What is heat exchangers?

Heat exchangers are devices used to transfer thermal energy between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. They are widely used in various applications, including heating, ventilation, and air conditioning (HVAC), power generation, refrigeration, chemical processing, transportation, and electronics cooling. Common types include shell and tube, plate, and fin heat exchangers.
