Air cooling system for a turbocharger driven generator

摘要

A turbocharger arrangement comprises a turbocharger and a generator. The turbocharger comprises a turbine having a turbine wheel and a compressor having a compressor wheel. The turbine wheel and the compressor wheel are mounted to a shaft, the shaft being supported by a bearing assembly located in a bearing housing between the turbine and the compressor, such that the shaft may rotate about an axis; The compressor wheel is between the generator and the bearing assembly; and an inducer portion of the compressor wheel is between an exducer portion of the compressor wheel and the bearing assembly.

1. An engine system comprising an internal combustion engine and a turbocharger arrangement, the turbocharger arrangement comprising:
a turbocharger and a generator; the turbocharger comprising a turbine having a turbine wheel and a compressor having a compressor wheel; the turbine wheel and the compressor wheel being mounted to a shaft, the shaft being supported by a bearing assembly located in a bearing housing between the turbine and the compressor, such that the shaft may rotate about an axis; wherein, the compressor wheel is between the generator and the bearing assembly; and wherein an inducer portion of the compressor wheel is between an exducer portion of the compressor wheel and the bearing assembly; wherein a back face of the compressor wheel is in direct contact with a portion of the generator; wherein the compressor has an inlet and an outlet, wherein the inlet is axially inboard of the compressor wheel; wherein the outlet of the compressor comprises a annular outlet passageway and a volute arrangement around the outlet passageway; and wherein the outlet of the compressor is in communication with an inlet of the internal combustion engine so as to provide compressed air to the internal combustion engine; wherein the inlet has a first end adjacent the compressor wheel and a second end remote from the compressor wheel; and wherein a portion of a wall defining the second end of the inlet is radial with respect to the axis, such that, in use, gas flowing through the second end of the inlet flows in a radial direction with respect to the axis.
