Definitions

  • the present disclosure relates to heat exchangers, and more particularly to plate-stack heat exchangers.
  • Heat exchangers such as, for example, tube-shell heat exchangers, are typically used in aerospace turbine engines. These heat exchangers are used to transfer thermal energy between two fluids without direct contact between the two fluids.
  • a primary fluid is typically directed through a fluid passageway of the heat exchanger, while a cooling or heating fluid is brought into external contact with the fluid passageway. In this manner, heat may be conducted through walls of the fluid passageway to thereby transfer energy between the two fluids.
  • One typical application of a heat exchanger is related to an engine and involves the cooling of air drawn into the engine and/or exhausted from the engine.
  • US 6035927 A relates to a tube/fin block for a heat exchanger and manufacturing process therefor.
  • US 2013201628 A1 relates to a radiator and electronic apparatus including same.
  • US 2883165 A1 relates to a heat exchanger core.
  • a heat exchanger according to the preamble of claim 1 is known e.g. from document US 6035927 A .
  • a heat exchange device includes a first section and a second section.
  • Each of the first and second sections include flow passages configured for heat exchange between hot fluid within the flow passages and cold fluid external of the flow passages.
  • Each of the flow passages having cold fluid flow therebetween.
  • a separator is positioned dividing the cold fluid flow between flow passages.
  • the separator includes two separator sheets spaced apart with a pillar matrix structurally connecting the separator sheets configured to prevent cold fluid mixing.
  • Each of the flow passages can have a hot fluid inlet and a hot fluid outlet wherein the temperature of the fluid entering at the hot fluid inlet is greater than the temperature of the fluid exiting the hot fluid outlet.
  • the separator sheets can be positioned between each hot fluid inlet and hot fluid outlet of each adjacent flow passage configured to provide insulation between the different temperatures of the hot fluid inlet and the hot fluid outlet.
  • the cold fluid flow channel includes secondary heat transfer element such as fins, pins or vanes extending from the flow passages.
  • the pillar matrix can be between the two separator sheets and include the same material as that of the cold fins.
  • the pillar matrix can include material with reduced thermal conductivity relative to other material of the device in order to reduce thermal conduction.
  • a center manifold is disposed between the first and second sections.
  • Hot fluid can enter the manifold at one end, pass through the first and second sections and hot fluid exits the manifold at the opposing end.
  • the hot fluid entering the flow passage can be greater in temperature than the hot fluid entering the manifold upon exiting the flow passage.
  • Each of the first and second sections include heat exchanger plates with secondary heat transfer elements in a stacked arrangement.
  • the secondary heat transfer elements and flow passages can form a solid matrix configured to prevent wear of the device and prevent relative motion with the device.
  • the components of the heat exchange device can be created through the use of additive manufacturing.
  • FIG. 1 a partial view of an exemplary embodiment of a heat exchange device in accordance with the disclosure is shown in Fig. 1 and is designated generally by reference character 100.
  • FIGs. 2-4 Other embodiments of the heat exchange device in accordance with the disclosure, or aspects thereof, are provided in Figs. 2-4 , as will be described.
  • the systems and methods described herein can be used in turbine engines exposed to high pressure and high temperatures, for example in aerospace application.
  • a heat exchange device 100 in accordance with the present disclosure is shown.
  • the device includes a first section 102 and a second section 104 separated by a center manifold 106.
  • the first and second sections 102, 104 are two identical plate-fin core sections each made up of flow passages 110 configured for heat exchange between hot heat exchange fluid within the flow passages 110 and cold fluid external of the fluid passages 110. It will be understood by one skilled in the art that the cold and hot fluids can be interchanged.
  • Each of the flow passages 110 includes a bend or loop 130 at the outer edges of the device 100 to return the fluid to the center manifold 106. The bulk of the heat transfer occurs within the flow passages 110 of the first and second sections 102, 104.
  • each of the flow passages includes a fluid inlet 120 and a fluid outlet 122 connecting the flow passages to the center manifold 106. Fluid temperature entering from the fluid inlets 120 is greater than fluid temperature exiting from the fluid outlets 122.
  • Fins 132 are included within each of the flow passages 110 and cold fins 134 extend from the flow passages 110. The fins 132, 134 act as heat transfer elements and form a solid matrix to provide thermal and structural connection. Parting sheets 136 are positioned above and below fins 132 to prevent fluid mixing.
  • the center manifold design will behave like typical single-pass cross-flow heat exchanger with the low pressure fluid mixed, resulting in reduced efficiency relative to a typical plate-fin cross-flow heat exchanger where both hot and cold fluids remain unmixed throughout the heat exchanger. This results in an increase in size and weight of roughly 20% in some cases to achieve the same heat transfer performance as a true single-pass cross-flow heat exchanger.
  • a separator 144 is positioned to divide cold fluid flow between adjacent flow passages.
  • the separator 144 is a mostly hollow structure comprised of two thin, solid separator sheets 140 supported with intermittently spaced pillar-like or vane-like structures, defining a pillar matrix 142.
  • the separator 144 is positioned between cold fins 134 of each flow passage 110 and configured to provide insulation between the fluid inlets 120 and fluid outlets 122 of the each flow passage to allow for reduced conductance normal to the plane of the sheets which is minimized by incorporating only as much material (i.e.
  • the pillar matrix 142) between the upper and lower separator sheets 140 as is required to meet structural requirements or to facilitate production with additive or other manufacturing methods. Because the high pressure loading forces on the high pressure sides are reacted by fins in the high pressure layer in tension, the fins in the lower pressure layers are not supporting high pressure loads and therefore neither the cold side fins nor the pillars between the separator sheets require the same high strength material properties of the parting sheets and fins in the high pressure layers. Therefore, the fins in the lower pressure layers and pillars between the separator sheets add only enough structural rigidity to move core resonant modes out of the region of concern.
  • the center manifold 106 is configured to allow high pressure fluid to enter the manifold 106 at one end 112, pass into the flow passages 102, 104 on either side of the manifold 106, and return to the manifold 106 to exit the manifold 106 at the opposite end 114. More specifically, the center manifold 106 includes a first plenum 112a at one end and a second plenum 114a on an opposing end.
  • the design for the first and second sections 102, 104 and the center manifold 106 facilitate installation of the proposed heat exchange device 100 in place of an existing tube-shell unit.
  • thermo separator to prevent cold flow mixing and reduce heat conduction between flow passage inlets and outlets.
