Description

Technical Field

[0001] This utility model relates to the field of carbon fiber heat-conducting plate technology, and in particular to a carbon fiber heat-conducting plate with splicing function. Background Technology

[0002] Carbon fiber heat-conducting plates with splicing function are thermally conductive plates made of carbon fiber as the main raw material and manufactured through a specific process. They can ensure splicing accuracy while ensuring a tight fit at the splice joints, achieving good thermal continuity and effectively expanding the thermal conductivity area. They can meet the heat dissipation requirements of different sizes and shapes and are widely used in fields with diverse requirements for thermal conductivity and size specifications, such as heat dissipation of electronic equipment and thermal management of new energy batteries.

[0003] In real life, most carbon fiber sheets are laid by splicing. However, splicing makes it difficult to fix adjacent carbon fiber sheets together, resulting in poor overall stability. Secondly, when laying them on the top, bottom, left, or right sides, the carbon fiber sheets usually need to be cut to ensure a tight fit. However, splicing cut carbon fiber sheets together does not provide good stability, as they cannot be fixed to adjacent carbon fiber sheets, resulting in poor overall stability.

[0004] An existing patent (publication number: CN220928535U) discloses a carbon fiber plate with improved stability. It includes a first carbon fiber plate and a second carbon fiber plate. The left side of the first carbon fiber plate and the second carbon fiber plate are respectively provided with several first slots. The left side of the first carbon fiber plate and the second carbon fiber plate are respectively provided with several second slots, which intersect with the corresponding first slots. The right side of the first carbon fiber plate and the second carbon fiber plate are respectively provided with several plug-in plates. The right side of the plug-in plates is respectively provided with sliding grooves. Springs are provided in the sliding grooves. The upper part of the springs is connected to sliding rods, and the sliding rods slide in the sliding grooves.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing carbon fiber heat-conducting plates are spliced ​​together using protrusions and grooves. After splicing, loosening and misalignment are prone to occur during use, affecting subsequent normal operation. Furthermore, the protective performance of current carbon fiber heat-conducting plates is limited, making them susceptible to damage from external erosion, which reduces the lifespan of the heat-conducting plate and increases usage costs.

[0006] To address this, a carbon fiber heat-conducting plate with splicing capabilities is proposed. Utility Model Content

[0029] In this embodiment: By setting a first heat-conducting plate 1, which is composed of a multi-layer structure including a carbon fiber base layer 101, a heat-conducting layer 102, a heat-dissipating layer 103, a protective layer 104, and a splicing auxiliary layer 105, the characteristics of each layer material can be fully utilized.

The layers work together to improve the heat dissipation efficiency of the first heat-conducting plate 1 and enhance its protective properties. With its adaptability to splicing, it meets the usage requirements in various complex environments. By setting positioning block 3 and limiting component 2, the positioning block 3 is fixed to the position of the first heat-conducting plate 1, which facilitates the subsequent engagement of the positioning block 3 with the inner wall of the second heat-conducting plate 7 by the first heat-conducting plate 1, thus facilitating the initial positioning and installation. Then, the limiting component 2 is installed on the inner wall of the first heat-conducting plate 1 and the second heat-conducting plate 7, which facilitates the installation and fixation, thus completing the splicing and installation of the first heat-conducting plate 1 and the second heat-conducting plate 7. This improves the reliability and stability of the splicing and effectively avoids problems such as loosening and misalignment at the splicing point.

[0030] Specifically, such as Figure 3 As shown, the limiting component 2 includes a first locking block 201, a connecting plate 202, and a second locking block 203. The side of the first locking block 201 closest to the connecting plate 202 is fixedly connected to the connecting plate 202, and the surface of the first locking block 201 engages with the inner wall of the first heat-conducting plate 1. The side of the second locking block 203 closest to the connecting plate 202 is fixedly connected to the connecting plate 202, and the surface of the second locking block 203 engages with the inner wall of the second heat-conducting plate 7.

Utilizing the excellent thermal conductivity of copper, it can efficiently transfer the heat conducted from the carbon fiber base layer 101 to the heat dissipation layer 103, thereby improving the speed and efficiency of heat conduction. The heat dissipation layer 103 is coated with carbon nanotubes, which can increase the heat dissipation surface area and enhance the heat dissipation effect.

[0037] Specifically, such as Figure 5 As shown, the splicing auxiliary layer 105 is made of thermally conductive silicone and has a thickness of 0.2mm.

[0038] In this embodiment, the splicing auxiliary layer 105 is made of thermally conductive silicone. When in use, the thermally conductive silicone layer is coated on the splicing edge, which can enhance the sealing of the splicing point, prevent external air and impurities from entering from the splicing gap, and further reduce the thermal resistance of the splicing part, so that heat can be transferred smoothly at the splicing point, thereby improving the overall thermal conductivity of the entire large-area heat-conducting plate after splicing.

The coordinated work of these layers improves the heat dissipation efficiency of the first heat-conducting plate 1 and enhances its performance. The first heat-conducting plate 1 offers excellent protection and adaptability to various complex environments, meeting the needs of use in diverse conditions. By setting up positioning blocks 3 and limiting components 2, the positioning blocks 3 are fixed to the position of the first heat-conducting plate 1, facilitating the subsequent engagement of the first heat-conducting plate 1 with the positioning blocks 3 on the inner wall of the second heat-conducting plate 7, thus completing the initial positioning and installation. Then, the limiting components 2 are installed on the inner walls of the first heat-conducting plate 1 and the second heat-conducting plate 7, facilitating installation and fixation. This completes the splicing and installation of the first heat-conducting plate 1 and the second heat-conducting plate 7, improving the reliability and stability of the splicing and effectively avoiding problems such as loosening and misalignment at the splicing points.
