  Conventionally, there is a power conditioner device 80 having a rear intake / bottom exhaust structure as shown in FIG. 6 as one of the power conditioner devices adopting the outside air introduction method. FIG. 6 is a perspective view of the power conditioner device 80 according to the comparative example as viewed from the back side.

  A door 82 is provided on the front surface of the housing 81, and fixing brackets 83 for attaching the power conditioner device 80 to a mounting surface such as a wall are provided at four corners of the back surface 84 of the housing 81. In addition, an air inlet 85 is provided on the back surface 84 of the housing 81, and a cover box portion 86 is attached so as to cover the air inlet 85. Further, air inlets 87 for taking in outside air are provided on the inclined surfaces on the left and right sides of the cover box portion 86. Air taken into the cover box 86 from the air inlet 87 passes through the air inlet 85 on the back surface 84 and is taken into the housing 81. Further, the air that has cooled the device in the casing 81 is exhausted from an exhaust port provided on the bottom surface of the casing 81. In this way, the power conditioner device 80 employs a rear intake / bottom exhaust structure in order to cool the inside of the device.

  However, the power conditioner device is often attached to the wall of a house or the inner surface of a storage box, and the back surface of the housing faces an attachment surface such as a wall in use. For this reason, when performing maintenance such as filter replacement of the intake port 85 due to clogging or the like, it is necessary to remove the power conditioner device from the mounting surface, which increases the maintenance time.

  In addition, since the intake port for taking outside air into the housing 81 is only one place on the rear intake port 85, the amount of the inflow air is greatly reduced when the filter of the intake port 85 is clogged. In that case, since the temperature inside the apparatus rapidly increases, the power conditioner apparatus performs a reduction operation that reduces the output to 30 to 50% of the maximum allowable output. As a result, there is a problem that the power generation amount is greatly reduced.

  Furthermore, high waterproof performance is also required for power conditioner devices installed outdoors.

  Therefore, an object of the present invention is to provide a power conditioner device capable of reducing the maintenance time of the intake port and maintaining the power generation amount as high as possible. It is also an object of the present invention to improve the waterproof performance of the power conditioner device.

(Solar power system)
The structure of the photovoltaic power generation system including the power conditioner device will be described with reference to FIG. As shown in FIG. 5, the photovoltaic power generation system 500 includes a power conditioner device 1, a solar battery 200 that supplies direct-current power (for example, DC 200 to 500 V) to the power conditioner device 1, and a transformer device 300. . The power conditioner device 1 converts the DC voltage supplied from the solar cell 200 into a three-phase AC (for example, 200 V) and outputs the converted voltage. This AC power is transformed to a high voltage (for example, 6600 V) by the transformer 300 connected to the output terminal of the power conditioner device 1 and supplied to the commercial distribution network.

(Power conditioner device)
Next, the power conditioner device 1 according to the embodiment of the present invention will be described in detail. FIG. 1: has shown the perspective view seen from the back side of the power conditioner apparatus 1 which concerns on embodiment of this invention.

  As shown in FIG. 1, the power conditioner device 1 is a so-called wall-mounted power conditioner device, and is attached to a mounting surface such as a wall by fixing brackets 4 provided at four corners of the back surface 5 of the housing 2. . In addition, on the front surface of the housing 2, there are access to electrical equipment (for example, a DC / AC inverter that converts direct current power into alternating current power) and intake / exhaust air filters installed in the housing 2. A door 3 is provided.

  As shown in FIG. 1, the power conditioner device 1 has a so-called side surface intake / bottom surface exhaust structure that sucks air from the side surface of the housing 2 and exhausts air from the bottom surface.

  Next, the internal structure of the power conditioner device 1 will be described with reference to FIGS. FIG. 2 shows a cross section of the casing 2 of the power conditioner device 1 and an upper surface of devices installed in the casing 2. FIG. 2 does not show the inlet filter. FIG. 3 shows a cross-sectional perspective view near the air inlet 8, and FIG. 4 shows a cross-sectional perspective view near the air inlet 9.

  The housing 2 has a substantially rectangular parallelepiped shape, and includes a side surface 6 provided with an intake port 8, a side surface 7 provided with an intake port 9, a lower surface 10 provided with an exhaust port 11, and an upper surface 23.

  As shown in FIG. 2, a power conversion unit 12 is installed in the housing 2 near the intake port 8 (left side in FIG. 2). The power converter 12 includes a DC / AC inverter that converts DC power into AC power. The power converter 12 is provided with a power MOSFET 12a, a transformer 12b, and the like. The power MOSFET 12a is screwed to the side surface of the heat sink 12c in order to increase the cooling efficiency.

  In addition, an interface unit 13 for inputting DC power and outputting AC power is installed in the housing 2 near the inlet 9 (on the right side in FIG. 2). Since the interface unit 13 does not include a part having a large heat generation amount, the interface unit 13 is sufficiently cooled only by lightly flowing cooling air.

  On the other hand, since the power conversion unit 12 includes a heat source such as a power MOSFET 12a and a transformer 12b, the amount of heat generated is much larger than that of the interface unit 13. Therefore, in order to suppress the temperature rise inside the apparatus, it is necessary to actively cool the power conversion unit 12 using a fan.

  The partition plate 17 with an opening is a partition plate provided with an opening, and is disposed between the interface unit 13 and a cover unit 30 (described later) with a louver of the intake port 9. The air that has flowed into the housing 2 through the internal air inlet 31 of the cover unit 30 with the louver flows into the space where the interface unit 13 is installed through the opening of the partition plate 17 with the opening. The air that has flowed in is sucked into the fan unit 24 and flows obliquely upward to cool the interface unit 13.

  The intake port 9 is preferably provided below the side surface 7. Thereby, the interface part 13 is located between the air inlet 9 and the fan part 24, and the interface part 13 can be efficiently cooled by the air sucked from the air inlet 9.

  The fan unit 24 is provided between the upper surface 23 of the housing 2 and the power conversion unit 12. The fan unit 24 sucks the upper air and blows it toward the lower power conversion unit 12. The air blown from the fan unit 24 cools the power conversion unit 12 and then is discharged to the outside from the exhaust port 11 provided on the lower surface 10 of the housing 2.

  The fan part 24 is sucked from the air inlet 8, rises along the flow path C, passes through an opening 11 a (described later) of the cover part 11, and air sucked from the air inlet 9 and passes through the interface part 13. Both are sucked and blown to the lower power converter 12. Therefore, even if one of the intake ports 8 and 9 reduces the amount of air inflow due to filter clogging or the like, the power conversion unit 12 can be cooled by the air taken in by the other intake port.

  The exhaust port 11 is provided below the power conversion unit 12 and is configured to discharge only the air that has passed through the power conversion unit 12 to the outside of the housing 2. Specifically, a cylindrical duct portion 15 connected to a partition plate (partition plates 14 and 25 described later) is attached to the exhaust port 11. For this reason, for example, the air that has passed through the interface unit 13 does not pass through the power conversion unit 12 and is not discharged outside the housing 2. 12 can be used for cooling.

  Further, a filter 16 is provided so as to cover the exhaust port 11 from the inside of the housing 2.

  The partition plate 25 is provided between the power conversion unit 12 and the interface unit 13. By providing the partition plate 25, the flow path of the cooling air in the housing 2 can be controlled. That is, air that has been taken in from the air inlet 9 and has cooled the interface unit 13 flows into the power conversion unit 12 without passing through the fan unit 24, and conversely, air that cools the power conversion unit 12 flows into the interface unit 13. This can be prevented.

  Further, the partition plate 14 is provided between a cover unit 20 (described later) and the power conversion unit 12. The partition plate 14 can prevent the air that has flowed into the housing 2 through the opening 21 of the cover portion 20 from flowing into the space where the power conversion portion 12 is installed without passing through the fan portion 24.

  The partition plates 14 and 25 may be provided as side plates of the power conversion unit 12, or may be provided as a part of the housing 2 so as to protrude from the inner back surface of the housing 2.

  Further, the intake port 8 is not limited to the lower side of the side surface 6, and may be provided at the center or upper side of the side surface 6.

  In FIG. 2, the intake port 8 is provided on the left side and the intake port 9 is provided on the right side. That is, the intake port 9 may be provided on the left side, and the intake port 8 may be provided on the right side. In this case, the interface unit 13 is disposed on the left side of the housing 2, and the power conversion unit 12 is disposed on the right side of the housing 2.

  As described above, in the present embodiment, the intake ports 8 and 9 are provided on the side surfaces 6 and 7 of the housing 2, respectively. For this reason, it is not necessary to remove the power conditioner device 1 from the mounting surface during maintenance such as exchanging the filter due to clogging. Therefore, maintenance man-hours can be reduced and maintenance time can be reduced.

  Further, in the present embodiment, the air sucked from the air inlet 9 is sucked into the fan unit 24 to cool the interface unit 13 disposed in the middle of the flow path and having a relatively small amount of heat, and then the power conversion unit. 12 is used for cooling. As described above, in order to cool the power converter 12 having a large calorific value, not only the air sucked from the intake port 8 but also the air sucked from the intake port 9 and used for cooling the interface unit 13 is used. According to the embodiment, even when the intake amount by one of the intake ports 8 and 9 is reduced due to clogging of the filter or the like, the power conversion unit 12 that occupies most of the heat generation amount is supplied with the air sucked from the other intake port. Can be used to cool. For this reason, it can prevent that the internal temperature of a power conditioner apparatus raises remarkably, and can suppress generation | occurrence | production of the decelerating operation | movement in which electric power generation amount falls significantly. As a result, according to the present embodiment, the power generation amount can be maintained at a high level.

  Furthermore, in the power conditioner device of this embodiment, the waterproof performance is improved by applying various devices to the intake ports 8 and 9, and the waterproof grade JIS IPX4 is achieved.

  Hereinafter, the configuration near the intake port 8 and the intake port 9 will be described in detail. As shown in FIGS. 1 and 2, each of the intake ports 8 and 9 is composed of a plurality of small intake ports 18, 18... And 28, 28. That is, the intake port 8 is composed of a plurality of small intake ports 18, and the intake port 9 is composed of a plurality of small intake ports 28. In order to improve the waterproof performance of the power conditioner device, louvers 19 and 29 are provided at each small intake port. As shown in FIGS. 2 and 3, the louver 19 is provided so as to protrude from the upper edge of the small intake port 18 toward the outside of the housing 2 and to cover the small intake port 18. Similarly, as shown in FIGS. 2 and 4, the louver 29 is provided so as to protrude from the upper edge of the small intake port 28 toward the outside of the housing 2 and to cover the small intake port 28. By providing the louvers 19 and 29, it is possible to prevent external water droplets from directly entering the inside of the power conditioner device.

  As shown in FIG. 3, a filter 38 is provided inside the intake port 8. Similarly, as shown in FIG. 4, a filter 39 is provided inside the intake port 9.

  The cover portion 20 is provided so as to cover the air inlet 8 from the inside of the housing 2, and forms a flow path C for guiding the air sucked from the air inlet 8 to the fan portion 24 together with the side surface 6. In addition, an opening 21 is provided in the upper portion of the cover portion 20 in order to allow air that has been sucked from the air inlet 8 and passed through the flow path C to pass through the inside of the housing 2.

  By providing the cover unit 20, it is possible to prevent water droplets outside the apparatus from entering the installation space of the power conversion unit 12 and the like, and the air sucked from the intake port 8 can be efficiently passed to the fan unit 24 through the flow path C. Can lead.

  In the channel C, water drop plates 26 and 27 are provided. The water drop dropping plate 26 protrudes from the cover portion 20 toward the side surface 6, and the water drop dropping plate 27 protrudes from the side surface 6 toward the cover portion 20. Thereby, the water droplet which entered from the inlet port 8 can be prevented from proceeding to the upper side of the flow path C, and the waterproof performance of the power conditioner device can be improved. Only one of the water drop dropping plates 26 and 27 may be provided.

  The cover portion 20 has a lower surface 22 that is connected to the side surface 6 at the lower end of the intake port 8 (the small intake port 18 arranged at the lowest side) and is inclined in the direction of the side surface 6. As a result, water droplets that have entered the interior via the intake port 8 fall along the lower surface 22 and are discharged from the intake port 8 to the outside. As a result, water droplets can be prevented from accumulating in the space defined by the side surface 6 and the cover portion 20, and the waterproof performance of the power conditioner device can be improved.

  Next, a detailed configuration of the intake port 9 will be described with reference to FIGS. 2 and 4.
