Abstract
A compressor bearing cooling inlet plate has a mount plate, and a boss extending forwardly from the mount plate. The boss includes a plurality of grooves extending axially into the boss to define flow passages for cooling air from an outer peripheral surface of the cooling inlet plate to an inner bore. The grooves extend for a width between side walls, at angles that are not directly radially inwardly toward a center axis of the cooling plate. There is a plurality of widths across the plurality of grooves. A compressor bearing assembly, a motor driven compressor for use in a nitrogen generation system, and a method of installing a compressor bearing cooling inlet plate are all also disclosed and claimed.
