Patent ID: 8118082

Claim:
A heat exchanger for an exhaust gas cooler of an internal combustion engine, comprising: a heat exchanger duct; a bypass duct; and a switching flap arranged in a flow duct upstream or downstream of the heat exchanger, said switching flap dividing a carrier medium flowing to the switching flap between the heat exchanger duct and the bypass duct, and said switching flap adjoined to a separating plate configured to separate the two partial flows, wherein the separating plate extends to a start of the bypass duct, wherein the bypass duct consists of two tubes, an outer tube and an inner tube, which are arranged one inside the other, the carrier medium flowing through a core of the inner tube, wherein the inner tube extends to the separating plate and is connected to the separating plate, and wherein the separating plate forms an end wall, which is aligned vertically relative to the flow direction, and includes an aperture into which the inner tube terminates, wherein the outer tube is separated from the end wall of the separating plate such that there is a space between the outer tube and the end wall in an axial direction of the heat exchanger.
