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 and other high temperature applications. 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.
  • plate stack heat exchangers have been designed to have a large product of heat transfer coefficient and heat transfer surface area to achieve a large amount of heat transfer in a small volume.
  • this product of heat transfer coefficient and heat transfer surface area increases on the hot side of a plate stack heat exchanger, the metal temperature increases.
  • a heat exchange device includes a plurality of flow passages. Each flow passage has an inlet and an outlet configured for hot fluid flow in a direction from the inlet to the outlet. Secondary heat transfer elements within and adjacent each flow passage have heat transfer characteristics varying in the direction of the hot fluid flow such that peak metal temperatures limit creep to acceptable values and such that transient thermal stresses are limited to values producing acceptable life of the device.
  • the heat transfer elements can be positioned proximate the inlet and the outlet and gradually transition from straight heat transfer elements at the inlet to shaped heat transfer elements proximate the outlet.
  • Proximate the inlet of each flow passage can include a first predetermined number of straight heat transfer elements.
  • An intermediate section between the inlet and outlet of the flow passage can include a second predetermined number of straight heat transfer elements and a third predetermined number of shaped heat transfer elements, wherein the second predetermined number is greater than the first predetermined number.
  • Proximate the outlet of the flow passage can include a fourth predetermined number of shaped heat transfer elements greater than the third predetermined number of shaped heat transfer elements.
  • the device can further include a first section and a second section.
  • Each of the first and second sections including the flow passages, wherein each flow passage includes heat transfer elements positioned to provide increased heat transfer in a direction from the inlet to the outlet.
  • the first and second sections can include plate sections in a stacked arrangement with each of the flow passages having a bend at an outer edge of the heat exchange device configured to return high pressure fluid to a center manifold.
  • the center manifold can include a first plenum at one end configured to allow fluid to enter the center manifold and a second plenum on the opposing side configured to allow fluid to exit the center manifold. Hot fluid can flow through the first plenum into an inlet of a respective flow passage within the first and second sections, enters the center manifold through and outlet of the respective flow passage, and exits the center manifold through the second plenum.
  • a heat exchange device includes a first section and a second section.
  • Each of the first and second sections including flow passages configured to cool fluid, each of the flow passages having an inlet and outlet wherein each flow passage includes heat transfer fins positioned proximate the inlet to the outlet and gradually transition from straight fins at the inlet to shaped fins proximate the outlet.
  • a center manifold disposed between the first and second sections, wherein hot fluid enters the manifold at a first plenum, passes through the first and second sections and exits the center manifold at a second plenum.
  • FIG. 2 a partial view of an exemplary embodiment of a heat exchange device in accordance with the disclosure is shown in Fig. 2 and is designated generally by reference character 100.
  • the systems and methods described herein can be used in turbine engines exposed to high pressure and high temperatures, for example in aerospace application.
  • the present disclosure provides for a device that reduces the product of heat transfer coefficient and heat transfer surface area in regions of the device where metal temperatures must be limited to meet life requirements, while still maintaining a large product of heat transfer coefficient and heat transfer surface area where large amounts of heat transfer per unit heat exchanger volume and weight can be achieved with reasonably low metal temperatures from a structural perspective between the hot and cold fluids.
  • a typical heat exchanger known in the prior art is shown.
  • Hot fluid enters through an inlet 20 at one end and passes through fin channels in flow passages to an outlet 22 at an opposing end.
  • Cold fluid is passed surrounding the flow passages to transfer heat between the hot fluid within the flow passages and the cold fluid.
  • Typical heat exchangers include secondary heat transfer elements, such as fins 10, within each flow passage. As shown in Fig. 1 and in more detail in Fig. 1A , generally these fins extend from the inlet 20 to the outlet 22 and are equal in dimensions throughout the length of the flow passage 10. As shown in Fig. 1A , fins 10 are herringbone fins that extend from the inlet 20 to the outlet 22.
  • fins 132 in accordance with the present disclosure are shown. Fins 132 are included within each of the flow passages 110 and fins 134 extend from the flow passages 110.
  • the fins 132, 134 form a solid matrix to provide thermal and structural connection. Fins 132 provide increased heat transfer in a direction from the inlet 120 to the outlet 122.
  • Straight fins 132a are positioned proximate the inlet 120 where creep and transient thermal stresses are greatest. The straight fins 132a transition to shaped fins 132b at the outlet 122 where enhanced thermal performance is desired.
  • the shaped fins 132b allow for increased extended secondary heat transfer surface area or increased heat transfer coefficient, which is more desirable at the outlet 122.
  • the device allows for peak metal temperatures and thermal transient stresses that are limited such that the device meets specified life requirements for a specified set of operating conditions or duty cycle.
  • Fins 132 can be within each flow passage 110 and/or adjacent each flow passage 110. This allows the metal temperature in any given region of the device to be affected by the heat transfer characteristics of the heat transfer elements on both the hot and cold fins.
  • a first predetermined number of straight fins 132a can be positioned proximate the inlet 120.
  • An intermediate section of the flow passage 110 between the inlet 120 and outlet 122 can include a second predetermined number of straight fins 132a and a third predetermined number of shaped fins 132b, where the second predetermined number of straight fins 132a is greater than the first predetermined number 132a.
  • a fourth predetermined number of shaped fins 132b can be included that is less than the third predetermined number of shaped fins 132b.
  • the device includes a first section 102 and a second section 104.
  • the first and second sections 102, 104 are two identical heat exchange plate core sections each made up of flow passages 110 configured for heat exchange between heat exchange fluid within the flow passages 110 and fluid external of the fluid passages 110.
  • Each of the flow passages 110 includes an inlet 120 and an outlet 122 (as shown in Fig. 2 ) with a bend or loop 130 at the outer edges of the device 100 to return the fluid to a center manifold 106.
  • the bulk of the heat transfer occurs within the flow passages 110 of the first and second sections 102, 104.
  • the center manifold 106 separates the first and second sections 102, 104 and is configured to allow high pressure fluid to enter the manifold 106 at one end 112, pass into the flow passages 110 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 facilitates installation of the proposed heat exchange device 100 in place of an existing tube-shell unit.
