Fan unit for providing improved airflow within display assemblies

A fan unit for improved airflow within a display assembly having a subassembly comprising an electronic display layer, said fan unit comprising:

• centrifugal fans;
• and
• a common housing for said centrifugal fans forming a ducted passageway for exhaust from said centrifugal fans, said common housing comprising an upper surface with openings, each aligned with an intake of a respective one of said centrifugal fans, a leading surface extending at a non-zero, non-perpendicular, non-180-degree angle from a forward portion of the upper surface and forming, at least in part, an exit to the common housing for the exhaust from said centrifugal fans, and a rear wall extending along and from a rear edge of the upper surface to a rear panel of the subassembly of the display assembly comprising the electronic display layer when the fan unit is installed at the display assembly;
• wherein the centrifugal fans are spaced apart along a longitudinal axis of the common housing;
• wherein the rear edge of the upper surface forms a wave shape such that the upper surface defines peaks, each accommodating a respective one of said openings, said peaks of the upper surface being spaced apart from one another, in their entireties, by a valley extending between adjacent ones of said peaks;
• wherein the rear wall comprises a plurality of distinct segments, each comprising a distinct panel, collectively forming the wave shape and thereby defining said peaks, each accommodating a respective one of said centrifugal fans, and being spaced apart from one another, in their entireties, by a valley extending between adjacent ones of said peaks, said valley comprising a longitudinally extending one of the segments comprising a planar panel;
• and
• wherein the valley of said rear edge of said upper surface as well as the valley of said rear wall each extend forward of a lateral midline of each of said fans so as to be closer to the forward portion of said common housing than to said peaks of said upper portion and of said rear wall.
