Description

Technical Field

[0001] The present application relates to the field of liquid cooling and heat dissipation technology, and in particular to a liquid spray prevention box, 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 electronic devices such as large computers and servers is increasing. High-computing electronic devices will generate a lot of heat during operation, so liquid cooling cabinets are needed to dissipate the heat of high-computing electronic devices.

[0003] In the related art, a liquid-cooling cabinet includes two liquid-cooling pipeline structures and at least two liquid-cooling components, wherein one of the liquid-cooling pipeline structures is connected to at least two liquid-cooling components, and at least two liquid-cooling components are connected to another liquid-cooling pipeline structure. One of the liquid-cooling pipeline structures can play a role in liquid separation, that is, one of the liquid-cooling pipeline structures can divert the coolant to each liquid-cooling component, each liquid-cooling component is used to cool different electronic equipment, and the other liquid-cooling pipeline structure can play a role in liquid collection, so that the coolant in each liquid-cooling component is collected to another liquid-cooling pipeline structure. In addition, in some solutions, the liquid-cooling pipeline structure is equipped with a liquid spray prevention box, which is used to cover the connection structure between the liquid-cooling pipeline structure and the liquid-cooling component to reduce the possibility of liquid leaking from the connection structure being directly sprayed onto the electronic equipment.

[0004] In the process of implementing the invention, the inventors found that there are at least the following problems in the related art: The volume of the liquid cooling pipeline structure is relatively large, and the liquid cooling pipeline structure occupies more internal space of the liquid cooling cabinet. Summary of the invention

[0005] The present application provides a liquid spray prevention box, a liquid cooling pipeline structure and a liquid cooling cabinet, which can improve the problem in the prior art that the liquid cooling pipeline structure occupies a large amount of internal space of the liquid cooling cabinet.

[0006] In a first aspect, the present application provides a liquid spray prevention box, which is provided with a connected accommodating chamber, a first through hole and a second through hole, the first through hole being used to be penetrated by a branch connector of a liquid cooling pipeline structure, the second through hole being used to be penetrated by a liquid cooling joint of a liquid cooling part, the accommodating chamber being used to accommodate a connecting structure between the branch connector and the liquid cooling joint; the liquid spray prevention box also includes a liquid inlet structure and a liquid discharge structure, the liquid inlet structure being used for liquid located outside the liquid spray prevention box to enter the accommodating chamber, and the liquid discharge structure being used to discharge liquid located in the accommodating chamber.

[0007] Among them, the connection structure between the branch connector and the liquid cooling joint of the liquid cooling pipeline structure is used to circulate the cooling liquid. When the liquid cooling pipeline structure acts as a liquid distributor, the cooling liquid can flow from the liquid cooling pipeline structure to the liquid cooling part via the branch connector and the liquid cooling joint in sequence. When the liquid cooling pipeline structure acts as a liquid collector, the cooling liquid can flow from the liquid cooling part to the liquid cooling pipeline structure via the liquid cooling joint and the branch connector in sequence. Since the detachable connection structure between the branch connector and the liquid cooling joint is in the accommodating chamber, when the detachable connection structure between the branch connector and the liquid cooling joint leaks, the liquid leaked from the detachable connection structure between the branch connector and the liquid cooling joint can be better blocked by the spray prevention box in the spray prevention box accommodating chamber, reducing the leaked liquid from being directly sprayed onto the electronic equipment, thereby reducing the risk of failure of the electronic equipment.

[0008] In the liquid cooling pipeline structure, if at least two spray liquid prevention boxes are distributed in the height direction of the liquid cooling pipeline structure, the liquid in the accommodating chamber of the spray liquid prevention box located above can drop to the liquid inlet structure of the spray liquid prevention box located below via the liquid discharge structure of the spray liquid prevention box located above, and the falling liquid then enters the accommodating chamber of the spray liquid prevention box located below, and the liquid in the accommodating chamber of the spray liquid prevention box located below can drop to the spray liquid prevention box further below via the liquid discharge structure of the spray liquid prevention box located below or fall into the structural member for recovering liquid at the bottom of the liquid cooling pipeline structure.

[0009] Optionally, the liquid inlet structure is provided with a liquid inlet, and the liquid discharge structure is provided with a liquid discharge port, the height of the liquid inlet is higher than the height of the liquid discharge port; the range of the projection of the liquid discharge port in the height direction of the spray liquid prevention box is within the range of the projection of the liquid inlet in the height direction.

[0010] Optionally, any cross section of the liquid inlet perpendicular to the height direction is extended along a direction from the first through hole to the second through hole.

[0011] Optionally, any cross-section of the liquid inlet perpendicular to the height direction has a shape of a rectangle, an ellipse or a trapezoid.

[0012] Optionally, the liquid discharge port is arranged on the bottom wall of the spray-proof liquid box; the area of ​​any cross section of the liquid discharge port perpendicular to the height direction decreases along the direction from the top wall of the spray-proof liquid box to the bottom wall of the spray-proof liquid box.

[0013] Optionally, the shape of the drain port includes a truncated cone and / or a truncated pyramid.

[0014] Optionally, the spray-proof box comprises a first side wall and a second side wall which are spaced apart, the first side wall is provided with the first through hole, and the second side wall is provided with the second through hole; and a ratio of a distance between the liquid discharge port and the first side wall to a distance between the liquid discharge port and the second side wall is in a range of 0.8 to 1.2.

[0015] Optionally, the spray-proof liquid box comprises a first box body and a second box body, and the first box body is detachably connected to the second box body; the liquid inlet structure is arranged on the first box body, and the liquid discharge structure is arranged on the second box body.

[0016] In a second aspect, the present application provides a liquid cooling pipeline structure, which includes at least two spray liquid prevention boxes as described above; the at least two spray liquid prevention boxes are distributed along the height direction of the liquid cooling pipeline structure; the liquid discharge structure of the spray liquid prevention box located at a higher position is used to discharge liquid into the liquid inlet structure of the spray liquid prevention box located at a lower position.

[0017] In a third aspect, the present application provides a liquid-cooling cabinet, which includes a cabinet body, a liquid distributor, a liquid collector and at least two liquid-cooling components, wherein the liquid distributor, the liquid collector and the at least two liquid-cooling components can be removably installed in the cabinet body; the liquid distributor is removably connected to the at least two liquid-cooling components, and the liquid collector is removably connected to the at least two liquid-cooling components, and the liquid distributor and the liquid collector both adopt the liquid cooling pipeline structure described above.

[0018] It can be seen that compared with the prior art, the technical solution provided by this application has at least the following beneficial effects: The structure of the anti-spray box provided in the present application has the function of blocking leaked liquid from being directly sprayed onto the electronic equipment, and also integrates a drainage function. Therefore, the liquid cooling pipeline structure equipped with the anti-spray box of the present application may not be provided with a drainage pipe, so that the volume of the liquid cooling pipeline structure is relatively small, thereby making the internal space of the liquid cooling cabinet occupied by the liquid cooling pipeline structure relatively small. In summary, the liquid cooling pipeline structure using the anti-spray box provided in the present application can improve the problem of the liquid cooling pipeline structure occupying a large amount of internal space of the liquid cooling cabinet existing in the prior art.

DETAILED DESCRIPTION

[0022] 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.

[0023] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the protection scope of the present application.

[0024] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" 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 other meanings. It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] In a first aspect, an embodiment of the present application provides a spray liquid prevention box, which is a structural component of a liquid cooling pipeline structure.

[0026] Please refer to Figure 1 As shown, the spray-proof liquid box 10 is provided with a first through hole 10a, please refer to Figure 2 As shown, the spray-proof liquid box 10 is provided with a second through hole 10b. Figure 1-Figure 2 As shown, the spray-proof liquid box 10 is further provided with a receiving chamber 10c, and the first through hole 10a, the receiving chamber 10c and the second through hole 10b are communicated.

[0027] The first through hole 10a is used for a branch connector (e.g., a male connector) of a liquid cooling pipe structure (not shown in the figure) to pass through, the second through hole 10b is used for a liquid cooling connector (e.g., a female connector) of a liquid cooling component (not shown in the figure) to pass through, and the accommodating cavity 10c is used to accommodate a detachable connection structure between the branch connector and the liquid cooling connector. It can be understood that the branch connector and the liquid cooling connector are paired structural parts, and generally use quick connectors, especially blind plug quick connectors.

[0028] It should be noted that in the drawings herein, directions X, Y and Z are perpendicular to each other, wherein direction Z represents a direction from the top of the spray-proof liquid box 10 to the bottom of the spray-proof liquid box 10 , and direction Z can also be understood as the height direction of the spray-proof liquid box 10 .

[0029] The connection structure between the branch connector and the liquid cooling joint is used to circulate the coolant. When the liquid cooling pipeline structure is used as a liquid distributor, the coolant can flow from the liquid cooling pipeline structure to the liquid cooling component via the branch connector and the liquid cooling joint in sequence. When the liquid cooling pipeline structure is used as a liquid collector, the coolant can flow from the liquid cooling component to the liquid cooling pipeline structure via the liquid cooling joint and the branch connector in sequence. The liquid cooling component is used to cool electronic equipment (such as large computers, servers, graphics processing units GPU or central processing units CPU).

[0030] Since the detachable connecting structure between the branch connector and the liquid cooling joint is in the accommodating chamber 10c, when leakage occurs in the detachable connecting structure between the branch connector and the liquid cooling joint, the liquid leaked from the detachable connecting structure between the branch connector and the liquid cooling joint can be better blocked by the anti-spray box in the accommodating chamber 10c, thereby reducing the leaked liquid from being directly sprayed onto the electronic equipment, thereby reducing the risk of malfunction of the electronic equipment.

[0031] Please refer to Figure 1-Figure 2 As shown, the spray-proof liquid box 10 also includes a liquid inlet structure 11, please refer to Figure 3 As shown, the spray-proof liquid box 10 further includes a liquid discharge structure 21. The liquid inlet structure 11 is used for the liquid outside the spray-proof liquid box 10 to enter the accommodating chamber 10c, and the liquid discharge structure 21 is used for discharging the liquid in the accommodating chamber 10c.

[0032] It should be noted that the "liquid outside the spray prevention box 10" is the liquid discharged by the structural member with liquid discharge function in the liquid cooling pipeline structure. The structural member with liquid discharge function in the liquid cooling pipeline structure may include at least one of the spray prevention box, the pressure relief pipe and the exhaust pipe.

[0033] Taking the liquid cooling pipeline structure as an example, the structure with the function of draining liquid includes a liquid spray prevention box, when the liquid cooling pipeline structure includes at least two Figure 4 The spray-proof liquid boxes 10 are distributed in the height direction as shown. Figure 5 As shown, the liquid in the accommodating chamber 10c of the spray liquid prevention box 10 located at the top can drop to the liquid inlet structure 11 of the spray liquid prevention box 10 located at the bottom through the liquid discharge structure 21 of the spray liquid prevention box 10 located at the top, and the falling liquid then enters the accommodating chamber 10c of the spray liquid prevention box 10 located at the bottom, and the liquid in the accommodating chamber 10c of the spray liquid prevention box 10 located at the bottom can drop to the spray liquid prevention box (not shown in the figure) further below through the liquid discharge structure 21 of the spray liquid prevention box 10 located at the bottom, or fall into the liquid collecting tray (not shown in the figure) at the bottom of the liquid cooling pipeline structure.

[0034] In the related art, the liquid cooling pipeline structure needs to be provided with a drain pipe to receive the liquid discharged from each spray prevention box respectively, so that the drain pipe needs to be extended along the height direction of the liquid cooling pipeline structure, which makes the volume of the drain pipe relatively large. On the one hand, the volume of the liquid cooling pipeline structure in the related art is relatively large, so that the internal space of the liquid cooling cabinet occupied by the liquid cooling pipeline structure in the related art is relatively large, and the volume of the electronic equipment that can be stored in the liquid cooling cabinet is relatively small, or the volume of the liquid cooling cabinet needs to be designed to be relatively large; on the other hand, the structural complexity of the liquid cooling pipeline structure in the related art is relatively high, so that the manufacturing difficulty, assembly difficulty and maintenance difficulty of the liquid cooling pipeline structure in the related art are relatively large.

[0035] Compared with the above-mentioned related technologies, the structure of the anti-spray box provided in the embodiment of the present application has the function of blocking the leaked liquid from being directly sprayed onto the electronic equipment, and also integrates the drainage function of the above-mentioned drain pipe. Therefore, the liquid cooling pipeline structure with the anti-spray box of the embodiment of the present application can be provided with no drain pipe, which, on the one hand, makes the volume of the liquid cooling pipeline structure relatively small, so that the internal space of the liquid cooling cabinet occupied by the liquid cooling pipeline structure is relatively small, and the volume of the electronic equipment that can be stored in the liquid cooling cabinet is relatively large, or the volume of the liquid cooling cabinet can be relatively small; on the other hand, the structural complexity of the liquid cooling pipeline structure is relatively low, so that the difficulty of manufacturing, assembling and maintaining the liquid cooling pipeline structure are relatively small.

[0036] Taking the structure with drainage function in the liquid cooling pipeline structure including the pressure relief pipe (not shown in the figure) as an example, when the liquid pressure inside the liquid cooling pipeline structure is too high, the pressure relief pipe can discharge a part of the liquid to reduce the liquid pressure inside the liquid cooling pipeline structure, thereby reducing the possibility of liquid leakage in the liquid cooling pipeline structure. The liquid discharged by the pressure relief pipe can be discharged through Figure 5 The liquid inlet structure 11 of the upper spray-proof liquid box 10 shown enters the accommodating chamber 10c of the spray-proof liquid box 10, and the liquid in the accommodating chamber 10c of the upper spray-proof liquid box 10 is then discharged into the lower spray-proof liquid box 10 through the liquid discharge structure 21 of the upper spray-proof liquid box 10.

[0037] Compared with the related art in which the liquid cooling pipeline structure needs to use a drain pipe to discharge the liquid discharged by the pressure relief pipe, the structural setting of the anti-spray box in the embodiment of the present application can reduce the volume of the liquid cooling pipeline structure and the structural complexity of the liquid cooling pipeline structure. The relevant specific effects have been described above and will not be repeated here.

[0038] Generally, there is no spray preventer box 10 disposed above the spray preventer box 10 located at the top, so the liquid discharged from the pressure relief pipe can enter the accommodating cavity 10c of the spray preventer box 10 located at the top through the liquid inlet structure 11 of the spray preventer box 10 located at the top.

[0039] Of course, in other embodiments, the liquid discharged from the pressure relief pipe may also enter the accommodating cavity 10c of the non-uppermost spray preventer box 10 through the liquid inlet structure 11 of the non-uppermost spray preventer box 10 .

[0040] For example, the exhaust pipe is a structural part with a discharge function in the liquid cooling pipeline structure. When there is gas inside the liquid cooling pipeline structure, the exhaust pipe can discharge the gas to improve the liquid cooling efficiency. The gas discharged by the exhaust pipe may carry a small amount of liquid, and if the temperature of the ejected gas is lower than the temperature of the surrounding air, the ejected gas will also cause the water vapor around the outlet of the exhaust pipe to condense into liquid. Therefore, the exhaust pipe will also discharge liquid when exhausting. The liquid discharged by the exhaust pipe can be discharged through the following channels: Figure 5 The liquid inlet structure 11 of the upper spray-proof liquid box 10 shown enters the accommodating chamber 10c of the spray-proof liquid box 10, and the liquid in the accommodating chamber 10c of the upper spray-proof liquid box 10 is then discharged into the lower spray-proof liquid box 10 through the liquid discharge structure 21 of the upper spray-proof liquid box 10.

[0041] Compared with the related art in which the liquid cooling pipeline structure needs to use a drain pipe to discharge the liquid discharged from the exhaust pipe, the structural setting of the anti-spray box in the embodiment of the present application can reduce the volume of the liquid cooling pipeline structure and the structural complexity of the liquid cooling pipeline structure. The relevant specific effects have been described above and will not be repeated here.

[0042] The following content of this article mainly describes the example of the liquid inlet structure of the spray prevention liquid box being used to receive the liquid discharged by the spray prevention liquid box located above.

[0043] Generally, there is no spray liquid box 10 disposed above the spray liquid box 10 located at the top. Therefore, the liquid discharged from the exhaust pipe can enter the accommodating cavity 10c of the spray liquid box 10 located at the top through the liquid inlet structure 11 of the spray liquid box 10 located at the top.

[0044] Of course, in other embodiments, the liquid discharged from the exhaust pipe may also enter the accommodating cavity 10 c of the non-uppermost spray liquid prevention box 10 through the liquid inlet structure 11 of the non-uppermost spray liquid prevention box 10 .

[0045] It should be noted that the liquid discharge structure 21 of the spray prevention box 10 at the bottom is used to discharge the liquid to a liquid collection tray (not shown) at the bottom of the liquid cooling pipeline structure or other pipelines or containers for recovering liquid.

[0046] Optionally, see Figure 5 As shown, in the same spray liquid prevention box 10, the liquid inlet structure 11 is provided with a liquid inlet 11a, and the liquid discharge structure 21 is provided with a liquid discharge port 21a. The height of the position of the liquid inlet 11a is higher than the height of the position of the liquid discharge port 21a. The projection range of the liquid discharge port 21a in the height direction of the spray liquid prevention box 10 is within the projection range of the liquid inlet 11a in the height direction. Under this setting, if the liquid cooling pipeline structure includes at least two as Figure 5 When the spray-proof liquid boxes 10 are distributed in the height direction as shown, on the one hand, the liquid discharged from the liquid discharge port 21a of the spray-proof liquid box 10 located at the upper side can accurately fall into the liquid inlet 11a of the spray-proof liquid box 10 located at the lower side, reducing the possibility of the problem that the liquid discharged from the spray-proof liquid box 10 located at the upper side does not fall into the spray-proof liquid box 10 located at the lower side, thereby making it possible to have at least two Figure 5The liquid cooling pipeline structure of the spray liquid prevention box 10 distributed in the height direction as shown can discharge the liquid reliably and effectively. On the other hand, in the same spray liquid prevention box 10, the path between the liquid inlet 11a and the liquid discharge port 21a in the height direction is relatively short, and the falling liquid stays in the same spray liquid prevention box 10 for a relatively short time, so that at least two Figure 5 The liquid cooling pipeline structure of the spray-proof liquid box 10 distributed in the height direction as shown can quickly discharge liquid, reduce the risk of excessive liquid accumulation in the accommodating cavity 10c of any spray-proof liquid box 10, and thus reduce the risk of liquid leakage from other hole structures of the spray-proof liquid box 10 that are not used for liquid discharge.

[0047] In other embodiments (not shown in the figure), on the basis of "the range of the projection of the discharge port in the height direction is within the range of the projection of the liquid inlet in the height direction", at least one of the liquid inlet structure and the liquid discharge structure may have a retractable structure. If the liquid inlet structure has a retractable structure, the liquid inlet structure of the spray liquid prevention box located below can be extended toward the liquid discharge structure of the spray liquid prevention box located above, so that the liquid inlet of the spray liquid prevention box located below is closer to the liquid discharge port of the spray liquid prevention box located above, thereby improving the accuracy of the liquid discharged by the spray liquid prevention box located above falling into the spray liquid prevention box located below. If the liquid discharge structure has a retractable structure, the liquid discharge structure of the spray liquid prevention box located above can be extended toward the liquid inlet structure of the spray liquid prevention box located below, so that the liquid discharge port of the spray liquid prevention box located above is closer to the liquid inlet of the spray liquid prevention box located below, thereby improving the accuracy of the liquid discharged by the spray liquid prevention box located above falling into the spray liquid prevention box located below.

[0048] In other embodiments, please refer to Figure 6 As shown, in the same spray liquid prevention box 10, the projection range of the discharge port 21a in the height direction may not be within the projection range of the inlet port 11a in the height direction. Figure 6 The spray-proof liquid boxes 10 with different structures distributed in the height direction shown in the figure, but the projection range of the discharge port 21a of the spray-proof liquid box 10 located at the top in the height direction needs to be within the projection range of the liquid inlet 11a of the spray-proof liquid box 10 located at the bottom in the height direction. Under this arrangement, on the one hand, the liquid discharged from the discharge port 21a of the spray-proof liquid box 10 located at the top can accurately fall into the liquid inlet 11a of the spray-proof liquid box 10 located at the bottom, reducing the possibility of the problem that the liquid discharged from the spray-proof liquid box 10 located at the top does not fall into the spray-proof liquid box 10 located at the bottom, so that the spray-proof liquid box 10 with at least two structures as shown in the figure can be arranged in the height direction. Figure 6The liquid cooling pipeline structure of the spray liquid prevention box 10 distributed in the height direction with different structures shown can discharge liquid reliably and effectively. On the other hand, when the liquid discharged from the spray liquid prevention box 10 located above falls into the spray liquid prevention box 10 located below, the falling liquid will be buffered by the structural wall of the spray liquid prevention box 10 located below, so as to reduce the falling speed of the liquid, so as to reduce the speed of the liquid when it falls into the liquid collection tray at the bottom of the liquid cooling pipeline structure, so as to reduce the risk of liquid with excessive kinetic energy splashing from the liquid collection tray to other positions not used for collecting liquid, so that the liquid collection tray can reliably collect the liquid.

[0049] In other embodiments (not shown in the figure), at least one of the liquid inlet structure and the liquid discharge structure may have a flexible structure, and the flexible structure may include a hose. If the liquid inlet structure includes a hose, the hose of the liquid inlet structure of the spray liquid prevention box located below can be connected to the liquid discharge structure of the spray liquid prevention box located above, for example, the hose is sleeved in the liquid discharge structure. If the liquid discharge structure includes a hose, the hose of the liquid discharge structure of the spray liquid prevention box located above can be connected to the liquid inlet structure of the spray liquid prevention box located below, for example, the hose is sleeved in the liquid inlet structure. On the one hand, the reliability of the liquid discharged by the spray liquid prevention box located above falling into the spray liquid prevention box located below is improved, and on the other hand, even if the spray liquid prevention box moves relative to the branch connection piece, the hose itself can be flexibly deformed, so that the liquid inlet structure and the liquid discharge structure are still reliably connected, and the liquid discharged by the spray liquid prevention box located above can still reliably fall into the spray liquid prevention box located below.

[0050] The following content of this article mainly focuses on Figure 5 The spray-preventing box 10 is introduced by taking the example that “in the same spray-preventing box 10, the projection range of the liquid discharge port 21a in the height direction is within the projection range of the liquid inlet port 11a in the height direction”.

[0051] In some application scenarios, the spray-proof liquid box needs to be moved relative to the branch connection, such as Figure 4 Any spray liquid prevention box 10 shown is moved along the direction X so that the joint in the branch connection piece for connecting with the liquid cooling piece is moved from the accommodating cavity of the spray liquid prevention box 10 to the outside of the spray liquid prevention box 10, so that the operator can observe the joint in the branch connection piece for connecting with the liquid cooling piece. In this application scenario, please refer to Figure 1 As shown, any cross section of the liquid inlet 11a perpendicular to the height direction can be extended along the direction from the first through hole 10a to the second through hole 10b (the opposite direction of the direction X). Figure 4As shown, even if the spray-proof liquid box 10 located at the bottom moves, the projection range of the discharge port 21a of the spray-proof liquid box 10 located at the top and not moved in the height direction is still within the projection range of the liquid inlet 11a of the spray-proof liquid box 10 located at the bottom and moved in the height direction, so that the spray-proof liquid box 10 located at the top and not moved can also discharge liquid into the discharge liquid box 10 located at the bottom and moved, reducing the possibility of the problem that the liquid discharged by the spray-proof liquid box 10 located at the top and not moved does not fall into the spray-proof liquid box 10 located at the bottom and moved. Similarly, even if the spray-proof liquid box 10 located at the top and not moved moves, the discharge port 21a of the spray-proof liquid box 10 located at the top and not moved moves. When the spray liquid box 10 moves, the projection range of the discharge port 21a of the upper moved spray liquid prevention box 10 in the height direction is still within the projection range of the liquid inlet 11a of the lower non-moved spray liquid prevention box 10 in the height direction, so that the upper moved spray liquid prevention box 10 can also discharge liquid into the lower non-moved discharge liquid box 10, reducing the possibility of the problem that the liquid discharged by the upper moved spray liquid prevention box 10 does not fall into the lower non-moved spray liquid prevention box 10, so that the liquid cooling pipeline structure can reliably and effectively discharge liquid.

[0052] Please refer to Figure 7 As shown, the liquid inlet 11a may be located on the top wall 10d of the spray-proof liquid box 10, and the top wall 10d may be perpendicular to the height direction.

[0053] In other embodiments, please refer to Figure 8-Figure 9 As shown, the top wall 10d may have an acute angle or an obtuse angle with the height direction. In other words, the top wall 10d is inclined relative to the height direction.

[0054] In other embodiments, please refer to Fig.10 As shown, the liquid inlet 11a may be located on a structural wall of the spray-proof liquid box 10 that is lower than the top wall 10d.

[0055] Optionally, see Figure 1 and Figure 5 As shown, the shape of any cross section of the liquid inlet 11a perpendicular to the height direction includes a rectangle.

[0056] The rectangle may be a rectangle with right angles, a rectangle with chamfered right angles, or a rectangle with chamfered corners.

[0057] In addition, the dimension of the rectangular liquid inlet 11 a in the X direction is greater than the dimension in the Y direction.

[0058] In other embodiments, the shape of any cross section of the liquid inlet 11a perpendicular to the height direction may also include: Fig.11 The trapezoid shown or Fig.12 The oval shown.

[0059] About Figure 7 The liquid inlet 11a shown, the liquid inlet structure 11 provided with the liquid inlet 11a can also be at least a partial structure of the top wall 10d, and the size of the liquid inlet 11a in the height direction can be equal to the size of the top wall 10d in the height direction.

[0060] In other embodiments, please refer to Fig.13 As shown, the liquid inlet structure 11 may also be a structure that is raised relative to the top wall 10d, and the size of the liquid inlet 11a in the height direction may be greater than the size of the top wall 10d in the height direction.

[0061] In other embodiments, please refer to Fig.14 As shown, the liquid inlet structure 11 can be a structure protruding relative to the side wall of the spray-proof liquid box.

[0062] regardless Figure 7 to Figure 14 Any structural setting of the liquid inlet structure 11 must satisfy the requirement that the liquid inlet structure 11 can receive liquid moving from top to bottom.

[0063] The following content of this article mainly focuses on Figure 1 The liquid inlet structure 11 and the liquid inlet 11a shown are described as examples.

[0064] Optionally, see Fig.15 As shown, the liquid discharge port 21a is arranged on the bottom wall 10e of the spray liquid prevention box 10, and the area of ​​any cross section of the liquid discharge port 21a perpendicular to the height direction decreases along the direction (direction Z) from the top wall 10d of the spray liquid prevention box to the bottom wall 10e of the spray liquid prevention box. Under this arrangement, when the liquid discharge port 21a discharges liquid downward, it has the effect of converging the liquid, so as to reduce the possibility of dispersion of the discharged liquid, thereby improving the accuracy of the liquid falling into the liquid inlet 11a of the spray liquid prevention box located below.

[0065] Optionally, see Fig.15 As shown, the shape of the discharge port 21a includes a truncated cone shape.

[0066] In other embodiments (not shown in the figures), the shape of the liquid discharge port 21 a may also include a truncated pyramid.

[0067] In other embodiments (not shown in the figures), the liquid discharge port 21a may also include two sections distributed vertically, wherein the shape of one section may include a truncated cone, and the shape of the other section may include a truncated pyramid.

[0068] The following content of this article mainly describes the shape of the discharge port 21a as a truncated cone.

[0069] The outer curved surface wall of the drainage structure 21 is the same as or similar to the outer curved surface wall of the truncated cone.

[0070] In other embodiments, the drainage structure 21 and the drainage port 21a provided on the bottom wall 10e may be as follows: Fig.16 As shown or Fig.17 shown.

[0071] In other embodiments, please refer to Fig.18 As shown, the liquid discharge structure 21 and the liquid discharge port 21a may also be disposed at the junction of the bottom wall 10e of the spray-proof liquid box and the side wall of the spray-proof liquid box.

[0072] The following content of this article mainly focuses on Fig.15 The drainage structure 21 and the drainage port 21a shown are introduced as examples.

[0073] Optionally, see Fig.19 As shown, the spray-proof liquid box 10 includes a first side wall 10f and a second side wall 10g which are spaced apart. The first side wall 10f is provided with a first through hole 10a, and the second side wall 10g is provided with a second through hole 10b. The distance d between the discharge port 21a and the first side wall 10f is 1 The distance d between the discharge port 21a and the second side wall 10g is 2 The ratio is in the range of 0.8~1.2, where the distance d 1 With distance d 2 The ratio can be specifically 0.8, 0.9, 1, 1.1 or 1.2. When the ratio is less than 0.8, the discharge port 21a is too close to the first side wall 10f, and when the spray liquid prevention box 10 moves relative to the branch connection piece along the direction X, at least part of the projection range of the discharge port 21a of the moved spray liquid prevention box 10 in the height direction is likely to be outside the projection range of the liquid inlet 11a of the spray liquid prevention box 10 that has not been moved below in the height direction, so that the liquid discharged from the discharge port 21a of the moved spray liquid prevention box 10 is not likely to fall into the spray liquid prevention box 10 that has not been moved below. When the ratio is greater than 1.2, the discharge port 21a is too close to the second side wall 10g. When the spray liquid box 10 moves relative to the branch connection piece along the direction X, at least part of the projection range of the discharge port 21a of the spray liquid box 10 located above and not moved in the height direction is likely to be outside the projection range of the liquid inlet 11a of the spray liquid box 10 located below and moved in the height direction, so that the liquid discharged from the discharge port 21a of the spray liquid box 10 located above and not moved is not easy to fall into the spray liquid box 10 located below and moved. Therefore, the distance d 1 With distance d 2 The ratio is preferably within the range of 0.8 to 1.2, so that the liquid discharged from the discharge port 21a of the spray-proof liquid box 10 located above can easily fall into the spray-proof liquid box 10 located below.

[0074] It should be noted that if the shape of the discharge port 21a includes a truncated cone or a cylindrical shape, the axis of the discharge port 21a can be used as the distance reference, that is, the distance d 1 is the distance between the axis of the discharge port 21a and the first side wall 10f, and the distance d 2 The distance d is the distance between the axis of the discharge port 21a and the second side wall 10g. Of course, the inner wall surface of the discharge structure 21 used to enclose the discharge port 21a can also be used as the distance reference, that is, the distance d 1 is the shortest distance between the inner wall surface of the drainage structure 21 and the first side wall 10f, and the distance d 2 It is the shortest distance between the inner wall surface of the drainage structure 21 and the second side wall 10g.

[0075] Optionally, a first path is set between the liquid inlet structure 11 and the liquid discharge structure 21, and a second path is set between the first through hole 10a and the second through hole 10b. The first path and the second path each have a certain size in the direction X, the direction Y and the direction Z, and the first path and the second path do not intersect. Under this setting, in the same spray-proof liquid box 10, when the liquid falls from the liquid inlet structure 11 to the liquid discharge structure 21, the movement of the liquid is not easily interfered by the branch connection member (not shown in the figure) penetrating the first through hole 10a, so as to reduce the possibility that the liquid is rebounded by the branch connection member during the falling process and then splashed out of the spray-proof liquid box 10 through the liquid inlet structure 11.

[0076] Optionally, the number of the liquid inlet structures 11 of the spray-proof liquid box 10 can be one, two, or three or more. The number of the liquid discharge structures 21 of the spray-proof liquid box 10 can be one, two, or three or more.

[0077] Optionally, see Fig. 20 As shown, the spray-proof liquid box 10 includes a first box body 1 and a second box body 2, and the first box body 1 and the second box body 2 are detachably connected. Fig.21 As shown, the liquid inlet structure 11 is arranged on the first box body 1, please refer to Fig. 22 As shown, the liquid discharge structure 21 is arranged on the second box body 2. Under this arrangement, on the one hand, the first box body 1 with liquid inlet structures 11 of different structural types (sizes, shapes) and the second box body 2 with liquid discharge structures 21 of different structural types (sizes, shapes) can be assembled into anti-spray boxes 10 of different structural types (sizes, shapes) to meet different liquid discharge performances, such as a higher liquid discharge rate, better liquid discharge reliability, and other liquid discharge performances. On the other hand, the difficulty of manufacturing and assembling the anti-spray box 10 is relatively low.

[0078] Please refer to Fig.21 As shown, the first box body 1 may include a plurality of buckles 12, please refer to Fig. 22As shown, the second box body 2 may include a plurality of clamping holes 22. The first box body 1 and the second box body 2 are detachably connected by clamping the buckle 12 and the clamping hole 22.

[0079] In other embodiments (not shown in the figure), the first box body may also include a plurality of clamping holes, and the second box body may also include a plurality of buckles. The buckles and the clamping holes are clamped together to make the first box body and the second box body detachably connected.

[0080] In other embodiments (not shown in the figures), the first box body and the second box body may be connected magnetically, or the first box body and the second box body may be bonded, or the first box body and the second box body may be connected by fasteners such as bolts or screws.

[0081] In addition, the first box body 1 and the second box body 2 may be enclosed to form a first through hole 10a, the second box body 2 may be provided with a second through hole 10b, and the first box body 1 and the second box body 2 may be enclosed to form a receiving cavity 10c.

[0082] Optionally, see Fig. 20 As shown, the spray-proof liquid box 10 further includes a first door 3 and a second door 4. The first door 3 includes a first cover member 31 and a first toggle member 32 connected to each other, and the second door 4 includes a second cover member 41 and a second toggle member 42 connected to each other. By toggling the first toggle member 32 and the second toggle member 42, the spray-proof liquid box 10 can be placed in the following positions: Fig. 20 The first state shown or Fig.23 In the second state shown, in the first state, the first covering member 31 and the second covering member 41 cover the second through hole 10b, and in the second state, the first covering member 31 and the second covering member 41 do not cover the second through hole 10b.

[0083] When the branch connection piece is not connected to the corresponding liquid cooling piece, the spray liquid prevention box 10 can be placed in the first state. Even if the branch connection piece leaks liquid, the leaked liquid can be blocked in the spray liquid prevention box 10 by the first cover piece 31 and the second cover piece 41. The leaked liquid can be discharged to the spray liquid prevention box or the liquid collection tray located below through the liquid discharge structure of the spray liquid prevention box 10, thereby reducing the possibility that the leaked liquid is directly sprayed onto the electronic device through the second through hole 10b.

[0084] When the branch connector needs to be connected to the corresponding liquid cooling component, the spray prevention box 10 can be placed in the second state, and the liquid cooling interface of the liquid cooling component can enter the accommodating cavity 10c from the outside of the spray prevention box 10 through the second through hole 10b, thereby connecting the branch connector and the liquid cooling component.

[0085] Please refer to Fig. 22 As shown, the second box body 2 can be provided with two notches 23. One of the notches 23 is used to be penetrated by the first toggle member 32, and the other notch 23 is used to be penetrated by the second toggle member 42.

[0086] In addition, the first covering member 31 and the second covering member 41 can be rotatably connected to the first box body 1 and the second box body 2 . Also, please refer to Figure 21-22 As shown, at least one of the first box body 1 and the second box body 2 may be provided with a guide pin hole 10h, and the guide pin hole 10h is used to be penetrated by a guide pin of the liquid cooling pipeline structure so that the spray prevention box moves relative to the branch connector in a direction parallel to the direction X under the guidance of the guide pin.

[0087] In the second aspect, an embodiment of the present application provides a liquid cooling pipeline structure, which includes at least two spray liquid prevention boxes as described above, and at least two spray liquid prevention boxes are distributed along the height direction of the liquid cooling pipeline structure. The drainage structure of the spray liquid prevention box located at a higher position is used to discharge the liquid into the liquid inlet structure of the spray liquid prevention box located at a lower position. Compared with the liquid cooling pipeline structure in the above-mentioned related art, in the liquid cooling pipeline structure of the embodiment of the present application, since the structure of the spray liquid prevention box has the function of blocking the leaked liquid from being directly sprayed onto the electronic device, the drainage function of the drain pipe is also integrated. Therefore, the liquid cooling pipeline structure of the embodiment of the present application may not be provided with a drain pipe (for example, a drain pipe installed in the main pipe of the liquid cooling pipeline structure). On the one hand, the volume of the liquid cooling pipeline structure is relatively small, so that the internal space of the liquid cooling cabinet occupied by the liquid cooling pipeline structure is relatively small, and the volume of electronic equipment that can be stored in the liquid cooling cabinet is relatively large, or the volume of the liquid cooling cabinet can be relatively small; on the other hand, the structural complexity of the liquid cooling pipeline structure is relatively low, so that the difficulty of manufacturing, assembling and maintaining the liquid cooling pipeline structure are relatively small.

[0088] The liquid cooling pipeline structure of the embodiment of the present application also includes other technical effects described above regarding the spray prevention box, which will not be repeated here.

[0089] Please refer to Fig.24 As shown, the liquid cooling pipeline structure may include a main pipeline 20, at least two spray prevention boxes 10, at least two branch connection pieces 30, and at least two guide pins 40. At least two spray prevention boxes 10 are distributed along the height direction (direction Z), at least two branch connection pieces 30 are distributed along the height direction (direction Z), and at least two guide pins 40 are distributed along the height direction.

[0090] Please refer to Fig.24 As shown, the main line pipe 20 is connected to at least two branch connecting members 30, each branch connecting member 30 is used to be detachably connected to a corresponding liquid cooling member, and a joint in each branch connecting member 30 for connecting to the liquid cooling member can be located in a corresponding spray prevention box 10, and the main line pipe 20 is connected to at least two guide pins 40, and each spray prevention box 10 is penetrated by a corresponding guide pin 40.

[0091] Both the main pipe 20 and the branch connector 30 are used to circulate the coolant. When the liquid cooling pipeline structure acts as a liquid distributor, the main pipe 20 can distribute the coolant to each branch connector 30, and each branch connector 30 then introduces the branch flow of the coolant into the corresponding liquid cooling component (not shown in the figure). When the liquid cooling pipeline structure acts as a liquid collector, the main pipe 20 can collect the branch flows of the coolant in each liquid cooling component (not shown in the figure) through each branch connector 30.

[0092] Each spray-proof liquid box 10 can slide relative to the corresponding guide pin 40 in a direction parallel to the direction X, for example, Fig.24 and Fig.25 In the embodiment, the spray-proof liquid box 10 in the middle can be placed as follows Fig.24 The positions shown and Fig.25 When the spray-proof liquid box 10 located in the middle slides to Fig.25 In the position shown, the joint for connecting with the liquid cooling component (not shown in the figure) in the branch connector 30 corresponding to the spray liquid prevention box 10 in the middle is located outside the spray liquid prevention box 10, which is convenient for the user to observe and operate the joint for connecting with the liquid cooling component in the branch connector 30.

[0093] exist Fig.24 and Fig.25 In the embodiment, although the position of the spray-proof liquid box 10 in the middle is changed, the liquid discharge structure 21 of the spray-proof liquid box 10 in the upper part can also discharge the liquid into the spray-proof liquid box 10 in the middle, and the liquid discharge structure 21 of the spray-proof liquid box 10 in the middle can also discharge the liquid into the spray-proof liquid box 10 in the lower part. The relevant principles and effects have been described above and will not be repeated here.

[0094] In a third aspect, an embodiment of the present application provides a liquid cooling cabinet, which includes a cabinet body, a liquid distributor, a liquid collector, and at least two liquid cooling parts. The liquid distributor, the liquid collector, and the at least two liquid cooling parts can be detachably installed in the cabinet body. The liquid distributor is detachably connected to the at least two liquid cooling parts, and the liquid collector is detachably connected to the at least two liquid cooling parts. The liquid distributor and the liquid collector both use the liquid cooling pipeline structure described in the above content. Therefore, the liquid cooling cabinet also includes the technical effects of the liquid cooling pipeline structure in the above content, which will not be repeated here.

[0095] The external coolant can flow into the liquid cooling component through the liquid separator. After absorbing the heat of the electronic equipment, the coolant in the liquid cooling component flows into the external circuit through the liquid collector. After the coolant dissipates the heat in the external circuit, it flows back to the liquid separator, thereby completing the required heat dissipation cycle process.

[0096] The liquid distributor can distribute the cooling liquid to at least two liquid cooling components, each of which is used to cool a corresponding electronic device, and the liquid collector is used to collect the tributaries of the cooling liquid of the at least two liquid cooling components.

[0097] It can be seen from the above that the liquid cooling pipeline structure using the anti-spray liquid box provided in the embodiment of the present application can improve the problem of the liquid cooling pipeline structure occupying a large amount of internal space of the liquid cooling cabinet in the prior art.

[0098] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
