摘要
An apparatus suitable for providing ventilation and electromagnetic interference (EMI) containment for a computing device includes a first strip and a second strip. The first strip is sized to span ventilation openings of a computing device covering. The second strip intersects the first strip while also spanning the ventilation openings. Thus, the first strip and the second strip cooperate to define airflow openings within the ventilation openings, the airflow openings being sized to inhibit EMI from exiting the computing device via the ventilation openings.

The present disclosure relates to high performance and high density computing solutions, such as line cards and computing blades, and in particular to cooling these computing solutions while providing optimized electromagnetic interference (EMI) shielding.
Over the past several years, the information technology field has seen a tremendous increase in the performance of electronic equipment coupled with a decrease in geometric floor space to house the equipment. Further, increased performance requirements have led to increased energy use, resulting in increased heat dissipation within the crowded floor space. Put another way, application-specific integrated circuit (ASIC)/field-programmable gate array (FPGA) technology has been advancing per Moore's law, while, unfortunately, cooling technology (e.g., fan technology) has not improved at the same pace (e.g., due to limitations associated with acoustic and thermal impedance). Moreover, cooling passages are often limited by electromagnetic interference (EMI) constraints, which often limit the size of openings that can be included on a computing device's covering. As a result, there is a demand for improved thermal management solutions for computing components and/or computing components with improved thermal characteristics.
