Abstract

A parallel cooling system is shown in its side view of Fig. 1 and its back view in Fig. 2. The method of air distribution is as follows. Fresh cooling air is drawn into the bottom of the electronic gate frame by blowers 10 and is delivered to the cards 11 through the common air-supply duct 12, as indicated by the arrows. The cards 11 contain a plurality of modules 20. Some of the air is deflected over the bottom row of cards 11 and exhausted through the exhaust opening 13 for that row. The remaining cooling air continues up through the common air-supply duct. Some of this air is deflected over the second row of cards 11 by the projection plate 14 and is exhausted through the exhaust duct 15. The same procedure applies to the remaining rows of cards.

Parallel Air Cooling for Planar Package Devices

A parallel cooling system is shown in its side view of Fig. 1 and its back view in Fig. 2. The method of air distribution is as follows. Fresh cooling air is drawn into the bottom of the electronic gate frame by blowers 10 and is delivered to the cards 11 through the common air-supply duct 12, as indicated by the arrows. The cards 11 contain a plurality of modules 20. Some of the air is deflected over the bottom row of cards 11 and exhausted through the exhaust opening 13 for that row. The remaining cooling air continues up through the common air-supply duct. Some of this air is deflected over the second row of cards 11 by the projection plate 14 and is exhausted through the exhaust duct 15. The same procedure applies to the remaining rows of cards. In this way, each row of cards receives cooling air at the same cool temperature, rather than preheated by previous rows as in the serial method of cooling. This parallel air distribution system has the unique feature of requiring low-static pressure at the source. The cable raceways 16 contain the electrical cables 17. Doors 18 allow access for servicing to the cooling system.
