Friction Stir Welding (FSW) Cold Plate is a premium liquid cooling component manufactured using a solid-state welding process. Its core advantages include zero leakage, high strength, long service life, and support for large sizes. It is specially designed for high-reliability, high-pressure applications such as new energy, data centers, and high-power equipment.

Core Process Principle
Friction Stir Welding (FSW)
  • A non-melting solid-state welding process: a rotating stirring tool generates frictional heat to soften the metal (without melting) and forge it into an atomic-level bond.
  • Low-temperature process throughout (< 550°C), eliminating fusion defects, thermal deformation, and material degradation.
Premium Performance Selling Points
Reliable Sealing • Zero Leakage

No porosity, cracks, or shrinkage cavities; 100% dense welds. Burst pressure ≥ 1.5-2 MPa, with stable long-term pressure resistance. Withstands > 10,000 thermal cycles without cracking or leaking.

Strength Near Base Metal • Extra Durable

Joint strength reaches over 90% of the base metal; fatigue and vibration resistance far exceed brazing and fusion welding. Uniform material with excellent corrosion resistance.

Superior Heat Dissipation • Low Resistance

Integrated flow channels, no thermal resistance from solder layers, resulting in higher heat exchange efficiency. Excellent temperature uniformity with no local hot spots.

Large Size • Ultra-Thin • High Integration

Single panel can exceed 2 meters in length. Ultra-thin design (3-8 mm), lightweight yet high-strength. Suitable for power battery trays and high-power applications.

Eco-Friendly • Economical • Stable

No solder, no flux, no fumes, no waste gas. No chemical residue in flow channels. Stable process, high consistency, and long-term maintenance-free operation.

Comparison with Traditional Processes
  • VS Tube-in-Plate: Larger flow channels, lower thermal resistance, no gaps, better temperature uniformity.
  • VS Brazing: No porosity, no solder corrosion, higher strength, longer lifespan, and lower cost for large sizes.
  • VS Fusion Welding / Laser Welding: No deformation, no leakage, better fatigue resistance, and superior thermal cycle durability.
Main Application Scenarios
  • New Energy Vehicles: Battery cold plates, heat dissipation for motor and ECU IGBTs
  • Energy Storage / PV: Energy storage converters, PACK liquid cooling
  • Data Centers / AI: High-power cold plates for GPUs/CPUs
  • Industrial Lasers / Medical: High-power lasers, medical imaging equipment
  • Aerospace: High-reliability cooling for radar and avionics
Key Benefits
FSW Cold Plate: Zero Leakage • High Strength • Long Life • Large Size
Dense, Defect-Free Welds

Adopting solid-state welding technology with no melting, no porosity and no cracks, it eliminates leakage risks at the source and ensures greater stability during long-term high-pressure operation.

Higher Heat Exchange Efficiency

No solder or flux used, removing thermal resistance caused by solder layers. Clean, residue-free inner channel walls achieve more uniform heat transfer, effectively suppressing hot spots.

Excellent Vibration and Fatigue Resistance

Weld strength reaches over 90% of the base metal. Withstands thermal shock and vehicle-mounted vibration, making it suitable for harsh working conditions.

Ultra-Large and Ultra-Thin Designs

Free from vacuum furnace size limitations, enabling production of extra-long and large-area water cooling plates while balancing lightweight design and structural strength.

Flexible Flow Channel Design

Complex flow channels can be customized to adapt to various heat source layouts such as power batteries, energy storage systems, high-power IGBTs and GPUs.

Corrosion Resistant Surface Treatment

Surface treatments including anodizing and painting are applicable. Offers salt spray resistance and aging resistance for new energy, industrial control, aerospace and other fields.
