The principle of thermal exchange was one of the first ones to be used by mankind. Its necessity came from the fact that heat (or lack thereof) is often not found in the appropriate form, substance or place, and has to be transferred where it is needed.
Examples in History of usage of heat exchange can be found in distillation, water heating in Roman Thermae, and of course the preparation of food.
With the Industrial Revolution, the range of applications of heat exchange increased dramatically. Exchangers therefore had to be constantly improved, to make the process faster, safer and more efficient.
Nowadays not only are heat exchangers fundamental in any industrial cycle, but also in everyday life. Examples of common uses are:
Heat exchangers can be divided in two categories according to their operating principle:
Indirect contact exchangers are the most common, as they avoid contamination of the two systems, thus making the process more effective. They can be further categorized in:
Shell-and-tube heat exchangers are the most common, as they can be used in different situations and with different products. Especially in the food industry, they are commonly used for devices like boilers, evaporators, and condensers.
