Problems solved by technology

[0007] However, in the above-mentioned conventional structure, on one heat exchanger, the louvers of the flat fins (hereinafter referred to as "radiation fins") must be different in the upper part 104 of the heat exchanger and the lower part 105 of the heat exchanger. variety of heat exchangers, reducing the productivity of one heat exchanger
In addition, due to the simple shape of the fin louvers, the area of ​​the fin cannot be enlarged and the heat exchange rate of the fin cannot be sufficiently ensured.
In addition, since the cut hole is slightly larger than the louver surface, the whistling sound generated when passing between the heat sinks is increased, and there is a problem that the noise becomes louder.
[0008] In addition, due to the fin-to-fin spacing, the change in the height of the louvers is limited, and it is difficult to achieve a height difference that can sufficiently generate air pressure loss. Therefore, there is a problem of insufficient uniformity of the wind speed at the front of the heat exchanger.

Embodiment 1

[0038] Hereinafter, an air conditioner according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4 . Fig. 1 is a basic configuration diagram of an outdoor unit of an air conditioner according to Embodiment 1 of the present invention, and Fig. 2 is a schematic top sectional view of the air conditioner.

[0039] In Figures 1 and 2, inside the frame body 1 of the outdoor unit, a compressor 2, an upper layer heat exchanger 3 (hereinafter referred to as "upper layer heat exchanger 3") and a lower layer heat exchanger are arranged. 4 (hereinafter referred to as "lower layer heat exchange 4") and the refrigeration cycle system composed of blower 5, which is arranged in the above-mentioned frame body 1 in the vertical direction and can connect the machine room 6 where the above-mentioned compressor 2 is installed and the machine room 6 where the compressor 2 is installed. A partition 8 separating the heat exchange chambers 7 of the upper heat ex...

Embodiment 2

[0045] Fig. 5 is a perspective view of a heat exchanger of an air conditioner according to Embodiment 2 of the present invention. In addition, the same code|symbol is used for the same part as the above-mentioned embodiment, and the description is abbreviate|omitted.

[0046] In this embodiment, the diameters of the pipelines 13 and 14 that are arranged in the upper heat exchanger 3 and the lower heat exchanger 4 that are overlapped in two layers and constitute a part of the refrigeration cycle pipeline are different. Specifically, the inner tubes of the upper heat exchanger 3 The diameter of the passage 13 is set to be larger than the diameter of the pipeline 14 in the lower heat exchanger 4 .

[0047] According to the above-mentioned structure, the air pressure loss when passing through the heat exchanger is increased by the thick pipe 13 on the upper heat exchange 3, and is reduced by the thin pipe 14 on the lower heat exchange 4. As a result, the front The wind speed is s...

Embodiment 3

[0049] Fig. 6 is a basic structural diagram of an outdoor unit of an air conditioner according to Embodiment 3 of the present invention. In addition, the same code|symbol is used for the same part as the above-mentioned embodiment, and the description is abbreviate|omitted.

[0050] In this embodiment, as shown in FIG. 6 , a baffle plate 15 that acts as a ventilation resistance to a part of the upper heat exchanger 3 is installed near the inner surface of the upper portion of the upper heat exchanger 3 .

[0051] According to the above-mentioned structure, the air volume when passing through the upper heat exchanger 3 with an accelerated wind speed close to the blower 5 is suppressed due to the baffle plate 15 as a ventilation resistance, and a certain amount of the suppressed air volume is used to increase the air volume supplied to the lower heat exchanger. 4 air volume parts, as a result, it is not affected by the poor shape of the heat exchanger fins 9, and the uniformity ...

Abstract

This air conditioner comprises a heat exchanger formed of an upper stage heat exchanger 3 and a lower stage heat exchanger 4 stacked in two stages and a blower 5 installed on a casing top surface part vertically to the fins 9 of the heat exchanger and discharging the outside air from the casing upper part through the heat exchanger. A louver forming a ventilation resistance is installed over the fin 9 of the heat exchanger 3, and a corrugate smaller in the ventilation resistance than the louver is formed on the fins 11 of the lower stage heat exchanger 4 so that an air pressure loss becomes larger on the upper stage heat exchanger 3 than on the lower stage heat exchanger 4. Thus, the air velocity at the front face of the heat exchanger can be uniformized between the upper stage heat exchanger 3 and the lower stage heat exchanger 4. Also, since a conventional cutout hole is absent, the occurrence of the air noise by the air passing between the fins 9 and 11 can be suppressed.
