Heat Exchanger

Heat Exchanger
Heat exchanger are commonly used in a variety of industrial, chemicals, and electronics processes to transfer energy and provide required heating or cooling. Fluid heat transfer systems circulate thermal fluid through process equipment to maintain an even, consistent temperature profile. Heat exchangers come in a large variety of types and sizes. Here are a few of the most common ones.
Coil Hear Exchangers have a long small diameter tube placed concentrically within a larger tube the combined tubes being wound or bent in a coil. One fluid passes through the inner tube and the other fluid passes through the outer tube. This type of heat exchanger is capable of handling high pressures and wide temperature difference.
Shell and tube heat exchangers consist of a bundle of parallel tubes that provide the heat transfer surface separating the two fluid streams. The tube side fluid passes axially through the inside of the tubes. The shell side fluid passes over the outside of the tubes. Baffles external and perpendicular to the tubes direct the flow across the tubes and provide tube support. Tubes sheets seal the ends of the tubes ensuring separation of the two streams. The process fluid is generally places inside the tubes for ease of cleaning or to take advantage of the higher pressure capability inside the tubes.
