Baffles/Support Plates

Baffles/Support Plates are critical internal components in shell-and-tube heat exchangers and calandria vessels. They serve dual functions: baffles create turbulence and direct shell-side fluid flow across tube bundles to enhance heat transfer efficiency, while support plates maintain tube alignment, prevent vibration-induced damage, and ensure structural integrity under thermal and pressure loads. These plates are strategically positioned along the length of the exchanger with precise spacing to optimize thermal performance and mechanical stability.

Baffles work by forcing shell-side fluid to flow perpendicularly across tube bundles in a zigzag pattern, increasing turbulence and heat transfer coefficients. Support plates provide fixed points along the tube length to prevent sagging, vibration, and tube-to-tube contact. Together, they maintain proper tube spacing, distribute mechanical loads, and ensure efficient thermal exchange by maximizing fluid contact with tube surfaces.
