BACKGROUND
[002] In the manufacture of ram air heat exchangers using thermally conductive carbon foam as a thermal management material, metallic and carbon elements may be used in fabrication of the heat exchanger core. The metallic and carbon elements used in fabrication of the heat exchanger core may have different coefficients of thermal expansion (CTE). Therefore, during fabrication, high-temperature vacuum brazing processes may generate thermal stresses within the heat exchanger core during the heat-up and cool-down phases of the brazing process.
82,000-167 (003] Therefore, fabrication processes that address thermal stresses caused by mismatched coefficients of thermal expansion (CTE) in a mixed carbon foam/metallic heat exchanger may be desirable.

DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0015] Referring initially to FIGS. 1-4, an illustrative embodiment of the mixed carbon foam/metallic foam heat exchanger, hereinafter heat exchanger, is generally indicated by reference numeral 1 in FIG. 1. The heat exchanger 1 may include a heat exchanger frame 2 which may be aluminum, for example and without limitation, and may include an upper end plate 3; a lower end plate 4 placed in an opposed relationship with respect to the upper end plate 82,000-167 3; and spaced apart end plates 5 at respective ends of the upper end plate 3 and the lower end plate 4. At each end of the heat exchanger frame 2, carbon foam layers 14 may be exposed through plate slots 6 which separate adjacent side bar members 5 from each other.
[0016] At least one ductile thermal management material layer 10 may be provided in the heat exchanger frame 2. As shown in FIG. 2, the ductile thermal management material layer 10 may be reticulated metal foam such as reticulated aluminum foam, for example and without limitation. In certain applications the fluids in the heat exchanger may require the use of other ductile materials such as copper, copper alloys, stainless steels, nickel alloys, etc. At least one thermally conductive carbon foam layer 14 may be provided in the heat exchanger frame 2 in thermally-conductive contact with at least one ductile thermal management material layer 10. The carbon foam may, in certain applications be replaced by other foams, such as a ceramic. The ductile thermal management material layer 10 and the thermally conductive carbon foam layer 14 may have different coefficients of thermal expansion (CTEs), for example the CTEs of the two materials may differ by a 82,000-167 factor of three or more. As shown in FIG. 2B, in some embodiments each ductile thermal management material layer may be separated from each carbon foam layer 14 by a thermally-conductive fluid barrier 18. Accordingly, the ductile thermal management material layer 10 may be attached to a first surface 18a and the carbon foam layer 14 may be attached to a second surface 18b of the thermally-conductive fluid barrier 18 according to the knowledge of those skilled in the art. The thermally-conductive fluid barrier 18 may be a metal braze foil layer, for example and without limitation.
[0017] As shown in FIGS. 1 and 3, multiple stress relief blind slots 11 may extend into each ductile thermal management material layer 10. The stress relief blind slots 11 may be placed in generally parallel, staggered relationship with respect to each other and may be oriented in generally perpendicular relationship with respect to a longitudinal axis of the ductile thermal management layer 10. Each stress relief slot 11 may or may not extend across the entire thickness of the ductile thermal management material layer 10. As shown in FIGS. 1 and 4, stress relief blind slots 15 may also be provided in the 82,000-167 thermally conductive carbon foam layer 14 and each may or may not extend across the entire thickness of the carbon foam layer 14. The stress relief blind slots 11 and stress relief blind slots 15 may provide stress relief for the heat exchanger 1 during manufacturing and in operation.
Furthermore, the stress relief blind slots 11 and stress relief blind slots 15 may provide control of fluid flow losses through the ductile thermal management material layer 10 and the thermally conductive carbon foam layer 14 ,respectively, in operation of the heat exchanger 1.
Furthermore, the stress relief blind slots 11 and stress relief blind slots 15 may provide control of fluid flow losses through the ductile thermal management material layer 10 and the thermally conductive carbon foam layer 14 ,respectively, in operation of the heat exchanger 1.
[0018] As shown in FIGS. 1 and 4, the ductile thermal management material layers 10 and the thermally conductive carbon foam layers 14 may be arranged in the heat exchanger frame 2 in alternating relationship with respect to each other, with each carbon foam layer 14 sandwiched between a pair of ductile thermal management material layers 10. The heat exchanger frame 2 may include multiple side bar members 7 each of which may extend into a plate slot 6 between the end plates 5 at respective ends of the heat exchanger frame 2. Each side bar member 7 may be generally placed between ductile thermal management material layers 82,000-167 and generally adjacent to a thermally conductive carbon foam layer 14.
[0019] In some applications of the heat exchanger 1, CTE
induced thermal stresses may be a function of length scale.
Therefore, as shown in FIGS. 1 and 4, the thermally conductive carbon foam layers 14 may be segmented in multiple sections and tolerance-fitted together in the heat exchanger frame 2. Segmentation of the carbon foam layers 14 may reduce the total length scale between each element of the carbon foam layers 14 and the metallic portions of the heat exchanger 1 such as the various elements of the heat exchanger frame 2, for example and without limitation, to reduce CTE induced thermal stresses between the carbon foam layers 14 and those metallic portions of the heat exchanger 1 during operation of the heat exchanger 1.
induced thermal stresses may be a function of length scale.
Therefore, as shown in FIGS. 1 and 4, the thermally conductive carbon foam layers 14 may be segmented in multiple sections and tolerance-fitted together in the heat exchanger frame 2. Segmentation of the carbon foam layers 14 may reduce the total length scale between each element of the carbon foam layers 14 and the metallic portions of the heat exchanger 1 such as the various elements of the heat exchanger frame 2, for example and without limitation, to reduce CTE induced thermal stresses between the carbon foam layers 14 and those metallic portions of the heat exchanger 1 during operation of the heat exchanger 1.
[0020] During fabrication of the heat exchanger 1, a vacuum brazing process may be used as is known to those skilled in the art. Accordingly, the ductile thermal management material layers 10 and the thermally conductive carbon foam layers 14, separated by thermally-conductive fluid barriers 18, may be stacked and brazed together during fabrication. It will be appreciated by those 82,000-167 skilled in the art that during the vacuum brazing process, the high thermal stresses resulting from thermal expansion and contraction induced in the heat exchanger frame 2 of the heat exchanger 1 may be absorbed by the ductile thermal management material layers 10. The thermal management material layers 10 may not transfer the thermal stresses from the heat exchanger frame 2 to the thermally conductive carbon foam layers 14. This may prevent the application of excessive thermally induced stress on the carbon foam layers 14.
[0021] In application of the heat exchanger 1, a first slot (not shown) may be placed in fluid communication with the ductile thermal management material layers 10 and a second slot (not shown) may be placed in fluid communication with the thermally conductive carbon foam layers 14. A first fluid (not shown) may be distributed from the first slot through the thermal management material layers 10, and a second fluid (not shown) may be distributed from the second slot through the carbon foam layers 14. Accordingly, heat may be transferred by convection and conduction from the hotter to the cooler of the first fluid and the second fluid through the thermally-82,000-167 conductive fluid barrier 18 (FIG. 2B). The high thermal stresses resulting from thermal expansion induced in the heat exchanger 1 by the hotter of the first fluid and the second fluid may be absorbed by the ductile thermal management material 10. This may prevent the application of excessive thermally induced stress on the carbon foam layers 14. The upper end plate 3, lower end plate 4 and side bar members 5 of the heat exchanger frame 2 may prevent loss of fluid from the heat exchanger 1.
[0022] Referring next to FIG. 5, a flow diagram 500 which illustrates an illustrative embodiment of a mixed carbon foam/metallic foam heat exchanger method is shown.
In block 502, a reticulated metal foam layer is provided.
In block 503, a thermally-conductive fluid barrier is provided in thermally conductive contact with the reticulated metal foam layer. In block 504, a thermally conductive carbon foam layer is provided in thermally-conductive contact with the thermally-conductive fluid barrier. In block 506, a first fluid is distributed through the reticulated metal foam layer. In block 508, a second fluid is distributed through the carbon foam layer.
Heat is transferred from the hotter to the cooler of the 82,000-167 first fluid and the second fluid. The reticulated metal foam layer may absorb stresses which are induced by thermal expansion during transfer of the heat between the fluids, minimizing or eliminating thermal stresses exerted on the carbon foam layer.
