Anodized Surface Aluminum Liquid Cold Plate For Electric Vehicle Battery Thermal Control

Introduction:

Our Anodized Surface Aluminum Liquid Cold Plate is a high-reliability thermal management solution specifically engineered for electric vehicle battery systems. It leverages a mature manufacturing process combining precision stamping and advanced anodizing to deliver robust, corrosion-resistant cooling for high-volume production.

Manufactured from premium-grade aluminum, the core of this cold plate is formed using our established precision stamping tooling, which efficiently creates high-performance micro-channel flow paths. The stamped components are then assembled and sealed. The entire unit undergoes a specialized anodizing surface treatment, creating a hard, durable, and non-conductive oxide layer. This process eliminates the need for new customer tooling investment, making it ideal for cost-effective, large-scale manufacturing. Each plate is validated for leak-tight integrity and functional performance.

This anodized cold plate is designed for efficient, large-scale thermal management in modern electric mobility. Its primary application is:

• Thermal Control for Prismatic Cell EV Battery Packs: Specifically optimized for cooling large-format prismatic lithium-ion cells. The design ensures uniform heat dissipation across the cell's broad surface, which is critical for maintaining performance, safety, and cycle life in electric vehicles.

• Corrosion & Rust Proof Surface: The anodized surface forms a hard, integral aluminum oxide layer that provides excellent resistance to corrosion from coolants and environmental exposure. It also acts as a superior electrical insulator, enhancing pack safety.

• Cost-Effective for High Volume: Utilizing existing, proven stamping tooling allows for rapid ramp-up and highly cost-efficient mass production, eliminating upfront mold costs and reducing unit price for large orders.

• Durable and Scratch-Resistant: The anodized coating is significantly harder than the base aluminum, offering excellent resistance to abrasion and wear during handling and battery pack assembly, ensuring long-term surface integrity.

• Efficient Thermal Performance: The precision-stamped micro-channels are optimized for coolant flow and heat transfer, effectively managing the thermal load generated by high-capacity prismatic cells during operation and fast charging.

• Standardized Yet Adaptable Design: Based on proven tooling, the design offers reliability and consistency. We can customize certain aspects like overall dimensions (within tooling limits), port configurations, and the anodizing color/thickness to meet specific application needs.

Our anodized aluminum liquid cold plates are the optimal thermal solution for volume production of electric vehicle battery packs using prismatic cells, where cost, manufacturing scalability, corrosion resistance, and electrical insulation are key requirements. We provide full support from application engineering to just-in-time delivery for production lines.
