<p>A system for controlling the temperatures of circuit cards in cardcages or other enclosures by controlling the flow of air. More particularly the invention comprises mechanical flow diverters which may divert, deflect, channel or otherwise re-distribute the flow of air to attain a generally common or consistent rate of flow past each circuit card in a cardcage. The invention may be assembled as a discrete part and attached either to the fan, cardcage or other support structure or the invention can be integral part of the cardcage. The invention maximimizes cooling efficiency by modifying the cooling air distribution based on actual requirements and these requirements are proportional to the local heat flux and/or device temperature limits.</p> |
