Description

Technical Field

[0001] This utility model relates to the field of radiators, and in particular to a ring-shaped radiator. Background Technology

[0002] A ring-shaped heat sink is a heat dissipation device with a ring structure design. It is commonly used in electronic components or systems to improve heat dissipation efficiency and ensure that the equipment operates normally in high-temperature environments.

[0003] Electrically powered components experience some losses during operation, most of which are converted into heat. A ring-shaped heatsink is fixed to the surface of the component, and the heat generated is absorbed by the fins on the heatsink's outer shell. The heat from the fins is then dissipated through the air, aided by a cooling fan that accelerates airflow, thus completing the heat dissipation process. The fins of a ring-shaped heatsink are typically made of aluminum. Aluminum has a low density and good thermal conductivity, but its mechanical strength is relatively weak, making it prone to deformation under stress. The fins usually have thin walls and a large surface area. While this design helps improve heat dissipation performance, it also means that the thin-walled structure lacks sufficient rigidity under external forces, making it prone to bending or breakage. When subjected to external impact, the fins of a tuning fork ring-shaped heatsink deform under stress. Damaged fins lead to a significant decrease in heat dissipation efficiency, thus affecting the overall performance of the ring-shaped heatsink. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the fins of an annular radiator are impacted by external forces, they will deform under stress. Damage to the fins will lead to a significant decrease in heat dissipation efficiency, thereby affecting the performance of the annular radiator.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a ring-shaped radiator, including a shell, a plurality of fins on one side of the shell, a cooling fan at the upper end of the shell, and a reinforcing device on one side of the shell, the reinforcing device supporting and reinforcing the gaps between the fins through a reinforcing plate.

[0006] Preferably, the reinforcement device includes a bolt, a ring, a reinforcement plate, a square tube, and a support plate. The bolt is inserted into one side of the ring to connect with the outer shell. The reinforcement plate is disposed on one side of the ring and located at the fin gap to fit against the two fins. The square tube is located on one side of the reinforcement plate. The support plate is inserted into the square tube and its other end contacts the reinforcement plate.

[0007] Preferably, a magnet is provided on one side of the square tube, and an iron sheet is provided on one side of the support plate, which is used to be attracted by the magnet.

[0008] Preferably, the support plate has an extension plate on the side away from the square tube to increase the size of one side of the support plate.

[0009] Preferably, the support plate has a trapezoidal block on the side near the square tube to reduce the size of the support plate on the side near the square tube.

[0010] Preferably, a positioning ring is provided on one side of the outer shell to position the ring on the outer shell.

[0011] Preferably, the positioning ring has an inclined plate on the side away from the outer shell, and the opening size of the inclined plate on the side away from the positioning ring is smaller than the opening size of the positioning ring.

[0012] Preferably, the support plate has several anti-slip blocks on both sides to increase the friction on both sides of the support plate.

[0013] In summary, the beneficial effects of this utility model are as follows: By using reinforcement devices, the gaps between the fins can be reinforced, preventing the fins of the annular radiator from deforming under external impact and causing a significant decrease in heat dissipation efficiency, thereby improving the performance of the annular radiator.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Figures 1 to 6 The ring-shaped heat sink shown includes a housing 1, with several fins 2 on one side of the housing 1, a cooling fan 3 at the upper end of the housing 1, and a reinforcing device 4 on one side of the housing 1. The reinforcing device 4 uses a reinforcing plate 43 to support and reinforce the gaps between the fins 2. When powered components operate, they experience some losses, most of which are converted into heat. The ring-shaped heat sink is fixed to the surface of the powered components. The heat generated by the powered components is absorbed by the fins 2 on the surface of the heat sink housing 1, and the heat at the fins 2 is dissipated through the air. At this time, the cooling fan 3 accelerates the airflow, thus completing the heat dissipation of the powered components. When the fins 2 are in use, the reinforcing device 4 can reinforce and support the gaps between the fins 2.

[0020] Figures 1 to 6 The reinforcement device 4 shown includes a bolt 41, a ring 42, a reinforcement plate 43, a square tube 44, and a support plate 45. The bolt 41 is inserted into one side of the ring 42 to connect with the outer shell 1. The reinforcement plate 43 is disposed on one side of the ring 42 and is located at the gap between the fins 2 to fit against the two fins 2. The square tube 44 is located on one side of the reinforcement plate 43. The support plate 45 is inserted into the square tube 44 and its other end contacts the reinforcement plate 43.

[0021] Figures 1 to 6As shown, when using the fins 2 on the surface of the outer shell 1, the ring 42 is moved to fit against the outer shell 1. At this time, the reinforcing plate 43 fixed on one side of the ring 42 is located at the gap of the fins 2 and fits against the fins 2. Then, the bolt 41 is rotated to thread the bolt 41 through the ring 42 and the outer shell 1, thus completing the fixing of the positions of the ring 42 and the reinforcing plate 43. Then, the support plate 45 is inserted into the square tube 44 on one side of the reinforcing plate 43, and one side of the support plate 45 contacts the reinforcing plate 43, thus supporting the shape of the reinforcing plate 43. This completes the support and reinforcement of the fins 2. The materials of the ring 42, the reinforcing plate 43, the square tube 44, and the support plate 45 are the same as the fins 2, so they do not affect the heat dissipation of the fins 2. By using the reinforcement device 4, the gap of the fins 2 can be reinforced, preventing the fins 2 of the annular radiator from deforming under external impact, which would lead to a significant decrease in heat dissipation efficiency, thereby improving the performance of the annular radiator.

[0022] Figures 1 to 6 A magnet 46 is provided on one side of the square tube 44, and an iron sheet 47 is provided on one side of the support plate 45, both of which are attracted by the magnet 46. The magnet 46 fixed on one side of the square tube 44 attracts the iron sheet 47 fixed on the other side of the support plate 45, making the support plate 45 more firmly positioned inside the square tube 44, thus improving the performance of the support plate 45. The magnet 46 and iron sheet 47 are relatively small and do not significantly affect heat dissipation. An extension plate 48 is provided on the side of the support plate 45 away from the square tube 44 to increase the size of that side. By fixing the extension plate 48 to the side of the support plate 45 away from the square tube 44, the size of that side of the support plate 45 is increased, allowing the support plate 45 to better contact the reinforcing plate 43, thereby improving the performance of the support plate 45. Furthermore, the extension plate 48 is made of the same material as the fins 2 and does not affect the heat dissipation of the fins 2.

[0023] Figures 1 to 6 The support plate 45 shown has a trapezoidal block 49 on the side near the square tube 44 to reduce the size of that side. The trapezoidal block 49 is fixed to the support plate 45 near the square tube 44, and the trapezoidal block 49 is smaller on the side away from the support plate 45, further reducing the size of that side and making it easier to insert the support plate 45 into the square tube 44. A positioning ring 410 is provided on one side of the outer casing 1 to position the ring 42 on the outer casing 1. The positioning ring 410 is fixed to one side of the outer casing 1 to quickly position the ring 42 and the outer casing 1, facilitating subsequent fixing of the ring 42 with bolts 41. Furthermore, the trapezoidal block 49 and the positioning ring 410 are made of the same material as the fins 2, so they do not affect the heat dissipation of the fins 2.

[0024] Figures 1 to 6The positioning ring 410 shown has a sloping plate 411 on the side away from the outer casing 1. The opening size of the sloping plate 411 on the side away from the positioning ring 410 is smaller than the opening size of the positioning ring 410. The sloping plate 411 reduces the size of the upper end of the positioning ring 410, making it easier for the ring 42 to fit onto the surface of the positioning ring 410, thereby improving the performance of the positioning ring 410. Several anti-slip blocks 412 are provided on both sides of the support plate 45 to increase the friction on both sides of the support plate 45. By fixing several anti-slip blocks 412 on both sides of the support plate 45, the friction on both sides of the support plate 45 is increased, making it easier to move the support plate 45. Furthermore, the sloping plate 411 and the anti-slip blocks 412 are made of the same material as the fins 2, and do not affect the heat dissipation of the fins 2.

[0025] Working principle: When powered components are in operation, they all have certain losses, most of which are converted into heat. The ring-shaped heat sink is then fixed to the surface of the powered components. The heat generated by the powered components is absorbed by the fins 2 on the surface of the heat sink shell 1. The heat at the fins 2 is dissipated through the air. At this time, the cooling fan 3 accelerates the air circulation, thus completing the heat dissipation of the powered components. When the fins 2 are in use, the reinforcement device 4 is used to reinforce and support the gaps between the fins 2. When using the fins 2 on the surface of the outer shell 1, move the ring 42 so that the ring 42 fits against the outer shell 1. At this time, the reinforcing plate 43 fixed on one side of the ring 42 is located at the gap of the fins 2 and fits against the fins 2. Then rotate the bolt 41 so that the bolt 41 passes through the ring 42 and is threadedly fixed to the outer shell 1. Then the positions of the ring 42 and the reinforcing plate 43 are fixed. Then the support plate 45 is inserted into the square tube 44 on one side of the reinforcing plate 43, and one side of the support plate 45 contacts the reinforcing plate 43. Then the shape of the reinforcing plate 43 is supported, and the support and reinforcement of the fins 2 are completed. The materials of the reinforcing plate 43 and the support plate 45 are the same as the fins 2, so they do not affect the heat dissipation of the fins 2. By using the reinforcement device 4, the gap of the fins 2 can be reinforced, so as to prevent the fins 2 of the annular heat sink from deforming under external impact, which would lead to a significant decrease in heat dissipation efficiency, thereby improving the performance of the annular heat sink.
