increases temperature gradient so as to enhance heat transfer  

increase turbulence inflow for enhancing heat transfer 

increase  surface area to promote the rate of heat transfer

decrease the pressure drop of the fluid

reduce the total weight 

accommodate more number of fins 

increase the width for the same profile area 

improve the flow of coolant around the fin
