The condensed and liquefied refrigerant passes through the fully-opened first expansion valve 9 and is sent to the indoor unit 2 through the liquid blocking valve 10 and the liquid side connection pipe 3. The liquid refrigerant that has flowed into the indoor unit 2 is decompressed and expanded by the second expansion valve 13 to form a low-temperature low-pressure gas-liquid two-phase flow, and enters the indoor heat exchanger 12, where indoor air, etc. The heat exchange with the use side medium cools the use side medium, and itself evaporates and evaporates. Thereafter, the gas refrigerant passes through the gas side connection pipe 4, passes through the gas blocking valve 11, the four-way valve 7, and the accumulator 5 to return to the compressor 6 to constitute a refrigeration cycle. The surplus refrigerant of the refrigeration cycle is stored in the accumulator 5, and is configured to maintain the operating pressure and temperature of the refrigeration cycle in a normal state.

  The refrigeration cycle apparatus 100 operates as follows when performing the heating operation. The high temperature / high pressure gas refrigerant compressed by the compressor 6 is discharged from the compressor 6 together with the refrigerator oil, passes through the four-way valve 7, the gas blocking valve 11, and the gas side connection piping 4 to the indoor side heat exchanger 12 of the indoor unit 2. It flows in and exchanges heat with the use side medium such as room air, heats the use side medium, and condenses and liquefies itself. The condensed and liquefied refrigerant passes through the liquid side connection pipe 3 and the liquid blocking valve 10, is decompressed by the first expansion valve 9, and exchanges heat with a heat source medium such as outdoor air in the outdoor heat exchanger 8 to evaporate. . The evaporated and vaporized refrigerant constitutes a refrigeration cycle in which it returns to the compressor 6 through the four-way valve 7 and the accumulator 5.

  The outdoor heat exchanger 8 etc. which comprise the outdoor unit 1 shown in FIG. 1 are normally installed in the inside of a housing | casing. FIG. 2 is a plan view showing the inside of the outdoor unit 1 with the top plate removed. The casing 20 of the outdoor unit 1 is provided with a top plate (not shown), a bottom plate 21 and side plates 22 to 25, and the internal space thereof is divided by a partition plate 26 into a heat exchange chamber 31 and a machine chamber 32. It is done. The outdoor heat exchanger 8 and the blower 30 are disposed in the heat exchange chamber 31, and the accumulator 5, the compressor 6, and the like are disposed in the machine chamber 32. The side plates 22 to 25 are a machine room side front side plate 22, a machine room side rear side plate 23, a heat exchange chamber side front side plate 24 and a heat exchange chamber side rear side plate 25. The machine room 32 is composed of a machine room side front side plate 22, a machine room side rear side plate 23 and a partition plate 26. On the other hand, the heat exchange chamber 31 includes the heat exchange chamber side front side plate 24 and the heat exchange chamber side rear side plate 25, and further, between the machine chamber side rear side plate 23 and the heat exchange chamber side rear side plate 25 and the heat exchange chamber The air inlets 27 and 28 respectively provided between the side front side plate 24 and the heat exchange chamber side rear side plate 25 are provided. The intake ports 27, 28 are air intake ports. Furthermore, the heat exchange chamber side front side plate 24 is provided with an exhaust port 29 for discharging the air heat-exchanged by the outdoor heat exchanger 8 from the front surface of the outdoor unit 1. With such a structure, the air sucked from the air inlets 27 and 28 provided on the back surface and the side surface of the outdoor unit 1 by the blower 30 is heat-exchanged by the outdoor heat exchanger 8, and then provided on the front surface of the outdoor unit. The exhaust port 29 can be discharged to the outside of the outdoor unit 1.

  The outdoor heat exchanger 8 in the refrigeration cycle apparatus (air conditioner) 100 shown in FIGS. 1 and 2 is, in this embodiment, two header manifolds 41 made of aluminum (hereinafter, including an aluminum alloy), A plurality of aluminum flat heat transfer tubes 43 arranged vertically between the header collecting pipe 42, one end connected to one header collecting pipe 41, and the other end connected to the other header collecting pipe 42; A plurality of fins 44 made of aluminum joined to the flat heat transfer tube 43 is formed.

The configuration of the outdoor heat exchanger 8 will be described with reference to FIG. FIG. 3A is a front view of the outdoor heat exchanger 8.
As shown in FIG. 3A, the outdoor heat exchanger 8 includes a header collecting pipe 41, a header collecting pipe 42, a plurality of flat heat transfer pipes 43, and a plurality of fins 44, each of which is made of aluminum. These members are joined together by brazing (the bending of the outdoor heat exchanger 8 in FIG. 2 is neglected).
The header collecting pipe 41 and the header collecting pipe 42 are formed in an elongated cylindrical shape whose both ends are closed, and are arranged at a predetermined interval so that the longitudinal direction is vertical. Connected to the header collecting pipe 41 are an aluminum gas pipe 45 serving as an inlet / outlet of gas refrigerant and an aluminum liquid pipe 46 serving as an inlet / outlet of liquid refrigerant.

  As shown in FIG. 3B, the flat heat transfer tube 43 has an oblong shape whose cross section in the short direction is flat, and a plurality of refrigerant channels 47 are formed inside. The plurality of flat heat transfer tubes 43 are arranged in the up-down direction so as to be parallel to each other at a constant distance, with the long side surfaces facing each other. One end of the plurality of flat heat transfer tubes 43 is connected to the header collecting pipe 41, and the other end is connected to the header collecting pipe 42, and the refrigerant flow path inside thereof is the header collecting pipe 41 and the header collecting pipe 42 It is in communication.

  The fins 44 have a longitudinally long plate shape in which cuts are formed by press processing, and the outdoor heat exchanger 8 has a structure in which the flat heat transfer tubes 43 are inserted into the fins 44. The distance between adjacent fins 44, so-called fin pitch, is, for example, about 1.5 mm. On the other hand, the distance between the header collecting pipe 41 or 42 and the outermost fin 44 adjacent thereto is, for example, about 20 mm, which is ten times or more of the fin pitch. Therefore, air is more likely to flow around the header collecting pipes 41 and 42 and toward the section between the header collecting pipes 41 and 42 and the outermost fins 44 compared with the space between the fins 44 and the fins 44.

  A support bracket 51 (see FIGS. 2 and 4) for blocking the flow of air is provided between the header manifold 41 and the outer fin 44 closest to it. Similarly, a support bracket 52 (FIG. 2) is provided between the header manifold 42 and the nearest outer fin 44 to block the flow of air. Hereinafter, support brackets 51 and 52 for blocking the flow of air will be described around the header collecting pipes 41 and 42 and in the sections between the header collecting pipes 41 and 42 and the outermost fins 44 (representative Then, an example of the support bracket 51 will be mainly described). The support bracket 51 (see FIGS. 2 and 4) and the support bracket 52 (see FIG. 2) have the same structure. FIG. 4 is a perspective view of the vicinity of the header manifold 41 on the machine chamber 32 side, and FIG. 5 is a front view of the support bracket 51. The support bracket 51 is formed with a hole 63 for passing the flat heat transfer tube 43 (see FIG. 5), and is disposed between the header manifold 41 and the fin 44 so as to be closer to the fin 44 side. The support bracket 51 includes supported portions 61 and 62, and the cross-sectional shape in the short direction of the support bracket 51 including the supported portions 61 and 62 is U-shaped so as to sandwich the flat heat transfer tube 43. I am Of course, as long as the air flow can be shut off, it may be configured in various shapes such as a U-shape and a V-shape. The support bracket 51 is made of aluminum, and is joined to the flat heat transfer tube 43 or the header collecting pipe 41 at the same time as joining the respective members of the outdoor heat exchanger 8 by brazing. Fixing members 70 (described later) for fixing the machine room side rear side plate 23 (FIG. 2) and the partition plate 26 (FIG. 2) to the supported portions 61 and 62 respectively according to the height of the support bracket 51. A plurality is provided. Further, auxiliary members 39 are provided between the fixing members 70 aligned in the vertical direction.

On the machine room 32 side, as shown in FIG. 2, the supported portion 61 of the support bracket 51 located on the upstream side of the air flowing through the outdoor heat exchanger 8 corresponds to the machine room rear side plate 23 of the housing 20. The supported portion 62 which is fixed and supported and located on the downstream side is fixed and supported by the partition plate 26.
Furthermore, also on the heat exchange chamber 31 side, the supported portion 64 on the upstream side of the air flowing through the outdoor heat exchanger 8 of the support bracket 52 (having the same configuration as the support bracket 51) exchanges heat with the housing 20 The chamber side front side plate 24 and the supported portion 65 on the downstream side are respectively fixed to the windproof plate 35.

  Thus, the support brackets 51 and 52 have a role of blocking the passage of air at a portion of the outdoor heat exchanger 8 where the fins 44 are not attached (thereby improving the heat exchange efficiency of the outdoor heat exchanger 8) ) And the role of fixing the outdoor heat exchanger 8 to the housing 20 of the outdoor unit 1 are respectively used in one part, and the number of parts can be reduced.

However, if the support brackets 51 and 52 are made of aluminum and are not insulated from the housing 20 made of steel or the like of the outdoor unit 1, there is a problem that the corrosion easily proceeds.
So, below, a means which can control corrosion of support brackets 51 and 52 is explained.
The support bracket 52 (provided with the supported portions 64 and 65 and has the same configuration as the support bracket 51) on the heat exchange chamber 31 side is also provided with a means capable of suppressing the same corrosion as the support bracket 51. In the following, the support bracket 51 will be described as a representative.

  It is the fixing member 70 that realizes the means for suppressing such corrosion, and the fixing member 70 will be described in detail below. As shown in FIG. 5, the fixing member 70 is provided, for example, at the legs, top, and middle positions of the supported portions 61 and 62, for example. The fixing member 70 includes an insulating portion made of an insulating material (for example, a resin material), and serves as a fixing position for fixing the support bracket 51 to the housing 20.

FIG. 6 is a plan view of relevant parts showing the fixing portion between the support bracket 51 and the housing 20. As shown in FIG. As shown in the figure, the supported portion 61 on the upstream side of the air and the machine room rear side plate 23 of the housing 20 are fixed by screws 38 via the fixing members 70. Further, the downstream supported portion 62 and the partition plate 26 are fixed by the screw 38 via the fixing member 70.
FIG. 7 (a) is a front view of a portion of the fixing member 70 provided on the support bracket 51, and FIG. 7 (b) is a side view thereof. 8 (a) is a front view of the fixing member 70, FIG. 8 (b) is a left side view of FIG. 8 (a), FIG. 8 (c) is a right side view, and FIG. 8 (d) is a top view. is there. FIG. 9 is an exploded view of the mounting structure of the fixing member 70 to the supported portion 61. As shown in FIG.

  As mainly shown in FIG. 8A, the fixing member 70 is, for example, a rectangular plate-like member when viewed from the front, and is a first fixing portion functioning as an insulating portion formed of an insulating material such as resin. It has 71. In the first fixing portion 71, a concave groove 75 in which the central portion of the plate thickness is concaved is formed on the upper surface, the right side surface, and the lower surface. Also, a rectangular pocket-like recess 74 is formed further inside the recess 75 with the left side surface as the opening 74 a. Furthermore, the screw hole 72 penetrates from the front surface to the back surface of the first fixing portion 71 corresponding to the position where the concave portion 74 exists.

The concave portion 74 has a rectangular plate shape corresponding to the rectangular pocket shape, and a second fixing portion 36 made of metal, for example, steel is accommodated from the opening 74a. A screw hole 37 passes through, for example, a central portion of the second fixing portion 36, and when the second fixing portion 36 is stored in the recess 74, the positions of the screw hole 72 and the screw hole 37 are aligned.
When the fixing member 70 is attached to the supported portion 61 (the supported portion 62 is also the same), the second fixing portion 36 is accommodated in the concave portion 74 of the first fixing portion 71, and the fixing member 70 is completed (previously Complete and prepare).

  And as shown in FIG. 9, the rectangular notch 66 is formed in the front-end | tip part side of the to-be-supported part 61, and the shape of the edge of the inner periphery in this notch 66 is a shape of the ditch | groove 75 Fit. Therefore, the fixing member 70 can be attached to the supported portion 61 by engaging the recessed groove 75 with the end edge portion of the inner periphery of the notch 66. The screw 38 passes through the notch 66 when screwing in the manner described above with the screw 38 (see FIG. 6). The attachment position of the fixing member 70 to the supported portion 61 is a position at which the screw is fixed to the machine room side rear plate 23 and the partition plate 26 (a screw hole is formed in the machine room rear side plate 23 and the partition plate 26) It is. When the housing 20 and the supported portions 61 and 62 are screwed and fixed as described above, the second fixing portion 36 and the support bracket 51 are insulated by the first fixing portion 71. The shape of the fixing member 70 is not limited to a rectangular shape, and may be various shapes. The same applies to the shape of the concave groove 75 of the fixing member 70 and the second fixing portion 36 (recess 74).

  As described above, the fixing members 70 are provided at a plurality of locations in the height direction of the supported portions 61 and 62. And, as shown in FIGS. 7 and 5, between the upper and lower fixing members 70, 70, an auxiliary member which protrudes in the same direction as the fixing member 70 extending to the side of the supported portions 61, 62. 39 are provided. The auxiliary member 39 is made of resin or other insulating material, and is provided by adhesion or other means. The auxiliary member 39 is preferably projected to the side of the supported portions 61 and 62 as much as the fixing member 70. Alternatively, the auxiliary member 39 may be a part of the supported portions 61 and 62.

According to the present embodiment described above, the fixing member 70 includes the insulating portion (first fixing portion 71) that insulates the support bracket 51 and the housing 20 of the outdoor unit 1, and the fixing member 70 connects to the housing 20. The fixed position of the support bracket 51 can prevent the support bracket 51 from being corroded.
The fixing member 70 includes a second fixing portion 36, and the second fixing portion 36 fixes the support bracket 51 to the housing 20 by screwing. Then, since the second fixed portion 36 is not in contact with the support bracket 51 even when screwing and fixing, the second fixed portion 36 can prevent the support bracket 51 from being corroded.

Since the fixing member 70 is attached to the notch 66 of the supported portions 61 and 62, the fixing member 70 can be made not to protrude too much from the supported portions 61 and 62. The mounting structure to the housing can be made compact.
Since the auxiliary members 39 are provided in the supported portions 61 and 62, it is difficult to form a gap between the fixing members 70 and 70, and it is possible to suppress the air from entering the support bracket 51, and the heat of the outdoor heat exchanger 8. Exchange efficiency can be improved.

Modification of First Embodiment
In this modification, the same reference numerals are used for the members and the like common to those of the first embodiment, and the detailed description is omitted. 10 (a) is a front view of the fixing member 70, FIG. 10 (b) is a left side view of FIG. 10 (a), FIG. 10 (c) is a right side view, and FIG. 10 (d) is a top view. is there. This modification is different from the first embodiment in that the screw hole 72 formed in the first fixing portion 71 does not penetrate the fixing member 70 and the tip of the screw 38 (FIG. 6) is in the middle of the fixing member 70 To stay. In the example of FIG. 10, the tip end portion 72 a of the screw hole 72 remains in the middle of the first fixing portion 71. Alternatively, the screw hole 72 may be retained at the second fixing portion 36 (FIG. 9).

  In this manner, when the fixing member 70 is screwed to the housing 20, the screw hole 72 does not penetrate the fixing member 70 and the tip end of the screw 38 (FIG. 6) stays inside the fixing member 70. The iron powder generated from the inside of the member 70 from the second fixing portion 36 (FIG. 9) and the screw 38 (FIG. 6) does not fly out. These iron powders fall on the support bracket 51 and cause corrosion, so that the corrosion of the support bracket 51 can be prevented.

Example 2
Example 2 will be described. The same reference numerals as in the first embodiment denote the same members in the second embodiment, and a detailed description thereof will be omitted.
In the example of FIG. 5 of the first embodiment, the portions 61a and 62a of the supported portions 61 and 62 are exposed at the lowermost portion of the fixing member 70, so the portion 61a is at the bottom (bottom plate 21) of the housing 20 of the outdoor unit 1. , 62a come into contact with each other, causing corrosion of the support bracket 51. In order to prevent that, an extra member for preventing insulation is required.
Therefore, in place of the fixing member 70, a fixing member 80 shown in FIG. 11 (a) is a front view of the fixing member 80, FIG. 11 (b) is a left side view of FIG. 11 (a), FIG. 11 (c) is a right side view, and FIG. 11 (d) is a top view. is there.

  The fixing member 80 is a rectangular plate-like member when viewed from the front, and includes a first fixing portion 81 that functions as an insulating portion formed of an insulating material such as resin. In the first fixing portion 81, a concave groove 85 in which the central portion of the plate thickness is concaved is formed on the upper surface and the right side surface. In addition, a rectangular pocket-shaped recess 84 is formed further inside the recessed groove 85 with the left side surface as the opening 84 a. Furthermore, the screw hole 82 penetrates from the front surface to the back surface of the first fixing portion 81 corresponding to the existing position of the concave portion 84 (may not penetrate as in the modification of the first embodiment).

  The recess 84 has a rectangular plate shape corresponding to the rectangular pocket shape, and a second fixing portion 36 (FIG. 9) made of metal, for example, steel, is accommodated from the opening 84a. The screw hole 37 (FIG. 9) passes through, for example, the central portion of the second fixing portion 36, and when the second fixing portion 36 is accommodated in the recess 84, the screw hole 82 and the screw hole 37 (FIG. 9) The position of is correct.

The fixing member 80 differs from the fixing member 70 in that the concave groove 85 is not formed on the lower side of the first fixing portion 81, and the entire bottom portion of the fixing member 80 is a part of the first fixing portion 81. It is the point which has made the bottom part 83 to make.
When the fixing member 80 is attached to the supported portion 61 (same as the supported portion 62), the second fixing portion 36 is accommodated in the recess 84 of the first fixing portion 81, and the fixing member 80 is completed (completed in advance Let me prepare it).

As shown in FIG. 12, a rectangular notch 67 is formed at the lowermost end of the supported portions 61 and 62, and the shape of the edge of the inner periphery of the notch 67 is the shape of the concave groove 85. Fit. Therefore, the fixing member 80 can be attached to the supported portions 61 and 62 by engaging the recessed groove 85 with the end edge portion of the inner periphery of the notch 67. When the screw 38 (FIG. 6) is screwed and fixed as in the case of the fixing member 70, the screw 38 is inserted through the notch 67.
13A is a plan view of the lower end portion of the support bracket 51 when the fixing member 80 is attached to the supported portions 61 and 62, and FIG. 13B is a right side view thereof.

As apparent from FIG. 13, the lower end portion of the support bracket contacts the casing 20 of the outdoor unit 1 through the bottom portion 83 of the fixing member 80, so the support bracket 51 is less likely to be corroded.
At this time, the support bracket 51 is raised by the amount of the bottom portion 83, and as shown in FIG. 13A, the space 89 is empty below the support bracket 51, and becomes an air passage. Therefore, it is desirable to provide a spacer or the like in the space 89 to close the space 89 and enhance the heat exchange efficiency of the outdoor heat exchanger 8.

[Example 3]
Example 3 will be described. The same reference numerals as in the first embodiment denote the same members in the second embodiment, and a detailed description thereof will be omitted.
The difference between this embodiment and the first and second embodiments is that a single fixing member 90 used instead of the fixing member 70 is attached to the lower ends of both the supported portion 61 and the supported portion 62. .
FIG. 14 (a) is a plan view of the lower end portion of the support bracket 51 when the fixing member 90 is attached to the supported portions 61, 62, and FIG. 14 (b) is a right side view thereof.

Fig.15 (a) is a front view of the 1st fixing | fixed part 91 in the fixing member 90, FIG.15 (b) is a left view of Fig.15 (a), FIG.15 (c) is the top view. The fixing member 90 has a first fixing portion 91 that functions as an insulating portion. The first fixing portion 91 includes a bottom plate 96 having a width from the supported portions 61 to 62, including a storage portion 94 described later. Side plates 97 rise from both sides of the bottom plate 96, respectively. A storage portion 94 for storing the second fixing portion 36 (FIG. 12) is formed on the inner side surface of the side surface plate 97. The upper outline of the L-shaped convex member 95 (projecting to the inside of the first fixing portion 91) which forms the storage portion 94 and protrudes from the side plate 97 into the fixing member 90 is the notch 67 (FIG. 12) Match the edge of the The housing portion 94 is not pocket-like, and no wall is present inside the fixing member 90. The inlet 94a serves as an inlet for housing the second fixed portion 36 (FIG. 12). The second fixing portion 36 (FIG. 12) is supported by the inner periphery of the convex member 95. Screw holes 92 are formed in each side plate 97. The screw holes 92 are aligned with the screw holes 37 when the second fixing portion 36 (FIG. 12) is stored in the storage portion 94 (the state in which the second fixing portion 36 is stored in the storage portion 94 is shown in FIG. Not shown). The screw hole 92 may be present halfway through the second fixing portion 36 and may not penetrate through the first fixing portion 91 and the second fixing portion 36. The screw 38 (FIG. 6) passes through the notch 67 and does not contact the supported portions 61 and 62.

The second fixing portion 36 (FIG. 12) is attached to such a first fixing portion 91, the lower end side of the support bracket 51 is inserted into the first fixing portion 91, and the notches 67 of the supported portions 61 and 62. The fixing member 90 can be attached to the support bracket 51 by supporting (FIG. 12) with the upper outline of the convex member 95. Thus, the fixing member 90 covers the entire bottom surface of the support bracket 51.
Unlike the first and second embodiments, the fixing member 90 is not configured to be sandwiched by the first fixing portion 91 from both sides of the supported portion 61 and the supported portion 62, but the supported portion 61 and the supported portion 62. The side plates 97 project outward from each other.
As described above, since the fixing member 90 is single and attached to the lower ends of both the supported portion 61 and the supported portion 62, the mounting operation can be facilitated.

In addition, since the bottom plate 96 forming a part of the first fixing portion 91 can be in contact with the housing 20 of the outdoor unit 1, corrosion of the support bracket 51 can be prevented.
Furthermore, as compared with the cases of the first and second embodiments, the contact area between the bottom surface of the support bracket 51 and the fixing member 90 is increased, whereby the stability when installing the outdoor heat exchanger 8 is increased.
Furthermore, by covering the entire bottom surface of the support bracket 51, the gap between the support bracket 51 and the fixing member 90 disappears, and air can be prevented from entering the inside of the support bracket 51.

Modification of Embodiment 3
In this modification, the same reference numerals are used for members and the like common to those of the third embodiment, and the detailed description will be omitted.
16 (a) is a front view of the first fixing portion 91 of the fixing member 90, FIG. 16 (b) is a left side view of FIG. 16 (a), and FIG. 16 (c) is a top view.

The difference between this modification and the third embodiment is that, as shown in FIG. 16A, the flat portion 93 for supporting the entire bottom surface of the support bracket 51 is the same as the bottom surface of the support bracket 51 on the top surface of the bottom plate 96. The inner side of the flat portion 93 is an inclined surface 98 which is inclined downward toward the U-shaped opening (outside of the support bracket 51).
As described above, since the inclined surface 98 which is inclined downward toward the outside of the support bracket 51 is provided on the upper surface of the bottom plate 96, rainwater etc. is not easily accumulated in the bottom plate 96, and the support bracket 51 is less likely to corrode. Can.
