Definitions

  • a plate fin heat exchanger includes adjacent flow paths that transfer heat from a hot flow to a cooling flow.
  • the flow paths are defined by a combination of plates and fins that are arranged to transfer heat from one flow to another flow.
  • the plates and fins are created from sheet metal material brazed together to define the different flow paths.
  • Thermal gradients present in the sheet material create stresses that can be very high in certain locations. The stresses are typically largest in one corner where the hot side flow first meets the coldest portion of the cooling flow. In an opposite corner where the coldest hot side flow meets the hottest cold side flow the temperature difference is much less resulting in unbalanced stresses across the heat exchanger structure. Increasing temperatures and pressures can result in stresses on the structure that can exceed material and assembly capabilities.
  • Turbine engine manufactures utilize heat exchangers throughout the engine to cool and condition airflow for cooling and other operational needs. Improvements to turbine engines have enabled increases in operational temperatures and pressures. The increases in temperatures and pressures improve engine efficiency but also increase demands on all engine components including heat exchangers.
  • Turbine engine manufacturers continue to seek further improvements to engine performance including improvements to thermal, transfer and propulsive efficiencies.
  • a prior art heat exchanger having the features of the preamble of claim 1 is provided in US 3,692,105 A .

  • the second core and the mold cavity define the plurality of fin portion rows to include additional rows comprised of groups of discrete fin portions disposed between the first row and a last row.
  • the second core and the mold cavity define the plurality of fin portion rows to include a last row spaced furthest from the inlet that includes a continuous fin portion extending uninterrupted from the leading edge to the trailing edge.
  • a heat exchanger 10 includes an inlet manifold 12 and an outlet manifold 14 disposed on either side of a plate assembly 22.

  • the plurality of rows 42 includes features that tailor heat transfer to the extremes of the incoming flows 16, 20 to reduce extremes in thermal gradients.

  • Each of the plurality of discrete fin portions 46 are individual separate segments that are spaced apart longitudinally between the leading edge 30 and the trailing edge 32.
  • the segmented fin portions 46 reduces a heat transfer surface area over which the cooling airflow 20 flows near the inlet 36.

  • a second row 50 from the inlet 36 includes a second group of discrete fin portions 56 that are spaced apart longitudinally between the leading edge and the trailing edge 32.
  • a third row 52 from the inlet 36 includes a third group of discrete fin portions 58 that are spaced apart longitudinally between the leading edge 30 and the trailing edge 32.

  • the first row 48 includes the plurality of the discrete fin portions 46 that each have a common width 66. Each of the fin portions 46 are also spaced a common distance 68.
  • the width 66 and distance 68 tailor the available heat transfer surface area provided by the first row 48 nearest the inlet 36 to minimize heat transfer into the cooling flow 20. Minimizing heat transfer nearest the inlet 36 locally reduces the thermal gradient within the plate assembly 22.
  • the width 66 and distance of the discrete fin portions 46 in the first row 48 is tailored to provide a heat transfer surface area determined to provide an acceptable thermal gradient based on expected temperatures of hot flow 16 and cooling flow 20.
  • the second row 50 includes the second group of discrete fin portions 56 that each have a second common width 70 and a second spacing 72 there between.
  • the second row 50 includes an increased surface area as compared to the first row 48 that is tailored to maintain an acceptable thermal gradient in the plate assembly 22 within the region of the second row 50.
  • the third row 52 of discrete fin portions 58 that have a third common width 74 that are spaced apart a third distance 76.
  • the width 74 and spacing 76 provides another increase in heat transfer surface area compared to each of the first row 48 and the second row 50.

  • the cooling airflow heats up in a direction indicated by arrow 90 and the hot airflow 16 cools down as it proceeds away from the inlet 36 in a direction indicated by arrow 92.
  • the surface area provided by the rows 48, 50 and 52 of discrete fin portions 46, 56 and 58 accommodate the differences in temperatures within the region 64 to reduce stresses and strains on the plate assembly 22 by reducing the differences in thermal gradient encountered by the material comprising the plate assembly 22.
  • the different fin portions are provided relative to a high stress region such as the region 64 or a joint between the plate assembly and one of the inlet manifold 12 and the outlet manifold 14.
  • the asymmetric orientation of fin portions provide benefits within a region disposed within a distance about 10% of the total length of the plate assembly. In another example the distance is within a region about 7% of the total length of the plate assembly.
  • the asymmetric application of heat transfer augmentation features such as the discrete fin portions lower the amount of augmentation feature density by approximately 15%. Additionally, an increase in density up to 200% of the nominal on the external or internal core or joint features.
