Cooling system for a card rack, and card rack having at least one such system.

摘要

The invention relates to electronic card racks (5) in which it is possible to mount, equally well, cards of conventional technology requiring cooling by forced-air circulation or cards having a heat sink requiring cooling by conduction from the sink towards the slotted backplate serving as support for the card. For this, the cooling devices are formed by slotted backplates (1) pierced with holes enabling air to be blown through the backplate towards the cards; moreover, these backplates comprise a channel (3) for cooling liquid so as to cool the blown air and increase the cooling by conduction in the case of cards having a sink. Application to electronic card racks. <IMAGE>
