Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to a large-caliber flow-increasing radiator sheet. Background Art

[0002] The purpose of the increased flow heat sink is to increase the heat dissipation capacity and efficiency of the radiator. Large-diameter increased flow heat sinks usually adopt a wider and flatter shape to increase the surface area of ​​the radiator and provide more heat dissipation surface. Large-diameter increased flow heat sinks also use materials with higher thermal conductivity, such as aluminum alloy or copper, to improve the heat conduction efficiency of the radiator and transfer heat to the surrounding environment faster, thereby increasing the heat exchange area between the radiator and the surrounding air to ensure the normal operation and long-term stable operation of the equipment.

[0003] For example, the application number CN219551268U discloses an annular fin heat sink, including a mounting frame, a pipe assembly is installed on the inner side of the mounting frame, a heat dissipation assembly is installed on the inner side of the mounting frame, the pipe assembly includes a water outlet pipe fixedly connected to the left side of the mounting frame, a serpentine pipe is fixedly installed on the right end of the water outlet pipe, four support blocks are fixedly connected between the outer side of the serpentine pipe and the inner side of the mounting frame, a booster pump is fixedly connected to the right end of the serpentine pipe, a water inlet pipe is fixedly connected to the right side of the booster pump, four support feet are fixedly connected to the bottom of the mounting frame and are evenly distributed, the heat dissipation assembly includes ten heat conducting plates slidably connected to the outer side of the serpentine pipe, and twenty annular sheets arranged at equal distances are fixedly connected to the outer side of the heat conducting plates. The annular fin heat sink can conveniently and effectively clean the fins, thereby effectively improving the practicality of the fin heat sink.

[0004] However, the large-diameter flow-increasing radiator fins are often directly welded to the heat pipes. When the heat dissipation efficiency cannot be improved due to accidental damage during use, the heat dissipation fins cannot be replaced individually and the heat pipes must be replaced as a whole, which increases the waste of resources and the difficulty of maintenance and replacement.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a large-diameter flow-increasing heat sink is proposed. Utility Model Content

[0006] The utility model aims to provide a large-diameter flow-increasing radiator fin to solve the problem that the radiating fins mentioned in the above background technology cannot be replaced.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-diameter flow-increasing radiator, comprising a heat dissipation tube and heat dissipation fins mounted around the heat dissipation tube, wherein both ends of the heat dissipation fins are fixedly connected with mounting sleeves, both ends of the heat dissipation tube are provided with limiting grooves, and the mounting sleeves are located on the outside of the limiting grooves, retaining clips are symmetrically arranged in the mounting sleeves, and threaded rods are symmetrically arranged on the mounting sleeves, and one end of the threaded rods passes through the interior of the mounting sleeves and is connected with the retaining clips.

[0008] Furthermore, a connecting groove is provided on the retaining clip, and one end of the threaded rod is inserted into the connecting groove.

[0009] Furthermore, a groove is provided in the connection slot, a limit block is movably installed in the groove, and the limit block is fixedly connected to one end of the threaded rod.

[0010] Furthermore, a placement groove is provided on the inner side of the installation sleeve, and the retaining clip is located in the placement groove.

[0011] Furthermore, a rotating handle is fixedly mounted on one end of the threaded rod, and the rotating handle is concave-convex.

[0012] Furthermore, the installation sleeve is symmetrically provided with thread grooves, and one end of the thread groove extends into the placement groove, and the threaded rod is threadedly connected to the thread groove.

[0013] Furthermore, a positioning groove is arranged around the heat dissipation tube, and the positioning groove is wound from one end of the heat dissipation tube to the other end.

[0014] Furthermore, an arc-shaped slot is symmetrically arranged in the positioning slot, an arc-shaped protrusion is symmetrically arranged on one side of the heat dissipation fin, and the heat dissipation fin is installed in the positioning slot by snapping the arc-shaped protrusion with the arc-shaped slot.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model discloses to disassemble and assemble the heat dissipation fins quickly by setting the retaining clips. First, the heat dissipation tubes are inserted into the heat dissipation fins and the mounting sleeves at both ends of the heat dissipation fins are inserted into the heat dissipation fins and the mounting sleeves are moved to the limit grooves. Then, the threaded rod in the threaded groove is rotated by rotating the handle. The threaded rod rotates forward to push the retaining clip to move by rotating in the connecting groove. The retaining clip moves to the limit grooves and fixes the position of the heat dissipation fins by engaging with the limit grooves. Conversely, if the heat dissipation fins need to be disassembled, only the threaded rod needs to be rotated in the opposite direction and the retaining clips can be driven by the threaded rod to move out of the limit grooves. When the heat dissipation fins are damaged, only the heat dissipation fins need to be disassembled and replaced without replacing the entire heat dissipation tubes. The large-diameter flow-increasing radiator fins that are easy to replace save costs and reduce waste of resources, while reducing maintenance time and workload and improving maintenance efficiency.

[0017] 2. The utility model facilitates uniform distribution of the heat dissipation fins by setting the positioning grooves. First, the heat dissipation fins slidingly wrapped around the heat dissipation tubes are pressed hard to make the arc-shaped protrusions on the heat dissipation fins enter the positioning grooves and engage with the arc-shaped card grooves. Since the positioning grooves surround the heat dissipation tubes uninterruptedly from one end to the other end, it is only necessary to rotate the heat dissipation tubes to limit the engagement of the heat dissipation fins. The spacing and density of the heat dissipation fins are reasonably controlled to ensure that the gaps between the heat dissipation fins are sufficient to accommodate air flow. The large-diameter flow-increasing radiator improves the heat dissipation effect of the radiator. BRIEF DESCRIPTION OF THE DRAWINGS

The large-diameter radiator fin is installed on the heat pipe 1 in a wider and flatter shape, which increases the heat exchange area between the heat pipe 1 and the surrounding environment, and provides more heat dissipation surface for the radiator, but the existing heat dissipation fins 2 are usually welded. The heat pipe 1 cannot be disassembled. When the heat fin 2 is damaged, the entire heat pipe 1 needs to be replaced, which causes a waste of resources. When the heat fin 2 is disassembled and assembled, the heat fin 2 can be quickly disassembled and assembled by installing the retaining clip 22. First, the heat pipe 1 is inserted into the heat fin 2, and the installation sleeves 21 at both ends of the heat fin 2 are inserted. The installation sleeve 21 is moved to the limit groove 24, and then the threaded rod 23 in the threaded groove 212 is rotated by rotating the handle 231. The threaded rod 23 rotates forward to push the retaining clip 2 by rotating in the connecting groove 221. 2 moves, the retaining clip 22 moves to the limiting groove 24, and the heat sink 2 is fixed in position by engaging with the limiting groove 24. Conversely, if the heat sink 2 needs to be disassembled, it is only necessary to rotate the threaded rod 23 in the opposite direction, and the retaining clip 22 is driven by the threaded rod 23 to move out of the limiting groove 24. When the heat sink 2 is damaged, it is only necessary to disassemble and replace the heat sink 2, and there is no need to replace the entire heat sink 1. The large-diameter flow-increasing heat sink that is easy to replace saves costs and reduces waste of resources, while reducing maintenance time and workload, and improving maintenance efficiency.

[0028] Furthermore, a placement groove 211 is provided on the inner side of the installation sleeve 21 , and the retaining clip 22 is located in the placement groove 211 .

[0029] Furthermore, a rotating handle 231 is fixedly mounted on one end of the threaded rod 23 , and the rotating handle 231 is concave-convex, so that the threaded rod 23 can be easily rotated by rotating the rotating handle 231 .

[0030] Embodiment 2

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a large-diameter flow-increasing heat sink proposed by the utility model is another embodiment of the utility model compared to the first embodiment. A positioning groove 3 is arranged around the heat pipe 1, and the positioning groove 3 is wound from one end of the heat pipe 1 to the other end. An arc-shaped card groove 31 is symmetrically arranged in the positioning groove 3. An arc-shaped protrusion 32 is symmetrically arranged on one side of the heat dissipation fin 2, and the heat dissipation fin 2 is installed in the positioning groove 3 through the engagement connection between the arc-shaped protrusion 32 and the arc-shaped card groove 31. When the heat dissipation fins 2 are evenly arranged, the heat dissipation fins 2 are evenly distributed by installing the positioning groove 3. First, the heat dissipation fins 2 sliding around the heat dissipation tube 1 are pressed hard to make the heat dissipation fins 2 The arc-shaped protrusion 32 on the sheet 2 enters the positioning groove 3 and engages with the arc-shaped groove 31. Since the positioning groove 3 continuously surrounds from one end of the heat pipe 1 to the other end, it is only necessary to rotate the heat pipe 1 to limit the engagement of the heat dissipation fin 2, and the spacing and density of the heat dissipation fins 2 are reasonably controlled to ensure that the gap between the heat dissipation fins 2 is sufficient to accommodate air flow. The large-diameter flow-increasing heat sink sheet improves the heat dissipation effect of the radiator. Since the shapes of the arc-shaped groove 31 and the arc-shaped protrusion 32 are both semicircular arcs, and the arc-shaped protrusion 32 is a high-strength engineering plastic with certain elasticity and toughness, the arc-shaped protrusion 32 can be engaged with and separated from the arc-shaped groove 31 only by external force.

[0032] Working principle: When using this large-diameter flow-increasing heat sink, first, when disassembling and assembling the heat sink 2, the fixing clip 22 is installed to facilitate the quick disassembly and assembly of the heat sink 2. First, the heat sink 1 is inserted into the heat sink 2, and then the mounting sleeves 21 at both ends of the heat sink 2 are inserted. The mounting sleeve 21 is moved to the limit groove 24, and then the threaded rod 23 in the threaded groove 212 is rotated by rotating the handle 231. The threaded rod 23 rotates forward and pushes the fixing clip 22 to move by rotating in the connecting groove 221. The fixing clip 22 Move to the limit groove 24 and fix the position of the heat sink 2 by engaging with the limit groove 24. Conversely, if the heat sink 2 needs to be disassembled, it is only necessary to rotate the threaded rod 23 in the opposite direction to drive the retaining clip 22 to move out of the limit groove 24 through the threaded rod 23. When the heat sink 2 is damaged, it is only necessary to disassemble and replace the heat sink 2 without replacing the entire heat sink 1. The large-diameter flow-increasing radiator that is easy to replace saves costs and reduces waste of resources, while reducing maintenance time and workload and improving maintenance efficiency.

[0033] Finally, when the heat sink fins 2 are arranged evenly, the positioning grooves 3 are installed to facilitate the uniform distribution of the heat sink fins 2. First, press the heat sink fins 2 that are slid around the heat sink tube 1 with force, so that the arc-shaped protrusions 32 on the heat sink fins 2 enter the positioning grooves 3 and engage with the arc-shaped slots 31. Since the positioning grooves 3 extend continuously from one end of the heat sink 1 to the other end, it is only necessary to rotate the heat sink 1 to limit the heat sink fins 2. The spacing and density of the heat sink fins 2 are reasonably controlled to ensure that the gaps between the heat sink fins 2 are sufficient to accommodate air flow. The large-diameter flow-increasing radiator improves the heat dissipation effect of the radiator.

[0034] This is the working principle of this large-diameter flow-increasing radiator.
