Abstract
Methods and systems are provided for cooling a compressor in an engine. In one example, a compressor with a liquid coolant passage extending through a section of a housing of the compressor adjacent to a bypass passage, is provide. The bypass passage enable airflow to be directed around a portion of a compressor impeller.
Claims20
A compressor comprising:
- an impeller receiving air from an inlet passage;
- a housing surrounding the impeller;
- a bypass passage including:
- a first passage port positioned downstream of a leading edge of the impeller;
- and
- a second passage port positioned upstream of the leading edge;
- and
- a liquid coolant passage including an inner section extending through a section of the housing and positioned radially inward from the bypass passages;
- where the inner section extends upstream from the leading edge of the impeller and where upstream is a direction opposing a general direction of airflow through the inlet passage during compressor operation.

A method for operating a compressor in an engine turbocharger, comprising:
- flowing air through a bypass passage including a passage inlet downstream of a leading edge of an impeller and a passage outlet upstream of the leading edge;
- and
- flowing coolant through an inner section of a liquid coolant passage extending through a section of a housing and positioned radially inward from the bypass passage;
- where the inner section extends upstream from the leading edge of the impeller and where upstream is a direction opposing a general direction of airflow through an inlet passage of the impeller during compressor operation.

A compressor cooling system, comprising:
- a liquid coolant passage extending through a portion of a housing and including an inner section positioned radially inward from a bypass passage, where the bypass passage extends upstream and downstream of a leading edge of an impeller;
- and
- a pump in fluidic communication with the liquid coolant passage;
- where the inner section extends upstream from the leading edge of the impeller and where upstream is a direction opposing a general direction of airflow through an inlet passage of the impeller during compressor operation.
