The composite structure of pure copper panel and pure aluminum core layer has a thermal conductivity of up to 401 W/(m·K), which can quickly conduct the heat generated during battery operation. It is 60% lighter than pure copper heat dissipation plates, which can reduce the overall vehicle weight of new energy vehicles and improve battery life. The flatness is controlled within ≤0.1mm/m, which can achieve close fitting with the battery module and improve heat dissipation efficiency. It can realize seamless connection with the heat dissipation module through ultrasonic welding, with convenient and reliable installation. It meets RoHS environmental protection standards with no harmful heavy metals, adapting to the environmental protection requirements of new energy vehicles.
The thickness combination is 0.2mm pure copper panel + 1.0mm pure aluminum core layer, with a total thickness of about 1.3mm. The standard size is 1000mm×2000mm, and any size and shape can be customized. The electrical conductivity reaches 98% IACS, which can meet the dual requirements of electrical conductivity and heat dissipation. The unit weight is about 2.8kg/m², 60% lighter than pure copper plates. The surface is treated by anodic oxidation, improving oxidation resistance and wear resistance. The tolerance is controlled within ±0.03mm, adapting to the installation requirements of precision new energy equipment.
It is mainly applied to new energy vehicle power battery tray heat sinks, photovoltaic inverter heat conduction plates, 5G base station heat dissipation modules, industrial electronic equipment heat dissipation panels and other scenarios. Different thickness combinations and shapes can be customized according to customer needs to adapt to different power requirements. It saves 45% of procurement costs compared with pure copper heat dissipation plates, while retaining high thermal conductivity, making it an ideal supporting material for the upgrading of the new energy industry.
