heat exchangers

Heat exchangers are devices that transfer heat between two or more fluids without mixing them. They are commonly used in industries like heating, cooling, and power generation. Inside, they typically consist of metal surfaces that allow heat to pass from the hot fluid to the cooler one efficiently. For example, in a car radiator, hot engine coolant flows through tubes, transferring heat to the surrounding air. Heat exchangers improve energy efficiency by reclaiming or removing heat, helping systems operate more effectively and saving fuel or energy costs.
