A plate-fin is a variety of custom shell and tube heat exchangers design that utilizes a plated and finned chamber in order to move heat in between fluids. It is often classified as a compact exchanger of heat to emphasize its relatively high heat conversion surface area to quantity ratio. The plate-fin is widely used in several industries, like the aerospace business for its compact size and light-weight properties, as well as in cryogenics exactly where its ability to facilitate warmth transfer with little temperature differences is required.A plate-fin exchanger consists of layers of corrugated sheets divided via flat metal dishes, usually aluminum, to establish a number of finned chambers.Separate cold and hot fluid streams circulation through alternating levels of the exchanger and are generally enclosed in the sides through bars at the sides. Heat is moved from one stream with the fin interface towards the separator plate and with the next set of fins to the adjacent fluid.The actual fins also serve to boost the structural integrity from the heat exchanger and allow this to withstand high demands while providing a long surface area for the exchange of heat.

FINNED TUBE EXCHANGER
Finned Tube Heat Exchangers consist of a shell & finned tubes assembly. Fins are
used to increase the effective surface area of heat exchanger tubing. Finned tubes
are used when the heat transfer coefficient on the outside of the tubes is
appreciably lower than that on the inside; as in heat transfer from a liquid to a gas,
vapor to a gas, such as steam to air heat exchanger, thermic fluid to air heat
exchanger. When an extended surface is needed on only one fluid side (such asin a
gas to liquid exchanger) or when the operating pressure needs to be contained on
one fluid side, a finned tube heat exchanger may be selected.
