Abstract

Die Erfindung betrifft einen Wärmeübertrager, insbesondere Abgaskühler, mit einteilig oder aus zwei schalenartigen Scheiben gebildeten Rohren, die einen ersten und einen zweiten Fluidkanal bilden, wobei die jeweiligen Fluidkanäle benachbart zueinander angeordnet sind, wobei der erste Fluidkanal an zumindest einem seiner Enden offen ausgebildet ist zum Ein- und/oder Ausströmen des ersten Fluids, wobei die Rohre an den Enden durch eine Abstufung nach innen oder außen so ausgebildet sind, dass die zweiten Fluidkanäle stirnseitig verschlossen sind, wobei die Abstufung in den Eckbereichen des Rohres eine größere Ausdehnung T in Rohrlängsrichtung hat, als zwischen den Eckbereichen.

Figure imgaf001
The invention relates to a heat exchanger, in particular exhaust gas cooler, with one or two shell-like discs forming tubes, which form a first and a second fluid channel, wherein the respective fluid channels are adjacent to each other, wherein the first fluid channel is open at at least one of its ends Inlet and / or outflow of the first fluid, wherein the tubes are formed at the ends by a gradation inwardly or outwardly so that the second fluid channels are closed at the end, wherein the gradation in the corner regions of the tube has a greater extension T in the tube longitudinal direction , as between the corner areas.
