  • Banded cooling fan band having knit-line strength improvement
    Patent number: 11898569
    Abstract: A fan includes a hub configured to be driven by motor to rotate about a fan rotational axis, blades that protrude radially from the hub and a band that surrounds the rotational axis and connects the tips of the blades. The band includes structurally-reinforcing ribs that protrude from the hub-facing surface of the band. A rib is disposed between respective tips of each pair of adjacent blades. Each rib bridges a knit-line of the band, and has a circumferential dimension that is at least 40 percent of a distance between the respective tips of the adjacent blades.
