れる。In such a heat exchanger, since the refrigerant flows in parallel in units of heat exchange groups, the number of parallel flows (the number of passes) is increased to increase the flow path resistance. In order to reduce the number, the height dimension of the heat exchanger is inevitably increased, and the heat exchanger cannot be increased in size. In addition, as the size of the heat exchanger becomes larger, it is inevitable that the blower also becomes larger. On the other hand, imbalance of the air flow in the heat exchanger tends to occur, and it may not be possible to expect an increase in the heat exchange rate according to the size increase. Conceivable.

ス約半分づつの状態となる。In other words, if the above-mentioned refrigerant flow is paraphrased (simply referred to), it means that the flow directions of the refrigerants flowing in parallel are made to face each other as shown in FIG. 4, whereby the heat exchange rate of the heat exchange group A is changed. Can be made substantially uniform. Figure 5
FIG. 3 is an explanatory view schematically showing the change of the refrigerant. The heat exchanger 6 includes a heat exchange pipe 50 on the front side with the inlet end 21a 1 facing upward and a heat exchange pipe on the center side with the inlet end 21a 3 facing downward. It is cut and developed between 60 and 60. As can be seen from this figure, in the upper part of the heat exchange group A, the refrigerant in the front heat exchange pipe 50 is liquid 51 because almost no heat is exchanged, whereas in the center side heat exchange pipe 60. Since the refrigerant of (3) is on the outlet side, the heat exchange is almost completed and it is in a gaseous state 61. In this way, the liquid refrigerant 51 and the gaseous refrigerant 61 are mixed above the heat exchange group A. This mixed state is the same below the heat exchange group (inside the heat exchange pipe 50 on the front side, the gas state 52, and inside the heat exchange pipe 60 on the center side, the liquid state 62). At the center of the heat exchange group, about half of the liquid gas is in each heat exchange pipe.

However, such a state is the same in any of the heat exchange groups B and C. Therefore, the heat exchange rate can be improved. Moreover, with reference to FIG. 3, at any of the ends (upper end and lower end) of the heat exchange groups A, B, C, the outlet end and the inlet end of the heat exchange pipes of different (parallel flow) flow paths are connected.
