Distribution Baffle

A distribution baffle is a precisely engineered plate or barrier installed within tube sheets or headers of heat exchangers, boilers, or condensers. Its primary function is to control and optimize fluid flow patterns by redirecting incoming fluids to achieve even distribution across all tubes. This prevents channeling, reduces thermal stress, and maximizes heat transfer efficiency by ensuring each tube receives consistent flow rates and temperatures.

The distribution baffle operates on fluid dynamics principles, using its geometric design to create controlled pressure drops and flow paths. As fluid enters the header, the baffle redirects it through specific openings or channels, breaking up high-velocity streams and distributing flow evenly across the tube sheet. This prevents preferential flow through certain tubes while others receive inadequate flow, ensuring balanced thermal performance and mechanical stability.
