Heat Exchanger

In systems involving heat transfer, heat exchanger used to condense a gaseous substance into a liquid state through cooling.

U-tube heat exchanger is a form of tube and shell heat exchanger that is used in chemical machinery. The tube box, casing, and tube buddle are the key components of a u-tube heat exchanger. Due to increased no of passes it provides higher surface area for heat transfer.

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. Fluid of the substance to be heated and cooled takes place between alternating sheet allowing heat to transfer through the metal sheet. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.

Finned tube exchangers are known for maximizing heat transfer surface area, by design. Finned tube heat exchangers have tubes with extended outer surface area or fins to enhance the heat transfer rate from the additional area of fins. Finned tubes or tubes with extended outer surface area enhance the heat transfer rate by increasing the effective heat transfer area between the tubes and surrounding fluid. The fluid surrounding finned tubes maybe process fluid or air.
