Abstract
An air inlet diffuseris disclosed for attachment relative to an air inlet openingof an electronics enclosure. The diffuserextends into the electronics enclosureand provides an increased surface area through which EMI attenuating apertures may be formed. The diffuseralso reduces the amount of structure that is disposed within the air inlet openingthereby reducing impedance to airflow through the openinginto the enclosure. The increased surface are of the diffuserallows for increasing the number of EMI attenuating apertures that may be utilized for a given inlet opening. In one embodiment, the total open area of the EMI apertures is greater than the open area of the air inlet opening. In such an embodiment, the EMI apertures provide low impedance to airflow through the diffuserand increased airflow in conjunction with EMI attenuation may be realized.
