Abstract
A compressor adapted to compress a working fluid includes a housing surrounding a compressor wheel and a backplate connected to the housing and enclosing the compressor wheel within an interior space of the housing. A cooling fluid conduit is fluidly connected between a cooled and compressed source of working fluid downstream of the compressor and the interior space of the housing of the compressor at a location between the compressor wheel and the back plate. A pressure differential created when the compressor is operating draws a flow of cooled, compressed charge into the interior space of the housing, which flow passes over and convectively cools said compressor wheel before mixing with a main compressor flow and being provided back through the compressor outlet.
