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.
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.
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.
Integrated flow channels, no thermal resistance from solder layers, resulting in higher heat exchange efficiency. Excellent temperature uniformity with no local hot spots.
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.
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.
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.
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.
Weld strength reaches over 90% of the base metal. Withstands thermal shock and vehicle-mounted vibration, making it suitable for harsh working conditions.
Free from vacuum furnace size limitations, enabling production of extra-long and large-area water cooling plates while balancing lightweight design and structural strength.
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.
Surface treatments including anodizing and painting are applicable. Offers salt spray resistance and aging resistance for new energy, industrial control, aerospace and other fields.
