INGESTED TURBULENCE SUPPRESSION RIM STRUCTURE FOR AXIAL FLOW FAN |
摘要 |
A fan structure includes a fan having a hub, a plurality of blades attached circumferentially to the hub, and a ring, concentric with the hub, joining tips of the blades. A shroud of the fan structure includes a base having an upstream side constructed and arranged to face a radiator and a downstream side opposite the upstream side; an annular member extending generally transversely from the downstream side of the base and defining a generally central annular opening sized to accommodate the ring of the fan; and rim structure extending generally transversely from the upstream side of the base and disposed circumferentially around a periphery of an inlet of the fan so as to reduce radial airflow from entering the fan. |
