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

A sealing ring assembly for connection of an exhaust gas cooler to a coolant line may include a carrier ring composed of a plastic, a sealing ring composed of a sealing material connected to the carrier ring; and a heat protection element connected to the carrier ring and surrounding the carrier ring on a radial outer side defining an air gap therebetween.

Sealing ring assembly

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.
