ABSTRACT:
A fluid cooler having contiguous air cooled and evaporative portions and having a heat exchanger common to both portions. The heat exchanger employs a series of straight tubes which traverse both the air-cooled and the evaporative portions. Separate fans are provided for the air-cooled and for the evaporative portions. The segments of the straight tube laying within the air-cooled portion are finned. The segments of straight tubes laying within the evaporative portion are partially finned and extend further downwards as a sub-cooling section of the evaporative coil portion, thereby providing means for cooling the fluid to a temperature lower than ambient dry-bulb temperature.
