Definitions

  • Exemplary embodiments pertain to the art of heat exchangers and, more particularly, to a micro-channel heat exchanger including independent heat exchange circuits.
  • micro-channel heat exchangers include micro-channel tubes formed in a single serpentine path through which passes a coolant or refrigerant.
  • a fluid flow such as air
  • the fluid flow exchanges heat with the refrigerant.
  • the exchange of heat results in a temperature change of the fluid flow.
  • the exchange of heat is enhanced through the addition of fins that extend between the micro- channel tubes.
  • the micro-channel tubes pass between an inlet header and an outlet header. Fins extend between adjacent micro-channel tubes to enhance heat exchange.
  • the inlet and outlet headers are divided into distinct sections. Each section can then be operated independent of the other.
  • a micro-channel heat exchanger including a first micro-channel conduit having a first end section that extends to a second end section through an intermediate section.
  • the intermediate section includes a plurality of substantially straight sections and a plurality of bend sections that establish a first serpentine path.
  • the micro- channel heat exchanger also includes a second micro-channel conduit having a first end portion that extends to a second end portion through an intermediate portion.
  • the intermediate portion includes a plurality of substantially straight portions and a plurality of bend portions that establish a second serpentine path.
  • the first serpentine path extends adjacent to the second serpentine path with the plurality of bend portions being interposed between the plurality of bend sections.
  • the method includes forming a first micro-channel conduit having a first end section that extends to a second end section through an intermediate section, and creating a first serpentine path in the first micro-channel conduit.
  • the first serpentine path includes a plurality of substantially straight sections and a plurality of bend sections.
  • the method also includes forming a second micro-channel conduit having a first end portion that extends to a second end portion through an intermediate portion, and creating a first serpentine path in the second micro-channel conduit.
  • the second serpentine path includes a plurality of substantially straight portions and a plurality of bend portions.
  • the first micro-channel conduit is positioned adjacent the second micro-channel conduit such that the plurality of bend portions are interposed between the plurality of bend sections. Adjacent ones of the plurality of substantially straight sections and substantially straight portions are connected.
  • FIG. 1 depicts a micro-channel heat exchanger including independent heat exchange circuits in accordance with an exemplary embodiment
  • FIG. 2 is a partial detailed view of a first portion of the micro-channel heat exchanger of FIG. 1 ;
  • FIG. 3 is a partial detailed view of a second portion of the micro-channel heat exchanger of FIG. 1 ;
  • FIG. 4 is a partial cut-away view of the second portion of the micro-channel heat exchanger of FIG. 3.
  • Micro-channel heat exchanger 2 includes a first micro-channel conduit 4 that defines a first heat exchange circuit (not separately labeled) and a second micro-channel conduit 6 that defines a second heat exchange circuit (also not separately labeled).
  • First micro-channel conduit 4 includes a first end section 10 that extends to a second end section 11 through an intermediate section 12.
  • First end section 10 is fluidly coupled to an inlet member 14 and second end section 11 is fluidly coupled to an outlet member 15.
  • Inlet member 14 is configured to receive a fluid, for example, a first refrigerant.
  • Intermediate section 12 includes a plurality of substantially straight sections 17-28, a first plurality of bend sections 30-34, and a second plurality of bend sections 40-45 that collectively define a first serpentine path 47.
  • second micro-channel conduit 6 includes a first end portion 60 that extends to a second end portion 61 through an intermediate portion 62. First end portion 60 is fluidly coupled to an inlet member 64 and second end portion 61 is fluidly coupled to an outlet member 65. Inlet member 64 is configured to receive a second fluid such as a second refrigerant. The second refrigerant can be the same as, or distinct from the first refrigerant depending upon desired heat exchange parameters.
  • intermediate portion 62 includes a plurality of substantially straight portions 67-78, a first plurality of bend portions 80-84, and a second plurality of bend portions 90-95 that collectively define a second serpentine path 97 that is fluidly isolated from the first serpentine path 47.
  • Each micro-channel conduit 4, 6 includes a plurality of micro-channels such as indicated at 100 in connection with second micro-channel conduit 6 in FIG. 4.
  • first serpentine path 47 extends adjacent to the second serpentine path 97 with the second plurality of bend portions 40-45 being interposed between the first plurality of bend portions 80-85 and the second plurality of bend portions 90-95 being interposed between the first plurality of bend sections.
  • first micro-channel conduit 4 is interleaved with second micro-channel conduit 6.
  • the term "interleaved" should be understood to describe that a portion of the plurality of straight sections 17-28 extend adjacent to other ones of the plurality of straight sections 17-28, while another portion of the plurality of straight sections 17-28 extends adjacent to select ones of the plurality of straight portions 67-78.
  • a portion of the plurality of straight portions 67-78 extend adjacent to other ones of the plurality of straight portions 67-78, while another portion of the plurality of straight portions 67-78 extend adjacent to select ones of the plurality of straight sections 17-28.
  • micro-channel heat exchanger 2 includes a first plurality of fins or centers 110 and a second plurality of fins or centers 115.
  • First plurality of centers 110 extend between adjacent one of substantially straight sections 17-28 and adjacent ones of the substantially straight portions 67-78. That is, the first plurality of centers 110 extend between substantially straight sections or substantially straight portions associated with the same micro-channel conduit 4 or 6. More specifically, the first plurality of centers 110 are associated solely with either the first serpentine path 47 or the second serpentine path 97.
  • the second plurality of centers 115 extend between adjacent ones of the plurality of straight portions 17-28 and adjacent ones of the plurality of substantially straight portions 67-78.
  • the second plurality of centers 115 extend between substantially straight sections and substantially straight portions associated with the both first micro-channel conduit 4 and micro-channel conduit 6. More specifically, the second plurality of centers 115 join the first and second serpentine paths 47 and 97. At this point, it should be understood that although only two micro-channel conduits are shown, the number of micro-channel conduits employed by micro-channel heat exchanger 2 can vary.
  • refrigerant can be passed through first micro-channel conduit 4, second micro-channel conduit 6 or both first and second micro-channel conduits 4 and 6.
  • first micro-channel conduit 4 and 6 When refrigerant is passed through both micro-channel conduits 4 and 6, a fluid flow passing across the first and second plurality of centers exchanges heat with the refrigerant in both micro-channel conduits 4 and 6.
  • the heat exchange surface area comprises the entire surface area of micro-channel heat exchanger 2.
  • refrigerant is passed through one or the other of first and second micro-channel conduits 4 or 6, a fluid flow passing across the first and second plurality of centers exchanges heat with the refrigerant in flowing in the one of the micro-channel conduits 4 and 6.
  • exemplary embodiments enhance heat exchange in a micro-channel heat exchanger having multiple, distinct circuits. That is, in contrast to prior art arrangements in which only that portion of the fluid flow passing across an active circuit, e.g., upper or lower portions of the heat exchanger, the heat exchanger in accordance with the exemplary embodiment utilizes substantially the entire fluid flow passing over the heat exchanger.
