Claim of US Patent No. 9,968,007

1. A rack assembly for storage of a plurality of servers each having a top and a bottom walls, said rack assembly comprising:a rack body which has therein a storage space extending in an upright direction, and which is configured to hold the plurality of the servers in said storage space such that the servers are displaced from each other in the upright direction by a passageway which extends in a transverse direction transverse to the upright direction to terminate at an inlet and an outlet, and which is defined by the bottom wall of a first one of the servers and the top wall of a next one of the servers; and
a fluid generating device including
at least one partition wall which is disposed in said passageway and which extends in the transverse direction to terminate at proximal and distal marginal edges which are adjacent to said inlet and said outlet, respectively, said partition wall dividing said passageway into an inflow path and at least one outflow path disposed downstream of said inflow path, said partition wall having a plurality of internal ports each of which is disposed downstream of said inflow path and upstream of said outflow path,
at least one proximal barrier extending from said proximal marginal edge toward one of (1) the bottom wall of the first one of the servers and (2) the top wall of the next one of the servers, and
a distal barrier extending from said distal marginal edge toward the other one of (1) the bottom wall of the first one of the servers and (2) the top wall of the next one of the servers, whereby
when cooling air is drawn into said inflow path through said inlet, the cooling air is blocked by said distal barrier such that the cooling air is forced to flow into said outflow path through said internal ports to generate a plurality of cooling air jets, which impinge on said one of the bottom wall of the first one of the servers and the top wall of the next one of the servers before flowing out through said outlet,
wherein said proximal barrier extends from said proximal marginal edge to abut against one of (1) the bottom wall of the first one of the servers and (2) the top wall of the next one of the servers so as to ensure that the plurality of cooling air jets flow out of said outflow path through said outlet.
