Abstract

An apparatus and method of forming a heat exchanger including a thermally compliant material and geometry with a core having a first set of flow passages and a second set of flow passages passing through the core. A first manifold of high temperature and strength material defines a fluid inlet for the first set of flow passages and a second manifold of high temperature and strength material defines a fluid inlet for the second set of flow passages. At least one of the first and second manifolds can include an in-situ compliant portion to provide for compliance during thermal expansion of the heat exchanger.

First claim

What is claimed is:

1. A heat exchanger, comprising:
a core having a first set of flow passages;
a first manifold having a first wall and a first fluid inlet, with the first fluid inlet in fluid communication with the first set of flow passages;
a compliant portion forming at least part of the first wall to provide compliance for the first wall; and
a second set of flow passages in the core and a second manifold having a second wall with a second compliant portion and in fluid communication with the second set of flow passages;
wherein the first wall and the second wall form a shared wall adjoining the first and second manifolds and wherein the compliant portion forms at least a portion of the shared wall.

2. The heat exchanger of claim 1 wherein a sizing of ridges in the compliant portion in the first wall is tunable with respect to sizing of ridges of the second compliant portion.

3. The heat exchanger of claim 1 wherein the first manifold further includes a third compliant portion.

4. The heat exchanger of claim 1 wherein an outer housing surrounds the core and the first manifold operably couples to the outer housing.

5. The heat exchanger of claim 4 wherein the outer housing further comprises a housing compliant portion.

6. The heat exchanger of claim 1 wherein the core and the first manifold with the compliant portion are either an integral body or a unitary body.

7. The heat exchanger of claim 6 wherein the core is aluminum and the first manifold is nickel, nickel-cobalt, or a nickel alloy.

8. The heat exchanger of claim 1 , further comprising a mounting flange distally located from the compliant portion and wherein the mounting flange is configured to mount to a portion of an aircraft.

9. A heat exchanger, comprising:
a core having a first set of flow passages and a second set of flow passages;
a first manifold having a first wall and a first fluid inlet, with the first fluid inlet in fluid communication with the first set of flow passages;
a compliant portion forming at least a portion of the first wall to provide compliance for the first wall;
a second manifold having a second wall and a second fluid inlet, with the second fluid inlet in fluid communication with the second set of flow passages;
a second compliant portion forming at least a portion of the second wall; and
a third compliant portion forming at least a portion of the second wall.

10. The heat exchanger of claim 9 wherein a sizing of ridges in the compliant portion in the first wall is tunable with respect to sizing of ridges of the second compliant portion.

11. The heat exchanger of claim 9 wherein the first wall and the second wall form a shared wall, adjoining the first and second manifolds.

12. The heat exchanger of claim 11 wherein the compliant portion forms at least a portion of the shared wall.

13. The heat exchanger of claim 9 wherein an outer housing surrounds the core and the first manifold operably couples to the outer housing.

14. The heat exchanger of claim 13 wherein the outer housing further comprises a housing compliant portion.

15. The heat exchanger of claim 9 wherein the core and the first manifold with the compliant portion are either an integral body or a unitary body.

16. The heat exchanger of claim 15 wherein the core is aluminum and the first manifold is nickel, nickel-cobalt, or a nickel alloy.

17. The heat exchanger of claim 9 , further comprising a mounting flange distally located from the compliant portion and wherein the mounting flange is configured to mount to a portion of an aircraft.
