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.

An adaptive condensing device for a dual-loop heat pipe air conditioner is presented. The adaptive condenser device may include a condenser body. A first electric shutter and a compressor condensing heat exchanger are disposed on one side of the condenser body, a second electric shutter and a heat pipe condensing heat exchange micro-channel are disposed on the other side of the condenser body, and a fan is disposed on the top of the condenser body. This may give rise to the compressor and the heat pipe being able to perform refrigeration under the working condition, and there may be no need to configure two condensers, thereby reducing installation space, facilitating installation and maintenance, and reducing costs.

A tube bundle for an evaporative refrigerant condenser having a plurality of straight single pass tubes extending between a refrigerant inlet header and a refrigerant outlet header, said tubes having a cross-sectional shape in the form of an ellipse having a major axis and a minor axis, wherein said major axis is longer than said minor axis by a factor of 3 to 7, wherein the amount of required refrigerant charge for a particular heat exchange capacity is substantially and unexpectedly reduced resulting in a substantial and unexpected increase in efficiency.

An apparatus is provided. The apparatus includes a heat exchanger providing heat transfer between a first medium and a second medium. The apparatus also includes a movable aperture integrated onto a face of the heat exchanger and regulating a flow of the first medium based on a position of the movable aperture. The apparatus further includes an actuator controlling the position of the movable aperture.

A cooling tower is provided having a heat exchange section, and a fan for moving air through the heat exchange section. A water distribution assembly provides water onto and through the heat exchange section. An air inlet section is provided through which air is drawn into the cooling tower and the heat exchange section. The air inlet section has outside edges and corners. A wall assembly is provided in the air inlet section, with the wall assembly extending from the corners of the air inlet section inwardly. The water passing through the heat exchange section enters the air inlet section, and exits to a sump beneath the air inlet section. The air inlet section is comprised of a structure having outside edges and corners, and the wall assembly is comprised of a plurality of wall panel sections. Each wall panel section has an outer edge at a corner of the air inlet section, and each wall panel section extends inwardly from the corner of the air inlet section.
