Definitions

  • the present invention relates to an outdoor unit of an air-conditioning apparatus, and a method for manufacturing the same.
  • a heat exchanger is disposed on a back surface and a side surface, and a fan is further disposed on an upper surface.
  • fins for radiating heat transferred from circular tubes or flat tubes are vertically skewered to the circular tubes or the flat tubes through which refrigerant moves.
  • a distance between the bottom plate and a tube disposed on a lowermost column (hereinafter, referred to as a "lowermost column tube”) among the tubes for allowing the refrigerant to flow into the heat exchanger is short.
  • dew condensation water formed by condensing moisture containing air heat-exchanged by the heat exchanger sometimes stays between the lowermost column tube and the bottom plate.
  • the staying dew condensation water causes the corrosion of the lowermost column tube. Additionally, when the staying dew condensation water is frozen, the volume of the dew condensation water is expanded, which causes the breakage and the damage of the lowermost column tube. Additionally, in a case where the lowermost column tube and the bottom plate are made of different kinds of materials, dissimilar metal corrosion (galvanic corrosion) is likely to be generated.
  • connection tubes for supplying the refrigerant to the heat exchanger or connection tubes such as U-bend tubes for mutually connecting a plurality of the tubes of the heat exchanger are connected by brazing.
  • the brazing parts sometimes swell compared to the diameters of the tubes, and a distance between the bottom plate and the tube is further reduced. Therefore, the above problem is more remarkable.

  • Patent Literature 4 discloses an outdoor unit of an air-conditioning apparatus according to the preamble of claim 1.
  • the bottom plate is a member for supporting a structure such as the heat exchanger, and there is a problem that the strength of the bottom plate is lowered when the outlet is formed in the bottom plate.
  • the plurality of louver-like cut-raised parts are provided in the bottom plate, and therefore the opening area of the bottom plate increases. Therefore, there is a problem that air flowing into the outdoor unit flows out from openings of the bottom plate, the air volume of air passing through the heat exchanger reduces, and heat exchange performance lowers. Additionally, the opening area of the bottom plate is large, and therefore there is a possibility that a small animal, snow, or the like are inclined to invade therein through the openings of the bottom plate.
  • the heat exchanger In the outdoor unit of the air-conditioning apparatus, when the heat exchanger is disposed on the bottom plate, the heat exchanger is disposed at a desired position, and therefore a member for positioning the heat exchanger (positioning member) is required.
  • a member for positioning the heat exchanger positioning member
  • a claw is formed in a metal plate provided in the heat exchanger, and this claw is inserted into an opening of the bottom plate, so that the positioning of the heat exchanger is performed.
  • a manufacturing cost increases due to provision of such a positioning member.
  • the present invention has been made to solve the above problems, and a first object is to obtain an outdoor unit of an air-conditioning apparatus capable of making it difficult that dew condensation water stays between a lowermost column tube of a heat exchanger and a bottom plate, and a method for manufacturing an outdoor unit of an air-conditioning apparatus.
  • a second object is to obtain an outdoor unit of an air-conditioning apparatus capable of preventing contact between the lowermost column tube of the heat exchanger and the bottom plate, and a method for manufacturing an outdoor unit of an air-conditioning apparatus.
  • a third object is to obtain an outdoor unit of an air-conditioning apparatus capable of suppressing dissimilar metal corrosion, and a method for manufacturing an outdoor unit of an air-conditioning apparatus.
  • a fourth object is to obtain an outdoor unit of an air-conditioning apparatus capable of suppressing increase in a manufacturing cost, and a method for manufacturing an outdoor unit of an air-conditioning apparatus.

  • Fig. 1 is a perspective view of an outdoor unit of an air-conditioning apparatus according to Embodiment 1 of the present invention.
  • the outdoor unit 1 of the air-conditioning apparatus has a large oblong housing.
  • air inlets 2 for taking air inside are provided in side surfaces and a back surface of the housing.

  • the heat exchanger 5 is formed in, for example, a substantially U-shape, along the air inlets 2. The shape of the heat exchanger 5 is not limited to this.
  • the radiation fins 8 each are made of, for example, aluminum, or an alloy containing aluminum, and each have a plate-like shape. A plurality of the radiation fins 8 are stacked at predetermined intervals, and gas such as air circulates between the radiation fins. Additionally, openings for inserting the plurality of heat transfer tubes 7 are formed in the radiation fins 8, and the heat transfer tubes 7 are inserted into the respective openings, so that the openings are joined to the plurality of heat transfer tubes 7.

  • the heat transfer tubes 7 are connected to a plurality of tubes 10 for allowing the refrigerant to flow, at one end face 9 of the heat exchanger 5.
  • the plurality of tubes 10 are made of, for example, aluminum, or an alloy containing aluminum.
  • the tubes 10 are connected to the heat transfer tubes 7.
  • the present invention is not limited to this, and the heat transfer tubes 7 and the tubes 10 may be integrally formed. That is, the heat transfer tubes 7 may extend beyond the end face 9 of the heat exchanger 5, and extending parts of the heat transfer tubes 7 may be formed as the tubes 10.

  • the axial ends of the heat transfer tubes 7 may be connected to the heat transfer tubes 7 disposed at other columns by using U-bend tubes or the like.
  • Lead tubes 20 are connected to the plurality of tubes 10, respectively. These lead tubes 20 are made of, for example, aluminum, or an alloy containing aluminum. The lead tubes 20 each function as, for example, a joint for connecting the flat tube and the circular tube. The lead tubes 20 are connected to the tubes 10 by brazing 14.

  • dew condensation water obtained by condensing moisture contained in heat-exchanged air sometimes stays in a gap 12 between the lowermost column tube 11 and the bottom plate 6.

  • the area of a part located adjacent to the bottom plate 6 increases compared to a case of the circular tube. That is, the amount of dew condensation water staying between the flat lowermost column tube 11 and the bottom plate 6 increases. Accordingly, the corrosion of the lowermost column tube 11 is likely to be accelerated compared to the circular tube. Additionally, the frozen area of the dew condensation water increases, and a possibility that the lowermost column tube 11 is broken increases compared to the circular tube.
  • the lowermost column tube 11 and the bottom plate 6 are made of different kinds of metals, the lowermost column tube 11 and the bottom plate 6 become conductive by the staying dew condensation water, and a potential difference occurs, which causes dissimilar metal corrosion.
  • the lowermost column tube 11 and the lead tube 20 are connected by the brazing 14, and the brazing 14 swells beyond the tube diameter of the lowermost column tube 11. Therefore, the gap 12 between the brazing 14 and the bottom plate 6 further reduces.
