[0002] In existing personal computers or commercial servers, as the amount of computing continues to increase, traditional heat dissipation methods can no longer meet the needs of efficient heat dissipation. Therefore, more and more water cooling methods are used to dissipate heat from chips. This heat dissipation method uses circulating water to absorb and remove the heat generated by the chip, thereby ensuring that the chip can remain within the normal operating temperature range and ensure the stable operation of the system.

[0003] However, in actual applications, the joints in the water cooling device are often set in a fixed direction. This design limits the layout flexibility of the water cooling pipeline and increases the difficulty of laying out the water cooling pipeline. Especially in servers with multiple chips arranged in an array, since each chip needs to be connected to a water cooling plate for heat dissipation, the fixed-direction joints will make the connection between the water cooling pipelines complicated and difficult, which not only increases the difficulty of laying out, but may also affect the overall heat dissipation effect.

[0004] Based on the above, a water-cooled plate joint assembly and a cooling device are urgently needed to solve the above technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] The following is based on the attached Figure 1 To Attachment Figure 6 The utility model introduces a water cooling plate joint assembly and a cooling device.

[0040] like Figures 1 to 3As shown, the water-cooled plate joint assembly mainly includes a base plate 1, a pipe joint 2, a fixing part 3 and a sealing part 4. The base plate 1 serves as the basis of the entire water-cooled plate joint assembly and provides a stable installation platform. The pipe joint 2 is a key component for realizing the flow of water-cooling liquid, and its design enables the water-cooling liquid to flow smoothly into and out of the water-cooled plate joint assembly. The fixing part 3 is used to firmly fix the pipe joint 2 on the base plate 1 to ensure that it will not move or loosen during use. The sealing part 4 can be a sealing ring to play a sealing role, prevent the leakage of water-cooling liquid, and ensure the safety and stability of the entire water cooling system.

[0041] like Figures 4 to 6 As shown, in a specific implementation, the fixing member 3 is fixedly connected to the substrate 1, and a receiving cavity is formed between the fixing member 3 and the substrate 1. The receiving cavity is used to receive one end of the pipe connector 2, so that the pipe connector 2 can communicate with the flow channel hole 12 on the substrate 1. In order to achieve a better sealing effect, the substrate 1 has a first sealing surface, and the pipe connector 2 has a second sealing surface, and the two sealing surfaces are arranged oppositely. In the receiving cavity, a sealing ring is also arranged, and the sealing ring is sealed and clamped between the first sealing surface and the second sealing surface, thereby ensuring the sealing of the entire joint assembly.

[0042] Furthermore, the pipe joint 2 is rotatably inserted into the fixing member 3 in a direction perpendicular to the substrate 1, and the pipe joint 2 is rotatably arranged in the accommodating cavity in a direction perpendicular to the substrate 1. This design allows the pipe joint 2 to be flexibly adjusted according to actual needs, greatly improving the layout flexibility of the water cooling pipeline and reducing the difficulty of laying the water cooling pipeline. Especially in servers with multiple chips arranged in an array, this rotatable pipe joint 2 design can make the connection between water cooling pipelines simpler and more convenient, which not only reduces the difficulty of laying, but also helps to improve the overall heat dissipation effect.

[0043] In addition, the pipe connector 2 may include an integrated connector, and this design makes the structure of the pipe connector 2 more compact and stable, and helps to reduce the structural cost of the water cooling system. Exemplarily, in this embodiment, the pipe connector 2 includes a first part 21 and a second part 22 connected in an integral manner, and a water cooling channel is connected between the first part 21 and the second part 22. The axial directions of the first part 21 and the second part 22 are perpendicular to each other, the axial direction of the first part 21 is set in a direction parallel to the substrate 1, and the axial direction of the second part 22 is set in a direction perpendicular to the substrate 1. One end of the second part 22 passes through the fixing member 3 and is set in the accommodating cavity, and the other end of the second part 22 is located outside the accommodating cavity and is connected to the first part 21. The pipe connector 2 and the substrate 1 are preferably made of plastic, copper, steel, aluminum and the like, so as to facilitate the formation of a better flatness and roughness, and meet the friction and sealing requirements between the first sealing surface and the second sealing surface and the sealing ring.

[0044] like Figure 3As shown, the design of the fixing member 3 is also an important part of the entire water-cooled plate joint assembly. The fixing member 3 has a through hole 31 and a notch 32 connected to the through hole 31. The pipe joint 2 can pass through this notch 32, so that the pipe joint 2 can be passed through the hole 31 and arranged on the fixing member 3, which greatly facilitates the installation and disassembly of the pipe joint 2. In practical applications, the fixing member 3 can be designed as an annular member, the through hole 31 is arranged at the center position of the annular member, and the notch 32 is connected to the through hole 31 along the radial direction of the annular member. Optionally, the water-cooled plate joint assembly also includes bolts, which pass through the fixing member 3 and are threadedly connected to the substrate 1 to install the fixing member 3 on the substrate 1, and the pipe joint 2 is compressed by the fixing member 3, so that the sealing ring can effectively seal between the first sealing surface and the second sealing surface.

[0045] At the same time, in order to further improve the sealing effect, a mounting hole 11 may be provided on the substrate 1, the mounting hole 11 is connected with the flow channel hole 12 along the thickness direction of the substrate 1, and the diameter of the mounting hole 11 is larger than the flow channel hole 12, so that a stepped surface is formed between the mounting hole 11 and the flow channel hole 12. This stepped surface is the first sealing surface mentioned above, which cooperates with the second sealing surface of the pipe joint 2 to clamp the sealing ring and achieve a better sealing effect.

[0046] like Figure 6 As shown, a first annular protrusion 111 and a second annular protrusion 112 may be further provided on the stepped surface. The flow channel hole 12 is located in the first annular protrusion 111, and the first annular protrusion 111 is located in the second annular protrusion 112. A first mounting groove is formed between the first annular protrusion 111 and the second annular protrusion 112, and the first mounting groove can be used for limiting the installation of the sealing ring. This design not only facilitates the installation and replacement of the sealing ring, but also ensures the stability and sealing effect of the sealing ring.

[0047] In order to further enhance the sealing performance and stability, a third annular protrusion 113 may be provided on the stepped surface. The second annular protrusion 112 is located inside the third annular protrusion 113, so that a second mounting groove is formed between the second annular protrusion 112 and the third annular protrusion 113. A sealing ring may also be installed in this second mounting groove. In this way, the entire water-cooled plate joint assembly includes at least two sealing rings, which are respectively arranged in the first mounting groove and the second mounting groove. This double sealing design greatly improves the safety and stability of the entire water cooling system.

[0048] In addition, in order to limit the radial movement of the pipe joint 2 and enhance its stability, a limiting annular protrusion 221 can be provided on the second sealing surface. At the same time, a limiting groove is formed between the third annular protrusion 113 and the side wall of the mounting hole 11. The limiting annular protrusion 221 is inserted into the limiting groove. When the pipe joint 2 rotates, the limiting annular protrusion 221 is limited, avoiding the phenomenon of loosening and failure of the sealing ring, thereby ensuring the stability and reliability of the water-cooled plate joint assembly.

[0049] The utility model also provides a cooling device, which includes a flow channel plate 5 and the above-mentioned water-cooled plate joint assembly. The flow channel plate 5 is connected to the side of the base plate 1 of the water-cooled plate joint assembly away from the pipe joint 2, and forms a water-cooled flow channel. The flow channel hole 12 of the base plate 1 is connected to the water-cooled flow channel, thereby realizing the heat dissipation function of the entire cooling device. This cooling device is not only compact, stable and reliable, but also has a significant heat dissipation effect, and is very suitable for occasions such as personal computers or commercial servers that require efficient heat dissipation.

[0050] In the cooling device, the pipe joint 2 can be flexibly adjusted according to actual needs, which greatly improves the layout flexibility of the water cooling pipe and reduces the difficulty of laying out the water cooling pipe. Especially in a server with multiple chips arranged in an array, the design of the rotatable pipe joint 2 can make the connection between the water cooling pipes simpler and more convenient, which not only reduces the difficulty of laying out, but also helps to improve the overall heat dissipation effect.

[0051] It is understandable that the mounting hole 11 can reduce the total height of the entire water-cooled plate joint assembly to meet the installation requirements in a small space. For example, in this embodiment, along the thickness direction of the base plate 1, the total height from the flow channel plate 5 to the first portion 21 of the pipe joint 2 is no more than 22 mm.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
