Friction Stir Welding Manufacturing Process
Customized Cooling Module with FSW Technology | Evercool
What is Friction Stir Welding (FSW)?
Friction Stir Welding (FSW) is a solid-state joining technique that produces high-strength, seamless joints without melting the materials. By generating frictional heat through a rotating tool, the material softens and plastically flows under pressure, resulting in a dense, leak-proof, and robust thermal connection.
Unlock High-Efficiency Cooling for Power-Dense Applications
High-performance servers, AI computing platforms, and industrial-grade power modules all face the challenge of high heat density and large thermal loads. Evercool leverages Friction Stir Welding (FSW) technology to integrate customized liquid cold plates with aluminum heat sinks, forming a unified fan/liquid hybrid cooling system that effectively resolves thermal bottlenecks.
This advanced thermal module solution is ideal for high-power electronics, server CPUs/GPUs, water-cooled inverters, IGBT power modules, laser systems, and more.
Key Benefits:
- No soldering materials required, eliminating leak and void risks
- Strong metallurgical bond with low thermal resistance
- Ideal for aluminum-based heat spreaders and cold plates
- Reduces tooling and production cost for large thermal modules
