Which radiator is better?
with my basic knowledge in heat transfer id assume a larger aluminum piece. Q(the heat transfered) = hADeltaT h is the convective heat transfer coefficient, and delta T is the difference in temp between the surface of aluminum and air where A is the surface area of heat transfer on the air side of the heatsink…more surface area = more heat transferred…in theory.
