Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a connector for full liquid cooling. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Currently, it is necessary to install joints on enclosed tubular workpieces to achieve liquid-cooled connections, thus requiring high standards for sealing and liquid flow. Existing technologies generally employ the following two methods for connection:

[0004] The first method is to use mechanical connection methods such as welding, bonding, screwing, and interference fit to connect the joint to the closed pipe workpiece. Some of these methods require the use of sealing media and sealing rings, resulting in low production efficiency, difficulty in quality control, high skill requirements for operators, and poor consistency in connection quality.

[0005] The second method uses the design and connection principle of rivet nuts to connect the joint to the enclosed tubular workpiece. However, after riveting, the joint protrusion left inside the enclosed tubing is large, which significantly reduces the heat exchange efficiency of the coolant and increases its liquid resistance. For liquid cooling systems in data centers and servers, heat exchange efficiency and coolant liquid resistance are critical indicators. Furthermore, the above-mentioned riveting method is difficult to apply to metal tubing with small cross-sectional dimensions.

[0006] Meanwhile, the existing joints are unstable in their connection to external pipelines and are inconvenient to install.

[0007] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0008] The purpose of this invention is to provide a fully liquid-cooled connector that can be riveted to the rivet hole of a workpiece via a deformable riveting part, and the mounting structure on the outer wall of the mounting part is easy to install and has good sealing performance.

[0013] The riveting part has a preset axial length so that after the riveting part deforms radially outward, it can be riveted to the inner wall surface of the riveting hole of the workpiece.

[0014] The connector has a cavity extending through the riveting portion, the flange portion, and the mounting portion. The fully liquid-cooled connector also has a cavity extending through the riveting portion, the flange portion, and the mounting portion.

[0015] As a further description of the above technical solution, the riveting part has a deformation seam that opens toward the end face of the riveting part.

[0016] As a further description of the above technical solution, the expansion joint extends axially and is provided to penetrate the riveting part axially.

[0024] This utility model also discloses a connecting assembly, wherein the connecting assembly consists of a connector and a workpiece as described above, the connector includes a connected riveting part, a flange part, and a mounting part, the workpiece has a riveting hole, and the riveting part is radially outwardly deformed and riveted to the inner wall surface of the workpiece at the riveting hole.

[0025] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0026] This utility model discloses a fully liquid-cooled connector that can be riveted to the rivet hole of a workpiece via a deformable riveting part. The mounting structure on the outer wall of the mounting part facilitates installation and provides excellent sealing. Specifically, the connector has a through-hole cavity. A riveting tool inserted into the cavity expands at its head, causing the riveting part to fold outwards. After radial outward deformation, the riveting part can be riveted to the inner wall of the rivet hole on the workpiece, thus achieving riveting fixation between the connector and the workpiece. The riveted part has minimal protrusion into the workpiece after riveting, resulting in low resistance to liquid flow. Compared to conventional riveted connectors with larger protrusions, this improves the liquid cooling effect. Furthermore, compared to conventional mechanical connection methods such as welding, bonding, screwing, and interference fits, its riveting installation is simple, consistent, and provides excellent sealing performance.

[0049] Please see Figure 1-2 This embodiment provides a fully liquid-cooled connector for riveting to workpiece 2. Workpiece 2 has riveting holes. The connector 1 includes:

[0050] The riveting part 13 is used to be installed in the riveting hole, and the inner wall of the riveting part 13 is set as a smooth wall surface.

[0051] Flange 11 is connected to riveting part 13. One end face of flange 11 facing riveting part 13 is used to abut against the outer wall of workpiece 2.

[0052] Mounting part 14 is connected to flange part 11 and is located on the side of flange part 11 away from riveting part 13. Mounting part 14 also includes connecting mechanism 141, which is used to connect to external pipeline.

[0053] The riveting part 13 has a preset axial length so that after the riveting part 13 deforms radially outward, it can be riveted to the inner wall surface of the riveting hole of the workpiece 2.

[0054] The connector 1 has a cavity through which the riveting part 13, the flange part 11, and the mounting part 14 are provided.

[0055] With the above structure, when riveting is required, firstly, the riveting part 13 of the connector 1 is inserted into the riveting hole of the workpiece 2, so that most of the riveting part 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 part 14 of the connector 1 is pressed and abutted against the outer wall surface of the workpiece 2. Then, as... Figure 3 As shown, an external riveting tool is inserted through the cavity of joint 1 from top to bottom. After it is in place, the end of the riveting tool is brought into contact with the riveting part 13 of joint 1, and the riveting tool is activated to expand radially outward. This causes the riveting part 13 to deform under the radial outward force, gradually turning outward. At this time, the riveting part 13 undergoes self-deformation. Figures 1 to 2 The state changes until the riveting part 13 is completely turned outward and riveted into the inner wall of the workpiece 2, so that the joint 1 and the workpiece 2 form a riveting fixed relationship. Then the riveting tool can be put away and taken out from the cavity from bottom to top, completing the entire riveting operation.

[0056] When it is necessary to connect external pipelines, a pipe head with a corresponding size is provided that matches the size of the connection mechanism 141 of the mounting part 14, and they are plugged into each other to form a tight connection between the pipeline and the mounting part 14. At this point, the sealed connection between the workpiece 2, the connector 1, and the external pipeline is completed. After the sealing test, coolant can be poured in.

[0057] Specifically, please see Figure 1 The connecting mechanism 141 is configured with an external thread on the outer wall of the mounting part 14, while the pipe head can have an internal thread that matches the connecting mechanism 141, and a tight threaded connection is formed between the internal thread and the external thread.

[0058] Please see Figure 3 The connecting mechanism 141 can also be configured to have an internal thread on the inner wall of the mounting part 14, and the pipe head can have an external thread that matches the connecting mechanism 141, forming a tight threaded connection between the internal thread and the external thread.

[0059] Please see Figure 4 The connecting mechanism 141 can also be configured as an annular structure that protrudes radially outward along the outer wall of the mounting part 14, and the pipe head can be a flexible hose with a certain elasticity. The flexible hose is sleeved on the outwardly protruding annular structure to form a tight elastic sealing connection.

[0060] Based on the structure of the above embodiment, the deformable riveting part 13 is riveted to the riveting hole of the workpiece 2, and the connecting mechanism 141 on the outer wall of the mounting part 14 is easy to install and has good sealing performance. Specifically, the joint 1 has a through-hole cavity. A riveting tool inserted into the cavity of the joint 1 can be used to expand the head position to drive the riveting part 13 to turn outward. After the riveting part 13 is deformed radially outward, it can be riveted to the inner wall surface of the riveting hole of the workpiece 2, thereby realizing the riveting fixation between the joint 1 and the workpiece 2. The riveting part 13 has a very small protrusion into the workpiece 2 after riveting, resulting in less resistance to liquid flow. Compared with riveting joints with larger protrusions, it helps to improve the liquid cooling effect. Compared with general mechanical connection methods such as welding, bonding, screwing, and interference fit, its riveting installation is simple, consistent, and has good sealing performance. The connecting mechanism 141 on the outer wall can achieve sealing fixation with the external pipeline by means of threaded connection or snap-fit, which has high connection efficiency and good sealing effect.

[0061] The inner wall of the riveting part 13 is set as a smooth wall surface, which can be used to cooperate with the riveting tool to perform riveting outward deformation. Compared with the traditional riveting structure, which requires setting internal threads to be fixed with the riveting tool and being riveted by the riveting mechanism, the riveting part 13 in this embodiment is easy to process and has a small protrusion size after outward riveting.

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

[0063] In this embodiment, the workpiece 2 of the closed-section metal pipe only needs to have the riveting part 13 of the corresponding joint 1 passed through the riveting hole during the riveting process, and then be turned up after riveting. Compared with the existing riveting method, its deformation does not require excessive upward pulling and abutting force on the workpiece 2 of the closed-section metal pipe. Therefore, the material strength requirement of the workpiece 2 in this embodiment is not high, the wall thickness can be thinner, and the thickness can be set between 0.5mm and 5.0mm, making it more widely applicable.

[0064] Before riveting, the joint 1 is generally a flange 11 with radial expansion in the middle and pipe structure with uniform vertical penetration at both ends. Considering that the internal bulge of the workpiece 2 should be small after riveting to reduce water resistance, the axial length of the riveting part 13 can be set to be only slightly longer than the actual thickness of the workpiece 2 before riveting. Specifically, the axial length of the riveting part 13 is about 2 to 5 times the actual thickness of the workpiece 2.

[0065] Therefore, please see Figure 2After the riveting part 13 deforms, the riveting part 13 is completely turned outward, and most of the outer wall of the riveting part 13 abuts against the inner wall of the workpiece 2 and is riveted. The length of the part of the riveting part 13 that is bent and abuts against the inner wall of the workpiece 2 is equivalent to the length of the riveting part 13 that contacts the inner 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 diameter of the riveting hole of the workpiece 2. Therefore, the riveting part 13 and the workpiece 2 can provide a high degree of sealing by means of the tight metal-to-metal fit.

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

[0068] Most importantly, through the riveting process of this embodiment, the riveting part 13 of the connector 1 is a single-layer thin metal wall that is turned outward and tightly attached to the workpiece 2. The riveting part 13 of the connector 1 protrudes very little from the inner wall of the workpiece 2. The side after riveting is almost flush with the inner wall of the workpiece 2, which reduces the water resistance inside the channel. In addition, the wall thickness of the workpiece 2 can be made thinner, resulting in better cost control of the overall product and making it easier to achieve miniaturization.

[0069] The following are some examples that can improve riveting performance or sealing performance:

[0070] Example 1

[0071] Please see Figure 1 , 2 The riveting portion 13 has a deformation slot 15 that opens towards the end face of the riveting portion 13. The deformation slot 15 extends axially and penetrates the riveting portion 13 axially. Multiple deformation slots 15 are provided, spaced at equal angles around the axial direction on the riveting portion 13. Preferably, in this embodiment, two deformation slots 15 spaced 180 degrees apart and penetrating the entire riveting portion 13 axially are provided. Specifically, the thickness of the deformation slot 15 is comparable to the wall thickness of the material of the riveting portion 13, so that the deformation process of the riveting portion 13 has less resistance and is smoother, and metal tearing and irregular deformation occur less frequently at the riveting portion 13. Specifically, the main purpose of providing the deformation slot 15 is to make the material of the riveting portion 13 more prone to deformation during the process of the riveting tool abutting from the inside out and turning outwards. Therefore, when the riveting portion 13 deforms outwards during the riveting process, such as... Figure 2As shown, deformation with outward expansion at the end also occurred at the expansion joint 15. The metal of the riveted parts 13 on both sides of the expansion joint 15 tended to separate from each other, thereby buffering the irregular deformation or even tearing of the riveted parts 13 during riveting deformation.

[0072] Example 2

[0073] like Figure 1 As shown, a sealing ring 12 is provided between the end face of the flange 11 facing the workpiece and the outer wall of the workpiece 2. The sealing ring 12 is positioned radially adjacent to the edge of the riveting hole. The sealing ring 12 effectively improves the sealing performance between the end face of the flange 11 facing the workpiece and the outer wall of the workpiece 2. When the sealing ring 12 is positioned against the edge of the riveting hole, it can also at least partially contact the outer wall of the riveting part 13. Therefore, the sealing ring 12 has the largest contact coverage surface with the external metal and can fill the gap, resulting in a better sealing effect.

[0074] Example 3

[0075] like Figure 1 As shown, a connecting portion 16 is also included between the flange portion 11 and the mounting portion 14, with a pipe cavity extending through the connecting portion 16. The function of the connecting portion 16 is to provide a conduit structure with an extended distance between the flange portion 11 and the connecting mechanism 141, ensuring that at least a long and stable liquid path exists between the workpiece 2 and the joint 1, or between the workpiece 2 and the joint 1, reducing liquid resistance and enabling continuous and stable liquid exchange between the joint 1 and the workpiece 2. Specifically, during the manufacturing stage, the connecting portion 16 is actually integrated with the mounting portion 14, with the connecting mechanism 141 being rolled out in an additional final step, reducing manufacturing costs. Under preferred conditions, the mounting portion 14 and the connecting portion 16, with the same axial length, maintain stable structural strength under the integrated construction of the mounting portion 14 and the connecting portion 16.

[0076] Please see Figure 6-9 This is a specific embodiment of riveting the joint of this utility model using a riveting tool.

[0077] The riveting tool includes a baffle 3;

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

[0079] 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 cavity. 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 connector 1.

[0080] The expansion element 6 is disposed at the second end of the mandrel 4;

[0081] The elastic element 52 is used so that when the expansion 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 expansion element 6, and after the abutment, the elastic element 52 flips outward so that the outer wall of the elastic element 52 flips the second end of the connector 1 outward.

[0082] With the above structure, in use, firstly, the second end of the connector 1 is inserted into the riveting hole of the workpiece 2, so that at least part of the second end of the connector 1 penetrates the inner wall of the workpiece 2; then, the liquid-cooled connector connecting riveting tool is inserted into the cavity of the connector 1, and the expanding element 6 protrudes from the second end of the cavity; the expanding element 6 extends out of the connector 1 and is located on one side of the inner wall of the workpiece 2; then, the mandrel 4 is pulled from the second end to the first end, so that the mandrel 4 drives the expanding element 6 to move, and the elastic element 52 of the riveting mechanism 5 is turned outward, so that the second end of the connector 1 is turned outward under the contact of the elastic element 52, until the second end of the connector 1 abuts against the inner wall of the workpiece 2. Specifically, as Figure 1 As shown, the second end of the riveted joint 1 undergoes expansion deformation, causing the outer wall of the second end of the joint 1 to be tightly riveted to the inner wall of the workpiece 2. Therefore, a tight riveted connection between the joint 1 and the workpiece 2 can be achieved.

[0083] During the riveting process described above, the joint 1 and the baffle 3 must always remain in a constant position relative to the workpiece 2, thus ensuring that the mandrel 4 can move stably relative to the joint 1 and the baffle 3.

[0084] like Figure 8 As shown, this is a schematic diagram of joint 1 before riveting. The second end of joint 1 is used for riveting at a location on the regularly axially extending cylinder wall. Figure 9 As shown, this is a schematic diagram of the riveted joint 1. The second end of the joint 1 is turned outward and then attached to and embedded in the inner wall of the workpiece 2, thus achieving the riveting fixation.

[0085] Based on the above riveting process, the expansion element 6 can push the elastic element 52 to achieve the outward turning of the second end of the joint, thereby achieving a riveting with a small protrusion, which is easy to install and has high processing efficiency. Specifically, the expansion element 6 is moved by the mandrel 4, causing the expansion element 6 to abut 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 turn outward, and causing the second end of the workpiece 2 to turn outward, thus achieving riveting. After riveting, the second end of the elastic element 52 protrudes very little from the inner wall of the workpiece 2, resulting in low resistance to liquid flow. Compared with riveted joints with larger protrusions, this helps to improve the liquid cooling effect. Compared with general mechanical connection methods such as welding, bonding, screwing, and interference fit, its riveting installation is simple, consistent, and has excellent sealing performance. The deformed part of the second end of the riveted joint 1 on one side of the inner wall of the workpiece 2 has a very small proportion of vertical protrusion, resulting in low resistance to liquid and significantly reducing the impact on the liquid flow in the workpiece 2.

[0086] The function of the baffle 3 is to prevent the sleeve 51 from displacing when the mandrel 4 pulls the riveting mechanism 5. Therefore, under the clamping of the sleeve 51 and the two ends of the expansion element 6, the elastic element 52 with a certain elasticity can be caused to turn outward in the radial direction. That is to say, the baffle 3 is actually in a stationary state during the riveting process in this embodiment.

[0087] The mandrel 4 primarily functions to lift the expansion element 6, which is fixed to the second end of the mandrel 4, allowing the mandrel 4 to move the expansion element 6 up and down. Before installation, the mandrel 4 and the expansion element 6 are closest to the second end. In the fully riveted state, the mandrel 4 and the expansion element 6 are closest to the first end, at which point the elastic element 52 and the second end of the connector 1 have the greatest 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 pull of the mandrel 4, the sleeve 51 will not deform or will only undergo a very small metal deformation, thus causing the elastic element 52 to undergo a large deformation.

[0089] The expansion element 6 can be configured as a bullet-shaped structure. The radial dimension of the second end of the expansion element 6 is gradually limited, forming an arc-shaped bullet structure. Therefore, when the expansion element 6 is inserted into the connector 1, the second end of the expansion element 6 of the bullet structure can play a guiding role, which helps to improve the success rate of insertion and avoid scratches.

[0090] The expansion element 6 and the mandrel 4 can be connected by welding, snap-fitting, or gluing. In this embodiment, the expansion element 6 is snap-fitted around the second end of the mandrel 4 in a shell-like manner, which makes the connection between the expansion element 6 and the mandrel 4 solid. Moreover, the expansion element 6, which has higher metal strength and is more wear-resistant, 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 the pre-riveting state. In the first state, the elastic element 52 is set as a tube, and the outer diameter of the elastic element 52 is not greater than the inner diameter of the tube cavity. The elastic element 52 has a second state, which is the post-riveting state. In the second state, the second end of the elastic element 52 is radially outward, 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 the riveting process, in which the elastic element 52, which is a tube extending in a regular axial direction, gradually expands its second end to have a flared opening, and the second end of the joint 1, which is also a tube extending in a regular axial direction, gradually expands its second end to have a flared opening and is completely riveted and fitted to the inner wall of the workpiece 2.

[0092] In this embodiment, a guide slope 61 is provided at the first end of the expanding element 6 that abuts against the inner wall of the elastic element 52. Specifically, the guide slope 61 is a ramp shape with an inner diameter that gradually decreases from the second end to the first end. By providing the guide slope 61, when the expanding element 6 moves towards the first end, the guide slope 61 can more smoothly lift the second end of the elastic element 52, avoiding jamming. At the same time, when the inner wall of the elastic element 52 rubs against the guide slope 61, the friction is reduced, avoiding mutual rubbing and affecting its lifespan.

[0093] In this embodiment, the outer diameter of the expanding element 6 is not greater than the inner diameter of the cavity. Preferably, the outer diameter of the expanding element 6 is equal to the inner diameter of the cavity. That is, without affecting the insertion of the expanding element 6 into the riveting hole of the workpiece 2, the larger the size of the expanding element 6, the more stable the thrust on the elastic element 52.

[0094] In this embodiment, the first end of the mandrel 4 includes an adapter 41 for connecting to the output end of a manual, pneumatic, hydraulic, or electric rivet gun. In this embodiment, the adapter 41 may be configured with a fixing hole recessed inward along the direction of the first end, facilitating the insertion and locking of an external transmission device.
