- the control board 12 is configured with, for example, hardware such as a circuit device to enable its functions or software to be executed on an arithmetic device such as a microcomputer or CPU.
- the electric power board 11 is assembled with a rear face side contacting the partition plate 8, which partitions between the ventilation chamber 4 and the electric component chamber 3.
- the control board 12 is arranged to be separated by a space S from the electric power board 11.

- the external air is allowed to pass into the casing 14 through the air inlet (the louver 16) formed at the casing 14.
- a heat sink 6 for cooling the electric power board 11 accommodated in the electric component chamber 3 is accommodated.
- Fig. 4 is a perspective view schematically illustrating a heat sink included in the outdoor unit for the air-conditioning apparatus, in one embodiment of the present invention.
- the heat sink 6 is a metal plate made of aluminum, copper, or the like, with an excellent heat dissipation, and includes a base plate in a flat plate shape (not illustrated) and a plurality of standing cooling fins 61, which are spaced apart from each other, on the top face of base plate.
- the heat sink 6 is secured on the inside of a frame body 60 made of, for example, metal such as aluminum or copper, or resin.
- the frame body 60 including the heat sink 6 therein is attached to the partition plate 8 for partitioning between the electric component chamber 3 and the ventilation chamber 4. At a position facing the heat sink 6 through the partition plate 8, the electric power board 11 in the electric component chamber 3 is disposed.
- a heat sink inlet 6a serving as an opening for sucking into the heat sink 6 the external air that has flown into the ventilation chamber 4, is formed at a position facing the louver 16.
- a heat sink outlet 6b serving as an opening for discharging the air that has flown into the heat sink 6, is formed on a side face facing the heat exchanger chamber 5. That is, in the heat sink 6, the external air that has been sucked into the ventilation chamber 4 is taken from the louver 16 arranged on the side face of the casing 14 into the heat sink 6 through the heat sink inlet 6a, and is discharged from the heat sink 6 through heat sink outlet 6b.
- the heat sink 6 is configured such that the heat sink inlet 6a is arranged to face the louver 16. This configuration facilitates the external air that has flown from the louver 16 to be taken into the heat sink 6, and enhances a cooling effect.
- the cooling fins 61 of the heat sink 6, as illustrated in Fig. 4 are horizontally arranged to be spaced apart from each other. This configuration minimizes resistance to the wind that has entered, and enhances the cooling effect, while ensuring the wind amount sufficiently.
- the cooling fins 61 are not limited to the configuration in which the cooling fins 61 are horizontally arranged, and may have another configuration with another arrangement.

- the ventilation passage 80 is formed as a rectangular cutout at a corner of an upper end of the partition plate 8. The reason why the ventilation passage 80 is formed at the corner of the upper end of the partition plate 8 is to prevent water droplets generated in the casing 14 from entering the electric component chamber 3. The water droplets drip downward because of gravity effects, and are not capable of passing over the ventilation passage 80.
- the ventilation passage 80 may be formed near the upper end of the partition plate 8, but is not limited to being formed near the upper end, as illustrated. Additionally, the ventilation passage 80 is desirably formed near the upper end of the partition plate 8, but may be provided in a lower area of the partition plate 8. Furthermore, a plurality of ventilation passages 80 may be configured in parallel with each other.
- the ventilation passage 80 is not limited to a rectangular cutout, and may be, for example, a circular one.
- the ventilation passage 80 can allow communication between the electric component chamber 3 and the ventilation chamber 4 to allow the air in the ventilation chamber 4 to flow into the electric component chamber 3.
- the position, shape, and size of the ventilation passage 80 may be changed in consideration of a carried-out situation, as appropriate.
- the heat exchanger chamber 5 is partitioned by the partition plate 10 from the machine chamber 2, the ventilation chamber 4, and the electric component chamber 3.

- a duct 13 for allowing communication between the heat exchanger chamber 5 and the ventilation chamber 4, and for allowing communication between the heat exchanger chamber 5 and the electric component chamber 3, is provided.
- the outdoor heat exchanger 7, as illustrated in Fig. 3 has for example, a letter L shape in plan view, and is provided along a left side face part in the front side face panel and along the rear face panel.
- the outdoor fan 15 serves as an air-sending unit configured with, for example, a propeller fan, and generates air circulation for heat exchange in an effective manner.
- the outdoor fan 15 has a function of sucking the external air into the outdoor unit 1 from the rear face side of the outdoor unit 1, and blowing out the external air that has been sucked into the outdoor unit 1 towards the front face side of the outdoor unit 1.
- the outdoor fan motor serves as a driving unit configured to drive the outdoor fan 15, and is attached to a support plate provided in the heat exchanger chamber 5 using securing means, for example, a screw.
- Fig. 5 is a perspective diagram schematically illustrating a duct included in the outdoor unit for the air-conditioning apparatus, in one embodiment of the present invention.
- the duct 13 is illustrated when viewed from the rear face side.
- the duct 13 is provided for smoothly sucking wind from the ventilation chamber 4 and the electric component chamber 3 into the heat exchanger chamber 5.
- the duct 13, as illustrated in Figs. 1 to 3 is attached to the partition plate 10, and extends over the partition plate 8, which partitions between the ventilation chamber 4 and the electric component chamber 3.
- a first duct inlet 13a in communication with the ventilation chamber 4 and a second duct inlet 13b in communication with the electric component chamber 3 are formed on the rear face of the duct 13.
- the duct 13 includes an opening face facing downward on the heat exchanger chamber 5 side, as a duct outlet 13c for discharging the air that has flown into the duct 13.
- the first duct inlet 13a in communication with the ventilation chamber 4 is in communication with the heat sink outlet 6b of the heat sink 6 accommodated in the ventilation chamber 4.
- the air that has been discharged from the heat sink outlet 6b flows from the first duct inlet 13a into the duct 13, and flows out of the duct outlet 13c into the heat exchanger chamber 5.
- the second duct inlet 13b in communication with the electric component chamber 3 is arranged at a position of the gap defined between the electric power board 11 and the control board 12.
- the partition plate 10 has an opening in communication with the second duct inlet 13b with the opening formed in the partition plate 10 at a position of the gap. The air that has flown into the electric component chamber 3, cools the electric component chamber 3, then flows into the duct 13 from the second duct inlet 13b, and flows out of the duct outlet 13c into the heat exchanger chamber 5.
- the air that flows into the heat sink 6 flows from the heat sink inlet 6a into a frame body 60. After passing through the plurality of cooling fins 61, the air flows out of the heat sink outlet 6b. The air flows into the heat sink 6, and therefore cools the electric power board 11 accommodated in the electric component chamber 3.
- the air that has flown out of the heat sink outlet 6b flows from the first duct inlet 13a in communication with the heat sink outlet 6b into the duct 13. Then, the air changes its direction to flow downward in a vertical direction, and flows out of the duct outlet 13c into the heat exchanger chamber 5. After the air that has flown into the heat exchanger chamber 5 is subject to heat exchange with refrigerant through the outdoor heat exchanger 7, the air blows out of the outlet of the front side face panel by an outdoor fan 15.
- the air that has flown into the electric component chamber 3 through the ventilation passage 80 formed at the partition plate 8 passes through the gap between the control board 12 and the electric power board 11, and flows into the duct 13 from the second duct inlet 13b in communication with the heat exchanger chamber 5. Then, the air changes its direction to flow downward in the vertical direction, and flows out of the duct outlet 13c into the heat exchanger chamber 5. Then, the air that has flown into the heat exchanger chamber 5 is subject to heat exchange with refrigerant through the outdoor heat exchanger 7. After the heat exchange is carried out between the refrigerant and the air, the air is blown out of the outlet of the front side face panel by the outdoor fan 15.
- the ventilation passage 80 for allowing communication between the ventilation chamber 4 and the electric component chamber 3 is formed at the partition plate 8, which partitions between the ventilation chamber 4 and the electric component chamber 3.
- the external air that has sucked by the ventilation chamber 4 is supplied through the ventilation passage 80 to the electric component chamber 3.
- the air that has flown into the electric component chamber 3 is enabled to sufficiently cool the electrical components, such as the control board 12, separated from the heat sink 6 and having a high necessity to be cooled, so that the temperature of the entire electric component chamber 3 is reduced, and a degradation of the electrical components is prevented.
- the heat sink 6 is disposed through the partition plate 8 to be adjacent to the electric power board 11 disposed in the electric component chamber 3.
- the control board 12 is spaced apart from the electric power board 11 by the space S.
- the rear face side of the electric power board 11 is directly cooled by heat sink 6, and the front face side of the electric power board 11 facing the control board 12 is cooled by the air that has flown into the gap between the electric power board 11 and the control board 12. This configuration enhances the cooling effect of cooling the electric power board 11, which generates heat the most.
- the ventilation chamber 4 and the electric component chamber 3 are partitioned from the machine chamber 2 by the partition plate 9.
- the external air that has flown into the ventilation chamber 4 is not allowed to enter the machine chamber 2 having a low necessity to be cooled, but a large amount of wind is allowed to enter the electric component chamber 3 having a high necessity to be cooled.
- the cooling effect is enhanced.
- any sound that is generated in the machine chamber 2 is insulated by the partition plates 9 and 10, and is less likely to be transmitted to the outside from the louver 16. Hence, a noise prevention effect also works.
- the partition plate 8 partitions between the electric component chamber 3 and the ventilation chamber 4, and therefore it becomes difficult for water droplets such as rain that has flown from the louver 16 hardly enter the electric component chamber 3. This configuration prevents corrosion of the electric components disposed in the electric component chamber 3, and maintains the quality.
- the ventilation passage 80 is arranged near the upper part of the partition plate 8. Hence, even in a case where water droplets are generated in the inside of the outdoor unit 1, the water droplets that drip downward because of gravity effects do not pass over the ventilation passage 80. Thus, in the outdoor unit 1, air is allowed to flow into the electric component chamber 3 from the ventilation chamber 4 to cool the electric power board 11 and the control board 12. In addition, liquid is prevented from entering the electric component chamber 3 in an effective manner.
- the duct 13 for allowing communication between the heat exchanger chamber 5 and the ventilation chamber 4, and for allowing communication between the heat exchanger chamber 5 and the electric component chamber 3 is provided with the opening face facing downward, on the heat exchanger chamber 5 side.
- the rain that has entered from the outlet of the heat exchanger chamber 5 is prevented from entering the electric component chamber 3 through the duct 13.
- the electric components that are accommodated in the electric component chamber 3 are prevented from corroding, and the quality is maintained.
- an outdoor fan 15 in a case where an outdoor fan 15 is arranged below the duct 13, an effect of readily sucking wind due to the negative pressure of the outdoor fan 15 into the inside works.
- the heat sink 6 is arranged in the frame body 60 having an opening (the heat sink inlet 6a) at a position facing the inlet formed in the casing 14. Hence, the external air that has been sucked from the louver 16 is readily supplied into the inside through the opening, and the cooling effect is enhanced.
- the cooling fins 61 of the heat sink 6 are arranged horizontally. This configuration minimizes resistance to the wind that has entered the frame body 60, secures a sufficient amount of wind, and enhances the cooling effect.
- the louver 16 including inflow openings facing downward is provided at the inlet of the casing 14. This configuration makes it difficult for rain to enter the ventilation chamber 4 even at the time of a storm, and also prevents the rain from entering the electric component chamber 3. Accordingly, in the outdoor unit 1, the electric parts are prevented from corroding caused by entering of the rain, and the quality is maintained.
- the present invention has been described based on the embodiments, but the present invention is not limited to the configurations in the above-described embodiments.
- the duct 13 may be provided individually for the ventilation chamber 4 and the electric component chamber 3.
