Abstract: A ventilation unit for operative arrangement within an electronic apparatus. This unit has: an exterior side having a first exhaust port separated from, and located in stacked relationship with, a second exhaust port; and a first and second powered air mover, each having an intake side oriented at an angle greater than zero degrees from the exterior side. The first powered air mover intake side is in communication with the first exhaust port. One powered air mover can be located closer to the exterior side than the other. Gas, such as air, removed from the electronic apparatus can be drawn in through an intake side of the second powered air mover, then directed through a duct cover before it flows between a covered side of the first powered air mover and a support member side of the unit. The angle of orientation is preferably between twenty and one-hundred degrees. Additional powered air movers can be accommodated, each with a respective exhaust port.
