Description

空気調和装置Air conditioner
　本発明は、上下方向に並列させた複数の分割熱交換器を有する熱交換器を備えた空気調和装置に関するものである。 The present invention relates to an air conditioner including a heat exchanger having a plurality of divided heat exchangers arranged in parallel in the vertical direction.
　従来、空気調和装置は、上下方向に並列させた複数の分割熱交換器を有する熱交換器を備えた構成が知られている。熱交換器は、間隔をあけて並列に配置された複数のフィンと、フィンを貫通して接続された伝熱管と、を有している。熱交換器は、蒸発器として機能する場合に、冷媒の蒸発温度が周囲の空気温度に比べて低くなるため、空気中の水分がフィンの表面に結露する。熱交換器は、結露水が伝熱管又はフィンの間に滞留すると、該結露水が通風抵抗となり、熱交換効率が低下するおそれがある。また、熱交換器は、滞留した結露水が凍ると伝熱管を圧し潰して、冷媒漏れを引き起こすおそれもある。そのため、熱交換器は、発生した結露水を下方へ誘導して速やかに排水させる必要がある。 Conventionally, it is known that an air conditioner is provided with a heat exchanger having a plurality of divided heat exchangers arranged in parallel in the vertical direction. The heat exchanger has a plurality of fins arranged in parallel at intervals and a heat transfer tube connected through the fins. When the heat exchanger functions as an evaporator, the evaporation temperature of the refrigerant is lower than the ambient air temperature, so that moisture in the air condenses on the surface of the fins. In the heat exchanger, if the condensed water stays between the heat transfer tubes or the fins, the condensed water becomes ventilation resistance, and the heat exchange efficiency may decrease. Further, the heat exchanger may crush the heat transfer tube when the accumulated condensed water freezes, causing a refrigerant leak. Therefore, the heat exchanger needs to guide the generated condensed water downward and drain it promptly.
　例えば特許文献１に開示された空気調和装置は、上下方向に並列させた上部熱交換器と下部熱交換器との間に、上部熱交換器で発生した結露水を受け止めて貯留する補助ドレンパンが設けられた構成である。補助ドレンパンには、貯留した結露水を外部に排水するための切り欠きが形成されている。また、上部熱交換器と下部熱交換器の左右方向の両端には、補助ドレンパンから排水された結露水を下部熱交換器へ誘導する側板が設けられている。 For example, the air conditioner disclosed in Patent Document 1 has an auxiliary drain pan that receives and stores dew condensation water generated in the upper heat exchanger between the upper heat exchanger and the lower heat exchanger arranged in parallel in the vertical direction. It is a provided configuration. The auxiliary drain pan is formed with a notch for draining the stored condensed water to the outside.

　特許文献１の空気調和装置では、上部熱交換器で発生した結露水を補助ドレンパンで受けることができるが、該結露水を補助ドレンパンへ誘導できる構成ではない。そのため、この空気調和装置は、結露水が上部熱交換器のフィンの分割した端面又伝熱管に滞留して通風抵抗となり、熱交換効率が低下するおそれがある。また、熱交換器とドレンパンとの間に異物が堆積して排水性が低下するおそれもある。 In the air conditioner of Patent Document 1, the dew condensation water generated in the upper heat exchanger can be received by the auxiliary drain pan, but the dew condensation water cannot be guided to the auxiliary drain pan. Therefore, in this air conditioner, dew condensation water may stay on the divided end faces or heat transfer tubes of the fins of the upper heat exchanger to become ventilation resistance, and the heat exchange efficiency may decrease. In addition, foreign matter may accumulate between the heat exchanger and the drain pan, reducing drainage.

　流路切換手段２は、一例として四方弁であり、冷媒の流路を切り換える機能を有するものである。流路切換手段２は、冷房運転時において、圧縮機１の冷媒吐出側と室外側熱交換器３のガス側とを接続するとともに、圧縮機１の冷媒吸入側と室内側熱交換器８のガス側とを接続するように冷媒流路を切り換える。一方、流路切換手段２は、暖房運転時において、圧縮機１の冷媒吐出側と室内側熱交換器８のガス側とを接続するとともに、圧縮機１の冷媒吸入側と室外側熱交換器３のガス側とを接続するように冷媒流路を切り換える。 The flow path switching means 2 is a four-way valve as an example, and has a function of switching the flow path of the refrigerant. The flow path switching means 2 connects the refrigerant discharge side of the compressor 1 and the gas side of the outdoor heat exchanger 3 during the cooling operation, and also connects the refrigerant suction side of the compressor 1 and the indoor heat exchanger 8.

The refrigerant flow path is switched so as to connect to the gas side of 3.
　室外側熱交換器３は、冷房運転時には凝縮器として機能し、圧縮機１から吐出された冷媒と空気との間で熱交換を行わせるものである。また、室外側熱交換器３は、暖房運転時には蒸発器として機能し、第１膨張機構４から流出した冷媒と空気との間で熱交換を行わせるものである。室外側熱交換器３は、室外側送風機７によって室外空気を吸い込み、冷媒との間で熱交換した空気を室外に排出する。 The outdoor heat exchanger 3 functions as a condenser during the cooling operation, and exchanges heat between the refrigerant discharged from the compressor 1 and the air. Further, the outdoor heat exchanger 3 functions as an evaporator during the heating operation, and causes heat exchange between the refrigerant flowing out from the first expansion mechanism 4 and the air. The outdoor heat exchanger 3 sucks outdoor air by the outdoor blower 7 and discharges the air that has exchanged heat with the refrigerant to the outside.
　第１膨張機構４及び第２膨張機構６は、冷媒回路内を流れる冷媒を減圧して膨張させるものであり、一例として開度が可変に制御される電子膨張弁で構成される。 The first expansion mechanism 4 and the second expansion mechanism 6 decompress and expand the refrigerant flowing in the refrigerant circuit, and are composed of an electronic expansion valve whose opening degree is variably controlled as an example.
　冷媒容器５は、例えばレシーバ又はアキュムレータ等である。冷媒容器５は、運転中に余剰となった液冷媒を貯溜する。冷媒容器５は、第１膨張機構４及び第２膨張機構６との間の冷媒配管上に設置されている。 The refrigerant container 5 is, for example, a receiver or an accumulator. The refrigerant container 5 stores excess liquid refrigerant during operation. The refrigerant container 5 is installed on the refrigerant pipe between the first expansion mechanism 4 and the second expansion mechanism 6.
　室内側熱交換器８は、冷房運転時には蒸発器として機能し、第２膨張機構６から流出した冷媒と空気との間で熱交換を行わせるものである。また、室内側熱交換器８は、暖房運転時には凝縮器として機能し、圧縮機１から吐出された冷媒と空気との間で熱交換を行わせるものである。室内側熱交換器８は、室内側送風機９によって室内空気を吸い込み、冷媒との間で熱交換した空気を室内に供給する。 The indoor heat exchanger 8 functions as an evaporator during the cooling operation, and exchanges heat between the refrigerant flowing out from the second expansion mechanism 6 and the air. Further, the indoor heat exchanger 8 functions as a condenser during the heating operation, and causes heat exchange between the refrigerant discharged from the compressor 1 and the air. The indoor heat exchanger 8 sucks indoor air by the indoor blower 9 and supplies the air that has exchanged heat with the refrigerant into the room.
　次に、空気調和装置１００の冷房運転時の動作を説明する。圧縮機１から吐出された高温高圧のガス冷媒は、流路切換手段２を通過して室外側熱交換器３へと流れて空気と熱交換して凝縮液化する。凝縮液化した冷媒は、第１膨張機構４及び第２膨張機構６で減圧され低圧の気液２相冷媒となり、室内側熱交換器８へと流れて空気と熱交換してガス化する。ガス化した冷媒は、流路切換手段２を通過して圧縮機１に吸入される。このとき、室外側送風機７と室内側送風機９で、それぞれの熱交換器に空気を送る。室内側送風機９で送られる空気は、冷やされて室内に吹出され、室内を冷房する。 Next, the operation of the air conditioner 100 during the cooling operation will be described. The high-temperature and high-pressure gas refrigerant discharged from the compressor 1 passes through the flow path switching means 2 and flows to the outdoor heat exchanger 3 to exchange heat with air and form a condensed liquid. The condensed liquefied refrigerant is decompressed by the first expansion mechanism 4 and the second expansion mechanism 6 to become a low-pressure gas-liquid two-phase refrigerant, which flows to the indoor heat exchanger 8 and exchanges heat with air to gasify. The gasified refrigerant passes through the flow path switching means 2 and is sucked into the compressor 1. At this time, the outdoor blower 7 and the indoor blower 9 send air to the respective heat exchangers. The air sent by the indoor blower 9 is cooled and blown into the room to cool the room.
　次に、空気調和装置１００の暖房運転時の動作を説明する。圧縮機１から吐出された高温高圧のガス冷媒は、流路切換手段２を通過して室内側熱交換器８へと流れて空気と熱交換して凝縮液化する。凝縮液化した冷媒は、第１膨張機構４及び第２膨張機構６で減圧され低圧の気液２相冷媒となり、室外側熱交換器３へと流れて空気と熱交換してガス化する。ガス化した冷媒は、流路切換手段２を通過して圧縮機１に吸入される。このとき、室外側送風機７と室内側送風機９で、それぞれの熱交換器に空気を送る。室内側送風機９で送られる空気は、暖められて室内に吹出され、室内を暖房する。 Next, the operation of the air conditioner 100 during the heating operation will be described. The high-temperature and high-pressure gas refrigerant discharged from the compressor 1 passes through the flow path switching means 2 and flows to the indoor heat exchanger 8 to exchange heat with air and form a condensed liquid. The condensed liquefied refrigerant is depressurized by the first expansion mechanism 4 and the second expansion mechanism 6 to become a low-pressure gas-liquid two-phase refrigerant, which flows to the outdoor heat exchanger 3 and exchanges heat with air to gasify. The gasified refrigerant passes through the flow path switching means 2 and is sucked into the compressor 1. At this time, the outdoor blower 7 and the indoor blower 9 send air to the respective heat exchangers. The air sent by the indoor blower 9 is warmed and blown into the room to heat the room.
　次に、図２～図４に基づいて、実施の形態１に係る空気調和装置の室外側熱交換器の構造について説明する。図２は、実施の形態１に係る空気調和装置の室外側熱交換器を示した斜視図である。図３は、実施の形態１に係る空気調和装置の室外側熱交換器の要部を示した縦断面図である。図４は、実施の形態１に係る空気調和装置の室外側熱交換器の要部を風上側から見た拡大図である。 Next, the structure of the outdoor heat exchanger of the air conditioner according to the first embodiment will be described with reference to FIGS. 2 to 4. FIG. 2 is a perspective view showing an outdoor heat exchanger of the air conditioner according to the first embodiment. FIG. 3 is a vertical cross-sectional view showing a main part of the outdoor heat exchanger of the air conditioner according to the first embodiment. FIG. 4 is an enlarged view of a main part of the outdoor heat exchanger of the air conditioner according to the first embodiment as viewed from the windward side.
　室外側熱交換器３は、図２に示すように、風路の風上側と風下側に配置された２列の熱交換部で構成されている。但し、室外側熱交換器３は、１列又は風路の風上側から風下側に向かって３例以上の熱交換部で構成してもよい。室外側熱交換器３は、図２～図４に示すように、上下方向Ｚに並列させた２つの分割熱交換器３Ａ及び３Ｂを有している。分割熱交換器３Ａ及び３Ｂは、板状の面が略平行となるように左右方向Ｙに間隔をあけて並列に配置された複数のフィン３０と、フィン３０を貫通して接続された複数の伝熱管３１と、を有している。室外側熱交換器３には、図２に示すように、伝熱管３１の左右方向Ｙの一端側に取り付けられた側板３２ａと、伝熱管３１の左右方向Ｙの他端側に取り付けられた側板３２ｂとによって、上下の分割熱交換器３Ａ及び３Ｂが連結されている。 As shown in FIG. 2, the outdoor heat exchanger 3 is composed of two rows of heat exchange portions arranged on the leeward side and the leeward side of the air passage. However, the outdoor heat exchanger 3 may be composed of three or more heat exchangers in one row or from the leeward side to the leeward side of the air passage. As shown in FIGS. 2 to 4, the outdoor heat exchanger 3 has two split heat exchangers 3A and 3B arranged in parallel in the vertical direction Z. The split heat exchangers 3A and 3B have a plurality of fins 30 arranged in parallel at intervals in the left-right direction Y so that the plate-shaped surfaces are substantially parallel, and a plurality of fins 30 connected through the fins 30. It has a heat transfer tube 31 and. As shown in FIG. 2, the outdoor heat exchanger 3 has a side plate 32a attached to one end side of the heat transfer tube 31 in the left-right direction Y and a side plate attached to the other end side of the heat transfer tube 31 in the left-right direction Y. The upper and lower split heat exchangers 3A and 3B are connected by 32b.
　フィン３０は、例えばアルミニウム合金等の金属材で形成されており、伝熱管３１に接して伝熱面積を増大させるものである。伝熱管３１は、例えばアルミニウム合金等の金属材で形成されており、内部に冷媒を通す流路が複数形成された扁平管である。伝熱管３１は、上下方向Ｚに間隔をあけて複数配置されている。上下に隣り合う伝熱管３１は、伝熱連結管３３で連結されている。なお、伝熱管３１は、図示した扁平管に限定されず、円管などの他の形態でもよい。 The fin 30 is made of a metal material such as an aluminum alloy, and is in contact with the heat transfer tube 31 to increase the heat transfer area. The heat transfer tube 31 is a flat tube formed of a metal material such as an aluminum alloy and having a plurality of flow paths for passing a refrigerant inside. A plurality of heat transfer tubes 31 are arranged at intervals in the vertical direction Z. The heat transfer tubes 31 adjacent to each other are connected by a heat transfer connecting tube 33. The heat transfer tube 31 is not limited to the flat tube shown in the figure, and may be in another form such as a circular tube.
　図３及び図４に示すように、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０は、結露水Ｃの排水ガイドとして機能する接合部材３５によって連結されている。接合部材３５は、例えばアルミニウム合金等の金属板によって平板状に形成されている。接合部材３５は、通風方向Ｘにおけるフィン３０の風上側に配置され、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０の端部に当接させて、ロウ付けにより接合されている。 As shown in FIGS. 3 and 4, the fins 30 of the vertically adjacent split heat exchangers 3A and 3B are connected by a joining member 35 that functions as a drainage guide for the condensed water C. The joining member 35 is formed in a flat plate shape by, for example, a metal plate such as an aluminum alloy. The joining member 35 is arranged on the windward side of the fins 30 in the ventilation direction X, is brought into contact with the ends of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B, and is joined by brazing.
　接合部材３５は、図４に示すように、フィン３０の並列方向（左右方向Ｙ）に沿って延びるように形成されている。接合部材３５は、一枚の金属板で構成してもよいし、複数枚に分割され、フィン３０の並列方向（左右方向Ｙ）に沿って配置した構成でもよい。また、室外側熱交換器３は、接合部材３５をフィン３０にろう付けして接合することにより、接合部材３５とフィン３０の密着性を高めると共に、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０間の隙間を埋めることができる。よって、室外側熱交換器３は、図４に示すように、組立製造においてフィン３０にバラツキがあっても、剛性を高めることができ、外部要因などによるフィン３０の変形を抑制することができる。 As shown in FIG. 4, the joining member 35 is formed so as to extend along the parallel direction (horizontal direction Y) of the fins 30. The joining member 35 may be formed of one metal plate, or may be divided into a plurality of pieces and arranged along the parallel direction (horizontal direction Y) of the fins 30. Further, in the outdoor heat exchanger 3, the joining member 35 is brazed to the fin 30 to be joined to improve the adhesion between the joining member 35 and the fin 30, and the split heat exchangers 3A and 3B which are vertically adjacent to each other are improved. The gap between the fins 30 can be filled. Therefore, as shown in FIG. 4, the outdoor heat exchanger 3 can increase the rigidity even if the fins 30 have variations in the assembly manufacturing, and can suppress the deformation of the fins 30 due to an external factor or the like. ..
　ところで、室外側熱交換器３は、蒸発器として機能する場合に、冷媒の蒸発温度が周囲の空気温度に比べて低くなるため、空気中の水分がフィン３０の表面に結露する。室外側熱交換器３は、結露水Ｃが伝熱管３１又はフィン３０の間に滞留すると、該結露水Ｃが通風抵抗となり、熱交換効率が低下するおそれがある。また、室外側熱交換器３は、滞留した結露水Ｃが凍ると、通風抵抗となり、更に伝熱管３１を圧し潰して冷媒漏れを引き起こすおそれもある。そのため、室外側熱交換器３は、発生した結露水Ｃを下方へ誘導して速やかに排水させる必要がある。 By the way, when the outdoor heat exchanger 3 functions as an evaporator, the evaporation temperature of the refrigerant is lower than the ambient air temperature, so that the moisture in the air condenses on the surface of the fin 30. In the outdoor heat exchanger 3, if the dew condensation water C stays between the heat transfer tubes 31 or the fins 30, the dew condensation water C becomes a ventilation resistance, and the heat exchange efficiency may decrease. Further, in the outdoor heat exchanger 3, when the accumulated dew condensation water C freezes, it becomes a ventilation resistance, and further, the heat transfer tube 31 may be crushed to cause a refrigerant leak. Therefore, the outdoor heat exchanger 3 needs to guide the generated dew condensation water C downward and drain it promptly.
　そこで、実施の形態１に係る空気調和装置１００では、室外側熱交換器３が、間隔をあけて並列に配置された複数のフィン３０と、フィン３０を貫通して接続された複数の伝熱管３１と、有している。上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０が、接合部材３５によって連結されている。つまり、空気調和装置１００は、上部の分割熱交換器３Ａから流れ落ちる結露水Ｃが表面張力によって接合部材３５に誘引され、該結露水Ｃを下部の分割熱交換器３Ｂへと誘導することができるので、室外側熱交換器３のフィン３０及び伝熱管３１に結露水Ｃが滞留する事態を抑制できる。よって、空気調和装置１００は、結露水Ｃの排水性を促進できるので、熱交換効率を向上させることができ、結露水Ｃの凍結による伝熱管３１の破損なども抑制できる。 Therefore, in the air conditioner 100 according to the first embodiment, the outdoor heat exchanger 3 has a plurality of fins 30 arranged in parallel at intervals and a plurality of heat transfer tubes connected through the fins 30. It has 31 and. The fins 30 of the split heat exchangers 3A and 3B that are vertically adjacent to each other are connected by a joining member 35. That is, in the air conditioner 100, the dew condensation water C flowing down from the upper split heat exchanger 3A is attracted to the joining member 35 by the surface tension, and the dew condensation water C can be guided to the lower split heat exchanger 3B. Therefore, it is possible to suppress the situation where the dew condensation water C stays in the fin 30 and the heat transfer tube 31 of the outdoor heat exchanger 3. Therefore, since the air conditioner 100 can promote the drainage property of the dew condensation water C, the heat exchange efficiency can be improved, and damage to the heat transfer tube 31 due to freezing of the dew condensation water C can be suppressed.
　また、接合部材３５は、平板状に形成されており、通風方向Ｘにおけるフィン３０の一端側に配置され、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０の端部に当接して接合されている。よって、実施の形態１に係る空気調和装置１００は、簡易な構造で結露水Ｃの排水性を向上させることができるので、製造コストを抑制することができる。 Further, the joining member 35 is formed in a flat plate shape, is arranged on one end side of the fin 30 in the ventilation direction X, and abuts and joins the ends of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B. Has been done. Therefore, the air conditioner 100 according to the first embodiment can improve the drainage property of the condensed water C with a simple structure, so that the manufacturing cost can be suppressed.
　また、接合部材３５は、フィン３０にロウ付けされて接合されている。よって、室外側熱交換器３は、接合部材３５とフィン３０の密着性を高めると共に、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０間の隙間を埋めることができるので、組立製造においてフィン３０にバラツキがあっても剛性を高めることができ、外部要因などによるフィン３０の変形を抑制することができる。 Further, the joining member 35 is brazed to the fin 30 and joined. Therefore, the outdoor heat exchanger 3 can improve the adhesion between the joining member 35 and the fins 30 and fill the gap between the fins 30 of the vertically adjacent split heat exchangers 3A and 3B. Even if the fins 30 have variations, the rigidity can be increased, and deformation of the fins 30 due to external factors or the like can be suppressed.
　実施の形態２．
　次に、図５に基づいて、実施の形態２に係る空気調和装置を説明する。図５は、実施の形態２に係る空気調和装置の室外側熱交換器の要部を示した縦断面図である。なお、実施の形態１で空気調和装置１００と同一の構成については、同一の符号を付して、その説明を適宜省略する。 Embodiment 2.
Next, the air conditioner according to the second embodiment will be described with reference to FIG. FIG. 5 is a vertical cross-sectional view showing a main part of the outdoor heat exchanger of the air conditioner according to the second embodiment. The same configuration as that of the air conditioner 100 in the first embodiment is designated by the same reference numerals, and the description thereof will be omitted as appropriate.
　図５に示すように、実施の形態２に係る空気調和装置１００は、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０が、結露水Ｃの排水ガイドとして機能する接合部材３６によって連結されている。接合部材３６は、例えばアルミニウム合金等の金属板によって平板状に形成されており、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０の端面に挟まれてロウ付けにより接合されている。接合部材３６は、フィン３０の並列方向（左右方向Ｙ）に沿って延びるように形成されている。なお、接合部材３６は、一枚の金属板でもよいし、複数枚に分割され、フィン３０の並列方向（左右方向Ｙ）に沿って配置した構成でもよい。 As shown in FIG. 5, in the air conditioner 100 according to the second embodiment, the fins 30 of the vertically adjacent split heat exchangers 3A and 3B are connected by a joining member 36 that functions as a drainage guide for the condensed water C. ing. The joining member 36 is formed in a flat plate shape by, for example, a metal plate such as an aluminum alloy, and is sandwiched between the end faces of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B and joined by brazing. The joining member 36 is formed so as to extend along the parallel direction (horizontal direction Y) of the fins 30. The joining member 36 may be a single metal plate, or may be divided into a plurality of metal plates and arranged along the parallel direction (horizontal direction Y) of the fins 30.
　したがって、実施の形態２に係る空気調和装置１００は、上部の分割熱交換器３Ａから流れ落ちる結露水Ｃが表面張力によって接合部材３６に誘引され、該結露水Ｃを下部の分割熱交換器３Ｂへと誘導することができ、室外側熱交換器３のフィン３０及び伝熱管３１に結露水Ｃが滞留する事態を抑制できる。よって、空気調和装置１００は、結露水Ｃの排水性を促進できるので、熱交換効率を向上させることができ、結露水Ｃの凍結による伝熱管３１の破損なども抑制できる。 Therefore, in the air conditioner 100 according to the second embodiment, the dew condensation water C flowing down from the upper split heat exchanger 3A is attracted to the joining member 36 by surface tension, and the dew condensation water C is transferred to the lower split heat exchanger 3B. It is possible to suppress the situation where the condensed water C stays in the fin 30 and the heat transfer tube 31 of the outdoor heat exchanger 3. Therefore, since the air conditioner 100 can promote the drainage property of the dew condensation water C, the heat exchange efficiency can be improved, and damage to the heat transfer tube 31 due to freezing of the dew condensation water C can be suppressed.
　しかも、実施の形態２に係る空気調和装置１００は、接合部材３６が、平板状に形成されており、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０の端面に挟まれて接合された構成である。つまり、空気調和装置１００は、接合部材３６の表面を通風方向と略平行に配置しているので、通風抵抗を効果的に抑制することができ、熱交換効率を一層向上させることができる。よって、実施の形態２に係る空気調和装置１００は、簡易な構造で結露水Ｃの排水性を向上させることができるので、製造コストを抑制することができる。 Moreover, in the air conditioner 100 according to the second embodiment, the joining member 36 is formed in a flat plate shape, and is sandwiched between the end faces of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B. It is a composition. That is, since the air conditioner 100 is arranged substantially parallel to the ventilation direction on the surface of the joining member 36, the ventilation resistance can be effectively suppressed and the heat exchange efficiency can be further improved. Therefore, the air conditioner 100 according to the second embodiment can improve the drainage property of the condensed water C with a simple structure, so that the manufacturing cost can be suppressed.
　また、接合部材３６は、フィン３０にロウ付けされて接合されている。よって、室外側熱交換器３は、接合部材３６とフィン３０の密着性を高めると共に、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０間の隙間を埋めることができるので、組立製造においてフィン３０にバラツキがあっても剛性を高めることができ、外部要因などによるフィン３０の変形を抑制することができる。 Further, the joining member 36 is brazed to the fin 30 and joined. Therefore, the outdoor heat exchanger 3 can improve the adhesion between the joining member 36 and the fins 30 and fill the gap between the fins 30 of the split heat exchangers 3A and 3B that are adjacent to each other in the vertical direction. Even if the fins 30 have variations, the rigidity can be increased, and deformation of the fins 30 due to external factors or the like can be suppressed.

The joining member 37 is formed by bending a metal plate such as an aluminum alloy into an L shape so that the cross section in the vertical direction becomes an L shape. In the joining member 37, an L-shaped horizontal surface portion 37a is sandwiched between the end faces of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B, and is joined by brazing. Further, in the joining member 37, the L-shaped vertical surface portion 37b is arranged on the windward side of the fin 30 in the ventilation direction X, abuts on the end portion of the fin 30 of the lower split heat exchanger 3B, and is joined by brazing.

Further, the vertical surface portion 37b does not have to be strictly vertical, and may be substantially vertical.
　接合部材３７は、フィン３０の並列方向（左右方向Ｙ）に沿って延びるように形成されている。なお、接合部材３７は、単体で構成してもよいし、複数に分割され、フィン３０の並列方向（左右方向Ｙ）に沿って配置した構成でもよい。 The joining member 37 is formed so as to extend along the parallel direction (horizontal direction Y) of the fins 30. The joining member 37 may be configured as a single unit, or may be divided into a plurality of members and arranged along the parallel direction (horizontal direction Y) of the fins 30.
　また、接合部材３７は、Ｌ字の垂直面部３７ｂが、通風方向Ｘにおけるフィン３０の風下側に配置された構成でもよい。また、接合部材３７は、Ｌ字の垂直面部３７ｂが、上部における分割熱交換器３Ａのフィン３０の端部に当接して接合された構成でもよい。 Further, the joining member 37 may have a configuration in which the L-shaped vertical surface portion 37b is arranged on the leeward side of the fin 30 in the ventilation direction X. Further, the joining member 37 may have a configuration in which the L-shaped vertical surface portion 37b is brought into contact with the end portion of the fin 30 of the split heat exchanger 3A at the upper portion and joined.
　したがって、実施の形態３に係る空気調和装置１００は、上部の分割熱交換器３Ａから流れ落ちる結露水Ｃが表面張力によって接合部材３７に誘引され、該結露水Ｃを下部の分割熱交換器３Ｂへと誘導することができ、室外側熱交換器３のフィン３０及び伝熱管３１に結露水Ｃが滞留する事態を抑制できる。よって、空気調和装置１００は、結露水Ｃの排水性を促進できるので、熱交換効率を向上させることができ、結露水Ｃの凍結による伝熱管３１の破損なども抑制できる。 Therefore, in the air conditioner 100 according to the third embodiment, the dew condensation water C flowing down from the upper split heat exchanger 3A is attracted to the joining member 37 by surface tension, and the dew condensation water C is transferred to the lower split heat exchanger 3B. It is possible to suppress the situation where the condensed water C stays in the fin 30 and the heat transfer tube 31 of the outdoor heat exchanger 3. Therefore, since the air conditioner 100 can promote the drainage property of the dew condensation water C, the heat exchange efficiency can be improved, and damage to the heat transfer tube 31 due to freezing of the dew condensation water C can be suppressed.
　また、接合部材３７は、上下方向の断面がＬ字状に形成されている。そして、接合部材３７は、水平面部３７ａが、上下に隣り合う分割熱交換器３Ａ及び３Ｂのフィン３０の端面に挟まれて接合され、垂直面部３７ｂが、通風方向Ｘにおけるフィン３０の一端側に配置され、上下に隣り合う分割熱交換器３Ａ及び３Ｂのうち、一方の分割熱交換器３Ｂのフィン３０の端部に当接して接合されている。よって、実施の形態３に係る空気調和装置１００は、フィン３０に接合された水平面部３７ａと垂直面部３７ｂとによって、接合部材３７とフィン３０の密着性を高めることができるので、組立製造においてフィン３０にバラツキがあっても剛性を高めることができ、外部要因などによるフィン３０の変形を抑制することができる。 Further, the joint member 37 has an L-shaped cross section in the vertical direction. Then, in the joining member 37, the horizontal surface portion 37a is sandwiched between the end faces of the fins 30 of the vertically adjacent split heat exchangers 3A and 3B and joined, and the vertical surface portion 37b is on one end side of the fin 30 in the ventilation direction X.
