[Detailed description of the invention] (a) Industrial application field The present invention relates to a heat exchange unit in which the inside of the housing is divided into a machine room and a heat exchange room by a partition plate.

(b) Prior Art Conventionally, as an example of the structure of a heat exchange unit in which the inside of the housing is divided into a machine room and a heat exchange room by a partition plate, the one shown in Japanese Utility Model Publication No. 47-22786 has been disclosed. ing.

According to this content, a notch is provided in the partition plate,
A refrigerant pipe disposed across the machine room and the heat exchange room is passed through this notch, and a gap between the notch and the refrigerant pipe is closed with a shielding member. In this way, the inside of the housing is divided into a machine room and a heat exchange room by a partition plate.

(c) Problems to be solved by the invention In such a heat exchange unit, a fan and an electric motor for driving the fan are disposed in the heat exchange chamber. The lead wires of this motor passed through the partition plate from a place other than the notch and were led into the machine room. Since the refrigerant piping and lead wires were led into the machine room from different locations within the partition plate, there was a risk that the assembly work of the unit would become complicated.

The object of the present invention is to easily fix the lead wire passing through the partition plate, and to reduce the risk of the lead wire being bent and damaged.

(d) Means for solving the problem In order to achieve this objective, the present invention includes a shielding member that closes the gap between the refrigerant pipe passed through the notch of the partition plate and this notch, from which the electric motor of the fan is connected. This allows the lead wires extending to the machine room to pass through.

(E) Function The refrigerant pipes and lead wires in the heat exchange unit are arranged to extend from the heat exchange room to the machine room through one notch in the partition plate.

(F) Embodiment In FIG. 1, 1 is an outdoor heat exchange unit of a separate air conditioner, and the casing of this unit includes a bottom plate 2, a wire guard 3, a back panel 4,

It is erected on the left side of the bottom plate 2.

Reference numeral 16 denotes a fan; 17 a motor 18 for driving the fan; the upper end 19 of which is engaged with the upper edge 20 of the main heat exchanger, and the lower end 21 of which is fixed to the bottom plate 2; Reference numeral 22 denotes a flat plate-shaped auxiliary heat exchanger, and a part of the bottom surface thereof is placed on the horizontal surface 23 of the mounting base 18 . A lead wire 24 is led out from this electric motor 17, and this lead wire is led upward along a vertical surface 25 of the mounting base 18 and extends into the machine room 10 through the notch 11.

Reference numeral 26 denotes a right tube plate of the auxiliary heat exchanger 22, which is formed into a substantially L-shape, and a horizontal piece 27 is fixed to the upper surface 28 of the partition plate 8. Reference numeral 29 denotes a left tube plate of the auxiliary heat exchanger 22, which is formed in a U-shape and has an auxiliary metal fitting 30 fixed thereto. 31 is a suction grill formed on the left side panel 6, 32 is an outlet grill formed on the front surface of the cabinet 5, and 33 is a cabinet 5.
It is a suction grill formed on the top surface of the

34 is a mounting plate fixed to the right rising edge 35 of the bottom plate 2, and a valve is disposed on this mounting plate. Reference numeral 36 denotes a notch formed below the right side panel 7, through which the bulb is exposed. 3
7 is an opening for taking out lead wires of electrical components.

Compressors 38 and 39 are installed upright on the right side of the bottom plate 2, and these first and second compressors 38 and 39, the main heat exchanger 15, and the auxiliary heat exchanger 22 are connected as shown by the dashed line arrow. Ru.

That is, 40 is a discharge pipe of the first compressor 38,
Extending above the compressor 38, this discharge pipe 40 is connected via the notch 11 of the partition plate 8 to an inlet pipe 41 located on the right tube plate 26 of the auxiliary heat exchanger 22.

Reference numeral 42 denotes an outlet side pipe of the auxiliary heat exchanger 22, which is located on the right tube plate 26 and is connected to the first pipe 43 at the upper part of the main heat exchanger 15 via the notch 11.

A discharge pipe 44 of the second compressor 39 extends above the compressor, and the discharge pipe 44 is connected to a second pipe 45 above the main heat exchanger 15.
In this way, the refrigerant discharged from the first compressor 38 flows from the auxiliary heat exchanger 22 to the main heat exchanger 15, and the refrigerant discharged from the second compressor 39 flows to the main heat exchanger 15.

In FIG. 2, reference numeral 46 denotes a shielding member disposed in the notch 11, which is made of foamed rubber and has elasticity. 47 and 48 are engaging pieces that alternately protrude on both sides of the shielding member, and both engaging pieces 47,
The side portion 50 of the notch 11 of the partition plate 8 fits into the gap 49 of the partition plate 8 . 51 is an engagement groove formed on the lower side of the shielding member, into which the bent piece 12 of the partition plate 8 is fitted. Reference numerals 52 and 53 indicate through holes through which the refrigerant pipes pass, which are vertically arranged and provided with downward cuts 54 and 55, respectively. The inlet pipe 41 of the auxiliary heat exchanger 22 is inserted into the upper through hole 52 by widening the cuts 54 and 55, and the outlet pipe 4 of the auxiliary heat exchanger 22 is inserted into the lower through hole 53.
2 are arranged respectively. Reference numeral 56 denotes an insertion hole through which the lead wire 24 of the electric motor 18 is passed, and this insertion hole 56 is formed with a collar 57 extending toward the heat exchange chamber side and the machine room side. Reference numeral 58 denotes a cut formed in the upper part of the collar, and the lead wire 24 is positioned in the insertion hole 56 by widening the cut 58. In FIG. 3, reference numeral 59 denotes a wire bundle band wrapped around the collar 57 on the side of the heat exchange chamber, which prevents the lead wire 24 from coming out from the insertion hole 56. The height dimension a of this shielding member 46 is somewhat larger than the height dimension b of the notch 11, and when the shielding member 46 is fitted into the notch 11 as shown by the solid line arrow, the upper surface of this member 46 and The partition plate 8 is flush with the gasket 14.

When assembling such a heat exchange unit 1,
The lower cuts 54 and 55 of the shielding member 46 are widened and the respective pipes 41 and 4 are inserted into the respective through holes 52 and 53.
2, and then, with the piping attached, the shielding member 46 is fitted into the notch 11 and the engagement groove 51 is inserted into the bent piece 12.

Next, widen the upper notch 58 and
4 in the insertion hole 56, the collar 57 is tied with a binding band 59, and the lead wire 24 is inserted into the shielding member 46.
Fixed to. After the shielding member 46 is attached to the partition plate 8 in this way, when the partition plate is covered with the cabinet 5, the inner wall of the cabinet 5 is attached to the gasket 1.
4 and the upper surface of the shielding member 46, the inside of the unit 1 is reliably divided into a machine room 9 and a heat exchange room 10.

Further, since the inlet pipe 41 through which a high-temperature refrigerant flows is arranged in the lower part of the shielding member 46, and the outlet pipe 42 through which a relatively low-temperature refrigerant flows in the center, the lead wire 24 can pass through the inlet pipe 41. This makes it less susceptible to the effects of heat from flowing high-temperature refrigerant.

(g) Effects of the invention As detailed above, the invention provides a notch in the partition plate that divides the inside of the housing into the machine room and the heat exchange room.
A shielding member is attached to this notch, and the refrigerant pipe and the lead wire are passed through this shielding member. Therefore, the structure of the partition plate can be simplified compared to conventional partition plates that have separate cutouts for passing the refrigerant pipes and lead wires, and this makes the structure of the heat exchange unit easier. Assembly work can be done easily. Furthermore, the risk of the lead wire being bent and damaged by the shielding member can be reduced.
