ABSTRACT:
The present disclosure describes an air cooling system which has the ability to maintain acceptable temperature levels in present day high density electronic equipment. More specifically, the system provides an arrangement whereby each printed circuit card has its own ducting structure affixed thereto to form an integral unit. Cooling air streams are directed simultaneously from individual apertures in the ducting structure upon a respective plurality of integrated circuit package assemblies mounted on the card.
