Abstract
A heat exchanger is disclosed for the exhaust gas train of a motor vehicle. The heat exchanger includes a bundle of separately formed exhaust gas carrying exchanger tubes that is disposed in a closed housing formed separately, a coolant flowing through the housing and around the outside of the exchanger tubes. A bandage is disposed on the bundle of exchanger tubes mechanically connecting a plurality of the exchanger tubes to militate against an oscillation of the exchanger tubes.

A heat exchanger for the exhaust gas system of a motor vehicle comprising:
- a closed housing;
- a bundle of separately formed exhaust gas carrying exchanger tubes disposed in the housing and conducted through a wall of the housing, wherein a coolant flows through the housing and around an outer surface of the exchanger tubes;
- and
- a bandage disposed on the bundle of exchanger tubes connecting a plurality of the exchanger tubes.
A heat exchanger for the exhaust gas system of a motor vehicle comprising:
- a housing having a coolant inlet and a coolant outlet to cause a coolant to flow therethrough;
- a bundle of separately formed exhaust gas carrying exchanger tubes disposed in the housing and conducted through a wall of the housing, a first end and a second end of the exchanger tube disposed outside of the housing, wherein the coolant flows through the housing and around an outer surface of the exchanger tubes;
- a bandage surrounding at least a portion of the bundle of exchanger tubes and connecting a plurality of the exchanger tubes, the bandage including a resilient mechanical abutment to mechanically interconnect connect the bandage and the plurality of the exchanger tubes to the housing;
- a stiffening element disposed within the bundle to mechanically interconnect a plurality of the heat exchanger tubes;
- and
- a baffle disposed within the bundle of tubes to guide the flow of the coolant in the housing, the baffle being mechanically connected to a plurality of exchanger tubes and the housing.
