Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an improvement of the bottom plate of a heat exchange unit.

(b) Conventional technology As an example of the structure of a heat exchange unit,
There is number 127432.

According to this content, a partition plate is installed on the bottom plate of the heat exchange unit, and the bottom plate is divided into a mechanical area where the compressor and four-way valve are placed, and a heat exchange area where the heat exchanger is placed. ing.

(c) Problems to be solved by the invention In such a heat exchange unit, the area of the bottom of the mechanical area is small, and the heavy compressor is fixed to this mechanical area, making it difficult to transport the heat exchange unit. At times, when the heat exchange unit was dropped, there was a risk that the mechanical area of the bottom plate would deform due to the weight of the compressor.

The purpose of this invention is to make it difficult for the mechanical area to which the compressor is fixed to deform when the heat exchange unit is dropped.

(d) Means for solving the problem In order to achieve this objective, the present invention attaches the leg pieces of the unit to the outer surface of the bottom plate of the machine area, and on the other hand, the part opposite to the leg pieces on the inner side of this bottom plate. is equipped with a refrigerant control valve, and a compressor is fixed between this control valve and a partition plate erected on the bottom plate.

(E) Function The mechanical area of the bottom plate where the compressor is mounted is reinforced with a partition plate and the leg pieces of the unit, and the control valve is held on the bottom plate reinforced by the leg pieces.

(F) Embodiment In the drawings, 1 is an outdoor heat exchange unit of a separate air conditioner. 2 is the bottom plate of this unit,
3 is a partition plate that divides the bottom plate into a mechanical area 4 and a heat exchange area 5, and the front edge 6 of this plate is connected to the bottom plate 2.
It is fixed to the rising edge 7 of. A wire guard 8, a heat exchanger 9, and a back panel 10 are provided upright at the rear of the bottom plate 2. 11 is the right tube plate of the heat exchanger 9, and the front piece 12 is attached to the rear edge 13 of the partition plate 3.
4 are fixed to the rising edges 7 of the bottom plate 2, respectively. In this way, the rising edges 7 near the center of the bottom plate 2 are connected by the partition plate 3 and the tube plate 11, thereby reinforcing the bottom plate 2.

A right leg piece 15 is spot-welded to the back surface of the mechanical area 4 of the bottom plate, and is fixed in the short direction of the bottom plate 2. 16 is a left leg piece that is spot welded to the back surface of the heat exchange area 5. A compressor 17 is fixed to a portion surrounded by the partition plate 3 and the right leg piece 15.
43 is an accumulator attached to the circumferential surface of the compressor 17 (not shown in FIG. 1). 18 is a discharge pipe extending upward from the top surface of the compressor 17;
It is bent into an inverted U shape, with the tip 19 facing downward. 20 is a four-way valve that controls the refrigerant discharged from the compressor 17, and a refrigerant pipe 21 bent downward into a U-shape is provided, and this pipe 21 is connected to the discharge pipe 18 of the compressor 17 described above. It is connected to the tip 19. Reference numeral 22 denotes a fixing member fitted to the bottom plate, which is made of a material with elasticity such as rubber, and is connected to the rising piece 2 of the machine area 4 of the bottom plate 2.
It is fitted into 3. Reference numeral 24 denotes a groove formed in this fixing member, into which a U-shaped refrigerant pipe 21 located below the four-way valve 20 is fitted. A right leg piece 15 is fixed to the back surface of the bottom plate on which the fixing member 22 is provided, and the right leg piece 15 reinforces the bottom plate in the portion where the fixing member is attached. In this way, even if vibrations from the compressor 17 are transmitted through the discharge pipe 18 and refrigerant pipe 21, this vibration is absorbed as much as possible by the fixed member 22, making it difficult for the vibration to be transmitted to the four-way valve 20. There is. 25 is a valve stand fixed to the right edge 26 of the bottom plate. Reference numeral 27 denotes a fan motor stand, one end 28 of which is fixed to a raised portion 29 of the bottom plate 2 and the other end 30 of which is locked to an upper part 31 of the heat exchanger 9. 32 is Juan, 33
The motor that drives this fan is the motor stand 27.
can be attached to.

34 is a front panel, a lower edge 35 is engaged with the front edge 7 of the bottom plate 2, and an upper edge 36 is screwed to the other end 30 of the fan motor stand 27. This front panel 34
A blowout grill 37 is attached to the. 38 is a left side panel that is applied from the left side of the unit. 39 is a suction port provided on this left side panel.

40 is a right side panel, which is applied from the right side of the unit 1. This right side panel 40
There is an opening 41 for taking out electrical components and a valve stand 25.
A notch 42 is formed to expose the.

In such a heat exchange unit 1, when the propeller fan 32 is rotated, outdoor air flows into the space of the wire guard 8 and the suction port 3 of the left side panel 38.
The refrigerant is sucked into the unit 1 through the refrigerant 9 and exchanges heat with the refrigerant flowing through the heat exchanger 9. The air heat-exchanged in this way is discharged from the blow-off grille 37.

(g) Effects of the invention As described above, the present invention provides a heat exchange unit in which the inside of the casing is divided into a heat exchange room and a mechanical room by a partition plate. The legs of the unit are fixed to the outer surface of the bottom plate of the machine room, and a refrigerant control valve is provided on the inner surface of the bottom plate in a portion facing the legs, and the refrigerant is connected between the control valve and the partition plate. The system is equipped with a compressor. Therefore, the part of the bottom plate where the compressor is installed is reinforced by the partition plate and the leg pieces, and even if the load of the compressor is applied to the bottom plate, it is possible to prevent the mechanical area of the bottom plate from deforming. . Furthermore, since the refrigerant control valve is fixed to the inner surface of the bottom plate reinforced with leg pieces, the bottom plate can receive vibrations from the compressor.
