Abstract
The card cage is provided with an air cooling system employing deformable baffles in the air flow path to the spaces between the printed circuit cards. The baffles are deformed upon assembly in order to adapt to the thermal conditions to be expected during operation of the card cage. The baffles provide minimum openings which produce a pressure in front of the openings which effects a more uniform flow distribution via the openings and which also permits an increase in the air flow rate to the printed circuit cards which are subject to strong thermal stresses.
