Abstract
The invention relates to a heat exchanger (10), in particular, for exhaust coolers on internal combustion engines. The aim of the invention is to provide a separation of the carrier medium flow into two partial flows as leak free as possible, by suitable embodiment of the baffle plate (40). A heat exchanger (10), as used, in particular, as exhaust gas cooler for internal combustion engines, comprises a heat exchanger channel (14) and a bypass channel (11), whereby a switching flap (20) is arranged upstream of the heat exchanger (10) in the flow channel (25), which divides the incoming carrier medium into the heat exchanger channel (14) and the bypass channel (11). A baffle plate (40) is provided to maintain the separation between the partial flow through the bypass channel (11) and the partial flow through the heat exchanger channel (14), which, according to the invention, extends from the switching flap (20) to the beginning of the bypass channel (11).
