Custom Aluminum Liquid Cooling Plate For EV Battery Pack Thermal Management

Introduction:

Our Custom Aluminum Liquid Cooling Plate for EV Battery Pack Thermal Management is a precision-engineered thermal solution, expertly crafted to address the critical cooling challenges in electric vehicle battery systems. It leverages a robust, multi-stage manufacturing process designed for longevity, structural integrity, and reliable performance.

Engineered from high-grade aluminum sheets, the cooling plate is formed via high-precision stamping to create complex, high-efficiency flow channel patterns. The stamped components are then joined using advanced vacuum brazing technology, ensuring a seamless, leak-proof monolithic structure. We integrate press-riveted threaded inserts for secure mounting, and the surface is finished with a durable epoxy coating for superior corrosion and electrical insulation. Each unit is subjected to comprehensive leak testing and performance validation.

Our custom, stamped, and brazed liquid cooling plates are developed specifically for modern electric mobility, providing a foundational thermal management component. The primary application is:

• Direct Cooling for EV Battery Modules and Packs:​ Designed to be integrated directly with or beneath battery cells to maintain optimal operating temperatures, enhance safety, and extend battery life in electric passenger and commercial vehicles.

• High-Efficiency Stamped Channels:​ The stamping process allows for the mass production of complex, optimized micro-channel or serpentine flow patterns, which maximize heat exchange surface area and ensure uniform thermal distribution across the entire battery pack.
• Robust, Monolithic Brazed Construction:​ Advanced brazing fuses stamped plates into a single, durable piece, eliminating gaskets and providing a permanent, leak-proof seal. This construction withstands thermal cycling and vibration inherent in automotive environments.
• Integrated Mounting and Protection:​ Press-riveted nuts or studs provide reliable, high-strength attachment points for easy battery module assembly. The epoxy coating offers excellent electrical insulation and protects against corrosion from coolants and harsh operating conditions.
• Lightweight and Scalable Design:​ Aluminum construction and efficient material use minimize weight. The stamped and brazed process is highly scalable, enabling cost-effective production for high-volume automotive applications.
• Full Customization for Pack Integration:​ We specialize in tailoring the plate's dimensions, channel layout, inlet/outlet positions, and mounting point locations to your specific battery pack design, ensuring a perfect fit and optimal thermal performance.

Our custom aluminum cooling plates are the ideal thermal foundation for a wide range of electric vehicle battery systems, prioritizing safety, reliability, and manufacturability. We support our clients with end-to-end services, from collaborative thermal design and prototyping to high-volume manufacturing and application engineering.
