Double pipe heat exchangers are the simplest exchangers used in industries. On one hand, these heat exchangers are cheap for both design and maintenance, making them a good choice for small industries. On the other hand, their low efficiency coupled with the high space occupied in large scales, has led modern industries to use more efficient heat exchangers like shell and tube or plate. H… Thus, heat exchangers function by allowing a fluid of higher temperature ( F1) to interact—either directly or indirectly—with a fluid of a lower temperature ( F2 ), which enables heat to transfer from F1 to F2 to move towards equilibrium. This transfer of heat results in a decrease in temperature for F1 and an increase in … See more The design of a heat exchanger is an exercise in thermodynamics, which is the science that deals with heat energy flow, temperature, and the relationships to other forms of energy.
