Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a pipe fitting connector structure used between a liquid cooling module and a hose. The multi-segment design of the tubular body of the pipe fitting connector structure facilitates the insertion of the hose, reduces the insertion force of the hose, and improves the pull-out resistance and sealing performance of the hose after insertion. Background Technology

[0002] Currently, most water nozzles used in liquid cooling modules employ a single, long barbed fitting to ensure a tight seal during assembly. However, due to their considerable length, these fittings require significant installation space during assembly. In applications such as small cooling plates or high-density servers, they often need to penetrate the main body opening of the liquid cooling module for installation, leading to reduced structural strength at the module's edges and limiting its expandability. Furthermore, to ensure consistent hose crimping depth, jigs or measuring tools are typically used for positioning, complicating the assembly process and extending processing time. Moreover, the barbed fittings in traditional water nozzles are often smooth, resulting in insufficient friction and causing hose slippage or poor sealing, further impacting the overall system stability.

[0003] In view of this, it is necessary to provide a pipe fitting structure for use between liquid cooling modules and hoses. The multi-segment design of the tubular body of the pipe fitting structure facilitates the insertion of the hose, reduces the insertion force of the hose, and improves the pull-out resistance and sealing performance of the hose after insertion. This makes it suitable for applications such as liquid cooling plates, GPU liquid cooling modules, and high-density heat dissipation systems. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe fitting joint structure for use between a liquid cooling module and a flexible hose. Through the multi-segment design of the tubular body of the pipe fitting joint structure, the insertion force of the flexible hose is facilitated, while the pull-out resistance and sealing performance of the flexible hose after insertion are improved, preventing the flexible hose from slipping out, thereby improving the system stability. It is suitable for applications such as liquid cooling plates, GPU liquid cooling modules and high-density heat dissipation systems.

[0005] Another objective of this invention is to provide a pipe fitting structure. The pipe fitting structure includes a base and a tubular body. The base is disposed on the upper surface of the liquid cooling module to support the tubular body and connect to the internal flow channels of the liquid cooling module, ensuring stable fluid introduction or export. The tubular body has a multi-segment design, including a first section, a second section, and a third section. When a hose is inserted, it sequentially passes through the third section, the second section, and the first section of the tubular body and connects to the base, which assists in smooth hose insertion, reducing the insertion force during hose insertion, increasing the pull-out resistance after hose insertion, and improving sealing. The first section of the tubular body also includes a sealing section, which forms a sealed contact with the inner wall of the hose after insertion, preventing fluid leakage. The second section has at least one barb, the outer diameter of which increases along a first direction, allowing for segmental expansion of the hose, reducing the insertion force during hose insertion, increasing the pull-out resistance, and effectively reducing the risk of hose loosening. Roughening the surface of the at least one barb increases friction, further reducing the risk of hose slippage and liquid leakage. The third part of the tubular body also includes an inlet section and a neck section. The inlet section serves as an inlet to facilitate smooth insertion of the hose; the neck section limits the insertion depth to prevent excessive hose advancement. It is worth noting that the total length of a conventional water tap connector is typically 14 mm. However, to meet the needs of miniaturized systems, this invention shortens the length of the tubular body in the connector, reducing the total length to 11 mm. This effectively maintains the fixing strength and sealing performance while reducing the length, saving space, improving assembly efficiency and overall system stability. It is suitable for liquid cooling plates, GPU liquid cooling modules, and high-density heat dissipation systems.

[0006] To achieve the aforementioned objectives, this utility model provides a pipe fitting joint structure, which includes a base and a tubular body. The base is disposed on the upper surface of a liquid cooling module and has a side surface. The tubular body is connected to the liquid cooling module through the base, and the tubular body includes a first part, a second part, and a third part.

The second part is connected to the first part along the first direction, and the first part is disposed between the base and the second part along the first direction. The second part includes at least one barb, and the at least one barb is connected to the first part along the first direction. The first part is disposed between the at least one barb and the base along the first direction. The third part is connected to the second part along the first direction. The second part is disposed between the first part and the third part along the first direction, and the third part includes an inlet section and a neck section. The inlet section is connected to the neck section along the first direction, and the neck section is connected to the second part in the first direction, and the neck section is disposed between the second part and the inlet section along the first direction. The inlet section guides the insertion of a flexible tube in the first direction.

The at least one barb includes a first barb, a second barb, and a third barb, wherein the first barb, the second barb, and the third barb are arranged sequentially along the first direction and connected to the first part.

[0011] In one embodiment, the angle of the cone-shaped guide surface is between 10° and 20°.

[0012] In one embodiment, the conical guide surface of the first barb and the conical guide surface of the second barb are rough surfaces, while the conical guide surface of the third barb is a smooth surface.

[0015] In one embodiment, the outer diameter of the inlet section is smaller than the inner diameter of the inserted flexible tube.

[0017] In one embodiment, the base and the tubular body are formed as an integral structure.

Through the multi-segment design of the tubular body of the pipe fitting joint structure, it facilitates the insertion of the hose, reduces the insertion force, and simultaneously improves the pull-out resistance and sealing performance of the hose after insertion.

Figure 5B This is a schematic diagram showing the diameter of at least one barb portion of the pipe fitting joint structure according to the first embodiment of this utility model. (Reference) Figures 1 to 5B In this embodiment, the present invention provides a pipe fitting structure 2 for use between a liquid cooling module 1 and a flexible hose 6. The pipe fitting structure 2 includes a base 3 and a tubular body 4. The base 3 is disposed on the upper surface or top surface of the liquid cooling module 1 by means of welding or tight fitting, for example, and has a side surface 31. In this embodiment, the tubular body 4 is connected to the internal flow channel of the liquid cooling module 1 through the side surface 31 for the introduction or export of fluid (not shown).

[0032] It is worth noting that, in this embodiment, the overall length of the tubular body 4 is, for example, 11 mm, and it is designed with multiple segments, including at least a first segment 41, a second segment 42, and a third segment 43. The first segment 41 is connected to the side 31 of the base 3 along a first direction (i.e., the X-axis direction). The second segment 42 is connected to the first segment 41 along the first direction (i.e., the X-axis direction), and the first segment 41 is disposed between the base 3 and the second segment 42 along the first direction (i.e., the X-axis direction). Furthermore, in this embodiment, the second segment 42 includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423, connected to the first segment 41 along the first direction (i.e., the X-axis direction). The first segment 41 is disposed between the first barb 421, the second barb 422, or the third barb 423 and the base 3 along the first direction (i.e., the X-axis direction). In this embodiment, the third part 43 is connected to the second part 42 along the first direction (i.e., the X-axis direction), and the second part 42 is disposed between the first part 41 and the third part 43 along the first direction (i.e., the X-axis direction). In this embodiment, the third part 43 includes an inlet section 431 and a neck section 432. The inlet section 431 is connected to the neck section 432 along the first direction (i.e., the X-axis direction), and the neck section 432 is connected to the second part 42 along the first direction (i.e., the X-axis direction), and is disposed between the second part 42 and the inlet section 431 along the first direction (i.e., the X-axis direction). In this embodiment, the inlet section 431 guides the insertion of the flexible hose 6 along the first direction (i.e., the X-axis direction). By providing the first barb 421, the second barb 422, or the third barb 423, the pull-out resistance of the flexible hose 6 is increased, effectively reducing the risk of loosening and preventing liquid leakage. Of course, this invention is not limited to this.

[0033] In this embodiment, the tubular body 4 has a multi-segment design, including at least a first segment 41, a second segment 42, and a third segment 43. When the flexible hose 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along a first direction (i.e., the X-axis direction) and connects to the base 3. In addition, in this embodiment, the second segment 42 also includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423. In this embodiment, the first barb 421, the second barb 422, and the third barb 423 of the second segment 42 increase the outer tube diameter along the first direction (i.e., the X-axis direction), and conical guide surfaces 5a, 5b, and 5c are formed on the outer periphery of the first barb 421, the second barb 422, and the third barb 423. The conical guide surfaces 5a, 5b, and 5c gradually expand the inserted hose 6 along the first direction (i.e., the X-axis direction). By setting conical guide surfaces 5a, 5b, and 5c from small to large, the hose 6 is gradually expanded to reduce the insertion force when the hose 6 is inserted.

[0034] In this embodiment, the tubular body 4 has a multi-segment design, including at least a first segment 41, a second segment 42, and a third segment 43. When the flexible tube 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along a first direction (i.e., the X-axis direction) and connects to the base 3. The second segment 42 further includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423. Furthermore, in this embodiment, the first barb 421, the second barb 422, or the third barb 423 of the second segment 42 is disposed between the first segment 41 and the third segment 43 along the first direction (i.e., the X-axis direction). In this embodiment, the first barb 421, the second barb 422, and the third barb 423 are arranged sequentially along the first direction (i.e., the X-axis direction) and connected to the first segment 41. In this embodiment, the diameter C of the first barb 421 is smaller than the diameter D of the second barb 422, the diameter D of the second barb 422 is smaller than the diameter E of the third barb 423, and the first barb 421, the second barb 422, and the third barb 423 respectively also include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c. The conical guide surfaces 5a, 5b, and 5c each form a cone angle relative to the first direction (i.e., the X-axis direction), and the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c are angle Q, angle R, and angle S, respectively.

[0035] In this embodiment, the tubular body 4 has a multi-segment design, including a first segment 41, a second segment 42, and a third segment 43. When the flexible hose 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along a first direction (i.e., the X-axis direction) and connects to the base 3. In addition, in this embodiment, the second segment 42 also includes a first barb 421, a second barb 422, and a third barb 423. In this embodiment, the diameter C of the first barb 421 is smaller than the diameter D of the second barb 422, and the diameter D of the second barb 422 is smaller than the diameter E of the third barb 423. The first barb 421, the second barb 422, and the third barb 423 each include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c. The conical guide surfaces 5a, 5b, and 5c each form a cone angle relative to the first direction (i.e., the X-axis direction), and the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c are angles Q, R, and S, respectively. In this embodiment, the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c, angles Q, R, and S, are between 10° and 20° to balance the insertion force and pull-out force of the flexible hose 6. It should be emphasized that the tubular body 4 is designed with multiple segments. The overall length of the first segment 41, the second segment 42, and the third segment 43 connected in sequence is, for example, 11 mm, which is less than the 14 mm of a typical conventional faucet connector. In this embodiment, the angles of the first barb 421, the second barb 422, and the third barb 423 of the second segment 42, through the conical guide surfaces 5a, 5b, and 5c, are limited to between 10° and 20°, which is more conducive to shortening the overall length of the second segment 42 or the tubular body 4. Of course, this utility model is not limited to this.

[0036] In this embodiment, the tubular body 4 has a multi-segment design, including a first segment 41, a second segment 42, and a third segment 43. When the flexible tube 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along a first direction (i.e., the X-axis direction) and connects to the base 3. In addition, in this embodiment, the second segment 42 further includes a first barb 421, a second barb 422, and a third barb 423. In this embodiment, the diameter C of the first barb 421 is smaller than the diameter D of the second barb 422, the diameter D of the second barb 422 is smaller than the diameter E of the third barb 423, and the first barb 421, the second barb 422, and the third barb 423 respectively also include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c. In this embodiment, the conical guide surface 5a of the first barb 421 and the conical guide surface 5b of the second barb 422 are rough surfaces, which are used to increase the contact friction force in the initial stage of insertion of the hose 6 to prevent the hose from slipping. The conical guide surface 5c of the third barb 423 is a smooth surface, which can reduce resistance and ensure smooth insertion and sealing stability in the final positioning section of the hose 6 insertion.

[0037] In this embodiment, the conical guide surface 5a of the first barb 421 and the conical guide surface 5b of the second barb 422 are rough surfaces. Furthermore, in this embodiment, the rough surface includes a plurality of knurled grooves 51. Each of the plurality of knurled grooves 51 has a pitch A, which ranges from 0.2 mm to 0.6 mm. Each of the plurality of knurled grooves 51 has a depth B, which ranges from 0.06 mm to 0.1 mm. By providing a plurality of knurled grooves 51, the contact friction is increased, further improving the anti-slip effect and preventing the hose 6 from slipping. Of course, this invention is not limited to this.

[0038] In this embodiment, the tubular body 4 has a multi-segment design, including a first segment 41, a second segment 42, and a third segment 43. When the flexible hose 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along the first direction (i.e., the X-axis direction) and connects to the base 3. In addition, in this embodiment, the first segment 41 also includes a sealing segment 411, which is disposed along the first direction (i.e., the X-axis direction) between the base 3 and the third barb 423 of the second segment 42, and is tightly fitted with the flexible hose 6 to prevent the flexible hose 6 from slipping and improve the sealing performance.

[0039] In this embodiment, the tubular body 4 has a multi-segment design, including a first segment 41, a second segment 42, and a third segment 43. When the flexible tube 6 is inserted, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along the first direction (i.e., the X-axis direction) and connects to the base 3. In addition, in this embodiment, the third segment 43 also includes an inlet segment 431 and a neck segment 432. The outer diameter of the inlet segment 431 of the third segment 43 is smaller than the inner diameter of the inserted flexible tube 6 to facilitate the insertion of the flexible tube 6 and reduce damage to the flexible tube 6.

[0040] In this embodiment, the tubular body 4 has a multi-segment design, including a first segment 41, a second segment 42, and a third segment 43. When the hose 6 is connected, it sequentially passes through the third segment 43, the second segment 42, and the first segment 41 of the tubular body 4 along the first direction (i.e., the X-axis direction) and connects to the base 3. Additionally, in this embodiment, the pipe fitting structure 2 also includes a pipe clamp 7, which secures the hose 6 and the tubular body 4. The pipe clamp 7 is located in the first and second segments to improve sealing and prevent liquid leakage. It should be noted that the pipe clamp 7 is located in at least one of the first segment 41, the second segment 42, and the third segment 43. It is worth noting that the crimping section of the pipe clamp used in conventional faucet fittings is typically 3 mm. However, to further improve assembly efficiency and reduce volume, the pipe clamp 7 of this invention adopts a 2 mm crimping section design. This shortens the crimping length while effectively maintaining the fixing strength and sealing performance, and reduces material usage, thus reducing space requirements and manufacturing costs.

[0041] In this embodiment, the base 3 is disposed on the upper surface of the liquid cooling module 1 along a second direction perpendicular to the liquid cooling module 1 (i.e., the Y-axis direction). The tubular body 4 is connected to the base 3 through the side of the base 3 and communicates with the internal flow channel of the liquid cooling module 1. The base 3 and the tubular body 4 are formed as an integral structure, forming an L-shaped structure. This integral structure can effectively simplify the manufacturing process and reduce manufacturing costs. It should be noted that the side of the liquid cooling module 1 used in this invention is usually provided with components that interface with other cooling or electronic components, so the side space is limited and it is not possible to configure additional pipes or connectors. Therefore, the pipe connector structure 2 provided by this invention is perpendicular to the upper surface of the liquid cooling module 1, which can complete the flow connection in a limited installation space to improve the scalability of the module.

[0042] Figure 6 This is a three-dimensional structural diagram showing the application of the pipe fitting joint structure of the second embodiment of this utility model between the liquid cooling module and the hose. Figure 7 This is a side view of the pipe fitting joint structure of the second embodiment of the present invention applied between the liquid cooling module and the hose. Figure 8 This is a perspective structural diagram of the pipe fitting joint structure according to the second embodiment of this utility model. (Reference) Figures 6 to 8 In this embodiment, the pipe fitting joint structure 2a is generally similar to... Figures 1 to 4The pipe fitting structure 2 shown uses the same component designation to represent the same components, structures, and functions, and will not be described again here. In this embodiment, the base 3a of the pipe fitting structure 2a is disposed on the upper surface of the liquid cooling module 1a along a second direction Y perpendicular to the liquid cooling module 1a. The tubular body 4a of the pipe fitting structure 2a is connected to the base 3a through the side 31a of the base 3a. The tubular body 4b is connected to the base 3a through the opposite side 31b of the side 31a, forming an integral T-shaped structure. This configuration enables the arrangement of multiple liquid passages within a limited space, achieving the benefits of space saving and increased device expandability.

[0043] In the aforementioned embodiments, to facilitate the connection of the flexible hose 6 to the tubular bodies 4 and 4a of the fitting connector structures 2 and 2a, the second part 42 of the tubular bodies 4 and 4a further includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423. In this embodiment, the diameter C of the first barb 421 is smaller than the diameter D of the second barb 422, the diameter D of the second barb 422 is smaller than the diameter E of the third barb 423, and the first barb 421, the second barb 422, and the third barb 423 respectively include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c, wherein the conical guide surfaces 5a, 5b, and 5c respectively form a cone angle relative to the first direction (i.e., the X-axis direction), and the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c are angle Q, angle R, and angle S, respectively. It is worth noting that, in this embodiment, the angle Q of the cone angle of the cone-shaped guide surface 5a of the first barb 421 is smaller than the angle R of the cone angle of the cone-shaped guide surface 5b of the second barb 422, and the angle R of the cone angle of the cone-shaped guide surface 5b of the second barb 422 is smaller than the angle S of the cone angle of the cone-shaped guide surface 5c of the third barb 423. By gradually increasing the angle of the cone angle of each barb, the hose can be gradually expanded during insertion, thereby reducing the insertion force during hose insertion to avoid hose damage and improving the hose's resistance to pull-out after insertion to increase sealing performance.

[0044] In the aforementioned embodiments, to facilitate the connection of the flexible hose 6 to the tubular bodies 4 and 4a of the fitting joint structures 2 and 2a, the second part 42 of the tubular bodies 4 and 4a further includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423. The diameter C of the first barb 421 is smaller than the diameter D of the second barb 422, and the diameter D of the second barb 422 is smaller than the diameter E of the third barb 423. The first barb 421, the second barb 422, and the third barb 423 each include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c. The conical guide surfaces 5a, 5b, and 5c each form a cone angle relative to the first direction (X-axis direction), and the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c are angle Q, angle R, and angle S, respectively. It is worth noting that, in this embodiment, the cone angles Q, R, and S of the conical guide surface 5a of the first barb 421, the conical guide surface 5b of the second barb 422, and the conical guide surface 5c of the third barb 423 are the same. This ensures that the hose is guided segment by segment along the same angular direction during insertion, thereby maintaining smooth insertion and sealing, and improving the stability of hose 6 insertion and removal. By using consistent barb angles, the manufacturing process can be simplified, achieving a stable structure and simple manufacturing.

[0045] In the aforementioned embodiments, to facilitate the connection of the flexible hose 6 to the tubular bodies 4 and 4a of the fitting connector structures 2 and 2a, the second part 42 of the tubular bodies 4 and 4a further includes at least one barb, such as a first barb 421, a second barb 422, or a third barb 423. The first barb 421, the second barb 422, and the third barb 423 respectively include a conical guide surface 5a, a conical guide surface 5b, and a conical guide surface 5c. The conical guide surfaces 5a, 5b, and 5c each form a cone angle relative to the first direction (i.e., the X-axis direction), and the angles of the cone angles of the conical guide surfaces 5a, 5b, and 5c are angle Q, angle R, and angle S, respectively. It is worth noting that, in this embodiment, the diameters C of the first barb 421, D of the second barb 422, and E of the third barb 423 are the same length, and the angle Q of the conical guide surface 5a of the first barb 421 is smaller than the angle R of the conical guide surface 5b of the second barb 422, and the angle R of the conical guide surface 5b of the second barb 422 is smaller than the angle S of the conical guide surface 5c of the third barb 423. By gradually increasing the angle of the cone of each barb, the hose can expand segment by segment during insertion, thereby reducing the insertion force and preventing damage to the hose due to excessive force. Simultaneously, by ensuring that the diameters of each barb are the same, the hose can fit evenly against each barb after insertion, thereby improving pull-out resistance and enhancing overall sealing performance.

[0046] It should be noted that the above embodiments are merely examples for the purpose of illustration, and the scope of the rights claimed by this utility model should be determined by the claims, and not limited to the above embodiments.

[0047] In summary, this utility model provides a pipe fitting connector structure. This pipe fitting connector structure is used to connect a liquid cooling module and a hose. Through the multi-segment design of the tubular body in the pipe fitting connector structure, it facilitates hose insertion, reduces the insertion force, and simultaneously improves the pull-out resistance and sealing performance of the hose after insertion. The pipe fitting connector structure includes a base and a tubular body. The base is disposed on the upper surface of the liquid cooling module to support the tubular body and connects to the internal flow channels of the liquid cooling module, ensuring stable fluid introduction or export. The tubular body has a multi-segment design, including a first section, a second section, and a third section. When the hose is inserted, it passes through the third section, the second section, and the first section of the tubular body sequentially and connects to the base, which assists in smooth hose insertion, achieving the effects of reducing the insertion force, improving the pull-out resistance, and enhancing sealing performance. The first section of the tubular body includes a sealing section, which forms a sealing contact with the inner wall of the hose after insertion, preventing fluid leakage. The second part has at least one barb, the outer diameter of which increases along the first direction, allowing for gradual expansion of the hose, reducing insertion force and increasing pull-out resistance, effectively reducing the risk of hose loosening. Furthermore, the outer periphery of the at least one barb forms a conical guide surface, which gradually expands the hose's inner diameter along the first direction, and further forms knurled grooves on the surface to increase the coefficient of friction, thereby improving anti-slip effect and sealing performance. The third part also includes an inlet section and a neck section. The inlet section serves as an inlet to assist in smooth hose insertion. The neck section limits the hose insertion depth to prevent excessive hose advancement. In one embodiment, the base and tubular body are integrally formed into an L-shaped structure, suitable for liquid cooling modules, solving applications with limited side space, allowing coolant to flow vertically into and out of the module's internal channels. In another embodiment, the pipe joint can form a T-shaped structure, allowing liquid to flow between different channels, achieving space saving and increasing module expandability. Through the above structural combination, the pipe fitting of this utility model can shorten the overall structural length while balancing insertion force and pull-out force, and providing excellent sealing performance, effectively reducing the risk of hose loosening and liquid leakage. Furthermore, through the configuration of multiple barbed sections and the roughening of the barbed surface, the hose can obtain stable guidance and anti-slip effect during insertion and positioning, and the crimping depth can be ensured without the need for additional jigs or measuring tools, simplifying the assembly process and shortening the processing time. Overall, the pipe fitting structure of this utility model has the advantages of high sealing performance and high reliability. Compared with the total length of a conventional water tap fitting of approximately 14 mm, this utility model, to meet the needs of miniaturized systems, shortens the length of the tubular body, designing the total length of the pipe fitting to 11 mm. This shortens the length while effectively maintaining the fixing strength and sealing performance, achieving the effects of saving space, improving assembly efficiency, and improving the overall system stability. It is suitable for applications such as liquid cooling plates, GPU liquid cooling modules, and high-density heat dissipation systems.
