A flat tube for an exhaust gas cooler including two flat wide sides and two rounded narrow sides. The flat tube further including a plurality of moulded turbulence projections arranged on the two wide sides in two flow rows and projecting from a respective one of the two wide sides toward the other of the two wide sides. The plurality of turbulence projections are respectively structured in an elongated manner and arranged at an angle relative to a longitudinal direction. The flat tube also including a plurality of moulded support projections projecting from a respective one of the two wide sides away from the other of the two wide sides. The plurality of support projections are arranged between the two flow rows. The two narrow sides each have an elongated flat region that merges into the two wide sides via a plurality of rounded corner regions.

Flat tube for an exhaust gas cooler

The invention relates to a flat pipe, comprising two substantially flat first walls that are opposite each other and arranged parallel to each other, two arcuate second walls that connect the two flat first walls, and an interior through which a medium can flow, wherein projections that protrude into the interior are provided in at least one of the flat first walls, wherein projections that protrude into the interior are provided in the arcuate second walls.

Flat pipe

The invention relates to an apparatus for supplying a coolant to a closed fluid circuit, preferably for an exhaust gas cooler of an internal combustion engine of a motor vehicle, comprising a connecting stub, wherein the connecting stub is designed for insertion into a coolant connection, wherein a flow-directing device, which is of projection-like design, for the coolant is integrated in the interior of the connecting stub.

Apparatus for supplying a coolant to a heat exchanger, preferably for an exhaust gas cooler of an internal combustion engine of a motor vehicle

A device for the exchange of heat between a first and a second medium with pairs of trays stacked one on top of the other in a stacking direction is provided, wherein a first flow chamber that can be flowed through by a first medium is provided between the two trays of at least one pair of trays or several pairs of trays and a second flow chamber that can be flowed through by a second medium is provided between two pairs of trays adjacent to one another, wherein the first flow chamber has first flow path with flow path sections that can be flowed through consecutively in opposite directions for the first medium, which are separated from one another by a division wall arranged between the at least two trays of the at least one pair of trays, and wherein the second flow chamber has a second flow path for the second medium.

Device for the exchange of heat and motor vehicle

An exhaust-gas cooler for a motor vehicle is provided that includes a flow path which can be traversed by exhaust gas of an internal combustion engine and which has an inlet region and an outlet region for the exhaust gas, a housing which surrounds the flow path and which has at least one inlet and at least one outlet for a liquid coolant of a coolant circuit, wherein the coolant can flow around the flow path in order to cool the exhaust gas, and wherein the coolant circuit is formed as a main cooling circuit of the internal combustion engine of the motor vehicle, wherein the exhaust-gas cooler is arranged in the main cooling circuit in series with the internal combustion engine.
