EXHAUST GAS COOLER

摘要

The invention relates to an exhaust gas cooler (1) having an outer housing (2) and a heat exchanger insert (3) which is arranged therein and has pipes (5) around which exhaust gas flows transversely in an inner housing (4) and through which a coolant of a first cooling circuit (11) flows. It is essential to the invention that the outer housing (2) is cooled by a second cooling circuit (10) which is separate from the first cooling circuit (11). This in particular can reduce the temperature load.
