ところで、室外機を組み立てる過程では、作業者が室外機のケーシングに熱交換器を設置するのが通常である。このため、ケーシングの底板に対する熱交換器の設置位置は、室外機毎に多少異なる。また、平坦な熱交換器に曲げ加工を施すことによって内側熱交換部を形成する場合は、スプリングバック現象が生じるため、熱交換器毎に形状が若干異なるのが通常である。このように、ケーシングに対する熱交換器の設置位置や、熱交換器自体の形状には、多少の誤差がある。このため、互いに向かい合う内側熱交換部の間隔は、設計値と多少異なるのが通常である。   By the way, in the process of assembling the outdoor unit, it is normal for an operator to install a heat exchanger in the casing of the outdoor unit. For this reason, the installation position of the heat exchanger with respect to the bottom plate of the casing is slightly different for each outdoor unit. Further, when the inner heat exchanging portion is formed by bending a flat heat exchanger, a springback phenomenon occurs, and therefore the shape is usually slightly different for each heat exchanger. Thus, there are some errors in the installation position of the heat exchanger with respect to the casing and the shape of the heat exchanger itself. For this reason, the interval between the inner heat exchange portions facing each other is usually slightly different from the design value.

一方、特許文献1のセンターピラーは、横断面がU字状の柱状に形成され、互いに向かい合う内側熱交換部の間に入り込むことによって、内側熱交換部同士の間隔を維持する。このため、内側熱交換部同士の間隔が設計値よりも狭い場合は、センターピラーが内側熱交換部の間に入り込み、向かい合う内側熱交換部を押し広げることによって内側熱交換部同士の間隔を維持できる。しかし、内側熱交換部同士の間隔が設計値よりも広い場合は、センターピラーによって向かい合う内側熱交換部同士を近づけることができないため、内側熱交換部同士の間隔を維持するのが困難である。   On the other hand, the center pillar of Patent Document 1 is formed in a columnar shape with a U-shaped cross section, and maintains the interval between the inner heat exchange parts by entering between the inner heat exchange parts facing each other. For this reason, when the distance between the inner heat exchange parts is narrower than the design value, the center pillar enters between the inner heat exchange parts and pushes the inner heat exchange parts facing each other to maintain the distance between the inner heat exchange parts. it can. However, when the distance between the inner heat exchange parts is wider than the design value, it is difficult to maintain the distance between the inner heat exchange parts because the inner heat exchange parts facing each other by the center pillar cannot be brought close to each other.

本開示の目的は、それぞれの内側熱交換部が向かい合うように熱交換器が配置された室外機において、向かい合う内側熱交換部同士の間隔を保持することにある。   The objective of this indication is in the outdoor unit in which the heat exchanger was arrange | positioned so that each inner heat exchange part may face, and maintaining the space | interval of the inner heat exchange parts which faced each other.

本開示の第6の態様は、上記第5の態様において、上記先端仕切板(80)は、一対の側壁部(83)を有する溝型に形成され、上記先端仕切板(80)の各側壁部(83)には、該側壁部(83)同士の間隔が上記内側熱交換部(42,52)の先端側から上記外周熱交換部(41,51)側へ向かって次第に短くなるように傾斜した傾斜部(84)が形成されるものである。   According to a sixth aspect of the present disclosure, in the fifth aspect, the tip partition plate (80) is formed in a groove shape having a pair of side wall portions (83), and each sidewall of the tip partition plate (80). In the portion (83), the interval between the side wall portions (83) is gradually shortened from the front end side of the inner heat exchange portion (42, 52) toward the outer peripheral heat exchange portion (41, 51) side. An inclined part (84) is formed.

第6の態様では、溝型に形成された先端仕切板(80)は、各側壁部(83)に傾斜部(84)が形成され、傾斜部(84)同士の間隔が内側熱交換部(42,52)の先端側から外周熱交換部(41,51)側へ向かって次第に狭くなる。このため、内側熱交換部(42,52)の先端部同士の間隔が設計値と多少異なっても、先端仕切板(80)の傾斜部(84)が内側熱交換部(42,52)の先端部同士の間に容易に入り込み、内側熱交換部(42,52)の先端部同士の間が先端仕切板(80)によって塞がれる。従って、この態様によれば、内側熱交換部(42,52)の先端部同士の間隔が設計値と多少異なっていても、互いに向かい合う内側熱交換部(42,52)の間を塞ぎ、熱交換器(40,50)をバイパスする空気の流れを阻止できる。   In the sixth aspect, the tip partition plate (80) formed in the groove shape is formed with an inclined portion (84) on each side wall portion (83), and the interval between the inclined portions (84) is the inner heat exchange portion ( 42, 52) gradually becomes narrower from the front end side toward the outer peripheral heat exchange section (41, 51) side. For this reason, even if the space | interval of the front-end | tip parts of an inner side heat exchange part (42,52) is a little different from a design value, the inclination part (84) of a front-end | tip partition plate (80) It easily enters between the tip portions, and the tip portions of the inner heat exchange portions (42, 52) are closed by the tip partition plate (80). Therefore, according to this aspect, even if the distance between the tip portions of the inner heat exchanging portions (42, 52) is slightly different from the design value, the gap between the inner heat exchanging portions (42, 52) facing each other is blocked. Air flow bypassing the exchanger (40, 50) can be blocked.

A deformable sealing material (86) is provided.

第7の態様では、先端仕切板(80)にシール材(86)が設けられ、このシール材(86)が各熱交換器(40,50)の内側熱交換部(42,52)の先端部に当たって変形する。このため、先端仕切板(80)と各内側熱交換部(42,52)の隙間がシール材(86)によってシールされ、その結果、熱交換器(40,50)をバイパスする空気の流量を低減できる。   In the seventh aspect, a sealing material (86) is provided on the tip partition plate (80), and this sealing material (86) is the tip of the inner heat exchanging portion (42, 52) of each heat exchanger (40, 50). It hits the part and deforms. For this reason, the gap between the tip partition plate (80) and each inner heat exchange section (42, 52) is sealed by the sealing material (86). As a result, the flow rate of air bypassing the heat exchanger (40, 50) is reduced. Can be reduced.

本開示の第8の態様は、上記第5〜第7のいずれか一つの態様において、上記先端仕切板(80)は、その上端部が上記間隔保持部材(60)に連結されるものである。   In an eighth aspect of the present disclosure, in any one of the fifth to seventh aspects, the tip partition plate (80) has an upper end connected to the spacing member (60). .

第8の態様では、先端仕切板(80)の上端部が間隔保持部材(60)に連結される。つまり、この態様では、間隔保持部材(60)が、先端仕切板(80)を固定するための部材を兼ねる。   In the eighth aspect, the upper end portion of the tip partition plate (80) is coupled to the spacing member (60). That is, in this aspect, the spacing member (60) also serves as a member for fixing the tip partition plate (80).

本実施形態では、各熱交換器(40,50)に複数の熱交換列部(43,45,53,55)が設けられる。上端仕切板(60)の第1保持部(70)には、それに対応する第1熱交換器(40)の全ての熱交換列部(43,45)が嵌り込む。また、上端仕切板(60)の第2保持部(75)には、それに対応する第2熱交換器(50)の全ての熱交換列部(53,55)が嵌り込む。このため、上端仕切板(60)の各保持部(70,75)によって、熱交換器(40,50)に設けられた複数の熱交換列部(43,45,53,55)同士の間隔を保持することが可能となる。   In this embodiment, each heat exchanger (40, 50) is provided with a plurality of heat exchange rows (43, 45, 53, 55). All the heat exchange row parts (43, 45) of the first heat exchanger (40) corresponding to the first holding part (70) of the upper end partition plate (60) are fitted. Moreover, all the heat exchange row | line | column parts (53,55) of the 2nd heat exchanger (50) corresponding to it fit in the 2nd holding | maintenance part (75) of an upper end partition plate (60). For this reason, the space | interval of several heat exchange row | line | column parts (43,45,53,55) provided in the heat exchanger (40,50) by each holding | maintenance part (70,75) of an upper end partition plate (60). Can be held.

ここで、上述したように、各熱交換器(40,50)は、平板状に形成された半製品を塑性変形させることによって、U字状に形成される。そのため、外周熱交換部(41,51)に対する内側熱交換列部(45,55)の角度や、外側熱交換列部(43,53)と内側熱交換列部(45,55)の間隔は、熱交換器(40,50)毎に多少ばらつくのが通常である。   Here, as described above, each heat exchanger (40, 50) is formed in a U shape by plastically deforming a semi-finished product formed in a flat plate shape. Therefore, the angle of the inner heat exchange row (45,55) relative to the outer heat exchange portion (41,51) and the distance between the outer heat exchange row (43,53) and the inner heat exchange row (45,55) are Usually, the heat exchanger (40, 50) varies somewhat.

一方、上端仕切板(60)の各保持部(70,75)において、内面側板部(72,77)は、概ね鉛直下方へ向かって延びる一方、外面側板部(73,78)は、下方へ向かうにつれて内面側板部(72,77)から離れる方向に傾斜している(図5を参照)。つまり、各保持部(70,75)では、内面側板部(72,77)と外面側板部(73,78)の間隔が、下方へ向かうにつれて広がっている。このため、外側熱交換列部(43,53)と内側熱交換列部(45,55)の間隔が熱交換器(40,50)毎に多少異なっていても、内側熱交換列部(45,55)の上部に上端仕切板(60)の保持部(70,75)を容易に嵌め込むことが可能となる。   On the other hand, in each holding portion (70, 75) of the upper end partition plate (60), the inner surface side plate portion (72, 77) extends substantially vertically downward, while the outer surface side plate portion (73, 78) extends downward. As it goes, it inclines in the direction away from the inner surface side plate portions (72, 77) (see FIG. 5). That is, in each holding | maintenance part (70,75), the space | interval of an inner surface side board part (72,77) and an outer surface side board part (73,78) is expanded as it goes below. For this reason, even if the space | interval of an outer side heat exchange row | line | column part (43,53) and an inner side heat exchange row | line | column part (45,55) differs a little for every heat exchanger (40,50), an inner side heat exchange row | line | column part (45 , 55) can be easily fitted into the holding portion (70, 75) of the upper end partition plate (60).

また、上端仕切板(60)の各保持部(70,75)において、内面側板部(72,77)と外面側板部(73,78)の間隔は、上方(即ち、本体板部(62)側)へ向かって次第に狭くなっている。このため、上端仕切板(60)を取り付ける前の状態で外側熱交換列部(43,53)と内側熱交換列部(45,55)の間隔が設計値よりも広い場合であっても、内側熱交換部(42,52)を内面側板部(72,77)と外面側板部(73,78)の間に嵌め込むことによって、外側熱交換列部(43,53)と内側熱交換列部(45,55)の間隔を狭めて設計値に近づけることが可能となる。   Further, in each holding portion (70, 75) of the upper partition plate (60), the interval between the inner surface side plate portion (72, 77) and the outer surface side plate portion (73, 78) is upward (that is, the main body plate portion (62). Side). For this reason, even when the interval between the outer heat exchange row part (43, 53) and the inner heat exchange row part (45, 55) is wider than the design value in the state before attaching the upper end partition plate (60), By fitting the inner heat exchange part (42,52) between the inner surface side plate part (72,77) and the outer surface side plate part (73,78), the outer heat exchange line part (43,53) and the inner heat exchange line It is possible to reduce the interval between the parts (45, 55) to approach the design value.

ここで、本実施形態の室外機(1)では、平面視でU字状に形成された各熱交換器(40,50)の内側に圧縮機(31)等の構成機器が配置されており(図2を参照)、各熱交換器(40,50)とその内側に配置された機器との接触を防ぐ必要がある。そのためには、各熱交換器(40,50)の内側熱交換列部(45,55)の内面を、他の構成機器から離れた位置に設ける必要がある。   Here, in the outdoor unit (1) of this embodiment, components such as the compressor (31) are arranged inside each heat exchanger (40, 50) formed in a U shape in plan view. (See FIG. 2), it is necessary to prevent contact between the heat exchangers (40, 50) and the devices arranged inside them. For this purpose, it is necessary to provide the inner surface of the inner heat exchange row portion (45, 55) of each heat exchanger (40, 50) at a position away from other components.

一方、上端仕切板(60)の各保持部(70,75)では、内面側板部(72,77)が本体板部(62)から概ね鉛直下方へ向かって延びている。このため、内側熱交換列部(45,55)が内面側板部(72,77)に当たることによって、内側熱交換列部(45,55)の内面の位置を正確に規定することが可能となる。従って、本実施形態によれば、熱交換器(40,50)と他の構成機器との接触を未然に防止できる。   On the other hand, in each holding portion (70, 75) of the upper end partition plate (60), the inner surface side plate portion (72, 77) extends substantially vertically downward from the main body plate portion (62). For this reason, when the inner side heat exchange row | line | column part (45,55) hits an inner surface side board | plate part (72,77), it becomes possible to prescribe | regulate the position of the inner surface of an inner side heat exchange row | line | column part (45,55) correctly. . Therefore, according to the present embodiment, contact between the heat exchanger (40, 50) and other components can be prevented in advance.

また、本実施形態の室外機(1)において、各熱交換器(40,50)は、内側熱交換部(42,52)の外周熱交換部(41,51)とは逆側に位置する先端が、熱交換器(40,50)の側端となる。室外機(1)は、各内側熱交換部(42,52)の上端から下端に亘って設けられて、内側熱交換部(42,52)の間の空間を内側熱交換部(42,52)の先端側で塞ぐ先端仕切板(80)を備える。   Moreover, in the outdoor unit (1) of this embodiment, each heat exchanger (40,50) is located on the opposite side to the outer periphery heat exchange part (41,51) of an inner side heat exchange part (42,52). The tip is the side end of the heat exchanger (40, 50). The outdoor unit (1) is provided from the upper end to the lower end of each inner heat exchange part (42,52), and the space between the inner heat exchange parts (42,52) is defined as the inner heat exchange part (42,52). ) Is provided with a front end partition plate (80) that is closed at the front end side.

本実施形態では、各熱交換器(40,50)の内側熱交換部(42,52)の間に先端仕切板(80)が配置される。先端仕切板(80)は、二つの内側熱交換部(42,52)の間に形成された導風通路(27)を、内側熱交換部(42,52)の先端側で塞ぐ。このため、内側熱交換部(42,52)の先端部同士の間を通って熱交換器(40,50)をバイパスする空気の流れが抑制される。   In this embodiment, a front-end | tip partition plate (80) is arrange | positioned between the inner side heat exchange parts (42,52) of each heat exchanger (40,50). The tip partition plate (80) closes the air guide passage (27) formed between the two inner heat exchange parts (42, 52) on the tip side of the inner heat exchange part (42, 52). For this reason, the flow of the air which passes between the front-end | tip parts of an inner side heat exchange part (42,52) and bypasses a heat exchanger (40,50) is suppressed.

また、本実施形態の室外機(1)において、先端仕切板(80)は、一対の側壁部(83)を有する溝型に形成される。先端仕切板(80)の各側壁部(83)には、側壁部(83)同士の間隔が内側熱交換部(42,52)の先端側から外周熱交換部(41,51)側へ向かって次第に短くなるように傾斜した傾斜部(84)が形成される。   Moreover, in the outdoor unit (1) of this embodiment, the front-end | tip partition plate (80) is formed in the groove type which has a pair of side wall part (83). In each side wall part (83) of the front end partition plate (80), the distance between the side wall parts (83) is from the front end side of the inner heat exchange part (42,52) to the outer side heat exchange part (41,51) side. Thus, an inclined portion (84) inclined so as to be gradually shortened is formed.

本実施形態において、溝型に形成された先端仕切板(80)は、各側壁部(83)に傾斜部(84)が形成され、傾斜部(84)同士の間隔が内側熱交換部(42,52)の先端側から外周熱交換部(41,51)側へ向かって次第に狭くなる。このため、内側熱交換部(42,52)の先端部同士の間隔が設計値と多少異なっていても、先端仕切板(80)の傾斜部(84)が内側熱交換部(42,52)の先端部同士の間に容易に入り込み、内側熱交換部(42,52)の先端部同士の間が先端仕切板(80)によって塞がれる。従って、本実施形態によれば、内側熱交換部(42,52)の先端部同士の間隔が設計値と多少異なっていても、互いに向かい合う内側熱交換部(42,52)の間を塞ぎ、熱交換器(40,50)をバイパスする空気の流れを阻止できる。   In the present embodiment, the front partition plate (80) formed in the groove shape is formed with inclined portions (84) on each side wall portion (83), and the interval between the inclined portions (84) is the inner heat exchange portion (42). , 52) is gradually narrowed from the front end side toward the outer peripheral heat exchange section (41, 51) side. For this reason, even if the space | interval of the front-end | tip parts of an inner side heat exchange part (42,52) is a little different from a design value, the inclination part (84) of a front-end | tip partition plate (80) is the inner side heat exchange part (42,52) The front end portions of the inner heat exchange portions (42, 52) are blocked by the front end partition plate (80). Therefore, according to the present embodiment, even if the distance between the tips of the inner heat exchange parts (42, 52) is slightly different from the design value, the gap between the inner heat exchange parts (42, 52) facing each other is closed. Air flow bypassing the heat exchanger (40, 50) can be blocked.

また、本実施形態の室外機(1)において、先端仕切板(80)の傾斜部(84)の外側面には、内側熱交換部(42,52)の先端部に当たって変形するシール材(86)が設けられる。   Further, in the outdoor unit (1) of the present embodiment, the outer surface of the inclined portion (84) of the tip partition plate (80) is contacted with the tip of the inner heat exchanging portion (42, 52) and is deformed (86 ) Is provided.

本実施形態において、先端仕切板(80)を所定の位置に設置すると、シール材(86)が各熱交換器(40,50)の内側熱交換部(42,52)の先端部に当たって変形する。このため、先端仕切板(80)と各内側熱交換部(42,52)の隙間がシール材(86)によってシールされ、その結果、熱交換器(40,50)をバイパスする空気の流量を低減できる。   In this embodiment, when the tip partition plate (80) is installed at a predetermined position, the sealing material (86) hits the tip of the inner heat exchanging portion (42, 52) of each heat exchanger (40, 50) and is deformed. . For this reason, the gap between the tip partition plate (80) and each inner heat exchange section (42, 52) is sealed by the sealing material (86). As a result, the flow rate of air bypassing the heat exchanger (40, 50) is reduced. Can be reduced.

また、本実施形態の室外機(1)では、先端仕切板(80)は、その上端部が上端仕切板(60)に連結される。   Moreover, in the outdoor unit (1) of this embodiment, the upper end part of the tip partition plate (80) is connected to the upper end partition plate (60).

本実施形態の室外機(1)では、先端仕切板(80)の上端部が上端仕切板(60)に連結される。つまり、本実施形態では、上端仕切板(60)が、先端仕切板(80)を固定するための部材を兼ねる。   In the outdoor unit (1) of the present embodiment, the upper end portion of the tip partition plate (80) is connected to the upper end partition plate (60). That is, in this embodiment, the upper end partition plate (60) also serves as a member for fixing the front end partition plate (80).
