Abstract

An improved finned coil tube assembly (24, 24A, 24B, 24C, 24D) enhances evaporative heat exchanger (26, 26A, 26B, 26C, 26D) performance, and includes tubes (10), preferably serpentine tubes, in the coil assembly. The tubes have a generally elliptical cross-section with external fins (20) formed on an outer surface of the tubes. The fins are spaced substantially 1.5 to substantially 3.5 fins per inch (2.54 cm) along the longitudinal axis (13) of the tubes, extend substantially 23.8% to substantially 36% of the nominal tube outside diameter in height from the tubes outer surface and have a thickness of substantially 0.007 inch (0.018 cm) to substantially 0.020 inch (0.051 cm). The tubes have a center-to-center spacing (DH) generally horizontally and normal to the longitudinal axis of the tubes of substantially 109% to substantially 125% of the nominal tube outside diameter, and a generally vertical center-to-center spacing (Dv) of substantially 100% to about 131 % of the nominal tube outside diameter.
