Heat Exchangers

Heat exchangers are devices used to change the temperature, pressure or composition of a fluid or gas. It is part of a closed system, often used in industrial processes and for heat transfer, and can be used for a variety of purposes such as temperature changes, heat recovery, or cooling or heating liquids.

Heat exchangers operate in an area where two different fluids (usually liquid or gas) come into contact with each other. One fluid transfers heat to another and thus the temperature difference is eliminated. Thus, as the temperature of one fluid increases, the temperature of the other fluid decreases.

Heat exchangers are used in industrial processes, power plants, HVAC systems and many other applications. For example, in a home's heating systems, a heat exchanger helps transfer heat from one room to another or hot water to cold water.

Heat exchangers can be of different types such as tubular heat exchangers, plate heat exchangers or shell-tube heat exchangers. Tube heat exchangers use a bundle of tubes through which fluids pass between two tubes, while plate heat exchangers use a series of plates through which fluids pass through spaces between thin metal plates. Shell-tube heat exchangers, on the other hand, use a tube bundle enclosed in a large shell with a tube bundle inside.

Heat exchangers are widely used in industrial processes to increase energy efficiency, reduce costs and optimize processes. For example, by using a heat exchanger, you can use hot water used in a process to heat cold water or cool hot gas. This saves energy and improves process efficiency.
