Abstract: A tube-and-fin assembly comprises a generally elliptical, cylindrical, elongated aluminum tube and a plurality of aluminum fins. Each fin extends outward from a side of the tube body to an apex. The aluminum assembly has a ratio of fin height to fin density (Mokire ratio) of between about 0.3200 and about 0.4125. The fin height is about 6.4 mm to about 6.6 mm and the fin density is about 16 to 20 fins per inch (FPI). The fins may be part of a corrugated sheet affixed to either side of the tube. The aluminum assembly achieves heat transfer performance similar to that of copper assemblies while maintaining a similar space claim.
