Fin Fan Heat Exchanger Sizing

The air cooled heat exchangers also known as fin fan coolers.

Fin fan heat exchanger sizing.

Fin fan cooler is nothing but traditional name of air cooled heat exchanger. An air cooled exchanger is used to cool fluids with ambient air. Fins are used to increase heat transfer area and provide a cooling effect. Air cooled fin fan heat exchanger selection sizing and troubleshooting kolmetz handbook of process equipment design march 2020 project.

In the fin fan coolers the ambient air used as the cooling media to cool. The design of quiet air cooled heat exchangers major noise sources of an air cooled heat exchanger the factors affecting noise from each source and how the source affects the overall noise level of the air cooled heat exchanger are discussed. P perimeter of the fins. Tube configuration used in this guideline.

The air moving device for an air cooled heat exchanger is commonly an axial flow propeller type fan that either forces the air across the bundles forced draft or pulls it across induced draft. H air film convective coefficient a exposed surface area of the fins. However if h a p k is greater than 1 00 the fins will insulate and prevent heat flow. Refer the animated video at the end of the article for proper understanding.

Since fins are used in the cooler it is called as fin fan cooler. Please refer air cooled heat exchanger for all the details. 3 provides the component parts of an air fin fan cooler. Founded in 1923 aerofin is a leading manufacturer of finned tube heat exchanger coils and related heat transfer equipment and accessories such as process gas coolers heaters transformer oil coolers fan coil units face and bypass coils frames for coil removal capabilities airside transitions and drain pans.

1 inch od tube is the most popular diameter and the most common fins are 1 2 inch or 5 8 inch high. Air cooled heat exchanger construction. Fin fan air cooled heat exchangers. To provide redundancy in case a mechanical unit falls and to provide the basic control achievable by running one fan or two a bundle or set of.

Air cooled heat exchanger sizing does preliminary estimation of finned area plot size total fan power and air outlet temperature checalc chemical engineering calculations to assist process plant operation and maintenance engineers. 1 inch od tube 5 8 inch fin height 10 fins per inch and 2 5 inch triangular pitch.
