Abstract
A chassis panel for a computerized device includes ventilation elements that visually obscure electronic components disposed within an associated chassis and that minimize airflow resistance. Each ventilation element includes a first angled ventilation portion having openings that provides limited visual access to the electronic components disposed within the chassis. Each ventilation element also includes a second angled ventilation portion having openings that provide no visual access to the electronic components disposed within the chassis. As such, the ventilation elements visually obscure the electronic components disposed within the chassis without the need for additional materials such as screens, mesh, or foam. Also, the openings of the first and second ventilation portions provide the chassis panel with a relatively large free area ratio, such as between about 42% and 48% or greater depending on hole pitch values and opening sizes. As such, the ventilation elements help to maximize air flow through the chassis to allow cooling of the electronic components disposed therein.
