Aluminum Extruded Accordion-Tube-Type Water-Cooling Plate for New Energy Vehicle Batteries

This aluminum-extruded harmonica-tube-style water-cooling plate is manufactured from high-quality aluminum using continuous extrusion and one-piece molding technology, resulting in a weld-free, fully sealed structure. The parallel flow channel design enhances heat dissipation efficiency by 30% compared to traditional serpentine tube cooling solutions and ensures that the temperature difference within the battery pack is maintained within ±1.5°C. Compared to stamping processes, it also reduces weight by 40% and increases compressive strength by 45%, making it ideally suited for the thermal management requirements of 800V high-voltage fast-charging systems.
