Abstract
A heat exchange apparatus is provided with an indirect evaporative heat exchange section. An evaporative liquid is passed downwardly onto the indirect heat exchange section. The evaporative liquid is collected in a sump and then pumped upwardly to be distributed again across the indirect heat exchange section. An improved heat exchange apparatus is provided with two indirect evaporative heat exchange sections separated by a vertical distance. A direct evaporative heat exchange section may be provided in the vertical spacing between the two indirect evaporative heat exchange sections.
