[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switchgear heat radiating device for shutting off solar radiation and radiating heat in the switchgear of a switchgear such as an outdoor switchboard.

[0002]

2. Description of the Related Art A conventional switchgear has the structure shown in FIGS. In the figure, 1 is the ground, 2 is a base base arranged in a square on the ground 1,
3 is a switch gear installed on the base 2, 4 is a side decorative panel directly attached to the side surface 5 of the switch gear 3, 6
Is a ceiling plate, 7 is an upper plate, 8 is a cover of an edge of the upper plate 7, 9 is a viewing window, and 10 is an operation door.

Further, as shown in FIG. 3B, a decorative plate 4 is attached to a side surface 5 of a switch gear 3 via an air layer 11, and as shown in FIG. In some cases, a heat insulating material 12 is inserted between the heat insulating material and the heat insulating material 4.

[0004]

[Problems to be Solved by the Invention] In general, when the temperature inside the panel of the switchgear 3 becomes the highest, the operating state in which the heat generation of the equipment inside the panel becomes the maximum and the midsummer afternoon (the afternoon) when the temperature is the highest in the year At about 2 o'clock), the angle of the sun is slightly west, and the angle is shallow if the veneer 4 is southwest, but if the veneer is facing west, the sun's sunlight hits the veneer 4 properly. Is absorbed into the board.

[0005] In the case of Fig. 3A, there is a problem that the heat is directly conducted into the board by heat conduction of the steel material constituting the decorative board 4, and the temperature inside the board becomes high. In the case of FIG. 3B, the air layer 11 has a somewhat heat insulating effect, but still conducts by convection.

Next, in the case of FIG. 3C, the heat insulating material 12 provides much more heat insulation than that of FIG. 3B. However, there is a problem in that the heat absorbed by the upper plate 7 and the heat generated in the panel are not radiated by the heat insulating material 12, and the heat insulating material 12 functions as a heat insulating material and excessively raises the temperature in the panel. SUMMARY OF THE INVENTION An object of the present invention is to provide a switchgear heat radiating device that can effectively block the sun's solar radiation and radiate the heat in the panel, keeping the above points in mind.

[0007]

In order to solve the above-mentioned problems, a switchgear heat radiating device of the present invention has a square base on a ground, a base installed on the base, and a bottom closed. A switch pit, a wiring pit formed in the ground and communicating with the base, a ventilation port penetrating through the base and communicating from the inside to the outside, and disposed on a side surface of the switch gear via an air layer. A decorative plate, an extended portion extending from a lower end of the decorative plate, forming a passage between the ventilation port and the air layer, and intercepting between the passage and the ground, and provided above the air layer. A cover for preventing rainwater from entering the air layer; and an exhaust port formed between the cover and an outer surface of the decorative board for discharging air in the air layer downward.

[0008]

The switchgear heat radiating device of the present invention having the above-described structure includes a wiring pit, a base base, a ventilation opening of the base base, a passage communicating with an air layer between the side of the switchgear and the decorative plate, Since the ventilation path of the air layer and the exhaust port of the cover is formed, when the decorative panel receives heat due to the sunshine, the air in the air layer is heated and the specific gravity becomes small, and the warmed air is used as the exhaust port of the cover. From the pit for drainage and the cold air surrounded by the base base below the switchgear, enter the air layer through the ventilation port,
The solar heat discharged from the exhaust port and absorbed by the decorative board is not transmitted to the switchgear. Further, the heat generated in the panel is also cooled and radiated by the air discharged from the bottom and side surfaces of the switchgear.

[0009]

An embodiment will be described with reference to FIG.
2, the same reference numerals as those in FIGS. 2 and 3 denote the same or corresponding components. Reference numeral 13 denotes a wiring pit formed on the ground 1 and communicated with the inside of the base 2, 14 is a ventilation hole penetrated through the base 2 and communicated from the inside to the outside, and 15 is an extension provided at the lower end of the decorative panel 4. A passage 16 between the air layer 11 and the ventilation port 14 formed between the side face 5 of the switchgear 3 whose bottom is closed and the decorative board 4.
6 and the ground 1 are shut off. Reference numeral 17 denotes a cover provided above the air layer 11 to prevent rainwater from flowing into the air layer 11, and reference numeral 18 denotes an exhaust formed between the cover 17 and the outer surface of the decorative board 4 to discharge the air in the air layer 11 downward. Mouth.

Therefore, even if the decorative board 4 receives heat due to the west of midsummer, the air in the air layer 11 is warmed and rises, is discharged from the exhaust port 18, and the cool air from the pit 13 for the line is switched. Cool the bottom of gear 3 and vent 1
4, the air flows into the air layer 11 through the passage 16 and the exhaust port 18
And the solar heat is not conducted into the switchgear 3,
In addition, the heat inside the panel is also cooled by the air flowing through the air layer 11 and discharged.

[0011]

[Effects of the Invention] Since the present invention is configured as described above, the following effects can be obtained. A wiring pit 13 communicates with the base base 2, and a ventilation hole 14 communicating from the inside to the outside of the base base 2 is provided through the air gap 11 between the base base 2 and the side face 5 of the switchgear 3 whose bottom is closed. At the lower end of the decorative panel 4 formed, a passage 16 communicating the ventilation port 14 and the air layer 11 is formed by the extension 15 of the decorative panel 4, and the path 16 and the ground 1 are shut off. An air space 11 is provided between the cover 17 and the outer surface of the decorative board 4.
An exhaust port 18 for discharging the air downward is formed, and the wiring pit 13, the inside of the base 2, the ventilation port 14 of the base 2, the passage 16, the air layer 11 between the side surface 5 and the decorative plate 4, and the cover 17 are formed. Since the ventilation path of the exhaust port 18 is formed,
Even if the decorative board 4 receives heat due to the sunshine, the air in the air layer 11 is warmed and the specific gravity is reduced, and the warmed air is exhausted from the exhaust port 18 of the cover 17, The cool air and the cool air surrounded by the base base 2 below the switchgear 3 enter the air layer 11 through the ventilation opening 14 and are discharged from the exhaust opening 18, and the solar heat absorbed by the decorative plate 4 is used for the switchgear 3. And the heat generated in the panel can be cooled and radiated by the air discharged from the bottom and side surfaces 5 of the switchgear 3, so that the solar radiation is blocked and the heat in the panel is reduced. Can be effectively dissipated.
