What is Heat exchanger?

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

How to Calculate Fin surface area?

Fin surface area calculator uses Surface Area = (pi/2)*Number of Fins*((Fin Diameter^2)-(Outer Diameter^2)) to calculate the Surface Area, Fin surface area formula is defined as a measure of the total surface area of a fin used in heat exchangers, which enhances heat transfer by increasing the area available for heat dissipation. Surface Area is denoted by A_s symbol.

How to calculate Fin surface area using this online calculator? To use this online calculator for Fin surface area, enter Number of Fins (NF), Fin Diameter (FD) & Outer Diameter (d_o) and hit the calculate button. Here is how the Fin surface area calculation can be explained with given input values -> 0.281487 = (pi/2)*8*((0.3^2)-(0.26^2)).

FAQ

What is Fin surface area?

Fin surface area formula is defined as a measure of the total surface area of a fin used in heat exchangers, which enhances heat transfer by increasing the area available for heat dissipation and is represented as A_s = (pi/2)*NF*((FD^2)-(d_o^2)) or Surface Area = (pi/2)*Number of Fins*((Fin Diameter^2)-(Outer Diameter^2)). The Number of Fins is the total count of the fins in length L, Fin diameter is the length from end of one fin to the end of opposite fin on the other side & The Outer Diameter is the diameter of outer edge of circular hollow shaft.

How to calculate Fin surface area?

Fin surface area formula is defined as a measure of the total surface area of a fin used in heat exchangers, which enhances heat transfer by increasing the area available for heat dissipation is calculated using Surface Area = (pi/2)*Number of Fins*((Fin Diameter^2)-(Outer Diameter^2)). To calculate Fin surface area, you need Number of Fins (NF), Fin Diameter (FD) & Outer Diameter (d_o). With our tool, you need to enter the respective value for Number of Fins, Fin Diameter & Outer Diameter and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
