A backflow blocking apparatus for axial fans may be provided. The apparatus may comprise a sheet. The sheet may comprise a first section and a second section. The first section may comprise a plurality of flaps cut out of and retained by the first section of the sheet. The second section may comprise a guard structure. The apparatus may further comprise a fold about which the first section and the second section are folded on one another. The guard structure may inhibit the movement of the plurality of flaps in a direction toward the guard structure when the first section and the second section are folded on one another.

Backflow blocking device for axial fans

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.
