This 3D animated video explains how a shell and tube heat exchanger works. We look at some of the major components of the heat exchanger and its working principle. A cross section is taken in order to see exactly how the shell and tube heat exchanger works. Shell and tube heat exchangers are the most common type of heat exchanger employed in industrial plants; the second most common is the plate type heat exchanger. The heat exchanger consists of a shell side flowing medium and a tube side flowi
