A heat exchanger for an internal combustion engine includes a first flow channel; a second flow channel arranged adjacent to the first flow channel; a line separate from the second flow channel; and a valve channel in which an adjustable valve element is disposed. The valve channel is arranged upstream of the first and second flow channels and an inlet channel is arranged upstream of the valve channel in a flow direction of exhaust gas. The valve element includes a baffle plate, the baffle plate having an end portion that extends diagonally in the valve channel with respect to the flow axis of the first flow channel. The valve element includes a flap that is pivotably mounted at the end portion of the baffle plate such that the flap is pivotable about an axis that extends in a direction of a width of a common housing.

Heat exchanger for internal combustion engines

The invention relates to a heat exchanger (), 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 (). A heat exchanger (), as used, in particular, as exhaust gas cooler for internal combustion engines, comprises a heat exchanger channel () and a bypass channel (), whereby a switching flap () is arranged upstream of the heat exchanger () in the flow channel (), which divides the incoming carrier medium into the heat exchanger channel () and the bypass channel (). A baffle plate () is provided to maintain the separation between the partial flow through the bypass channel () and the partial flow through the heat exchanger channel (), which, according to the invention, extends from the switching flap () to the beginning of the bypass channel ().

Heat exchanger in particular for exhaust coolers on internal combustion engines

In a heat exchanger used especially as an exhaust heat exchanger, provision is made for tube sheets, the tubes of a tube bundle, and a housing to be shaped from stainless steel sheets. The tube sheets are formed as deep-drawn and stamped parts, each of which has a circumferential wall that projects outward beyond the ends of the tubes in the tube bundle. The walls are welded to the housing, and each of the walls is abutted by a diffuser.

Exhaust heat exchanger

A process for mounting lugs or projections on a thin metal sheet, by forming the lugs and/or projections out of the thin metal sheet by way of massive forming. Such a thin metal sheet in the form of a thin sheet metal strip is used preferably for forming rectangular tubes for an exhaust gas heat transfer device which, for guiding the exhaust gas, is provided with a bundle of these rectangular tubes.
