ABSTRACT:
A closed circuit evaporative fluid cooler/evaporative condenser utilizing a cross flow water-air fluid flow relationship is provided. An evaporative liquid recirculating system includes a liquid distribution spray assembly mounted above a bundle of fill sheets. A closed circuit fluid cooling/condensing heat exchanger is supported below the bundle of fill sheets. Each heat exchanger comprises a plurality of parallel coil circuits or modules, wherein the inlet of each coil circuit is at a higher elevation adjacent the air outlet side of the heat exchanger, and the fluid outlet manifold of each coil circuit is at the lowest elevation adjacent the air inlet side of the heat exchanger. This arrangement assures the coolest liquid falling from the fill sheet assembly contacts the coil assembly containing the coolest fluid and that the coolest air entering the air inlet contacts the coil assembly portion containing the coolest fluid. Each coil assembly comprises a plurality of parallel individual coil circuits each having downwardly sloped straight runs connected by return bends to assure the complete pass through and drainage of the fluid therein.
