High-Performance Thermal Management Component Stamped Brazed Battery Liquid Cooling Plate

Our Liquid Cooling Plates (LCPs) are specifically engineered for EV battery packs and energy storage systems, available in two mainstream configurations: Stamped Brazed and Serpentine Tube. The Stamped Brazed type features complex flow channel design and exceptional temperature uniformity (∆T ≤ 2°C), making it the ideal choice for highly integrated CTP/CTC architectures. The Serpentine Tube type offers lightweight construction and low flow resistance, precisely tailored for cylindrical cell modules. Every unit undergoes rigorous helium leak testing at ≤1×10⁻⁷ Pa·m³/s, ensuring zero-leakage performance under extreme operating conditions and full compliance with stringent North American UL/SAE safety standards

• 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 continuous brazed cold plate operates as a high-efficiency counterflow heat exchanger integrated directly into the heat source. Here is the thermal pathway in sequence:

  1. Thermal Collection: Heat generated by the semiconductor junction or battery cell surface migrates through a thin, high-conductivity thermal interface material (TIM) into the cold plate's precision-ground top face.
  2. Spreading & Conduction: The solid aluminum lid conducts heat downward into the internal fin field, where the continuous brazed joints ensure no thermal constriction occurs at the bond interface.
  3. Fluid-Side Convection: Coolant entering the inlet manifold is evenly distributed across hundreds of micro-channels or pin arrays. As the fluid velocity increases within these constricted pathways, the flow transitions from laminar to turbulent — dramatically increasing the convective heat transfer coefficient.
  4. Heat Rejection Loop: The heated coolant exits through the outlet manifold and travels to a remote Cooling Distribution Unit (CDU), where a liquid-to-air or liquid-to-liquid heat exchanger rejects the thermal energy to the ambient environment.
  5. Closed-Loop Return: Cooled fluid returns to the pump and reservoir, completing the circuit. The entire system operates under slight positive pressure to prevent air ingestion and cavitation.
