Anti-Leak Liquid Cold Plate – Uniform Cooling for Thermal Runaway Prevention

This stamped liquid cold plate is purpose-built for the thermal challenges of next-generation battery systems. Fabricated from 3003 aluminum alloy and sealed through continuous controlled-atmosphere brazing, it delivers exceptional heat dissipation, long-term leak integrity, and structural durability in a lightweight package. The plate’s stamped channel geometry is engineered to maintain cell-to-cell temperature uniformity within ±2°C, a critical threshold for maximizing lithium-ion battery cycle life and safety. Fully compatible with water-glycol coolants and available in custom footprints up to 2,500mm in length, this cooling solution scales from compact EV modules to containerized energy storage racks. Every unit undergoes 100% helium mass spectrometer leak testing before shipment, ensuring zero-defect delivery to North American OEMs and system integrators.

• 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.

Trumony's cold plate is designed to solve supply chain challenges without cutting corners on performance:

· Speed of Stamping: Once the progressive die is set, channels are formed in seconds per plate. This allows us to ship thousands of identical, high-quality plates per month, keeping your assembly line moving.
· Predictable Cost Trajectory: Because stamping is a fast, low-labor process, unit economics improve naturally with volume. We pass this structure through with transparent, tiered pricing.
· Single-Process Validation: We use the exact same stamping tooling and sealing method for prototype samples as for volume production. The thermal performance data you gather from a sample is identical to what every production plate will deliver.
· Scalable Customization: We work with you to finalize channel routing and port placement before committing to the stamping die. Once the die is qualified, scaling up is simply a matter of scheduling production runs.

• The liquid cold plate functions as a compact heat exchanger integrated directly into the battery pack structure.

  Thermal Interface: Battery cells transfer waste heat through a thermal interface material to the cold plate's flat contact surface. The high thermal conductivity of 3003 aluminum rapidly conducts this heat into the channel walls.

  Fluid Dynamics: Coolant enters through the inlet port and is distributed into the stamped channel network. The channel geometry is designed via computational fluid dynamics to induce controlled turbulence at the target flow rate — typically 2–10 L/min per plate. This turbulent flow disrupts the thermal boundary layer that would otherwise insulate the channel walls, dramatically increasing heat transfer efficiency.

  Heat Rejection: As coolant flows through the serpentine or parallel channel matrix, it absorbs thermal energy and exits at an elevated temperature through the outlet port. The heated fluid travels to an external radiator, chiller, or heat exchanger where the thermal energy is dissipated to ambient air before the cooled fluid recirculates.

  Structural Integrity: The continuous brazed bond between the stamped top plate and the flat bottom plate forms a pressure vessel capable of withstanding pump pressures, thermal expansion stresses, and vibration loads encountered in automotive and stationary storage environments. Unlike gasketed or O-ring sealed plates, there are no elastomeric elements to deteriorate or relax over time.
