Engine-cooling fan assembly with overlapping fans |
摘要 |
An automotive engine-cooling fan assembly uses pairs of overlapping fans to improve flow uniformity through the heat exchanger cores and to maximize the amount of fan power that can be achieved with limited motor sizes. One fan of each pair has upstream supports and the other has downstream supports, and these supports are so configured to minimize the axial dimension of the assembly. The use of banded fans maximizes fan performance, and blade skew minimizes fan noise.
