Corrosion Resistant CNC Machined Liquid Cold Plate For EV Battery Packs

Our Corrosion Resistant CNC Machined Liquid Cold Plate is a high-performance thermal management solution, precision-engineered for advanced electric vehicle and energy storage battery systems. It utilizes advanced CNC machining technology, eliminating the need for stamping tooling investment, making it ideal for rapid prototyping, concept validation, and flexible manufacturing.

Crafted from premium-grade aluminum, the core of this plate is precisely sculpted via high-precision multi-axis CNC machining. This process allows for the creation of complex, optimized internal flow channels with exceptional dimensional accuracy. Following machining, the plate undergoes rigorous surface treatments for corrosion resistance, and the assembly is sealed using robust welding or brazing techniques. Each unit undergoes stringent quality verification, including leak and pressure testing, ensuring reliable performance in demanding thermal and pressure conditions.

This CNC machined liquid cooling plate is designed for versatile thermal management applications requiring high flexibility and precision. Its primary applications are:

• Thermal Management for Battery Packs:​ Provides a high-accuracy, customizable cooling solution for both prismatic and cylindrical cell configurations in Electric Vehicle (EV) and Battery Energy Storage System (ESS) applications. It ensures uniform thermal distribution critical for battery performance and longevity.

• Rapid Prototyping & No-Tooling Cost:​ CNC machining enables fast, flexible production of complex channel geometries without the high cost and lead time of stamping molds. This is ideal for concept validation, low-volume production, and designs that require frequent iterations.

• High-Precision, Complex Geometries:​ The CNC process allows for unparalleled design freedom, enabling the creation of sophisticated flow paths, multi-level channels, and precise interface features that are difficult or impossible to achieve with stamping, optimizing thermal performance for specific layouts.

• Superior Corrosion Resistance:​ The machined aluminum surface is treated with durable protective finishes like anodizing or conversion coating, providing excellent resistance to corrosion from coolant and harsh environmental conditions, thereby extending product lifespan.

• Design Flexibility for Diverse Cell Types:​ Easily adaptable to various cell formats. The cooling surface, channel pattern, and mounting features can be precisely machined to match the contact surfaces of both large prismatic cells (e.g., 280Ah) and the interstitial gaps in cylindrical cell arrays (e.g., 21700, 4680).

• Excellent Surface Flatness & Thermal Contact:​ CNC machining ensures superior surface flatness, which is critical for achieving optimal thermal interface contact with battery cells, minimizing thermal resistance and maximizing heat transfer efficiency.

Our CNC machined liquid cooling plates are the perfect solution for R&D projects, pilot production, and applications where design complexity, speed to market, and adaptability are key. We provide expert support from CAD design and thermal simulation to the delivery of functional prototypes and production parts.
