Tube and Shell Heat Exchanger

Definition and Basic Concepts

The Tube and Shell Heat Exchanger is a widely used industrial heat transfer device. It mainly consists of a shell, tube bundle, tube sheets, baffles, and nozzles. The cylindrical shell contains tube bundles fixed at both ends to tube sheets, which are welded or expanded to the shell. Baffles support and guide fluid flow within the tube bundle to enhance heat transfer efficiency. This exchanger facilitates heat transfer and temperature regulation through thermal exchange between fluids inside and outside the tubes.
