AIR COOLING SYSTEM FOR ELECTRIC ASSISTED TURBOCHARGER

摘要

A system for controlling the temperature of an electric motor in an electric assisted turbocharger (10) that is coupled to an internal combustion engine (14) has a turbocharger (10) with an electric motor disposed within a motor housing (20). The motor housing (20) has a motor housing inlet (40) and a motor housing outlet (46). The turbocharger (10) has a compressor (16) with a compressor inlet and a compressor outlet (26). The turbocharger also has a turbine (18). A first cooling hose (34) is coupled to the compressor outlet (26) and coupled to the motor housing inlet (40). A second cooling hose (36) is coupled to the motor housing outlet (46) and coupled to the compressor inlet.
