Abstract
An EMI shield for an electronic system enclosure is disclosed. The EMI shield may include an electrically conductive panel with a plurality of air ventilation channels, which has an upstream airflow side and a downstream airflow side. The EMI shield may also include a first air ventilation channel with a first cross-sectional shape having a first cross-sectional area and a first depth. The EMI shield may further include a second air ventilation channel with a second cross-sectional shape, having a cross-sectional area greater than the first cross-sectional area, and a second depth larger than the first depth.
