Abstract

A computer arrangement includes an electronics enclosure located within a computer housing, which is divided into a plurality of physically separated cooling zones. The enclosure has a plurality of inlet and outlet openings. Each cooling zone is in registration with respective inlet and outlet openings. A backplane is disposed within the electronics enclosure, and has front and rear surfaces. A first electrical component is attached to one of the surfaces and is arranged in one of the cooling zones. At least one circuit board is disposed within the electronics enclosure and is attached to the front surface of the backplane. The circuit board has a second electrical component attached to a surface thereof, which is arranged in another one of the cooling zones. A system operation card is disposed within the electronics enclosure, and is attached to the rear surface of the backplane. A gas moving device is located outside of the electronics enclosure, and is activatable to cause a cooling gas to flow through the cooling zones. The inlet and outlet openings are sized so that the cooling zones receive only an amount of cooling gas necessary to cool the respective electrical components l…
