The technology disclosed is a two stage Indirect/Direct Evaporative Cooling (IDEC) cycle whose novel closed loop topology compels system convergence to a stable operating state, wherein air cooling takes place mostly in the indirect stage. The direct stage then serves principally as a water chiller for that process.

The present disclosure relates to a modular heat exchange tower comprising a first module comprising a first basin disposed therein and a second module comprising a second basin disposed therein. The aforementioned modular heat exchange tower may also include heat exchange sections, which are disposed in the first module and the second module. The first module and the second module may be assembled prior to being transported to a job site and installed in the modular heat exchange tower.

An air transfer apparatus being made as a monolithic or an integral structure or enclosure. The monolithic air transfer apparatus or enclosure is made from a non-porous material and is made from any of the manufacturing methods of molding, injection molding, blow molding or extruding. The monolithic air transfer apparatus or enclosure can be any of a cooling tower, a swamp cooler or a cooling Indirect Direct Evaporative Cooler. The monolithic air transfer apparatus has at least one integral cavity manufactured therein and at least one heat exchanger pad can be attached to the monolithic air transfer apparatus or made integral with the monolithic air transfer apparatus.

An air-over evaporative heat exchanger with multi-lobed or “peanut” shaped tubes replacing conventional round or elliptical tubes. The tubes have a narrow horizontal cross section and tall vertical cross section to allow the multiplication of surface area in the same coil volume while maintaining or increasing the open-air passage area. This configuration allows the coil to have an overall external heat transfer coefficient much higher than a conventional coil, while the tube shape allows the use of thinner material, reducing the weight and cost of the heat exchanger.

Improved water management systems which deflect or collect evaporative liquid exiting counterflow heat exchangers and improve airflow distribution are provided. Such heat exchangers include open cooling towers, closed circuit cooling towers, and evaporative condensers. The improved water management systems eliminate water splash out and the noise associated with water splashing. Further, when the fan assemblies are located below the evaporative heat exchanger, the improved water management systems keep the fans dry and prevent freezing in subzero climates.

A heat exchange apparatus is provided with an indirect evaporative heat exchange section. The indirect evaporative heat exchange section includes a series of serpentine tubes, and 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 an indirect evaporative heat exchange section including a series of serpentine tubes with run sections and return bend sections of both normal and increased height. A direct heat exchange section may be provided in the vertical spacing between run sections formed by the increased height return bends.
