[0002] Energy storage system is the core technology in the field of energy utilization. It includes many electronic and electric equipment, which need to be cooled in time during operation. Most existing cooling systems are liquid cooling systems, with many liquid cooling pipes installed inside the equipment. The pipe joints are generally connected with rigid pipe joints. If there is an assembly error between the two pipes, or after long-term use, the connection between the pipe joints and the pipes is prone to failure, resulting in coolant leakage, which will seriously affect the reliability of the overall operation of the cooling system. Utility Model Content

[0003] The embodiments of the utility model provide a pipeline waterproof joint, a pipeline docking structure assembly and a liquid cooling system, aiming to solve the problem of easy sealing failure between the pipe joint and the pipe fitting in the existing cooling system.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] In a first aspect, an embodiment of the utility model provides a pipeline waterproof joint, comprising:

[0006] A first connecting cylinder, a connecting ring, and a second connecting cylinder connected in sequence along a preset path;

[0007] The first connecting tube is an elastic component and can be closely fitted with the outer peripheral surface of the first pipe;

[0008] The connecting ring is used to be fixedly connected to the device body;

[0009] The second connecting tube is an elastic component and can be tightly fitted with the outer circumferential surface of the second pipe.

[0010] In combination with the first aspect, in a possible implementation, the second connecting tube is a tapered tube, the large end of the second connecting tube is connected to the connecting ring, and the second connecting tube is plug-fitted with the second pipe fitting;

[0011] The wall surface of the second connecting tube facing its own central axis in the free state is the inner wall surface, and the wall surface of the second connecting tube facing away from its own central axis in the free state is the outer wall surface; after the second pipe fitting is plugged into the second connecting tube, the second connecting tube is folded inwardly toward the direction of the first connecting tube, and the outer wall surface is tightly fitted with the outer peripheral surface of the second pipe fitting.

[0012] In combination with the first aspect, in a possible implementation manner, the first connecting tube is a conical tube, and the large end of the first connecting tube is connected to the connecting ring.

[0013] In some embodiments, a plugging cover is provided at a port of the first connecting tube away from the connecting ring, and the plugging cover is detachably connected to the first connecting tube.

[0014] In some embodiments, a pulling piece is provided on a side of the plugging cover facing away from the connecting ring, the plugging cover and the first connecting tube are integrally formed, and a tear line is provided at a connection area between the plugging cover and the first connecting tube.

[0015] In some embodiments, at least one cutting convex mark is disposed on the outer circumference of the first connecting tube.

[0016] In some embodiments, the connecting ring includes an outer ring body and a supporting inner core, the supporting inner core is annular and is a rigid component, and the outer ring body is wrapped around the outer circumference of the supporting inner core; the outer ring body is an elastic component and is integrally connected to the first connecting tube and the second connecting tube respectively.

[0017] In some embodiments, the outer ring body is closely connected to the device body, and a sealing lip is provided on the side of the outer ring body facing the device body.

[0019] Since the first connecting tube and the second connecting tube are both elastic components, there are axial and radial deformable amounts. Even if there is an assembly error between the first pipe fitting and the second pipe fitting, the deformation between the first connecting tube and the second connecting tube can absorb this error. In addition, during use, even if the equipment shakes, resulting in shaking between the first pipe fitting and the second pipe fitting, between the first pipe fitting and the equipment body, and between the second pipe fitting and the equipment body, the elastic deformation capacity of the first connecting tube and the second connecting tube can also adapt to this deformation well. The first connecting tube always maintains a close fit with the first pipe fitting, and the second connecting tube always maintains a close fit with the second pipe fitting.

In addition, the first pipe fitting and the second pipe fitting may also produce assembly errors on the first path, or shake along the first path. The first connecting tube and the second connecting tube can also maintain a close fit with the first pipe fitting and the second pipe fitting due to their own elastic deformation capacity, while absorbing assembly errors or buffering shaking energy.

[0020] The pipeline waterproof joint of the present application has good sealing performance, can effectively absorb assembly errors, and can effectively maintain the sealing between the pipe fittings after long-term use, so the reliability and service life can be guaranteed.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] In the claims, specification and the above-mentioned drawings of the utility model, unless otherwise explicitly defined, directional words, such as the terms "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise", "high", "low", etc., indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific protection scope of the utility model.

[0037] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.

[0038] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0039] Please also read Figures 1 to 7 The pipe waterproof joint 1 provided by the utility model is now described. The pipe waterproof joint 1 comprises a first connecting tube 10, a connecting ring 20 and a second connecting tube 30 which are connected in sequence along a preset path; the first connecting tube 10 is an elastic component and can be closely fitted with the outer circumference of the first pipe 6; the connecting ring 20 is used for fixed connection with the equipment body 5; the second connecting tube 30 is an elastic component and can be closely fitted with the outer circumference of the second pipe 7.

[0040] In this embodiment, after the first connecting tube 10 is sleeved on the outer circumference of the first pipe 6, the first connecting tube 10 can be circumferentially pressed by the external auxiliary structure, so that the first connecting tube 10 always maintains a state of effective sealing and fitting with the first pipe 6. After the second connecting tube 30 is sleeved on the outer circumference of the second pipe 7, the second connecting tube 30 can be circumferentially pressed by the external auxiliary structure, so that the second connecting tube 30 always maintains a state of effective sealing and fitting with the second pipe 7. Of course, the external auxiliary structure may not be used between the first connecting tube 10 and the first pipe 6, and between the second connecting tube 30 and the second pipe 7, and this is not the only limitation here.

[0041] Compared with the prior art, the pipe waterproof joint 1 provided in this embodiment has mutually connected cavities formed inside the first connecting tube 10, the connecting ring 20 and the second connecting tube 30. The first connecting tube 10 is tightly fitted with the outer peripheral surface of the first pipe fitting 6 to achieve a sealed connection with the first pipe fitting 6; the connecting ring 20 is connected to the equipment body 5 to achieve relative fixation of the pipe waterproof joint 1 and the equipment body 5; the second connecting tube 30 is connected to the second pipe fitting 7 to achieve a sealed connection with the second pipe fitting 7.

[0042] Since the first connecting tube 10 and the second connecting tube 30 are both elastic components, there are axial and radial deformations, even if there is an assembly error between the first pipe 6 and the second pipe 7, the deformation between the first connecting tube 10 and the second connecting tube 30 can absorb this error. In addition, during use, even if the equipment shakes, causing shaking between the first pipe 6 and the second pipe 7, between the first pipe 6 and the equipment body 5, and between the second pipe 7 and the equipment body 5, the elastic deformation capacity of the first connecting tube 10 and the second connecting tube 30 can also adapt to this deformation well, the first connecting tube 10 always maintains a close fit with the first pipe 6, and the second connecting tube 30 always maintains a close fit with the second pipe 7, and after long-term use, the problem of connection failure between the first pipe 6 and the second pipe 7 can be avoided.

[0043] In addition, the first pipe fitting 6 and the second pipe fitting 7 may also produce assembly errors on the first path, or produce shaking along the first path. The first connecting tube 10 and the second connecting tube 30 can also maintain a close fit with the first pipe fitting 6 and the second pipe fitting 7 due to their own elastic deformation ability, while absorbing assembly errors or buffering shaking energy.

[0044] In general, the pipe waterproof joint 1 of this embodiment has good sealing performance, can effectively absorb assembly errors, and can effectively maintain the sealing between the pipe fittings after long-term use, so the reliability and service life can be guaranteed.

[0045] It should also be noted that even if a gap is formed between the first pipe fitting 6 and the second pipe fitting 7 due to the distance from each other or radial misalignment, the leaked coolant will be gathered in the cavity enclosed by the first connecting tube 10, the connecting ring 20 and the second connecting tube 30, and will not leak to other positions of the equipment body 5, so as to avoid affecting the operation of other components in other equipment bodies 5. If the first pipe fitting 6 and the second pipe fitting 7 can be re-joined and the gap between the two can be bridged, the amount of leaked coolant will be very small and will not affect the overall operation of the cooling system; if the gap between the first pipe fitting 6 and the second pipe fitting 7 exists for a long time, the cavity enclosed by the first connecting tube 10, the connecting ring 20 and the second connecting tube 30 can be used as a circulation space for the coolant, and the coolant therein can centrally participate in the cooling cycle, without waste and without affecting the overall operation of the cooling system.

[0046] In some embodiments, see Figures 1 to 7 The second connecting tube 30 is a tapered tube. The large end of the second connecting tube 30 is connected to the connecting ring 20. The second connecting tube 30 is plugged and matched with the second pipe 7. In the free state, the inner diameter of the small end of the second connecting tube 30 is smaller than the outer diameter of the first pipe 6, and the outer diameter of the small end is also smaller than the outer diameter of the first pipe 6. The wall surface of the second connecting tube 30 facing the central axis in the free state is the inner wall surface 301, and the wall surface of the second connecting tube 30 facing away from the central axis in the free state is the outer wall surface 302; the second pipe 7 is inserted from the small end of the second connecting tube 30, and is plugged and moved in the direction toward the large end of the second connecting tube 30. After the second pipe 7 is plugged with the second connecting tube 30, the second connecting tube 30 is folded and rolled inward toward the direction of the first connecting tube 10, and the outer wall surface 302 is tightly fitted with the outer peripheral surface of the second pipe 7.

[0047] In this embodiment, the first connecting tube 10 and the second connecting tube 30 cooperate to form a double-layer sealing effect by rolling up the second connecting tube 30, and the installation is convenient, and no additional connection structure is required between the second connecting tube 30 and the second pipe 7, the number of parts is small, the failure rate is low, and the maintenance cost is low. In addition, the tapered design can make the small end of the second connecting tube 30 fit more closely to the outer periphery of the second pipe 7, and at the same time, it does not interfere with the protruding part of the second pipe, and the assembly reliability is better.

[0048] Based on the above embodiments, see Figure 2 In the free state, the wall of the first connecting tube 10 is an inwardly concave arc wall. After the second connecting tube 30 is rolled up, its outer wall surface 302 can better fit with the outer peripheral surface of the second pipe 7.

[0049] In some embodiments, see Figures 1 to 7 , the first connecting tube 10 is a tapered tube, and the large end of the first connecting tube 10 is connected to the connecting ring 20. The tapered design can make the small end of the first connecting tube 10 fit more closely to the outer periphery of the first pipe 6, and at the same time, it does not interfere with the inserted part of the first pipe, and the assembly reliability is better. In this embodiment, the first pipe 6 is shown as a pipe end, and the pipe end is inserted into the small end of the first connecting tube 10. The connector 3 of the pipe body 2 is sleeved on the outer periphery of the first connecting tube 10 and the first pipe 6, and the first connecting tube 10 is pressed by the clamping ring 4, and the clamping ring 4 is also clamped into the clamping groove on the first pipe 6.

[0050] In specific implementation, the small end of the first connecting tube 10 is directly sleeved on the outer periphery of the first pipe 6 (such as Figures 5 to 7 or, the first connecting tube 10 is similar to the second connecting tube 30. After being pushed and rolled by the first pipe 6, the outer peripheral wall surface of the first connecting tube 10 is tightly fitted with the outer peripheral surface of the first pipe 6, which is not shown in the figure.

[0051] In some embodiments, see Figures 1 to 7 A plugging cover 40 is provided at one end of the first connecting tube 10 away from the connecting ring 20, and the plugging cover 40 is detachably connected to the first connecting tube 10. When the pipe waterproof joint 1 is transported as a part, the plugging cover 40 can seal the first connecting tube 10, and has a waterproof and dustproof effect to a certain extent, which reduces the cleaning steps of the pipe waterproof joint 1 during assembly, and the plugging cover 40 can be removed during assembly.

[0052] Based on the above embodiment, an auxiliary plugging cover 40 is also provided at a port of the second connecting tube 30 away from the connecting ring 20. The auxiliary plugging cover 40 is detachably connected to the second connecting tube 30 and plays a similar role to the aforementioned plugging cover 40, which will not be described again.

[0053] In some embodiments, in order to realize the detachable connection between the plug cover 40 and the first connecting tube 10, see Figures 1 to 7 A pulling member 50 is provided on the side of the plugging cover 40 away from the connecting ring 20. The plugging cover 40 is integrally formed with the first connecting tube 10, and a tear line 70 is provided at the connecting area between the plugging cover 40 and the first connecting tube 10. The pulling member 50 applies a pulling force to the plugging cover 40, and the edge of the plugging cover 40 is torn along the tear line 70, and finally the plugging cover 40 is removed as a whole.

[0054] In some specific embodiments of the easy-tear line 70, the easy-tear line 70 is formed when the first connecting tube 10 and the plugging cover 40 are formed, and is a weakened area between the two. Its specific structure is exemplified as follows: 1) The cross-sectional contour line of the connection area between the first connecting tube 10 and the plugging cover 40 is X-shaped, and the center thickness of the X-shape is the thinnest and the structural strength is the lowest. By applying a pulling force by the pulling member 50, the center position of the X-shape can be torn, and then the plugging cover 40 can be fallen off; 2) The connection area between the first connecting tube 10 and the plugging cover 40 is provided with slits and connecting parts alternately distributed along the circumference of the plugging cover 40. The size of the connecting part is very small and is relatively easy to break. The slit is in a wall-fitting and roughly closed state in a free state, which can meet the basic blocking requirements. By applying a pulling force by the pulling member 50, the connecting part can be broken, and then the plugging cover 40 can be fallen off.

[0055] Optionally, in order to achieve effective pulling, the pulling member 50 may be implemented in the following ways, but not limited to: a) the pulling member 50 is a pull ring, which is arranged in the middle of the plugging cover 40 or near the edge; b) the pulling member 50 is an arc-shaped sheet, which is arranged on the plugging cover 40 near its own edge; c) the pulling member 50 is a pull wire, one end of which is connected to the middle of the plugging cover 40 or near the edge. In this embodiment, the material of the pulling member 50 can be the same as that of the plugging cover 40, and the two are integrally formed by injection molding or other processes; or, the material of the pulling member 50 is different from that of the plugging cover 40, and the two are integrally connected by secondary injection molding or other processes.

[0056] In some embodiments, see Figures 1 to 3 The outer circumference of the first connecting tube 10 is provided with at least one cutting convex mark 60. For first pipes 6 of different sizes, it can be selected whether to cut along the cutting convex mark 60, so that the size of the port of the first connecting tube 10 away from the connecting ring 20 is adapted to the first pipe 6, and the use flexibility is stronger. In specific implementation, if there are multiple cutting convex marks 60, the multiple cutting convex marks 60 are spaced apart along the preset path.

[0057] In some embodiments, the connecting ring 20 may be formed as follows: Figures 2 to 7 In the structure shown, the connecting ring 20 includes an outer ring body 210 and a supporting inner core 220. The supporting inner core 220 is annular and is a rigid component. The outer ring body 210 is coated on the outer periphery of the supporting inner core 220. The outer ring body 210 is an elastic component and is integrally connected with the first connecting tube 10 and the second connecting tube 30. The outer ring body 210 can be tightly fitted and fixed with the equipment body 5, and can also avoid problems such as friction noise and knock noise. In addition, the material is the same or similar to that of the first connecting tube 10 and the second connecting tube 30, and the first connecting tube 10, the second connecting tube 30, the outer ring body 210 and the supporting inner core 220 can be integrally connected by secondary injection molding, which has good structural stability and low manufacturing cost.

[0058] In some embodiments, see Figure 3 and Figure 4 The outer peripheral contour of the connecting ring 20 is polygonal, and mounting holes 201 are respectively arranged near each corner on the connecting ring 20. The penetration direction of the mounting holes 201 is parallel to the preset path. The connecting ring 20 is fixedly connected to the device body 5 by fasteners (such as threaded fasteners) penetrating the mounting holes 201. Among them, the supporting inner core 220 extends to a position close to the edge of the outer ring body 210, covering the area where the mounting holes 201 are located, and the mounting holes 201 penetrate the outer ring body 210 and the supporting inner core 220 at the same time.

[0059] In some embodiments, see Figures 2 to 7The outer ring body 210 is closely connected with the device body 5, and a sealing lip 230 is provided on the outer ring body 210 facing the device body 5. The sealing lip 230 is used to achieve sealing with the device body 5, thereby avoiding the problem of liquid leakage between the connecting ring 20 and the device body 5.

[0060] In some specific embodiments, see Figures 2 to 7 The sealing lip 230 is coaxially arranged with multiple circles about the central axis of the connecting ring 20, and the outermost circle of the sealing lip 230 is located at the edge of the connecting ring 20. In a specific implementation, the cross section of the sealing lip 230 is wedge-shaped, and in a free state, the outer side surface of the sealing lip 230 is parallel to the preset path, and the inner side surface is inclined outward in a direction away from the connecting ring 20.

[0061] For more details, see Figure 4 , an auxiliary lip 240 is provided on the periphery of the mounting via 201, which can seal the periphery of the mounting via 201. In specific implementation, the mounting via 201 is located inside the innermost sealing lip 230, the auxiliary lip 240 is provided around the mounting via 201, and both ends of the auxiliary lip 240 are respectively connected to the innermost sealing lip 230 as a whole, and the periphery of the mounting via 201 is sealed by the cooperation between the sealing lip 230 and the auxiliary lip 240, which simplifies the lip setting method to the greatest extent and ensures the sealing effect.

[0062] Based on the same inventive concept, the present application embodiment further provides a pipeline docking structure assembly, see Figures 5 to 7 The pipeline docking structure assembly includes a first pipe fitting 6, a second pipe fitting 7 and the above-mentioned pipeline waterproof joint 1, the first connecting tube 10 is tightly fitted with the outer circumference of the first pipe fitting 6, and the second connecting tube 30 is tightly fitted with the outer circumference of the second pipe fitting 7.

[0063] Compared with the prior art, the pipe docking structure assembly provided in this embodiment improves the sealing reliability of the pipe docking area by adopting the above-mentioned pipe waterproof joint 1, thereby ensuring the reliability of the overall operation of the cooling system.

[0064] For specific implementation, see Figures 5 to 7In a free state, the inner diameter of the end of the first connecting tube 10 facing the connecting ring 20, the inner diameter of the connecting ring 20, and the inner diameter of the large end of the second connecting tube 30 are the same, the first pipe fitting 6 and the second pipe fitting 7 are butt-jointed in the corresponding area of ​​the connecting ring 20, and the inner diameter of the connecting ring 20 is larger than the outer diameter of the first pipe fitting 6 and also larger than the outer diameter of the second pipe fitting 7, allowing the first pipe fitting 6 and the second pipe fitting 7 to be displaced or misaligned to a certain extent on the radial surface of the connecting ring 20. In the ideal docking state, the first pipe fitting 6 and the second pipe fitting 7 are coaxial, and the end faces of the two are tightly abutted; in the actual assembly process, there may be an assembly error between the first pipe fitting 6 and the second pipe fitting 7, resulting in the first pipe fitting 6 and the second pipe fitting 7 not being coaxial, or, during use, the electronic power equipment will generate vibrations, which are transmitted to the first pipe fitting 6 and the second pipe fitting 7, and the first pipe fitting 6 and the second pipe fitting 7 will shake relative to the equipment body 5, and the shaking between the first pipe fitting 6 and the second pipe fitting 7 will also be asynchronous. Under the premise that the first connecting tube 10 and the second connecting tube 30 are both elastic components, the first connecting tube 10 and the second connecting tube 30 can always maintain a close fit with the corresponding pipe fittings to avoid leakage. In fact, the pipe waterproof joint 1 ensures the reliability of the seal, and can also absorb assembly errors and effectively adapt to the shaking of the pipe fittings.

[0065] Based on the same inventive concept, an embodiment of the present application also provides a liquid cooling system, including the above-mentioned pipe docking structure assembly.

[0066] Compared with the prior art, the liquid cooling system provided in this embodiment effectively extends the sealing reliability and service life of adjacent pipes by adopting the above-mentioned pipe docking structure assembly, and effectively improves the stability and reliability of the overall operation of the cooling system.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
