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.
Claims12
A ventilated electronics cabinet for the accommodation of electrical and electronic components, comprising:
- an inner wall and
- an external wall, defining a gap intermediate the inner wall and the external wall;
- an axial fan,
- with a fan intake on the inner wall, and
- a fan axle perpendicular to the inner wall,
- an intake for fresh air, which leads into the gap between the inner wall and external wall,
- a discharge for exhaust from the gap,
- at least one air baffle plate (16)
- located in the gap (4),
- and is aligned in a direction of fresh air flow (10),
- which extends over the fan intake (8)
- at a level of the fan axle (9) and
- which has a height (h) that almost corresponds to the width (b) of the intermediate space (4).
