[Problems to be solved by the device]

 In the outdoor unit of the conventional air conditioner heat exchanger, the air that has passed through the fin coil is exhausted by the fan while generating a swirl flow in the outdoor unit, which has a drawback that the air flow cannot be smoothed. In addition, since the motor support and the cover are separate parts, there is a drawback in that the assembly of the parts may vary, and the chip clearance between the fan and the opening of the cover cannot be made too small. Along with that, there was a limit to the wind force. Further, there is a drawback that the heat exchanger becomes thick and it is difficult to make it compact. Therefore, the present invention adopts the following configuration in order to solve the above problems.

[Embodiment of device]

 Next, an embodiment of an outdoor unit of a heat exchanger for air conditioning of the present invention will be described with reference to the drawings. 1 is an exploded perspective view of the outdoor unit of the heat exchanger for air conditioning, FIG. 2 is a schematic sectional view taken along the line II-II of FIG. 1, and FIG. 3 is another outdoor unit of the heat exchanger for air conditioning of the present invention. An embodiment is shown. In the example of FIG. 1, the fin coil 1 has a serpentine shape in which a large number of U-shaped tubes penetrate through a large number of plate fins arranged in parallel with a small gap, and both ends thereof are connected to other tubes. Is formed. The entire vertical surface is formed in a rectangular flat plate shape, and is arranged on the base portion 10. Side members 11 are provided on both sides of the fin coil 1, and the outer periphery of the shroud 6 is fastened and fixed to the side members 11 by bolts or the like. The shroud 6 has a shallow funnel portion 3 connected to the front surface side of the tubular portion 2 integrally or by joining. The funnel portion 3 has a rectangular outer periphery that approximately matches the rectangular shape of the fin coil 1 and has a funnel shape. Then, a mounting flange portion is projectingly provided on at least both sides in the width direction. A bell mouth portion 12 is formed at the rear end of the cylindrical portion 2 so as to expand outward as shown in FIG.

Next, a stay 4 is provided on the inner surface of the tubular portion 2 so as to project toward the center in the radial direction, and a motor mounting portion 5 is integrally provided at the center of the stay 4. The fan motor 7 is arranged on the motor mounting portion 5, and the boss portion of the fan 8 is fixed to the rotation shaft 7a thereof. An operating unit 9 is arranged on a base 10 on the side of the fin coil 1 in the plane direction. The operating unit 9 is composed of a compressor, a solenoid valve and the like. Since the absorption heat exchanger does not require a compressor, it consists of other elements. Next, FIG. 3 is the same as the example of FIG. 1 except that the operating unit 9 is arranged at the lower end of the fin coil 1 in the above embodiment.

[0007]

[Operation and effect of the device]

 Since the outdoor unit of the heat exchanger for air conditioning of the present invention has a structure in which the fan 8 is installed inside the tubular portion 2 of the shroud 6, the air blowing effect in the outdoor unit is large and the air volume is large. Moreover, since the motor mounting portion 5 is provided on the shroud 6 itself, the fan motor 7 is disposed there, and the fan 8 is mounted on the rotary shaft 7a of the fan motor 7, the cylindrical portion 2 The accuracy of assembling the inner surface and the fan 8 can be improved, and the tip clearance can be made as small as possible. Therefore, the air volume in the outdoor unit becomes large. Further, since the outer periphery of the shroud 6 having the fan 8 therein is directly attached to the outer periphery of the fin coil 1, the overall thickness of the outdoor unit can be made as thin as possible, which contributes to the compactness. Further, in the case where the bell mouth portion 12 is formed at the rear end of the tubular portion 2, the air flow passing through the fin coil 1 can be smoothly diffused to the rear of the bell mouth portion 12.
