Abstract
In a double-walled electronics cabinet 1 an axial fan 5 is inserted in its inner wall 2. In order to prevent the creation of air eddies in front of the fan intake 8, an air baffle plate 16, which is in direction of flow, is located over the fan intake 8 in the gap 4 between inner wall 2 and external wall 3. The efficiency of the axial fan 5 is crucially improved by the division of the flow of fresh air, and the creation of air eddies and differences in pressure are purposefully avoided.
