摘要： A fan assembly includes a fan and a fan drive. The fan includes a fan hub located at a fan central axis, and a plurality of fan blades extending outwardly from the fan hub. The fan hub has a fan hub opening at the fan central axis. The fan hub opening is at least partially defined by a plurality of nodes extending radially inwardly toward the fan central axis from the fan hub. The fan drive is installed in the fan hub opening via an interference fit between the plurality of nodes and an outer surface of the fan drive, thus centering the fan drive in the fan hub opening.

摘要： An integrated diffuser grille for a coil unit includes a hub, a stack diffuser wall, a plurality of radial spokes extending between the hub and the stack diffuser wall, and a plurality of partial spokes extending inwardly from the stack diffuser wall. A radial length of the partial spokes is less than a radial length of the spokes. A plurality of circumferential elements is connected to the plurality of radial spokes between the hub and the stack diffuser wall. At least one circumferential element is connected to the plurality of partial spokes and at least one circumferential element has a non-uniform configuration about a circumference of the plurality of circumferential elements. A cross-section of the plurality of radial spokes has an airfoil-shape and at least one of a spoke pitch angle, camber angle, and chord of the airfoil-shape varies over a radial length of the plurality of spokes.
