Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to an installation structure of a special-shaped CPC heat sink which is easy to disassemble and assemble. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the shape of plates, sheets, or multiple sheets. For example, a computer's CPU central processing unit requires a fairly large heat sink, as do the power tubes and line tubes in televisions, and the power amplifier tubes in amplifiers.

[0003] After searching, the patent number is CN218631406U, and the name is a utility model for a heat sink for a hard disk backplane, including a substrate and fins. The substrate is installed on the hard disk backplane, and the fins are installed on the substrate. Through research and analysis, it is found that although the installation problem of the heat sink and the structural interference problem have been solved, the following defects still exist to a certain extent.

[0004] For example, it is inconvenient to disassemble and assemble the heat sink. During the installation process, personnel need to use tools and screws to install the heat sink on the electrical components. The operation is time-consuming and labor-intensive, and the disassembly and assembly efficiency is low, which increases the labor intensity of personnel. At the same time, the fan cannot be vibrated. Since the fan will generate frequent vibrations during operation, after the vibrations are transmitted to the electrical components, it is easy for the components to loosen and cause failures, thus affecting the service life. In order to solve the above technical problems, we have designed an installation structure for a special-shaped CPC heat sink that is easy to disassemble and assemble. Utility Model Content

[0005] The utility model aims to provide an installation structure for a special-shaped CPC heat sink that is easy to disassemble and assemble, which has the advantages of being convenient for disassembling and assembling the heat sink, improving disassembly and assembly efficiency, reducing labor intensity of personnel, having a vibration reduction function, and reducing the failure rate of electrical components, thereby solving the problem that disassembling and assembling the heat sink is time-consuming and laborious, increases labor intensity of personnel, has no vibration reduction function, and increases the failure rate of electrical components.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an installation structure of a special-shaped CPC heat sink that is easy to disassemble and assemble, comprising a connecting plate, positioning mechanisms are welded on the left and right sides of the top of the connecting plate, a shock-absorbing base is fixedly connected to the front and rear sides of the top of the connecting plate, a cooling fan is connected to the top of the shock-absorbing base by bolts, a mounting base is plugged into the top of the connecting plate, cooling fins are welded on the top of the mounting base, and positioning grooves are provided on the front and rear sides of the left and right sides of the mounting base.

[0007] Preferably, the positioning mechanism includes a fixed shell, the inner cavities on the front and rear sides of the fixed shell are slidably connected to support sliders, the inner side of the support slider is fixedly connected to a positioning spring, the outer side of the support slider is fixedly connected to a positioning pin, and the side of the positioning pin away from the support slider penetrates to the outside of the fixed shell and is chamfered.

[0008] Preferably, sliding openings are provided on both the front and rear sides of the outer side of the fixed shell, and the opposite sides of the left and right supporting sliding blocks penetrate to the outer sides of the sliding openings and are fixedly connected with push plates.

[0009] Preferably, the shock-absorbing base includes a base shell, dampers are fixedly connected to the left and right sides of the bottom of the inner cavity of the base shell, the top of the damper is fixedly connected to a connecting slide, the top and bottom of the connecting slide are fixedly connected to shock-absorbing springs, the left and right sides and the middle of the top of the connecting slide are fixedly connected to supporting vertical rods, and the top of the supporting vertical rods passes through the top of the base shell and is fixedly connected to a supporting cross plate.

[0010] Preferably, mounting holes are provided at four corners of the top of the connecting plate, and ventilation holes are provided at the bottom of the surface of the heat dissipating fins.

[0011] Preferably, the four corners of the top of the connecting plate are welded with limit baffles, and the front and rear sides of the cooling fan are fixedly connected with protective nets.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. Press the installation base plate downward with force. After the bottom of the installation base plate is completely in contact with the connecting plate, the positioning spring pushes the positioning pin outward and inserts it into the positioning groove, pushes the push plates on both sides inward, and moves out of the positioning groove through the supporting slider, and pulls the heat sink fin upward. Disassembly and assembly are more convenient and quick, and personnel do not need to operate by using tools, which reduces the labor intensity of personnel and improves the efficiency of disassembly and assembly.

[0014] 2. The cooling fan works to dissipate heat to the middle cooling fins. The kinetic energy generated by the vibration is transferred to the connecting slide, pushing the vibration-damping springs on the upper and lower sides to compress. During the compression process, the vibration-damping springs can offset the kinetic energy and reduce the transmission of vibration. This can prevent electrical components from loosening due to vibration, reduce the failure rate and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 5 , a mounting structure of a special-shaped CPC heat sink that is easy to disassemble and assemble, comprising a connecting plate 1, a positioning mechanism 4 is welded on both the left and right sides of the top of the connecting plate 1, a damping base 17 is fixedly connected to both the front and rear sides of the top of the connecting plate 1, a cooling fan 7 is connected to the top of the damping base 17 by bolts, a mounting base 3 is plugged into the top of the connecting plate 1, a cooling fin 8 is welded on the top of the mounting base 3, and positioning grooves 15 are opened on both the front and rear sides of the left and right sides of the mounting base 3;

[0022] See also Figure 3 The positioning mechanism 4 includes a fixed shell 12, and the inner cavities on both sides of the fixed shell 12 are slidably connected with the support slider 10, the inner side of the support slider 10 is fixedly connected with a positioning spring 11, and the outer side of the support slider 10 is fixedly connected with a positioning pin 9. The side of the positioning pin 9 away from the support slider 10 penetrates to the outer side of the fixed shell 12 and is chamfered. By setting the chamfer, the positioning pin 9 can be easily inserted into the positioning groove 15;

[0023] See also Figure 3 The front and rear sides of the outer side of the fixed shell 12 are both provided with sliding openings 13, and the opposite sides of the left and right supporting slide blocks 10 penetrate to the outer side of the sliding openings 13 and are fixedly connected with push plates 14. By setting the push plates 14, it is possible for personnel to push the positioning pins 9 with more effort;

[0024] See also Figure 5The shock absorbing base 17 includes a base shell 21. The left and right sides of the bottom of the inner cavity of the base shell 21 are fixedly connected with dampers 18. By setting the damper 18, it is possible to provide resistance to movement and consume movement energy, thereby reducing or eliminating vibration and impact, and avoiding unnecessary vibration of the cooling fan 7. The top of the damper 18 is fixedly connected with a connecting slide 20. The top and bottom of the connecting slide 20 are fixedly connected with a vibration-damping spring 19. The left and right sides and the middle of the top of the connecting slide 20 are fixedly connected with supporting vertical rods 22. The top of the supporting vertical rod 22 penetrates to the top of the base shell 21 and is fixedly connected with a supporting horizontal plate 23.

[0025] See also Figure 1 The four corners of the top of the connecting plate 1 are provided with mounting holes 2. By providing the mounting holes 2, the connecting plate 1 can be conveniently installed on the electrical components that need heat dissipation. The bottom of the surface of the heat dissipation fin 8 is provided with a vent 5. By providing the vent 5, the heat dissipation wind can flow out from the heat dissipation fin 8, thereby improving the heat dissipation efficiency.

[0026] See also Figure 1 The four corners of the top of the connecting plate 1 are welded with limit baffles 6, and the front and rear sides of the cooling fan 7 are fixedly connected with protective nets 16. By setting the protective nets 16, the cooling fan 7 can be protected to prevent debris from entering the interior.

[0027] When in use, align the four corners of the mounting base plate 3 with the limit baffles 6 at the four corners respectively, and press downward with force. During the downward movement of the mounting base plate 3, the positioning pins 9 on both sides are pushed toward the inner cavity of the fixed shell 12. When the bottom of the mounting base plate 3 is completely in contact with the connecting plate 1, the compressed positioning spring 11 releases its elastic potential energy to push the positioning pin 9 outward and insert it into the positioning groove 15 through the supporting slider 10, so that the heat sink can be fixedly installed. When it needs to be disassembled, push the push plates 14 on both sides inward, and the push plates 14 are driven to move out of the positioning groove 15 through the supporting slider 10, and then pull the heat dissipating fins 8 upward, so that the heat sink can be removed from the connecting plate 1, and the disassembly and assembly is more convenient. It is more convenient and quick, and does not require personnel to operate by using tools, which reduces the labor intensity of personnel and improves the efficiency of disassembly and assembly. After the cooling fans 7 on both sides are powered on, the wind is blown to the middle cooling fins 8 to quickly dissipate the heat. Since the cooling fans 7 will vibrate during operation, the kinetic energy generated by the vibration is transmitted to the connecting slide 20. The connecting slide 20 pushes the vibration-damping springs 19 on the upper and lower sides to be compressed. The vibration-damping springs 19 can offset the kinetic energy and reduce the transmission of vibration during the compression process. In this way, the vibration can be prevented from being transmitted to the contacting electrical components through the connecting plate 1. In this way, the electrical components can be prevented from becoming loose due to vibration, thereby reducing the failure rate and extending the service life.

[0028] In summary, the installation structure of the special-shaped CPC heat sink that is easy to disassemble and assemble solves the problems of time-consuming and labor-intensive disassembly and assembly of the heat sink, increased labor intensity, lack of vibration reduction function, and increased failure rate of electrical components through the coordinated use of the connecting plate 1, the mounting base plate 3, the positioning mechanism 4, the heat dissipation fan 7, the heat dissipation fins 8, the positioning grooves 15 and the shock-absorbing base 17.
