1. A method of enhancing the cooling efficiency of a computer room having computer equipment in computer equipment racks arranged in rows between a cold aisle and a hot aisle comprising:forming a lower plenum in said computer room using raised floor panels, said raised floor panels having slots formed in a top plate, said slots aligned in said top plate in longitudinal directions that are parallel;
supplying cooling air to said lower plenum that pressurizes said lower plenum with said cooling air and causes said cooling air to flow through said lower plenum;
directing said cooling air flowing in said lower plenum onto stationary air foil vanes that have stationary vertical surfaces and stationary inclined surfaces, said stationary vertical surfaces redirecting said cooling air flowing in said lower plenum in an upward direction towards said stationary inclined surfaces, said stationary inclined surfaces perpendicular to said longitudinal direction of said slots so that said inclined surfaces redirect said cooling air through said slots in said longitudinal directions;
aligning said raised floor panels so that said longitudinal directions of said slots in said top plate are directed towards said computer equipment racks in said cold aisle and said cooling air flowing through said slots is directed towards said computer equipment racks.
