A heat exchanger is a device designed to efficiently transfer heat between two or more fluids—such as liquids, gases, or a combination thereof—without allowing them to mix. This process is fundamental in various industrial and domestic applications, enabling the heating or cooling of fluids to achieve desired temperatures.
Both fluids enter the exchanger at the same end and move parallel to each other.
Fluids enter from opposite ends, flowing in opposite directions. This arrangement is often more efficient,
Fluids move perpendicular to each other, commonly used in applications like radiators and air conditioning systems.
