Stamped Brazed & Serpentine Tube Liquid Cooling Plate for Prismatic EV Battery

Our Liquid Cooling Plates (LCPs) are precision-engineered thermal management components designed for electric vehicle battery packs and stationary energy storage systems. We offer two proven technologies: Stamped Brazed plates with intricate flow networks for superior heat distribution, and Serpentine Tube designs optimized for cylindrical cell geometries. Both configurations deliver exceptional cooling efficiency, structural durability, and leak-tight integrity. With full customization capabilities and rapid CFD simulation support, we provide North American OEMs and Tier 1 suppliers with reliable, production-ready thermal solutions that enhance battery safety, extend cycle life, and maximize driving range in all climates.

• Stamped Channels: Complex flow paths formed in seconds at low cost, ideal for high-volume scaling.
• Leak-Proof Construction: Solid-state sealed for permanent, maintenance-free operation with no internal contaminants.
• Custom Configurable: Size, port locations, mounting bosses, and surface treatments can be tailored to your module layout.
• Fast Sample Turnaround: Functional prototypes delivered in weeks, using the same production-ready process.
• Certification Support: Full documentation and material traceability to assist with UL 1973 and UL 9540A compliance.

For a detailed recommendation, please provide:

• Cell type, dimensions, and quantity per module

• Maximum heat generation per cell (W/cell)

• Nominal coolant flow rate and inlet temperature

• Available pack space (3D model preferred)

• Target operating temperature range

Our engineering team provides complementary CFD thermal simulations within 48 hours to validate plate sizing and channel configuration before tooling commitment.

✔ Stamped Brazed – Superior Thermal Uniformity: Utilizing high-grade aluminum alloys (3003/6063) with precision vacuum brazing, our stamped plates feature multi-pass flow networks that ensure coolant distribution is perfectly matched to cell heat maps. Achieve surface temperature differentials as low as ≤2°C across the entire pack, minimizing cell imbalance and maximizing usable capacity. The brazed construction provides excellent structural rigidity, making these plates ideal for load-bearing CTP applications.

✔ Serpentine Tube – Lightweight Cylindrical Cell Optimization: Purpose-built for cylindrical formats (18650, 2170, 4680), our serpentine tubes are manufactured using precision CNC bending and orbital welding. The sinusoidal routing maximizes surface contact with each cell row, while thermally conductive gap fillers bridge the line-contact interface, reducing thermal resistance by up to 40%. With pressure drops below 18kPa, these tubes minimize parasitic pump energy losses.

✔ Zero-Compromise Leakage Protection: Every plate undergoes 100% helium leak detection with sensitivity down to 1×10⁻⁷ Pa·m³/s – 10x tighter than typical industry requirements. Our proprietary surface passivation process, combined with coolant additive compatibility testing, ensures long-term resistance to pitting, crevice corrosion, and stress corrosion cracking, even with aggressive glycol formulations.

✔ Production-Ready Customization: From prototyping to high-volume production (capable of 500,000+ units annually), we support your entire product lifecycle. Our in-house tooling, stamping, brazing, welding, and assembly capabilities ensure complete process control and faster time-to-market.
