Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat sink technology, and in particular to an adjustable clamping heat sink. Background Technology
[0002] Heat sinks are typically made of metal and consist of a substrate and fixedly arranged heat dissipation fins, increasing heat dissipation efficiency by increasing surface area. Clamp-on heat sinks use a metal substrate with a fixed clamping structure, pressing them onto the surface of electronic components using spring clips or bolts for heat dissipation. While these heat sinks are easier to install and remove than adhesive-on types, they still have significant drawbacks: their clamping mechanisms are often designed with fixed spacing, only suitable for components of specific sizes, resulting in poor versatility; rigid clamping can easily lead to uneven contact pressure, potentially affecting heat conduction efficiency due to insufficient pressure, or damaging precision components due to excessive pressure. These structural defects make them unsuitable for the diverse and high-reliability heat dissipation requirements of modern electronic equipment, especially performing poorly in harsh environments such as automotive and industrial applications. Utility Model Content
[0003] The main purpose of this invention is to provide an adjustable clamping heat sink, which is designed to adjust the spacing between the clamping structures to accommodate electronic components of different sizes.
[0004] To achieve the above objectives, this utility model proposes an adjustable clamping heat sink, comprising:
[0005] A base plate having a heat dissipation surface and a bonding surface, wherein multiple wing plates are vertically arranged on the heat dissipation surface and the multiple wing plates are arranged in parallel at equal intervals.
[0006] Two clamping plates are vertically disposed on the mating surface of the base plate. The clamping plates are movably connected to the edge of the base plate and can be moved to change the distance between the two clamping plates.
[0007] In one possible implementation, the base plate has a long side and a short side, the wing plate is arranged parallel to the short side, and the length of the short side is greater than the length of the wing plate.
[0008] In one possible implementation, both ends of the clamping plate near the base plate are bent to form hook-shaped portions, which are attached to the edge of the heat dissipation surface of the base plate.
[0009] In one possible implementation, stop strips are detachably connected to both sides of the heat dissipation surface of the base plate to prevent the hook-shaped portion from sliding out from both sides of the base plate.
[0010] In one possible implementation, the clamping plate has fixing holes on its surface.
[0011] This utility model's technical solution employs a base plate design with a wing-plate structure. The wing plates are arranged parallel to the short side at equal intervals, working in conjunction with airflow channels to achieve highly efficient heat dissipation. Two clamping plates are attached to the edge of the base plate via hook-like parts, and their spacing can be adjusted by sliding along the long side to accommodate electronic components of different sizes. A stop bar design prevents the clamping plates from falling off, ensuring safe use. Fixing holes on the surface of the clamping plates support various fixing methods such as screws and locating pins, providing additional stability. This combined design retains the heat dissipation efficiency of traditional heat sinks while significantly improving versatility and ease of installation through the adjustable clamping structure. The overall solution solves the problems of poor compatibility and inconvenient installation of traditional heat sinks, making it particularly suitable for applications requiring frequent component replacement or high heat dissipation stability, such as industrial equipment, high-power electronic components, and test fixtures. This heat sink offers comprehensive advantages such as flexible installation, safe use, and convenient maintenance while ensuring excellent heat dissipation performance. Attached Figure Description

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0019] Reference Figures 1 to 2This utility model proposes an adjustable clamping heat sink, including a base plate 1 and two clamping plates 3. The base plate 1 has a heat dissipation surface 11 and a contact surface 12. Multiple wing plates 2 are vertically arranged on the heat dissipation surface 11 and are arranged in parallel at equal intervals. The two clamping plates 3 are vertically arranged on the contact surface 12 of the base plate 1 and are movably connected to the edge of the base plate 1. The clamping plates 3 can be moved to change the distance between the two clamping plates 3.
[0020] Understandably, the base plate 1 is divided into two functional surfaces. The heat dissipation surface 11 has multiple wing plates 2 vertically mounted on it. These wing plates 2 are arranged in an equidistant and parallel manner to form dense heat dissipation fins, which improve heat dissipation efficiency by increasing the surface area. At the same time, the regular arrangement ensures that the airflow passes through evenly. The contact surface 12 is used to contact the object being dissipated, ensuring that the heat is conducted from the object to the base plate 1.
[0021] Two clamping plates 3 are vertically fixed to the edge of the mating surface 12 of the base plate 1 and can move via movable connections such as slide rails, hinges, or elastic mechanisms. Users can adjust the position of the clamping plates 3 to change the distance between them, thereby adapting to objects of different sizes. This design solves the problem of poor compatibility of traditional heat sinks and is especially suitable for devices that require frequent replacement or have variable sizes.
[0022] Reference Figure 1 In one embodiment of the present invention, the base plate 1 has a long side 13 and a short side 14, the wing plate 2 is arranged parallel to the short side 14, and the length of the short side 14 is greater than the length of the wing plate 2.
[0023] Understandably, the wing plate 2 is parallel to the short side 14, ensuring that its length direction is perpendicular to the long side 13 of the base plate 1, thereby maximizing the heat dissipation surface area 11 within a limited space. The length of the wing plate 2 is shorter than the total length of the short side 14 of the base plate 1. This design leaves blank areas at both ends of the long side 13 that do not cover the wing plate 2, providing physical space for the installation and movement of the clamping plate 3. Since the clamping plate 3 is installed at the edge of the long side 13, its movement direction is parallel to the long side 13, making the spacing adjustment of the two clamping plates 3 more stable and not interfering with the heat dissipation function of the wing plate 2.
[0024] Reference Figures 1 to 2 In one embodiment of the present invention, both ends of the clamping plate 3 near the bottom plate 1 are bent to form hook-shaped portions 31, which are hung on the edge of the heat dissipation surface 11 of the bottom plate 1.
[0025] Understandably, both ends of the clamping plate 3 on the side closest to the base plate 1 are bent inward to form a hook-like structure, allowing it to be hung on the edge of the heat dissipation surface 11 of the base plate 1. The hook-like part 31 is directly snapped into the end of the long side 13 of the heat dissipation surface 11 of the base plate 1, forming a sliding and adjustable connection, allowing the clamping plate 3 to move along the base plate 1 and adjust the spacing.
[0026] The hook-shaped design allows the clamping plate 3 to be directly mounted on the base plate 1, reducing the need for additional parts such as screws and clips and simplifying the assembly process. The engagement between the hook-shaped part 31 and the edge of the base plate 1 allows the clamping plate 3 to move along the length of the base plate 1, making it convenient for users to adjust the spacing between the two clamping plates 3 to accommodate heat dissipation objects of different sizes. The hook-shaped structure provides mechanical restraint to prevent the clamping plate 3 from accidentally detaching from the base plate 1 during clamping, ensuring stable clamping.
[0027] Reference Figure 1 In one embodiment of the present invention, the heat dissipation surface 11 of the base plate 1 is detachably connected with stop strips 4 on both sides to prevent the hook-shaped part 31 from sliding out from both sides of the base plate 1.
[0028] Understandably, the stop strip 4 is installed on both sides of the heat dissipation surface 11 of the base plate 1, forming a physical limit to prevent the hook-shaped portion 31 of the clamping plate 3 from sliding out, ensuring that the clamping plate 3 is always kept within the adjustable range. The stop strip 4 uses detachable connections such as clips and screws, making it convenient for users to install or remove, facilitating maintenance or replacement of the clamping plate 3. The stop strip 4 is installed along the short side 14 of the heat dissipation surface 11 of the base plate 1, located at both ends of the sliding path of the hook-shaped portion 31, preventing it from sliding out of the range of the base plate 1.
[0029] Reference Figures 1 to 2 In one embodiment of this utility model, a fixing hole 32 is provided on the surface of the clamping plate 3.
[0030] Understandably, the fixing holes 32 can be used to install screws, bolts, or locating pins, enabling the clamping plate 3 to more securely fix the object being cooled, preventing displacement due to vibration or external force. The fixing holes 32 are typically arranged along the length of the clamping plate 3, and multiple holes are provided to ensure uniform force distribution and avoid localized stress concentration. In addition, they can be designed as single holes, multiple holes, or elongated grooves to accommodate fixing requirements of different sizes.
[0031] This utility model's technical solution employs a base plate 1 with a wing plate 2 structure. The wing plates 2 are arranged equidistantly parallel to the short side 14, and in conjunction with the airflow channel, achieve highly efficient heat dissipation. Two clamping plates 3 are attached to the edge of the base plate 1 via hook-shaped parts 31, and their spacing can be adjusted by sliding along the long side 13 to accommodate electronic components of different sizes. A stop bar 4 prevents the clamping plates 3 from falling off, ensuring safe use. Fixing holes 32 on the surface of the clamping plates 3 support various fixing methods such as screws and positioning pins, providing additional stability. This combined design retains the heat dissipation efficiency of traditional heat sinks while significantly improving versatility and ease of installation through an adjustable clamping structure. The overall solution solves the problems of poor compatibility and inconvenient installation of traditional heat sinks, making it particularly suitable for applications requiring frequent component replacement or high heat dissipation stability, such as industrial equipment, high-power electronic components, and test fixtures. This heat sink offers comprehensive advantages such as flexible installation, safe use, and convenient maintenance while ensuring excellent heat dissipation performance.
