Abstract
A turbocharger compressor and method are provided including a first coolant passage in thermal contact with an inlet configured to direct the charge gas toward an impeller; and second, third, and fourth coolant passages respectively in thermal contact with impeller, volute, and diffuser regions. All of the coolant passages are fluidically coupled with a heat exchanger. One or more of the coolant passages are configured such that coolant flows in an upstream direction relative to a general flow direction of charge gas through the compressor.
Claims20
A turbocharger compressor comprising:
- an inlet configured to intake a charge gas at a first end and to direct the charge gas toward an impeller, a first coolant passage in thermally conductive contact with the charge gas in the inlet and fluidically coupled with a heat exchanger;
- an impeller region surrounding the impeller downstream from the inlet, a second coolant passage in thermally conductive contact with the impeller region and fluidically coupled with the heat exchanger;
- a diffuser region downstream from the impeller region, a third coolant passage in thermally conductive contact with the diffuser region and fluidically coupled with the heat exchanger;
- and
- a volute region downstream from the diffuser region, a fourth coolant passage in thermally conductive contact with the volute region and fluidically coupled with the heat exchanger.
A compressor housing for compressing charge air for an internal combustion engine comprising:
- an inlet region having an opening at an upstream side and having a downstream side at an inducer area of an impeller blade;
- an impeller region surrounding the impeller blade downstream from the inlet region;
- a diffuser region downstream from the impeller region;
- a volute region downstream from the diffuser region;
- a coolant passage in the inlet region in thermally conductive contact with the charge air within the inlet region wherein a coolant fluid flows in an upstream direction relative to a general flow direction of the charge air.
A method a compressor an engine in a hybrid, comprising:
- passing a coolant through a first passage in thermal contact with an inlet passage interior surface in an upstream direction relative to a general flow direction of the charge air;
- absorbing heat from at least a recirculating portion of charge air flow;
- and
- moving the absorbed heat away from the inlet passage via the coolant to a heat exchanger.
