しかしながら、従来の構成による熱交換器をエアコンの本体に収納した場合、ファンの前面、上面、背面を囲む構造となり、ファンの前面下部を囲む配置には成り得ない。すなわち、限られたエアコンの本体サイズの中で熱交換器を最大限に収納するには不適当な形態である。また、ファンの軸心を通る水平断面において熱交換器と交差する面が垂直に成り得ないことがあり、効果的な本体の薄型化とは成らない。   However, when a heat exchanger having a conventional configuration is housed in the main body of an air conditioner, it has a structure that surrounds the front, top, and back of the fan, and cannot be arranged to surround the lower front of the fan. That is, it is an unsuitable form for accommodating the heat exchanger to the maximum extent within the limited body size of the air conditioner. In addition, in a horizontal section passing through the axis of the fan, the surface intersecting with the heat exchanger may not be vertical, and the main body cannot be effectively thinned.

本発明は上記従来の問題点を解決するものを提供することを目的とする。   An object of the present invention is to provide a solution to the above-mentioned conventional problems.

In the heat exchanger with fins mounted on the indoor unit of the air conditioner that constitutes the wind circuit from the once-through fan, the heat exchanger with fins is in the middle of the wind circuit from the inlet port to the once-through fan or from the once-through fan to the outlet port The front-side heat exchanger and the back-side heat exchanger are arranged in the middle of the wind circuit, and the front-side heat exchanger and the back-side heat exchanger are arranged at predetermined intervals, respectively. It is composed of a large number of fins through which gas flows and a large number of heat transfer tubes that are inserted substantially perpendicular to the fins and through which the fluid flows, and the windward leading edge and leeward trailing edge of the fins of the front side heat exchanger Is that However, two portions formed so as to be composed of two straight portions having the same obtuse angle and one curved portion connecting the two straight lines are provided in one direction so as to draw a general arc. With the fins, the width and length of the front heat exchanger (the distance between the windward leading edge and the windward trailing edge) of the fins differing by two or more. It is a heat exchanger.

本発明のフィン付き熱交換器は、１本の曲線部を挟む前面熱交換器の幅長さ（前記フィ
ンの風上前縁と風下後縁の距離）が異なり、２箇所以上で折り曲がりことを特徴とするフィン付き熱交換器であり、熱交換器の幅長さの小さいものを、ファンの直下流に配置することにより、本体厚さを小さくすることができる。また、風速の速い領域に熱交換器の幅長さの大きいものを配置して、逆に風速の遅い領域に熱交換器の幅長さの小さいものを配置することにより、熱交換器能力の向上を図ることができる。 The heat exchanger with fins of the present invention is different in the width and length (distance between the windward leading edge and leeward trailing edge of the fin) of the front heat exchanger sandwiching one curved portion, and bends at two or more places. The heat exchanger with fins is characterized in that the thickness of the main body can be reduced by disposing a heat exchanger having a small width and length immediately downstream of the fan.

ここで、本実施の形態１では、各熱交換器の厚さＡ、Ｂ、Ｃの長さが少なくとも１つは異なるものである。   Here, in the first embodiment, at least one of the lengths of the thicknesses A, B, and C of each heat exchanger is different.

これは、この１本の曲線部を挟む前記前面熱交換器の幅長さ（前記フィンの風上前縁と
風下後縁の距離）すなわち厚さＡとＢあるいはＢとＣが異なることを特徴とするフィン付き熱交換器である。熱交換器の幅長さの小さいものを、ファン５の水平直径方向の直下流に配置することにより、本体厚さを小さくすることができる。また、熱交換器能力を向上させる観点から、風速の速い領域に熱交換器の幅長さの大きいものを配置するのが有効である。 This is characterized in that the width of the front heat exchanger (the distance between the windward leading edge and the leeward trailing edge) of the fins, that is, the thicknesses A and B or B and C, sandwiching this one curved portion. It is a heat exchanger with a fin. By disposing a heat exchanger having a small width length immediately downstream of the fan 5 in the horizontal diameter direction, the thickness of the main body can be reduced. Further, from the viewpoint of improving the heat exchanger capacity, it is effective to arrange a heat exchanger having a large width in a region where the wind speed is high.

以上のように、本第１の実施の形態は、１本の曲線部を挟む前面熱交換器の幅長さ（前記フィンの風上前縁と風下後縁の距離）が異なり、２箇所以上で折り曲がることを特徴とするフィン付き熱交換器であり、熱交換器の幅長さの小さいものを、ファンの直下流に配置することにより、本体厚さを小さくすることができる。また、風速の速い領域に熱交換器の幅長さの大きいものを配置して、逆に風速の遅い領域に熱交換器の幅長さの小さいものを配置することにより、熱交換器能力の向上を図ることができる。   As described above, in the first embodiment, the width and length of the front heat exchanger (distance between the windward leading edge and the leeward trailing edge of the fin) sandwiching one curved portion is different, and two or more locations are provided. The heat exchanger with fins is characterized in that the thickness of the main body can be reduced by disposing a heat exchanger having a small width and length immediately downstream of the fan.

As shown in FIG. 4, this is arranged in the lower part of the air conditioner body from the smallest thickness. As a result, the thickness gradually increases from the lower part to the upper part of the air conditioner body, and the design can be improved. In addition, due to the arrangement of functional parts and the like, in general, an indoor unit of an air conditioner has a large suction resistance from the lower part of the main body, and thus the ventilation resistance gradually increases from the upper part toward the lower part. Therefore, it is effective to sequentially arrange the heat exchangers having a large thickness in the region where the wind speed is high.

以上のように、本第２の実施の形態は、各熱交換器の厚さが順に小さくなる形状にして、空気調和機本体の下部に厚さの小さいものから配置することによって、空気調和機本体の下部から上部に向かって徐々に厚みが増し、意匠的に優れた形態に成り得る。また一般に、機能部品の配置などにより、一般にエアコンの室内機は、本体の下部からの吸込み抵抗が大きいため、上部から下部に向かって徐々に通風抵抗が増加する。従って、風速の速い領域に熱交換器の厚さ長さの大きいものを順番に配置することが熱交換器能力の向上に繋がる。   As described above, in the second embodiment, the thickness of each heat exchanger is reduced in order, and the air conditioner is arranged in the lower part of the air conditioner body from the smallest thickness. The thickness gradually increases from the lower part to the upper part of the main body, and the form can be excellent in design. In general, due to the arrangement of functional parts and the like, in general, an air conditioner indoor unit has a large suction resistance from the lower part of the main body, and therefore the ventilation resistance gradually increases from the upper part toward the lower part. Therefore, arranging heat exchangers with a large thickness in order in a region where the wind speed is high leads to an improvement in heat exchanger capacity.

As shown in FIG. 5, the number of heat transfer tubes inserted in the thickness direction (number of rows) is reduced corresponding to the thickness. That is, as shown in FIG. 5, the number (number of columns) is set to 3, 2, and 1 in the order of thicknesses A, B, and C. As a result, it is possible to improve the heat transfer performance and the productivity of the heat exchanger.

（実施の形態７）
図２は、本発明の実施の形態７のフィン付き熱交換器のフィン平面図である。 (Embodiment 7)
FIG. 2 is a fin plan view of the heat exchanger with fins according to the seventh embodiment of the present invention.

本第７の実施の形態は、図２に示すように図１のフィンを連続プレス加工してできる３枚のフィンをプレスの送り方向に連続して並べたイメージ図で説明できる。ここで、２―Ｏ―１と２―Ｉ―１の平均距離をＡ、２―Ｏ―２と２−Ｉ―２の平均距離をＢ、２―Ｏ―３と２−Ｉ―３の平均距離をＣとして、折曲がった１番目の熱交換器の上下の角度をＴとして、折曲がった２番目の熱交換器の上下の角度をＳとして、プレス加工する時の送り方向と折曲がった熱交換器の上下の厚さ方向の角度α、β、γとして、プレス加工する時の送り幅をＸとすると以下の関係式が成り立つ。   As shown in FIG. 2, the seventh embodiment can be explained by an image diagram in which three fins formed by continuously pressing the fins of FIG. 1 are continuously arranged in the feed direction of the press. Here, the average distance between 2-O-1 and 2-I-1 is A, the average distance between 2-O-2 and 2-I-2 is B, the average distance between 2-O-3 and 2-I-3 The distance is C, the up and down angle of the bent first heat exchanger is T, and the up and down angle of the bent second heat exchanger is S, and the feed direction when pressing is bent. Assuming that the feed width at the time of pressing is X as the angles α, β, γ in the upper and lower thickness directions of the heat exchanger, the following relational expression is established.

ＣＯＳ α ＝Ａ ／ Ｘ
ＣＯＳ β ＝ Ｂ ／ Ｘ
ＣＯＳ γ ＝ Ｃ ／ Ｘ
β ＝ α ＋ Ｔ
γ ＝ β ＋ Ｓ
ここで、Ａ、Ｂ、Ｃ、Ｔ、Ｓの値は既知であり、未知数は、α、β、γ、Ｘであるので、５種の関係式から一意に決定することができる。これにり、送り方向幅を同一になるように熱交換器を製造することによって、廃材の発生を極めて減少させることになる。 COS α = A / X
COS β = B / X
COS γ = C / X
β = α + T
γ = β + S
Here, since the values of A, B, C, T, and S are known and the unknowns are α, β, γ, and X, they can be uniquely determined from five types of relational expressions. Accordingly, the production of waste materials is greatly reduced by manufacturing the heat exchanger so that the widths in the feed direction are the same.

以上のように、第７の実施の形態は、フィン付き熱交換器の前記フィンを連続プレス加工する際、送り方向に対して熱交換器を傾斜させて、曲線部を挟む幅長さ（前記フィンの
風上前縁と風下後縁の距離）が異なる前面側熱交換器が、送り方向幅を同一になるように熱交換器を製造することにより、１枚のフィンとして連続プレス加工するので、あまりフィン材の廃材を出さず、効率的に安価に製造することができる。 As described above, according to the seventh embodiment, when the fins of the finned heat exchanger are continuously pressed, the heat exchanger is inclined with respect to the feeding direction, and the width (the above-described length) sandwiches the curved portion.
