Fin Effectiveness and Efficiency

 Fin Effectiveness:

 1. The thermal conductivity of materials for a given fin dimensions is determined by it.
2. The rate of heat transfer can be calculated from the surface with and without using fins, by using fin effectiveness relationship.
3. It is also used to determine the fin performance.

Fin efficiency:

 1. It is important in determining the geometry of fins.
2. Total heat dissipation  on the surface of fins can calculated by using fin efficiency relation.
3. The actual amount of heat transfer for a given surface temperature is determined.
4. Fin efficiency is used in determining the temperature over the entire length of fin.
