以下、本発明の空気調和機を図面に基づいて説明する。図１は空気調和機の室内機、室外機、及び、リモコンの図である。空気調和機は、室内に配置され冷暖房を行う室内機と、ユーザが室内機の運転を行うために操作するリモコンと、室外に配置され室内機から循環された冷媒が外気と熱交換を行う室外機とを備える。空気調和機を構成する室内機と室外機とは、通常、内部に冷媒が流れる冷媒配管（図示せず）によって接続される。 Hereinafter, an air conditioner of the present invention will be described with reference to the drawings. FIG. 1 is a diagram of an indoor unit, an outdoor unit, and a remote controller of an air conditioner. The air conditioner is an indoor unit that is placed indoors for air conditioning and heating, a remote controller that is operated by a user to operate the indoor unit, and an outdoor unit that is placed outdoors and in which the refrigerant circulated from the indoor unit exchanges heat with the outside air Equipped with a machine. The indoor unit and the outdoor unit constituting the air conditioner are usually connected by a refrigerant pipe (not shown) through which a refrigerant flows.
図２は、室外機の外郭を構成する外板の一部 （図１参照）を外した状態を示す図である。図２に示すように、室外機は、仕切り板と電装品箱とリード線支持部品とにより、熱交換器室と機械室とを区分（分割）している。熱交換器室には、冷媒配管を循環する冷媒の外気との熱交換を促進するプロペラファンとその駆動用のモータ、プロペラファンを回転自在に支持するプロペラファン支柱（送風機）、および外気と循環する冷媒を熱交換する熱交換器が配設される。機械室には、循環する冷媒を高温高圧のガス冷媒にする圧縮機、常温・高圧の液状冷媒を低温・低圧の液状冷媒にする電動膨張弁（図示せず）、電気部品のリアクタ（図示せず）、および、冷媒が流れる冷媒配管の伝熱管（図示せず）が配設される。電装品箱には、室外機を制御する電装品が収納され、電装品の上部には電装品蓋が被せられる。 FIG. 2 is a view showing a state in which a part of the outer plate (see FIG. 1) constituting the outer shell of the outdoor unit is removed. As shown in FIG. 2, the outdoor unit divides (divides) the heat exchanger room and the machine room by a partition plate, an electrical component box, and a lead wire support part. In the heat exchanger chamber, a propeller fan that promotes heat exchange with the outside air of the refrigerant circulating in the refrigerant pipe, a motor for driving the propeller fan, a propeller fan support (blower) that rotatably supports the propeller fan, and circulation with the outside air A heat exchanger for exchanging heat with the refrigerant is disposed. The machine room has a compressor that converts the circulating refrigerant into a high-temperature and high-pressure gas refrigerant, an electric expansion valve (not shown) that converts liquid refrigerant at room temperature and high pressure into liquid refrigerant at low temperature and low pressure, and a reactor for electrical components (not shown). And a heat transfer pipe (not shown) of the refrigerant pipe through which the refrigerant flows. The electrical component box stores electrical components that control the outdoor unit, and an electrical component lid is placed on the electrical component.
第１熱交換器は、丸孔を持つ多数の短冊状のフィンを横方向に重ね合わせ丸孔に銅パイプを通して構成される。第２熱交換器も同様に、丸孔を持つ多数の短冊状のフィンを横方向に重ねて丸孔にパイプを通して構成される。第１熱交換器と第２熱交換器の機械室側端部にはエンドプレートが設置される。また、第１熱交換器の熱交換器室側端部にはエンドプレートが設置される。 The first heat exchanger is configured by laminating a large number of strip-shaped fins having round holes in the lateral direction and passing the copper pipe through the round holes. Similarly, the second heat exchanger is configured by passing a plurality of strip-shaped fins having round holes in the horizontal direction and passing the pipes through the round holes. End plates are installed at the machine room side ends of the first heat exchanger and the second heat exchanger. An end plate is installed at the end of the first heat exchanger on the heat exchanger chamber side.
複数の熱交換器を重ね合わせるとともに複数の熱交換器を端部で連結し一体化した空気調和機の室外機の熱交換器の製造方法として、以下二つの方法がある。つまり、複数の熱交換器の端部を一枚のエンドプレートで連結する方法と、複数の熱交換器のそれぞれの端部にエンドプレートを設置し、熱交換器を重ね合わせる際にエンドプレートのツメ部を引っかけ熱交換器を連結する方法である。 There are the following two methods for manufacturing a heat exchanger for an outdoor unit of an air conditioner in which a plurality of heat exchangers are overlapped and a plurality of heat exchangers are connected and integrated at the ends. In other words, a method of connecting the end portions of a plurality of heat exchangers with one end plate, and an end plate installed at each end portion of the plurality of heat exchangers, and when the heat exchangers are overlapped, This is a method of hooking a claw portion and connecting a heat exchanger.
複数の熱交換器の端部を一枚のエンドプレートで連結する場合、空気調和機の室外機の熱交換器は下記の手順で製造される。つまり、（１）：コイル材からフィンを生産する、（２）：フィンを複数枚重ねる、（３）：Ｕ字に曲げたパイプを（２）に挿入する、（４）：（３）を複数枚重ねる、（５）：（４）の機械室側のエンドプレートを設置する、（６）：（５）のパイプを拡管し、パイプをフィンおよびエンドプレートと圧着させる。 When the end portions of a plurality of heat exchangers are connected by one end plate, the heat exchanger of the outdoor unit of the air conditioner is manufactured by the following procedure. That is, (1): producing fins from coil material, (2): stacking a plurality of fins, (3): inserting a U-shaped pipe into (2), (4): (3) A plurality of sheets are stacked, (5): install the end plate on the machine room side of (4), (6): expand the pipe of (5), and crimp the pipe to the fin and end plate.
一方、複数の熱交換器をそれぞれに設置されるエンドプレートに設けられたツメで引っかけて連結する場合、空気調和機の室外機の熱交換器は下記の手順で製造される。つまり、（１）：コイル材からフィンを生産する、（２）：フィンを複数枚重ねる、（３）：Ｕ字に曲げたパイプを（２）に挿入する、（４）：（３）の機械室側のエンドプレートを設置する、（５）：（４）のパイプを拡管し、パイプをフィンおよびエンドプレートと圧着させる、（６）：（５）を複数枚重ね、それぞれに設けられたエンドプレートのツメを引っかける。 On the other hand, when connecting a plurality of heat exchangers with hooks provided on end plates installed in the heat exchangers, the heat exchanger of the outdoor unit of the air conditioner is manufactured by the following procedure. That is, (1): producing fins from coil material, (2): stacking a plurality of fins, (3): inserting a U-shaped pipe into (2), (4): (3) Install the end plate on the machine room side, expand the pipe of (5) :( 4), and press-fit the pipe with the fin and end plate. (6): Overlay multiple pieces of (5). Hook the end plate tab.
単一の仕様（パイプの径やパイプのピッチなど）の熱交換器を継続して製造する場合、複数の熱交換器の端部を一枚のエンドプレートで連結する方法を用いると、エンドプレートの引っかけ部を狙って組み付けるという手間を省くことができる。すなわち、複数の熱交換器のうち一方がφ７のパイプ×1.3mmのフィンピッチ×1000mmの長さで、他方がφ７×1.2mmのフィンピッチ×900mmの長さであり、これを継続して製造する場合、熱交換器の製造設備はこれを一体で製造することで、一種類の製造設備で製造することができる。 When continuously manufacturing heat exchangers with a single specification (pipe diameter, pipe pitch, etc.), the end plate can be obtained by connecting the ends of multiple heat exchangers with a single end plate. It is possible to save the labor of assembling with the aim of the hook part. That is, one of the heat exchangers is φ7 pipe × 1.3 mm fin pitch × 1000 mm length, and the other is φ7 × 1.2 mm fin pitch × 900 mm length. When doing, the manufacturing equipment of a heat exchanger can be manufactured by one type of manufacturing equipment by manufacturing this integrally.
その一方で、頻繁に仕様の異なる熱交換器を製造する場合、熱交換器毎にエンドプレートを設置する方法を用いると、熱交換器の仕様変更への対応が容易となる。すなわち、複数の熱交換器のうち一方がφ７のパイプ×1.3mmのフィンピッチ×1000mmの長さで、他方がφ７×1.2mmのフィンピッチ×900mmの長さであり、また別の仕様の熱交換器のうち一方がφ７のパイプ×1.3mmのフィンピッチ×1000mmの長さで、他方がφ8のパイプ×1.2mmのフィンピッチ×900mmである場合、φ７用の製造設備とφ８用の製造設備があれば、φ７とφ８を組み合わせた様々な仕様の熱交換器を製造することが可能となる。 On the other hand, when manufacturing heat exchangers with different specifications frequently, using a method of installing an end plate for each heat exchanger makes it easy to cope with changes in the specifications of the heat exchanger. That is, one of a plurality of heat exchangers has a φ7 pipe × 1.3 mm fin pitch × 1000 mm length, and the other has a φ7 × 1.2 mm fin pitch × 900 mm length. When one of the exchangers is φ7 pipe x 1.3mm fin pitch x 1000mm length and the other is φ8 pipe x 1.2mm fin pitch x 900mm, φ7 production equipment and φ8 production equipment If there is, it becomes possible to manufacture the heat exchanger of various specifications which combined (phi) 7 and (phi) 8.
熱交換器毎に設置されるエンドプレートは略Ｌ字形状で、フィンに接する（フィンと対向する）床部と、フィンから立ち上がる方向（床部と垂直方向）に設けられる壁部とにより構成される。床部にはパイプを通す穴列が設けられ、壁部には第１熱交換器と第２熱交換器とを引っかけるツメ部（第１熱交換器における凸部及び開口部と、第２熱交換器におけるツメ部）が設けられる。床部と壁部の端部は、ツメ部の形成で曲がる部分はあるがその高さは略一定であり且つ略連続している。 The end plate installed for each heat exchanger is substantially L-shaped, and is composed of a floor portion in contact with the fin (opposite the fin) and a wall portion provided in a direction rising from the fin (perpendicular to the floor portion). The The floor portion is provided with a row of holes through which the pipe passes, and the wall portion is a claw portion that hooks the first heat exchanger and the second heat exchanger (the convex portion and the opening portion in the first heat exchanger, and the second heat exchanger A claw portion in the exchanger is provided. The ends of the floor portion and the wall portion are bent by the formation of the claw portion, but the height is substantially constant and substantially continuous.
エンドプレートの床部のパイプを通る穴列の穴のうち、複数の穴はバーリング穴とし、残りの穴はパイプ径に対して所定の隙間を持つ程度に大きな穴とする。これにより、すべての穴がバーリング穴である場合と比較し、拡管の際の拡管器の挿入抵抗を小さくすることができ、設備に必要とされる能力を低減することができる。 Among the holes in the hole row passing through the pipe of the floor portion of the end plate, a plurality of holes are burring holes, and the remaining holes are large enough to have a predetermined gap with respect to the pipe diameter. Thereby, compared with the case where all the holes are burring holes, the insertion resistance of the tube expander at the time of tube expansion can be reduced, and the capacity required for the facility can be reduced.
エンドプレートの壁部の端部は、ツメ部を設けることにより曲がる部分はあるが、高さは一定であり且つ連続している。 The end portion of the wall portion of the end plate is bent by providing the claw portion, but the height is constant and continuous.
壁の高さが不均一であり、局所的に壁が高くなっている場合、壁の高い部分は局所的に床部を曲げ軸とする曲げの力に対して強度が向上するが、壁の高い部分と低い部分との境界部分に応力が集中し、壁部の座屈の原因となる。一方、壁の高さが一定である場合、同様の力に対する応力集中が生じにくく、強度の向上につながる。 When the height of the wall is uneven and the wall is locally high, the high part of the wall improves the strength against the bending force with the floor as the bending axis, Stress concentrates at the boundary between the high part and the low part, causing the wall to buckle. On the other hand, when the height of the wall is constant, stress concentration with respect to the same force is unlikely to occur, leading to an improvement in strength.
壁部の端部は略連続しており、ツメ部（第１熱交換器における凸部及び開口部）の周囲でも完全には切り欠かれてはいない。床部を曲げ軸とする力により壁部にはその高さに応じた応力が発生する。その応力の大きさは、下記の式で表される断面二次モーメントにより概算することができる。 The end portion of the wall portion is substantially continuous, and is not completely cut out even around the claw portion (the convex portion and the opening portion in the first heat exchanger). A stress corresponding to the height of the wall is generated by the force having the floor as a bending axis. The magnitude of the stress can be estimated from the cross-sectional second moment represented by the following formula.
また、
Also,
上式により、壁の高さが高いほど断面二次モーメントは大きく、その逆に壁が切り欠かれている場合断面二次モーメントは小さく、切り欠かれる程度が大きいほど壁部に生じる応力は大きくなり、連続した壁の一部に切欠きがある場合その切り欠き部に応力が集中し、エンドプレートが曲がるなどの変形につながる。すなわち、切り欠き部はその切り欠きが大きいほど、切り欠き部での変形は大きくなり、その一方で、切り欠き部を持たない場合、局所的に応力が大きくなることを防ぐことができる。すなわち、このような形状とすることで、エンドプレートは高強度化され、同一形状の熱交換器とする場合にはエンドプレートの薄肉化による省資源化、低材料コスト化を図ることができる。また、このような形状とすることで、エンドプレートは高強度化され、同一形状の熱交換器とする場合には、輸送や据え付けなど室外機に外力が加わる場合における室外機の信頼性を向上させられる。
From the above equation, the higher the height of the wall, the larger the moment of inertia of the cross section, and conversely, if the wall is notched, the moment of inertia of the cross section is small, and the greater the degree of notch, the greater the stress generated on the wall. Therefore, when there is a notch in a part of the continuous wall, stress concentrates on the notch, leading to deformation such as bending of the end plate. That is, the larger the notch, the greater the deformation at the notch. On the other hand, when there is no notch, it is possible to prevent the stress from locally increasing. That is, by adopting such a shape, the strength of the end plate is increased, and in the case of a heat exchanger having the same shape, it is possible to save resources and reduce material costs by reducing the thickness of the end plate. In addition, by adopting such a shape, the strength of the end plate is increased, and when the heat exchanger has the same shape, the reliability of the outdoor unit is improved when an external force is applied to the outdoor unit, such as transportation and installation. Be made.
エンドプレートの壁部には複数のツメ部が設けられ、複数枚重ねる熱交換器の隣り合う熱交換器同士を引っかける形状をしている。一対のツメ（第１熱交換器における凸部及び開口部と、第２熱交換器におけるツメ部）において、一方の熱交換器のエンドプレートにはオスの引っかけ部があり、他方の熱交換器のエンドプレートにはメスの引っかけ部がある。 A plurality of claw portions are provided on the wall portion of the end plate, and the heat exchangers adjacent to each other are stacked so as to hook each other. In a pair of claws (projections and openings in the first heat exchanger and claws in the second heat exchanger), one end plate of the heat exchanger has a male hook, and the other heat exchanger The end plate has a hook for a knife.
オスのツメ部（第２熱交換器におけるツメ部）は、床部に垂直方向であって、壁部と平行する方向に、壁部の反対側の床部の端部に設けられる。オスのツメ部は床部の幅の範囲内で設けられ、その左右の床部にはツメ部成型用の小さな切り欠きが設けられる。 The male claw portion (claw portion in the second heat exchanger) is provided at an end portion of the floor portion opposite to the wall portion in a direction perpendicular to the floor portion and parallel to the wall portion. The male claw portion is provided within the range of the width of the floor portion, and the left and right floor portions are provided with small notches for claw portion molding.
一方、メスのツメ部（第１熱交換器における凸部及び開口部）は、床部に鉛直に、壁部の一部として、壁部の一部を外側（第２熱交換器側）へ曲げて設けられる。また、この曲げられた部分の床部側には開口が設けられ、この開口にオスのツメ部が挿入され、オスのツメ部とメスのツメ部が引っ掛かることにより、隣り合う熱交換器が一体化される。 On the other hand, the female claw part (the convex part and the opening part in the first heat exchanger) is perpendicular to the floor part, and part of the wall part is directed to the outside (second heat exchanger side) as a part of the wall part. Bent and provided. In addition, an opening is provided on the floor portion side of the bent portion, and a male claw portion is inserted into the opening, and the male claw portion and the female claw portion are hooked, so that adjacent heat exchangers are integrated. It becomes.
さらに、複数の熱交換器を、それぞれに設置されるエンドプレートに設けられたツメで引っかけて連結する場合、同じ仕様の熱交換器を複数枚同時に拡管する。この場合、隣り合う熱交換器のパイプおよびエンドプレートにツメ部が干渉しないようなツメ部の形状とする。また、拡管設備とツメ部とが干渉しないようなエンドプレートのツメ部の形状とする。 Furthermore, when a plurality of heat exchangers are connected by hooks provided on end plates installed in the heat exchangers, a plurality of heat exchangers having the same specification are expanded simultaneously. In this case, it is set as the shape of a nail | claw part so that a nail | claw part does not interfere with the pipe and end plate of an adjacent heat exchanger. Moreover, it is set as the shape of the nail | claw part of an end plate so that a pipe expansion equipment and a nail | claw part may not interfere.
このような形状のツメ部とすることで、ツメ部のためだけに必要となる材料を低減することができ、省資源化、低材料コスト化を進めることができる。 By setting it as a nail | claw part of such a shape, the material required only for a nail | claw part can be reduced, and resource saving and cost reduction of a material can be advanced.
また、類似の形状として、以下の形状でも同様の効果を得ることができる。すなわち、オスのツメ部が床部の幅より出っ張ってもうけられ、一方メスのツメ部は壁部の床部側にオスのツメ部を引っかける開口を設ける形状とする。オスのツメ部は飛び出すことによる強度低下の可能性はあるが、メスのツメ部は曲げ部な無くなることにより高強度化される。 Similar effects can be obtained with the following shapes as similar shapes. That is, even if the male claw portion protrudes from the width of the floor portion, the female claw portion has a shape in which an opening for hooking the male claw portion is provided on the floor side of the wall portion. Although there is a possibility that the strength of the male claw portion may drop due to jumping out, the strength of the female claw portion is increased by the absence of the bent portion.
以上説明したようなエンドプレートを用いることで、エンドプレートが高強度化され、外力に対する信頼性の向上、薄肉化することによる省資源化および低材料コスト化を図ることが可能となる。 By using the end plate as described above, it is possible to increase the strength of the end plate, improve the reliability against external force, save resources by reducing the thickness, and reduce the material cost.
