Description

Technical Field

[0001] This utility model relates to the field of thermal management technology, and in particular to a heat sink that is easy to install. Background Technology

[0002] A heat sink is a thermal management component that increases heat exchange area to improve heat dissipation efficiency. It is widely used in electronic equipment, power systems, and industrial machinery. Through the thermal conductivity of the metal substrate and the convection design of the finned structure, it rapidly transfers heat generated by the heat-generating element to the external environment, ensuring stable operation of the equipment within a safe temperature range. With the continuous increase in the power density of electronic devices, the heat dissipation performance and ease of installation of heat sinks have become key factors restricting the integration and reliability of equipment.

[0003] Most current mainstream heat sinks are installed using mechanical fastening structures. Screw holes are pre-drilled on both sides of the heat sink substrate, and the heat sink is pressed onto the heat source surface or equipment base using bolts and nuts or self-tapping screws. During installation, screwdrivers, electric screwdrivers, or other tools are needed to tighten the bolts sequentially into the screw holes on both sides of the heat sink. During this process, the operator must accurately align the holes and ensure that the bolts fully engage with the threads of the screw holes. Finally, sufficient contact pressure is generated through tightening torque to reduce thermal resistance.

[0004] However, existing screw fixing methods have significant installation defects. Because the screw holes are distributed on both sides of the heatsink, the tool can only rotate about half a turn in one direction before being blocked by the heatsink body. This requires repeated adjustments to the tool angle or multiple insertions and removals of the tool to complete the full tightening operation. This "half-turn" operation mode not only prolongs the installation time of a single screw, but also increases the risk of operator fatigue and accidental contact in confined spaces or high-density heat dissipation module scenarios. Utility Model Content

[0005] To overcome the disadvantages of limited operation, this utility model provides a heat sink that is easy to install, aiming to solve the above-mentioned shortcomings.

[0006] An easy-to-install heat sink includes a heat sink, a mounting bracket, a pressure plate, fixing screws, and a stabilizing component. The mounting bracket has through holes corresponding to the installation position. The heat sink is slidably connected to the mounting bracket and the component to be cooled on both sides. Fixing screws are threaded to both sides of the mounting bracket. A pressure plate is slidably connected inside the mounting bracket. The ends of the fixing screws are rotatably connected to the pressure plate. The pressure plate and the heat sink are pressed together. A stabilizing component for supporting the heat sink is provided at the bottom of the mounting bracket.

[0007] Furthermore, it is particularly preferred that the stabilizing component includes a top plate, a locking block, and a return spring. The top plate is slidably connected to the lower part of the mounting frame, and the top plate has several vertically distributed locking slots. The locking block is slidably connected to the lower end of the mounting frame, and the end of the locking block passes through the mounting frame and is slidably connected to the top plate. The locking block is fitted with a return spring, one end of which is connected to the locking block, and the other end of which is connected to the mounting frame.

[0008] Furthermore, it is particularly preferred that an auxiliary rod is also included, with the auxiliary rod connected to the front side of the locking block.

[0009] In addition, it is particularly preferred that a protective pad is also included, with the top surface of the top plate connected to the protective pad, and the heat sink and the protective pad are pressed together.

[0010] In addition, it is particularly preferred that a rubber pad is also included, with the side of the pressure plate that contacts the heat sink connected to the rubber pad.

[0011] Furthermore, it is particularly preferred that the mounting bracket also includes a baffle, which is connected to the mounting bracket to isolate the fixing screws and the heat sink.

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

[0013] 1. The sliding connection structure between the mounting bracket and the heat sink allows the heat sink to move vertically along the guide groove of the mounting bracket on both sides, enabling the installation tool to rotate around the entire circumference, shortening the installation time of a single screw and improving installation efficiency.

[0014] 2. The elastic support of the stabilizing components and the locking mechanism of the slots ensure that the heat sink maintains a stable height during installation, preventing scratches against the edge of the mounting bracket, reducing the risk of coating wear, thread stripping, and heat sink deformation, and enhancing operational safety and equipment reliability.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] Example: An easy-to-install heat sink, such as Figures 1-4 As shown, the device includes a heat sink 1, a mounting bracket 2, a pressure plate 3, fixing screws 4, and a stabilizing component. The mounting bracket 2 has through holes that match the mounting positions. The two sides of the heat sink 1 are slidably connected between the mounting bracket 2 and the heat dissipation component. Each of the left and right sides of the mounting bracket 2 is threaded with a fixing screw 4. The pressure plate 3 is slidably installed inside the mounting bracket 2. The ends of the fixing screws 4 are rotatably connected to the pressure plate 3. The pressure plate 3 and the heat sink 1 are in a compression fit relationship. A stabilizing component for supporting the heat sink 1 is installed at the bottom of the mounting bracket 2.

[0022] like Figure 2 and Figure 4 As shown, the stabilizing component includes a top plate 5, a locking block 7, and a return spring 8. The top plate 5 is slidably mounted on the lower part of the mounting bracket 2. The top plate 5 has six slots 6 arranged vertically. The locking block 7 is slidably connected to the lower end of the mounting bracket 2. The end of the locking block 7 passes through the mounting bracket 2 and is slidably connected to the top plate 5. The return spring 8 is fitted on the locking block 7. One end of the return spring 8 is connected to the locking block 7, and the other end is connected to the mounting bracket 2. The surface of the top plate 5 is coated with a high-temperature resistant coating. The return spring 8 is made of a high-temperature resistant alloy material to ensure structural stability in high-temperature environments, extend service life, adapt to high-temperature working environments, and ensure long-term stable support for the heat sink 1.

[0023] like Figure 2 and Figure 4 As shown, it also includes an auxiliary rod 9. The front side of the locking block 7 is connected to the auxiliary rod 9. The end of the auxiliary rod 9 is provided with an ellipsoidal head, which facilitates hand gripping and operation, prevents slippage, and improves grip stability.

[0024] like Figure 2 and Figure 4 As shown, it also includes a protective pad 10. The top surface of the top plate 5 is connected to the protective pad 10. The heat sink 1 is pressed and fitted with the protective pad 10. The protective pad 10 is made of high temperature resistant rubber material, which is elastic and resistant to aging, and can provide effective cushioning to reduce wear between the heat sink 1 and the top plate 5.

[0025] likeFigure 3 As shown, it also includes a rubber pad 11. The side of the pressure plate 3 that contacts the heat sink 1 is connected to the rubber pad 11. The rubber pad 11 is made of high temperature resistant silicone material, which has good compression deformation ability and resilience, and can provide uniform clamping force to prevent the heat sink 1 from loosening.

[0026] like Figure 1 and Figure 2 As shown, it also includes a baffle 12. The mounting bracket 2 is connected to the baffle 12 for isolating the fixing screw 4 and the heat sink 1. The baffle 12 is made of heat-insulating ceramic material, which effectively blocks the heat of the fixing screw 4 from being conducted to the heat sink 1, avoids local overheating, improves the overall heat dissipation efficiency, and extends the service life of the equipment.

[0027] The operator first tightly attaches the heat sink 1 to the surface of the component to be cooled, ensuring no gaps in the contact surface. Then, the through-hole of the mounting bracket 2 is precisely aligned with the threaded hole of the component to be cooled, and both ends of the heat sink 1 are smoothly inserted into the guide groove of the mounting bracket 2. The heat sink 1 slides vertically down the guide groove of the mounting bracket 2 on both sides. When the bottom contacts the top plate 5, the protective pad 10 undergoes elastic deformation due to pressure, forming a buffer layer to reduce wear on the bottom of the heat sink 1. At this point, a suitable gap is maintained between the top of the heat sink 1 and the top through-hole of the mounting bracket 2.

[0028] Next, tighten the fixing screws 4 on both sides of the upper end of the mounting bracket 2 to initially press the top of the mounting bracket 2 against the surface of the component to be cooled. The top of the heat sink 1 is slightly raised due to the support of the top plate 5 to avoid interference with the top of the mounting bracket 2 during subsequent operations. Then, pull the locking block 7 outward by the auxiliary rod 9. The return spring 8 is stretched, and the end of the locking block 7 disengages from the slot 6 of the top plate 5. At this time, push the top plate 5 upward, causing the heat sink 1 to move upward synchronously within the mounting bracket 2. After the bottom of the heat sink 1 moves above the bottom through hole of the mounting bracket 2, release the auxiliary rod 9. The return spring 8 rebounds and pushes the locking block 7 back into the slot 6, forming a locking structure to keep the top plate 5 and the heat sink 1 at the current height.

[0029] Then tighten the fixing screws 4 on both sides of the lower end of the mounting bracket 2 to complete the fixation of the mounting bracket 2 to the component to be cooled. At this time, the position of the heat sink 1 is maintained by the top plate 5 and the locking block 7, and the bottom maintains stable contact with the surface of the component to be cooled. Pull the locking block 7 outward by the auxiliary rod 9 so that the end of the locking block 7 is disengaged from the slot 6. Manually adjust the longitudinal position of the heat sink 1 to ensure that it is completely attached to the surface of the component to be cooled without any deviation. The top plate 5 continues to provide support for the bottom of the heat sink 1. When the fixing screws 4 on both sides of the mounting bracket 2 are screwed in, the ends of the screws push the pressure plate 3 to press against the side wall of the heat sink 1. The rubber pad 11 on the surface of the pressure plate 3 is compressed and undergoes elastic deformation, forming a uniform clamping force to ensure that the heat sink 1 is firmly fixed laterally, thus completing the installation process.

[0030] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
