Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shielding plate for shielding an outdoor housing from sunlight, and more particularly to a shielding plate for an outdoor housing which has good shielding efficiency, can be easily manufactured, and is inexpensive.

[0002]

2. Description of the Related Art There are various types of housings to be installed outdoors, and as an important characteristic thereof, a structure for reducing a rise in temperature of articles, devices, and the like housed in the housing is required. For this reason, various kinds of temperature rise reduction means are applied to the structure of the housing itself and its internal structure. On the other hand, an increase in the temperature of an article, an apparatus, or the like in the housing is affected by heat generated from the article or the apparatus itself, and may be caused by irradiation of sunlight. Particularly, in summer, the heat of irradiation of sunlight is large, which has a great influence on the temperature rise of the housing. For this reason, it is necessary to devise a method of shielding the housing from sunlight, but in the related art, there is no shielding plate as in the present invention described below.

[0003]

As a shielding plate for blocking sunlight, it is necessary to have a large surface area, and the surface of the shielding plate must be devised so as to effectively reflect the sunlight so as not to enter the interior. It is. In addition, it is necessary to provide a space between the shielding plate and the housing to reduce the side emission of sunlight toward the housing. In order to increase the surface area of the flat plate, it is necessary to provide irregularities on the surface of the flat plate. In order to reflect sunlight, it is effective to devise an uneven shape and diffuse the sunlight. On the other hand, in order to form unevenness on a flat surface, when the flat surface is a resin material, it can be integrally formed at the time of resin molding. When a protrusion is formed by pressing a metal or non-metal, a warp is generally generated on a flat plate, and a correction process is required after the pressing, which leads to an increase in manufacturing cost and a reduction in yield. Therefore, in the prior art, only a resin material is used as a plate having a protruding portion, and a metal or non-metal plate is rarely used. On the other hand, when the housing is installed outdoors, a resin material is not preferable for durability and deterioration prevention, and it is necessary to use a metal or at least a non-metallic flat plate.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a good effect of blocking sunlight, does not require a repair process at the time of manufacturing, is easy to manufacture, and has a shielding effect on an outdoor housing which can reduce costs. The purpose is to provide a board.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for enclosing a housing, which is placed outdoors, from sunlight to reduce the temperature rise of the housing. A shielding plate, which is formed by pressing and molding a number of protrusions on the surface of a flat plate made of a metal or non-metallic drawing material, wherein the protrusions are The height h from the surface of the flat plate to the top of the inner surface of the projection is 0.5 [m
m] or a plate thickness, and the bottom area A of the inner surface of the protrusion is 3
1 to 60 [mm ² ].

[0006] The distance between the shielding plate and the outer surface of the housing is at least 20 mm or more.

Further, the flat plate is made of a drawn material or a deep drawn material.

The projections formed on the flat plate by pressure molding are of the same or random arrangement, shape and size.

[0009] By press-molding the protruding portion on the surface of the flat plate of the metal or non-metallic drawing material, the surface area of the flat plate is increased and the sunlight is diffusely reflected. Thereby, the cutoff efficiency can be improved. Further, by forming the flat plate from the drawn material and setting the protruding portions to the dimensions described above, the step of correcting distortion and correcting warpage after pressure molding is not required. This allows
Cost reduction can be achieved. In addition, by setting the distance between the outer surface of the housing and the shielding plate to 20 [mm] or more, the side emission of the heating of the shielding plate by the sunlight toward the housing is significantly reduced. Furthermore, by using a deep drawing plate as the drawing plate, even if the thickness of the flat plate is relatively large and the irregularities are high, it is possible to eliminate a correction step after pressure molding. Further, the degree of freedom of the shielding effect can be improved by randomizing the size and shape of the projecting portion outdoors.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a shielding plate of an outdoor housing according to the present invention. 1 and 2
FIG. 1 shows an embodiment of a shielding plate for an outdoor housing according to the present invention. In the present embodiment, the housing 4 is formed of a prismatic cube, and the shielding plate 1 surrounding the housing is formed of a flat plate disposed on each outer surface of the housing with a gap g therebetween, but is of course limited to this. It does not do. Further, each of the adjacent shielding plates 1 may be arranged closely without any gap. The housing 4 accommodates an arbitrary heat source such as an unillustrated article or device.

The shielding plate 1 comprises a flat plate 2 and a projection 3.
The flat plate 2 is made of a relatively thin metal or nonmetal drawing material, and a deep drawing material is desirable. Note that no resin material is used. This is because the housing 4 has a use purpose of outdoor installation. A plurality of protrusions 3 are formed on the flat plate 2 and are simultaneously formed by pressure forming. Further, in the present embodiment, as shown in FIG. 1, the protrusions 3 are arranged at equal intervals in the horizontal direction, and are juxtaposed at equal intervals in the vertical direction. In this embodiment, the arrangement of the protrusions 3 in the adjacent rows is in a staggered state. This is one measure for minimizing the occurrence of distortion and "warpage".

As shown in FIG. 2, the distance g between the inner surface of the flat plate 2 of the shielding plate 1 and the outer surface of the housing 4 is 2 in this embodiment.
0 [mm] or more. If this interval is less than 20 [mm], the heat of the shielding plate 1 heated by sunlight is easily transmitted to the housing 4 side, and has been experimentally confirmed. On the other hand, if it is much larger than 20 [mm], the entire space becomes large, which is contrary to space saving. Therefore, appropriate dimensions are set in consideration of the installation area.

FIG. 3 shows one embodiment of the protruding portion 3, but its cross-sectional shape is not limited to the illustrated one. As shown, the protrusion 3 in the present embodiment has a substantially semicircular shape, and its height dimension h
Is in the range of 0.5 [mm] to a plate thickness, and the bottom area A is in the range of 3 to 60 [mm ² ]. Note that the height h is a dimension from the surface of the flat plate 2 to the top of the inner surface of the protrusion 3, and the bottom area A is the bottom area of the inner surface of the protrusion 3. The reason why the height h and the bottom area A are within the above-mentioned ranges is that regardless of the shape of the projections 3, if the projections 3 are formed within the range of the dimensions, the shielding plate in the pressure molding is formed. This is because it has been proved that no distortion or "warp" occurs.
Of course, there is a relationship with the thickness of the flat plate 2, but in general, the shielding plate 1
In the case of the flat plate 2 having a plate thickness applied to the above, forming the protruding portion 3 within the above-mentioned size range can eliminate a correction step after pressure molding. Note that it is necessary to use a metal or non-metal drawing plate as the flat plate 2, but in particular, by using a deep drawing plate, it is possible to completely eliminate the correction after pressure forming.

4 (a), (b), (c), (d),
(E) shows some embodiments relating to the arrangement of the projections 3, but is not limited to these.
FIG. 4A shows a case where the arrangement of the protrusions 3 in all the rows is the same, and all the protrusions 3 have the same shape. In FIG. 4B, the arrangement of the protrusions 3 in the adjacent row is a staggered arrangement, and is the most general arrangement of the protrusions 3 having the same shape.

FIG. 4 (c) shows the protrusions 3 having the same shape but a random arrangement. FIG. 4D shows a case where the arrangement is the same, but the shapes (dimensions) of the protrusions are different. FIG. 4E shows a case where both the arrangement and the shape (dimensions) of the protrusions 3 are random. In any of the above cases, if the height h and the bottom area A are within the above-mentioned dimensional ranges as shown in FIG.

By disposing the shielding plate 1 having the above structure around the housing 4, it is possible to prevent direct sunlight from being applied to the housing 4 and to reduce the temperature rise of the housing 4. Also,
By forming the protruding portion 3, the surface area of the flat plate 2 is increased, and the effect of blocking sunlight can be improved. Further, as described above, at least 20
By providing an interval of [mm] or more, the housing 4 for sunlight
Can be greatly reduced.

Further, by providing the protruding portion 3, the strength of the flat plate 2 can be improved and the appearance can be improved. Further, since the shielding plate 1 of the present invention does not use a resin material, it can be used outdoors and the durability can be improved. Furthermore,
Forming the protruding portion 3 makes it possible to prevent sticking of the poster. Furthermore, by sticking silicon on the surface of the flat plate 2 and the protruding portion 3, the sticking of the poster is more completely prevented.

[0018]

According to the shielding plate of the outdoor housing of the present invention, the temperature rise due to the solar heat of the housing can be greatly reduced, and
The need for a repair step after pressure molding is eliminated, and manufacturing costs can be reduced. Further, since a metal or non-metal is used, it can be used outdoors, and the strength and appearance can be improved by forming the protruding portions. In addition, the effect of preventing sticking of the sticking paper can be improved.
