Abstract
EMI-attenuating air ventilation panel for electrical and electronic systems. An opening through a metallic panel is realized using an extrusion method in order to obtain a tube leaving the opening at one end. The periphery of the opening at the other side of the extruded tube has a smooth edge in order to improve air circulation. A multitude of such extruded holes are critically placed on the panel to form an array. The panel in turn is mounted in an electrical or electronic system to allow air cooling while the extruded tubes attenuate EMI radiation to and from electrical circuits.
