The double-tube heat exchanger described in Chap. 5 is limited to applications in which the heat flux Q and the fluids flow rates are small. If higher flow rates have to be processed, it would be necessary to install several units in parallel, and the resulting design would not be compact, and maintenance would be difficult.
To avoid these inconveniences, the shell-and-tube heat exchanger is normally used. The basic idea consists of installing several internal tubes into another tube of much bigger diameter, designated as the shell.
This construction is illustrated in Fig. 6-1, and Table 6-1 provides the nomenclature for the figures.
