Baffles / Spacers

Baffles are plates or vanes installed within heat exchanger shells or tube bundles to direct fluid flow across heat transfer surfaces, creating turbulence and preventing short-circuiting. Spacers are structural elements that maintain precise spacing between tubes, plates, or fins, ensuring uniform flow distribution and mechanical stability under thermal and pressure loads. Together, they optimize heat transfer coefficients, minimize fouling, and extend equipment lifespan in industrial thermal systems.

Baffles work by forcing fluid to flow perpendicularly across tubes or plates, increasing turbulence and convective heat transfer while preventing laminar flow zones. Spacers maintain geometric alignment and prevent vibration-induced damage by securing components at specified intervals. This combination ensures uniform thermal gradients, reduces hotspots, and maximizes surface area utilization through controlled cross-flow patterns.
