Vol.007 - Cold Plate Performance Is Not Just About Flow Paths: The Joining Process Matters
Precision Joining: Choosing Between Friction Stir Welding and Vacuum Brazing 1. Introduction: How Joining Processes Affect Liquid Cooling Performance and Reliability This issue takes a closer look at how the joining process determines the final quality of a product. In liquid cooling systems, the air-tightness and liquid-tightness of a cold plate are core indicators of long-term system stability, and weld quality directly affects heat transfer efficiency and product lifetime. Common joining methods for liquid cold plates include: · Friction Stir Welding (FSW) · Vacuum Brazing · TIG/MIG Welding · Diffusion Bonding · Laser Welding This article focuses on the two most widely used solutions in high-performance server cold plates today: Friction Stir Welding (FSW) and Vacuum Brazing. I...
