An air inlet grille for an appliance onboard an aircraft includes a screen having an inside-facing surface and an outside-facing surface, a plurality of airflow openings formed within the screen between the inside-facing surface and the outside-facing surface, and a plurality of tubes disposed on the inside-facing surface of the screen where openings on one end of the plurality of tubes are aligned with the plurality of airflow openings. A length of the plurality of tubes is at least twice a diameter of the plurality of airflow openings with which the plurality of tubes is aligned. |
