Precision-engineered thermal management components designed specifically for lithium-ion battery packs in electric vehicles, energy storage systems, and hybrid electric vehicles. These cooling plates feature complex internal coolant channels machined directly into high-conductivity aluminum plates, providing efficient and uniform heat dissipation across battery cell surfaces to maintain optimal operating temperatures and extend battery cycle life.
Key Features
Precision Internal Channels: CNC machined coolant channels with controlled geometry for optimized flow distribution, achieving uniform battery cell temperature within +/-2°C across the pack
Superior Surface Flatness: Plate flatness within 0.05mm ensures maximum thermal contact area with battery cells, minimizing thermal resistance at the interface
Lightweight Design: Aluminum 6061-T6 construction at approximately one-third the weight of steel, contributing to overall EV weight reduction and extended driving range
Complex Flow Patterns: Serpentine, parallel, multi-zone, and custom channel configurations achievable through multi-axis CNC milling for optimized thermal performance
Battery Coolant Compatible: Anodized surface treatment provides long-term corrosion resistance against glycol-water coolant mixtures commonly used in EV thermal management systems
