Shell-and-Tube Heat Exchanger Diagram - Engineering Fluid Flow Illustration #1760934 (License: Personal Use)

This black-and-white line drawing depicts a vertical shell-and-tube heat exchanger with multiple internal baffles guiding the shell-side fluid in a zigzag path around the central tube bundle. Arrows indicate inlet and outlet flow directions, demonstrating counter-current heat exchange principles. The design emphasizes thermal efficiency through increased residence time and enhanced convective heat transfer.

Used in mechanical engineering textbooks, HVAC training materials, and industrial process documentation to explain heat transfer fundamentals; targets students, engineers, and technicians seeking conceptual clarity on exchanger operation.
