Abstract

A heat exchanger includes at least two manifolds which are fluidly connected to one another by multiple tubes, and a porous metal structure which at least partially surrounds the tubes. The heat exchanger has a plate-like form with a front side and a rear side. The metal structure is formed by a multiplicity of sheets which are held in each case between two adjacent tubes and, on at least one of the front and rear sides of the heat exchanger, extend across at least one adjacent tube.

Claims

1. A heat exchanger, comprising:

at least two manifolds;

plural tubes fluidly connecting the manifolds to each other to define a plate-shaped structure with a front side and a rear side, said front side being a foremost part of the heat exchanger and said rear side being a back part of the heat exchanger, wherein the front side is anodized; and

a porous metal structure configured to at least partially surround the tubes and including a plurality of sheets respectively held between two adjacent ones of the tubes and extending at least on one of the front and rear sides across at least one of the adjacent tubes, with the sheets forming a closed facing on the at least one of the front and rear sides of the tubes, wherein each of the sheets has an L-shaped configuration.

2. The heat exchanger of claim 1, wherein each of the sheets extends on the front side across the at least one of the adjacent tubes.

3. The heat exchanger of claim 1, wherein the sheets are made of an aluminum alloy.

4. The heat exchanger of claim 3, wherein the aluminum alloy is foamed.

5. The heat exchanger of claim 1, wherein the tubes are configured as flat tubes.

6. A vehicle, comprising at least one heat exchanger having a plate-shaped configuration with a front side and a rear side, said front side being a foremost part of the heat exchanger and said rear side being a back part of the heat exchanger, said heat exchanger including at least two manifolds, plural tubes fluidly connecting the manifolds to each other, and a porous metal structure configured to at least partially surround the tubes and including a plurality of sheets respectively held between two adjacent ones of the tubes and extending at least on one of the front and rear sides of the heat exchanger across at least one of the adjacent tubes, with the sheets forming a closed facing on the at least one of the front and rear sides of the heat exchanger of the tubes, wherein each of the sheets has an L-shaped configuration.

7. The vehicle of claim 6, wherein the heat exchanger, when installed, enables air to flow against the front side.

8. The vehicle of claim 6, wherein each of the sheets extends on the front side across the at least one of the adjacent tubes.

9. The vehicle of claim 6, wherein the front side of the heat exchanger is anodized.

10. The vehicle of claim 6, wherein the sheets are made of an aluminum alloy.

11. The vehicle of claim 10, wherein the aluminum alloy is foamed.

12. The vehicle of claim 6, wherein the tubes are configured as flat tubes.
