Disclosed is a heat exchanger, especially an exhaust gas heat exchanger, comprising a housing () which can be penetrated by at least one first medium (M) and at least one second medium (M), and at least one sealing element (). At least one flow means (), around which the second medium flows, is provided inside the housing, said flow means improving heat transfer from the first medium to the second medium.

Heat exchanger, method for the production of a heat exchanger

A collecting box of a heat transfer device has a lengthwise partition in a collecting box between two rows of flat tubes. The tubes are designed as multichannel tubes that are divided by at least one lengthwise separating rib positioned at the level of the at least one lengthwise partition into a number of channels that corresponds to the number of collecting chambers. The at least one lengthwise partition is provided with its edge facing the tube ends with recesses with the spacing of the multichannel tubes. The recesses fit over the separating ribs of the multichannel tubes in a shapewise and flush manner and are connected tightly with the outside contours of the tube ends. In preferred embodiments the parts are made of metal and brazed together.
