Abstract
Description
Technical Field
[0001] This utility model relates to the field of fin installation technology, and in particular to a fin device for high-efficiency heat dissipation. Background Technology
[0002] As the power density of electronic devices continues to increase, heat dissipation has become a key factor limiting the performance and reliability of these devices. Traditional heat dissipation methods, such as natural convection and fan-assisted cooling, are no longer sufficient to meet the heat dissipation requirements of high-power electronic components.
[0003] A novel high-efficiency fin structure for water-cooled heat sinks is proposed in patent CN219679061U. This patent includes fins, guide grooves, and turbulence fins. The fins 1 are toothed heat sink fins, and their guide grooves 2 are toothed grooves. V-shaped turbulence structures are evenly distributed within each guide groove 2 of the fins 1. The spacing between adjacent V-shaped turbulence structures within each guide groove 2 is 2-5 mm. The overflow slots 201 and turbulence fins 3 are triangles or rectangles of the same shape, forming a V-shaped turbulence structure between two triangles or rectangles. The V-shaped turbulence structure is an integral structure formed by die stamping. During processing, the overflow slots 201 are processed using a stamping machine, retaining the bent edges during the stamping process, and then the stamping waste is processed along the bent edges. Bending it to form the turbulence fin 3 is not only convenient to process but also avoids material waste and saves processing costs. The V-shaped turbulence structure consists of an overflow slot 201 and a turbulence block welded and fixed next to the overflow slot 201. The size of the turbulence block is slightly larger than the overflow slot, which can further increase the fluid passage time and increase the heat dissipation area of the fins. The thickness of the turbulence block is 0.3-0.5mm, which can reduce its weight while ensuring heat dissipation efficiency. It can effectively disrupt the boundary layer of the fluid flowing through the water-cooled heat sink while increasing the heat dissipation area of the fins, greatly improving the heat exchange efficiency. Its heat exchange efficiency can be at least twice that of the corresponding fins, meeting greater heat generation requirements. However, the following problems still exist in this patent:
[0004] Existing finned heat sinks typically employ a single connection and fastening structure, such as welding or screw fixing. While these methods can meet heat dissipation requirements in certain application scenarios, they have limitations. For example, the welding process may introduce thermal stress, leading to fin deformation or damage; screw fixing may increase thermal resistance and reduce heat dissipation efficiency. Furthermore, these methods may not be convenient enough for fin maintenance and replacement, and they cannot effectively limit and fasten the fins without damaging them.
[0005] To address the above problems, it is necessary to design a high-efficiency heat dissipation fin device to overcome these issues. Utility Model Content
