Patent ID: 7927196

Claim:
A louver module, comprising: a louver module body extending in a length-wise direction, a width-wise direction and a height-wise direction with the length-wise direction, the width wise-direction and the height wise direction oriented perpendicularly relative to one another, the louver module body having a plurality of air passageways extending therethrough generally in the width-wise direction, each one of the plurality of air passageways having at least a serpentine air passageway section formed in a continuously nonlinear serpentine configuration the serpentine air passageway section having an air inlet opening defining an entrance into the serpentine air passageway section and an air outlet opening defining an exit out of the serpentine air passageway section, the air inlet opening and the air outlet opening being disposed apart from one another at a width-wise distance W, the continuously nonlinear serpentine configuration commencing at the air inlet opening, continuing uninterruptedly along the serpentine air passageway section and terminating at the air outlet opening, wherein the serpentine air passageway section includes a first curved air passageway portion curving at a first constantly-changing rate of curvature, a second curved air passageway portion curving at a second constantly-changing rate of curvature and an intermediate curved air passageway portion disposed between, in fluid communication with and connected directly to the first and second curved air passageway portions, wherein the first and second curved air passageway portions are curved in a first direction and the intermediate curved air passageway portion is curved in a second direction generally opposite the first direction, wherein the intermediate curved air passageway portion is generally arc-shaped having an apex, wherein the apex is disposed between but not including the air inlet opening and one half of the width-wise distance W measured from the air inlet opening, and wherein the first constantly-changing rate of curvature is greater than the second constantly-changing rate of curvature to form the continuously nonlinear serpentine configuration to resemble a skewed distribution curve.
