While standing indoor side heat exchanger 16 close to the inside of,
The outdoor heat exchanger 17 is placed close to the inside of the rear opening grill 15.
A fan motor 20 that drives an indoor fan 18 and an outdoor fan 19 made of, for example, a propeller fan together is installed between the both 16 and 17, and a compressor 21 is arranged on the side thereof.
室外ファン19はスリンガリング22を取り付けており、
ドレンパン23内のドレン24はこのスリンガリング22の回

る。As shown in FIG. 1, the outdoor heat exchanger 17 is provided with fins 26, which are made of a plurality of thin plates, on the outer peripheral surface of a heat exchange tube 25 having a serpentine tube through which a refrigerant passes, at a required pitch in the axial direction. , The heat exchange capacity of the heat exchange tube 25 is improved.
また、室外側熱交換器17の軸方向端部、つまりＵ字状
折返し端部には第４図で示す端板27を取り付けている。An end plate 27 shown in Fig. 4 is attached to the axial end of the outdoor heat exchanger 17, that is, the U-shaped folded end.
端板27は第７図で示す従来の端板７と同様のバーリン
グ孔８内に熱交換管25のＵ字状端部を挿通してカラー９
により確実に保持している。The end plate 27 has a U-shaped end portion of the heat exchange tube 25 inserted into the burring hole 8 similar to the conventional end plate 7 shown in FIG.
Holds securely by.
しかし、第４図のＩ部に示すように端板27の下部では
その内面に沿ってバーリング孔８のカラー９…を切欠す
ることにより、カラー９が無い通し穴28に形成してい
る。However, as shown in Part I of FIG. 4, the collar 9 of the burring hole 8 is cut out along the inner surface of the lower portion of the end plate 27 to form the through hole 28 without the collar 9.
そして、この通し穴28を設けた端板27の一部の内面
と、すぐ隣のフィン26の側面とを密着させて、両者26,2
7間の間隙を閉じている。Then, the inner surface of a part of the end plate 27 provided with the through hole 28 and the side surface of the fin 26 immediately next to each other are brought into close contact with each other, and both 26, 2
The gap between 7 is closed.
このために、端板27のバーリング孔８と通し穴28との
境界部ではカラー９が除去された分だけ、隣りのフィン
26が端板27の内面側へ急傾斜するように折曲される。Therefore, since the collar 9 is removed at the boundary between the burring hole 8 and the through hole 28 of the end plate 27, the adjacent fins are adjacent to each other.
26 is bent so as to incline toward the inner surface of the end plate 27.
