1. A partition device for improving cooling of a heat-generating electronic device, the partition device comprising:
a grid panel having a plurality of apertures, the grid panel having a thickness extending between a leading surface and a trailing surface, the plurality of apertures extending parallel to an airflow direction of forced air flowing across the thickness of the grid panel and through the plurality of apertures;
a first airflow deflector attached at least in part within one aperture of the plurality of apertures, the first airflow deflector having a first airfoil shape for reducing air resistance between the forced air and the grid panel, the first airfoil shape having a first leading edge that redirects initial contact with the forced air and that extends in a space in front of the leading surface, the first airfoil shape having a first trailing edge that continues redirecting the forced air and that extends in a space in rear of the trailing surface, the first leading edge being joined with the first trailing edge via two first convex surfaces, the two first convex surfaces being outwardly facing and symmetrical relative to a center line of the first airflow deflection; and
a second airflow deflector attached adjacent to the first airflow deflector at least in part within a respective aperture of the plurality of apertures, the second airflow detector having a second airfoil shape, the second airfoil shape having a second leading edge that extends in a space in front of the leading surface, the second airfoil shape having a second trailing edge that extends in a space in rear of the trailing surface, the second leading edge being joined with the second trailing edge via a single second convex surface on one side and via a single flat surface on an opposite side;
wherein the first and second airflow deflectors form an airflow path that includes a high-pressure region and a low-pressure region, the high-pressure region being formed between the first leading edge and the second leading edge, the low-pressure region being formed between the first trailing edge and the second trailing edge, the forced air being drawn from the high-pressure region to the low-pressure region through respective one or more of the plurality of apertures.
