Definitions

  • heat exchangers In the aviation engineering, heat exchangers have a fundamental role in the thermal management of various components in the aircraft to ensure that they operate within their designs operating ranges.
  • Heat exchangers may be used to increase or decrease the temperature of fuel during a flight to increase the efficiency of fuel use within the aircraft engines.
  • Such heat exchangers are known in the art.
  • US2016195342 describes a plate fin heat exchanger having a plurality of finned cold layers configured to conduct a first fluid, and a plurality of finned warm layers configured to conduct a second fluid.
  • a first portion of fins of at least one finned warm layer of the plurality of finned warm layers includes a plurality of aligned peaks and valleys defining a wave configuration for each fin of the first portion of fins.
  • heat exchangers in the aircraft should comply with the constructional requirements of the aircraft, e.g. installation volume, pressure drop, heat duty. Further, many aircraft have strict weight and size requirements and it is a challenge to provide a relatively lightweight and space efficient heat exchanger that is capable of providing the required cooling to the components of the aircraft. Furthermore, traditional heat exchangers that are exposed to incoming air may also have a negative effect on the amount of drag on the aircraft.
  • a heat exchanger comprising: a housing comprising: an inlet at a proximal end for receiving a first fluid; and an outlet, downstream of the inlet at the distal end of the housing, through which the fluid is configured to exit the housing; and a plurality of heat exchanger cores within the housing, wherein the plurality of heat exchanger cores meet at a junction and diverge [from each other] towards one of the inlet or the outlet of the housing, wherein the plurality of heat exchanger cores comprise one or more first flow paths through which the first fluid can pass through the heat exchanger cores, in use.
  • the housing may comprise a substantially square-shaped cross section.
  • the housing may be substantially cuboid shaped with an opening at a proximal end and an opening at the distal end.
  • each of the plurality of heat exchanger cores comprises a core inlet for receiving a second fluid and a core outlet through which the second flow is configured to exit the heat exchanger core.
  • the heat exchanger core comprises a finned tube arrangement. In another example, the heat exchanger core comprises a plate-fin arrangement.
  • the heat exchanger core may comprise a plurality of layers.
  • the heat exchanger comprises one or more aerofoils configured to guide the flow of the first fluid.
  • the heat exchanger cores diverge from each other towards the inlet of the housing. In another example, the heat exchanger cores diverge from each other towards the outlet of the housing.
  • the plurality of heat exchanger cores comprises two heat exchanger cores.
  • an aircraft comprising the heat exchanger as described above.
  • the provision of a heat exchanger with diverging heat exchanger cores reduces the pressure drop of a first fluid flowing through the heat exchanger, whilst still providing a high level of heat transfer. Reducing the pressure drop results in a reduction of drag on the aircraft.
  • the heat exchanger may be located within ductwork within an aircraft (with a vent to the air) or alternative coupled to an outer skin of the aircraft.
  • the housing may comprise a substantially square-shaped cross section.
  • the housing may be substantially cuboid shaped with an opening at a proximal end and an opening at the distal end.
  • a length of the heat exchanger is approximately four times the length of a width of the heat exchanger.
  • the length of the heat exchanger is the distance between the distal end and proximal end of the heat exchanger along the longitudinal axis of the heat exchanger.
  • the width of the heat exchanger is the distance between walls of the housing in a direction perpendicular to the longitudinal axis of the housing.
  • each of the plurality of heat exchanger cores comprises a core inlet for receiving a second fluid and a core outlet through which the second flow is configured to exit the heat exchanger core.
  • the core inlet of the heat exchanger core is arranged towards the distal end of the housing. In another example, the core inlet of the heat exchanger is arranged towards the proximal end of the housing. In one example, the core inlet of the heat exchanger is arranged at the junction of the heat exchanger cores.
  • the heat exchanger core is arranged in a counterflow arrangement with respect to the first fluid.
  • the heat exchanger cores may diverge from each other at an angle of between 60 to 160 degrees.
  • the heat exchanger core may comprise a plurality of layers.
  • the heat exchanger comprises one or more aerofoils configured to guide the flow of the first fluid.
  • the heat exchanger cores diverge from each other towards the inlet of the housing. In another example, the heat exchanger cores diverge from each other towards the outlet of the housing.
  • the weight of the heat exchanger is between 9kg to 12kg. This is compared with a weight of 25kg to 30kg for a traditional heat exchanger with a similar heat transfer performance.
  • a heat exchanger with an inclined heat exchanger core that achieves a similar heat transfer performance would weigh approximately 18kg to 21kg.
  • the plurality of heat exchanger cores comprises two heat exchanger cores.
  • Figure 1 shows an example of an aircraft 100 having fuselage 102.
  • Aircraft 100 are well-known in the art and further details of the aircraft have not been provided here.
  • the aircraft comprises a high-altitude long endurance (HALE) unmanned aircraft.
  • HALE aircraft typically have long wingspans and low drag to improve their ability to operate efficiently for weeks or months at altitudes in excess of 15km.
  • HALE aircraft include one or more payloads comprising electronic components, such as sensors that require thermal management.
  • FIG. 2 shows an example of a housing 104 of a heat exchanger.
  • the housing 104 comprises walls 106 configured to provide an enclosure to house a plurality of heat exchanger cores, which will be discussed in more detail below.
  • the enclosure may be open at opposite ends, as will be discussed in more detail below.
  • the housing 104 is shaped so as to be relatively compact, whilst still providing sufficient space for the heat exchanger to be effective.
  • the housing 104 has a length along the longitudinal axis, A-A, of between 0.5m and 1.5m, more preferably 0.8m to 1.2m, more preferably 1m.
  • FIG. 3 shows an example of a traditional cuboid arrangement of a heat exchanger that is not within the scope of this invention.
  • the heat exchanger comprises a core 114 formed of alternating layers 112a, 112b.
  • the alternating layers comprise alternating layers of first fluid paths 112a and second fluid paths 112b.
  • the wall 106 of the housing 104 comprises an aperture through which the second fluid can enter into the core inlet 126.
  • the second fluid would still be isolated from the first fluid as the second fluid would enter directly into a conduit or pipe of the heat exchanger core 122 that is isolated from the first fluid.
  • the first fluid flow enters the heat exchanger 120 via the inlet 108 in the direction represented by arrow F, i.e. substantially parallel to the longitudinal axis A-A of the housing 104.
  • the first fluid then passes through one or more first flow paths of the heat exchanger cores 122 before exiting the housing 104 at the outlet 110.
  • the first fluid flow exits the heat exchanger 120 in the direction indicated by arrow G in Figure 4 .
  • FIG. 5 shows a cross-sectional view of the heat exchanger 120.
  • the heat exchanger cores 122 may have the same shape but are handed about the longitudinal axis A-A of the housing.
  • the junction 124 at which the heat exchanger cores 122 meet may be on the longitudinal axis A-A of the housing. That is to say that the junction may be on a central line, when viewed from above, of the housing 104.
  • the junction 124 may be spaced from the inlet 108 of the housing 104. In one example, the junction 124 spaced at approximately half the width of the housing 104 from the inlet.
  • Figure 5 also shows a width J, which is the dimension perpendicular to the longitudinal axis A-A at the core inlet 126.
  • the heat exchanger cores 122 are configured to diverge at an angle denoted by ⁇ .
  • a key design constraint of the heat exchanger 122 is to keep the external length L and the width J to a minimum for a specific heat duty/pressure drop. This allows the angle ⁇ to be designed to be sufficiently high, so fewer or no flow guiding vanes 130 are required to guide the first fluid flow through the heat exchanger 120. Providing fewer flow guiding vanes 130 reduces the weight of the heat exchanger 120 and makes the design of the heat exchanger 120 easier.
  • the diverging heat exchanger cores 122 maximises the frontal area for the first fluid compared with other arrangements of heat exchangers cores. This leads to a lower pressure drop on the first fluid side and/or allows to use more heat transfer efficient geometries.
  • This arrangement means that the heat exchanger 120 can employ more efficient (heat transfer wise) geometries for the first fluid exchanger side (e.g. the inlet 108 of the housing 104).
  • the geometry of the heat exchanger core 122 is as follows: 0.05 x ⁇ J ⁇ 0.35 x 0.8 y ⁇ L ⁇ 1.2 y
  • the sizes of other components (such as headers) within the heat exchanger 120 should be kept to a minimum to keep the weight in the heat exchanger 120 down.
  • the arrangement of the diverging heat exchanger cores 122 provides minimises the first fluid pressure drop through reducing the local Reynolds number inside the heat exchanger 120.
  • the heat exchanger 120 comprises two heat exchanger cores 122, but more than two heat exchanger cores 122 may be used in practice.
  • the wall 106 of the housing 104 comprises an aperture through which the second fluid can enter the core inlet 126.
  • the second fluid would still be isolated from the first fluid as the second fluid would enter directly into a conduit or pipe of the heat exchanger core 122 that is isolated from the first fluid.
  • An additional aperture may be present in the walls 106 of the housing 104 for the core outlet 128 to allow the second fluid to exit the heat exchanger 120.
  • the core inlets 126 are arranged perpendicular to the longitudinal axis A-A of the housing 104 of the heat exchanger 120, but other arrangements are possible. In this example, the core inlets 126 are arranged towards or adjacent to the inlet 108 of the housing 104.
  • the core outlet 128 may be arranged at or adjacent to the junction 124.
  • the core outlet 128 may be arranged to be perpendicular to the longitudinal axis A-A of the housing 104.
  • the core outlet 128 is configured to be perpendicular to the core inlets 126.
  • the core inlets 126 and core outlet 128 may be reversed from those shown in Figure 6 .
  • the second fluid may enter the heat exchanger core 122 at the core inlet 126, which is located at or approximate to the junction 124 and the second fluid then travels through the heat exchanger core 122 towards the core outlet 128, which may be located at or towards the inlet 108 or outlet 110 of the housing 110.
  • the core inlets 126 of each of the heat exchanger cores 122 may be opposite to each other. That is to say that they are arranged on the opposite sides of the housing 104 relative to each other.
  • the core outlets 128 of the heat exchanger cores 122 are arranged adjacent to each other.
  • the first fluid flow enters the heat exchanger 120 via the inlet 108 in the direction represented by arrow F, i.e. substantially parallel to the longitudinal axis A-A of the housing 104.
  • the first fluid then passes through one or more first flow paths of the heat exchanger cores 122 before exiting the housing 104 at the outlet 110.
  • the first fluid flow exits the heat exchanger 120 in the direction indicated by arrow G in Figure 6 .
  • a second fluid enters the heat exchanger 120 via core inlets 126.
  • the second fluid may enter the heat exchange cores 122 in the direction indicated by arrows H in Figure 6 .
  • the second fluid then travels within the heat exchanger core 122 and exits the heat exchanger core 122 at the core outlet 128.
  • the second fluid exits the heat exchanger cores 122 in the direction indicated by arrow I.
  • the core inlets 126 are shown substantially at or adjacent to the inlet 110 of the housing 104. In other words, the core inlets 126 may be located at or adjacent to the proximal end of the housing 104.
  • the first fluid is air or another compressible fluid (gas).
  • the second fluid may be an incompressible fluid, i.e. liquid such as water or oil.
  • the heat exchanger cores 122 may comprise a finned tube arrangement.
  • Figures 7A and 7B show an example of part of heat exchanger core 122 in the form of a finned tube.
  • the first fluid travels in the direction indicated by arrow M through the heat exchanger core 122.
  • the first fluid travels through one or more first fluid paths through the heat exchanger core 122.
  • the first fluid path may be defined by a plurality of fins 134.
  • the second fluid travels within the heat exchanger core 122 in conduits 132.
  • the fins 134 are thermally coupled to the conduits 132.
  • the heat exchanger cores 122 comprise a plate fin arrangement.
  • Plate fin heat exchangers comprise a greater density than tube fin arrangements owing to their unique geometry which creates a greater surface area for heat transfer to take place. Therefore, plate fin heat exchangers can be made both smaller and more lightweight for a specified heat load or alternatively can dissipate a higher heat load without increasing in size and/or weight when compared to conventional tube fin heat exchangers.
  • Figures 8A and 8B show an example of part of a heat exchanger core 122 in the form of a plate fin arrangement. In this example, there are alternating layers of first fluid paths and second fluid paths. The first fluid may travel in a direction represented by arrow O and the second fluid may travel in a direction represented by arrow P.
  • Figure 8B shows an example of a cross-section through one of the fluid paths.
  • Plate fin heat exchangers may also be manufactured using additive manufacturing techniques, for example selective laser melting, selective laser sintering or directed energy deposition. Such manufacturing techniques allow complex plate fin heat exchanger geometries to be manufactured which are otherwise difficult or impossible with conventional manufacturing techniques. As such, plate fin heat exchangers may be manufactured with even greater surface areas than tube fin heat exchangers or conventionally manufactured plate fin heat exchangers thereby allowing the possibility of smaller, more lightweight heat exchangers for a specified heat load or alternatively the ability to dissipate a higher heat load without increasing in size and/or weight.
