Abstract

A heat exchanger assembly for a motor vehicle includes a heat exchanger formed by additive manufacturing. The heat exchanger includes two end tanks and a plurality of exchanger tubes. The plurality of exchanger tubes extend in a transverse direction relative to a longitudinal direction of the motor vehicle and connects the two end tanks to each other such that fluid is allowed to flow between the two end tanks by the plurality of exchanger tubes. The heat exchanger has a recess formed therein. A first exchanger tube of the plurality of exchanger tubes has at least one change of direction such that the first exchanger tube bypasses the recess at an angle to the transverse direction and runs along a side of the recess.

First claim

What is claimed is:

1. A heat exchanger assembly for a motor vehicle, the heat exchanger assembly comprising:
at least one heat exchanger formed by additive manufacturing and including at least two end tanks and a plurality of exchanger tubes formed therein, the plurality of exchanger tubes extending in a transverse direction relative to a longitudinal direction of the motor vehicle and connecting the at least two end tanks to each other such that fluid is allowed to flow between the at least two end tanks by the plurality of exchanger tubes,
wherein the at least one heat exchanger has a first recess formed therein, wherein a first exchanger tube of the plurality of exchanger tubes has at least one change of direction such that the first exchanger tube bypasses the first recess at an angle to the transverse direction and runs along a side of the first recess.

2. The heat exchanger assembly according to claim 1 , further comprising a vehicle component at least partially received in the first recess.

3. The heat exchanger assembly according to claim 2 , wherein the vehicle component is an engine hood lock.

4. The heat exchanger assembly according to claim 1 , wherein:
the at least one heat exchanger has a second recess formed therein; and
the plurality of exchanger tubes includes a second exchanger tube that has at least one change of direction such that the second exchanger tube bypasses the second recess at an angle to the transverse direction.

5. The heat exchanger assembly according to claim 1 , wherein the first exchanger tube runs up to a second exchanger tube of the plurality of exchanger tubes and merges with the second exchanger tube in an area of the first recess.

6. The heat exchanger assembly according to claim 1 , wherein the first exchanger tube bypasses a second exchanger tube of the plurality of exchanger tubes in the longitudinal direction.

7. The heat exchanger assembly according to claim 6 , wherein the first exchanger tube is located above the second exchanger tube.

8. The heat exchanger assembly according to claim 6 , wherein the second exchanger tube extends continuously in the transverse direction.

9. The heat exchanger assembly according to claim 1 , wherein contours of each of the at least two end tanks and at least one exchanger tube of the plurality of exchanger tubes transition into each other in a curve.

10. The heat exchanger assembly according to claim 1 , wherein the at least one heat exchanger includes at least two heat exchangers which are connected by at least one additively manufactured, thermally insulating connecting element to form a heat exchanger bundle.

11. A heat exchanger assembly for a motor vehicle, the heat exchanger assembly comprising:
at least one heat exchanger formed by additive manufacturing and including two end tanks and a plurality of exchanger tubes, the plurality of exchanger tubes extending in a transverse direction relative to a longitudinal direction of the motor vehicle and connecting the two end tanks to each other such that fluid is allowed to flow between the two end tanks by the plurality of exchanger tubes,
wherein the at least one heat exchanger has a first recess and a second recess formed therein, wherein a first exchanger tube of the plurality of exchanger tubes extends along the transverse direction and has at least one change of direction such that the first exchanger tube bypasses the first recess at a first angle to the transverse direction and runs along a first side of the first recess, and
wherein one end tank of the two end tanks extends along a vertical direction of the motor vehicle and has at least one change of direction such that the one end tank bypasses the second recess at a second angle to the vertical direction and runs along a second side of the second recess.

12. The heat exchanger assembly according to claim 11 , further comprising a vehicle component at least partially received in the first recess.

13. The heat exchanger assembly according to claim 12 , wherein the vehicle component is an engine hood lock.

14. The heat exchanger assembly according to claim 11 , further comprising a vehicle component at least partially received in the second recess.

15. The heat exchanger assembly according to claim 14 , wherein the vehicle component is a bumper.

16. The heat exchanger assembly according to claim 11 , wherein the first exchanger tube runs up to a second exchanger tube of the plurality of exchanger tubes and merges with the second exchanger tube in an area of the first recess.

17. The heat exchanger assembly according to claim 11 , wherein the first exchanger tube bypasses a second exchanger tube of the plurality of exchanger tubes in the longitudinal direction.

18. The heat exchanger assembly according to claim 17 , wherein the first exchanger tube is located above the second exchanger tube.

19. The heat exchanger assembly according to claim 17 , wherein the second exchanger tube extends continuously in the transverse direction.

20. The heat exchanger assembly according to claim 11 , wherein the at least one heat exchanger includes at least two heat exchangers which are connected by at least one additively manufactured, thermally insulating connecting element to form a heat exchanger bundle.
