Description

Technical Field

[0001] The present application relates to the field of liquid cooling technology, and in particular to a liquid cooling pipeline structure and a liquid cooling cabinet. Background Art

[0002] With the development of the economy and society, the demand for high-computing power electrical devices, such as data center servers, is increasing. These high-computing power electrical devices generate a lot of heat during operation, so liquid cooling cabinets are needed to dissipate the heat.

[0003] In the related art, a liquid-cooled cabinet includes two liquid-cooling pipe structures and at least two liquid-cooling components, wherein one liquid-cooling pipe structure is connected to at least two liquid-cooling components, which in turn are connected to another liquid-cooling pipe structure. One of the liquid-cooling pipe structures can function as a liquid separator, that is, one of the liquid-cooling pipe structures can divert the coolant to each liquid-cooling component, each of which is used to cool a different electrical component, while the other liquid-cooling pipe structure can function as a liquid collector, so that the coolant in each liquid-cooling component is then collected in the other liquid-cooling pipe structure. In addition, in some solutions, the liquid-cooling pipe structure is equipped with a liquid spray prevention box, which is used to cover the connection structure between the liquid-cooling pipe structure and the liquid-cooling component to prevent coolant leaking from the connection structure from directly spraying onto the electrical components.

[0004] In the process of realizing the present invention, the inventors discovered that the prior art has at least the following problems:

[0005] The structure of the liquid spray prevention box easily blocks the connection structure between the liquid cooling pipeline structure and the liquid cooling component, which makes it inconvenient for users to visually inspect and maintain the connection structure. Utility Model Content

[0006] In view of this, the present application provides a liquid cooling pipeline structure and a liquid cooling cabinet, which can improve the problem in the prior art that the structure of the anti-spray liquid box blocks the connection structure between the liquid cooling pipeline structure and the liquid cooling component, making it inconvenient for users to intuitively inspect and maintain the connection structure.

[0007] In a first aspect, the present application provides a liquid cooling pipeline structure, comprising a main pipe, at least two branch connectors, at least two guide pins, at least two spray prevention boxes, and at least two elastic members. The main pipe is connected to the at least two branch connectors, and both the main pipe and the branch connectors are used to circulate cooling liquid. Each branch connector has at least a first interface and a second interface, the first interface being connected to the main pipe, and the second interface being used for detachable connection to a corresponding liquid cooling component. The main pipe is connected to the at least two guide pins, each of which is inserted into a corresponding spray prevention box and includes a limit portion. The main pipe is elastically connected to the corresponding spray preventer liquid box via the elastic member, and the elastic member is in a compressed state. The spray preventer liquid 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 spray preventer liquid box against the limit portion, and the second interface of the branch connector is located inside the spray preventer liquid box. In the second position, the spray preventer liquid box is separated from the limit portion, and the second interface of the branch connector is located outside the spray preventer liquid box on a side facing away from the main pipe.

[0008] It can be seen that the liquid cooling pipeline structure provided in the present application can be used as a liquid separator or a liquid collector. The user can apply a force to the spray prevention liquid box located in the first position to overcome the elastic force of the elastic member, so that the spray prevention liquid box slides from the first position to the second position relative to the guide pin, so that the second interface of the branch connector is located outside the side of the spray prevention liquid box away from the main pipe, or in other words, so that the second interface of the branch connector is exposed to the outside of the spray prevention liquid box, so that the user can intuitively observe the position and structure of the second interface of the branch connector, so that the user can quickly align and detachably connect the liquid cooling part with the second interface, and also so that the user can intuitively check whether the liquid cooling part and the second interface of the branch connector are installed in place.

[0009] After the second interface of the branch connector is connected to the liquid cooling element, the spray prevention box can slide relative to the guide pin from the second position to the first position. At this point, the spray prevention box encases the connection structure between the second interface of the branch connector and the liquid cooling element. Even if coolant leaks from the connection structure between the liquid cooling element and the second interface of the branch connector, the spray prevention box can block the leaked coolant, reducing the possibility of the leaked coolant directly spraying onto the electrical component being cooled, thereby reducing the possibility of the electrical component malfunctioning.

[0010] During subsequent maintenance and daily inspections, the user can also slide the spray prevention box from the first position to the second position relative to the guide pin, so that the user can intuitively check whether the connection structure between the second interface of the branch connector and the liquid cooling component is loose or leaking, so that the user can 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 component to be cooled.

[0011] In summary, using the liquid cooling pipeline structure provided in the present application as a liquid separator or liquid collector can improve the problem in the prior art that the structure of the anti-spray box blocks the connection structure between the liquid cooling pipeline structure and the liquid cooling component, which makes it inconvenient for users to intuitively inspect and maintain the connection structure.

[0075] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0076] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0077] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0078] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0079] In the drawings herein, directions X, Y, and Z are perpendicular to each other, wherein direction Y is the height direction pointing from bottom to top.

[0080] First, please refer to Figure 1As shown, an embodiment of the present application provides a liquid cooling pipeline structure 10, which can be used as a liquid separator (water separator) or a liquid collector (water collector). When the liquid cooling pipeline structure 10 is used as a liquid separator, the liquid cooling pipeline structure 10 is used to divide the coolant flowing into the liquid cooling pipeline structure 10 from the outside into multiple tributaries, so that different tributaries flow to different liquid cooling parts (not shown in the figure), and the liquid cooling parts with coolant tributaries flowing therethrough are used to cool corresponding heat-generating devices (such as servers, graphics processing units GPUs and other electrical devices). When the liquid cooling pipeline structure 10 is used as a liquid collector, the liquid cooling pipeline structure 10 is used to collect the coolant flowing out of multiple liquid cooling parts together, so that the coolant flowing out of multiple liquid cooling parts is transported to the heat exchanger together, so that the high-temperature coolant is converted into a low-temperature coolant.

[0081] Please refer to Figure 2 As shown, the liquid cooling pipe structure 10 includes a main pipe 1, a branch connector 2, a guide pin 3, a spray prevention box 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. Figure 3 As shown, 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).

[0082] Both the main pipe 1 and the branch connector 2 are used to circulate coolant. For example, external coolant first flows into the main pipe 1, where it is then divided into at least two branches. Each branch flows to a corresponding branch connector 2. The branch within each branch connector 2 then flows into the interior of the corresponding liquid-cooling component. The liquid-cooling component with the branch flow then cools the corresponding heat-generating device (not shown in the figure). Of course, the branches within at least two liquid-cooling components can also pass through at least two branch connectors 2 and then converge into the main pipe 1.

[0083] Please refer to Figure 2 As shown, 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 is inserted into a corresponding spray-preventer box 4, and the guide pin 3 can limit the movement of the spray-preventer box 4 in a direction perpendicular to the direction X.

[0084] Please refer to Figure 2 As shown, the main pipe 1 is also elastically connected to the corresponding spray-proof liquid box 4 through an elastic member 5, and the elastic member 5 is in a compressed state, that is, the elastic member 5 accumulates elastic potential energy, and the elastic member 5 can apply an elastic force along the direction X to the spray-proof liquid box 4.

[0085] The spray-proof liquid box 4 can slide relative to the guide pin 3 to Figure 3 and Figure 4 When the spray-proof liquid box 4 is in the first position, as shown in FIG. Figure 3 As shown, the second interface 21 is located in the spray-proof liquid box 4. Figure 5 As shown, the elastic member 5 presses the spray-preventing liquid box 4 against the limiting portion 3a of the guide pin 3. At this time, under the condition that no external force is applied to the spray-preventing liquid box 4, the movement of the spray-preventing liquid box 4 relative to the guide pin 3 in the direction X is restricted.

[0086] Of course, under the condition that an external force is applied to the spray-proof liquid box 4, the spray-proof liquid box 4 can also overcome the elastic force of the elastic member 5 and slide relative to the guide pin 3 to the position as shown in FIG. Figure 6 In the second position shown, the second interface 21 is located outside the spray prevention liquid box 4 on a side facing away from the main pipe 1, and the spray prevention liquid box 4 is separated from the limiting portion 3a.

[0087] Under the above-mentioned structural setting, the user can apply a force in the direction opposite to the direction X to the spray liquid prevention box 4 located in the first position to overcome the elastic force of the elastic member 5, so that the spray liquid prevention box 4 slides from the first position to the second position in the direction opposite to the direction X relative to the guide pin 3, so that the second interface 21 is located outside the spray liquid prevention box 4 on the side facing away from the main pipe 1, that is, the second interface 21 is exposed to the outside of the spray liquid prevention box 4, so that the user can intuitively observe the position and structure of the second interface 21, facilitate the user to quickly align and detachably connect the liquid cooling component (not shown in the figure) with the second interface 21, and also facilitate the user to intuitively check whether the liquid cooling component (not shown in the figure) and the second interface 21 are properly installed.

[0088] After the second interface 21 is connected to the liquid cooling element, the user can apply a force in direction X to the spray prevention box 4. Alternatively, the user can remove the force applied to the spray prevention box 4. Naturally, the elastic member 5 will release its elastic potential energy, causing the elastic member 5 to continue applying a force in direction X to the spray prevention box 4. In short, the spray prevention box 4 can slide relative to the guide pin 3 from the second position in direction X to the first position. At this point, the connection structure between the second interface 21 and the liquid cooling element is encased by the spray prevention box 4. In the event of a coolant leak in the connection structure between the liquid cooling element and the second interface 21, the spray prevention box 4 can block the leaked coolant, reducing the possibility of the leaked coolant directly spraying onto the electrical components being cooled, thereby reducing the possibility of the components malfunctioning.

[0089] It should be noted that no matter the spray-proof liquid box 4 is in the first position or the second position, the elastic member 5 is in a compressed state, that is, the elastic member 5 always applies a force along the direction X to the spray-proof liquid box 4 .

[0090] During subsequent maintenance and daily inspections, the user can also slide the spray prevention box 4 from the first position to the second position relative to the guide pin 3, so that the user can intuitively check whether the connection structure between the second interface 21 and the liquid cooling component is loose or leaking, so that the user can promptly maintain the connection structure between the second interface 21 and the liquid cooling component, thereby further reducing the possibility of failure of the electrical components to be cooled.

[0091] From the above, it can be seen that using the liquid cooling pipe structure 10 provided in the present application as a liquid separator or a liquid collector can improve the problem in the prior art that the structure of the anti-spray box blocks the connection structure between the liquid cooling pipe structure and the liquid cooling component, which makes it inconvenient for users to intuitively inspect and maintain the connection structure.

[0092] It should be noted that the spray prevention liquid box 4 can be provided with two through-holes arranged opposite each other along the direction X. The branch connector 2 can be provided with one of the through-holes to facilitate the branch connector 2 to extend from the side of the main pipe 1 into the spray prevention liquid box 4. When the spray prevention liquid box 4 is in the second position, the branch connector 2 can also be provided with another through-hole to enable the second interface 21 to be located outside the spray prevention liquid box 4 on the side facing away from the main pipe 1. When the spray prevention liquid box 4 is in the first position, the branch connector 2 does not have the other through-hole, so that the second interface 21 is located inside the spray prevention liquid box 4. This article will introduce the two through-holes for the branch connector 2 to pass through after the structure of the guide pin 3.

[0093] It should be noted that the branch connector 2 can be a female connector for a quick-release connector, meaning that the branch connector 2 is designed to be inserted. Specifically, the branch connector 2 can be a female connector for a blind-mate fluid connector. This configuration facilitates quick assembly or disassembly of the branch connector 2 and the liquid-cooling unit.

[0094] Alternatively, see Figure 5 As shown, the guide pin 3 includes a first section 31 and a second section 32 connected to each other. Figure 4 The main pipe 1 is shown connected, with the first section 31 extending through the spray-preventing liquid box 4. The end of the first section 31 facing away from the main pipe 1 is connected to the second section 32. The diameter of the second section 32 is larger than that of the first section 31, forming a first step structure at the connection between the first section 31 and the second section 32. The stopper 3a described above may include the first step structure, which can function to limit the movement of the spray-preventing liquid box 4 in the first position along the direction X.

[0095] It should be noted that both the first section 31 and the second section 32 can be cylindrical structures, which are convenient for manufacturing and assembly.

[0096] In other embodiments (not shown in the figures), the guide pin may also include a rod-shaped structure and a protrusion structure, wherein the protrusion structure protrudes from the rod-shaped structure in a direction perpendicular to the length direction of the rod-shaped structure, and the spray preventer liquid box can slide between a first position and a second position along the length direction of the rod-shaped structure. When the spray preventer liquid box is in the first position, the spray preventer liquid box is pressed against the protrusion structure by the elastic member.

[0097] Alternatively, see Figure 5 As shown, the spray prevention liquid box 4 is provided with a accommodating chamber 4c. The first section 31 extends from the exterior of the spray prevention liquid box 4 on the side closest to the main pipe 1 into the accommodating chamber 4c, with the stopper 3a located within the accommodating chamber 4c. When the spray prevention liquid box 4 is in the first position, the inner wall 4a of the spray prevention liquid box 4, which encloses the accommodating chamber 4c, abuts the stopper 3a. When the spray prevention liquid box 4 is in the second position, the inner wall 4a of the spray prevention liquid box 4, which encloses the accommodating chamber 4c, separates from the stopper 3a.

[0098] When the spray preventer box 4 is in the first position, the second section 32 can extend from the accommodating chamber 4c to the outside of the spray preventer box 4 on the side facing away from the main pipe 1. When the spray preventer box 4 is in the second position, the entire structure of the second section 32 can be located outside of the side facing away from the main pipe 1.

[0099] In other embodiments (not shown), when the spray preventer liquid box is in the first position, the entire structure of the second section may be located within the accommodating chamber; and when the spray preventer liquid box is in the second position, the second section may extend from the accommodating chamber to the exterior of the spray preventer liquid box on a side facing away from the main pipe.

[0100] In other embodiments (not shown), when the spray preventer box is in the first position, the entire structure of the second section may be located within the accommodating chamber; and when the spray preventer box is in the second position, the entire structure of the second section may be located outside the spray preventer box on a side facing away from the main pipe.

[0101] In other embodiments (not shown in the figures), the entire structure of the second section can be located in the accommodating cavity regardless of whether the spray-proof liquid box is in the first position or the second position.

[0102] In other embodiments (not shown), only the first section may be provided through two structural walls of the spray preventer box that are arranged opposite each other along the length of the first section, while the entire structure of the second section is located outside the spray preventer box on the side facing away from the main pipe. Accordingly, the stopper may be located outside the spray preventer box on the side facing away from the main pipe. When the spray preventer box is in the first position, the structural wall of the spray preventer box facing away from the main pipe abuts the stopper.

[0103] Optionally, the spray-proof liquid box 4 is further provided with Figure 7The mating hole 41 is shown. When the spray preventer box 4 is in the first position, the second section 32 slidably engages with the mating hole 41 and extends from the accommodating chamber 4c through the mating hole 41 to the exterior of the spray preventer box 4 on the side facing away from the main pipe 1. Under this arrangement, when the spray preventer box 4 is in the first position, the guide pin 3 can not only restrict the movement of the spray preventer box 4 in direction Y via the first section 31, but also restrict the movement of the spray preventer box 4 in direction Y via the second section 32. Similarly, the guide pin 3 can not only restrict the movement of the spray preventer box 4 in direction Z via the first section 31, but also restrict the movement of the spray preventer box 4 in direction Z via the second section 32. Thus, the guide pin 3 can reliably restrict the rotation of the spray preventer box 4 in directions Z and X.

[0104] The matching hole 41 is located on the structural wall of the spray prevention liquid box 4 facing away from the main pipe 1 .

[0105] Furthermore, when the spray preventer box 4 is in the second position, the mating hole 41 can slide to a position penetrated by the first section 31. If the axial hole between the spray preventer box 4 and the guide pin 3 is a clearance fit, or if the clearance between the axial hole between the spray preventer box 4 and the guide pin 3 has a certain margin size, so that the spray preventer box 4 in the second position can rotate slightly around the direction Z or the direction Y, the structural wall of the spray preventer box 4 that encloses the mating hole 41 can also abut against the limiting portion 3a, and under the elastic force of the elastic member 5 in the direction X, the structural wall of the spray preventer box 4 that encloses the mating hole 41 can also be pressed against the limiting portion 3a, so that the spray preventer box 4 is limited in the second position by the elastic member 5 and the limiting portion 3a, or so that the spray preventer box 4 is limited in the second position by the elastic member 5 and the limiting portion 3a. At this time, even if the user's hands do not operate the spray preventer box 4, the spray preventer box 4 will not return to the first position, so as to ensure that the second interface 21 is in a position exposed to the outside of the spray preventer box 4. The user's hands can operate other structural parts, so that the user can perform operations such as installation, disassembly, inspection and maintenance, and the user's labor intensity is low.

[0106] In other embodiments (not shown in the figures), when the spray preventer box is in the second position, the spray preventer box can also be detachably connected to the main pipe by means of snap connection, magnetic attraction, etc., and the spray preventer box will not be reset to the first position, so as to ensure that the second interface of the branch connector is in a position exposed to the outside of the spray preventer box. The user's hands can operate other structural components, thereby facilitating the user's installation, removal, inspection, and maintenance operations, and reducing the user's labor intensity.

[0107] Alternatively, see Figure 5As shown, the spray-preventer box 4 is provided with a stepped hole 42, which is pierced by the first section 31. The stepped hole 42 includes a first hole 421 and a second hole 422 that are interconnected. The second hole 422 is closer to the stopper 3a than the first hole 421. Alternatively, the first hole 421 is closer to the main pipe 1 than the second hole 422. The second hole 422 slidably engages with the first section 31. The diameter of the first hole 421 is larger than the diameter of the second hole 422, forming a second step 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, which abuts against the second step 423. With this arrangement, the first hole 421 effectively limits the movement of the end of the elastic member 5 facing away from the main pipe 1 in directions Z and Y, thereby enabling the elastic member 5 to effectively exert a spring force in direction X on the spray-preventer box 4.

[0108] The elastic member 5 may include a spring, which may be sleeved on the first section 31 so that the spring can reliably expand and contract relative to the first section 31 along the direction X, and the spring can reliably apply an elastic force along the direction X to the spray-proof liquid box 4.

[0109] In other embodiments (not shown in the figures), the elastic member may not be sleeved on the first section.

[0110] In other embodiments (not shown in the figures), the elastic member may also include elastic structural members such as springs and torsion springs.

[0111] 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 spray-proof liquid box facing the main pipe.

[0112] In addition, the stepped hole 42 is recessed inward from the outer wall of the spray liquid prevention box 4. Under this arrangement, the assembly structure between the guide pin 3, the spray liquid prevention 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.

[0113] Alternatively, see Figure 2 As shown, the same spray prevention liquid box 4 corresponds to two guide pins 3 and two elastic members 5. The same spray prevention liquid box 4 includes a first box body 43 and a second box body 44 that are detachably connected. The first box body 43 is passed through one of the guide pins 3 and is pressed against the stopper 3a of one of the guide pins 3 by one of the elastic members 5. The second box body 44 is passed through the other guide pin 3 and is pressed against the stopper 3a of the other guide pin 3 by another elastic member 5. With this arrangement, both the first box body 43 and the second box body 44 can be mounted on the main pipe 1 via their corresponding guide pins 3, providing a highly reliable mounting structure between the spray prevention liquid box 4 and the main pipe 1.

[0114] The first box body 43 may be provided with the matching hole 41 and stepped hole 42 described above, and the guide pin 3 provided in the first box body 43 may also be provided with the matching hole 41 and stepped hole 42 located in the first box body 43. The second box body 44 may also be provided with the matching hole 41 and stepped hole 42 described above, and the guide pin 3 provided in the second box body 44 may also be provided with the matching hole 41 and stepped hole 42 located in the second box body 44.

[0115] In addition, the first box body 43 and the second box body 44 enclose and form the accommodating cavity 4c described above.

[0116] In other embodiments (not shown in the figures), only the first box body may be penetrated by two guide pins, or only the second box body may be penetrated by two guide pins.

[0117] In other embodiments (not shown in the figures), the first box body and the second box body may also be welded.

[0118] In other embodiments (not shown in the figures), the spray-proof liquid box may also be integrally formed.

[0119] Alternatively, see Figure 2 As shown, part of the structure of the first box body 43 and part of the structure of the second box body 44 are staggered along the length direction (direction X) of the guide pin 3. One of the guide pins 3 can be provided in both the first box body 43 and the second box body 44, while the other guide pin 3 is only provided in the second box body 44.

[0120] Alternatively, see Figure 8 As shown, the guide pin 3 includes a first end 311 and a second end 321 arranged opposite each other along the length direction (direction X) of the guide pin 3, with the stopper 3a 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. The notch 321a is adapted to engage with a screwdriver. That is, the user can use a screwdriver to rotate the guide pin 3 about the direction X, tightening the first end 311 to the main pipe 1 to securely mount the guide pin 3 to the main pipe 1, or loosening the first end 311 to remove the guide pin 3 from the main pipe 1.

[0121] The notch portion 321a may be a straight notch, a cross-shaped notch, or a hexagonal hole.

[0122] In other embodiments (not shown in the figures), the second end may include an external hexagonal connection portion, which is used to cooperate with a wrench, that is, the user can use a wrench to rotate the guide pin to tighten the first end to the main pipe to fix the guide pin to the main pipe, or loosen the first end to the main pipe to remove the guide pin from the main pipe.

[0123] It should be noted that the first end 311 may belong to the first section 31 , and the second end 321 may belong to the second section 32 .

[0124] Optionally, the notch portion and the external hexagonal connection portion may exist at the second end at the same time (not shown in the figure), so that the user can operate the guide pin with different tools.

[0125] Optionally, the main pipe 1 includes a main body and at least two connected bases. The main body is used to circulate the coolant and is connected to the branch connector. Each base is detachably connected to a corresponding guide pin 3, and the base can also abut against the end of the elastic member 5 facing away from the spray-proof liquid box 4.

[0126] The main body can be welded, clamped, magnetically attracted or integrally formed with the base.

[0127] In addition, the base may be provided with at least two threaded holes, each threaded hole being used for threaded connection with a corresponding guide pin 3 .

[0128] Alternatively, see Figure 9 As shown, the spray prevention liquid box 4 is provided with a first through hole 45, which is in communication with the accommodating chamber 4c. When the spray prevention liquid box 4 is in the first position, the branch connection member 2 can extend from the main pipe 1 through the first through hole 45 into the accommodating chamber 4c.

[0129] The first box body 43 and the second box body 44 enclose and form a first through hole 45 .

[0130] Alternatively, see Figure 10 As shown, the spray prevention liquid box 4 is provided with a second through hole 442, which is in communication with the accommodating chamber 4c. When the spray prevention liquid box 4 is in the second position, the branch connector 2 can extend from the main line pipe 1 through the first through hole 45, the accommodating chamber 4c, and the second through hole 442 to the outside of the spray prevention liquid box 4 on the side facing away from the main line pipe 1, thereby exposing the second interface 21 of the branch connector 2 to the outside of the spray prevention liquid box 4 on the side facing away from the main line pipe 1.

[0131] The second box body 44 encloses and forms a second through hole 442 .

[0132] Alternatively, see Figure 11As shown, the spray prevention box 4 also 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 and second boxes 43 and 44. When the spray prevention box 4 is in the first position and the second port 21 is not connected to the liquid cooler, the second port 21 is located within the spray prevention box 4. Accordingly, the first door 46 and the second door 47 can be used to cover the second through-hole 442. The first door 46 and the second door 47 can prevent coolant leaking from the second port 21 from being sprayed out of the spray prevention box 4 through the second through-hole 442. Before sliding the spray prevention 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 accommodating chamber 4c with the second through-hole 442. During the sliding process of the spray prevention box 4 from the first position to the second position, the second port 21 can be moved from the accommodating chamber 4c through the second through-hole 442 to the exterior of the spray prevention box 4 on the side facing away from the main pipe 1. After the second interface 21 is connected to the liquid cooling element, the first door body 46 and the second door body 47 are still located in the open position, so that the second interface 21 can be reset to the accommodating chamber 4c during the process of sliding the spray liquid prevention box 4 from the second position to the first position. At the same time, the liquid cooling element connected to the second interface 21 can also enter the accommodating chamber 4c through the second through hole 442, so that the connection structure between the second interface 21 and the liquid cooling element is located in the accommodating chamber 4c.

[0133] In other embodiments (not shown in the figures), the spray-proof liquid box may further include a soft plastic sheet (also known as a soft plastic film), and at least one of the first box body and the second box body is connected to the soft plastic sheet. In a natural state, the soft plastic sheet is used to cover the second through hole. Under the action of an external force, the soft plastic sheet can be elastically deformed, thereby allowing the accommodating cavity to communicate with the second through hole.

[0134] Alternatively, see Figure 11 As shown, the anti-spray liquid box 4 also includes a first toggle portion 48 and a second toggle portion 49. The first toggle portion 48 is connected to the first door body 46, and the second toggle portion 49 is connected to the second door body 47. At least part of the structure of the first toggle portion 48 and at least part of the structure of the second toggle portion 49 are located outside the first box body 43 and the second box body 44, so that the user's hand can reliably toggle the first toggle portion 48 and the second toggle portion 49, thereby reliably changing the positions of the first door body 46 and the second door body 47.

[0135] Optionally, the spray liquid prevention 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 body 43 and the second box body 44 via the first torsion spring, and the second door 47 is elastically connected to at least one of the first box body 43 and the second box body 44 via the second torsion spring. The first torsion spring and the second torsion spring are always in a state of accumulating elastic potential energy. That is, when 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 naturally cause the first door 46 to cover the second through hole 442, and the elastic force of the second torsion spring can naturally cause the second door 47 to cover the second through hole 442.

[0136] Based on the above, the installation process of the liquid cooling pipe structure 10 and the liquid cooling component in the embodiment of the present application is as follows:

[0137] When the second port 21 of the branch connector 2 is not connected to the liquid cooling element and the spray prevention box 4 is in the first position, the user can first manually move the first and second toggle portions 48 and 49 to move the first and second doors 46 and 47, thereby connecting the accommodating chamber 4c with the second through-hole 442. The user then manually pushes the first and second toggle portions 48 and 49 in a direction opposite to the X direction, sliding the spray prevention box 4 from the first position to the second position. During this sliding process, the accommodating chamber 4c remains connected to the second through-hole 442, and the first and second doors 46 and 47 are positioned so as not to interfere with the second port 21. This allows the second port 21 to move from the accommodating chamber 4c through the second through-hole 442 to the exterior of the spray prevention box 4, facing away from the main pipe 1. The user can then connect the liquid cooling element to the second port 21. Finally, the user returns the spray prevention box 4 to the first position.

[0138] Based on the above content, the disassembly process of the liquid cooling pipe structure 10 and the liquid cooling component in the embodiment of the present application is as follows:

[0139] When the second port 21 of the branch connector 2 is connected to the liquid cooling element and the spray prevention box 4 is in the first position, the user firstly moves the first and second toggle members 48 and 49 to move the first and second doors 46 and 47 so that they do not interfere with the liquid cooling element and the second port 21 during subsequent sliding. The user then pushes the first and second toggle members 48 and 49 in a direction opposite to the X direction to slide the spray prevention box 4 from the first position to the second position. This allows the liquid cooling element and the second port 21 to move from the accommodating chamber 4c through the second through-hole 442 to the exterior of the spray prevention box 4, facing away from the main pipe 1. The user can then remove the liquid cooling element and the second port 21. Finally, the user returns the spray prevention box 4 to the first position and, by moving the first and second toggle members 48 and 49, moves the first and second doors 46 and 47 to a position where they cover the second through-hole 442.

[0140] Alternatively, see Figure 12 As shown, the liquid cooling pipe structure 10 also includes a quick-connect pipe 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 pipe 6. Before the liquid cooling pipe structure 10 is installed in the cabinet body of the liquid cooling cabinet, the main pipe 1 needs to be filled with coolant and the gas needs to be exhausted. The gas in the main pipe 1 can be discharged to the outside of the liquid cooling pipe structure 10 through the quick-connect pipe 6 and the exhaust valve 7. After the gas is exhausted, the exhaust valve 7 can be removed to reduce the volume of the liquid cooling pipe structure 10. Accordingly, the space occupied by the liquid cooling pipe structure 10 in the liquid cooling cabinet is reduced, which can save the internal space of the liquid cooling cabinet.

[0141] The quick-connect pipe 6 can be adapted to exhaust valves of different structural types.

[0142] Optionally, in Figure 13 Please refer to the perspective shown. Figure 14 As shown, the liquid cooling pipeline structure 10 further includes a liquid drain pipe 8 , which includes a main drain pipe 81 and at least two liquid receiving funnels 82 , each of which corresponds to each spray prevention box 4 .

[0143] Please refer to Figure 9 As shown, the spray prevention box 4 is provided with a drainage channel 441, which is connected to the accommodating chamber 4c. When the second interface 21 leaks coolant, the leaked coolant can flow out of the accommodating chamber 4c through the drainage channel 441. Figure 14 As shown, the coolant flowing out of the drainage channel 441 will fall into the corresponding liquid receiving funnel 82 located below, and the leaked coolant will eventually enter the main drainage pipe 81.

[0144] The exhaust pipe of the exhaust valve 7 can be connected to the top end of the main exhaust pipe 81 so that the trace liquid carried in the gas exhausted by the exhaust valve 7 can be discharged into the main exhaust pipe 81.

[0145] In addition, the main drain pipe 81 can be connected to the side wall of the main pipe 1 by means of snap connection, bonding, hanging, magnetic attraction or fastening connection.

[0146] Alternatively, see Figure 15 As shown, the liquid cooling pipeline structure 10 also includes a liquid receiving pan 9, which is used to receive the liquid discharged from the bottom of the main drain pipe 81. The liquid receiving pan 9 is also used to guide the liquid to flow into the liquid accumulation pan at the bottom of the liquid cooling cabinet (not shown in the figure).

[0147] Alternatively, see Figure 15 As shown, the bottom of the main pipe 1 includes a liquid inlet 11, and external coolant can flow into the main pipe 1 through the liquid inlet 11.

[0148] It should be noted that the liquid cooling piping structure described above can function as a liquid distributor. The second interface of the branch connector of the liquid cooling piping structure can be connected to the liquid inlet of a liquid cooling component, thereby dividing the coolant into at least two branches, each of which can flow to a corresponding liquid cooling component. Of course, the liquid cooling piping structure described above can also function as a liquid collector. The second interface of the branch connector of the liquid cooling piping structure can be connected to the liquid outlet of a liquid cooling component, so that the branches within each liquid cooling component are combined within the liquid cooling piping structure.

[0149] In a second aspect, the present application provides a liquid-cooled cabinet comprising a cabinet body, a liquid distributor, a liquid collector, and at least two liquid-cooled components. The liquid distributor, the liquid collector, and the at least two liquid-cooled components are all removably mounted within the cabinet body. The liquid distributor is used to distribute coolant to each liquid-cooled component, and the liquid collector is used to collect coolant from each liquid-cooled component. Both the liquid distributor and the liquid collector utilize the liquid-cooled piping structure 10 described above. Each liquid-cooled component has a liquid inlet and a liquid outlet. The liquid inlet is connected to the second interface of the branch connector of the liquid distributor, and the liquid outlet is connected to the second interface of the branch connector of the liquid collector. When the coolant outside the cabinet body enters the liquid separator, the liquid separator divides the coolant into multiple branches. Each branch flows to the corresponding liquid cooling component. The branches in the liquid cooling component absorb the heat of the corresponding heating device. The branches in each liquid cooling component are then collected through the liquid collector. The liquid collector drains the coolant to the outside of the cabinet body. The coolant dissipates heat outside the cabinet body and then flows back to the liquid separator after dissipation, thus realizing the heat dissipation cycle described above.

[0150] The liquid separator and the liquid collector can be arranged at intervals, which is convenient for users to separately check and maintain the connection structure between the liquid separator and the liquid cooling component, and also convenient for users to separately check and maintain the connection structure between the liquid collector and the liquid cooling component.

[0151] In addition, the structure of the liquid distributor and the structure of the liquid collector can be arranged symmetrically.

[0152] In other embodiments, the liquid separator and the liquid collector may be detachably connected.

[0153] In other embodiments, the liquid distributor and the liquid collector may belong to different modules in the same device.

[0154] It should be noted that both the liquid inlet and outlet can be male connectors of quick-disconnect connectors, meaning they are designed to plug into the second interface of the branch connector. Specifically, both the liquid inlet and outlet can be male connectors of blind-mate fluid connectors. This arrangement facilitates quick assembly and disassembly of the branch connector and the liquid cooling unit.

[0155] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
