Definitions

  • the described subject matter relates generally to heat exchangers, and more specifically to heat exchangers for use with in various refrigerant systems.
  • the present invention provides a heat exchanger as claimed in claim 1.
  • FIG. 1 depicts crossflow heat exchanger 10 with various portions cut away to illustrate the general location of certain internal features.
  • FIG. 1 also shows first fluid 12, inlet port 14, housing 16, inlet chamber 18, refrigerant passages 20, first/longitudinal axis 22, second incoming fluid 24, air passages 26, second/transverse axis 28, third/no-flow axis 29, outlet chamber 30, and first outlet port 32.
  • Heat exchanger 10 is described with reference to an example evaporator-type heat exchanger for an aircraft.
  • the evaporator can be configured as part of a vapor-cycle air management system (not shown).
  • a vapor-cycle air management system not shown.
  • crossflow heat exchanger 10 shown here is provided for illustrative purposes, and the described subject matter can be readily adapted to other uses.
  • the described subject matter can be adapted to many other heat exchanger configurations in which flow rates of each fluid can be suitably managed.
  • a second non-limiting example embodiment of a counterflow heat exchanger is shown in FIG. 4 .
  • First incoming fluid 12 is received into inlet port 14 formed in housing 16.
  • First incoming fluid 12 can be, for example, a refrigerant having previously been passed through an expansion valve (not shown).
  • Inlet chamber 18 is disposed adjacent to an upstream side of one or more refrigerant passages 20 extending along first or longitudinal axis 22.
  • second incoming fluid 24 e.g., air
  • Air passages 26 can be substantially perpendicular to refrigerant passages 20 and can extend along second or transverse axis 28.
  • parting plates can be stacked along third or no-flow axis 29 to define first and second flow spaces (best shown in FIGS. 2 and 3 ).
  • First flow spaces can provide communication between inlet port 14 and outlet port 32 via refrigerant passages 20, while second flow spaces can provide communication along air passages 26.
  • multiple layers of refrigerant passages 20 and air passages 26 are stacked in alternating first and second flow spaces along third/no-flow axis 29.
  • first incoming fluid 12 is heated and vaporized as it passes through inlet chamber 18, refrigerant passages 20, and outlet chamber 30.
  • First outgoing fluid 36 which in this example is vaporized refrigerant, is then discharged from outlet port 32 spaced longitudinally apart from inlet chamber 14.
  • the heat of vaporization chills adjacent/alternating air passages 26 so that second outgoing fluid 34 has a lower temperature than second incoming fluid 24.
  • first incoming fluid 12 e.g., liquid/vapor phase refrigerant
  • first flow space(s) can be metered before entering refrigerant passages 20 in the first flow space(s).
  • a plurality of metering plates can be disposed across an upstream end of at least one of these first flow spaces.
  • each of the plurality of metering plates can include at least one metering aperture providing fluid communication between the first inlet port and the at least one first flow space.
  • the metering plate(s) can take the form of one or more closure bars or other equivalent structure metallurgically bonded to the internal features of the heat exchanger.
  • FIG. 2 shows a portion of example crossflow heat exchanger 10 taken across line 2-2 of FIG. 1 .
  • FIG. 2 also includes inlet chamber 18, refrigerant passages 20, first/longitudinal axis 22, air passages 26, second/transverse axis 28, third/no-flow axis 29, parting plates 44, first flow spaces 46, second flow spaces 48, first fins 50, upstream refrigerant passage ends 52, first closure bar 54, metering apertures 56, metering plates 60, and second fins 62.
  • a plurality of parting plates 44 are stacked along third/no-flow axis 29 of heat exchanger such that pairs of adjacent parting plates 44 define alternating first flow spaces 46 and second flow spaces 48, therebetween. Portions of first closure bars 56 are cut away to show first flow spaces 46 between parting plates 44, as well as a first plurality of fins 50 disposed in each first flow space 46.
  • First fins 50 form first fluid passages extending along first/longitudinal axis 22. In the evaporator example, the first fluid passages correspond to refrigerant passages 20.
  • Inlet chamber 18 is disposed adjacent to respective upstream ends 52 of each refrigerant passage 20. In the view of FIG. 2 , inlet chamber 18 extends outward from the page.
  • a plurality of first closure bars 54 are disposed along a first edge of first flow space 46 between inlet chamber 18 and upstream refrigerant passage ends 52.
  • One or more metering apertures 56 can be formed (e.g., by machining) through each first closure bar 54, effectively creating a plurality of metering plates 60 disposed in or over an upstream portion of upstream refrigerant passage ends 52.
  • Metering plates 60 either individually or in the form of first closure bar(s) 54, provide fluid communication between inlet chamber 18 and each refrigerant passage 20.
  • First closure bars 54, and/or individual metering plates 60 can be brazed or otherwise metallurgically bonded to adjacent parting plates 44 defining each first flow space 46.
  • First closure bars 54 and/or individual metering plates 60 can be assembled directly to a heat exchanger plate-and-fin subassembly such as the subassembly shown in FIG. 3 .
  • Metering apertures 56 can thus be more closely aligned with each fluid passage (e.g., refrigerant passages 20). It also allows inlet chamber 18 to be an open inlet chamber or header common to multiple refrigerant passages 20.
  • This and other related heat exchanger configurations eliminate the need for a separate distributor tube. In certain embodiments, this reduces the required number of individual fluid headers for each refrigerant passage, potentially reducing weight and manufacturing complexity. Manufacturing variation, tolerance stackup, and assembly errors all increase the occurrence of the misalignment of feedholes formed in the distributor tube relative to individual headers for each refrigerant passage.
  • Metering apertures 56 can be individually configured to control the pressure and resulting flow rate of first incoming fluid 12 (shown in FIG. 1 ) through each refrigerant passage 20.
  • one or more metering apertures 56 are cylindrical or frustoconical.
  • a cross-section of each metering aperture 56 can also be tailored to local or global flow and pressure parameters.
  • each metering aperture 56 can also vary according to its location.
  • the size, shape, and/or cross-sectional area of each aperture can be configured so as to provide a substantially equivalent pressure drop through each of the refrigerant passages 20 between inlet chamber 18 and outlet chamber 30 (shown in FIG. 1 ).
  • the size, shape and/or cross-sectional area of each metering aperture 56 can be made to vary according to its position along at least one of second/transverse axis 28 and third/no-flow axis 29.

  • a second plurality of fins 62 can be disposed in each second flow space 48 to form first fluid passages extending along first/longitudinal axis 22.
  • the second plurality of fins 62 can be disposed transversely to the first plurality of fins 50.
  • FIG. 3 shows plate-and-fin subassembly 110 for a heat exchanger such as an evaporator.
  • FIG. 3 also includes first fluid passages 120, first/longitudinal axis 122, second fluid passages 126, second/transverse axis 128, third/no-flow axis 129, parting plates 144A, 144B, 144C, first flow space 146, second flow space 148, first fins 150, first closure bar 154, metering apertures 156, metering plates 160, second fins 162, first edges 166A, 166B, second closure bar 168, and second edges 170A, 170B.
  • First parting plate 144A, second parting plate 144B, and third parting plate 144C are generally parallel to one another and spaced apart along third/no-flow axis 129.
  • First plurality of fins 150 are disposed in first flow space 146 between first and second parting plates 144A, 144B, defining a plurality of first fluid passages 120 extending along first/longitudinal axis 122.
  • Second plurality of fins 162 can be disposed in second flow space 148 between second and third parting plates 144B, 144C.

  • first closure bar 154 is disposed along first edges 166A, 166B of first flow space 146 between first and second parting plates 144A, 144B.
  • First closure bar 154 can include a plurality of metering apertures 156 in communication with first flow space 146 between adjacent ones of fins 150. This forms effective metering plates 160 disposed at one end of each first fluid passage 120.
  • first closure bar 154 and/or individual metering plates 160 are metallurgically bonded to first and second parting plates 144A, 144B.
  • second closure bar 168 can be arranged transversely to first closure bar 154 along second edges 170A, 170B of first flow space 146. Second closure bar 168 can be free of any metering apertures to prevent leakage or intermingling of fluids passing separately through first and second flow spaces 146, 148. A longitudinal axis of second closure bar 168 can thus be arranged parallel to the first plurality of fins 150.
  • FIG. 4 shows an alternative embodiment which includes counterflow heat exchanger 210.
  • Various portions of counterflow heat exchanger 210 are cut away in FIG. 4 to illustrate the general location of certain internal features. Similar to FIG. 1 , which shows an example crossflow heat exchanger 10, counterflow heat exchanger 210 can also be configured as an evaporator-type heat exchanger. However, counterflow heat exchanger 210 is provided for illustrative purposes, and the described subject matter can be readily adapted to other uses.
  • First incoming fluid 212 for example, a liquid/vapor phase refrigerant mixture, can be received into first inlet port 214A formed in housing 216.
  • Inlet chamber 218A is disposed adjacent to an upstream side of one or more first fluid passages 220, with each passage extending along first/longitudinal axis 222.
  • First fluid 212 then enters outlet chamber 230, where it is discharged (as first outgoing fluid 236) from first outlet port 232A longitudinally spaced apart from first inlet port 214A.
  • Second incoming fluid 224 enters via second inlet port 214B, then flows through housing 216 before exiting from second outlet chamber 230B.
  • Second inlet port 214B is also longitudinally spaced apart from second outlet port 232B.
  • second inlet port 214B can be disposed at the same longitudinal end of heat exchanger 210 as first outlet port 232A, while first inlet port 214A can be disposed at the same longitudinal end of heat exchanger 210 as second outlet port 232B.
  • heat exchanger 210 can be further adapted to a coflow relationship in which fluid inlets 214A, 214B are disposed at the same longitudinal end, and are longitudinally spaced apart from outlet ports 232A, 232B.
  • Second fluid 224 flows through heat exchanger 210 via a plurality of longitudinal second fluid passages 226 in heat transfer relationship with the one or more first fluid passages 220.
  • Multiple layers of first fluid passages 220 and second fluid passages 226 can be stacked in an alternating manner between adjacent parting plates along third/no-flow axis 229.
  • passages 226 can be arranged in a serpentine manner through each layer so that second fluid 224 flows back and forth along first axis 222 before exiting via second outlet port 232B. This is best seen in FIG. 5 .
