Definitions

  • the disclosure is directed generally to heat exchangers, and more specifically to cores and mounts for heat exchangers.
  • Mounts are used to connect the heat exchanger to other components or the aircraft directly. There are loads applied from the connecting body to the heat exchanger creating a stress at the connection between the mount pad and the core.
  • the mount is brazed and/or welded to the core and the load is transmitted through the joint and internal core components, at roughly a 45° angle outward from the joint.
  • An embodiment of a heat exchanger core includes a plurality of walls defining a plurality of layers in at least one heat exchange relationship. At least one of the layers of the core having a first load-bearing portion aligned with and adjacent to a first mount location on a perimeter of the core, and a first non-load-bearing portion distal from the non-load-bearing portion. A topology of the first load-bearing portion has a load bearing capacity greater than load bearing capacity of the non-load-bearing portion.
  • An embodiment of a heat exchanger assembly includes a mount for supporting a heat exchanger in a system and a heat exchanger core.
  • the heat exchanger core includes a plurality of walls defining a plurality of layers in at least one heat exchange relationship. At least one of the layers of the core has a first load-bearing portion aligned with and adjacent to a first mount location on a perimeter of the core, and a first non-load-bearing portion distal from the non-load-bearing portion.
  • a topology of the first load-bearing portion has a load bearing capacity greater than a load bearing capacity of the non-load-bearing portion.
  • An embodiment of a method of making a heat exchanger includes forming a housing for a heat exchanger core and additively manufacturing a heat exchanger core.
  • the housing including a first mount portion.
  • Additively manufacturing the heat exchanger core includes forming a first load-bearing region in connection with the joint/mount, and forming a first non-load bearing region outward of the non-load bearing region.
  • FIG. 1 includes multiple views of an example heat exchanger.
  • FIG. 2A shows a conventional core geometry of a plate-and-fin heat exchanger.
  • FIG. 2B is a magnified view of a portion of FIG. 2A .
  • FIG. 3A shows an updated example core geometry for a plate-and-fin heat exchanger according to the disclosure.
  • FIG. 3B is a magnified view of a portion of FIG. 3A .
  • FIG. 4 is a conventional mounting arrangement for a shell-and-tube core of a heat exchanger.
  • FIG. 5 shows an example mounting arrangement for a core of a shell-and-tube heat exchanger according to the disclosure.
  • FIG. 6 shows a strengthened core topology and mounting arrangement for a second heat exchanger embodiment.
  • FIGS. 7A and 7B depict a third heat exchanger embodiment with mounts integrally formed with one or more manifolds.
  • Integrally building a mount with the core using additive manufacturing or castings removes the need to braze, machine, and/or weld the mount to a pad. This can increase the effective contact area between the mount and the core, allowing the load to be distributed better through the core components. Additionally, the structure can be optimized for weight without having to maintain unnecessary material needed to connect the mount to the heat exchanger. Assembly weight, installation time, installation space, and component count may all be reduced.
  • FIG. 1 shows an example heat exchanger assembly 10 , with first and second views 10 - 1 and 10 - 2 .
  • assembly 10 includes core 12 and one or more manifolds 14 A, 14 B, 14 C meeting at respective manifold/core interfaces 16 A, 16 B, 16 C.
  • First manifold 14 A and second manifold 14 B are connected to and in fluid communication with core 12 at respective first and second manifold/core interfaces 16 A, 16 B.
  • Core 12 generally receives and places a plurality of mediums (here 20 , 22 ) in at least one heat exchange relationship with one another.
  • core 12 can include structures, walls, tubes, etc. to facilitate a cross-flow, counter-flow, micro-channel, or other hybrid heat exchange relationship.
  • heat exchanger assembly 10 can include a plate-and-fin heat exchanger or any other type of heat exchanger that, generally, consists of alternating layers (e.g., micro-channel heat exchangers). Assembly 10 can also include one or more mount areas (not shown in FIG. 1 ) for supporting heat exchanger assembly 10 in a larger system.
  • first manifold 14 A include a first end 26 A distal from core 12 with at least one port 24 A adapted to receive (or discharge) a first medium of the plurality of mediums (e.g., medium 20 or 22 ).
  • Second end 28 A of first manifold 14 A is joined to core 12 at first manifold/core interface 16 A, and is adapted to transfer first medium 20 or second medium 22 , either to or from a plurality of first heat exchange passages in core 12 .
  • second manifold 14 B includes a first end 26 B and a second end 28 B, the first end distal from core 12 with at least one port 24 B adapted to discharge (or receive) the first medium 20 .
  • Second end 28 B of second manifold 14 B is joined to core 12 at second manifold/core interface 16 B, and is adapted to transfer first medium 20 either to or from a plurality of first heat exchange passages in core 12 .
  • Third manifold 14 C includes first end 26 C and second end 28 C for medium 22 to exit core 12 via port 24 C.
  • core 12 receives first medium 20 flowing in first direction X and second medium 22 of the plurality of mediums flowing in second direction Y at a zero or nonzero angle relative to first direction X.
  • These directions may vary from layer to layer within the core, for example in a counterflow heat exchanger core, versus the cross-flow arrangement shown in FIG. 1 .
  • FIGS. 2A and 2B show a conventional geometry for a plate-and-fin heat exchanger core 12 ′.
  • core 12 ′ includes walls defining a topology of alternating flow layers 30 ′, 32 ′ respectively for first medium 20 and second medium 22 .
  • parting plates 36 ′ separate and define alternating flow layers 30 ′, 32 ′.
  • first fins 38 ′ provide additional heat transfer area for first medium 20 in first flow layers 30 ′.
  • second fins (omitted for clarity) can be provided in second flow layers 32 ′ for providing additional heat transfer area for second medium 22 .
  • FIGS. 2A and 2B In a mount arrangement for a conventional heat exchanger core, such as is shown in FIGS. 2A and 2B , certain parts of core 12 ′, particularly load-bearing portion or portions of layers immediately adjacent to the mount location or joint bear a disproportionate amount of the weight, vibrational, and other loads as compared to other parts more distal from the load-bearing portion. This has traditionally been dealt with, due to manufacturability and cost concerns, by uniformly using thicker plate or fin material throughout individual layers in order to absorb and transmit the loads as shown, while preventing damage to the unit.
  • each layer 30 ′ of conventional core 12 ′ has generally uniform topology though adjacent layers 30 ′ likely differ.
  • Each individual parting plate 36 ′ has a uniform plate thickness T′ across an individual heat transfer layer 30 ′, while each fin 38 ′ has substantially uniform fin thickness F′ and pitch P′ (e.g., spacing between corrugations) across an individual heat transfer layer 30 ′.
  • plates 36 ′ closer to the mount location(s) 18 ′ and/or joint(s) 19 ′ may have a greater thickness than those below.
  • conventional fins 38 ′ in layers close to mount location(s) 18 ′ and/or joint(s) 19 ′ may have a greater fin thickness F′ and/or lesser pitch P′ (corrugations closer together) than those fins 38 ′ in layers below (i.e., distal from) mount location(s) 18 ′.
  • thickness and pitch are conventionally uniform across each individual layer.
  • Conventional layer strengthening thus includes areas of the core outside of the parts nearest to the mount area and thus most responsible for load bearing. These regions are identified outside of dashed line 40 ′ representing approximately a perimeter of the expected or actual load path.
  • dashed line 40 ′ representing approximately a perimeter of the expected or actual load path.
  • the load path extends approximately 45° outward through core 12 ′, but the angle and exact path may vary depending on the types and numbers of attachment points.
  • arrangements like those in FIGS. 2A and 2B unnecessarily add weight, reduce available volume for throughput of the mediums, and can impede conduction of thermal energy through the heat transfer surfaces because non-load-bearing areas of the core are unnecessarily oversized.
  • FIGS. 3A and 3B show an updated example core 112 which, like conventional core 12 ′ in FIGS. 2A and 2B , includes a plurality of walls defining a plurality of alternating layers for placing first and second mediums 120 , 122 in at least one heat exchange relationship.
  • FIGS. 3A and 3B show first layers 130 A, 130 B, 130 C and second layers 132 A, 132 B of core 112 , along with load path 140 .
  • Each of first layers 130 A, 130 B, 130 C has at least one corresponding load-bearing portion 144 A, 144 B, 144 C aligned with, and adjacent to, at least a first mount location 118 and/or joint 119 on a perimeter 142 of core 112 .
  • Perimeter can be defined by, for example, closure bars or end plates 134 .
  • One or more non-load-bearing portions 146 A, 146 B, 146 C of each layer 130 A, 130 B, 130 C can be located distal from load-bearing portion(s) 144 A, 144 B, 144 C.
  • Load-bearing portions of second layers 132 A, 132 B can also be strengthened in a similar manner, but these are omitted for clarity.
  • a topology of the first load-bearing portion 144 A has an overall load bearing capacity greater than a load bearing capacity of the non-load-bearing portion 146 A in the same layer 130 A. That is, at least one layer 130 A of core 112 is locally strengthened by varying one or more aspects of the walls (e.g., plates, fins, tubes, etc.) defining the passages in the load-bearing portion. To save weight and material costs, parts of the layer remain sufficiently thin and/or well-spaced to manage desired medium flows.
  • first layers 130 A, 130 B, 130 C shows one or more variation or adaptation in the respective load bearing portion 144 A, 144 B, 144 C; however, it will be recognized that multiple aspects can be modified in each load-bearing portion(s) of one or more layers.
  • a pitch P 2 of the plurality of corrugated fins 138 in load-bearing portion 144 C is greater than a pitch P 1 of the plurality of corrugated fins 138 in the same layer ( 130 C) in the non-load-bearing portion 146 C.
  • the sheet(s) forming the fins in layer 130 C are further compressed in load-bearing portion 144 C so that each wall or fin is closer to an adjacent one as compared to the spacing in non-load-bearing portion 146 C.
  • This can reduce available flow area locally, but by maintaining or even expanding pitch in non-load-bearing portion 146 C, overall heat transfer and/or pressure drop can be substantially maintained relative to conventional designs.
  • a fin thickness F 1 of the plurality of fins 138 in load-bearing portions 144 A, 144 B is greater than a fin thickness F 2 of the plurality of corrugated fins 138 in the same layer (here 130 A, 130 B) in the respective non-load-bearing portions 146 A, 146 B.
  • the locally thicker material in the load-bearing portion again can absorb and transmit forces, while allowing for thinner fin material elsewhere. This again may reduce local flow to a lesser degree as compared to a conventional approach
  • a thickness T 1 of one or more parting plates 136 separating the plurality of corrugated fins in the first load-bearing portion 144 B is less than a thickness T 2 of the plurality of parting plates in the same layer in non-load-bearing portion 146 B.
  • load path 140 is merely illustrated for simplicity as a dashed line, but should not be read as a precise stepwise difference between the load-bearing and non-load-bearing portions in all cases. Rather, depending on the precise construction of the unit, the mount, and the loads applied thereto, there is somewhat of a gradual transition region on either side of dashed line 140 (and other load paths described herein).
  • the dashed line(s) are therefore merely intended to represent an approximate midpoint of this transition region in order to more clearly and simply delineate the load-bearing and non-load-bearing portions without adding clutter to the figures.
  • a mount portion of the core is integrally formed with at least one of a mount pad and an end plate of the heat exchanger core.
  • FIG. 4 shows a heat exchanger and accompanying mount arrangement
  • FIG. 5 shows the mount includes at least one mount arm integrally supporting at least one element, a tube in this case, of the heat exchanger core. Additional embodiments show the heat exchanger assembly supportable by several mounts integrally formed with one or more manifolds.
  • a conventional mounted heat exchanger assembly 210 includes core 212 , mount bar 215 , mount pad 217 , mount location 218 on core 212 , and joint(s) 219 .
  • mount pad 217 is attached to core 212 at mount location 218 , in particular to multiple tubes 225 in a shell-and-tube arrangement shown herein.
  • Mount pad 217 can be conventionally formed, for example, by machining, extrusion, and/or casting.
  • mount bar 215 is welded, brazed, or otherwise metallurgically joined around joint 219 near a perimeter of mount pad 217 , securing core 212 to one or more support structures (via mount bar 215 ). In this arrangement, loads from the aircraft or other mounting support structures (not shown) create high stress loads at connections 221 between mount pad 217 and tubes 225 in core 212 .
  • FIG. 5 includes assembly 310 with core 312 directly metallurgically joined to the mount by at least one joint 319 , with core 312 adapted for receiving and placing a plurality of mediums in at least one heat exchange relationship.

  • Mount 321 includes at least one clevis leg or bar 323 integrally formed with and supported by at least one tube 325 of heat exchanger core 312 . This allows for a substantially uniform connection between mount bar 315 and core 312 , rather than merely about edges of mount pad 217 in FIG. 4 .
  • FIG. 6 shows an alternate embodiment of heat exchanger assembly 410 for an example shell-and-tube heat exchanger core 412 .
  • Core 412 adapted for receiving and placing a plurality of mediums in at least one heat exchange relationship, includes one or more tubes 425 directly metallurgically joined around mount location 421 by at least one joint such as clevis leg or bar 423 .

  • Mount 421 is also integrally formed with at least one of a mount pad and an end plate (not shown) of heat exchanger core 412 . This allows for a substantially uniform connection between mount bar 415 and core 412 , rather than merely about edges of mount pad (e.g., 217 in FIG. 4 ).
  • Core 412 also includes first load-bearing region 444 in connection with the joint/mount and a first non-load bearing region 446 outward of the non-load bearing region.
  • the heat exchanger core includes a different (stronger) topology in at least one load-bearing region ( 444 ) versus than in a corresponding at least one non-load-bearing region 446 in the same layer.

  • Embodiments of heat exchangers described herein can leverage additive manufacturing or any other manufacturing method or methods (e.g., casting) that allows one to construct continuous, homogeneous transitions between one or more mounts and the core, the manifold, or other assembly components. Continuous, homogeneous transitions between elements within the core can closely tailor load bearing capacity. Additive manufacturing is also useful in reducing mass and/or weight of different elements of the assembly, as well as reducing the number of details and associated assembly time. Further, additive manufacturing allows the mount to be optimized with less constraint on how to connect the mount to the heat exchanger core. The entire connection between the mount and heat exchanger is made by metallurgical bond instead of just welded edges as in the conventional approaches.
