した点等に特徴がある。FIGS. 3 and 4 show the outdoor heat exchangers 3a and 3a.
b shows another embodiment, and the outdoor heat exchanger 13 of this embodiment has a plurality of pipes 13a through which a refrigerant passes, which is bent substantially in an L shape, and a plurality of pipes mounted on the outer periphery of the pipes 13a. It is characterized in that the width of the fin 13b in the width direction is wider than that of the conventional example.

１３の軸方向両端部を、Ｕ字状のベンド管により隣り合
うもの同士を接続して１本の蛇管に構成している。That is, the outdoor heat exchanger 13 is provided with a plurality of L-shaped pipes 13a through which the refrigerant passes, as shown in FIG. Both ends in the axial direction are connected to each other by a U-shaped bend tube to form a single serpentine tube.

幅方向長さよりも若干拡幅している。The width dimension WF of each fin 13b is, for example, 1.1 times the pitch PP in the direction in which the pipes 13a are juxtaposed, and is larger than the width in the conventional example in which the pipes 13a are provided in one row. It is slightly wider.

The width in the width direction of the conventional outdoor heat exchanger having 3 1/2 / 2 times P and two rows of pipes is twice as large as the width dimension WFO of the conventional example.

（１）式が成立するように設定している。As shown in FIG. 4, the outdoor heat exchanger 13 of this embodiment slightly decenters the central axis Op of the pipe 13a in the L-shaped bending direction with respect to the central axis Of of each fin 13p. The dimensions of each part in FIG. 5 are set so that, for example, the following equation (1) is satisfied.

熱交換することができる。For this reason, as shown in FIG. 4, inside the L-shaped bent portion B of the outdoor heat exchanger 13, it is possible to prevent the adjacent fins 13b, 13b from coming into contact with each other. Even inside the bent portion B, air can be passed through to exchange heat.

【００３７】このとき、外気中の水分がフィン１３ｂの
外表面で結露し、さらに、凍結して着霜すると、熱交換
能力が低下する。At this time, if the moisture in the outside air is condensed on the outer surface of the fin 13b, and further freezes and forms frost, the heat exchange capacity is reduced.

し、除霜の必要性も低下する。However, the outdoor heat exchanger 13 of this embodiment
Increases the outer surface area by increasing the width dimension WF of the fin 13b to be larger than the fin width WFO dimension of the single-row pipe type conventional outdoor heat exchanger. And the fin temperature increases. For this reason, dew condensation and freezing of the fins 13b are reduced, and the necessity of defrosting is also reduced.

とができる。Further, even when frost is formed on the outer surface of the fin 13b, the thickness of the frost is small because the area of the outer surface of the fin 13b is larger than that of the conventional example. For this reason, since the decrease in the amount of air passing through the outdoor heat exchanger 13 can be suppressed to a low level, the decrease in heat exchange capacity is also small, and the heating operation can be performed for a long time. In other words, the frequency of the defrosting operation can be reduced to increase the heating capacity or efficiency.

低下する。Such an effect can be obtained with a conventional two-row pipe type heat exchanger in which the width of the fins is widened. In this conventional example, two rows of pipes are heated during the defrosting operation to melt frost. Since it is necessary, the amount of heat required for defrosting increases rather, and the defrosting operation time becomes longer. Since the heating operation is interrupted during the defrosting operation, the heating capacity or efficiency is reduced.

In No. 3, since there is only one pipe row, there is no disadvantage of such a conventional two-row pipe type.

換効率を向上させると共に、静かな運転を確保できる。As described above, according to the present invention, the outdoor heat exchanger is entirely curved so that the fins of the outdoor heat exchanger are directed to the outdoor fan, and the central partition is provided with a guide for the ventilation path. As a result, it is possible to guide a smooth wind flow, improve heat exchange efficiency, and ensure quiet operation.

This can prevent the heat exchange ability from lowering.
