ABSTRACT:
An air-cooled tower for cooling of fluid wherein a vortex is established within a vertically standing cylinder.
Air entering through the upper portion of the cylinder is directed tangentially and downwardly, establishing a downwardly flowing vortex which is reversed at the bottom forming a smaller diameter intense upwardly flowing vortex. Additional air is induced through the center of the cylinder at the bottom. Heat exchange between the fluid to be cooled and the air is through indirect heat exchange surface or direct injection of the fluid. Evaporative cooling is accelerated due to the turbulent conditions, and the centrifugal action reduces the water carryover in the airstream exiting from the top of the cylinder. A turbine-fan combination centrally located at the bottom of the cylinder permits supplementing the airflow under low-wind conditions and extracting energy from the induced airflow under high wind conditions.
