Abstract:
1. An elongated nozzle for distributing diffused, three-dimensional airflow comprising: a substantially planar exit through which substantially all air exiting the nozzle flows; a plurality of sets of channels, each set comprising a plurality of groups of channels; wherein each set of channels is defined by spaced-apart opposed surfaces extending lengthwise along an elongated length of the nozzle and spaced-apart channel side-walls extending between and arranged substantially orthogonal to the spaced-apart opposed surfaces, the opposed surfaces and the spaced-apart channel side-walls forming the channels of each set, at least one of the spaced-apart opposed surfaces of each set is oriented at a first angle which is non-parallel to an imaginary plane which is substantially orthogonal to the plane of the exit of the nozzle, and extending along the elongated length of the nozzle; wherein, within each set, the spaced-apart channel side-walls of each group of channels are oriented at different second angles, relative to an imaginary plane which is substantially orthogonal to the plane of the exit of the nozzle, and extending along a width of the nozzle, than the spaced-apart channel side-walls of other groups of channels; wherein each channel has its own respective inlet area where airflow enters the channel and its own respective outlet area where the airflow exits the channel, the outlet area being larger than the inlet area to diffuse the airflow as it travels through and out of the channel to provide three-dimensional, diffused, distributed airflow.
