When the heat exchanger is composed of a plurality of rows, the length of the outer row and the inner row of the heat exchanger is different. Therefore, the end plate on the closed side of the U-shaped copper tube is installed separately in the outer row and the inner row. Resin the U-shaped copper tube in the outer row and the U-shaped copper tube in the inner row after the end plate is installed only in the outer row and bent into the L or U shape after being bent into the U shape In some cases, the band was bound together.

しかしながら、前記従来の構成では、熱交換器を固定するための端板を熱交換器製造時に組み込んでおく必要があり、組立や市場での補修時のネジ締め等によりこの端板部を破損した場合には熱交換器全体を交換しなければならずコストアップの要因になるという課題を有していた。   However, in the conventional configuration, it is necessary to incorporate an end plate for fixing the heat exchanger at the time of manufacturing the heat exchanger, and the end plate portion is damaged by assembly or tightening screws at the time of repair in the market. In some cases, the entire heat exchanger must be replaced, which has the problem of increasing costs.

さらに熱交換器が複数列により構成される場合、それぞれの列を結合する部品が必要であり、また取り付け工数を要する等の課題を有していた。   Furthermore, when a heat exchanger is comprised by multiple rows | lines, the components which couple | bond each row | line were required and had the subject of requiring an installation man-hour.

本発明は、前記従来の課題を解決するもので、簡単な構造で端板だけを交換可能としてロスコストを削減し、さらに部品点数を削減して、より安価で組み立てやすい分離型空気調和機の室外ユニットを提供することを目的とする。   The present invention solves the above-mentioned conventional problems, and it is possible to replace only the end plate with a simple structure, thereby reducing the loss cost, further reducing the number of parts, and making the outdoor unit of the separate type air conditioner more inexpensive and easy to assemble.

図１は、本発明の第１の実施の形態における分離型空気調和機の室外ユニットの一部を省略した斜視図、図２は、正面図、図３は、平断面図を示すものである。図１および図２、図３において、従来の技術の図８および図９と同じ構成要素については同じ符号を用い、説明を省略する。 (Embodiment 1)
FIG. 1 is a perspective view in which a part of an outdoor unit of a separation-type air conditioner according to the first embodiment of the present invention is omitted, FIG. 2 is a front view, and FIG. 3 is a plan sectional view. . 1, 2, and 3, the same components as those in FIGS. 8 and 9 of the prior art are denoted by the same reference numerals, and description thereof is omitted.

図１および図２、図３において、熱交換器１０はＵ字形銅管１０ａ、１０ｂ、フィン１０ｃ、１０ｄにより構成される。熱交換器１０のＵ字形銅管の閉じた側には、端板１２がＵ字形銅管１０ａ、１０ｂ、フィン１０ｃ、１０ｄに接して取り付けられている。この端板１２はフィン１０ｃ、１０ｄの端面に沿った平面部１２ａと、平面部１２ａをＵ字形銅管１０ａ、１０ｂが貫通する開口部１２ｂと、開口部１２ｂの最外形周りを略矩形に取り囲み、Ｕ字形銅管１０ａ、１０ｂに沿った立面部１２ｃを有している。さらに立面部１２ｃと対向して、Ｕ字形銅管を挟持固定するために弾性を有するアーム１２ｄを設け、立面
部１２ｃ及びアーム１２ｄの対向面上でかつＵ字形銅管の内側面と平面部１２ａとの間に、それぞれ固定用ツメ１２ｅが設けられている。 1, 2, and 3, the heat exchanger 10 includes U-shaped copper tubes 10 a and 10 b and fins 10 c and 10 d. On the closed side of the U-shaped copper tube of the heat exchanger 10, an end plate 12 is attached in contact with the U-shaped copper tubes 10a and 10b and the fins 10c and 10d. The end plate 12 surrounds the flat portion 12a along the end surfaces of the fins 10c and 10d, the opening 12b through which the U-shaped copper tubes 10a and 10b penetrate the flat portion 12a, and the outer periphery of the opening 12b in a substantially rectangular shape. , And U-shaped copper pipes 10a and 10b. Further, an arm 12d having elasticity is provided so as to face and fix the U-shaped copper tube so as to be opposed to the raised surface portion 12c, and on the opposed surfaces of the raised surface portion 12c and the arm 12d and on the inner surface and the plane of the U-shaped copper tube. A fixing claw 12e is provided between each portion 12a.

以上のように構成された分離型空気調和機の室外ユニットについて、以下その動作、作用を説明する。   The operation and action of the outdoor unit of the separation type air conditioner configured as described above will be described below.

まず、熱交換器製造時には、熱交換器１０のＵ字形銅管１０ａ、１０ｂの閉じた側に端板を設けず、熱交換器完成後に端板１２を熱交換器１０側方向に挿入することで、アーム１２ｄの弾性により固定用ツメ１２ｅを拡げて熱交換器１０のＵ字型銅管１０ａ、１０ｂの閉じた部分に取り付けることができる。   First, when manufacturing the heat exchanger, the end plate is not provided on the closed side of the U-shaped copper tubes 10a, 10b of the heat exchanger 10, and the end plate 12 is inserted in the direction of the heat exchanger 10 after the heat exchanger is completed. Thus, the fixing claw 12e can be expanded by the elasticity of the arm 12d and attached to the closed portions of the U-shaped copper tubes 10a, 10b of the heat exchanger 10.

また、熱交換器１０は輸送や空調時の振動等により上下、左右および前後方向に力が加わり移動することが考えられるが、樹脂製端板１２を挿入設置することにより上下、左右および前方向に対して保持する事ができ、さらに固定用ツメ１２ｅにより後方向に対して保持することができる。   Further, the heat exchanger 10 may be moved by applying force in the vertical and horizontal and front and rear directions due to vibrations during transportation and air conditioning, but by inserting and installing the resin end plate 12, the vertical and horizontal and front and rear directions may be considered. And can be held in the rearward direction by the fixing claw 12e.

また、市場等において端板１２を破損した場合には、熱交換器１０側と逆方向に引き抜くことで、アーム１２ｄの弾性により固定用ツメ１２ｅを拡げて熱交換器１０から端板１２のみを簡単に取り外すことができ、容易に交換することができる。   Further, when the end plate 12 is damaged in the market or the like, the fixing claw 12e is expanded by the elasticity of the arm 12d by pulling it out in the direction opposite to the heat exchanger 10 side, and only the end plate 12 is removed from the heat exchanger 10. It can be easily removed and easily replaced.

更に本実施の形態では、端板１２の固定強度を上げるために、外箱底板２および外箱左側板３にネジ１１で固定されている。   Further, in the present embodiment, in order to increase the fixing strength of the end plate 12, the end plate 12 is fixed to the outer box bottom plate 2 and the outer box left side plate 3 with screws 11.

また、端板１２は弾性を要求される為、本実施の形態では従来の端板で使用されていた金属製ではなく、樹脂製端板を使用する。更に、アームの根元に所定の切欠きを設けることによって弾性が向上する。   In addition, since the end plate 12 is required to be elastic, in this embodiment, a resin end plate is used instead of the metal used in the conventional end plate. Furthermore, the elasticity is improved by providing a predetermined notch at the base of the arm.

一方、熱交換器がＬ型の複数列で構成される場合、従来の構成では例えば外側列と内側列にそれぞれ金属製端板を設けＬ曲げ加工の後にネジ固定する等、それぞれの列を結合するための部品が必要であったが、この構成によれば熱交換器１０をＬ曲げ加工した後に端板１２を挿入固定できるので１部品により熱交換器１０を保持することが可能となる。   On the other hand, when the heat exchanger is composed of multiple L-shaped rows, in the conventional configuration, for example, metal end plates are provided in the outer row and the inner row, and the screws are fixed after L bending, for example. However, according to this configuration, the end plate 12 can be inserted and fixed after the heat exchanger 10 is bent to L, so that the heat exchanger 10 can be held by one component.

以上のように、本実施の形態においては、熱交換器のＵ字形銅管が閉じた側に、Ｕ字形銅管に沿った立面部と、立面部と対向して前記Ｕ字形銅管を挟持固定するために弾性を有するアームと、Ｕ字形銅管を固定するツメを設けた端板を脱着可能に設置して構成することにより、簡単な構造で端板だけを交換可能としてロスコストを削減し、組立や市場での補修を容易にすることができる。   As described above, in the present embodiment, on the side where the U-shaped copper tube of the heat exchanger is closed, the U-shaped copper tube is opposed to the rising surface portion along the U-shaped copper tube and the rising surface portion. It is possible to replace only the end plate with a simple structure and to reduce the loss cost by installing and detaching the end plate provided with an elastic arm to clamp and fix the U-shaped copper tube with a claw And can be easily assembled and repaired in the market.

A fixing claw 12e is provided between the inner side surface and the flat portion.

以上のように構成された分離型空気調和機の室外ユニットについて、端板１２は、熱交換器１０からの簡単な着脱機能を有したまま、銅管の保持力を保ちつつ、端板の形状を小さくして材料を削減できる。   Regarding the outdoor unit of the separation type air conditioner configured as described above, the end plate 12 has the shape of the end plate while maintaining the holding force of the copper tube while having a simple attachment / detachment function from the heat exchanger 10. Can reduce the material.

以上のように、本実施の形態においては、熱交換器が複数列により構成される場合、最も外側の列に保持されるＵ字形銅管数が多くなるように端板を構成することにより、端板の形状を小さくしても銅管の保持力を保つことで、端板の材料を削減できより安価で組み立てやすい室外ユニットを実現することができる。   As described above, in the present embodiment, when the heat exchanger is configured by a plurality of rows, by configuring the end plate so that the number of U-shaped copper tubes held in the outermost row is increased, Even if the shape of the end plate is reduced, by maintaining the holding force of the copper tube, it is possible to reduce the material of the end plate and realize an outdoor unit that is cheaper and easier to assemble.
