ABSTRACT:
A fan-shroud structure10includes a fan12mounted for rotation about an axis B. The fan has a plurality of blades20with tips of the blades being coupled to an annular band22. A shroud26, including an annular labyrinth seal28, is disposed generally adjacent to the annular band thereby defining a gap30between the annular band and the seal. The seal has a corrugated profile and is constructed and arranged to provide resistance to air flow as air swirls and flows back into the gap and to minimize air leakage across the gap.
