Description

Technical Field

[0001] The present invention relates to a connector, and more particularly to a joint for all - liquid cooling. Background Art

[0002] The description in this part only provides background information related to the disclosure of the present invention and does not constitute prior art.

[0003] Currently, it is necessary to install a joint on a closed pipe workpiece to achieve liquid - cooling connection. Therefore, high requirements are imposed on the sealing performance and the fluidity of the liquid. In the prior art, generally the following two methods are used for connection:

[0004] The first one is to use mechanical connection methods such as welding, bonding, screwing, interference fit, etc. to achieve the connection between the joint and the closed pipe workpiece. Among them, some methods need to rely on sealing media and sealing rings. Therefore, the production efficiency is low, the quality control is difficult, the skill requirements for operators are high, and the consistency of the connection quality is poor.

[0005] The second one is to use the design and connection principle of blind rivet nuts to achieve the connection between the joint and the closed pipe workpiece. However, after blind riveting, the size of the joint protrusion remaining inside the closed pipe is large, and this joint protrusion will seriously reduce the heat - exchange efficiency of the coolant and increase the liquid resistance of the coolant. For liquid - cooling systems such as data centers and servers, the heat - exchange efficiency and the liquid resistance of the coolant are very critical indicators. In addition, the above - mentioned blind riveting method is difficult to apply to metal pipes with small cross - sectional sizes.

[0049] See also Figure 1-2 , is a full liquid cooling joint of this embodiment, used for riveting with a workpiece 2, wherein the workpiece 2 has a riveting hole, wherein the joint 1 comprises:

[0050] A riveting portion 13, the riveting portion 13 is used to be installed in the riveting hole, and the inner wall of the riveting portion 13 is set to be a smooth wall surface;

[0051] A flange portion 11, the flange portion 11 is connected to the riveted portion 13, and one end surface of the flange portion 11 facing the riveted portion 13 is used to abut against the outer wall of the workpiece 2;

[0052] The mounting portion 14 is connected to the flange portion 11 and is disposed on a side of the flange portion 11 away from the riveted portion 13. The mounting portion 14 further includes a connecting mechanism 141, which is used to connect to an external pipeline;

[0053] The riveting portion 13 has a preset axial length, so that the riveting portion 13 can be riveted on the inner wall surface of the riveting hole of the workpiece 2 after being deformed radially outward;

[0054] The joint 1 has a lumen penetrating the riveted portion 13 , the flange portion 11 , and the mounting portion 14 .

[0055] With the above structure, when riveting is required, firstly, the riveting portion 13 of the joint 1 is inserted along the riveting hole position of the workpiece 2, so that most of the riveting portion 13 is inserted into the workpiece 2 along the direction of the workpiece 2 and protrudes inward along the inner wall of the workpiece 2. At the same time, the mounting portion 14 of the joint 1 is pressed and abutted against the outer wall surface of the workpiece 2. Then, asFigure 3 As shown, an external riveting tool is inserted vertically downward through the lumen of the joint 1. After being in place, the end head of the riveting tool abuts against the riveting portion 13 of the joint 1, and the riveting tool is activated to expand radially outward, causing the metal of the riveting portion 13 to deform under the radially outward acting force and gradually turn outward. At this time, the riveting portion 13 undergoes a transformation from its original state until the riveting portion 13 is completely turned outward and riveted into the inner wall of the workpiece 2, forming a riveted and fixed relationship between the joint 1 and the workpiece 2. Then, the riveting tool can be retracted and taken out from the lumen upward, completing all the riveting operations. Figures 1 to 2 When connecting an external pipeline, a pipeline head with corresponding dimensions that matches the connection mechanism 141 of the installation portion 14 is provided and inserted into each other, forming a tight connection between the pipeline and the installation portion 14. Thus, the sealed connection among the workpiece 2, the joint 1, and the external pipeline is completed. After passing the sealing test, the coolant can be filled in.

[0056] Specifically, please refer to

[0057] Specifically, please refer to Figure 1 , the connection mechanism 141 is set as an external thread provided on the outer wall of the installation portion 14, and the pipeline head of the pipeline can be an internal thread that matches the connection mechanism 141. A tight thread connection is formed between the internal thread and the external thread.

[0058] Please refer to Figure 3 , the connection mechanism 141 can also be set as an internal thread provided on the inner wall of the installation portion 14, and the pipeline head of the pipeline can be an external thread that matches the connection mechanism 141. A tight thread connection is formed between the internal thread and the external thread.

[0059] Please refer to Figure 4 , the connection mechanism 141 can also be set as an annular structure that protrudes radially outward along the outer wall of the installation portion 14, and the pipeline head of the pipeline can be a flexible hose with a certain elasticity. The flexible hose is sleeved on the outwardly protruding annular structure, forming a tight elastic seal connection.

[0060] Based on the structure of the above embodiment, it is riveted at the riveting hole of the workpiece 2 through the deformable riveting portion 13, and the connection mechanism 141 on the outer wall of the installation portion 14 is convenient for installation and has good sealing performance. Specifically, the joint 1 has a through lumen. A riveting tool inserted into the lumen of the joint 1 can drive the riveting portion 13 to turn outwards by means of the expansion at the head position. After the riveting portion 13 is deformed by turning outwards along the radial direction, it can be riveted on the inner wall surface of the riveting hole of the workpiece 2, so as to realize the riveting and fixing between the joint 1 and the workpiece 2. After riveting, the protrusion of the riveting portion 13 into the workpiece 2 is extremely small, and the resistance to liquid flow is small. Compared with the general riveting joint with a larger protrusion, it helps to improve the liquid cooling effect. Moreover, compared with the general mechanical connection methods such as welding, bonding, screwing, and interference fit, its riveting installation is simple, has high consistency, and good sealing performance. The connection mechanism 141 on the outer wall can be hermetically fixed to the external pipeline only by means of threaded connection or snap connection, etc., with high connection efficiency and good sealing effect.

[0061] The inner wall of the riveting portion 13 is set as a smooth wall surface, which is only used to cooperate with the riveting tool for the outward turning deformation during riveting. Compared with the traditional riveting structure that needs to set an internal thread to fix with the riveting tool and is riveted by the riveting mechanism, the riveting portion 13 in this embodiment is easy to process and has a small protruding size after outward turning riveting.

[0062] In this embodiment, the workpiece 2 is set as a pipe with a closed cross-section, and its inner wall has a chamber for liquid flow. Multiple riveting holes can be opened on the workpiece 2 as needed. The structure where the riveting holes are opened on the workpiece 2 is straight and has a flat surface.

[0063] In the case of the workpiece 2 of the metal pipe with a closed cross-section in this embodiment, during the riveting process, only the riveting portion 13 of the corresponding joint 1 needs to be passed through the riveting hole and turned up after riveting. Compared with the existing riveting method, there is no need to apply too much upward pulling force to the workpiece 2 of the metal pipe with a closed cross-section. Therefore, the material strength requirement for the workpiece 2 in this embodiment is not high, the wall thickness can be made thinner, and the thickness can be set between 0.5 mm and 5.0 mm, with a wider application range.

[0064] Before riveting, the joint 1 generally presents a flange portion 11 with radial expansion in the middle and a pipeline structure that uniformly penetrates up and down at both ends. Considering that it is necessary to make the protrusion inside the workpiece 2 smaller and the resistance to water smaller after riveting, the preset axial length of the riveting portion 13 before riveting can be set to be only slightly longer than the actual thickness of the workpiece 2. Specifically, the axial length of the riveting portion 13 is about 2 to 5 times the actual thickness of the workpiece 2.

[0065] Therefore, please refer to Figure 2, after the deformation of the riveting part 13, the riveting part 13 is completely turned outwards, and most of the outer wall of the riveting part 13 abuts against and is riveted to the inner wall of the workpiece 2. The length of the part where the riveting part 13 is bent and abuts against and is riveted to the inner wall of the workpiece 2 is equivalent to the length of the contact between the riveting part 13 and the inner hole wall of the riveting hole of the workpiece 2. Therefore, the riveting strength of the riveting part 13 can be effectively guaranteed.

[0066] In this embodiment, the radial dimension of the riveting part 13 is exactly the same as the aperture of the riveting hole of the workpiece 2. Therefore, a high tightness can be provided by the close fit between the riveting part 13 and the workpiece 2.

[0067] In this embodiment, the flange part 11 has a sufficiently large radial dimension. Preferably, the radial dimension of the flange part 11 is at least larger than that of the riveting part 13 after riveting, so that before riveting, the bottom end surface of the flange part 11 can effectively press the outer wall surface of the workpiece 2, and after riveting, the flange part 11 can clamp the thin wall of the workpiece 2 up and down in cooperation with the riveting part 13, achieving better tightness and riveting strength.

[0068] Most importantly, after the blind riveting of this embodiment, the riveting part 13 of the joint 1 is a single-layer metal thin wall that is turned outwards and closely fits onto the workpiece 2. The dimension of the riveting part 13 of the joint 1 protruding from the inner wall of the workpiece 2 is extremely small, and one side after riveting is almost flush with the inner wall of the workpiece 2, reducing the water resistance inside its channel. In addition, the wall thickness of the workpiece 2 can be made thinner, and the overall cost control of the product is better, making it easy to achieve miniaturization.

[0069] The following are several embodiments that can improve the riveting performance or sealing performance:

[0070] Embodiment 1

[0071] Please refer to Figure 1 、 2 , the riveting part 13 has a deformation seam 15 that opens towards the end face direction of the riveting part 13. The deformation seam 15 extends axially, and the deformation seam 15 penetrates through the riveting part 13 axially. The number of the deformation seams 15 is multiple, and the multiple deformation seams 15 are arranged at equal angles around the axis on the riveting part 13. Preferably, two deformation seams 15 that are spaced 180 degrees apart and penetrate through the entire riveting part 13 axially are provided in this embodiment. Specifically, the thickness of the deformation seam 15 is equivalent to the wall thickness of the material of the riveting part 13, so that the resistance during the deformation process of the riveting part 13 is smaller and smoother, and less metal tearing and irregular deformation occur at the position of the riveting part 13. Specifically, the main purpose of setting the deformation seam 15 is to make the material of the riveting part 13 more likely to deform itself during the process that the riveting part 13 is abutted and turned outwards by the blind riveting tool from the inside outwards. Therefore, during the riveting process, when the riveting part 13 undergoes the deformation of turning outwards, such as Figure 2As shown, deformation also occurred at the expansion joint 15, with a greater tendency for the metals of the riveted parts 13 on both sides of the expansion joint 15 to separate from each other, thereby buffering the irregular deformation or even tearing of the riveted part 13 during riveting deformation.

[0072] Embodiment 2

[0073] As Figure 1 shown, a sealing ring 12 is provided between the end face of the flange part 11 facing the workpiece and the outer wall of the workpiece 2. The sealing ring 12 is arranged along the radial direction adjacent to the edge position of the riveting hole. The sealing ring 12 can effectively improve the sealing performance between the end face of the flange part 11 facing the workpiece and the outer wall of the workpiece 2. And when the sealing ring 12 is arranged to fit the edge of the riveting hole, the sealing ring 12 can also at least partially contact the outer wall of the riveted part 13. Therefore, at this time, the sealing ring 12 has the largest contact coverage area with the gap between the external metals and can fill the gap, making the sealing effect better.

[0074] Embodiment 3

[0075] As Figure 1 shown, a connecting part 16 is further included between the flange part 11 and the mounting part 14, and the pipe cavity penetrates through the connecting part 16. The function of the connecting part 16 is that there is a conduit structure with an extended distance between the flange part 11 and the connecting mechanism 141, which can enable at least the liquid to have at least one extended and stable liquid path after entering the joint 1 from the workpiece 2 or before flowing from the joint 1 into the workpiece 2, reducing the resistance of the liquid and enabling the liquid to be continuously and stably exchanged between the joint 1 and the workpiece 2. Specifically, during the manufacturing stage, the connecting part 16 and the mounting part 14 are actually integrated, and the connecting mechanism 141 is extruded in the last step additionally, reducing the manufacturing cost. Under preferred conditions, the mounting part 14 and the connecting part 16 with the same axial length can maintain a stable structural strength under the integrated structure of the mounting part 14 and the connecting part 16.

[0076] Please refer to Figures 6-9 , which is a specific embodiment of riveting the joint of the present invention with a riveting tool.

[0077] Among them, the riveting tool includes a baffle 3;

[0078] a mandrel 4, and the first end of the mandrel 4 passes through the baffle 3;

[0079] a riveting mechanism 5, the riveting mechanism 5 includes a sleeve 51 and an elastic element 52. The sleeve 51 is sleeved on the mandrel 4. The first end of the sleeve 51 abuts against the baffle 3. The second end of the sleeve 51 is connected to the first end of the elastic element 52. At least part of the elastic element 52 is used to pass through the pipe cavity, and the outer wall of the second end of the elastic element 52 is used to abut against the inner wall of the second end of the joint 1;

[0080] The bulging element 6 is arranged at the second end of the mandrel 4;

[0081] Wherein, the elastic element 52 is used for when the bulging element 6 moves from the second end to the first end, the inner wall of the second end of the elastic element 52 abuts against the outer wall of the bulging element 6, and after the abutment, the elastic element 52 turns outwards, so that the outer wall of the elastic element 52 turns outwards the second end of the joint 1.

[0082] With the above structure, during use, first, the second end of the joint 1 is inserted into the riveting hole of the workpiece 2; so that at least part of the second end of the joint 1 penetrates through the side where the inner wall of the workpiece 2 is located; then, the riveting tool for connecting the liquid-cooled joint is inserted into the lumen of the joint 1, and the bulging element 6 protrudes from the second end of the lumen; the bulging element 6 extends out of the joint 1 and is arranged on one side of the inner wall of the workpiece 2; then, the mandrel 4 is pulled in the direction from the second end to the first end, so that the mandrel 4 drives the bulging element 6 to move, and turns outwards the elastic element 52 of the riveting mechanism 5, so that the second end of the joint 1 turns outwards under the abutment of the elastic element 52 until the second end of the joint 1 abuts against the inner wall of the workpiece 2. Specifically, as Figure 1 shown, the second end of the joint 1 after riveting has undergone an expansion deformation, so that the outer wall surface of the second end of the joint 1 is tightly riveted in the inner wall of the workpiece 2. Therefore, a tight riveted connection between the joint 1 and the workpiece 2 can be realized.

[0083] During the above riveting process, the joint 1 and the baffle 3 always need to keep their positions relative to the workpiece 2 unchanged. Therefore, the mandrel 4 can move stably relative to the joint 1 and the baffle 3.

[0084] As Figure 8 shown, it is a schematic diagram before the joint 1 is riveted. Among them, the position of the second end of the joint 1 for riveting is a cylindrical wall extending regularly in the axial direction. And as Figure 9 shown, it is a schematic diagram after the joint 1 is riveted. The position of the second end of the joint 1 is turned outwards and abuts against and is embedded in the inner wall of the workpiece 2, realizing the riveting and fixing.

[0085] Based on the above riveting process, the elastic element 52 can be pushed by the bulging element 6 to realize the eversion of the second end of the joint, so as to achieve riveting with a small bulge, which is easy to install and has high processing efficiency. Specifically, the mandrel 4 is used to drive the displacement of the bulging element 6, and the bulging element 6 abuts against the inner wall of the second end of the elastic element 52, causing the inner wall of the second end of the elastic element 52 to evert, and the second end of the workpiece 2 to evert, so as to realize riveting. After riveting, the size of the second end of the elastic element 52 protruding from the inner wall of the workpiece 2 is extremely small, and the resistance to liquid flow is small. Compared with the general riveting joint with a large bulge, it helps to improve the liquid cooling effect. And compared with the general mechanical connection methods such as welding, bonding, screwing, and interference fit, its riveting installation is simple, has high consistency, and good sealing performance. The deformed part of the second end of the riveted joint 1 on the inner wall side of the workpiece 2 has a very small proportion of the structure protruding along the vertical dimension, has a small resistance to liquid, and can significantly reduce the influence on the liquid flow in the workpiece 2.

[0086] The function of the baffle 3 is to prevent the displacement of the sleeve 51 when the mandrel 4 lifts the riveting mechanism 5. Therefore, under the clamping of the two ends of the sleeve 51 and the bulging element 6, the elastic element 52 with a certain elasticity can be caused to evert radially. That is to say, the baffle 3 is actually in a stationary state during the riveting process of this embodiment.

[0087] The mandrel 4 mainly plays a role in lifting the bulging element 6. The bulging element 6 is fixed at the second end of the mandrel 4, and the mandrel 4 can drive the bulging element 6 to move up and down. Before installation, the positions of the mandrel 4 and the bulging element 6 are closest to the second end position. In the fully riveted state, the positions of the mandrel 4 and the bulging element 6 are closest to the first end position. At this time, the elastic element 52 and the second end of the joint 1 have the largest degree of deformation.

[0088] In this embodiment, the material strength of the sleeve 51 in the riveting mechanism 5 is stronger than that of the elastic element 52. Therefore, under the pulling of the mandrel 4, the sleeve 51 will not deform, or only undergo a very small metal deformation, so that the elastic element 52 undergoes a large deformation.

[0089] The bulging element 6 can be set to a structure similar to a bullet head shape. The radial dimension of the second end of the bulging element 6 gradually decreases, forming an arc-shaped bullet head structure. Therefore, when the bulging element 6 is inserted into the joint 1, the second end of the bulging element 6 with the bullet head structure can play a guiding role, which helps to improve the success rate of insertion and avoid scratching.

[0090] The expansion element 6 and the core shaft 4 can be connected by welding, clamping or gluing, etc. In the present embodiment, the expansion element 6 is clamped and covered on the second end of the core shaft 4 in the shape of a shell, so that a stable connection is achieved between the expansion element 6 and the core shaft 4. The expansion element 6 has higher metal strength and is more wear-resistant, and uses less material, which helps to save costs.

[0091] Specifically, in the above-mentioned riveting process, the elastic element has a first state, which is a state before riveting. In the first state, the elastic element 52 is set to a tubular shape, and the outer diameter of the elastic element 52 is not greater than the inner diameter of the lumen. The elastic element 52 has a second state, which is a state after riveting. In the second state, the second end of the elastic element 52 is radially everted so that the outer wall of the second end of the joint 1 abuts against the inner wall of the workpiece 2. The process of changing from the first state to the second state is a riveting process, in which the elastic element 52 is a tubular shape with regular axial extension, and its second end gradually expands to have a trumpet-shaped opening, and the second end of the joint 1 is also a tubular shape with regular axial extension, and its second end gradually expands to have a trumpet-shaped opening, and is completely riveted and fitted on the inner wall of the workpiece 2.

[0092] In this embodiment, the first end of the elongated element 6 that contacts the inner wall of the elastic element 52 is provided with a guide slope 61. Specifically, the guide slope 61 is a slope with a gradually decreasing inner diameter from the second end to the first end. By providing the guide slope 61, when the elongated element 6 moves toward the first end, the guide slope 61 can scoop up the second end of the elastic element 52 more smoothly to avoid getting stuck. At the same time, when the inner wall of the elastic element 52 rubs against the guide slope 61, the friction force is smaller, avoiding scratches between each other and affecting the service life.

[0093] In this embodiment, the outer diameter of the expansion element 6 is not greater than the inner diameter of the lumen.
