Abstract: A heat exchange apparatus which can be used as an evaporative condenser, fluid cooler or wet-air cooler, is provided with a direct evaporative heat exchange section overlying an indirect evaporative heat exchange section. An air entry zone common to both heat exchange sections receives an air stream blown into this zone by at least one fan, thereby pressurizing the plenum such that the air stream is forced to split and enter each section while inside the apparatus.

A countercurrent air flow pattern through the direct section provides a uniformly cooled evaporative liquid for use in the indirect section. The evaporative liquid flow is parallel to the air stream provided in the indirect section.

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.
