Description

  The present invention relates to an outdoor unit for a refrigeration apparatus.

Conventionally, there is an outdoor unit 503 of an air conditioner as shown in FIGS. 10 and 11 (FIG. 10 is an external perspective view of the outdoor unit 503, and FIG. 11 is a perspective view showing an internal state of the outdoor unit 503. is there). Such a configuration of the outdoor unit 503 is usually employed in an air conditioner that requires a relatively large heat exchange capability. In such an outdoor unit 503, an air conditioner (hereinafter referred to as a low-capacity air conditioner) in which the area of the outdoor heat exchanger 530 requires only a relatively small heat exchange capacity due to restrictions on installation space and manufacturing convenience. ) Is expanded by extending the heat exchange panel of the outdoor unit in the height direction. Further, in the outdoor unit of the low-capacity air conditioner, the wind speed distribution of the air passing through the heat exchange panel is sufficiently uniformed by one propeller fan, but in this outdoor unit 503, the outdoor heat exchanger 530 is in the height direction. Therefore, the wind speed distribution is not sufficiently uniformed by the same single propeller fan.

For this reason, in the outdoor unit of this refrigeration apparatus, the heat exchanger takes a form in which at least one of the upper part and the lower part of the heat exchanger provided in the conventional outdoor unit is bent forward. . Therefore, the outdoor unit of the refrigeration apparatus can be made compact in the height direction without reducing the heat exchange area.

[Features of outdoor unit of air conditioner]
(1)
In the outdoor unit 3 of the air conditioner 1 according to the present embodiment, the rear heat exchange part 30a of the central heat exchange panel 30A is provided along the rear surface (surface perpendicular to the depth direction Y). Further, the upper heat exchange panel 30B is provided to be inclined upward Z1 from the upper part of the rear heat exchange part 30a of the central heat exchange panel 30A toward the front Y1, and the lower heat exchange panel 30C is provided on the rear surface of the central heat exchange panel 30A. It is provided so as to incline downward Z2 from the lower part of the heat exchange part 30a toward the front Y1. The propeller fan 38 supplies air to the rear heat exchange unit 30a, the upper heat exchange panel 30B, and the lower heat exchange panel 30C of the central heat exchange panel 30A. For this reason, in the outdoor unit 3 of this air conditioning apparatus 1, the outdoor heat exchanger 30 takes the form which bent the upper part and lower part of the heat exchanger provided in the conventional outdoor unit ahead. It becomes. Therefore, the outdoor unit 3 of the air conditioner 1 is made compact in the height direction without reducing the heat exchange area. That is, the outdoor unit 3 of the air conditioner 1 is made compact in the height direction without significant decrease in heat exchange capacity.

(2)
In the outdoor unit 3 of the air conditioner 1 according to the present embodiment, the central heat exchange panel 30A employs the louvered fin 70, the upper heat exchange panel 30B employs the slit fin 80, and the lower heat exchange panel 30C employs the flat fin 90. Is done.
In the outdoor unit 3 of the air conditioner 1, the rear heat exchange part 30a of the central heat exchange panel 30A is arranged on a surface orthogonal to the rotation axis L of the propeller fan 38 that is an axial fan. Therefore, in the outdoor unit 3 of the air conditioner 1, the amount of ventilation in the upper heat exchange panel 30B and the lower heat exchange panel 30C is smaller than the amount of ventilation in the rear heat exchange unit 30a. For this reason, in the outdoor unit 3 of the air conditioner 1, the heat exchange capability of the upper heat exchange panel 30B and the lower heat exchange panel 30C is inferior to the heat exchange capability of the rear heat exchange unit 30a. However, the louvered fin 70 usually has a higher ventilation resistance than the slit fin 80, the flat fin 90, or the like. For this reason, in the outdoor unit 3 of this air conditioning apparatus 1, the ventilation resistance in the rear surface heat exchange unit 30a is increased, and the heat exchange capability of the rear surface heat exchange unit 30a is improved. Therefore, in the outdoor unit 3 of the air conditioner 1, the heat exchange capacity of the heat exchange panels 30A, 30B, and 30C as a whole approaches the heat exchange capacity of the heat exchanger of the conventional outdoor unit.

  Further, in the outdoor unit 3 of the air conditioner 1, the upper heat exchange panel 30B is inclined, so that the dew condensation water easily falls on the propeller fan 38 or the like. However, the slit fin 80 has a characteristic of cutting the condensed water and guiding it in the longitudinal direction of the main body plate 82 along the raised portion 83. For this reason, in the outdoor unit 3 of the air conditioner 1, it is possible to suppress the possibility that the condensed water generated in the upper heat exchange panel 30B falls on the propeller fan 38 or the like.

  In the outdoor unit 3 of the air conditioner 1, the dew condensation water generated in the upper heat exchange panel 30B and the central heat exchange panel 30A is guided to a drain pan or the like via the lower heat exchange panel 30C. For this reason, in the outdoor unit 3 of the air conditioner 1, the amount of ventilation in the lower heat exchange panel 30C may be smaller than that of the other heat exchange panels 30A and 30B due to condensed water. However, the flat fin 90 is superior in drainage compared to the louvered fin 70 and the slit fin 80. For this reason, in the outdoor unit 3 of this air conditioner 1, it is suppressed that the ventilation rate in the lower heat exchange panel 30C decreases remarkably.

(3)
In the outdoor unit 3 of the air conditioner 1 according to the present embodiment, the propeller fan rotor 40 overlaps with the rear heat exchange part 30a of the central heat exchange panel 30A when viewed from the front, but the upper heat exchange panel 30B and the lower heat It does not overlap the replacement panel 30C. For this reason, in the outdoor unit 3 of the air conditioner 1, the wind speed distribution in the rear heat exchange unit 30a, the upper heat exchange panel 30B, and the lower heat exchange panel 30C can be stabilized.

(4)
In the outdoor unit 3 of the air-conditioning apparatus 1 according to the present embodiment, the central heat exchange panel 30A has a side heat exchange unit 30b. For this reason, in the outdoor unit 3 of the air conditioner 1, a large heat exchange area is secured.

(6)
In the outdoor unit 3 of the air conditioner 1 according to the present embodiment, the upper surface suction grill is provided on the upper surface panel 50a. For this reason, in the outdoor unit 3 of the air conditioner 1, more air can be supplied to the upper heat exchange panel 30B.
(7)
In the outdoor unit 3 of the air conditioner 1 according to the present embodiment, the central heat exchange panel 30A, the upper heat exchange panel 30B, and the lower heat exchange panel 30C are manufactured separately. As a method of making a conventional outdoor heat exchanger into the shape of the outdoor heat exchanger 30 as shown in the present embodiment, a plurality of heat exchange panels 30A, 30B, and 30C are used as shown in the present embodiment. A method of assembling or a method of manufacturing a heat exchange panel having a shape as shown in FIG. 12 and bending it along a broken line can be considered. The former method is advantageous over the latter method in terms of attachment of heat dissipating fins, but is disadvantageous in that more support members are required.

(8)
The outdoor unit 3 of the air conditioner 1 according to the present embodiment is made more compact in the height direction than the conventional double fan type outdoor unit.

It may be. That is, the arrangement interval of the radiating fins of the central heat exchange panel 30A is made narrower than the arrangement interval of the radiating fins of the upper heat exchange panel 30B and the lower heat exchange panel 30C. Moreover, if the arrangement | positioning space | interval of the radiation fin of the center heat exchange panel 30A is made narrower than the arrangement | positioning space | interval of the radiation fin of the heat exchanger of the conventional outdoor unit, heat exchange capability higher than the heat exchanger of the conventional outdoor unit will be obtained.
