Description

Technical Field

[0001] This utility model relates to the field of aluminum heat sinks, specifically a removable aluminum heat sink. Background Technology

[0002] A heat sink is a device used to dissipate heat from electronic components in electrical appliances. They are typically made of aluminum alloy, brass, or bronze, and can be plate-shaped, sheet-shaped, or multi-sheet-shaped. For example, the CPU in a computer requires a fairly large heat sink, and heat sinks are also used for power transistors, horizontal output transistors, and power amplifier transistors in a television. Generally, a layer of thermal grease is applied to the contact surface between the electronic component and the heat sink during use, allowing the heat generated by the component to be more effectively conducted to the heat sink and then dissipated into the surrounding air. Among the many types of heat sinks, aluminum heat sinks are favored for their aesthetic appearance, light weight, good heat dissipation performance, and energy-saving effect.

[0003] The heat sinks used today are usually a single unit, fixed to the device with screws. When one of the heat sinks is damaged, it is not possible to replace the individual heat sink; the entire device must be replaced, resulting in high costs. Some heat dissipation devices that allow individual heat sink replacements have a cumbersome replacement process, making them inconvenient to use.

[0004] Therefore, a removable aluminum heat sink is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems that when one heat sink is damaged, it is impossible to replace the individual heat sink, and only the whole heat sink can be replaced, resulting in high costs, and some heat dissipation devices that can replace heat sinks individually have a cumbersome replacement method, resulting in inconvenience in use, this utility model proposes an easily detachable aluminum heat sink.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a detachable aluminum heat sink, including a mounting base, a screw hole inside the mounting base, a first mounting component on the top of the mounting base, the first mounting component including a mounting seat fixedly connected to the top of the mounting base, a placement groove inside the mounting seat, a mounting groove inside the mounting seat, a first rotating shaft fixedly connected inside the mounting groove, a first locking block rotatably connected to the outside of the first rotating shaft, and a first torsion spring fixedly connected between the first locking block and the mounting seat.

[0007] Preferably, an adjustment component is provided on the outside of the mounting base. The adjustment component includes a slide groove formed inside the mounting base, a screw fixedly connected inside the slide groove, a slide seat slidably connected to the outside of the screw, and a slider fixedly connected to the outside of the slide seat. The outside of the slider is slidably connected to the inside of the mounting base.

[0008] Preferably, the adjustment assembly further includes two mounting plates fixedly connected to the top of the sliding seat, a limit block fixedly connected to the top of the sliding seat, and a nut rotatably connected to the outside of the sliding seat, the nut being threadedly connected to the outside of the screw.

[0009] Preferably, a second mounting component is provided on the outer side of the mounting plate. The second mounting component includes a second rotating shaft fixedly connected between the two mounting plates, a second locking block rotatably connected to the outer side of the second rotating shaft, and a second torsion spring fixedly connected between the second locking block and the mounting plate.

[0010] Preferably, a cooling assembly is provided on the outside of the mounting base. The cooling assembly includes a heat sink slidably connected to the inside of the placement slot. Two slots are formed inside the heat sink, and the two slots are slidably connected to the outside of the first and second blocks, respectively.

[0011] Preferably, the interior of the mounting base abuts against the exterior of the first locking block, and the height of the bottom of the placement groove is flush with the height of the bottom of the inner cavity of the first and second locking blocks.

[0012] Preferably, the outer side of the second locking block abuts against the outer side of the limiting block, and the bottom of the second locking block abuts against the top of the sliding seat.

[0013] The advantages of this utility model are: 1. This utility model uses the downward pressure of the heat sink to drive the first locking block to rotate along the first rotating shaft and cause the first torsion spring to operate. When the bottom of the heat sink abuts against the bottom of the placement slot cavity, the first locking block will enter the slot, thereby fixing the position of the heat sink and completing the replacement of the heat sink. This replacement method can reduce the time required to replace the heat sink and improve the convenience of using the device.

[0014] 2. This utility model uses the rotation of the nut to move the sliding seat, which in turn moves the second mounting component, thus adapting to heat sinks of different sizes and improving the adaptability of the device. Attached Figure Description

[0018] 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.

[0019] Example 1 Please see Figure 1-4 As shown, a removable aluminum heat sink includes a mounting base 1 with a screw hole 2 inside. A first mounting component is provided on the top of the mounting base 1. The first mounting component includes a mounting seat 3 fixedly connected to the top of the mounting base 1. A placement groove 4 and a mounting groove 5 are provided inside the mounting seat 3. A first rotating shaft 6 is fixedly connected inside the mounting groove 5. A first locking block 7 is rotatably connected to the outside of the first rotating shaft 6. A first torsion spring 8 is fixedly connected between the first locking block 7 and the mounting seat 3.

[0020] During operation, the downward pressure of the heat sink 19 causes the first locking block 7 to rotate along the first rotating shaft 6, and the first torsion spring 8 to operate. When the bottom of the heat sink 19 abuts against the bottom of the inner cavity of the placement slot 4, the first locking block 7 will enter the slot 20, thereby fixing the position of the heat sink 19 and completing the replacement of the heat sink 19. This replacement method can reduce the time required to replace the heat sink 19, thereby improving the convenience of using the device.

[0021] The mounting plate 13 has a second mounting component on its outer side. The second mounting component includes a second rotating shaft 14 fixedly connected between the two mounting plates 13. A second locking block 15 is rotatably connected to the outer side of the second rotating shaft 14. A second torsion spring 16 is fixedly connected between the second locking block 15 and the mounting plate 13.

[0022] During operation, the downward pressure of the heat sink 19 causes the second locking block 15 to rotate along the second rotating shaft 14, and the second torsion spring 16 to operate. When the bottom of the heat sink 19 abuts against the bottom of the inner cavity of the placement slot 4, the second locking block 15 will enter the slot 20, thereby fixing the position of the heat sink 19, thus completing the installation and replacement of the heat sink 19, reducing the time required to replace the heat sink 19, and improving the ease of use of the device.

[0023] The mounting base 3 is provided with a cooling component on its outer side. The cooling component includes a heat sink 19 that is slidably connected to the inside of the placement slot 4. The heat sink 19 has two slots 20 inside, and the two slots 20 are slidably connected to the outer side of the first block 7 and the second block 15, respectively.

[0024] During operation, the slot 20 cooperates with the first card block 7 and the second card block 15 respectively to fix the position of the heat sink 19, thereby facilitating the replacement of the heat sink 19.

[0025] The mounting base 3 is in contact with the outside of the first locking block 7, and the bottom of the inner cavity of the placement groove 4 is level with the bottom of the inner cavity of the first locking block 7 and the second locking block 15.

[0026] During operation, the rotation range of the first locking block 7 can be limited by the mounting base 3.

[0027] The outer side of the second locking block 15 abuts against the outer side of the limiting block 17, and the bottom of the second locking block 15 abuts against the top of the sliding seat 11.

[0028] During operation, the position of the second locking block 15 can be restricted by the limiting block 17, and the position of the second locking block 15 can also be restricted by the sliding seat 11.

[0029] Example 2 Please see Figure 5As shown in the first embodiment, as another implementation of this utility model, an adjustment component is provided on the outside of the mounting base 3. The adjustment component includes a slide groove 9 opened inside the mounting base 3. A screw 10 is fixedly connected inside the slide groove 9. A sliding seat 11 is slidably connected to the outside of the screw 10. A slider 12 is fixedly connected to the outside of the sliding seat 11. The outside of the slider 12 is slidably connected to the inside of the mounting base 3.

[0030] The adjustment assembly also includes two mounting plates 13 fixedly connected to the top of the sliding seat 11, a limit block 17 fixedly connected to the top of the sliding seat 11, and a nut 18 rotatably connected to the outside of the sliding seat 11. The nut 18 is threadedly connected to the outside of the screw 10.

[0031] During operation, rotating the nut 18 moves the sliding seat 11, which in turn moves the second mounting component, thus accommodating heat sinks 19 of different sizes and improving the adaptability of the device.

[0032] The working principle is that by pressing down the heat sink 19, the first locking block 7 is driven to rotate along the first rotating shaft 6, and the first torsion spring 8 is activated. When the bottom of the heat sink 19 abuts against the bottom of the inner cavity of the placement slot 4, the first locking block 7 will enter the slot 20, thereby fixing the position of the heat sink 19 and completing the replacement of the heat sink 19. This replacement method can reduce the time required to replace the heat sink 19, thereby improving the convenience of using the device.
