Definitions

  • the inlet and outlet headers usually have a conventional cylindrical shape.
  • the vapor phase is usually separated from the liquid phase. Since both phases move independently, refrigerant maldistribution tends to occur.
  • the plurality of parallel mini-channels are serpentine in shape so as to thereby provide a plurality of parallel flow passes but which are connected to the inlet and outlet manifolds only at the respective inlet and outlet ends.
  • the inlet manifold can be relatively short and be directly connected to fewer inlet ends of the microchannels for uniform flow distribution.
  • each circuit has all of its flow passes laterally spaced from all of the flow passes of the adjacent circuits.
  • FIG. 5B is a schematic illustration of a heat exchanger in accordance with the present invention.
  • FIG. 6 is an alternative embodiment thereof.
  • FIG. 5A Considering now the manner in which the tubes may be combined to form a multiple circuit heat exchanger, a prior art, nested, approach is shown in Fig. 5A wherein circuits 48 and 49 are fluidly interconnected between inlet header 51 and 52. Each of the circuits 48 and 49 is formed in a serpentine shape so as to provide five passes between the inlet header 51 and the outlet header 52. This arrangement allows the headers 51 and 52 to be relatively small with the inlet header 51 providing for a single distribution between the two circuits, and with the distribution in each circuit remaining throughout the flow of refrigerant through the heat exchanger. However, in order for the tubes of the circuit 49 to be nested within the tubes of the circuit 48 as shown, their size/shape needs to be selected accordingly.
  • FIG. 6 there is shown an alternative embodiment of a heat exchanger having a five pass, four circuit arrangement to again obtain a total of twenty tubes.
  • the four circuits 63, 64, 66 and 67 are fluidly connected between an inlet header 68 and an outlet header 69, with each of the circuits containing five groups of passes between its inlet and outlet ends.
  • Fig. 7 there are shown two heat exchanger units 70 and 71 in spaced relationship with respect to the direction of airflow therethrough.
