Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger fixing device provided in an outdoor unit of an air conditioner.

[0002]

2. Description of the Related Art As an outdoor unit of a conventional air conditioner, there is one disclosed in Japanese Utility Model Laid-Open No. 59-110873.

An example of the outdoor unit of the conventional air conditioner described above will be described below with reference to the drawings.

In FIGS. 4 and 5, 1 and 2 are L-shaped laminated heat exchanger bodies, 3 is a hairpin protruding from the end face thereof,
Reference numeral 4 is a heat exchanger body, 5 is each end face plate, 6 is a common S-shaped connecting plate which is overlapped so as to straddle these end face plates 5, and 7 is a mounting screw for the connecting plate 6.

In the conventional structure having the above-mentioned structure, the gap 8 between the L-shaped laminated heat exchanger bodies 1 and 2 after the connection varies due to the variation in the screw hole size of the end plate 5 and the connection plate 6. It happened. When mounting the mounting screws 10 on the connecting plate 6 and the unit base 9, the end plates 5 of the L-shaped laminated heat exchanger bodies 1 and 2 must be flush with each other. A particularly precise technique is required for the L-shaped bending of the laminated heat exchanger bodies 1 and 2, and the number of assembling steps is also high.

[0006]

However, since the conventional L-shaped laminated heat exchanger bodies 1 and 2 are fixed as described above, the L-shaped laminated heat exchanger bodies 1 and 2 are fixed.
Due to the variation in the gap 8 after assembly between the units, a chattering noise is generated when the outdoor unit vibrates significantly, the mounting screws 10 at each assembly do not match, and each L-shaped laminated heat exchanger body The L-shaped bending of Nos. 1 and 2 requires high precision, requires a high processing cost, and requires a lot of man-hours for the mounting screw 10.

The present invention has been made in order to solve the above-mentioned problems, and it fixes both of the L-shaped laminated heat exchanger bodies to be laminated with a certain gap between them. The purpose is to eliminate the need to align the L-shaped laminated heat exchanger bodies in a plane.

[0008]

In order to solve the above problems, in the fixing device of the heat exchanger in the air conditioner of the present invention,
L-shaped laminated heat exchanger having a plurality of square holes in the flange portions of both end face plates, and L-shaped having a plurality of engaging protrusions configured to be engageable with the square holes in the flange portions of both end face plates -Shaped laminated heat exchanger and a mounting screw for fixing the L-shaped laminated heat exchangers to each other, and aligning the flange portions of the L-shaped laminated heat exchangers with each other into the square holes. When the engaging projections are engaged and held, a predetermined gap is formed between the stacked L-shaped laminated heat exchanger bodies, and the mounting screws are formed in the L-shaped laminated heat exchangers. The flange portions of the L-shaped laminated heat exchangers are fixed to each other in a state where the flange portions of the L-shaped heat exchanger are aligned and the engaging protrusions are engaged and held in the square holes.

[0009]

In the fixing device for the heat exchanger in the air conditioner of the present invention, the engaging projections are engaged and held in the square holes to provide a gap between the L-shaped laminated heat exchanger bodies which are laminated, Since it is fixed by the flanges of both end face plates, both L-shaped laminated heat exchanger bodies can be fixed with a certain gap provided between the laminated L-shaped laminated heat exchanger bodies. It is possible to eliminate the need to align the surfaces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An outdoor unit for an air conditioner according to an embodiment of the present invention will be described below with reference to the drawings. In addition,
The same components as those of the related art will be denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, 11 is a plurality of square holes provided in the flange portion of both end face plates 5'of the L-shaped laminated heat exchanger 1 ', and 12 is an L-shaped laminated heat exchanger 2'. A plurality of engaging protrusions 9 provided on the flange portions of the both end face plates 5'are unit bases. 14 is a mounting screw.

In this embodiment, when the flanges of both L-shaped laminated heat exchangers 1'and 2'are aligned and the engaging projections 12 are engaged and held in the square holes 11, the L-shaped laminated heat exchangers are stacked. It is configured such that a predetermined gap 8 is formed between the main bodies of the laminated heat exchangers 1'and 2 '.

First, an L-shaped laminated heat exchanger body 1'is shown in FIG.
After mounting with a mounting screw 10 at a predetermined position on the unit base 9 shown in FIG. 2, the engaging projections 12 on the flange portions of both end face plates 5 ′ of the L-shaped laminated heat exchanger body 2 ′ are formed into the L-shaped laminated heat exchanger. The L-shaped laminated heat exchanger body 1 ', which is engaged and held in the square holes 11 of the flange portion of the both end surface plates 5'of the body 1', and is laminated
After the flange portions of both end face plates 5'abut with each other with a gap 8 formed between 2 ', fix the flange portions of both L-shaped laminated heat exchangers 1', 2'with mounting screws 14. , The L-shaped laminated heat exchanger body 2'is attached to the unit base 9 at a predetermined position with the screws 10a.

As a result, the two L-shaped laminated heat exchanger bodies 1 ', 2'are both L-shaped with a gap 8 formed between the L-shaped laminated heat exchanger bodies 1', 2 '. The laminated heat exchanger bodies 1 ′ and 2 ′ are fixed to each other, and both L-shaped laminated heat exchanger bodies 1 ′ and 2 ′ are fixed to the unit base 9.

Referring to FIG. 2, the gap 8 between the L-shaped laminated heat exchanger bodies 1'and 2'in a laminated state is defined by the L-shaped laminated heat exchanger bodies 1'and 2'both end face plates 5 '. By fixing the flanges to each other, the flanges are always kept at a constant distance, and the L-shaped laminated heat exchanger bodies 1'and 2'are both L-shaped due to the square holes 11 and the engaging projections 12 in the flanges of the end plates 5 '. In order to connect the L-shaped laminated heat exchanger bodies 1'and 2'and fix the flange portions of the both end face plates 5'of the L-shaped laminated heat exchanger bodies 1'and 2'with the mounting screws 14, The end faces of the L-shaped laminated heat exchanger bodies 1'and 2'need not be flush with each other.

[0016]

As described above, according to the present invention, one end face plate having a plurality of square holes is provided in the flange portion for one L-shaped laminated heat exchanger, and the other L-shaped laminated heat exchanger is provided. For the exchanger, both end face plates having a plurality of engaging projections configured to be able to engage with the square holes are provided in the flange portion, and the flange portions of both L-shaped laminated heat exchangers are combined to form a square hole. When the engaging projections are engaged with and held by, the L-shaped laminated heat exchanger bodies are laminated so that a predetermined gap is formed between the main bodies. Both L in the state where the flange is aligned and the engaging projection is engaged and held in the square hole.
The flanges of the letter-shaped laminated heat exchanger were fixed with mounting screws.

As a result, a predetermined gap can be provided between the laminated L-shaped laminated heat exchanger bodies,
Even if the outdoor unit vibrates greatly, chattering noise does not occur and both L-shaped laminated heat exchangers are fixed by the flanges of both end plates, so the end surface of the L-shaped laminated heat exchanger body must be the surface. Since it is not necessary to make the number one, the number of assembling steps is reduced, and there is also an effect that the processing such as the L-shaped bending of each L-shaped laminated heat exchanger body does not require high accuracy and the processing cost can be reduced.
