Abstract (en)
[origin: US2011203782A1] A bladed heat exchanger fin, tube assemblies in which the fin is installed, and methods of using the fin. The bladed fin includes a collar and a radial portion extending radially from an axis of the collar. The radial portion has a base region adjacent the collar and first and second sets of blades that radially extend therefrom. Each blade has a span-wise axis that is transverse to the axis of the collar. Each of the first set of blades is revolved about the span-wise axis thereof so as to have radial edges that are axially spaced from each other, and each of the second set of blades is not revolved about the span-wise axis thereof. At least some of the blades of the first set are between at least some of the blades of the second set.
