Abstract: In one aspect, a heat rejection apparatus is provided including an evaporative heat exchanger and a primary fan operable to direct first ambient air into an air inlet, cause the first ambient air to interact with the evaporative heat exchanger to produce heated air, and discharge the heated air from an air outlet. The heat rejection apparatus includes a plume abatement fan operable to direct second ambient air into contact with the heated air downstream of the evaporative heat exchanger and a controller operably coupled to the primary fan and the plume abatement fan. The controller has a plume abatement mode wherein the controller operates the plume abatement fan to cause the plume abatement fan to direct the second ambient air into contact with the heated air to cool the heated air and abate plume.

Abstract: In one aspect, a heat exchange apparatus is disclosed having a liquid distribution system configured to distribute liquid onto a liquid absorbent material and an airflow generator operable to cause air to flow through the liquid absorbent material and toward an indirect heat exchanger. The heat exchange apparatus includes a controller configured to operate in a dry mode where the controller inhibits the liquid distribution system from distributing liquid onto the liquid absorbent material and a wet mode where the controller causes the liquid distribution system to distribute liquid onto the liquid absorbent material. The controller is further configured to operate at least one of the liquid distribution system and the airflow generator to inhibit drift of liquid from the liquid absorbent material toward the indirect heat exchanger in response to the controller switching from the dry mode to the wet mode.

Abstract: Cooling arrangement and method for cooling of a heat source. The cooling arrangement includes a closed loop, a semi-open loop and at least one fan. The closed loop includes a primary side of a liquid-to-liquid heat exchanger receiving a first cooling fluid heated by the heat source, a first air-to-liquid heat exchanger downstream the primary side, and a first pump returning the first cooling fluid to the heat source. The semi-open loop includes a tank storing a second cooling fluid, a second pump drawing the second cooling fluid from the tank, a secondary side of the liquid-to-liquid heat exchanger receiving the second cooling fluid from the second pump, an evaporating pad downstream said secondary side, and an inlet fluidly connected to a source of the second cooling fluid. The at least one fan causes an air flow through the evaporating pad and through the first air-to-liquid heat exchanger.

Abstract: 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.

Abstract: 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.

Abstract: Spiral finned elliptical tube closed circuit coolers and evaporative refrigerant condensers in which the air flow entering the unit is directed to flow across the tubes in a direction that is parallel to the tube axes and generally perpendicular to the fins produce a completely unexpected gain in capacity of 25% compared to comparable units in which the air flow is directed across/perpendicular to the tube axes.
