An enclosed, electronic system has a plurality of lower power-dissipating electronic components mounted on a chassis. The components are positioned adjacent each other to form low volume fluid ducts therebetween. A low volume fluid duct is formed between one side of the plurality and one end enclosure of the system. At least one higher power-dissipating electronc component is also mounted on the chassis, forming a high volume fluid duct between one of its sides and one side of the last of the lower power-dissipating electronic components, and a high volume fluid duct also formed between the other side of the higher power-dissipating electronic component and the other end enclosure. Air is caused to blow through the low volume fluid duct and then to be exhausted through the high volume fluid ducts. The rate of air flow through the high volume ducts is one half of the minimum required to cool the higher power-dissipating component. The rate of air flow through the low volume fluid ducts is at least one half of that required to cool each of the lower power-dissipating electronic components. By exhausting the cooling air from the low volume fluid channels through the high volume fluid ducts, the air flow required is less than the total required for the low volume fluid ducts plus the high volume fluid ducts.

An enclosed computer cabinet having at least one chassis, first and second end enclosures, and intake and exhaust air vents, comprising: (a) a plurality of lower power-dissipating electronic components mounted adjacent each other on the chassis forming low volume air ducts between each other and between the first end enclosure and one side of the adjacent lower power-dissipating electronic components; (b) at least one higher power-dissipating electronic component mounted on the chassis, adjacent the second end enclosure, to form a high volume duct with one side of the higher power-dissipating electronic component; (c) deflector means, positioned between the lower power-dissipating electronic component furthest from the first end enclosure, to form a low volume air duct with one side of the furthest lower power-dissipating electronic component, and to form a high volume air duct with the other side of the higher power-dissipating electronic component; and (d) tangential fan means positioned to cause air to be drawn into the low volume ducts over both sides of each of the lower power-dissipating electronic components, and to exhaust through the high volume ducts over both sides of the higher power-dissipating electronic component, the rate of air flow in the high volume ducts being a minimum of one half of that required to cool the higher power-dissipating electronic component, and the rate of air flow in the low volume ducts being at least one half of that required to cool each of the lower power-dissipating electronic components.
