Definitions

  • the present disclosure relates to a heat exchanger.
  • Components using a matrix typically comprise a conduit for providing fluid flow to an inlet of the matrix.
  • the conduit cross-sectional area is less than that of the matrix inlet.
  • the matrix and the conduit are sized such that a flow from the conduit can disperse throughout the entire matrix volume to maximise the contact area. As such, providing a relatively wide conduit with a slow fluid flow allows the flow to disperse evenly.
  • JP 2007-271122 discloses a prior art system according to the preamble of claim 1.
  • FR 1,032,990 discloses prior art tubular heat exchangers.
  • GB 2 078 927 A discloses a prior art heat exchange system.
  • JP 3-238128 discloses a prior art heat exchanger and method.
  • WO 2011/021636 A1 discloses a prior art heat exchanger and refrigeration device with same.
  • the fins may be straight along their length.
  • the fins may be at least partially curved.
  • the fins may be curved along their entire length, or the fins may be straight at an inlet to the conduit and gradually curve to be angled at the exit to the conduit.
  • the fins may be corrugated.
  • the first plurality of fins may be distributed around the entire circumference of the interior surface of the conduit.
  • the fins may be distributed around less than 50% of the circumference of the interior surface of the conduit, for example around 25% of the circumference of the interior surface of the conduit.
  • the second flow passage may extend around the entire circumference of the conduit. Alternatively the second flow passage may extend around less than 50% of the circumference of the conduit.
  • the second flow passage may be circumferentially coterminous with the fins.
  • the conduit may further comprise an exterior surface, wherein the second flow passage is disposed between the interior surface and exterior surface of the conduit.
  • the conduit may comprise a second plurality of fins which project into the second flow passage.
  • the second plurality of fins may be aligned with the first plurality of fins.
  • the second plurality of fins may be extensions of the first plurality of fins.
  • the conduit cross-section may have a maximum diameter of less than 200mm. In certain embodiments, the conduit may have a diameter of between 50mm and 150mm.
  • the conduit may further comprise an outlet, wherein an angle formed between the fins and the longitudinal axis of the conduit at the outlet is between 10° and 45°, for example between 10° and 20°.
  • the heat exchanger cross-section may be annular.
  • the heat exchanger may be an air-liquid heat exchanger.
  • the plurality of fins may project less than 50% of the radial distance between the interior surface and a centre of the conduit, for example between 25% and 50% of the radius of the conduit.
  • the fins may be evenly distributed on the interior surface of the conduit.
  • the system may be part of an aircraft environmental control system.
  • a method of operating the system as described above comprises the steps of providing a first fluid flow to an inlet of the first flow passage, and a second fluid flow to an inlet of the second flow passage, swirling the fluid flow in the helical flowpaths in the first flow passage, exchanging heat between the first fluid flow and the second fluid flow, and admitting the first fluid flow into the inlet of the matrix.
  • FIG. 1 shows an example heat exchanger in accordance with this disclosure.
  • the heat exchanger comprises a conduit 16.
  • the conduit 16 is annular, and comprises an interior surface 18 and an exterior surface 20.
  • the conduit 16 has a longitudinal axis X.
  • a first flow passage 22 is defined by an interior surface 18 of the conduit 16.
  • a second flow passage 24 is formed radially outwardly of the interior surface 18.
  • the second flow passage 24 extends around less than 50% of the circumference of the conduit 16, for example between 25% and 30% of the circumference.
  • the second flow passage 24 is disposed between the interior surface 18 and the exterior surface 20.
  • the second flow passage 24 may be disposed outwardly of the exterior surface 20 and formed by a separate member suitably attached to the conduit 16.
  • Heat exchange fins 26 project from the interior surface 18 into the first flow passage 22.
  • the fins 26 are distributed around the circumference of the conduit 16, extending inwardly from the portion of the conduit 16 where the second flow passage 24 is disposed. Hence, the fins 26 also extend around less than 50% of the circumference of the conduit 16. In the example shown, the fins 26 extend less than 50% of the distance between the interior surface 18 and the centre of the conduit 16. For example, the fins may extend inwardly between 25 and 50% of the conduit radius.
  • Heat is exchanged between the first flow passage 22 and the second flow passage 24 through the fins 26. Hence, substantial heat exchange only occurs in the portion of the conduit 16 in which the fins 26 and the second flow passage 24 are disposed.
  • FIG. 2 shows another exemplary heat exchanger.
  • both the fins 26 and the second flow passage 24 extend around the entire circumference of the conduit 16. Hence, heat exchange occurs around the entire circumference of the conduit 16.
  • FIG 3 shows another exemplary heat exchanger.
  • second flow passage 24 extends around less than 50% of the conduit 16.
  • the heat exchanger comprises both heat exchange fins 26, which are disposed around the portion of the conduit 16 where the second flow passage 24 is present, and non-exchange fins 28, which are distributed around the remaining portion of the circumference of the conduit 16. Heat exchange only occurs in the portion of the conduit 16 where the second flow passage 24 is disposed.
  • the non-exchange fins 28 largely only act to guide flow (as will be discussed below).
  • FIG. 4A-C there is shown an embodiment of a heat exchanger consistent with Figure 1 .
  • the embodiment of Figure 1 is used only as an example, and the features described below could similarly be present in any of the examples of Figure 2 or 3 .
  • Figure 4A shows an oblique view of the heat exchanger of Figure 1 .
  • the conduit 16 has an inlet 30 and an outlet 32, and is generally of the form as discussed above in relation to Figures 1-3 .
  • the fins 26 are angled relative to a longitudinal axis X of the conduit 16 in order to direct and swirl the flow in the first flow passage 22.
  • the fins 26 form helical flowpaths 27 therebetween in order to direct the flow.
  • the flow in the first flow passage 22 is imparted with an angular momentum in order to 'spin' outward from the outlet 32 of the conduit 16 to an inlet of a downstream matrix (not shown).
  • the flow is more evenly distributed across an inlet of the matrix, particularly at the points of the matrix inlet furthest from the centre of the outlet 32 of the conduit 16.
  • Figures 6 and 7 show a swirled fluid flow from a conduit 2 entering a matrix 4.
  • the flow from the conduit 2 is imparted with an angular momentum by the fins of the heat exchanger.
  • the flow is dispersed downstream to an inlet 6 of the matrix 4.
  • the matrix could be for the purpose of heat exchange or facilitating a chemical reaction. It is envisaged that the matrix could form part of a heat exchanger, or in an arrangement outside of the scope of the present invention, an ozone converter, for an environmental control system of an aircraft.
  • the fins 26 are straight along their length.
  • the fins 26 form an angle with the longitudinal axis X at the outlet 32 of the conduit 30. This angle may be between 10° and 45°. In some examples, the angle may be between 10° and 20°.
  • FIGS 5A-C show an exemplary heat exchanger.
  • the heat exchanger is similar to that of Figures 4A-C , but in this example fins 26 are curved along their length.
  • the fins 26 are straight at the inlet 30 of the conduit 16, and curve to be angled at the outlet 32. Again, the fins 26 form an angle with the longitudinal axis X of the conduit 16 at the outlet 32. The angle may be the same as that discussed in the above "straight-fin" embodiment.
  • the fins 26 could be corrugated along their length to provide increased heat-transfer interaction with the flow in the first flow passage 22.
  • the fins would further be arranged to form a helical flowpath 27 in order to swirl the flow, as discussed above.
  • non-exchange fins 28 could have the form of either of the heat exchange fins 26 of Figures 4A or 5A . These non-exchange fins 28 would also serve to swirl the flow through the first flow passage 22 as discussed above in relation to the heat exchange fins 26.
  • a second set of fins 25 may project into the second flow passage 24. This would provide increased interaction with the fluid flow in the second flow passage 24 to improve heat exchange with a fluid therein.
  • the second set of fins 25 may be aligned with the heat exchange fins 26, or be an extension of the heat exchange fins 26 through the interior surface 18 of the conduit 16. Such an embodiment is illustrated schematically by dotted lines in Figures 4C and 5C .
  • the fins of the second set of fins 25 may be circumferentially offset from the first set of fins 26. For example, they may be positioned circumferentially between the first fins.
  • heat-exchanger fins can be arranged on the interior surface of a conduit which supplies a fluid to a matrix.
  • the fins are angled to form a helical flowpath and thereby as a flow swirler.
  • the conduit can swirl flow for a downstream matrix and provide for heat-exchange.
