Energy storage cold plate joint welding

What are cold plates for electronic cooling?

Cold plates for electronic cooling feature a casing with a cooling liquid channel and a cover. Ensuring watertightness, thermal efficiency and durability at a cost-effective price is vital. FSW welding addresses these requirements. Solid-state FSW process eradicates porosity, ensuring a leak-proof seal in both aluminum and copper.

How to ensure optimal fsw welding results for your cold plate?

To guarantee optimal FSW welding results for your cold plate, several critical factors must be evaluated. Each of these contributes to the overall quality, durability and performance of the assembled product: Dimensions of the cover: The thickness of the cover is a pivotal aspect, with a range from a minimum of 1 mm up to a maximum of 12 mm.

What factors affect cold plate technology?

When it comes to cold plate assembly, cost and safety are two crucial factors that often dictate the choice of technology. Friction Stir Welding and Vacuum Brazing represent two different paradigms in both aspects. Cost Impact on Cold Plate Technologies By using an FSW welding head for machining centers, you can reduce your costs by up to 10 times:

What are the advantages of friction stir welding over copper tubing?

When evaluating methods for joining cold plates, the advantages of friction stir welding technology over the copper tubing technique become evident. Firstly, the copper tube method limits cooling performance, making it difficult to achieve high channel density.

What influences the quality of a weld joint?

As stated by Peng (2022) , the formation of intermetallic and the difference in thermal properties alongside the process parameters such as welding speed, current, and voltage weld quality largely influences the quality of the weld joint.

How long does it take to weld a plate?

Fast manufacturing for large and small plates: approximately 10 minutes for welding large plates and about 1 minute for smaller plates, with the ability to weld up to 40 plates on the same table. Low energy consumption: similar to standard machining process. Total costs of vacuum brazing operations are steep:
