Friction Stir Welding (FSW) Cold Plate

I. 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.

II. Premium Performance Selling Points

1. Reliable Sealing · Zero Leakage (Core Advantage)
    
   • 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.
   • Ideal for high-pressure, frequent start-stop, and high-vibration working conditions.
    
2. 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 (pure aluminum / aluminum alloy), no dissimilar metals or filler metals.
   • Excellent corrosion resistance: 500-hour salt spray resistance, supports direct hard anodizing.
    
3. Superior Heat Dissipation · Low Resistance & Uniform Temperature
    
   • Integrated flow channels, no thermal resistance from solder layers, resulting in higher heat exchange efficiency.
   • Flexible flow channel design: large channels, complex layouts, height differences, and extra-long dimensions.
   • Excellent temperature uniformity with no local hot spots.
    
4. Large Size · Ultra-Thin · High Integration
    
   • Not limited by vacuum furnaces; single panel can exceed 2 meters in length.
   • Ultra-thin design (3–8 mm), lightweight yet high-strength.
   • Suitable for power battery trays, high-power lasers, and energy storage cabinets.
    
5. Eco-Friendly · Economical · Stable
    
   • No solder, no flux, no fumes, no waste gas.
   • No chemical residue in flow channels, preventing pump clogging and corrosion.
   • Stable process, high consistency, high yield rate, and long-term maintenance-free operation.
    

III. Comparison with Traditional Processes (One-Sentence Advantages)

• 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.

IV. 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.
