We build liquid-cooled plates with Friction Stir Welding (FSW). A spinning tool rubs two aluminum parts together. Heat softens the metal. It mixes and bonds without melting. No cracks. No holes. Just solid join.
Core Features:
Solid-state join: No melt. Zero defects.
Dense channels: Complex flow paths inside.
Lightweight: All-aluminum build.
Strong bond: High strength. Low thermal resistance.
What material combinations are supported for FSW cold plates?
Friction stir welding (FSW) technology has unique advantages in joining a variety of materials, especially in the field of aluminum alloys. Winshare Thermal Alloy specializes in using FSW to manufacture high-performance cold plates, mainly supporting the following material combinations
Aluminum alloy-aluminum alloy FSW cold plate
FSW is an ideal choice for joining aluminum alloys, particularly those in the 6XXX series, such as 6061 and 6063. It overcomes common defects associated with traditional fusion welding, such as hot cracking and strength loss. Aluminum alloy FSW cold plates offer lightweight, high strength, and excellent thermal conductivity, making them widely used in aerospace, electric vehicles, and high-performance electronic devices.
Dissimilar materials FSW potential
FSW technology also has the ability to join certain dissimilar metals, such as aluminum and copper. While not as common in cold plates as joining similar materials, it shows great potential in specific applications, combining the advantages of different metals.
Our team of engineers has deep knowledge of FSW material science and will evaluate and recommend the most appropriate material combination based on your specific application needs and performance goals, ensuring your cold plate achieves the optimal balance between performance, reliability, and cost-effectiveness.
Winshare Thermal, with its deep expertise in precision thermal management, provides AI computing centers with liquid cooling solutions that meet stringent industry standards. For NVIDIA H/B series and high-end domestic AI chips, we offer a complete liquid cooling product chain, from cold plates and CDUs to manifolds, ensuring that GPUs maintain low temperatures even under full load, preventing thermal throttling, and providing a rock-solid cooling base for generative AI and deep learning.
Long-term value from superior performance
FSW cold plates provide excellent heat dissipation efficiency and reliability, effectively reducing the failure rate of electronic equipment due to overheating, extending equipment life, and thus reducing maintenance and replacement costs.
High reliability reduces operational risks
Leak-free, high-strength welds ensure stable operation under harsh conditions, reducing downtime and production losses caused by cold plate failure.
Production efficiency and automation advantages
The FSW process is easy to automate, enabling efficient mass production and reducing the manufacturing cost per unit product.
Material and environmental benefits
FSW eliminates the need for filler materials and flux, reducing material consumption and waste disposal costs. Its clean production process also complies with increasingly stringent environmental regulations, avoiding potential environmental fines and reputational damage.
Reduce total system cost
By providing a more efficient and reliable cooling solution, FSW cold plates may allow for more compact system designs and even reduce the need for other cooling components, thereby optimizing the total cost of the entire system.
