What factors or parameters in the fin dictates its efficiency. if you want to improve fin efficiency, clearly describe how you will achieve it.

Explanation:

Fin efficiency can be define as the ratio of actual flow of to the maximum flow of heat through fins.

So in short form we can say that

Lets take infinite long fin to understand the all factors which affect the fin efficiency

So efficiency of long fin given as

And we know that

So from we can say that for better efficiency the heat transfer coefficient will be low and conductivity for fin should be high.
