Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outdoor unit of an air conditioner, and more particularly to a structure in which a heat exchanger can be effectively cooled by drain water during a cooling operation to enhance a splash effect.
[0002]
[Prior art]
A conventional outdoor unit of an air conditioner is compressed on a base 1 by a partition plate 2 erected on the base 1 as shown in FIG. 1, FIG. 3 (A) and FIG. 3 (B), for example. The chamber is partitioned into a heat exchanger chamber having a recessed portion 3 for storing drain water, and a compressor 4 is provided in the compressor chamber, and is parallel to the recessed portion 3 of the heat exchanger chamber at equal intervals. The heat exchanger 5 includes a plurality of fins 5a arranged in parallel and a heat transfer tube 5b orthogonal to the fins 5a, and a lower part of the fin 5a is immersed in the drain water during cooling operation. An air blower 7 composed of an air blowing fan 7a and a fan motor 7b facing each other is provided, and an outer cylinder 9 having a blow grill 8 that faces the air blower 7 is attached to the base 1, and the heat exchange is performed by the drain water. The heat of the heat exchanger 5 is obtained by the so-called splash effect that the cooler 5 is cooled. The configuration was such that the exchange efficiency was improved.
[0003]
However, since the thermal conductivity of the fin 5a soaked in drain water is insufficient, the splash effect could not be sufficiently mentioned.
Further, as shown in FIG. 3B, for example, as shown in FIG. 3B, the fin 5a is formed in a substantially rectangular shape by being cut from the cutting portion c, and therefore, as indicated by a dashed arrow d ′ shown in FIG. In addition, the air permeability of the upper end portion close to the outer body 2 is deteriorated, causing the heat exchange efficiency of the heat exchanger 5 to deteriorate.
[0004]
[Problems to be solved by the invention]
In the present invention, in view of the above problems, an object of the present invention is to provide an outdoor unit for an air conditioner that can effectively cool a heat exchanger with drain water during cooling operation to enhance a splash effect. And
[0005]
In order to solve the above problems, the present invention divides a compressor chamber and a heat exchanger chamber having a recessed portion for storing drain water by a partition plate standing on a base, and compresses the compressor chamber. On the other hand, a heat exchanger that is affected by the drain water is provided on the recessed portion of the heat exchanger chamber, a blower is provided opposite the heat exchanger, and the blower faces the base. In an outdoor unit of an air conditioner formed by attaching an outer trunk provided with a blowout grill,
The heat exchanger, the lower end of one side in the longitudinal direction, and a projection projecting from the same side outward, the upper end portion of one side of the longitudinal direction, and a notch which notch from the same side inward An L-shaped upper cut formed continuously from the upper end to the lower end of a single rectangular plate so that the protruding portion and the cutout portion are continuously formed in opposite directions in the vertical direction. Cut into two left and right by cutting a cutting portion consisting of a portion, an L-shaped lower cutting portion formed from the lower end to the upper end, and a central cutting portion connecting the upper cutting portion and the tip of the lower cutting portion. A plurality of fins formed simultaneously are arranged.
[0006]
Moreover, it is the structure which formed the notch part continuously in the upper end part of the fin which comprises the said heat exchanger.
[0007]
Moreover, the fin which comprises the said heat exchanger is equipped with the notch part corresponding to the said extension part, and becomes a structure currently shape | molded simultaneously by one board | plate material.
[0008]
Furthermore, the heat exchanger has a configuration in which the cutout portion is disposed on the leeward side.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described as examples based on the accompanying drawings.
FIG. 1 is an exploded perspective view of an outdoor unit of an air conditioner according to the present invention (and a conventional example), FIG. 2 is an explanatory view of a main part of the outdoor unit of the air conditioner according to the present invention, and (A) is a heat exchanger. (B) is a top view which shows the fin of a heat exchanger.
[0010]
In the figure, 1 is a base constituting an outdoor unit of an air conditioner according to the present invention, 2 is a partition plate which is erected on the base 1 and divides the base 1 into a compressor chamber and a heat exchanger chamber. 3 is a recessed portion for collecting drain water provided on the base 1, 4 is a compressor placed in the compressor chamber on the base 1, and 5 is on the recessed portion 3 of the heat exchanger chamber. The heat exchanger is configured with a large number of fins 5a arranged in parallel at equal intervals and a heat transfer tube 5b orthogonal thereto, and the lower part of the fins 5a is immersed in the drain water during cooling operation. , 7 is a blower comprising a blower fan 7a and a fan motor 7b facing the heat exchanger 5, 6 is a fan ring provided along the outer shape of the blower fan 5a, and 9 is attached to the base 1. , An outer body provided with a blow-out grill 8 that faces the blower 7.
[0011]
Next, in the outdoor unit of the air conditioner having the above-described configuration, a structure in which the heat exchanger 5 can be effectively cooled by the drain water during the cooling operation so that the splash effect can be enhanced will be described below. To do.
[0012]
As shown in FIG. 2 (A), the fin 5a constituting the heat exchanger 5 is continuously formed with a protruding portion a protruding outward from one side at a lower end portion on one side in the longitudinal direction . By this protrusion a, the contact area with the drain water is expanded, the heat dissipation effect is promoted, and the heat exchange efficiency of the heat exchanger can be improved.
[0013]
Fins 5a constituting the heat exchanger 5, the end portion on one side in the longitudinal direction, as shown in FIG. 2 (A), the notch b is continuously formed to notch from one side inwardly . This notch b improves the air permeability of the upper end portion close to the flange of the outer body 2 as indicated by an arrow d indicated by a broken line, and the heat exchange efficiency of the heat exchanger can be improved.
[0014]
The fins 5a constituting the heat exchanger 5 are formed by pressing one plate material at the same time, and the protrusions a and the notches b are continuous in opposite directions in the vertical direction. As shown in FIG. 2B, an L-shaped upper cut portion is formed from the upper end to the lower end of a single rectangular plate, and the lower end is formed toward the upper end. The L-shaped lower cutting part and the cutting part c consisting of the upper cutting part and the central cutting part connecting the tips of the lower cutting parts are cut and formed into two pieces on the left and right at the same time.
