US 10,219,414 B2 · Enhancing cooling efficiency of a computer room air conditioning unit

Abstract

A method for enhancing the cooling efficiency of a computer room air conditioning unit, in a data center, is provided. Raised floor panels are carried on a pedestal support system. The floor panels divide a data center, into upper and lower plenums. A cold aisle is includes air-grate floor panels. The computer room air conditioning unit is operated to condition a heated hot aisle return air flow. A server rack has a front, a back, and side rack support frame members. The support members define an interior server compartment. At least one damper door frame has a top, a bottom and side members. The door frame members define at least one open air flow panel portion. A series of horizontal damper blade members are pivotally mounted in the open panel portion. The damper blade members are pivoted to direct a stream of the conditioned air flow over heat generating components contained in the interior server compartment in order to elevate the temperature of the heated return airflow at the air conditioning unit.

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.
