Muffler

摘要

The silencer has a sound damping device arranged in a silencer housing (5). A refrigeration element (2) e.g. heat exchanger, is arranged in the silencer housing, where the refrigeration element extracts heat energy from exhaust gas. A high temperature side of the refrigeration element transfers the heat. A low temperature side of the refrigeration element is shielded by the exhaust gas. A gas pipe duct (1) is arranged in a flat channel. The pipe duct is connected to the refrigeration element at the high temperature side.
