Description

Technical Field

[0001] This utility model relates to the field of server heat dissipation technology, specifically to a heat dissipation module. Background Technology

[0002] As servers become increasingly compact, chip sizes are shrinking. This reduction in chip size leads to an increase in heat flux density per unit area, thus increasing the risk of overheating. To minimize the risk of chip failure due to overheating, current technology employs air cooling. The heat sink absorbs the heat generated by the chip and transfers it to the air through convection.

[0003] Existing heat dissipation modules often adopt a fixed installation design, which is installed between the module and the base plate by bolts. This design cannot be flexibly adjusted according to different specifications and layouts of equipment. This rigid design limits the adaptability of the heat dissipation module to different equipment or different positions of the same equipment, increases the difficulty and cost of installation, and may also lead to poor heat dissipation effect due to improper installation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heat dissipation module. The module is rotatably mounted in the mounting hole via a mounting plate, which allows adjustment of the circumferential position of the floating bolt. The module is slidably mounted in the sliding hole via a sliding sleeve, which allows adjustment of the axial position of the floating bolt within the sliding hole. The two components work together to allow the floating bolt to be installed in any position, thus enabling flexible installation of the heat dissipation module and adapting it to different installation locations.

[0005] This utility model provides a heat dissipation module to solve the above-mentioned technical problems, including a base plate and a fixing plate. The fixing plate is provided with a heat-conducting plate, a fin assembly, and a heat pipe. The heat pipe is connected to the heat-conducting plate and inserted into the fin assembly. The fixing plate is provided with mounting structures at its four corners.

[0006] The mounting structure includes a coaxially arranged mounting hole and a fixing cylinder. A mounting plate is rotatably disposed in the mounting hole. A locking structure is provided between the mounting plate and the fixing cylinder. The mounting plate has a sliding hole. A sliding sleeve is slidably disposed in the sliding hole. A connecting hole is provided on the sliding sleeve. A floating bolt is movably fitted in the connecting hole. The stud of the floating bolt is threadedly connected to the base plate. An elastic element is sleeved on the floating bolt, with its two ends respectively abutting against the bolt head of the floating bolt and the sliding sleeve.

[0007] Furthermore, the locking structure includes a sleeve movably fitted on the fixed cylinder. The sleeve is connected to the mounting plate via a connector. Multiple sets of petals are arranged around the side of the sleeve near the fixed plate, with gaps between each petal. A locking sleeve with an inner cavity diameter that gradually decreases from the connector side to the fixed plate side is fitted over the petals. The locking sleeve is threadedly connected to the sleeve.

[0008] Furthermore, a limiting ring is provided at the upper end of the sleeve.

[0009] Furthermore, the locking sleeve is provided with anti-slip texture.

[0010] Furthermore, the central axis of the sliding hole coincides with the diameter of the mounting plate.

[0011] Furthermore, the heat pipe includes a flat portion and a pipe portion, the flat portion being pressed onto the heat-conducting plate, and the pipe portion being inserted into the fin assembly.

[0012] Furthermore, the fin assembly consists of multiple heat dissipation fins arranged with gaps, and the heat dissipation fins are provided with fixing holes and clearance grooves for the pipe section to be inserted.

[0013] The beneficial effects of this utility model are as follows: The base plate is used to install hardware components such as chips. The heat-conducting plate on the fixing plate is used to contact the heat source such as the chip and transfer the heat generated by the heat source. The heat pipe is connected to the heat-conducting plate and inserted into the fin assembly. The heat generated by the heat source is transferred to the heat pipe through the heat-conducting plate, and then to the fin assembly through the heat pipe. The heat is dissipated into the environment through air convection. The mounting structure at the four corners of the fixing plate is used to install the heat dissipation assembly, making it fit against the heat source. The mounting holes are used to rotate the mounting plate. The mounting plate has sliding holes, and a sliding sleeve is slidably installed in the sliding holes. The sliding sleeve is used to install the floating bolt. When the mounting plate rotates, the installation position of the floating bolt in the circumferential direction of the mounting plate can be adjusted. By sliding the sliding sleeve in the sliding hole, the axial position of the floating bolt in the sliding hole can be adjusted, thereby realizing the adjustment of the floating bolt at any position, which can adapt to different installation positions and realize the flexible installation of the heat dissipation module. The locking structure set between the mounting plate and the fixing cylinder can be used to prevent the mounting plate from rotating, ensuring the stability of the heat dissipation module after installation. The floating bolt is movably set in the connecting hole of the sliding sleeve, and through cooperation with the elastic element, it can adjust the pressure between the heat conduction plate and the heat source, provide the necessary pre-tightening force for the connection, and absorb external impacts and vibrations to ensure the stable operation of the heat dissipation module.

Detailed Implementation

[0020] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0021] Reference Figures 1 to 4 This utility model provides an embodiment of a heat dissipation module.

[0022] A heat dissipation module includes a base plate 1 and a fixing plate 2. The fixing plate 2 is provided with a heat-conducting plate 3, a fin assembly 4, and a heat pipe 5. The heat pipe 5 is connected to the heat-conducting plate 3 and inserted into the fin assembly 4. The base plate 1 is used to install hardware components such as chips. The heat-conducting plate 3 on the fixing plate 2 is used to contact heat sources such as chips and transfer the heat generated by the heat sources. The heat pipe 5 is connected to the heat-conducting plate 3 and inserted into the fin assembly 4. The heat generated by the heat sources is transferred to the heat pipe 5 through the heat-conducting plate 3 and then to the fin assembly 4 through the heat pipe 5. The heat is then dissipated into the environment through air convection.

[0023] Furthermore, the heat pipe 5 includes a flat portion 51 and a pipe portion 52. The flat portion 51 is pressed onto the heat-conducting plate 3, and the pipe portion 52 is inserted into the fin assembly 4. The flat portion 51 provides a larger contact area between the heat pipe 5 and the heat-conducting plate 3, thereby improving heat dissipation efficiency. The pipe is inserted into the fin assembly 4 to transfer heat to the fin assembly 4. Furthermore, the fin assembly 4 consists of multiple heat dissipation fins 41 arranged with gaps between them. The gaps between the heat dissipation fins 41 serve as air ducts. The heat dissipation fins 41 are provided with fixing holes 42 and clearance grooves 43 for the pipe portion 52 to be inserted. The pipe portion 52 of the heat pipe 5 bends upward and passes through the fixing hole 42 on the heat dissipation fin 41, and the upwardly bent portion of the heat pipe 5 is located in the clearance groove 43.

[0024] The fixing plate 2 has mounting structures 6 at its four corners to install the heat dissipation assembly, so that it fits against the heat source.

[0025] The mounting structure 6 includes a mounting hole 61 and a fixing cylinder 62 arranged coaxially. A mounting plate 63 is rotatably provided inside the mounting hole 61, and the mounting position of the floating bolt 66 in the circumferential direction of the mounting plate 63 can be adjusted.

[0026] A locking structure 64 is provided between the mounting plate 63 and the fixing cylinder 62. The locking structure 64 is used to prevent the mounting plate 63 from rotating, ensuring the stability of the heat dissipation module after installation. Further, the locking structure 64 includes a sleeve 641 movably fitted onto the fixing cylinder 62. The sleeve 641 is connected to the mounting plate 63 via a connector 642. Multiple sets of petals 643 are arranged around the side of the sleeve 641 closest to the fixing plate 2, with gaps between each petal 643. A locking sleeve 644 with an inner diameter that gradually decreases from the connector 642 side to the fixing plate 2 side is fitted over each petal 643. Further, the outer peripheral wall of the locking sleeve 644 has anti-slip textures to facilitate rotation of the locking sleeve 644. The locking sleeve 644 is threadedly connected to the sleeve 641. Further, a limiting ring 645 is provided at the upper end of the sleeve 641 to limit the upward movement distance of the locking sleeve 644 and prevent the locking sleeve 644 from disengaging from the sleeve 641. In this manner, when the rotating disk rotates to the required angle, the locking sleeve 644 is rotated to move the locking sleeve 644 upward, so that the small diameter section of the inner cavity of the locking sleeve 644 is pressed against each of the petals 643, and pressed against the fixing cylinder 62, thereby fixing the fixing cylinder 62 and the sleeve 641 relative to each other, thus achieving the fixation between the mounting disk 63 and the mounting hole 61.

[0027] The mounting plate 63 is provided with a sliding hole 631. Further, the central axis of the sliding hole 631 coincides with the diameter of the mounting plate 63. In this case, the sliding hole 631 has the longest length on the mounting plate 63, thereby increasing the installation range of the floating bolt 66. A sliding sleeve 65 is slidably disposed within the sliding hole 631. The sliding sleeve 65 is provided with a connecting hole 651, and the floating bolt 66 is movably fitted within the connecting hole 651, allowing adjustment of the floating bolt 66's axial position within the sliding hole 631. Furthermore, a limiting component can also be provided between the sliding sleeve 65 and the mounting plate 63 to achieve fixation between the sliding sleeve 65 and the mounting plate 63. Preferably, the sliding sleeve 65 is provided with a flange, on which a positioning bolt is provided. One side of the sliding hole 631 is provided with several positioning screw holes arranged along the axial direction of the sliding hole 631, which cooperate with the positioning bolt. The sliding sleeve 65 is fixed by screwing the positioning bolt into the positioning screw holes.

[0028] The stud of the floating bolt 66 is threadedly connected to the base plate 1. Furthermore, the base plate 1 is provided with a nut that mates with the floating bolt 66. The lower end of the floating bolt 66 passes through the sliding sleeve 65 and is threadedly connected to the nut to fix the heat dissipation module. An elastic element 67 is fitted on the floating bolt 66, with its two ends abutting against the bolt head of the floating bolt 66 and the sliding sleeve 65 respectively. This elastic element 67 can adjust the pressure between the heat conduction plate 3 and the heat source, provide the necessary preload for the connection, and absorb external impacts and vibrations to ensure the stable operation of the heat dissipation module.

[0029] In summary, by adopting this utility model, the mounting plate 63 is rotatably mounted in the mounting hole 61, which can adjust the position of the floating bolt 66 in the circumferential direction. The sliding sleeve 65 is slidably mounted in the sliding hole 631, which can adjust the position of the floating bolt 66 in the axial direction within the sliding hole 631. The two work together to achieve the installation of the floating bolt 66 in any position, realizing the flexible installation of the heat dissipation module and adapting to different installation positions.
