The grill contains openings to promote ventilation within the apparatus, and the ventilation materials allows for air flow despite being visually opaque.
A flow direction control device (11) for controlling the direction of the air flow from a cross flow fan (12).
The mass exchange comprises plural blood flow conduits (10a, 10b, 10c) for defining blood flow; and plural air flow conduits (20a, 20b, 20c) for defining air flow.
The filter assembly is tapered to create a large volume air way downstream from the filter assembly that enables more even air flow and filter loading.
The invention relates to a rotor blade (10) for a wind power plant having a vane (20) arranged on a surface (12) of the rotor blade (10) for influencing an air flow on the surface (12) of the rotor blade (10).
The first portions of the airfoils provide cooling airflow over the engine and structural support for the second portions.
Each interlocking wall strip (23) having multiple apertures (20) defined within to allow for free airflow around, through and between each compartment (25).
A part or all of each of the ducts (5, 5) comprises a laminar flow part in which the flow of the air is formed in a laminar flow.
The low airflow region is configured to direct air toward the high temperature region.
The air diffuser has a high airflow region (62) and a low airflow region (64).
Part or all of each duct (5, 5) is provided with a laminar airflow section that causes the air to form a laminar flow.
The sidewalls deflect transverse airflow across the accumulation area and the cover allow for longitudinal airflow.
