liquid in the containment cavity of the upper blowout preventer can fall through the drain structure of the upper blowout preventer to the inlet structure of the lower blowout preventer. The falling liquid then enters the containment cavity of the lower blowout preventer. The liquid in the containment cavity of the lower blowout preventer can fall through the drain structure of the lower blowout preventer to a lower blowout preventer or fall into the liquid recovery structure at the bottom of the liquid cooling pipeline structure.

[0010] Optionally, the liquid inlet structure is provided with a liquid inlet, the liquid outlet structure is provided with a liquid outlet, and the height of the liquid inlet is higher than the height of the liquid outlet; the projection range of the liquid outlet in the height direction of the blowout preventer box is within the range of the projection of the liquid inlet in the height direction.

[0011] Optionally, any section of the liquid inlet perpendicular to the height direction extends along the direction from the first through hole to the second through hole.

[0012] Optionally, the shape of any cross-section of the inlet perpendicular to the height direction includes a rectangle, an ellipse, or a trapezoid.

[0013] Optionally, the drain outlet is located on the bottom wall of the blowout preventer box; the area of ​​any cross-section of the drain outlet perpendicular to the height direction decreases along the direction from the top wall of the blowout preventer box to the bottom wall of the blowout preventer box.

[0014] Optionally, the shape of the drain outlet includes a frustum conical shape and / or a frustum pyramidal shape.

[0015] Optionally, the spray shield includes a first sidewall and a second sidewall spaced apart, the first sidewall having a first through hole and the second sidewall having a second through hole; the ratio of the distance between the drain outlet and the first sidewall to the distance between the drain outlet and the second sidewall is in the range of 0.8 to 1.2.

[0016] Optionally, the spray shield includes a first box and a second box, the first box and the second box being detachably connected; the liquid inlet structure is disposed in the first box, and the liquid outlet structure is disposed in the second box.

[0017] Secondly, this application provides a liquid cooling pipeline structure, the liquid cooling pipeline structure including at least two anti-spray boxes as described above; the at least two anti-spray boxes are distributed along the height direction of the liquid cooling pipeline structure; the drain structure of the anti-spray box located at the higher position is used to discharge liquid into the inlet structure of the anti-spray box located at the lower position.

[0018] Thirdly, this application provides a liquid-cooled cabinet, which includes a cabinet body, a liquid distributor, a liquid collector, and at least two liquid-cooling components. The liquid distributor, the liquid collector, and the at least two liquid-cooling components are all detachably installed in the cabinet body. The liquid distributor is detachably connected to the at least two liquid-cooling components, and the liquid collector is detachably connected to the at least two liquid-cooling components. Both the liquid distributor and the liquid collector adopt the liquid-cooled piping structure described above.

[0019] It can be seen that, compared with the prior art, the technical solution provided in this application has at least the following beneficial effects:

[0020] The blowout preventer provided in this application not only prevents leaked liquid from being directly sprayed onto electronic equipment, but also integrates a drainage function. Therefore, the liquid cooling piping structure equipped with the blowout preventer of this application does not require a drainage pipe, resulting in a relatively smaller liquid cooling piping structure and thus occupying less internal space in the liquid cooling cabinet. In summary, the use of the blowout preventer provided in this application in the liquid cooling piping structure can improve the problem of excessive internal space occupied by existing liquid cooling piping structures in the liquid cooling cabinet.

[0071] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0073] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0074] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0075] In a first aspect, embodiments of this application provide a liquid spray shield, which is a structural component of a liquid cooling pipeline structure.

[0076] Please refer to Figure 1As shown, the blowout preventer box 10 is provided with a first through hole 10a. Please refer to... Figure 2 As shown, the blowout preventer box 10 is provided with a second through hole 10b. Please refer to... Figure 1-Figure 2 As shown, the blowout preventer box 10 is also provided with a receiving cavity 10c, and the first through hole 10a, the receiving cavity 10c and the second through hole 10b are connected.

[0077] The first through hole 10a is for a branch connector (e.g., a male connector) of a liquid-cooled piping structure (not shown in the figure) to pass through, and the second through hole 10b is for a liquid-cooled connector (e.g., a female connector) of a liquid-cooled component (not shown in the figure) to pass through. The receiving cavity 10c is for accommodating the detachable connection structure between the branch connector and the liquid-cooled connector. It is understood that the above-mentioned branch connector and liquid-cooled connector are paired structural components, and quick connectors, especially blind-plug quick connectors, are generally selected.

[0078] It should be noted that in the attached figures of this article, directions X, Y and Z are perpendicular to each other. Direction Z represents the direction from the top of the blowout preventer box 10 to the bottom of the blowout preventer box 10. Direction Z can also be understood as the height direction of the blowout preventer box 10.

[0079] The connection structure between the branch connectors and the liquid-cooling joints is used for the flow of coolant. When the liquid-cooling piping structure acts as a distributor, coolant can flow from the liquid-cooling piping structure through the branch connectors and liquid-cooling joints to the liquid-cooled components. When the liquid-cooling piping structure acts as a collector, coolant can flow from the liquid-cooled components through the liquid-cooling joints and branch connectors to the liquid-cooling piping structure. The liquid-cooled components are used to cool electronic equipment (such as mainframe computers, servers, graphics processing units (GPUs), or central processing units (CPUs).

[0080] Since the detachable connection structure between the branch connector and the liquid cooling connector is located within the receiving cavity 10c, when leakage occurs in the detachable connection structure between the branch connector and the liquid cooling connector, the leaked liquid can be effectively blocked within the receiving cavity 10c by the blowout preventer, reducing the direct spraying of the leaked liquid onto the electronic equipment and thus reducing the risk of electronic equipment failure.

[0081] Please refer to Figure 1-Figure 2 As shown, the blowout preventer box 10 also includes a liquid inlet structure 11, please refer to... Figure 3 As shown, the blowout preventer box 10 also includes a drain structure 21. The inlet structure 11 is used for liquid located outside the blowout preventer box 10 to enter the receiving cavity 10c, and the drain structure 21 is used to discharge liquid located in the receiving cavity 10c.

[0082] It should be noted that the "liquid located outside the blowout preventer box 10" is liquid discharged by a drainage component in the liquid cooling piping structure. The drainage component in the liquid cooling piping structure may include at least one of the following: the blowout preventer box, the pressure relief pipe, and the vent pipe.

[0083] Taking a liquid cooling pipeline structure with a drainage function, including a blowout preventer, as an example, when the liquid cooling pipeline structure includes at least two such... Figure 4 When the blowout preventer boxes 10 are distributed in the height direction as shown. Figure 5 As shown, the liquid in the receiving cavity 10c of the upper blowout preventer 10 can fall through the drain structure 21 of the upper blowout preventer 10 to the inlet structure 11 of the lower blowout preventer 10. The falling liquid then enters the receiving cavity 10c of the lower blowout preventer 10. The liquid in the receiving cavity 10c of the lower blowout preventer 10 can fall through the drain structure 21 of the lower blowout preventer 10 to a lower blowout preventer (not shown in the figure) or fall into the collection tray (not shown in the figure) at the bottom of the liquid cooling pipeline structure.

[0084] In related technologies, liquid cooling piping structures require drain pipes to collect liquid discharged from each blowout preventer box. This necessitates the drain pipes extending along the height of the liquid cooling piping structure, resulting in a relatively large volume. On one hand, this leads to a relatively large liquid cooling piping structure, occupying more internal space within the liquid cooling cabinet, thus limiting the volume of electronic equipment that can be stored within the cabinet, or requiring a relatively large liquid cooling cabinet design. On the other hand, this also increases the structural complexity of the liquid cooling piping structure, making its manufacturing, assembly, and maintenance more difficult.

[0085] Compared to the aforementioned related technologies, the blowout preventer provided in this application not only prevents leaked liquid from being directly sprayed onto electronic devices, but also integrates the drainage function of the aforementioned drain pipe. Therefore, the liquid cooling pipeline structure with the blowout preventer of this application embodiment can eliminate the need for a drain pipe. This results in a relatively smaller liquid cooling pipeline structure, requiring less internal space in the liquid cooling cabinet, allowing for a larger volume of electronic equipment within the cabinet, or vice versa. Furthermore, it reduces the structural complexity of the liquid cooling pipeline structure, making its manufacturing, assembly, and maintenance relatively easier.

[0086] Taking a pressure relief pipe (not shown in the figure) as an example, a structural component in a liquid cooling pipeline structure that has a drainage function, when the internal liquid pressure of the liquid cooling pipeline structure is too high, the pressure relief pipe can discharge some liquid to reduce the internal liquid pressure of the liquid cooling pipeline structure, thereby reducing the possibility of liquid leakage. The liquid discharged by the pressure relief pipe can pass through... Figure 5 The liquid inlet structure 11 of the upper blowout preventer 10 shown enters the receiving cavity 10c of the blowout preventer 10, and the liquid in the receiving cavity 10c of the upper blowout preventer 10 is discharged into the lower blowout preventer 10 through the drain structure 21 of the upper blowout preventer 10.

[0087] Compared to related technologies where liquid cooling pipeline structures require the use of drain pipes to discharge the liquid discharged from pressure relief pipes, the anti-spray box structure of this application embodiment can reduce the volume and complexity of the liquid cooling pipeline structure. The specific effects have been described above and will not be repeated here.

[0088] In this case, there is no blowout preventer box 10 above the uppermost blowout preventer box 10. Therefore, the liquid discharged by the pressure relief pipe can enter the receiving cavity 10c of the uppermost blowout preventer box 10 through the liquid inlet structure 11 of the uppermost blowout preventer box 10.

[0089] Of course, in other embodiments, the liquid discharged by the pressure relief pipe may also enter the receiving cavity 10c of the non-topmost blowout preventer 10 via the liquid inlet structure 11 of the non-topmost blowout preventer 10.

[0090] Taking a liquid cooling pipeline structure with a drainage function, including an exhaust pipe, as an example, when gas is present inside the liquid cooling pipeline structure, the exhaust pipe can discharge the gas to improve liquid cooling efficiency. The gas discharged from the exhaust pipe may carry a small amount of liquid, and if the temperature of the discharged gas is lower than the surrounding air temperature, the discharged gas may also cause water vapor around the outlet of the exhaust pipe to condense into liquid. Therefore, the exhaust pipe also discharges liquid during the exhaust process. The liquid discharged from the exhaust pipe can be... Figure 5 The liquid inlet structure 11 of the upper blowout preventer 10 shown enters the receiving cavity 10c of the blowout preventer 10, and the liquid in the receiving cavity 10c of the upper blowout preventer 10 is discharged into the lower blowout preventer 10 through the drain structure 21 of the upper blowout preventer 10.

[0091] Compared to related technologies where liquid cooling pipeline structures require the use of drain pipes to discharge the liquid discharged from exhaust pipes, the anti-spray box structure of this application embodiment can reduce the volume and complexity of the liquid cooling pipeline structure. The specific effects have been described above and will not be repeated here.

[0092] The following content mainly describes the liquid inlet structure of the blowout preventer box for receiving the liquid discharged from the blowout preventer box located above.

[0093] In this case, there is no blowout preventer box 10 above the uppermost blowout preventer box 10. Therefore, the liquid discharged from the exhaust pipe can enter the receiving cavity 10c of the uppermost blowout preventer box 10 through the liquid inlet structure 11 of the uppermost blowout preventer box 10.

[0094] Of course, in other embodiments, the liquid discharged from the exhaust pipe may also enter the receiving cavity 10c of the non-topmost blowout preventer 10 via the liquid inlet structure 11 of the non-topmost blowout preventer 10.

[0095] It should be noted that the drain structure 21 of the bottommost blowout box 10 is used to drain the liquid into the collection tray (not shown in the figure) at the bottom of the liquid cooling pipeline structure or into other pipelines or containers for liquid recovery.

[0096] Alternatively, please refer to Figure 5 As shown, within the same blowout preventer box 10, the liquid inlet structure 11 is provided with a liquid inlet 11a, and the liquid outlet structure 21 is provided with a liquid outlet 21a. The height of the liquid inlet 11a is higher than the height of the liquid outlet 21a, and the projection range of the liquid outlet 21a in the height direction of the blowout preventer box 10 is within the projection range of the liquid inlet 11a in the height direction. Under this configuration, if the liquid cooling piping structure includes at least two... Figure 5 When the blowout preventer cartridges 10 are distributed in the height direction as shown, the liquid discharged from the drain port 21a of the upper blowout preventer cartridge 10 can accurately fall into the inlet port 11a of the lower blowout preventer cartridge 10, reducing the possibility of the liquid discharged from the upper blowout preventer cartridge 10 not falling into the lower blowout preventer cartridge 10, thereby enabling the cartridges to have at least two... Figure 5 The liquid cooling piping structure of the blowout preventer 10, distributed along the height direction, can reliably and effectively discharge liquid. Furthermore, within the same blowout preventer 10, the path along the height direction between the inlet 11a and the outlet 21a is relatively short, resulting in a relatively short residence time of falling liquid within the same blowout preventer 10. This allows for the reliable and efficient discharge of liquid. Figure 5 The liquid cooling piping structure of the blowout preventer 10, which is distributed in the height direction, can quickly drain liquid, reducing the risk of excessive liquid accumulation in the containment cavity 10c of any blowout preventer 10, thereby reducing the risk of liquid leakage from other non-drainage hole structures of the blowout preventer 10.

[0097] In other embodiments (not shown in the figures), based on the premise that "the range of the projection of the drain port in the height direction is within the range of the projection of the inlet port in the height direction," at least one of the inlet structure and the drain structure may have a retractable structure. If the inlet structure has a retractable structure, the inlet structure of the lower blowout preventer can extend towards the drain structure of the upper blowout preventer, so that the inlet of the lower blowout preventer is closer to the drain port of the upper blowout preventer, improving the accuracy of the liquid discharged from the upper blowout preventer falling into the lower blowout preventer. If the drain structure has a retractable structure, the drain structure of the upper blowout preventer can extend towards the inlet structure of the lower blowout preventer, so that the drain port of the upper blowout preventer is closer to the inlet of the lower blowout preventer, improving the accuracy of the liquid discharged from the upper blowout preventer falling into the lower blowout preventer.

[0098] In other embodiments, please refer to Figure 6 As shown, within the same blowout preventer 10, the projection range of the drain port 21a in the height direction may not be within the projection range of the inlet port 11a in the height direction. Accordingly, the liquid cooling piping structure needs to include at least two... Figure 6 The blowout preventer cartridges 10 shown have different structures and are distributed in the height direction. However, the projection range of the drain port 21a of the upper blowout preventer cartridge 10 in the height direction must be within the projection range of the inlet port 11a of the lower blowout preventer cartridge 10 in the height direction. With this arrangement, on the one hand, the liquid discharged from the drain port 21a of the upper blowout preventer cartridge 10 can accurately fall into the inlet port 11a of the lower blowout preventer cartridge 10, reducing the possibility of the liquid discharged from the upper blowout preventer cartridge 10 not falling into the lower blowout preventer cartridge 10, thereby enabling the cartridges to have at least two... Figure 6 The liquid cooling piping structure of the blowout preventers 10 with different structures distributed in the height direction can reliably and effectively discharge liquid. On the other hand, as the liquid discharged from the upper blowout preventer 10 falls into the lower blowout preventer 10, the falling liquid is buffered by the structural wall of the lower blowout preventer 10 to reduce the falling speed of the liquid. This reduces the speed of the liquid when it falls into the liquid collection tray at the bottom of the liquid cooling piping structure, thereby reducing the risk of liquid with excessive kinetic energy splashing from the liquid collection tray to other locations not used for liquid collection. This allows the liquid collection tray to reliably collect the liquid.

[0099] In other embodiments (not shown in the figures), at least one of the inlet and outlet structures may have a flexible structure, which may include a hose. If the inlet structure includes a hose, the hose of the inlet structure of the lower blowout preventer can be connected to the outlet structure of the upper blowout preventer, for example, the hose is fitted onto the outlet structure. If the outlet structure includes a hose, the hose of the outlet structure of the upper blowout preventer can be connected to the inlet structure of the lower blowout preventer, for example, the hose is fitted onto the inlet structure. On the one hand, this improves the reliability of the liquid discharged from the upper blowout preventer falling into the lower blowout preventer; on the other hand, even if the blowout preventer moves relative to the branch connector, the hose itself can flexibly deform, so that the inlet and outlet structures remain reliably connected, and the liquid discharged from the upper blowout preventer can still reliably fall into the lower blowout preventer.

[0100] The following content will mainly focus on... Figure 5 The blowout preventer 10 is illustrated by the example shown where "within the same blowout preventer 10, the range of the projection of the drain port 21a in the height direction is within the range of the projection of the inlet port 11a in the height direction".

[0101] In some applications, the blowout preventer box needs to move relative to the branch connector, for example, to allow for movement of the blowout preventer box. Figure 4 Any of the blowout preventer boxes 10 shown is moved in direction X so that the connector in the branch connector used for connecting to the liquid-cooled component moves from inside the receiving cavity of the blowout preventer box 10 to outside the blowout preventer box 10, so that the operator can observe the connector in the branch connector used for connecting to the liquid-cooled component. In this application scenario, please refer to... Figure 1 As shown, any cross-section of the inlet 11a perpendicular to the height direction can extend along the direction from the first through hole 10a to the second through hole 10b (the opposite direction of direction X). Figure 4As shown, even if the lower blowout preventer cassette 10 moves, the projection range of the drain port 21a of the upper, stationary blowout preventer cassette 10 in the height direction is still within the projection range of the inlet port 11a of the lower, moved blowout preventer cassette 10 in the height direction. This ensures that the upper, stationary blowout preventer cassette 10 can still discharge liquid into the lower, moved drain port 10, reducing the possibility of liquid discharged from the upper, stationary blowout preventer cassette 10 not falling into the lower, moved blowout preventer cassette 10. Similarly, even if the upper blowout preventer cassette 10 moves, the liquid can still be discharged into the lower, moved drain port 10. When the spray box 10 moves, the projection range of the drain port 21a of the upper moved spray box 10 in the height direction is still within the projection range of the inlet 11a of the lower unmoved spray box 10 in the height direction. This allows the upper moved spray box 10 to discharge liquid into the lower unmoved discharge box 10, reducing the possibility of the liquid discharged by the upper moved spray box 10 not falling into the lower unmoved spray box 10. This enables the liquid cooling pipeline structure to discharge liquid reliably and effectively.

[0102] Please refer to Figure 7 As shown, the liquid inlet 11a can be located on the top wall 10d of the blowout preventer box 10, and the top wall 10d can be perpendicular to the height direction.

[0103] In other embodiments, please refer to Figures 8-9 As shown, the top wall 10d can have an acute or obtuse angle with the height direction; in other words, the top wall 10d is inclined relative to the height direction.

[0104] In other embodiments, please refer to Figure 10 As shown, the liquid inlet 11a can be located on the structural wall of the blowout preventer box 10 below the top wall 10d.

[0105] Alternatively, please refer to Figure 1 and Figure 5 As shown, the shape of any cross-section of the inlet 11a perpendicular to the height direction includes a rectangle.

[0106] The rectangle can be a right-angled rectangle, a right-angled rectangle with inverted corners, or a rounded rectangle with inverted corners.

[0107] In addition, the rectangular liquid inlet 11a has a larger dimension in the X direction than in the Y direction.

[0108] In other embodiments, the shape of any cross-section of the inlet 11a perpendicular to the height direction may also include, for example: Figure 11 The trapezoid shown or as Figure 12 The shape shown is an ellipse.

[0109] Regarding Figure 7 The liquid inlet 11a shown can be provided as a liquid inlet structure 11, which can also be at least part of the structure in the top wall 10d. The dimension of the liquid inlet 11a in the height direction can be equal to the dimension of the top wall 10d in the height direction.

[0110] In other embodiments, please refer to Figure 13 As shown, the liquid inlet structure 11 can also be a structure that protrudes relative to the top wall 10d, and the dimension of the liquid inlet 11a in the height direction can be larger than the dimension of the top wall 10d in the height direction.

[0111] In other embodiments, please refer to Figure 14 As shown, the liquid inlet structure 11 can be a structure that protrudes relative to the side wall of the blowout preventer box.

[0112] regardless Figures 7-14 The structural configuration of the liquid inlet structure 11 must meet the requirement that the liquid inlet structure 11 can receive liquid moving from top to bottom.

[0113] The following content will mainly focus on... Figure 1 The liquid inlet structure 11 and liquid inlet 11a shown are described as examples.

[0114] Alternatively, please refer to Figure 15 As shown, the drain port 21a is located on the bottom wall 10e of the blowout preventer 10. The area of ​​any cross-section of the drain port 21a perpendicular to the height direction decreases along the direction (direction Z) from the top wall 10d of the blowout preventer 10 to the bottom wall 10e of the blowout preventer 10. With this arrangement, when the drain port 21a discharges liquid downwards, it has the effect of converging the liquid, thereby reducing the possibility of the discharged liquid dispersing and improving the accuracy of the liquid falling into the inlet 11a of the blowout preventer 10 located below.

[0115] Alternatively, please refer to Figure 15 As shown, the shape of the drain outlet 21a includes a frustum conical shape.

[0116] In other embodiments (not shown in the figures), the shape of the drain port 21a may also include a frustum pyramid shape.

[0117] In other embodiments (not shown in the figure), the drain port 21a may also include two sections distributed vertically, one of which may be shaped like a frustum of a cone and the other may be shaped like a frustum of a pyramid.

[0118] The following content mainly describes the shape of the drain outlet 21a, including the frustum-shaped shape.

[0119] The outer curved wall of the drainage structure 21 is the same as or similar to the outer curved wall of the frustum.

[0120] In other embodiments, the drainage structure 21 and drainage port 21a disposed on the bottom wall 10e can be as follows: Figure 16 As shown or as Figure 17 As shown.

[0121] In other embodiments, please refer to Figure 18 As shown, the drainage structure 21 and the drainage port 21a can also be located at the junction of the bottom wall 10e and the side wall of the blowout preventer box.

[0122] The following content will mainly focus on Figure 15 The drainage structure 21 and drainage port 21a shown are used as examples for illustration.

[0123] Alternatively, please refer to Figure 19 As shown, the blowout preventer box 10 includes a first sidewall 10f and a second sidewall 10g spaced apart. The first sidewall 10f is provided with a first through hole 10a, and the second sidewall 10g is provided with a second through hole 10b. The ratio of the distance d1 between the drain port 21a and the first sidewall 10f to the distance d2 between the drain port 21a and the second sidewall 10g is in the range of 0.8 to 1.2. Specifically, the ratio of distance d1 to distance d2 can be 0.8, 0.9, 1, 1.1 or 1.2. When the ratio is less than 0.8, the drain port 21a is too close to the first sidewall 10f. When the blowout preventer box 10 moves relative to the branch connector in the X direction, at least part of the projection range of the drain port 21a of the moved blowout preventer box 10 in the height direction is likely to be outside the projection range of the inlet 11a of the lower, unmoved blowout preventer box 10 in the height direction, so that the liquid discharged from the drain port 21a of the moved blowout preventer box 10 is unlikely to fall into the lower, unmoved blowout preventer box 10. When the ratio is greater than 1.2, the drain port 21a is too close to the second sidewall 10g. When the blowout preventer box 10 moves relative to the branch connector in the X direction, at least a portion of the projection range of the drain port 21a of the upper, unmoved blowout preventer box 10 in the height direction is likely to be outside the projection range of the inlet 11a of the lower, moved blowout preventer box 10 in the height direction. This makes it difficult for the liquid discharged from the drain port 21a of the upper, unmoved blowout preventer box 10 to fall into the lower, moved blowout preventer box 10. Therefore, it is preferable for the ratio of distance d1 to distance d2 to be in the range of 0.8 to 1.2, so that the liquid discharged from the drain port 21a of the upper blowout preventer box 10 can easily fall into the lower blowout preventer box 10.

[0124] It should be noted that if the shape of the drain port 21a includes a frustum conical shape or a cylindrical shape, the axis of the drain port 21a can be used as the distance reference. That is, distance d1 is the distance between the axis of the drain port 21a and the first sidewall 10f, and distance d2 is the distance between the axis of the drain port 21a and the second sidewall 10g. Of course, the inner wall surface of the drain structure 21 used to enclose and form the drain port 21a can also be used as the distance reference. That is, distance d1 is the shortest distance between the inner wall surface of the drain structure 21 and the first sidewall 10f, and distance d2 is the shortest distance between the inner wall surface of the drain structure 21 and the second sidewall 10g.

[0125] Optionally, a first path is provided between the liquid inlet structure 11 and the liquid outlet structure 21, and a second path is provided between the first through hole 10a and the second through hole 10b. The first path and the second path each have a certain size in the X, Y, and Z directions, and the first path and the second path do not intersect. With this configuration, within the same blowout preventer 10, when liquid falls from the liquid inlet structure 11 to the liquid outlet structure 21, the movement of the liquid is less likely to be interfered with by the branch connector (not shown in the figure) passing through the first through hole 10a, thereby reducing the possibility that the liquid will be bounced off the branch connector during the fall and then splashed out of the blowout preventer 10 through the liquid inlet structure 11.

[0126] Optionally, the number of inlet structures 11 of the blowout preventer 10 can be one, two, three or more. The number of drain structures 21 of the blowout preventer 10 can be one, two, three or more.

[0127] Alternatively, please refer to Figure 20 As shown, the blowout protector box 10 includes a first box body 1 and a second box body 2, which are detachably connected. Please refer to... Figure 21 As shown, the liquid inlet structure 11 is located in the first housing 1. Please refer to... Figure 22 As shown, the drainage structure 21 is disposed in the second housing 2. With this arrangement, on the one hand, the first housing 1, equipped with different types (sizes, shapes) of inlet structures 11, and the second housing 2, equipped with different types (sizes, shapes) of drainage structures 21, can be assembled into spray-proof boxes 10 of different types (sizes, shapes) to meet different drainage performance requirements, such as higher drainage rate and better drainage reliability. On the other hand, the manufacturing and assembly difficulty of the spray-proof box 10 is relatively low.

[0128] Please refer to Figure 21 As shown, the first box 1 may include multiple snap fasteners 12, please refer to... Figure 22 As shown, the second housing 2 may include multiple locking holes 22. The first housing 1 and the second housing 2 are detachably connected by engaging the locking buckle 12 and the locking holes 22.

[0129] In other embodiments (not shown in the figures), the first housing may also include multiple snap holes, and the second housing may also include multiple snap fasteners. The snap fasteners and snap holes engage to allow the first and second housings to be detachably connected.

[0130] In other embodiments (not shown in the figures), the first box and the second box can be magnetically connected, or the first box and the second box can be adhesively bonded, or the first box and the second box can be connected by fasteners such as bolts or screws.

[0131] In addition, the first box 1 and the second box 2 can be enclosed to form a first through hole 10a, the second box 2 can be provided with a second through hole 10b, and the first box 1 and the second box 2 can be enclosed to form a receiving cavity 10c.

[0132] Alternatively, please refer to Figure 20 As shown, the blowout preventer box 10 also includes a first door 3 and a second door 4. The first door 3 includes a first cover 31 and a first actuating member 32 connected together, and the second door 4 includes a second cover 41 and a second actuating member 42 connected together. By actuating the first actuating member 32 and the second actuating member 42, the blowout preventer box 10 can be positioned as follows: Figure 20 The first state shown or as Figure 23 The second state shown is in the first state, in which the first cover 31 and the second cover 41 cover the second through hole 10b, and in the second state, the first cover 31 and the second cover 41 do not cover the second through hole 10b.

[0133] When the branch connector is not connected to the corresponding liquid cooling component, the blowout preventer box 10 can be in the first state. Even if the branch connector leaks liquid, the leaked liquid can be blocked in the blowout preventer box 10 by the first cover 31 and the second cover 41. The leaked liquid can be discharged to the blowout preventer box or collection tray located below through the drainage structure of the blowout preventer box 10, reducing the possibility that the leaked liquid will be sprayed directly to the electronic equipment through the second through hole 10b.

[0134] When the branch connector needs to be connected to the corresponding liquid cooling component, the blowout preventer box 10 can be in the second state, and the liquid cooling interface of the liquid cooling component can enter the receiving cavity 10c from the outside of the blowout preventer box 10 through the second through hole 10b, thereby connecting the branch connector and the liquid cooling component.

[0135] Please refer to Figure 22 As shown, the second housing 2 can be provided with two notches 23. One notch 23 is for the first actuating member 32 to pass through, and the other notch 23 is for the second actuating member 42 to pass through.

[0136] In addition, both the first cover 31 and the second cover 41 can be rotatably connected to the first box 1 and the second box 2.

[0137] Additionally, please refer to Figures 21-22 As shown, at least one of the first box 1 and the second box 2 may be provided with a guide pin hole 10h. The guide pin hole 10h is used for the guide pin of the liquid cooling pipeline structure to pass through, so that the blowout preventer box moves relative to the branch connector in a direction parallel to the X direction under the guidance of the guide pin.

[0138] Secondly, embodiments of this application provide a liquid cooling pipeline structure, which includes at least two blowout preventers as described above, distributed along the height direction of the liquid cooling pipeline structure. The drain structure of the higher-positioned blowout preventer is used to discharge liquid into the inlet structure of the lower-positioned blowout preventer. Compared to the liquid cooling pipeline structures in the aforementioned related technologies, in the liquid cooling pipeline structure of this application embodiment, the blowout preventer structure not only prevents leaked liquid from being directly sprayed onto electronic equipment, but also integrates the drain function of the drain pipe. Therefore, the liquid cooling pipeline structure in this embodiment of the application may not require a drain pipe (e.g., a drain pipe installed on the main pipeline of the liquid cooling pipeline structure). On the one hand, this makes the volume of the liquid cooling pipeline structure relatively small, thus requiring less internal space in the liquid cooling cabinet, allowing for a larger volume of electronic equipment that can be stored inside the liquid cooling cabinet, or the volume of the liquid cooling cabinet itself can be relatively small. On the other hand, this makes the structural complexity of the liquid cooling pipeline structure relatively low, thus reducing the difficulty of manufacturing, assembling, and maintaining the liquid cooling pipeline structure.

[0139] The liquid cooling pipeline structure of this application embodiment also includes the other technical effects of the blowout preventer box described above, which will not be repeated here.

[0140] Please refer to Figure 24 As shown, the liquid cooling piping structure may include a main pipe 20, at least two blowout preventers 10, at least two branch connectors 30, and at least two guide pins 40. The at least two blowout preventers 10 are distributed along the height direction (direction Z), the at least two branch connectors 30 are distributed along the height direction (direction Z), and the at least two guide pins 40 are distributed along the height direction.

[0141] Please refer to Figure 24 As shown, the main pipe 20 is connected to at least two branch connectors 30. Each branch connector 30 is used for detachable connection with the corresponding liquid cooling component. The connector in each branch connector 30 for connection with the liquid cooling component can be located in the corresponding blowout preventer box 10. The main pipe 20 is connected to at least two guide pins 40. Each blowout preventer box 10 is penetrated by the corresponding guide pin 40.

[0142] Both the main pipe 20 and the branch connectors 30 are used to circulate coolant. When the liquid cooling pipeline structure acts as a distributor, the main pipe 20 can distribute the coolant to each branch connector 30, and each branch connector 30 can then introduce the coolant branch into the corresponding liquid cooling component (not shown in the figure). When the liquid cooling pipeline structure acts as a collector, the main pipe 20 can collect the coolant branch in each liquid cooling component (not shown in the figure) through each branch connector 30.

[0143] Each blowout preventer cartridge 10 can slide relative to its corresponding guide pin 40 in a direction parallel to direction X, for example, in Figure 24 and Figure 25 In the middle, the blowout preventer box 10 can be located in such a way as Figure 24 The positions shown and as Figure 25 The position shown moves between the indicated positions, and when the blowout preventer box 10 in the middle slides to... Figure 25 When the position is shown, the connector in the branch connector 30 corresponding to the middle blowout preventer box 10 for connecting with the liquid cooling component (not shown in the figure) is located outside the blowout preventer box 10, so that the user can easily observe and operate the connector in the branch connector 30 for connecting with the liquid cooling component.

[0144] exist Figure 24 and Figure 25 Although the position of the middle blowout preventer box 10 has been changed, the drainage structure 21 of the upper blowout preventer box 10 can still drain liquid into the middle blowout preventer box 10, and the drainage structure 21 of the middle blowout preventer box 10 can also drain liquid into the lower blowout preventer box 10. The relevant principles and effects have been described above and will not be repeated here.

[0145] Thirdly, this application provides a liquid-cooled cabinet, which includes a cabinet body, a liquid distributor, a liquid collector, and at least two liquid cooling components. The liquid distributor, liquid collector, and at least two liquid cooling components are all detachably installed within the cabinet body. The liquid distributor and the liquid collector are detachably connected to the at least two liquid cooling components. Both the liquid distributor and the liquid collector employ the liquid-cooled piping structure described above. Therefore, the liquid-cooled cabinet also includes the technical effects of the liquid-cooled piping structure described above, which will not be repeated here.

[0146] External coolant can flow into the liquid cooling component through the distributor. After absorbing the heat of the electronic equipment, the coolant in the liquid cooling component flows into the external circuit through the collector. After dissipating heat in the external circuit, the coolant flows back to the distributor, thus completing the required heat dissipation cycle.

[0147] The distributor can distribute coolant to at least two liquid cooling components, each of which is used to cool the corresponding electronic equipment. The collector is used to collect the tributaries of coolant from at least two liquid cooling components.

[0148] As can be seen from the above, the anti-spray box provided in the embodiments of this application can improve the problem that the liquid cooling pipeline structure occupies a lot of internal space in the liquid cooling cabinet in the prior art.

[0149] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
