Back mounted electronic circuit air cooling system - has water cooled heat exchanger pipe loop connected to flow pipes with top and bottom plate air ducts

摘要

The air cooling system for rack mounted electronic circuit card cabinets uses water cooled heat exchanger modules to provide a uniform effect. The system performance is independent of the spacing of the circuit cards. A double cabinet (1) has turn racks each holding a number of circuit cards (3, 4). Located between each rack module is a water cooled heat exchanger with a pipe loop connecting to in and outflow pipe s at either side of the cabinet. Top and bottom plates have a series of small holes for the air flow. Air is ducted up through one cabinet from blowers (6) and down through the other to a discharge manifold (12).
