Definitions

  • the present invention relates to an outdoor unit for an air-conditioning apparatus including a heat exchanger in which a plurality of heat exchanger units are vertically stacked.
  • a holding part is interposed between each two of a plurality of heat exchanger units each bent into an L-shape or a U-shape at a part of the heat exchanger unit to stably and vertically stack the plurality of heat exchanger units.
  • JP 2008 151392 A discloses an outdoor unit comprising a heat exchanger including a plurality of exchanger units, wherein the plurality of heat exchanger units are vertically stacked and each including a long side portion, a short side portion, and a bent portion connecting the long side portion and the short side portion. Moreover, a misalignment preventing member is inserted between one pair of the plurality of heat exchanger units being vertical adjacent and has a base plate corresponding to a curve shape and a size of the benting portion of the pair of heat exchanger units.
  • Patent Literature 1 Japanese Unexamined Patent Application Publication No. 2009-79851
  • the holding part regulates a large range of linear portions and corner portions of the heat exchanger units that are each bent into an L-shape or a U-shape at a part of the heat exchanger unit. Consequently, when the heat exchanger units vary in bending angles, and the bending angles of the heat exchanger units that are vertically adjacent to each other are not equal, adjustment of the bending angles of the heat exchanger units is required at the time of assembly. As a result, the number of assembly steps is increased, or assembly time is elongated. Thus, there is a problem in assembly efficiency.
  • the present invention has been made to solve the problems described above, and has an object to provide an outdoor unit for an air-conditioning apparatus that improves assembly efficiency through elimination of need for adjustment of bending angles of heat exchanger units at the time of assembly, and prevents an uneven surface due to deviation in an air flow direction of the heat exchanger units that are vertically stacked at a part, such as a back surface of the outdoor unit, at which an installation worker or a user can touch the heat exchanger units that are vertically stacked.
  • the deviation in the air flow direction that lies between the ones of the plurality of heat exchanger units that are vertically adjacent to each other is larger at the short side portions than at the long side portions. Consequently, assembly efficiency can be improved through elimination of need for adjustment of the bending angles of the heat exchanger units at the time of assembly. Further, it is possible to prevent the uneven surface due to the deviation in the air flow direction of the heat exchanger units that are vertically stacked at the part at which the long side portions are arranged, such as the back surface of the outdoor unit, at which an installation worker or a user can touch the heat exchanger units that are vertically stacked.
