Description

Liquid cooling piping structure and liquid cooling cabinet

[0001] This application claims priority to Chinese Patent Application No. 202411471963.X, filed on October 21, 2024, entitled "Liquid Cooling Piping Structure and Liquid Cooling Cabinet", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of liquid cooling technology, and in particular to a liquid cooling pipeline structure and a liquid cooling cabinet. Background Technology

[0003] With economic and social development, the demand for high-performance computing devices such as data center servers is increasing daily. These devices generate a lot of heat during operation, thus requiring liquid-cooled cabinets for heat dissipation.

[0004] 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 electrical devices. The other liquid-cooling piping structure can act as a collector, allowing coolant from each component to collect in the other liquid-cooling piping structure. Additionally, some designs include a blowout shield for the liquid-cooling piping structure. This shield covers the connection between the liquid-cooling piping structure and the liquid-cooling components to prevent leaked coolant from directly spraying onto the electrical devices.

[0005] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0006] The structure of the blowout preventer box can easily obstruct the connection between the liquid cooling piping and the liquid cooling components, making it difficult for users to visually inspect and maintain the connection. Summary of the Invention

[0007] In view of this, this application provides a liquid cooling pipeline structure and a liquid cooling cabinet, which can improve the problem in the prior art where the structure of the blowout preventer box obstructs the connection structure between the liquid cooling pipeline structure and the liquid cooling components, making it inconvenient for users to visually inspect and maintain the connection structure.

[0008] In a first aspect, this application provides a liquid cooling pipeline structure, which includes a main pipeline, at least two branch connectors, at least two guide pins, at least two anti-spray boxes, and at least two elastic members. The main pipeline is connected to the at least two branch connectors, and both the main pipeline and the branch connectors are used for circulating coolant. Each branch connector has at least a first interface and a second interface. The first interface is connected to the main pipeline, and the second interface is used for detachable connection to a corresponding liquid cooling component. The main pipeline is connected to the at least two guide pins, each guide pin passing through a corresponding anti-spray box, and each guide pin includes a limiting portion. The main pipe is elastically connected to the corresponding blowout preventer box via the elastic member, which is in a compressed state. The blowout preventer box can slide relative to the guide pin to a first position and a second position. In the first position, the elastic member presses the blowout preventer box against the limiting part, and the second interface of the branch connector is located inside the blowout preventer box. In the second position, the blowout preventer box is separated from the limiting part, and the second interface of the branch connector is located on the outside of the blowout preventer box on the side opposite to the main pipe.

[0009] As can be seen, the liquid cooling pipeline structure provided in this application can be used as a distributor or collector. The user can apply a force to the blowout preventer located at the first position to overcome the elastic force of the elastic element, so that the blowout preventer slides relative to the guide pin from the first position to the second position, so that the second interface of the branch connector is located outside the blowout preventer on the side away from the main pipeline. In other words, the second interface of the branch connector is exposed to the outside of the blowout preventer, so that the user can intuitively observe the position and structure of the second interface of the branch connector, which facilitates the user to quickly align and detachably connect the liquid cooling component with the second interface, and also allows the user to intuitively check whether the liquid cooling component and the second interface of the branch connector are installed in place.

[0010] After the second interface of the branch connector is connected to the liquid cooling component, the anti-spray box can slide relative to the guide pin from the second position to the first position. At this time, the connection structure between the second interface of the branch connector and the liquid cooling component is fitted by the corresponding anti-spray box. Even if coolant leakage occurs in the connection structure between the liquid cooling component and the second interface of the branch connector, the anti-spray box can block the leaked coolant, thereby reducing the possibility of the leaked coolant directly spraying onto the electrical components to be cooled, and thus reducing the possibility of the electrical components to be cooled malfunctioning.

[0011] During subsequent maintenance and routine inspections, users can also slide the anti-spray box relative to the guide pin from the first position to the second position, so that users can visually check whether there are any loosening or leakage problems in the connection structure between the second interface of the branch connector and the liquid cooling component. This allows users to maintain the connection structure between the second interface of the branch connector and the liquid cooling component more promptly, thereby further reducing the possibility of failure of the electrical components to be cooled.

[0012] In summary, using the liquid cooling pipeline structure provided in this application as a distributor or collector can improve the problem in the prior art where the structure of the anti-spray box obstructs the connection structure between the liquid cooling pipeline structure and the liquid cooling component, making it inconvenient for users to visually inspect and maintain the connection structure.

[0013] Optionally, the guide pin includes a first segment and a second segment connected to each other. The first segment is connected to the main pipe and passes through the blowout preventer box. The end of the first segment facing away from the main pipe is connected to the second segment. The diameter of the second segment is larger than the diameter of the first segment, so as to form a first step structure at the connection between the first segment and the second segment. The limiting part includes the first step structure.

[0015] Optionally, the blowout preventer box is further provided with a mating hole, at least in the first position, the second segment slides with the mating hole, and the second segment extends from the receiving cavity through the mating hole to the outside of the blowout preventer box on the side opposite to the main pipeline.

[0016] Optionally, the spray preventer box is provided with a stepped hole, which is penetrated by the first segment. The stepped hole includes a first hole and a second hole that are connected. The second hole is closer to the limiting part than the first hole, and the second hole is slidably engaged with the first segment. The diameter of the first hole is larger than the diameter of the second hole to form a second step structure between the first hole and the second hole. The first hole accommodates the end of the elastic member that is away from the main pipe, and the end of the elastic member that is away from the main pipe abuts against the second step structure.

[0019] Optionally, a portion of the structure of the first box and a portion of the structure of the second box are staggered along the length direction of the guide pin; one of the guide pins passes through both the first box and the second box, and the other guide pin passes through the second box.

Detailed Implementation

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] In the accompanying diagram, directions X, Y, and Z are perpendicular to each other, with direction Y being the vertical direction pointing from bottom to top.

[0044] Firstly, referring to Figure 1, this application embodiment provides a liquid cooling pipeline structure 10, which can be used as a distributor (water separator) or a collector (water collector). When the liquid cooling pipeline structure 10 is used as a distributor, it divides the coolant flowing into the liquid cooling pipeline structure 10 from the outside into multiple branches, so that different branches flow to different liquid cooling components (not shown in the figure). The liquid cooling components with coolant branches are used to cool corresponding heat-generating devices (e.g., servers, graphics processing units, GPUs, etc.). When the liquid cooling pipeline structure 10 is used as a collector, it collects the coolant flowing out of multiple liquid cooling components together, so that the coolant flowing out of multiple liquid cooling components is delivered to a heat exchanger together, so that the high-temperature coolant is converted into a low-temperature coolant.

[0045] Referring to Figure 2, the liquid cooling piping structure 10 includes a main pipe 1, branch connectors 2, guide pins 3, a blowout preventer 4, and a spring 5. At least two branch connectors 2 are connected to the main pipe 1, and at least two branch connectors 2 are spaced apart along the height direction (direction Y) of the main pipe 1. Referring to Figure 3, each branch connector 2 has at least a first interface (not shown in the figure) and a second interface 21. The first interface is connected to the main pipe 1, and the second interface 21 is used for detachable connection with the corresponding liquid cooling component (not shown in the figure).

[0046] Both the main pipe 1 and the branch connectors 2 are used for the flow of coolant. For example, external coolant first flows into the main pipe 1, and then the coolant is divided into at least two branches. Each branch flows to its corresponding branch connector 2, and the branch within each branch connector 2 then flows into the corresponding liquid-cooled component. The liquid-cooled component with the branch flowing through it then cools the corresponding heat-generating device (not shown in the figure). Alternatively, the branch within at least two liquid-cooled components can enter the main pipe 1 through at least two branch connectors 2 and then converge.

[0047] Referring to Figure 2, the main pipe 1 is connected to at least two guide pins 3, and the at least two guide pins 3 are spaced apart along the height direction (direction Y) of the main pipe 1. Each guide pin 3 passes through a corresponding blowout preventer box 4, and the guide pin 3 can restrict the movement of the blowout preventer box 4 in a direction perpendicular to direction X.

[0048] Referring to Figure 2, the main pipe 1 is also elastically connected to the corresponding blowout preventer box 4 through the elastic element 5, and the elastic element 5 is in a compressed state, that is, the elastic element 5 has accumulated elastic potential energy, and the elastic element 5 can apply elastic force to the blowout preventer box 4 in the direction X.

[0049] The blowout preventer cartridge 4 can slide relative to the guide pin 3 to the first position shown in Figures 3 and 4. When the blowout preventer cartridge 4 is in the first position, as shown in Figure 3, the second interface 21 is located inside the blowout preventer cartridge 4. As shown in Figure 5, the elastic member 5 presses the blowout preventer cartridge 4 against the limiting part 3a of the guide pin 3. At this time, the movement of the blowout preventer cartridge 4 relative to the guide pin 3 in the X direction is restricted when no external force is applied.

[0050] Of course, when an external force is applied to the blowout preventer box 4, the blowout preventer box 4 can also overcome the elastic force of the elastic element 5 and slide relative to the guide pin 3 to the second position shown in Figure 6. At this time, the second interface 21 is located outside the blowout preventer box 4 on the side away from the main pipeline 1, and the blowout preventer box 4 is separated from the limiting part 3a.

[0051] With the above-described structure, the user can apply a force in the opposite direction X to the blowout preventer 4 located in the first position to overcome the elastic force of the elastic element 5, so that the blowout preventer 4 slides relative to the guide pin 3 from the first position to the second position in the opposite direction X, so that the second interface 21 is located outside the blowout preventer 4 on the side opposite to the main pipe 1, that is, so that the second interface 21 is exposed to the outside of the blowout preventer 4, so that the user can intuitively observe the position and structure of the second interface 21, which makes it easy for the user to quickly align and detachably connect the liquid cooling component (not shown in the figure) with the second interface 21, and also makes it easy for the user to intuitively check whether the liquid cooling component (not shown in the figure) and the second interface 21 are installed in place.

[0052] After the second interface 21 is connected to the liquid cooling component, the user can apply a force along the X direction to the blowout preventer 4, or the user can cancel the application of force to the blowout preventer 4. The elastic element 5 will also release its elastic potential energy, causing it to apply an elastic force along the X direction to the blowout preventer 4. In short, the blowout preventer 4 can slide relative to the guide pin 3 from the second position to the first position along the X direction. At this time, the connection structure between the second interface 21 and the liquid cooling component is fitted with the corresponding blowout preventer 4. When coolant leakage occurs in the connection structure between the liquid cooling component and the second interface 21, the blowout preventer 4 can block the leaking coolant, reducing the possibility of the leaking coolant directly spraying onto the electrical components to be cooled, thereby reducing the possibility of the cooled electrical components malfunctioning.

[0053] It should be noted that regardless of whether the blowout preventer box 4 is in the first position or the second position, the elastic element 5 is in a compressed state, that is, the elastic element 5 always applies a force along the X direction to the blowout preventer box 4.

[0054] During subsequent maintenance and routine inspections, users can also slide the anti-spray box 4 relative to the guide pin 3 from the first position to the second position, so that users can visually check whether there are any loose or leaking problems in the connection structure between the second interface 21 and the liquid cooling component, so that users can maintain the connection structure between the second interface 21 and the liquid cooling component in a timely manner, thereby further reducing the possibility of failure of the electrical components to be cooled.

[0055] As can be seen from the above, using the liquid cooling pipeline structure 10 provided in this application as a distributor or collector can improve the problem in the prior art where the structure of the anti-spray box obstructs the connection structure between the liquid cooling pipeline structure and the liquid cooling component, making it inconvenient for users to visually inspect and maintain the connection structure.

[0056] It should be noted that the blowout preventer box 4 can be provided with two through holes arranged opposite each other in the X direction. The branch connector 2 can pass through one of the through holes to allow the branch connector 2 to extend from the main pipe 1 into the blowout preventer box 4. When the blowout preventer box 4 is in the second position, the branch connector 2 can also pass through the other through hole so that the second interface 21 is located on the outside of the blowout preventer box 4 on the side opposite to the main pipe 1. When the blowout preventer box 4 is in the first position, the branch connector 2 does not pass through the other through hole so that the second interface 21 is located inside the blowout preventer box 4. This article will introduce the two through holes for the branch connector 2 after introducing the structure of the guide pin 3.

[0057] It should be noted that the branch connector 2 can be a female head of a quick-release connector, meaning that the branch connector 2 is an insertable structure. Specifically, the branch connector 2 can be a female head of a blind-mating fluid connector. This configuration facilitates quick assembly or disassembly of the branch connector 2 and the liquid cooling component.

[0058] Optionally, referring to Figure 5, the guide pin 3 includes a first segment 31 and a second segment 32 connected together. The first segment 31 is connected to the main pipe 1 as shown in Figure 4, and the first segment 31 passes through the blowout preventer box 4. The end of the first segment 31 facing away from the main pipe 1 is connected to the second segment 32. The diameter of the second segment 32 is larger than the diameter of the first segment 31, so as to form a first step structure at the connection between the first segment 31 and the second segment 32. The limiting part 3a described above may include the first step structure, which can limit the slide of the blowout preventer box 4 located in the first position in the direction X.

[0059] It should be noted that both the first segment 31 and the second segment 32 can be cylindrical structures, which are easy to manufacture and assemble.

[0060] In other embodiments (not shown in the figures), the guide pin may also include a rod-shaped structure and a protruding structure, the protruding structure being formed by the rod-shaped structure protruding in a direction perpendicular to the length direction of the rod-shaped structure, the blowout preventer box being able to slide between a first position and a second position along the length direction of the rod-shaped structure, if the blowout preventer box is in the first position, the blowout preventer box is pressed against the protruding structure by an elastic member.

[0061] Optionally, referring to Figure 5, the blowout preventer 4 is provided with a receiving cavity 4c. A first section 31 extends from the outside of the blowout preventer 4 near the main pipe 1 into the receiving cavity 4c, and a limiting part 3a is located within the receiving cavity 4c. When the blowout preventer 4 is in the first position, the inner wall 4a of the blowout preventer 4 that forms the receiving cavity 4c abuts against the limiting part 3a. When the blowout preventer 4 is in the second position, the inner wall 4a of the blowout preventer 4 that forms the receiving cavity 4c separates from the limiting part 3a.

[0062] When the blowout preventer box 4 is in the first position, the second section 32 can extend from the receiving cavity 4c to the outside of the blowout preventer box 4 on the side opposite to the main pipeline 1. When the blowout preventer box 4 is in the second position, the entire structure of the second section 32 can be located outside the blowout preventer box 4 on the side opposite to the main pipeline 1.

[0063] In other embodiments (not shown in the figures), when the blowout preventer is in the first position, the entire structure of the second section can be located within the receiving cavity, and when the blowout preventer is in the second position, the second section can extend from within the receiving cavity to the outside of the blowout preventer on the side opposite to the main pipe.

[0064] In other embodiments (not shown in the figures), when the blowout preventer is in the first position, the entire structure of the second section can be located inside the receiving cavity, and when the blowout preventer is in the second position, the entire structure of the second section can be located outside the blowout preventer on the side of the blowout preventer away from the main pipe.

[0065] In other embodiments (not shown in the figures), the entire structure of the second segment can be located within the receiving cavity, regardless of whether the blowout preventer is in the first or second position.

[0066] In other embodiments (not shown in the figures), only the two structural walls of the first segment, which are arranged opposite each other along the length of the first segment, may be inserted through the first segment, while the entire structure of the second segment is located outside the side of the blowout preventer away from the main pipe. Correspondingly, the limiting part may be located outside the side of the blowout preventer away from the main pipe. When the blowout preventer is in the first position, the structural wall of the blowout preventer away from the main pipe abuts against the limiting part.

[0067] Optionally, the blowout preventer box 4 is also provided with a mating hole 41 as shown in Figure 7. When the blowout preventer box 4 is in the first position, the second segment 32 slides into the mating hole 41, and the second segment 32 extends from the receiving cavity 4c through the mating hole 41 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1. With this configuration, when the blowout preventer box 4 is in the first position, the guide pin 3 can restrict the movement of the blowout preventer box 4 in the Y direction not only through the first segment 31, but also through the second segment 32; similarly, the guide pin 3 can restrict the movement of the blowout preventer box 4 in the Z direction not only through the first segment 31, but also through the second segment 32; thus, the guide pin 3 can reliably restrict the rotation of the blowout preventer box 4 around the Z and X directions.

[0068] Among them, the mating hole 41 is located on the structural wall of the blowout preventer box 4 away from the main pipeline 1.

[0069] Furthermore, when the blowout preventer box 4 is in the second position, the mating hole 41 can slide to the position through which the first segment 31 passes. If the shaft hole fit between the blowout preventer box 4 and the guide pin 3 is a clearance fit, or if the clearance between the shaft hole between the blowout preventer box 4 and the guide pin 3 has a certain margin, allowing the blowout preventer box 4 in the second position to rotate slightly around the Z or Y direction, the structural wall in the blowout preventer box 4 used to enclose and form the mating hole 41 can also abut against the limiting part 3a. Under the elastic force of the elastic member 5 along the X direction, the structural wall in the blowout preventer box 4 used to enclose and form the mating hole 41 can also be pressed against the limiting part 3a, so that the blowout preventer box 4 is limited to the second position by the elastic member 5 and the limiting part 3a, or so that the blowout preventer box 4 is limited to the position between the second position and the first position by the elastic member 5 and the limiting part 3a. At this time, even if the user does not operate the blowout preventer box 4, the blowout preventer box 4 will not return to the first position, so as to ensure that the second interface 21 is exposed to the outside of the blowout preventer box 4. The user's hands can operate other structural components, so as to facilitate the user to perform installation, disassembly, inspection and maintenance operations, and the user's labor intensity is low.

[0070] In other embodiments (not shown in the figure), when the blowout preventer is in the second position, the blowout preventer can also be detachably connected to the main pipe by means of snap-fit, magnetic attraction, etc. The blowout preventer will not be reset to the first position, so as to ensure that the second interface of the branch connector is exposed to the outside of the blowout preventer, and the user's hands can operate other structural components, so as to facilitate the user to perform installation, disassembly, inspection and maintenance operations, and the user's labor intensity is low.

[0071] Optionally, referring to Figure 5, the blowout preventer box 4 is provided with a stepped hole 42, through which the first segment 31 passes. The stepped hole 42 includes a first hole 421 and a second hole 422 that are connected. The second hole 422 is closer to the limiting part 3a than the first hole 421. In other words, the first hole 421 is closer to the main pipe 1 than the second hole 422. The second hole 422 is in sliding fit with the first segment 31. The diameter of the first hole 421 is larger than the diameter of the second hole 422, so as to form a second step structure 423 between the first hole 421 and the second hole 422. The first hole 421 accommodates the end of the elastic member 5 facing away from the main pipe 1, and the end of the elastic member 5 facing away from the main pipe 1 abuts against the second step structure 423. With this arrangement, the first hole 421 can effectively restrict the movement of the end of the elastic member 5 facing away from the main pipe 1 in the Z and Y directions, so that the elastic member 5 can effectively apply a spring force in the X direction to the blowout preventer box 4.

[0072] The elastic element 5 may include a spring, which may be sleeved on the first segment 31 so that the spring can reliably extend and retract relative to the first segment 31 in the direction X, and so that the spring can reliably apply a spring force in the direction X to the blowout preventer box 4.

[0073] In other embodiments (not shown in the figure), the elastic element may not be fitted onto the first segment.

[0074] In other embodiments (not shown in the figures), the elastic element may also include elastic structural elements such as sheet springs and torsion springs.

[0075] In other embodiments (not shown in the figures), the end of the elastic member facing away from the main pipe may also abut against the outer structural wall of the blowout preventer box facing the main pipe.

[0076] In addition, the stepped hole 42 is recessed inward from the outer wall of the blowout preventer box 4. With this setting, the assembly structure between the guide pin 3, the blowout preventer box 4 and the elastic member 5 has a high degree of structural compactness, which makes the volume of the liquid cooling pipeline structure 10 smaller, thereby making the liquid cooling pipeline structure 10 occupy less internal space of the liquid cooling cabinet.

[0077] Optionally, referring to Figure 2, each blowout preventer box 4 corresponds to two guide pins 3 and two elastic members 5. The same blowout preventer box 4 includes a first box body 43 and a second box body 44 that are detachably connected. The first box body 43 is penetrated by one of the guide pins 3, and the first box body 43 is pressed against the limiting portion 3a of one of the guide pins 3 by one of the elastic members 5. The second box body 44 is penetrated by the other guide pin 3, and the second box body 44 is pressed against the limiting portion 3a of the other guide pin 3 by the other elastic member 5. With this configuration, both the first box body 43 and the second box body 44 can be installed on the main pipeline 1 via their corresponding guide pins 3, resulting in a high degree of reliability in the installation structure between the blowout preventer box 4 and the main pipeline 1.

[0078] The first housing 43 may be provided with the mating hole 41 and the stepped hole 42 described above, and the guide pin 3 passing through the first housing 43 passes through both the mating hole 41 and the stepped hole 42 located in the first housing 43. The second housing 44 may also be provided with the mating hole 41 and the stepped hole 42 described above, and the guide pin 3 passing through the second housing 44 passes through both the mating hole 41 and the stepped hole 42 located in the second housing 44.

[0079] In addition, the first box 43 and the second box 44 enclose and form the receiving cavity 4c described above.

[0080] In other embodiments (not shown in the figures), only the first housing may be pierced by the two guide pins, or only the second housing may be pierced by the two guide pins.

[0081] In other embodiments (not shown in the figures), the first and second housings may also be welded together.

[0082] In other embodiments (not shown in the figures), the blowout protector can also be integrally molded.

[0083] Optionally, as shown in Figure 2, a portion of the structure of the first housing 43 and a portion of the structure of the second housing 44 are staggered along the length direction (direction X) of the guide pin 3. One guide pin 3 can be inserted into both the first housing 43 and the second housing 44 simultaneously, while the other guide pin 3 is inserted only into the second housing 44.

[0084] Optionally, referring to Figure 8, the guide pin 3 includes a first end 311 and a second end 321 disposed opposite to each other along the length direction (direction X) of the guide pin 3, and a limiting part 3a is located between the first end 311 and the second end 321. The first end 311 is threadedly connected to the main pipe 1, and the second end 321 is provided with a notch 321a, which is used to cooperate with a screwdriver. That is, the user can use a screwdriver to drive the guide pin 3 to rotate around the direction X, so that the first end 311 is tightened to the main pipe 1 to fix the guide pin 3 to the main pipe 1, or loosen the first end 311 from the main pipe 1 to remove the guide pin 3 from the main pipe 1.

[0085] The notch 321a can be a straight notch, a cross-shaped notch, or an internal hexagonal hole.

[0086] In other embodiments (not shown in the figures), the second end may include an external hexagonal connector for engaging with a wrench. That is, the user can use the wrench to manually rotate the guide pin, thereby tightening the first end onto the main pipe to secure the guide pin to the main pipe, or loosening the first end onto the main pipe to remove the guide pin from the main pipe.

[0087] It should be noted that the first end 311 can belong to the first segment 31, and the second end 321 can belong to the second segment 32.

[0088] Optionally, the notch and the external hexagonal connector may coexist at the second end (not shown in the figure) so that the user can operate the guide pin with different tools.

[0089] Optionally, the main pipe 1 includes a main pipe body and at least two bases connected to each other. The main pipe body is used for the flow of coolant. The main pipe body is connected to the branch connectors. Each base is detachably connected to a corresponding guide pin 3. The base can also abut against the end of the elastic member 5 away from the blowout preventer box 4.

[0090] The main body can be welded to the base, snapped together, magnetically attached, or integrally formed.

[0091] In addition, the base may be provided with at least two threaded holes, each threaded hole being used for threaded connection with the corresponding guide pin 3.

[0092] Optionally, as shown in Figure 9, the blowout preventer box 4 is provided with a first through hole 45, which communicates with the receiving cavity 4c. When the blowout preventer box 4 is in the first position, the branch connector 2 can extend from the main pipe 1 through the first through hole 45 into the receiving cavity 4c.

[0093] The first box 43 and the second box 44 together form the first through hole 45.

[0094] Optionally, referring to Figure 10, the blowout preventer box 4 is provided with a second through hole 442, which communicates with the receiving cavity 4c. When the blowout preventer box 4 is in the second position, the branch connector 2 can extend from the main pipe 1 through the first through hole 45, the receiving cavity 4c, and the second through hole 442 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1, thereby exposing the second interface 21 of the branch connector 2 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1.

[0095] The second box 44 encloses and forms the second through hole 442.

[0096] Optionally, referring to Figure 11, the blowout preventer 4 further includes a first door 46 and a second door 47. Both the first door 46 and the second door 47 are movably connected (rotatably or slidably) to the first housing 43 and the second housing 44. When the blowout preventer 4 is in the first position and the second interface 21 is not connected to the liquid coolant, the second interface 21 is located inside the blowout preventer 4. Correspondingly, the first door 46 and the second door 47 can cover the second through hole 442, preventing coolant leaking from the second interface 21 from being sprayed out of the blowout preventer 4 through the second through hole 442. Before sliding the blowout preventer box 4 from the first position to the second position, the first door 46 and the second door 47 can be moved to the open position to connect the receiving cavity 4c with the second through hole 442. During the process of sliding the blowout preventer box 4 from the first position to the second position, the second interface 21 can be moved from the receiving cavity 4c through the second through hole 442 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1. After the second interface 21 is connected to the liquid cooling component, the first door 46 and the second door 47 are still in the open position, so that during the process of sliding the blowout preventer box 4 from the second position to the first position, the second interface 21 can be reset into the receiving cavity 4c. At the same time, the liquid cooling component connected to the second interface 21 can also enter the receiving cavity 4c through the second through hole 442, so that the connection structure between the second interface 21 and the liquid cooling component is located in the receiving cavity 4c.

[0097] In other embodiments (not shown in the figures), the spray shield may also include a soft film (also known as a soft membrane), at least one of the first and second boxes being connected to the soft film. In its natural state, the soft film is used to cover the second through hole. Under external force, the soft film can elastically deform, thereby allowing the receiving cavity to communicate with the second through hole.

[0098] Optionally, as shown in FIG11, the spray preventer box 4 further includes a first actuating part 48 and a second actuating part 49. The first actuating part 48 is connected to the first door 46, and the second actuating part 49 is connected to the second door 47. At least a portion of the structure of the first actuating part 48 and at least a portion of the structure of the second actuating part 49 are located outside the first box 43 and the second box 44, so that the user's hand can reliably actuate the first actuating part 48 and the second actuating part 49, thereby reliably changing the position of the first door 46 and the second door 47.

[0099] Optionally, the spray preventer box 4 further includes a first torsion spring (not shown) and a second torsion spring (not shown). The first door 46 is elastically connected to at least one of the first box 43 and the second box 44 via the first torsion spring, and the second door 47 is elastically connected to at least one of the first box 43 and the second box 44 via the second torsion spring. The first and second torsion springs are always in a state of accumulating elastic potential energy. That is, under the condition that no external force or obstruction is applied to the first door 46 and the second door 47, the elastic force of the first torsion spring can cause the first door 46 to naturally close to the second through hole 442, and the elastic force of the second torsion spring can cause the second door 47 to naturally close to the second through hole 442.

[0100] Based on the above, the installation process of the liquid cooling pipeline structure 10 and the liquid cooling component in this embodiment of the application is as follows:

[0101] When the second interface 21 of the branch connector 2 is not connected to the liquid cooler and the blowout preventer box 4 is in the first position, firstly, the user can move the first actuating part 48 and the second actuating part 49 to move the first door 46 and the second door 47, so that the receiving cavity 4c communicates with the second through hole 442. Then, the user's hand pushes the first actuating part 48 and the second actuating part 49 to move in the opposite direction X, so that the blowout preventer box 4 slides from the first position to the second position. During the sliding process, the receiving cavity 4c and the second through hole 442 remain connected, and the positions of the first door 46 and the second door 47 do not structurally interfere with the second interface 21, so that the second interface 21 can move from inside the receiving cavity 4c through the second through hole 442 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1. Next, the user can connect the liquid cooler to the second interface 21. Finally, the user returns the blowout preventer box 4 to the first position.

[0102] Based on the above, the disassembly process of the liquid cooling pipeline structure 10 and the liquid cooling component in this application embodiment is as follows:

[0103] When the second interface 21 of the branch connector 2 is connected to the liquid cooler and the blowout preventer box 4 is in the first position, firstly, the user can move the first actuating part 48 and the second actuating part 49 to move the first door 46 and the second door 47 so that the positions of the first door 46 and the second door 47 will not structurally interfere with the liquid cooler and the second interface 21 during subsequent sliding. Then, the user's hand pushes the first actuating part 48 and the second actuating part 49 to move in the opposite direction X, so that the blowout preventer box 4 slides from the first position to the second position, allowing the liquid cooler and the second interface 21 to move from the receiving cavity 4c through the second through hole 442 to the outside of the blowout preventer box 4 on the side opposite to the main pipe 1. Next, the user can detach the liquid cooler and the second interface 21. Finally, the user returns the blowout preventer box 4 to the first position and moves the first actuating part 48 and the second actuating part 49 to move the first door 46 and the second door 47 to a position that can cover the second through hole 442.

[0104] Optionally, referring to Figure 12, the liquid cooling piping structure 10 also includes a quick-connect fitting 6 and an exhaust valve 7. The top end of the main pipe 1 is detachably connected to the exhaust valve 7 via the quick-connect fitting 6. Before the liquid cooling piping structure 10 is installed into the cabinet body of the liquid-cooled cabinet, coolant needs to be injected into the main pipe 1 and the gas needs to be vented. The gas in the main pipe 1 can be vented to the outside of the liquid cooling piping structure 10 through the quick-connect fitting 6 and the exhaust valve 7. After the gas is vented, the exhaust valve 7 can be removed to reduce the volume of the liquid cooling piping structure 10. Accordingly, the space occupied by the liquid cooling piping structure 10 in the liquid-cooled cabinet is reduced, which can save internal space of the liquid-cooled cabinet.

[0105] Among them, the quick-connect pipe 6 can be adapted to exhaust valves of different structural types.

[0106] Optionally, from the perspective shown in Figure 13, and referring to Figure 14, the liquid cooling pipeline structure 10 also includes a drain pipe 8, which includes a main drain pipe 81 and at least two liquid receiving funnels 82, each of which corresponds to a blowout preventer box 4.

[0107] Referring to Figure 9, the anti-spray box 4 is equipped with a drain channel 441, which is connected to the receiving cavity 4c. When coolant leaks from the second port 21, the leaked coolant can flow out from the receiving cavity 4c through the drain channel 441. Referring to Figure 14, the coolant flowing out through the drain channel 441 falls into the corresponding receiving funnel 82 located below, and finally the leaked coolant enters the main drain pipe 81.

[0108] The exhaust pipe of the exhaust valve 7 can be connected to the top of the main exhaust pipe 81 so that the trace amount of liquid carried in the gas discharged by the exhaust valve 7 can be discharged into the main exhaust pipe 81.

[0109] In addition, the main pipe 81 can be connected to the side wall of the main pipe 1 by means of snap-fit, adhesive, hanging, magnetic attraction or fastening.

[0110] Optionally, as shown in Figure 15, the liquid cooling piping structure 10 also includes a liquid receiving tray 9, which is used to receive liquid discharged from the bottom of the main pipe 81. The liquid receiving tray 9 is also used to guide the liquid into the liquid accumulation tray at the bottom of the liquid cooling cabinet (not shown in the figure).

[0111] Optionally, as shown in Figure 15, the bottom of the main pipe 1 includes an inlet 11, through which external coolant can flow into the main pipe 1.

[0112] It should be noted that the liquid cooling pipeline structure described above can function as a distributor. The second interface of the branch connector of the liquid cooling pipeline structure can be connected to the inlet end of the liquid cooling component. The liquid cooling pipeline structure can divide the coolant into at least two branches, each of which can flow to its corresponding liquid cooling component. Alternatively, the liquid cooling pipeline structure described above can also function as a collector. The second interface of the branch connector of the liquid cooling pipeline structure can be connected to the outlet end of the liquid cooling component, allowing the branches within each liquid cooling component to converge within the liquid cooling pipeline structure.

[0113] Secondly, this application provides a liquid-cooled cabinet, which includes a cabinet body, a distributor, a collector, and at least two liquid-cooling components. The distributor, collector, and at least two liquid-cooling components are all detachably installed within the cabinet body. The distributor distributes coolant to each liquid-cooling component, and the collector collects coolant from each component. Both the distributor and collector employ the liquid-cooled piping structure 10 described above. Each liquid-cooling component has an inlet end and an outlet end. The inlet end is connected to the second interface of a branch connector of the distributor, and the outlet end is connected to the second interface of a branch connector of the collector. When the coolant outside the cabinet enters the distributor, the distributor divides the coolant into multiple streams. Each stream flows to its corresponding liquid cooling component. The streams within the liquid cooling component absorb heat from the corresponding heat-generating device. The streams within each liquid cooling component are then collected by the collector, which directs the coolant to the outside of the cabinet. The coolant dissipates heat on the outside of the cabinet and then flows back to the distributor, thus realizing the heat dissipation cycle described above.

[0114] The distributor and collector can be installed alternately, which makes it convenient for users to check and maintain the connection structure between the distributor and the liquid cooling component separately, and also makes it convenient for users to check and maintain the connection structure between the collector and the liquid cooling component separately.

[0115] In addition, the structure of the separator and the structure of the collector can be set symmetrically.

[0116] In other embodiments, the dispenser and the collector can be detachably connected.

[0117] In other embodiments, the dispenser and the collector may be different modules within the same device.

[0118] It should be noted that both the inlet and outlet ends can be male quick-release connectors, meaning they are the second interface for inserting into the branch connector. Specifically, both the inlet and outlet ends can be male blind-mating fluid connectors. This configuration facilitates quick assembly or disassembly of the branch connector and liquid cooling components.

[0119] 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.
