Abstract:
1. A multi-layered liquid to air heat exchange apparatus through which liquid flows by gravity and is kept in a constant thermodynamic relationship with currents of passing air, comprising: a chamber; a first air opening occupying a surface area on an upper half of the chamber, connecting the chamber with ambient air; a second air opening occupying a surface area on a bottom half of the chamber, connecting the chamber with ambient air; an evaporative media module disposed inside of the chamber occupying the space between first and second air openings, comprising a plurality of evaporative media units assembled vertically in succession and in parallel to one another, wherein the evaporative media unit further comprises a plurality of horizontal evaporative media layers with a top and a bottom surface, the layers are assembled vertically in succession and in parallel to one another; a liquid circulation system embedded in the evaporative media module and configured to deliver steady streams of liquid from a swamp tank at a bottom of the chamber to a top surface of the evaporative media module, and to direct the liquid flowing downward by gravity via a plurality of descending pipes, wherein the descending pipes are vertical and parallel to each other, and are configured to intersect each evaporative media layer in succession; and a blower connected to the first air opening for moving currents of air between the first air opening and the second air opening through the evaporative media module.
