Section 5.4 Shell and Tube Heat Exchanger CorrectedShell-and-tube heat exchangers can have multiple passes, such as 1-1, 1-2, 1-4, 1-6, and 1-8 exchangers, where the first number denotes the number of the shells and the second number denotes the number of passes. An odd number of tube passes is seldom used except the 1-1 exchanger. A 1-2 shell-and-tube heat exchanger is illustrated in Figure 5.19.
The convention in shell-and-tube heat exchangers is as follows:T 1:inlet temperature of the shell-side (or hot) fluid . T 2:exit temperature of the shell-side (or hot) fluid t 1:inlet temperature of the tube-side (or cold) fluid . t 2:exit temperature of the tube-side (or cold) fluid Thus, (1 Shell-and-Tube Heat Exchangers McMaster-CarrAlso known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. Theyre commonly used in refrigeration and engine cooling systems. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.
