[0002] The annular copper-aluminum composite heat sink is a heat dissipation device that combines the advantages of copper and aluminum materials. It adopts an annular design so that heat can be evenly distributed on the entire heat dissipation surface to avoid local overheating. This heat sink uses the high thermal conductivity of copper to quickly transfer heat from the heat source to the aluminum heat sink, and then dissipate heat through the large area of ​​the aluminum sheet to achieve efficient heat dissipation. Its composite structure not only ensures the heat dissipation performance, but also makes the heat sink lighter, making it easier to install and use.
