Heat Exchangers

Quick answer A shell‑and‑tube heat exchanger uses a bundle of tubes inside a cylindrical shell so two fluids exchange heat across the tube walls—one flows through the tubes, the other around them in the shell. Key elements include the tube bundle (tubes, tube sheets, baffles), the shell, and front/rear heads; common tube materials range from […]

Quick answer Shell‑and‑tube exchangers are recuperative designs where two fluids stay separate and trade heat across tube walls; systems can run co‑current (parallel) flow, while other industry heat‑exchanger classes include direct‑contact and regenerative. In practice, shell‑and‑tube units are built as fixed tube sheet (clean, economical), U‑tube (handles thermal growth), or floating head (best for dirty
