The fluids can be of different types, such as liquids, gases, or even solids. This energy transfer is usually achieved by conduction, convection, or radiation. Heat exchangers are widely used in many industries and applications, including heating, ventilation, air conditioning, power plants, chemical processes, and refrigeration systems. They are designed to efficiently transfer heat while minimizing heat loss and pressure drop. There are several types of heat exchangers, including shell and tube, plate, and finned tube heat exchangers. Each type has its advantages and disadvantages, depending on the specific requirements of the application. Heat exchangers play a crucial role in improving energy efficiency and reducing environmental impact, as they enable the recovery of waste heat and the transfer of thermal energy from one process stream to another.
