Definitions

  • the present invention relates to a plate heat exchanger that is used as an evaporator and a condenser.
  • a plate heat exchanger is used as an evaporator that evaporates a first fluid along with heat exchange between the first fluid and a second fluid, and as a condenser that condenses a first fluid along with heat exchange between the first fluid and a second fluid (see Patent Literature 1, for example).
  • a plate heat exchanger generally includes a body portion 3 that includes a plurality of heat transfer plates 2.
  • the body portion 3 includes first channels 30, second channels 31, a pair of first communication passages 32 and 33, and a pair of second communication passages 34 and 35.
  • the first channel 30 circulates a first fluid A.
  • the second channel 31 circulates a second fluid B.
  • the pair of first communication passages 32 and 33 communicate with the first channels 30 to allow the first fluid A to flow into and out of the first channels 30.
  • the pair of second communication channels communicate with the second channels 31 to allow the second fluid B to flow into and out of the second channels 31.
  • the plurality of the heat transfer plates 2 each include at least four openings (no reference numeral is allocated).
  • the plurality of the heat transfer plates 2 are stacked on each other in the body portion 3. With this configuration, the first channels 30 for circulation of the first fluid A and the second channels 31 for the circulation of the second fluid B are alternately formed with the plurality of the heat transfer plates 2 respectively interposed therebetween. With the plurality of the heat transfer plates stacked on each other, each opening of each of the plurality of the heat transfer plates 2 forms a continuous opening extending in the stacked direction of the plurality of the heat transfer plates 2.
  • the one first communication passage 32 for flowing the first fluid A into the first channels 30, the other first communication passage 33 for flowing the first fluid A out of the first channels 30, the one second communication passage 34 for flowing the second fluid B into the second channels 31, and the other second communication passage 35 for flowing the second fluid B out of the second channels 31 extend through the plurality of the heat transfer plates 2 in the stacked direction of the plurality of the heat transfer plates 2 (see Patent Literature 1, for example).
  • a plate heat exchanger 1 of this type the first fluid A supplied into the one first communication passage 32 flows out to the other first communication passage 33 through the first channels 30.
  • the second fluid B supplied into the one second communication passage 34 flows out to the other second communication passage 35 through the second channels 31.
  • the plate heat exchanger 1 enables the heat exchange between the first fluid A and the second fluid B through a large heat transfer surface of each heat transfer plate 2 separating the first channel 30 and the second channel 31.
  • the first communication passages 32 and 33 and the second communication passages 34 and 35 which extend in the stacked direction of the plurality of the heat transfer plates 2 increase in length according to the number of the stacked heat transfer plates 2.
  • the pair of first communication passages 32 and 33 and the pair of second communication passages 34 and 35 each are formed by the alignment of the corresponding openings of the heat transfer plates 2, so that the channel length of each of the pair of first communication passages 32 and 33 and the pair of second communication passages 34 and 35 increases according to the number of the stacked heat transfer plates 2 when the number thereof increases.
  • the distribution resistance of the first fluid A in the first communication channel for flowing the first fluid A into the first channels 30 (the one first communication channel) 32 increases and thus the first fluid A is not easy to circulate. Therefore, in the plate heat exchanger 1 of this type, the inflow of the first fluid A into the first channels 30 at the inlet side of the one first communication passage 32 and the inflow of the first fluid A into the first channels 30 at the far side of the one first communication passage 32 become uneven. That is, in the plate heat exchanger 1 of this type, distribution unevenness of the first fluid A is caused in the plurality of the first channels 30 aligning in the stacked direction of the heat transfer plates 2.
