The control device 81 includes a control board 81a, a control board 81b, a control board 81c, a control board 81d, and a control board 81e.

The control board 81a is an inverter control board on which a control circuit for inverter-controlling a compressor motor incorporated in the compressor 50 is mounted. As shown in FIG. 7, the control board 81a includes a circuit pattern 81ab made of copper and an inverter control element 81aa electrically connected to the circuit pattern 81ab by a lead wire 81L. The control board 81b is a power factor improving board on which a circuit for improving the power factor of the compressor motor built in the compressor 50 is mounted.

The control board 81c is a power supply board on which a power supply circuit for supplying power to the compressor 50, a noise filter, and the like are mounted. The control board 81d is a power supply board on which electrolytic capacitors 81da and the like are mounted. The control board 81e is a main control board on which a circuit for controlling the entire outdoor unit, such as a power supply circuit for supplying power to the fan motor that drives the blower fan 60, is mounted.

The control board 81b is attached to the back plate 80b through a board holder 84 that fixes the control board 81b, with the mounting surface on which various electrical components are mounted directed toward the inside of the electrical component box 80. As shown in FIG.

As shown in FIG. The control board 81d is mounted inside the lower box 80d. The control board 81e is attached to the front plate 80a with the mounting surface on which various electric components are mounted facing the front side of the outdoor unit 10. As shown in FIG. The attachment of the control board 81a to the board holder 83 will be described later.

FIG. 6 is an exploded perspective view schematically showing the electrical component box 80. As shown in FIG.
FIG. 6 shows the peripheral structure of the control board 81a arranged in the electric component box 80 of the outdoor unit 10. As shown in FIG. 6 does not show the front panel 80a, the rear panel 80b, etc. in order to explain the state inside the electrical component box 80. As shown in FIG.

As shown in FIG. 6, an inverter control element 81aa, which is a heat-generating component, is mounted on the control board 81a. The inverter control element 81aa generates heat due to an internal current flowing through an IPM (intelligent power module) including power transistors and the like when the outdoor unit 10 is in operation.

A heat sink 85 is provided in the electrical component box 80 to cool the inverter control element 81aa. As shown in FIGS. 6 and 7, the heat sink 85 includes a base 85a and a plurality of radiation fins 85b. The plurality of radiating fins 85b are all plate-shaped with the same thickness, and arranged in parallel with a predetermined interval in the vertical direction (the Z direction in FIG. 3). A plurality of radiation fins 85b are formed integrally with the base 85a. The inverter control element 81aa contacts the substrate 85a through the opening 83a. The surface of the substrate 85a with which the inverter control element 81aa contacts is the mounting surface of the substrate 85a.

Attachment of the left side plate 310 using the control board 81a and the board holder 83 of the heat sink 85 described above will be described with reference to FIG. The substrate holder 83 is made of a resin material and formed in a plate shape, and is formed so that the control substrate 81a is attached to one surface and the heat sink 85 is attached to the other surface. Further, the board holder 83 is provided with a rectangular opening 83a slightly larger than the inverter control element 81aa of the control board 81a.

First, the control board 81a is attached to one surface of the board holder 83 with screws. At this time, the mounting surface on which various electrical components (including the inverter control element 81aa) are mounted faces the substrate holder 83, and the inverter control element 81aa is mounted on the other surface of the substrate holder 83 through the opening 83a of the substrate holder 83. (the surface on which the heat sink 85 is attached).

Next, the heat sink 85 is attached to the other surface of the substrate holder 83 with screws. At this time, the heat sink 85 is attached so as to cover the opening 83a, and the inverter control element 81aa protruding from the opening 83a to the other surface of the substrate holder 83 contacts the mounting surface of the base 85a of the heat sink 85. FIG.

Then, the substrate holder 83 to which the control substrate 81a and the heat sink 85 are attached is screwed to the left side plate 310 from the side of the machine chamber 10e. At this time, the plurality of radiation fins 85b are exposed to the heat exchange chamber 10d side through the openings 31b provided in the left side plate 310, as shown in FIG.

Next, cooling of the electrical component box 80 will be described. A heat sink 85 cools the inverter control element 81aa of the control board 81a. Specifically, part of the outside air that has flowed into the heat exchange chamber 10d from the suction port A due to the rotation of the blower fan 60 flows to the heat radiation fins 85b of the heat sink 85, and the air flowing through the heat radiation fins 85b causes the base of the heat sink 85 to move. The heat generated by the inverter control element 81aa transmitted from 85a to the radiating fin 85b is radiated.

In addition, each control board other than the control board 81a stored in the electrical component box 80 is cooled by the rotation of the blower fan 60, which flows into the heat exchange chamber 10d from the suction port A, and cools the air above and below the opening 31b of the left side plate 310. It is cooled by the air that flows into the electrical component box 80 through the ventilation holes 31f provided in the rear panel 10g and the air that flows into the machine room 10e through the air intake holes 10h of the rear panel 10g.

As described above, when the electrical component box 80 is cooled by the outside air sucked from the suction port A, the moisture contained in the outside air taken in and the condensed water generated in the heat exchanger 40 are discharged from the heat exchange chamber 10d to the left side plate 310. There is a possibility that it may enter the inside of the electrical component box 80 through the opening 31b of the substrate holder 83 and the opening 83a of the substrate holder 83. A seal member 86, which is a waterproof material, is provided between the heat sink 85 and the substrate holder 83 in order to prevent the entry of moisture. The seal member 86 dams up moisture that has entered between the heat sink 85 and the substrate holder 83 from the heat exchange chamber 10d, thereby preventing moisture from entering the electrical component box 80 from the heat exchange chamber 10d. . The seal member 86 is made of, for example, an EPDM rubber material. A sealing member may also be provided between the left side plate 310 and the substrate holder 83 .

Next, features of the outdoor unit of the air conditioner according to this embodiment will be described. FIG. 7 is an exploded perspective view schematically showing the positional relationship among the control board 81a, the board holder 83, the heat sink 85 and the sealing member 86. As shown in FIG. In FIG. 7, the control board 81a, the board holder 83, and the heat sink 85 are shown separated from each other in order to show their arrangement relationship.

FIG. 8A shows a schematic cross section in the vertical direction of the inverter control element 81aa and the vicinity of the inverter control element 81aa. FIG. 8B shows a schematic cross-section in the vertical direction of the protrusion 831 provided on the substrate holder 83 and the vicinity of the protrusion 831 .

As described above, the control board 81a is attached to one of the board holders 83 with the mounting surface on which various electrical components (including the inverter control element 81aa) are mounted facing the heat exchange chamber 10d. At this time, the inverter control element 81aa is fixed in contact with the substrate 85a of the heat sink 85 through the opening 83a of the substrate holder 83 by the fixing member 81f.

The lead wire 81L of the inverter control element 81aa is soldered to the circuit pattern 81ab of the control board 81a, as shown in FIG. 8(a). The lead wire 81L is bent substantially at a right angle in the middle, and the bent tip 81t is soldered to the wiring pattern of the control board 81a. Thereby, the lead wire 81L and the wiring pattern provided on the control substrate 81a are electrically connected.

As shown in FIG. 7, the sealing member 86 is arranged between the base 85a of the heat sink 85 and the substrate holder 83, and arranged outside the opening 83a of the substrate holder 83 so as to surround the opening 83a.

The substrate holder 83 has an opening 83a for bringing the inverter control element 81aa into contact with the mounting surface of the heat sink 85, and two substrate holding portions 830 for suppressing warping of the control substrate 81a. The two substrate holding parts 830 each have a convex part 831 and a fixing member 832 and are arranged inside the portion surrounded by the sealing member 86 . In this embodiment, the substrate holder 83 is provided with two substrate holding portions 830 as described above. good. Also, three or more substrate holding portions 830 may be provided to suppress warping of the control substrate 81a.

The convex portion 831 is formed integrally with the substrate holder 83 when the substrate holder 83 is molded. The convex portion 831 faces the control board 81a.

The fixing member 832 is a fitting-type spacer that fixes between the protrusion 831 and the control board 81a. A fixing member 832 fixes between the protrusion 831 and the control board 81a. As shown in FIG. 8B, one end of the fixing member 832 is fitted into a through hole 831h provided in the projection 831, and the other end is fitted into another through hole 81h provided in the control board 81a. . As a result, warping of the control board 81a is suppressed, and the control board 81a and the board holder 83 are kept substantially parallel. Note that the fixing member 832 is made of an organic resin or an inorganic resin. Also, the fixing member 832 may be formed integrally with the convex portion 831 .

Here, for comparison with the present embodiment, FIG. 9 shows a case where a pedestal for fixing the fixing member 832 is provided separately from the substrate holder 83 . In the example shown in FIG. 9, a substrate holding portion 840 that suppresses warping of the control substrate 81a is composed of a pedestal 833 and a fixing member 832. As shown in FIG. The pedestal 833 is separate from the substrate holder 83, and an operation to attach the pedestal 833 to the substrate holder 83 is required. One end of the fixing member 832 is fitted into a through hole 833h provided in the base 833, and the other end is fitted into a through hole 81h provided in the control board 81a.

In FIG. 9, the pedestal 833 and the substrate holder 83 are configured as separate members. As a result, even if water enters between the substrate holder 83 and the heat sink 85, the water does not reach the control substrate 81a via the joint between the pedestal 833 and the fixing member 832. . However, since it is necessary to attach the pedestal 833 to the substrate holder 83, the component cost of the substrate holding portion 840 is high, and the number of manufacturing steps is increased.

On the other hand, in the present embodiment shown in FIGS. 7 and 8, since the convex portion 831 is formed by press drawing of the substrate holder 83, the step of attaching the convex portion 831 as a separate member is not required. Therefore, the substrate holding portion 830 does not require the work of attaching a separate member to the substrate holder 83, and the convex portion 831 is integrally formed with the substrate holder 83, so that the substrate holding portion 830 can be formed at a low cost.

However, the protrusion 831 is part of the substrate holder 83 . Therefore, when water enters between the substrate holder 83 and the heat sink 85, the water may reach the control substrate 81a via the joint between the fixing member 832 and the convex portion 831.

However, in this embodiment, the seal member 86 is arranged between the substrate holder 83 and the heat sink 85 so as to surround the inverter control element 81aa. This makes it difficult for water to enter between the substrate holder 83 and the heat sink 85 . A substrate holder 830 is arranged inside the portion surrounded by the seal member 86 . Therefore, the joint between the fixing member 832 and the convex portion 831 is configured such that water is less likely to reach it.

That is, according to the present embodiment, by arranging the substrate holding portion 830 that suppresses warping of the control substrate 81a as shown in FIG. 8B, the substrate holding portion 830 can be manufactured at low cost, and Although the substrate holding portion 830 is realized at low cost as described above, the presence of the seal member 86 surrounding the inverter control element 81aa and the substrate holding portion 830 prevents water from entering the control substrate 81a through the substrate holding portion 830. That is, water is reliably prevented from entering the machine room 10e.

Next, a second embodiment of the invention will be described mainly with reference to FIG. This embodiment differs from the first embodiment in that the control board 81a and the heat sink 85 are attached to the partition member (left side plate 310) via the board holder 83 described in the first embodiment. Instead, the control board 81a and the heat sink 85 are directly attached to the partition plate 311, which will be described later. The configuration of the outdoor unit 10 other than the above is the same as that of the first embodiment.

FIG. 10 is an exploded perspective view schematically showing the arrangement relationship among the control board 81a, the partition plate 311, the heat sink 85 and the sealing member 86. As shown in FIG. The control board 81a, the heat sink 85, and the seal member 86 are the same as those described with reference to FIG.

The partition plate 311 has a flat plate shape and is provided with an opening 311b for exposing the inverter control element 81aa to the heat exchange chamber 10d when the control board 81a is attached to the partition plate 311 .
Note that the partition plate 311 may be part of the left side plate 310 .

The heat sink 85 is attached to the surface of the partition plate 311 facing the heat exchange chamber 10d. The control board 81a is mounted so that the mounting surface of the partition plate 311 facing the interior of the electrical component box 80, on which the electrical components including the inverter control element 81aa are mounted, faces the heat exchange chamber 10d. At this time, the inverter control element 81aa is brought into contact with the base body 85a of the heat sink 85 through the opening 311b of the partition plate 311 and fixed.

A seal member 86 is arranged between the partition plate 311 and the heat sink 85 to prevent moisture from entering the electrical component box 80 from the heat exchange chamber 10 d through the opening 311 b of the partition plate 311 .

The partition plate 311 has two substrate holding portions 3110 that suppress warping of the control substrate 81a. The board holding part 3110 has a convex part 3111 formed integrally with the partition plate 311 and facing the control board 81a, and a fixing member 3112 fixing between the convex part 3111 and the control board 81a.

The sealing member 86 is arranged between the partition plate 311 and the heat sink 85 so as to surround the inverter control element 81aa. A substrate holding portion 3110 is arranged inside surrounded by the sealing member 86 .

According to this embodiment, the substrate holding portion 3110 can be manufactured at low cost, and the seal member 86 surrounding the inverter control element 81aa and the substrate holding portion 3110 can be manufactured at low cost as described above. , reliably prevents water from entering the control board 81a through the board holding portion 3110, that is, water from entering the machine chamber 10e.

Although the embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the above-described embodiments and can be modified in various ways. Each embodiment is not limited to an independent form, and can be combined as much as technically possible.
