Variable performance vaneaxial fan with high efficiency

Номер: US20120128494A1
Автор: Bryan M. Pelley, Chris D. Hemmelgarn, Jennifer M. Fries, Joseph H. Althaus
Принадлежит: Cornerstone Research Group Inc

The design of a high efficiency, variable performance vaneaxial fan, requires the utilization of typical fan and single stage compressor design methodologies. To be able to replace multiple fans, the variable vaneaxial fan design must be capable of operation at several different flow rates and total pressures. These operation points can be met by varying motor revolutions per minute (RPM) or geometric parameters such as the hub diameter, tip diameter, as well as blade geometry including number of blades, pitch, spacing, and length. An ideal design with variable performance can replace a family of current fan designs by providing the capability for efficient operation over a range of flow rates and total pressures. This level of variability would not only allow the fan to respond to changing environmental conditions but also to be fit into systems with different characteristics.

An evaporative cooling apparatus includes a liquid reservoir and a pump coupled to the liquid reservoir. The pump includes a pressure output that applies a static pressure against the liquid stored in the liquid reservoir. The applied pressure forces liquid through a liquid supply line to a nozzle unit, and the liquid is ejected into a stream of forced air from a fan for evaporative cooling applications. The pressure output is also in fluid communication with the nozzle unit via a gas supply line extending between the pressure output and the nozzle unit for delivering gas into the nozzle unit. The gas delivered to the nozzle unit interacts with the liquid inside the nozzle unit to generate the atomized spray of liquid droplets.

A fan design method and fan structure is described, enabling independent control of the volume of airflow and the amount of noise produced. The noise produced is a close approximation to a pleasing red noise spectrum, and is generated solely by the interaction of the rotating fan blades with a petal assembly or a fan enclosure in several embodiments. A petal assembly may be positioned at varying spacings behind the rotating fan blades to control the level of noise production with minimal effect on the volume of airflow. Various aspects of the fan blade configuration, such as the blade pitch, camber, span, chord, etc., may be manipulated to control the ratio of airflow volume to the amount of noise produced.
