Definitions

  • the present invention relates to an outdoor unit of an air-conditioning apparatus.
  • An existing outdoor unit of an air-conditioning apparatus is provided with, for example, a cross fin pipe type heat exchanger including: a heat exchange unit composed of fins made of an aluminum material and circular pipes made of a copper material; and heat exchanger side plates provided at end surfaces of the fins.
  • a lower surface of the cross fin pipe type heat exchanger is a flat surface which is formed by the uniform-width flat fins and has no step.
  • the cross fin pipe type heat exchanger is installed in the outdoor unit in a state where the fins are in surface contact with a base plate.
  • a partition plate which separates a machine chamber and a blower chamber is fixed to the base plate by means of screws, and a back panel is fixed to the base plate by means of screws.
  • the partition plate and the back panel are in contact with the heat exchanger side plates, and fixed thereto by means of screws at screw hole portions provided at contact surfaces thereof, whereby it is possible to position the end surfaces of the heat exchanger and stably fix the heat exchanger to a housing.
  • an outdoor unit of an air-conditioning apparatus there is an outdoor unit provided with a parallel pipe type heat exchanger in which a plurality of flattened pipes and corrugated fins between the adjacent flattened pipes are arranged between two cylindrical header pipes. End portions of the cylindrical header pipes at four corners of such a parallel pipe type heat exchanger are configured to form steps that are convex with respect to the uppermost surface or the lowermost surface of the fin.
  • a parallel pipe type heat exchanger in which aluminum is used as the material of fins and pipes is fixed to an outdoor unit via a spacer made of a metal electrically less noble than (a metal having higher ionization tendency than) aluminum, thereby suppressing pitting corrosion of an aluminum pipe caused by electrolytic corrosion with iron forming a housing of the outdoor unit (for example, Patent Literature 2) is hitherto known.
  • the parallel pipe type heat exchanger is positioned at only two points on a lower end thereof, and thus an upper end portion thereof is not restrained and is in a free state with the lower end as a fulcrum point. Therefore, when the parallel pipe type heat exchanger is mounted on the base plate so as to be tilted relative to the base plate or when the heat exchanger vibrates and oscillates during transport or operation, excessive stress is applied to a connected refrigerant pipe, cracks occur in the refrigerant pipe, and a trouble such as refrigerant leak or generation of abnormal sound occurs.
  • the present invention has been made in view of the above-described problems, and it is an object of the present invention to obtain an outdoor unit of an air-conditioning apparatus which suppresses electrolytic corrosion of a heat exchanger and has high reliability.
  • An outdoor unit of an air-conditioning apparatus includes: a partition plate separating a blower chamber and a machine chamber; a heat exchanger having a header pipe; a base plate on which the partition plate and the heat exchanger are placed; a first spacer mounted on a portion of the header pipe and covering the portion of the header pipe; and a fixing member mounted on the first spacer and fixing the heat exchanger via the first spacer.
  • the first spacer is made of a resin or a metal that is less noble than a metal forming the heat exchanger.
  • the fixing member is mounted on the header pipe via the first spacer.
  • Fig. 1 is a perspective view of an outdoor unit 100 of an air-conditioning apparatus according to Embodiment 1 of the present invention.
  • Fig. 2 is a front view of a heat exchanger 1 provided in the outdoor unit 100. The configuration and operation of the outdoor unit 100 will be described based on Figs. 1 and 2 .
  • the outdoor unit 100 includes the heat exchanger 1, a base plate 3, a back plate 4, a partition plate 5, and screws 6.
  • the heat exchanger 1 is composed of, for example, a parallel pipe type heat exchanger made of aluminum, and is provided at a back side of the outdoor unit 100.
  • the heat exchanger 1 will be described in detail later.
  • the base plate 3 has a box shape whose upper surface is opened, and forms a bottom portion of the outdoor unit 100. Components such as the heat exchanger 1 accommodated in the outdoor unit 100 are placed on the base plate 3.
  • the back plate 4 is a plate forming a side portion and a part of a back portion of the outdoor unit 100.
  • the partition plate 5 is a plate which separates a blower chamber 70 in which a fan (not shown) and the like are provided and a machine chamber 80 in which a compressor (not shown) and the like are provided.
  • the screws 6 are members for fastening a plurality of components within the outdoor unit 100.
  • means for fixing a plurality of components within the outdoor unit 100 to each other as described above are not limited to only the screws 6, and, for example, a plurality of components may be processed and engaged with each other, whereby the components are fixed to each other.
  • a plurality of the screws shown in Fig. 1 are illustrated as screws 6 provided within the outdoor unit 100, and the number of the screws 6 is not limited thereto.
  • the screws 6 correspond to "fixing means" of the present invention.
  • the heat exchanger 1 includes header pipes 7a and 7b, flattened pipes 10, radiation fins 11, side plates 12, and a header pipe partition plate 13.
  • the header pipes 7a and 7b are cylindrical pipes provided at both ends of the heat exchanger 1, and are arranged parallel to each other.
  • An inlet pipe 8 connected to a discharge pipe (not shown) connected to a compressor and a discharge pipe 9 connected to an expansion pipe (not shown) of an expansion unit (not shown) are connected to the header pipe 7a, whereby a refrigerant circuit is formed.
  • the inlet pipe 8 and the discharge pipe 9 project toward the machine chamber 80 side. It should be noted that when flow of a refrigerant is reversed, the inlet pipe 8 is connected to the expansion pipe of the expansion unit, and the discharge pipe 9 is connected to the above discharge pipe.
  • the header pipes 7a and 7b are sometimes collectively referred to as header pipe 7.
  • the flattened pipes 10 are a plurality of pipes which are provided between the header pipes 7a and 7b and are arranged perpendicularly to the header pipes 7a and 7b, namely, parallel to each other at equal intervals in the longitudinal direction of the header pipes 7a and 7b, and a passage in which the refrigerant flows is provided within the flattened pipes 10.
  • the header pipes 7 and the flattened pipes 10 are joined to each other, for example, by a brazing filler material, whereby the insides of the header pipes 7 and the insides of the flattened pipes 10 communicate with each other.
  • the radiation fins 11 are, for example, corrugated fines provided on both surface of each flattened pipe 10, and a plurality of the radiation fins 11 are arranged at regular intervals so as to extend in a horizontal direction.
  • the side plates 12 serve to suppress deformation of the radiation fins 11, and each are disposed at a single surface of each of the outermost radiation fins 11 (uppermost and lowermost in Fig. 2 ).
  • the header pipe partition plate 13 is a member used for efficient heat exchange to be performed in the heat exchanger 1, and is provided within the header pipe 7a.
  • the header pipe partition plate 13 is located at a position lower than the inlet pipe 8 and higher than the discharge pipe 9.
  • the refrigerant flows in the discharge pipe, flows into the inlet pipe 8 in the direction of an arrow 14a (in the upward direction relative to the sheet), and flows into the flattened pipes 10 via the header pipe 7a in the heat exchanger 1.
  • the refrigerant is distributed in an upper space separated by the header pipe partition plate 13 in the header pipe 7a and flows in each flattened pipe 10.
  • the refrigerant having flowed into the flattened pipes 10 flows in the direction of an arrow 14b (in the rightward direction on the sheet) toward the header pipe 7b and flows into the header pipe 7b.
  • the refrigerant flowing in the header pipe 7b flows in the direction of an arrow 14c (in the downward direction relative to the sheet) and flows into the flattened pipes 10 again.
  • the refrigerant having flowed in the direction of the arrow 14b (in the rightward direction relative to the sheet) and having flowed in from the flattened pipes 10 is split in the header pipe 7b and distributed to the flattened pipes 10 that communicate with the discharge pipe 9.
  • the refrigerant having flowed into the flattened pipes 10 again flows in the direction of an arrow 14d (in the leftward direction on the sheet) toward the header pipe 7a and flows out through the discharge pipe 9 in the direction of an arrow 14e (in the leftward direction on the sheet) as a condensed refrigerant.
  • the refrigerant flows in the direction reverse to that when the heat exchanger 1 is used as a condenser.
  • the refrigerant flows in the discharge pipe 9, the header pipe 7a, the flattened pipes 10, the header pipe 7b, the flattened pipes 10, the header pipe 7a, and the inlet pipe 8 in this order.
  • all the materials of the header pipe 7, the inlet pipe 8, the discharge pipe 9, the flattened pipes 10, the radiation fins 11, the side plates 12, and the header pipe partition plate 13 are an aluminum material or a metal that is less noble than the material of a later-described fixing member 17.
  • the flattened pipes 10 and the radiation fins 11, the radiation fins 11 and the side plates 12, and the header pipe 7 and the inlet pipe 8 and the discharge pipe 9 are joined to each other by a brazing filler material.
  • Fig. 3 is a perspective view of the heat exchanger 1 provided in the outdoor unit 100.
  • a first spacer 15a is mounted on the upper end of the header pipe 7a
  • a first spacer 15b is mounted on the lower end of the header pipe 7a.
  • the first spacers 15 are interposed between the heat exchanger 1 and the fixing member 17 when the later-described fixing member 17 is fixed to the heat exchanger 1.
  • first spacers 15a and 15b are sometimes referred to collectively as "first spacer 15.”
  • first spacers 15a and 15b are illustrated as being mounted on the upper end and the lower end of only the header pipe 7a, and it goes without saying that first spacers 15a and 15b are similarly mounted also on the header pipe 7b. Since the first spacer 15 is mounted also on the lower end of the header pipe 7b, when the heat exchanger 1 is placed on the base plate 3, the first spacers 15b mounted on the lower ends of the respective header pipes 7a and 7b come into contact with the base plate 3, and thus it is possible to assemble the outdoor unit 100 in a state where the heat exchanger 1 is kept stable.
  • first spacer 15a is provided on the upper end of the header pipe 7a and the first spacer 15b is provided on the lower end of the header pipe 7a, but the present invention is not limited thereto.

  • the material of the first spacer 15 is not limited to the resin, and may be a metal that is electrically less noble than the material of the heat exchanger 1 (aluminum).
  • the first spacer 15 is configured to be able to sandwich the header pipe 7 from outside.
  • the first spacer 15 includes: a main body portion 15A including a front surface portion 15e, a back surface portion 15f, an outer surface portion 15g, an upper surface portion 15h, and a lower surface portion 15i; and a header retaining portion 15B including a front-side extending portion 15j, a back-side extending portion 15k, and a header pipe insertion groove 15c formed between the front-side extending portion 15j and the back-side extending portion 15k.

  • the front-side extending portion 15j and the back-side extending portion 15k are formed so as to be thinner than the front surface portion 15e and the back surface portion 15f, and are elastically deformable.
  • the upper surface portion 15h is formed such that its length between the front-side extending portion 15j and the back-side extending portion 15k is narrower than the header pipe 7 and its length between the front surface portion 15e and the back surface portion 15f is equal to the outer diameter of the header pipe 7.
  • the first spacer 15 is configured to be mountable on and dismountable from the header pipe 7.
  • a screw hole 16 (screw holes 16a and 16b in Fig. 3 ) is formed in the outer surface of the first spacer 15 and fixed to the later-described fixing member 17 by means of screws.
  • the screw hole 16 is formed with such a depth as to not reach the inner surface, so that when a screw 6 is inserted into the screw hole 16, the screw 6 does not penetrate therethrough to the inner surface.
  • a screw 6 made of iron which is less expensive, is used and rusted, it is possible to restrain water containing ions of iron, which is a metal that is electrically nobler than (a metal having lower ionization tendency than) aluminum, from reaching the heat exchanger 1.
  • the first spacer 15b is mounted such that when the heat exchanger 1 is assembled to the outdoor unit 100, the first spacer 15b comes into contact with the base plate 3, and the contact surface area thereof with the base plate 3 is larger than that of the bottom surface of the header pipe 7. Thus, the heat exchanger 1 is not tilted, and it is possible to stably assemble the outdoor unit 100.

It should be noted that the number of the ribs 15d is not limited to three.
