Master the Heat. Eliminate Thermal Runaway
Precision-engineered liquid cooling plates designed to maintain your cell chemistry within an optimal ΔT of ≤ 2°C — even under extreme operating conditions. From micro-channel design to full thermal system integration, we ensure stable, safe, and efficient heat dissipation.
Advanced Thermal Architecture: Engineering the Perfect Flow
We don’t just pump coolant; we choreograph it. From 800V silicon-carbide architectures to extremely dense CTP (Cell-to-Pack) layouts, our customized flow channels ensure unprecedented thermal homogenization.
🔬 Micro-Channel Dynamics
Utilizing precision-extruded or delicately stamped micro-channels to maximize the heat transfer surface area. Crucial for massive localized heat rejection during high C-rate discharging (e.g., Heavy-Duty commercial vehicles).
🔄 Optimized Flow Distribution Strategy
Intelligently balancing pressure drops across parallel and series fluid paths to eliminate thermal bottlenecks. We deliver highly consistent temperature gradients across the entire array, keeping cell-to-cell ΔT (Delta T) ≤ 2°C.
🧩 Cell-Agnostic Thermal Interfaces
Whether dealing with bottom-cooled prismatic cells, side-cooled cylindrical arrays (e.g., 4680), or serpentine ribbon cooling for pouches, our architectures adapt completely to your chosen form factor.
Simulation & Modeling
We don’t rely on trial-and-error manufacturing. Every cold plate is validated in a virtual environment before production, undergoing thousands of simulation iterations to ensure optimal thermal performance.
Measure Twice in the Virtual World. Cut Once in Reality.
Thousands of digital simulations enable a single precise physical realization.
Flow Path Simulation
Digital coolant-flow modeling verifies channel behavior, flow distribution, and hydraulic balance before any plate enters production.
Thermal Uniformity Analysis
By modeling heat generation rates, we optimize internal channel designs to keep pack temperature variation below ΔT ≤ 2°C across the system.
Pressure Drop Optimization
Accurate pressure-flow modeling prevents pump overload while balancing heat-transfer efficiency and overall energy consumption.
Transient Thermal Response
Dynamic simulations of fast charging and high C-rate discharge ensure stable thermal control under short-term peak loads.
Design Iteration Efficiency
Thousands of digital iterations reduce trial-and-error manufacturing and accelerate the path from concept validation to production release.
Production-Ready Validation
Virtual validation supports manufacturable, repeatable cooling plate designs that transition cleanly into real-world production workflows.

⚖️ Extreme Weight-to-Thermal Ratio
Utilizing ultra-thin wall thicknesses (down to 1.0mm) without compromising structural burst pressure. Less cooling hardware weight means more payload capacity for active cell chemistry and greater range.
The Material DNA
Material engineering is a discipline of precision. Our alloy selection strategy reflects deep application-specific expertise, ensuring every solution is built on the right material foundation for its operational environment.
The Right Alloy for the Right Battlefield.
Precision alloy selection tailored to real-world operating conditions.
AL 5052— The Formability & Fatigue Workhorse
With outstanding stampability, elongation, and cold-forming performance, Al 5052 is ideal for thin, lightweight cold plate structures. It's widely used for two-piece stamped-and-joined (welded) liquid cold plates, delivering strong corrosion resistance and reliable fatigue strength--a highly cost-effective choice for high-volume platforms.
AL 6061 — The Sweet Spot of Strength & Machinability
Known for its high yield strength and excellent machinability, Al 6061 is a go-to alloy for structural cold plates. It can handle the combined demands of heavy battery-module loads, mechanical shock, and high-frequency vibration often seen in commercial and off-road duty.
AL 5083 — The Marine-Grade Corrosion Shield
Often regarded as true “marine-grade aluminum,” Al 5083 excels in salt fog, high humidity, and even direct seawater exposure. With top-tier corrosion resistance and strong weldability, it’s an ideal material for marine battery pack baseplates and cold plate assemblies operating in the harshest coastal and offshore environments.
Manufacturing Process Showdown
This is where engineering expertise truly matters. No single process is universally perfect — we guide you toward the optimal engineering trade-off based on your application requirements.
Solid-State vs. Vacuum — Engineering the Perfect Seal
Friction stir welding or vacuum brazing? We engineer the sealing solution, not just the process.
| Criteria | Friction Stir Welding (FSW) ⚙️ | Vacuum Brazing 🔥 |
|---|---|---|
| Working Principle | A high-speed rotating tool generates frictional heat, plasticizing the aluminum and forming a solid-state bond without melting (solid-phase welding). | Components are heated in a vacuum furnace, where filler material melts and flows into joints via capillary action, forming a metallurgical bond upon cooling. |
| Channel Complexity | Best suited for regular geometries and large-scale channels, typically machined via CNC (e.g., milled flow paths in thick plates). | Enables highly complex micro-channel structures and dense flow path designs that are difficult to machine. |
| Structural Strength | Exceptional mechanical strength, with weld joints reaching over 90% of base material strength. Ideal for structural cold plates in heavy-duty applications. | Relatively lower structural strength, better suited for lightweight designs where the cold plate is integrated within battery modules or packs. |
| Size & Scalability | Not limited by furnace size — capable of producing ultra-large cold plates exceeding 2 meters in length. | Constrained by vacuum furnace dimensions, typically suitable for standard automotive or module-level sizes. |
| Our Advantage | Equipped with heavy-duty FSW production lines, enabling both standardized and large-scale customized cold plate welding solutions. | Strong supply chain integration for vacuum brazing, ensuring high consistency and reliable mass production quality. |
Relentless Testing & Validation
For global OEM clients, coolant leakage is a critical failure point — often the root cause of system breakdown. Our QA philosophy is uncompromising: every product is validated under extreme conditions to ensure absolute reliability.
Zero Tolerance for Leakage. Tested Beyond Limits.
Absolute sealing integrity, proven through rigorous, beyond-spec validation systems.
🔬Helium Leak Detection
Vacuum Helium Leak Test, 10⁻⁶ Pa·m³/s
We do not rely on conventional water immersion tests. Every cold plate undergoes 100% vacuum-chamber helium leak detection before shipment, reliably capturing micron-level porosity and pinholes that are invisible to the naked eye—delivering medical-grade hermetic integrity.
💥 Burst & Static Pressure Test
≥1 MPa Overload Testing
The internal flow channels are pressurized well beyond actual operating conditions—typically several times the working pressure (e.g., ≥1 MPa)—to ensure the plate will not bulge or rupture even in fault scenarios such as valve malfunctions or line blockages.
🔄Pressure Pulsation Cycle Test
100,000+ Cycles
We replicate “water hammer” events caused by pump start/stop cycles and abrupt flow transients over the product’s service life. The cold plate is subjected to hundreds of thousands of high/low pressure cycles (e.g., 100,000 cycles) to verify weld durability and prevent fatigue cracking.
❄️🔥Thermal Shock Test
-40°C to +85°C Cycling
Cold plates filled with coolant are rapidly cycled between -40°C and +85°C (e.g., 30-minute dwells at each extreme with rapid transitions) to validate structural and weld stability under aggressive thermal expansion and contraction.
