Claims17
An airflow distribution device comprising:
- a plenum chamber having an inlet and an outlet and walls for confining a flow of air, whereby said walls form a base at said outlet;
- a stationary diffuser plate connected to said base positioned over said outlet of said plenum chamber, said stationary diffuser plate having a plurality of dimples, each of said dimples having a side opening;
- and
- a flat angle deflection plate having a plurality of openings positioned within said plenum chamber and over said diffuser plate, said plurality of openings of said flat angle deflection plate being in communication with openings of said dimples of said stationary diffuser plate but do not overlay a horizontal projection of said openings in said diffuser plate for distributing air substantially parallel to said base of said airflow distribution device.
