  • Patent number: 9587842
    Abstract: For minimizing the effect of wind on a heat exchanger system having a plurality of finned tube arrays and a plurality of fans, a method includes providing a wind louver below one of the fans. The wind louver is arranged to divert wind flowing in an approximately horizontal direction below the one of the plurality of fans to instead flow in a direction that is more vertically upward as compared to the approximately horizontal direction. Readings of a heat exchanger outlet temperature, ambient temperature, wind, and inlet air pressure are collected and recorded, and compared to previous readings. The louver height is changed if the readings have changed.

  • Patent number: 9360258
    Abstract: An air cooled, finned heat exchanger tube includes a metallic tube through which fluid to be cooled is flowable. The tube has an outer surface on which axially spaced axial indentations are formed over its circumference, and a plurality of axially spaced fins each of which has a main element formed with heat transfer promoting patterns and a base angled with respect to said main element. The base is frictionally and irremovably secured within a corresponding indentation so that said tube outer surface is completely covered.
