3003+4343 brazing aluminum plate for electric vehicle battery cooling plates
As the energy density and power density of new energy power batteries increase, the charge and discharge rate of the battery increases, and the calorific value of the battery also increases. The heat dissipation of the battery becomes a problem. Due to its better heat dissipation effect, the water-cooled plate has gradually become the mainstream heat dissipation method for batteries. Electric vehicle battery cooling plates are an important part of the thermal management system of electric vehicles and are often used in load-bearing, corrosion-resistant environments. The electric vehicle battery cooling plate is generally made of aluminum brazing composite material. In order to ensure its stamping and tensile requirements, the material used is required to have good tensile capacity.
3003 aluminum plate has good formability, good corrosion resistance and weldability. Mingtai Aluminum has developed a production process for brazed pre-composite materials and is currently able to custom produce aluminum coils for battery cooling plates. Product alloy grade: 3003 aluminum plate coil, 3003mod aluminum plate coil; composite aluminum coil: 3003+4045 brazing aluminum plate coil, 3003mod+4343 brazing aluminum plate coil. Mingtai Aluminum provides aluminum sheets in various thickness states, and the product size can be customized on demand.
