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, The Fin surface area formula is defined as the area on the surface required for the fin for effective heat transfer. Surface Area is denoted by As 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 (do) 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)).
