Abstract
A compressor device includes a motor cooling system that provides a first flow of a first fluid through a housing for cooling a motor. The motor cooling system includes a first fluid flow section at a first axial position. The first fluid flow section extends in a downstream direction radially with respect to the axis of rotation. Also, the device includes a bearing cooling system that provides a second flow of a second fluid through the housing for cooling the bearing. The bearing cooling system includes a second flow section at a second axial position that is spaced apart axially from the first axial position. The second flow section extends in a downstream direction radially with respect to the axis of rotation. The first flow section and the second flow section are disposed in a heat exchanger arrangement configured to transfer heat between the second fluid and the first fluid.
