Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically a radiator with a biomimetic fin structure. Background Technology

[0002] In industrial production and the operation of numerous electronic devices, heat dissipation is a crucial factor in ensuring stable and efficient operation. Finned tube heat sinks, with their excellent heat dissipation performance, have been widely used in various fields. Traditional finned tube heat sinks have relatively conventional fin structures. However, with technological advancements and ever-increasing demands for heat dissipation efficiency, existing finned tubes have revealed many problems that urgently need to be addressed.

[0003] In actual operating conditions, finned tubes are exposed to harsh environments such as high temperature, high humidity, and strong corrosion for extended periods, making them prone to wear, corrosion, and performance degradation. Once a finned tube fails, it must be replaced to ensure the radiator maintains good heat dissipation. However, existing finned tubes are mostly connected to other radiator components via welding during installation. While welding ensures structural stability, the removal process is extremely difficult when replacing finned tubes. Specialized tools are required to cut and grind the weld points, which not only consumes significant manpower and resources but also risks damaging surrounding pipes and equipment, leading to further maintenance costs and time losses. Utility Model Content

[0004] The purpose of this invention is to provide a heat sink with a biomimetic fin structure to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A heat sink with a biomimetic fin structure includes an outer frame. Each pair of opposing inner walls of the outer frame has openings, and heat dissipation pipes are connected between the opposing openings. Spiral fins are mounted on the outer sides of each heat dissipation pipe. A pair of fixing blocks are mounted on the outer sides of each heat dissipation pipe near both ends. A sliding hole is provided on one side of each fixing block, and a threaded rod is engaged within the sliding hole. A connecting hole is provided on the other side of each fixing block, and a fixing rod slides within the connecting hole. The threaded rod presses against the fixing rod. A pair of fixing holes are provided on the inner walls of the outer frame near the openings, and the fixing rod and... The fixing holes engage, and an arc-shaped tube connects adjacent openings. An inlet pipe and an outlet pipe are located on the outer side of the outer frame. The inlet pipe communicates with one of the outermost openings, and the outlet pipe communicates with the other outermost opening. The spiral fins mimic the spiral structure of a conch shell or plant vines, thus increasing the heat dissipation area of ​​the heat pipe and improving heat dissipation efficiency. The combination of fixing blocks, threaded rods, fixing rods, and fixing holes makes the installation and disassembly of the heat pipe more convenient than traditional welding methods, reducing maintenance costs and time, and preventing easy damage to surrounding equipment.

[0007] Furthermore, a limiting groove is formed inside the fixing block, and a limiting block is installed on the outside of the fixing rod. The limiting block slides in the limiting groove, and a spring is connected between the limiting block and the limiting groove. The cooperation of the limiting groove, the limiting block and the spring can prevent the fixing rod from completely falling out of the connecting hole. At the same time, when the threaded rod is removed, the spring can make the fixing rod disengage from the fixing hole, so that the user can remove the heat sink.

[0008] Furthermore, a storage opening is provided on the inner wall of the sliding hole, and a pressure plate is installed at one end of the fixing rod located in the sliding hole. The side of the pressure plate that contacts the threaded rod is a concave arc surface. The pressure plate can slide into the storage opening. The concave arc surface can increase the contact area between the pressure plate and the threaded rod. At the same time, after being squeezed, it can move into the storage opening to ensure that it will not affect the threaded rod.

[0009] Furthermore, the connecting hole penetrates the limiting groove and communicates with the storage port.

[0010] Furthermore, the sliding hole is provided with threads near its opening. The threads at the opening of the sliding hole facilitate the installation and positioning of the threaded rod, making the threaded rod more stable during rotation and less prone to shaking, thus improving the reliability of fixing the heat dissipation pipe. At the same time, the position of the threads is limited, which can prevent the threads from interfering with the pressure plate.

[0011] Furthermore, the fixing block on the outermost heat dissipation pipe faces outward, which facilitates the installation, disassembly, and maintenance of the outermost heat dissipation pipe. The fixing block can be operated directly without disassembling other parts, thus improving maintenance efficiency.

[0012] Furthermore, sealing rings are installed at both ends of the heat dissipation pipe. The sealing rings can effectively prevent the hot fluid from leaking at the connection between the heat dissipation pipe and the opening, ensure the normal flow of the hot fluid in the heat dissipation pipe, and improve the sealing and stability of the heat dissipation system.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This radiator with a biomimetic fin structure uses a combination of a fixing block, a threaded rod, a fixing rod, and a fixing hole to replace the traditional welding connection method, making the installation and disassembly of the heat sink tubes simple and convenient. During installation, simply align the fixing rod with the fixing hole, rotate the threaded rod to press the fixing rod into the fixing hole, and the installation is complete. During disassembly, simply rotate the threaded rod in the opposite direction to disengage the fixing rod from the fixing hole, and the heat sink tube can be easily removed. This design avoids the complex operations of cutting and grinding weld points required when replacing finned tubes using welding methods, saving manpower and material costs, while also shortening maintenance time and improving maintenance efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 8 This utility model provides a technical solution: a heat sink with a biomimetic fin structure, including an outer frame 1. A pair of opposite inner walls of the outer frame 1 are provided with openings 9, and heat dissipation pipes 5 are connected between the opposite openings 9. Spiral fins 6 are installed on the outer sides of the heat dissipation pipes 5. A pair of fixing blocks 7 are installed near both ends of the outer sides of the heat dissipation pipes 5. A sliding hole 11 is provided on one side of the fixing block 7, and a threaded rod 12 is engaged within the sliding hole 11. A connecting hole 18 is provided on the other side of the fixing block 7, and a fixing rod 19 slides within the connecting hole 18. The threaded rod 12 presses against the fixing rod 19. A pair of fixing holes 10 are provided on the inner walls of the outer frame 1 near the openings 9, and the fixing rod 19 engages with the fixing holes 10. An arc-shaped tube 2 is connected between adjacent openings 9. The outer side of the outer frame 1 is provided with... The water inlet pipe 3 and the water outlet pipe 4 are connected. The water inlet pipe 3 is connected to one of the outermost openings 9, and the water outlet pipe 4 is connected to the other outermost opening 9. The hot fluid flows in from the water inlet pipe 3, enters the heat dissipation pipe 5 through the opening 9, and flows into the next heat dissipation pipe 5 through the arc-shaped pipe 2, and flows out through the water outlet pipe 4. When flowing in the heat dissipation pipe 5, the heat is transferred to the spiral fins 6 through the pipe wall of the heat dissipation pipe 5, and then dissipated into the surrounding environment. When installing the heat dissipation pipe 5, the fixing rod 19 is aligned with the fixing hole 10 on the inner wall of the outer frame 1. The threaded rod 12 is rotated to move it in the sliding hole 11 and squeeze the fixing rod 19, so that the fixing rod 19 is inserted into the fixing hole 10, thereby fixing the heat dissipation pipe 5. When disassembling, the threaded rod 12 is rotated in the opposite direction to make the fixing rod 19 disengage from the fixing hole 10, and the heat dissipation pipe 5 can be removed.

[0025] As an embodiment of this utility model, a limiting groove 14 is further formed inside the fixing block 7, and a limiting block 15 is installed on the outside of the fixing rod 19. The limiting block 15 slides within the limiting groove 14, and a spring 16 is connected between the limiting block 15 and the limiting groove 14. During the installation and removal of the heat dissipation pipe 5, the limiting block 15 slides within the limiting groove 14, limiting the movement range of the fixing rod 19. When the threaded rod 12 presses against the fixing rod 19, the spring 16 is compressed; when the threaded rod 12 is removed, the spring 16 returns to its original deformation, causing the fixing rod 19 to disengage from the fixing hole 10.

[0026] As an embodiment of the present invention, the inner wall of the sliding hole 11 is provided with a storage port 17, and a pressure plate 13 is installed at one end of the fixing rod 19 located in the sliding hole 11. The side of the pressure plate 13 that contacts the threaded rod 12 is a concave arc surface, and the pressure plate 13 can slide into the storage port 17.

[0027] As one embodiment of the present invention, the connecting hole 18 penetrates the limiting groove 14 and communicates with the storage port 17.

[0028] As an embodiment of this utility model, the sliding hole 11 is further provided with a thread near its opening. When installing the threaded rod 12, its threaded portion is aligned with the thread at the opening of the sliding hole 11 and screwed in. Through the engagement of the threads, the threaded rod 12 can be more securely installed in the sliding hole 11.

[0029] As an embodiment of this utility model, the fixing block 7 on the outermost heat dissipation pipe 5 faces outward. When repairing or replacing the outermost heat dissipation pipe 5, since the fixing block 7 faces outward, the operator can directly contact the threaded rod 12 on the fixing block 7 and perform rotation operation to fix or remove the heat dissipation pipe 5. There is no need to perform complicated disassembly work due to space limitations or other components blocking the way, which simplifies the maintenance process.

[0030] As an embodiment of this utility model, sealing rings are further installed at both ends of the heat dissipation pipe 5. When the hot fluid flows in the heat dissipation pipe 5, the sealing rings fill the gap between the heat dissipation pipe 5 and the opening 9, and prevent the hot fluid from leaking out from the connection by using their own elastic deformation.
