AI Technical Summary

Technical Problem

Traditional hot riveting processes for aluminum bars and separators in large-size CCS modules suffer from problems such as thermal deformation, stress concentration, poor material compatibility, difficulty in controlling process consistency, and difficulty in quality inspection.

Method used

The pin-and-buckle connection structure is adopted. By setting matching grooves and positioning holes on the isolation plate and aluminum bar, and using pins and buckles to achieve mechanical interlocking, the hot riveting equipment and tooling are eliminated, and the elastic buckle part is used to improve the connection stability.

Benefits of technology

It simplifies the manufacturing process of CCS components, reduces production costs, improves component utilization and assembly efficiency, and makes it easier for end customers to assemble them themselves.
