DETAILED DESCRIPTION OF THE INVENTION

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural cooling type outdoor control panel which is installed outdoors where the temperature changes greatly and where corrosive gas or dust is present.

[0003]

2. Description of the Related Art Conventionally, a control panel installed outdoors adopts a closed structure to prevent inflow of rainwater and dust, and a control panel installed inside a housing in order to cope with sunlight rays and temperature changes in the outdoors. Insulation material is installed and a light shielding plate is installed outside.

FIGS. 6 to 8 show a conventional example of such a control panel. FIG. 6 is a front view, FIG. 7 is a side view, and FIG. 8 is a horizontal sectional view.

[0005] In FIGS. 6 to 8, a housing 1 has a sealed structure, a door 2 uses a packing 3 to block the inflow of the atmosphere, and a metal light shielding plate 5 is attached around the entire periphery to prevent sunlight 4. The internal mounting device 6 is mounted on the internal panel 8 so that the mounting screw 7 does not go outside.

[0006]

However, in the above-mentioned conventional structure, the size of the housing is determined by the storage amount of the internal equipment and the amount of auxiliary metal fittings used for assembling and wiring the internal equipment. Therefore, the entire housing becomes large.

[0007] Further, although a part of the sunlight is cut off, there is a problem that the temperature inside the housing follows the change in the outside air temperature, and dew condensation occurs due to a temperature difference between the day and night inside the housing.

[0008] On the other hand, due to the recent rise in land prices, it is desired that the outdoor self-standing board installed outside the building has a reduced site for installation, and an electric component housing which should be housed in an electric room inside the building is also required.
Outdoor installation is required to reduce the size of the building.

The present invention reduces the volume of the housing,
It is an object of the present invention to provide a rational natural cooling type outdoor control panel that effectively prevents dew condensation caused by changes in temperature of sunlight and day and night due to outdoor installation, and also effectively prevents inflow of rainwater and dust. [Configuration of the Invention]

[0010]

SUMMARY OF THE INVENTION The present invention provides a sealed housing for preventing the inflow of rainwater and dust.
Using a light-shielding plate made of plastic with better heat insulation than iron to block sunlight and high temperature outside air, the internal temperature rise due to the heat generated by the housing internal housing equipment is achieved by cooling the outer wall of the housing by natural ventilation of the light-shielding plate. A self-contained outdoor self-supporting panel with reduced heat.A high-insulation plastic light-shielding plate is attached to the outside of the sealed enclosure to block sunlight and high temperatures in the outside air, and to release internally generated heat by natural ventilation. By doing so, dew condensation inside the housing is prevented, and furthermore, by surrounding the outside with a decorative plastic light-shielding plate, it is possible to directly mount the internal articles on the housing, thereby reducing the volume of the housing.

[0011]

1 to 5 show one embodiment of the present invention.

FIG. 1 is a horizontal sectional view, FIG. 2 is a side view, FIG. 3 is a horizontal sectional view, FIG. 4 is a side sectional view, and FIG. 5 is a detailed sectional view of a plastic light shielding plate.

In FIG. 1 to FIG. 5, a housing 1 has a closed structure, a door 2 uses a packing 3 to block the flow to the outside air, and a light-shielding roof 9 and a light-shielding plate 10 made of plastic are attached. .

The light-shielding roof and the light-shielding plates 9 and 10 are made of hard vinyl chloride 11 on the outside, and a foamed plastic material 12
And molded into a concave shape 13.
The light-shielding plates 10 on the side 14 and the side surface 15 are notched at the top and bottom, and have a number of slits 16 at the bottom.

By mounting such a light-shielding plate 10 on the outside of the housing 1, the solar light 4 is blocked, and a change in the outside air temperature is prevented from being transmitted to the inside of the housing to a minimum. An air flow 17 due to natural ventilation is generated through the concave forming portion 13 and the lower slit 16 of the light shielding plate 10 provided on both side surfaces 15 and the back surface 14, and passes between the light shielding plate 10 and the housing. It cools down and promotes heat dissipation inside the housing.

The exterior of the housing is provided with a decorative plastic light shielding plate 10.
By directing the tip of the instrument mounting screw 7 to the concave shaped portion 13 of the light-shielding plate 10, the internal instrument 6 can be easily attached directly to the housing 1 and the internal volume can be reduced.
In this case, a tapping screw made of stainless steel is used as the mounting screw 7 in consideration of sealing degree and rust prevention.

[0017]

As described above, according to the present invention, the enclosure has a sealed structure to block the inflow of outside air, prevent rainwater, dust and the like from entering, and surround the outside of the enclosure with a light-shielding plate. This prevents the internal temperature of the housing from rising due to sunlight, and promotes heat dissipation from the outer wall of the housing by natural ventilation between the outer wall of the housing and the light-shielding plate against the increase in internal temperature due to the heat generated by the storage device inside the housing. In addition, a natural light-cooled outdoor control panel that can reduce the external dimensions of the housing compared to the storage capacity by eliminating the need for an internal panel or wiring hardware by enabling direct mounting of internal equipment using a makeup light-shielding plate is possible. can get.
