Abstract

The disclosure relates to an exhaust gas cooling device for an internal combustion engine, having a housing which can be connected to an exhaust gas line of the internal combustion engine and has an axis of symmetry and having a Venturi assembly coupled to the housing for introducing exhaust gas and ambient air and having an outlet line emitting an exhaust gas-ambient air mixture into the environment, wherein: the Venturi assembly has a Venturi channel which can be coupled fluidically to the exhaust gas line and an inlet opening delimited by the Venturi channel and the exhaust gas line for ambient air; the Venturi channel is used to conduct an exhaust gas-ambient air mixture and opens, with the inlet opening, into a mixing chamber; the Venturi channel has an outlet opening and the outlet opening has an inflow opening, wherein the outlet opening and the inflow opening are spaced apart from one another; the Venturi channel and the outlet line, with the inflow opening, open into the housing.
