  • the cooler for cooling the exhaust gas is usually accommodated in a housing. During operation, the exhaust gas flows through the housing and is cooled by the cooler.
  • the cooler arrangement Owing to the increased temperatures in the exhaust it is customary, in particular on the inlet side of the cooler arrangement, to manufacture the cooler arrangement from metallic components, that is to say components which are manufactured from metal or from an alloy, in order to bring about resistance to the hot exhaust gas. This results in cost-intensive manufacture and/or a design of the cooler arrangement which increases the weight. At the same time, only limited installation spaces are available to such a cooler arrangement. This is the case, in particular, when the cooler arrangement is used in a motor vehicle in which the cooler arrangement is to be configured in a way which is as efficient in terms of installation space as possible.

  • the present invention is based on the general concept of providing in an exhaust gas cooler arrangement, also referred to below in abbreviated form as cooler arrangement, a diffuser which carries the exhaust gas to a cooler and to manufacture said diffuser from an outer wall which is made of plastic and a metallic inner wall.
