Patent ID: 8641492

Claim:
A directional flow raised floor air-grate for the enhanced thermal management of airflow in a data center, comprising: (a) a top plate having a plurality of clear shots, an upper working surface, a lower surface, and four corners; (b) a load bearing frame connected to said lower surface of said top plate, said load bearing frame comprising four vertical girder members, and a plurality of vertical reinforcing beam members, wherein said girder members are connected to said top plate in a ninety-degree alignment so that said girder members are capable of supporting said top plate as an air handling separation barrier, between a cold air flow in a lower plenum and a warm air flow in an upper plenum, on a raised floor pedestal support system, and said plurality of vertical reinforcing beam members are connected to said girder members in a longitudinal spaced relationship; (c) at least two vertical airfoil vane members, each of said airfoil vane members having an upper edge, a lower edge, and a bend formation positioned along a longitudinal axis thereof, said bend formation defining an upper inclined surface, and a lower vertical surface, said upper inclined surface having an upper edge positioned adjacent to said lower surface of said top plate, and said lower vertical planar surfaces having a lower margin adapted to extend deeper into said lower plenum than said reinforcing beam members to transversely interrupt a direction of said cold air flow in said lower plenum, and whereby said vane members are connected to said load bearing frame in a crosswise spaced relationship to said reinforcing beam members; and (d) a plurality of open, but not dampened, airflow channels established between wither of said girder and reinforcing beams members of said framework, and said airfoil vane members, said channels capable of tunneling a flow of said transversely interrupted airflow of said cold air from said lower plenum, and ducting said interrupted airflow past said upper inclined surface of said airfoil van members, and through said slots in said top plate on an inclined plane.
