Shell & Tube Type Heat Exchanger

Definition and Basic Structure

The Shell & Tube Type Heat Exchanger is a widely used industrial heat exchange device. Its basic structure consists of two main components: the shell and the tube bundle. The cylindrical shell contains multiple parallel tubes (the tube bundle). This design allows two fluids at different temperatures to flow in isolated spaces while transferring heat between them. One fluid (typically liquid or gas) flows through the tubes (tube-side fluid), while the other flows between the shell and tubes (shell-side fluid).
