Abstract

A heat exchanger for a motor vehicle, with a housing with a first housing side and with a second housing side opposite to the first housing side, and with an inner housing wall and with an outer housing wall. The tubes, through which a gas can flow, are disposed in the housing. The tubes each of which has a first tube end and a second tube end, opposite to the first tube end, and with a first tube sheet disposed in the area of the first housing side. A first tube sheet has a number of first through-openings, through which the first tube ends extend, and a second tube sheet disposed in the area of the second housing side that has a number of second through-openings through which the second tube ends extend. The first tube sheet forms a first plane and the second tube sheet forms a second plane.

First claim

What is claimed is:

1 . A heat exchanger comprising:
a housing with a first housing side and a second housing side opposite to the first housing side and with an inner housing wall and an outer housing wall; tubes through which a gas is adapted to flow, the tubes being arranged in the housing, the tubes each have a first tube end and a second tube end opposite to the first tube end; a first tube sheet arranged in an area of the first housing side, the first tube sheet having a plurality of first through-openings through which the first tube ends extend; and a second tube sheet arranged in an area of the second housing side, the second tube sheet having a plurality of second through-openings through which the second tube ends, wherein the first tube sheet forms a first plane and the second tube sheet forms a second plane, wherein the first tube sheet has a first circumferential edge raised at a first angle from the first plane and the second tube sheet has a circumferential second edge raised at a second angle from the second plane, and wherein the first edge in the area of the first housing side is connected to the inner housing wall or in the area of the first housing side to the outer housing wall and/or wherein the second edge in the area of the second housing side is connected to the inner housing wall or in the area of the second housing side to the outer housing wall.

2 . The heat exchanger according to claim 1 , wherein the first edge has a first contact side and a second contact side opposite to the first contact side, wherein the first contact side in the area of the first housing side is connected to the inner housing wall or the second contact side in the area of the first housing side is connected to the outer housing wall.

3 . The heat exchanger according to claim 1 , wherein the second edge has a first contact area and a second contact area opposite to the first contact area, wherein the first contact area in the area of the second housing side is connected to the inner housing wall or the second contact area in the area of the second housing side is connected to the outer housing wall.

4 . The heat exchanger according to claim 1 , wherein the tubes are arranged substantially lying parallel next to one another in the longitudinal direction such that gaps, through which a coolant is adapted to flow, are formed between the tubes.

5 . The heat exchanger according to claim 1 , wherein the first contact side and/or the second contact side and/or the first contact area and/or the second contact area are connected to the inner housing wall and/or the outer housing wall by soldering or welding.

6 . The heat exchanger according to claim 1 , wherein the first contact side and/or the second contact side and/or the first contact area and/or the second contact area are connected to the inner housing wall and/or the outer housing wall substantially by material bonding.

7 . The heat exchanger according to claim 1 , wherein the first tube ends in the area of the first through-openings are connected to the first tube sheet by soldering or welding and the second tube ends in the area of the second through-openings are connected to the second tube sheet by soldering or welding.

8 . The heat exchanger according to claim 1 , wherein the first through-openings and/or the second through-openings each have passages through which the first tube ends and/or the second tube ends extend.

9 . The heat exchanger according to claim 1 , wherein the housing has an inlet opening for a coolant supply and/or an outlet opening for coolant removal.

10 . The heat exchanger according to claim 1 , wherein the tubes are formed as flat tubes, and/or turbulence inserts and/or spacers and/or corrugated fins are arranged between the tubes, and/or wherein the tubes have a substantially smooth surface and/or a substantially circular cross section.

11 . The heat exchanger according to claim 1 , wherein the first tube sheet and/or the second tube sheet are produced in a deep-drawing process.

12 . The heat exchanger according to claim 1 , wherein a bypass channel is located in an area of the housing.

13 . The heat exchanger according to claim 1 , wherein the heat exchanger is an exhaust gas heat exchanger or a charge air cooler for a motor vehicle.
