Heat exchanger for motor vehicle, has envelope housing heat exchange pipe, and semi-cases including extensions to delimit respective free spaces, which constitutes inlet and outlet channels and forms exhaust gas deviation channel

摘要

The heat exchanger has a heat exchange pipe (2) through which a gas to be cooled passes. An envelope (5) with an upper semi-case (46) and a lower semi-case (47) houses the pipe. The semi-cases have an extension (59), which delimits a free space (15) constituting inlet and outlet channels. The semi-cases have another extension (59), which delimits a free space (17) forming an exhaust gas deviation channel.
