Low profile liquid cooled server heat sink

摘要

A computer assembly ( 20 ) including a casing ( 22 ) having a bottom ( 24 ) and end walls ( 26 ) and side walls ( 28 ) and a lid ( 30 ) and a variety of computer components are supported on the bottom ( 24 ). A partition ( 38 ) extends between the side walls ( 28 ) and a plurality of fans is disposed in the partition ( 38 ) for moving air through perforations ( 32 ) in the end walls ( 26 ). A heat exchanger ( 44 ) includes fins ( 48 ) and each fan has a central hub ( 52 ) and fan blades extending radially therefrom. In the embodiment of Figures 1 and 2, the fans move air into said fins ( 48 ) and a flow straightener ( 56 ) is disposed between the hub ( 52 ) of each fan and the fins ( 48 ) for straightening flow downstream of the hub ( 52 ) prior to entering said fins ( 48 ). In the embodiment of Figures 3 and 4, the fans move air through the fins ( 48 ) and into a flow deflector ( 58 ) over each hub ( 52 ) of the fan for diverting flow from the fins ( 48 ) and around the hubs ( 52 ) prior to entering the fans.
