In the above-described heat exchange unit, the side panel is generally formed of a metal plate, similarly to the bottom plate. Therefore, even if a force is applied to the joint between the bottom plate and the side panel, Since it was strong, it was hard to be damaged. However, when the side panel is made of a synthetic resin in order to improve the aesthetic appearance or to form a complicated shape, for example, when a force is applied from the upper part, there is a possibility that the joint portion may be easily damaged.

[0004] The present invention provides a heat exchange unit in which a joint portion of an exterior body is hardly damaged.

[0005]

According to a first aspect of the present invention, an exterior body is formed by a synthetic resin side panel or a bottom plate having a rising portion. In a heat exchange unit containing frozen parts such as a container, a rising portion facing upward is formed on the bottom plate, and a fitting rib extending obliquely downward from the rear surface is provided on the rear side of the side panel. A guide rib is provided for connecting the upper surface of the rib to the rear surface above the rib, and the lower end of the guide rib and the lower end of the fitting rib are substantially aligned, and the guide rib projects from the inner surface. The size is set to be larger than the protrusion size of the fitting rib.

According to a second aspect of the present invention, there is provided a heat exchanging device comprising a front panel, a side panel, a bottom plate having a rising portion, and the like made of a synthetic resin, and a refrigerating component such as a heat exchanger housed in the outer package. In the unit, a rising portion facing upward is formed on the bottom plate, and a fitting rib extending obliquely downward from the rear surface is provided on the rear surface of the side panel, and the upper surface of the rib and the upper portion above the rib are provided. A guide rib connecting the back surface is provided, and a lower end of the guide rib and a lower end of the fitting rib are substantially aligned with each other, and a projecting dimension of the guide rib from the inner surface is made larger than a projecting dimension of the fitting rib. It is set to be large.

FIG. 2 shows the rear side of the front plate 4, which is formed by injection molding using a synthetic resin material. Reference numerals 4A and 4B denote ribs protruding rearward. The ribs 4A and 4B are formed with two ribs 4A extending vertically and two ribs 4B extending left and right. The rib 4A has a gas channel portion 4C formed therein (see FIG. 3), and since this gas channel portion is formed, a small depression called sink mark is unlikely to be formed on the surface of the front plate. . In addition, 4H is a blowing grill, 4D is a fitting rib, 4E.
Are guide ribs, and these ribs 4D and 4E are provided on the lower side of the substantially central portion of the front plate 4.

Further, 4F shown in FIG. 3 is a curved portion, and 4G is a screw fixing portion.

FIGS. 4 and 5 show the relationship between the bottom plate 5 and the front plate 4. The lower end of the rib 4A is a rising portion 5 around the bottom plate 5. As shown in FIG.
A is placed at the tip of A. In addition, the rising part 5 on the center side
A is a fitting rib 4 when assembled as specified.
D is fitted to the fitting portion 4J. The fitting rib 4D is
It extends obliquely downward from the rear surface 4K of the front plate 4. The guide rib 4D connects the surface on the opposite side of the inner surface of the fitting rib to the back surface 4K. Further, the lower end of the guide rib 4E and the lower end of the fitting rib 4D are made substantially coincident with each other, and the projecting dimension of the guide rib from the rear surface 4K is set to be larger than the projecting dimension of the fitting rib 4D. .

FIG. 6 shows the vicinity of the blind plate 16, which has a stepped shape so that its lower end is located between the rising portion 5A of the bottom plate 5 and the front plate 4, and Even if it is rained, rain water or the like is guided outside the machine room (outside the bottom plate), so that rain water does not enter the machine room.

The motor base 8 shown in FIGS. 7 and 8 is provided with a mounting flange 8A at the upper end and a back support 8B for supporting the heat exchanger. Further, a front side support portion 8D is formed by cutting and raising a horizontal portion 8C located above the heat exchanger 6 of the motor base 8. For this reason, the upper part of the heat exchanger is supported by being sandwiched between the front support part 8D and the back support part 8B. 8E is an opening, and 8F is a component code. When the heat exchangers are arranged in two rows as in this embodiment, the front support 8D is cut and raised. For example, when the heat exchanger 6A having a small capacity and one row is arranged, the front support 8D is arranged. The support portion 8G is cut and raised. 8H is a component code for indicating the component when the support portion is cut and raised (see FIG. 9).

The outdoor unit 1 configured as described above has a bottom plate 5.
After the refrigerating parts such as the compressor 13 and the back plate 3 are assembled, the front plate 4 is assembled next. At this time,
The substantially central portion of the front surface of the bottom plate 5 is positioned so as to fit into the fitting portion 4J. At this time, since the guide rib 4E is provided, the rising portion 5A of the bottom plate 5 is
It is prevented from being on the back side from J. If the front side plate 4 is located on the back side of the fitting portion 4J (see the dashed line in FIG. 5), the front plate 4 is greatly curved due to the presence of the guide ribs 4E. Has become. When the rising portion 5A of the bottom plate 5 is fitted into the fitting portion 4J, the lower end of the rib 4A comes into contact with the rising portion 5A of the bottom plate 5. And the screw stopper 4
When the screw is fixed with G, the mounting of the front panel 4 is completed, and when the top panel 2 is mounted, the assembly of the outdoor unit 1 is completed.

Further, in the outdoor unit 1 configured as described above, since the front plate 4 is provided with the ribs 4A and 4B, even if a force is applied to the front plate 4, the front panel 4 may be deformed or broken. It has a structure that is difficult to damage and hard to damage.

When a force is applied to the top plate 2 or the front plate 4 is applied from above, the lower end of the rib 4A hits the rising portion 5A of the bottom plate 5 and receives a force at this portion. The front plate 4 is hardly damaged. Moreover, only the front plate 4 of this exterior body is made of synthetic resin, and other metal exterior bodies (bottom plate 5, back plate 3, top plate 2).
Ribs 4A, 4B
Are formed, and right and left curved portions 4F are formed, so that the strength is improved. In addition, since the fitting rib and the guide rib are connected, even if the metal rising portion 5A hits this portion (fitting portion 4J), it is hardly damaged.

The rib 4A has a gas channel 4
C is formed, and the front side also has a structure in which depressions such as sink marks are unlikely to occur. In addition, the front plate 4 and the bottom plate 5 can be assembled at the front center without using screws. For this reason, there is little possibility that the aesthetic appearance of the surface of the front plate 4 will be reduced.

In this embodiment, the component codes 8F,
8H are provided, and when the cut-and-raised portion 8D is provided, the code 8H indicating a component that is not the component provided with the cut-and-raised portion is made invisible. Parts can be shared except for parts.
