Abstract
A gas delivery assembly for a heating or cooling apparatus. The system includes a blower and a duct in fluid communication with the blower (and preferably a plenum in communication with the blower and duct). The duct has a proximal end and a distal end with an inlet opening adjacent the proximal end through which temperature controlled gas enters. The duct further includes a plate extending along its length with a plurality of orifices through which the gas exits the duct. Improved evenness of distribution of gas through the orifices is achieved by the ducts design which includes a first tapered portion adjacent the proximal end and a second tapered portion adjacent the distal end, the first tapered portion having a greater angle of taper than the second tapered portion.
