Low profile liquid cooled server heat sink

摘要

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