[0002] Liquid cooling systems, as highly efficient heat dissipation solutions, are widely used in data centers, electronic equipment, automobiles, aerospace, and other fields. Liquid cooling pipe joints, as key components connecting cooling pipes and cooling devices, have a direct impact on the system's heat dissipation efficiency, reliability, and installation and maintenance costs.

[0003] Currently, common liquid cooling pipe joints are typically connected using welding. While welding offers a certain degree of sealing reliability, it presents challenges such as complex installation processes, high operator requirements, and limited construction environments. This increases overall manufacturing and installation costs, hindering large-scale application. Furthermore, due to structural size limitations, the riveted ends of existing liquid cooling pipe joints often occupy a significant amount of space, resulting in significant head loss during fluid flow, impacting the fluid efficiency of the liquid cooling system.

[0004] In order to solve the above problems, there is an urgent need for a liquid cooling pipe joint that has a simpler installation process, a more compact structure, reliable connection strength and can effectively reduce head loss. Summary of the Invention

[0007] A through hole penetrating to the rivet part is formed on the end surface of the main body away from the flange part, and the rivet part has a rivet thread that can be connected to a rivet tool.

[0012] Furthermore, the outer diameter of the rivet portion is smaller than or equal to the outer diameter of the deformation portion.

[0013] Furthermore, the wall thickness of the connecting portion is smaller than the wall thickness of the deforming portion.

Under the action of the riveting tool, the riveting part is broken between the riveting part and the deforming part, and at least part of the deforming part is deformed by riveting under the action of the riveting part to become a deformation unit. The deformation unit and the flange part clamp the plate of the tubular profile with the mounting hole, so that the liquid-cooling pipe joint is riveted to the tubular profile.

[0019] Furthermore, a limiting portion is provided at the connection between the flange portion and the deformation portion, and a limiting hole cooperating with the limiting portion is provided on the end surface of the tubular profile.

[0020] Furthermore, a sealing groove surrounding the deformation portion is formed on a side of the flange portion facing away from the main body, and the sealing groove is used to accommodate a sealing ring, and the flange portion and the end surface of the tubular profile press the sealing ring tightly.

[0021] The present invention also discloses a method for using a low-head-loss liquid-cooling pipe joint, comprising the following steps:

The rivet tool continues to pull the rivet part and moves it toward the flange part. The rivet part abuts against the deformed part, so that the deformed part is plastically deformed to become a deformed unit riveted to the tubular profile.

[0027] In step five, the rivet tool continues to pull the rivet part until the rivet part is broken and separated from the deformation unit, the rivet tool rotates and separates from the rivet part so that the rivet part falls off, and the rivet part is taken out from the outlet in the length direction of the tubular profile.

[0048] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0049] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0050] like Figures 1 to 9 As shown, the present invention discloses a low head loss liquid cooling pipe joint, comprising a flange portion 2 and a body 1 and a deforming portion 3 coaxially arranged on both sides of the flange portion 2. The deforming portion 3 further comprises a rivet portion 5 at one end away from the flange portion 2. The deforming portion 3 is breakably connected to the rivet portion 5 via a connecting portion 4.

[0051] A through hole penetrating to the rivet portion 5 is formed on the end surface of the main body 1 facing away from the flange portion 2 , and a rivet thread 51 capable of being connected to a rivet tool 6 is formed on the inner wall of the rivet portion 5 .

[0052] The liquid-cooling pipe joint of the present invention is suitable for coolants with temperatures ranging from -40°C to 150°C. Since the liquid-cooling pipe joint has a flange portion 2 and a deforming portion 3, with the deforming portion 3 disposed on one side of the flange portion 2, during use, the liquid-cooling pipe joint passes through the plate to be connected, and the end face of the flange portion 2 facing the deforming portion 3 abuts against the end face of the plate. The rivet tool 6 is connected to the rivet portion 5 via the rivet thread 51 and applies axial tension thereto, causing the rivet portion 5 to move toward the body 1, thereby deforming the deforming portion 3 and riveting the liquid-cooling pipe joint to the plate.

[0053] The main body 1 is provided with a through-hole on the end face away from the flange portion 2, extending axially through the rivet portion 5 to form a liquid flow channel. The deformed portion 3 is connected to the rivet portion 5 via a connecting portion 4, so that during the riveting process, the deformed portion 3 and the rivet portion 5 are separated by the rivet force. This ensures that the riveted end of the liquid cooling pipe joint can be kept small. There is no significant flow resistance when liquid flows from the main body 1, effectively reducing head loss during liquid flow, improving the cooling efficiency of the liquid cooling system, and thus achieving a low-head-loss flow effect.

[0054] Preferably, a sealing groove 21 surrounding the deformed portion 3 is formed on the side of the flange 2 facing away from the body 1. The sealing groove 21 accommodates an O-shaped sealing ring 22 to enhance the sealing performance of the liquid-cooling pipe joint. During installation, the sealing ring 22 is positioned between the flange 2 and the plate. The flange 2 presses the sealing ring 22 against the plate, while the sealing ring 22 also clings to the deformed portion 3 and the plate, thereby forming an effective liquid isolation structure, preventing liquid leakage and achieving a good sealing effect.

[0055] In this embodiment, Figure 1 As shown, a limiting portion 23 is provided at the connection between the flange portion 2 and the deformation portion 3. The limiting portion 23 can cooperate with the limiting hole on the plate to be connected, and is used to limit the rotation of the liquid cooling pipe joint to prevent the deformation portion 3 from offsetting or rotating when subjected to force, thereby ensuring the stability of the riveting operation.

[0056] Furthermore, the stopper 23 is a polygonal structure coaxially arranged with the flange 2, and may be hexagonal or octagonal, thereby achieving a rotational locking function for the liquid cooling pipe joint. During riveting or water pipe connection, the polygonal stopper 23 prevents the liquid cooling pipe joint from rotating with the riveting tool 6 or the water pipe, effectively avoiding thread slippage or assembly errors caused by rotation.

[0057] In this embodiment, the inner wall of the body 1 is provided with an internal thread 11, the diameter of which is larger than the diameter of the rivet thread 51. During riveting, the rivet tool 6 extends from the through-hole of the body 1 into the rivet portion 5, ensuring that the internal thread 11 on the inner wall of the body 1 does not interfere with the rivet tool 6. As a result, the rivet tool 6 can smoothly connect with the rivet thread 51 on the inner wall of the rivet portion 5, and apply axial tension to the rivet portion 5, causing the deformable portion 3 to deform, thereby riveting the liquid cooling pipe joint to the plate. When the liquid cooling pipe joint is in use, the water pipe is connected to the internal thread 11 of the body 1, ensuring a continuous water flow path between the body 1 and the water pipe.

[0058] like Figure 1 and Figure 2 As shown, in this embodiment, the outer diameter of the rivet portion 5 is smaller than the outer diameter of the deformable portion 3. Therefore, when installing, the rivet portion 5 can more easily enter the corresponding mounting hole of the plate, and can also provide a control area for the deformation portion 3 to break. The rivet portion 5 and the deformation portion 3 can form a step difference in size, so that the deformation portion 3 can focus stress on the preset connection portion 4 during the riveting process, so that the rivet portion 5 can move toward the main body 1 and deform, cooperating with the flange portion 2 to clamp the plate. Alternatively, in another embodiment, the outer diameter of the rivet portion 5 can be at least equal to the outer diameter of the deformable portion 3. When the rivet portion 5 applies axial tension to the deformable portion 3, after the connection portion 4 breaks, the rivet portion 5 can abut against the deformable portion 3, thereby causing the deformable portion 3 to bulge and deform.

[0059] Furthermore, the wall thickness of the connecting portion 4 is smaller than the wall thickness of the deformed portion 3. During the riveting operation, the deformed portion 3 is deformed first. As the riveting tool 6 continues to pull back, a greater riveting force is applied, causing the connecting portion 4 to be sheared or torsionally sheared until the connecting portion 4 is broken and separated from the deformed portion 3.

[0060] Combine Figures 1 to 9 As shown, the present invention also discloses a connection structure of a liquid cooling pipe joint with low head loss, comprising:

[0061] The tubular profile 7 is a hollow structure with mounting holes formed thereon for riveting the liquid cooling pipe joints;

[0062] A liquid cooling pipe joint, comprising a flange portion 2, a body 1 coaxially arranged on both sides of the flange portion 2, and a deformable portion 3 at least partially capable of being deformed into a deformable unit 31. The deformable portion 3 further comprises a rivet portion 5 at one end facing away from the flange portion 2. The deformable portion 3 is breakably connected to the rivet portion 5 via a connecting portion 4.

[0063] The main body 1 is provided with a through hole extending through the rivet portion 5 , and the rivet portion 5 has a rivet thread 51 that can be connected to a rivet tool 6 ;

[0064] The liquid-cooling pipe joint passes through the mounting hole of the tubular profile 7. Under the action of the rivet tool 6, the rivet part 5 is broken between the rivet part 5 and the deformation part 3, and at least part of the deformation part 3 is deformed into a deformation unit 31 under the action of the rivet part 5. The deformation unit 31 and the flange part 2 clamp the plate of the tubular profile 7 with the mounting hole, so that the liquid-cooling pipe joint is riveted to the tubular profile 7, and the rivet part 5 is broken and separated from the deformed deformation unit 31, thereby reducing the head loss.

[0065] The connection structure provided by the present invention includes a tubular profile 7 and a liquid-cooling pipe joint. The body 1 of the liquid-cooling pipe joint is provided with a through-hole extending from the body 1 to the rivet portion 5, forming a communication path for liquid flow. The inner wall of the rivet portion 5 is provided with rivet threads 51 for threaded connection with a rivet tool 6. During use, the end of the liquid-cooling pipe joint with the deformable portion 3 is inserted into the mounting hole of the tubular profile 7. The rivet tool 6 is threadedly connected to the rivet portion 5 and applies axial tension to it, causing the rivet portion 5 to move relative to the body 1. This axial tension causes the deformable portion 3 to bulge and deform toward the flange portion 2, forming a deformation unit 31.

[0066] Specifically, the deformed deformation unit 31 and flange portion 2 are positioned on either side of the tubular profile 7, where the mounting hole is located. This effectively clamps the tubular profile 7 and secures the profile by riveting. After riveting, the riveted portion 5 and the deformation unit 31 can be broken and separated, allowing the riveted portion 5 to fall off. No protruding components remain within the tubular profile 7 after riveting, significantly reducing resistance to liquid flow and achieving low head loss.

[0067] After the deformation portion 3 is deformed, the deformation unit 31 is riveted and fixed to the tubular profile 7, thereby completing the riveting of the liquid cooling pipe joint. The size of the tail end can be reduced, thereby minimizing the head loss.

[0068] Furthermore, in order to ensure that the installation position is accurate and reliable, a limiting portion 23 is provided at the connection between the flange portion 2 and the deformation portion 3.

[0069] Correspondingly, a limiting hole is provided on the end surface of the tubular profile 7. The limiting structure not only plays the role of assembly positioning, but also prevents the joint from rotating or displacing due to vibration or water flow impact during use, thereby improving the stability and reliability of the connection.

[0070] Preferably, an annular sealing groove 21 is formed on one side of the flange portion 2 near the deformable portion 3. The sealing groove 21 can accommodate an O-shaped sealing ring 22. After the riveting connection is completed, the flange portion 2 and the end surface of the tubular profile 7 are axially compressed, and the sealing ring 22 is compressed, thereby forming an effective seal around the mounting hole to prevent liquid leakage.

[0071] like Figure 4 、 Figure 5 、 Figure 6 and Figure 9 As shown, the present invention also discloses a method for using a low head loss liquid cooling pipe joint, comprising the following steps:

[0072] Step 1: Provide a liquid cooling pipe joint, comprising a flange portion 2 and a body 1 and a deforming portion 3 coaxially arranged on both sides of the flange portion 2. The deforming portion 3 further comprises a rivet portion 5 at one end facing away from the flange portion 2. The deforming portion 3 is breakably connected to the rivet portion 5 via a connecting portion 4. After the deforming portion 3 and the rivet portion 5 are broken, the rivet portion 5 can abut against the deforming portion 3, thereby causing the deforming portion 3 to bulge and deform.

[0073] The end surface of the main body 1 facing away from the flange portion 2 is provided with a through hole penetrating to the rivet portion 5 , and the inner wall of the rivet portion 5 is provided with a rivet thread 51 that can be connected to a rivet tool 6 ;

[0074] Step 2: providing a tubular profile 7, wherein the tubular profile 7 has a mounting hole for riveting the liquid cooling pipe joint;

[0075] Step 3: One end of the liquid cooling pipe joint having the rivet portion 5 is inserted into the mounting hole, and the flange portion 2 is in close contact with the end surface of the tubular profile 7 having the mounting hole;

[0076] Step 4: Use a rivet tool 6 to connect with the rivet part 5 and pull the rivet part 5 to break the rivet part 5 and the deformed part 3. The rivet tool 6 continues to pull the rivet part 5 and move it toward the flange part 2. The rivet part 5 abuts against the deformed part 3, causing the deformed part 3 to undergo plastic deformation and become a deformed unit 31 riveted to the tubular profile 7.

[0077] Step 5: The rivet tool 6 rotates and separates from the rivet part 5 so that the rivet part 5 falls off.

[0078] Preferably, step three also includes that a sealing groove 21 surrounding the deformation portion 3 is opened on the side of the flange portion 2 facing away from the main body 1, and the sealing groove 21 is used to accommodate a sealing ring 22, and the flange portion 2 and the tubular profile 7 form an end face with a mounting hole to press the sealing ring 22.

[0079] Preferably, step three also includes providing a limiting portion 23 at the connection between the flange portion 2 and the deformation portion 3 , and providing a limiting hole on the end surface of the tubular profile 7 that cooperates with the limiting portion 23 .

[0080] like Figures 7 to 9As shown, the present invention also discloses a method for using a low head loss liquid cooling pipe joint, comprising the following steps:

[0081] Step 1: Provide a liquid cooling pipe joint, comprising a flange portion 2, a body 1 and a deformable portion 3 coaxially disposed on both sides of the flange portion, wherein the deformable portion 3 further comprises a rivet portion 5 at one end facing away from the flange portion 2, and the deformable portion 3 is breakably connected to the rivet portion 5 via a connecting portion 4;

[0082] The end surface of the main body 1 facing away from the flange portion 2 is provided with a through hole penetrating to the rivet portion 5 , and the inner wall of the rivet portion 5 is provided with a rivet thread 51 that can be connected to a rivet tool 6 ;

[0083] Step 2: providing a tubular profile 7, wherein the tubular profile 7 has a mounting hole for riveting the liquid cooling pipe joint;

[0084] Step 3: One end of the liquid cooling pipe joint having the rivet portion 5 is inserted into the mounting hole, and the flange portion 2 is in close contact with the end surface of the tubular profile 7 having the mounting hole;

[0085] Step 4: Use a rivet tool 6 to connect with the rivet part 5 and pull the rivet part 5 toward the flange part 2, so that the deformed part 3 undergoes plastic deformation. At least a portion of the deformed part 3 is deformed into a deformed unit 31 riveted to the tubular profile 7.

[0086] In step five, the rivet tool 6 continues to pull the rivet part 5 until the rivet part 5 is broken and separated from the deformation unit 31 , and the rivet tool 6 rotates and separates from the rivet part 5 so that the rivet part 5 falls off.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
