Inner Diameter - (Measured in Meter) - The Inner Diameter is the diameter of inner circle of circular hollow shaft.
Fin Efficiency - Fin Efficiency is defined as the ratio of heat dissipation by the fin to the heat dissipation takes place if the whole surface area of the fin is at the base temperature.
Surface Area - (Measured in Square Meter) - Surface Area of a three-dimensional shape is the sum of all of the surface areas of each of the sides.
Bare Area - (Measured in Square Meter) - Bare area of fin over the fin leaving fin base.
Effective convection coefficient on outside - (Measured in Watt per Square Meter per Kelvin) - Effective convection coefficient on outside as the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat.
Convection coefficient based on inside area - (Measured in Watt per Square Meter per Kelvin) - Convection coefficient based on inside area is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat.

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.
