Compressor for turbocharging vehicle engine, includes segments with cooling channels and optional heat exchanger, to reduce temperature of air charged to engine

摘要

The compressor includes segments (6) to cool air charged to the engine, within its casing (2). The segments have channels (7), through which a coolant flows. Tips of the segments are designed to reduce resistance to airflow. Numbers of segments are arranged with spacing between them. The compressor casing is a spiral housing with a rectangular connecting flange outlet (9). The rotary impeller (5) of the compressor is driven by a turbine. A heat exchanger cools the air charged, and is mounted at the flange, or within the casing.
