The main advantages of shovel tooth heat sink technology are reflected in structural design innovation, material performance optimization, and process efficiency improvement. Its shovel tooth technology integrates the substrate (aluminum/copper) into ultra-thin fins through high-precision cutting, breaking the 20 fold limit of traditional extrusion technology in terms of tooth height; The heat dissipation area per unit volume increases by more than 30%, and the fins have no contact with the substrate, avoiding thermal resistance loss and achieving 100% release of thermal conductivity; By using high-purity aluminum or copper aluminum composite materials, the corrosion resistance is significantly improved while maintaining lightweight. Applied in multiple fields, its ultra-thin high-density tooth structure can quickly export heat generated by high-power components such as 5G base station chips, graphics cards, and GPUs; The shovel tooth technology supports the processing of copper aluminum composite materials and achieves efficient heat exchange through microchannel water cooling head design. In new energy and energy storage systems, their lightweight characteristics are utilized to provide a reliable heat dissipation solution for battery pack thermal management systems with large dimensions and no welding points.
