率を上げるためである。The operation of the conventional heat exchanger for a dehumidifier configured as described above will be described below with reference to the drawings. During operation, the heat exchanger 1 for a dehumidifier is fixed to a heat transfer tube 2 through which a refrigerant flows, with a flat fin 3 penetrating therethrough. As shown in FIG. 2, the heat exchanger 1 for a dehumidifier has a large number of flat fins 3 stacked.
The inflow air 7 flows between the heat transfer tube 2 and the flat fins 3 and exchanges heat with the refrigerant flowing through the heat transfer tube 2, and the moisture in the air cooled and condensed by the evaporator unit 5 is dehumidified. At this time, as shown in FIG. 3, the flat fin 3 is often provided with a slit 4 between the evaporator section 5 and the condenser section 6. This is the evaporator section 5
This is for suppressing the heat exchange between the refrigerant of the condenser section 6 and the refrigerant, and increasing the dehumidifying efficiency.

で成形することができ、スリット成形金型は必要ない。During operation, the heat exchanger 1 for a dehumidifier is fixed to a heat transfer tube 2 through which a refrigerant flows, through which flat fins 3 penetrate. As shown in FIG. 1, the heat exchanger 1 for a dehumidifier has a large number of flat fins 3 stacked. The inflow air 7 flows between the heat transfer tube 2 and the plate-like fins 3 and exchanges heat with the refrigerant flowing in the heat transfer tube 2, and the moisture in the air cooled and condensed by the evaporator unit 5 is dehumidified. At this time, the evaporator section 5 and the condenser section 6
The heat transfer tube removing portion 8 is provided between the heat transfer tube and the heat transfer tube. Thereby, heat exchange between the refrigerants of the evaporator unit 5 and the condenser unit 6 can be suppressed, and the dehumidification performance can be improved. A similar effect can be obtained by providing a slit in the flat fin 3, but in this case, a slit forming die is required. In the embodiment of the present invention, it can be manufactured by the same method as a general fin-and-tube heat exchanger, and a slit forming die is not required. Further, regarding heat exchange between the refrigerants in the second row portion of the evaporator section 5 and the third row portion of the condenser section 6, heat conduction can be suppressed by separately molding the fins. Also in this case, it can be formed by a general fin-and-tube heat exchanger manufacturing method, and a slit forming die is not required.

容積内で、高い除湿性能を得ることができる。In the embodiment of the present invention, the inflow air 7 flows in from the evaporator section 5. The upstream portion of the evaporator section 5 is divided into the downstream evaporator section 5 and the condenser section 6. The evaporator section 5 is configured to be two steps lower than the mixed portion, and the evaporator section 5 is provided below the second row. As a result, the air resistance of the upper two stages of the heat exchanger 1 for the dehumidifier is reduced, the wind speed of the lower eight stages is relatively reduced, and the length of the evaporator unit 5 in the air flow direction is reduced by the length of the condenser unit 6. Can be increased with respect to the ratio. Due to the synergistic effect of reducing the wind speed by this bypass and increasing the length of the evaporator section 5 in the airflow direction, the heat exchanger for the dehumidifier of the present embodiment can obtain high dehumidifying performance within a compact volume. .
