The outdoor installation housing shown in FIG. 1 includes a communication device (electronic device) 1 that generates heat, a box-shaped internal housing 2 in which the communication device 1 is mounted, and a box-shaped external housing that houses the internal housing 2 ( Housing) 3 and an armor door structure 4 installed in openings provided on the upper and lower sides of the front, rear, left, and right side surfaces of the outer housing 3. Two armor door structures 4 are installed in each opening. The inner casing 2 is a sealed casing or the like for the purpose of waterproofing.

  FIG. 2: is the top view (a) which shows the armor door structure of the housing | casing for outdoor installations concerning Embodiment 1 of this invention, and a front view (b). Moreover, FIG. 3 is explanatory drawing which shows the armor board which comprises the armor door structure of the housing | casing for outdoor installation which concerns on Embodiment 1 of this invention. 2 and 3, the same or corresponding parts are denoted by the same reference numerals.

  The armor door structure 4 shown in FIGS. 2 and 3 is formed by attaching a plurality of armor plates 6a, 6b to a frame 5 so that the long sides are vertical, and arranging the armor plates 6a, 6b in parallel. . The armor plates 6b are attached to both ends with a plurality of armor plates 6a in between. These armor plates 6a and 6b are provided with a protrusion 7 at the end of the upper end surface and a protrusion 8 at the end of the lower end surface. The projections 7 are fitted into shaft holes (not shown) provided at the upper end of the frame body 5, and the projections 8 are fitted into shaft holes (not shown) provided at the lower end of the frame body 5. Thereby, each armor door 6a, 6b is rotatably held by the frame 5 with the projections 7, 8 as the rotation axis.

  In addition, the armor plate 6a includes an engaging piece 9 at the approximate center of the upper end surface and an engaging piece 10 at the approximate center of the lower end surface. The armor plate 6b has a screw hole 13 in the approximate center of the upper end surface and a screw hole 14 in the approximate center of the lower end surface. The engaging pieces 11, 12 are fitted into these screw holes 13, 14.

  A long hole 18 is formed in the connection fitting (connection portion) 17, and a long hole (not shown) is formed in the connection fitting (connection portion) 19. The hole widths of these long holes are formed such that the engagement pieces 9, 10, 11, 12 are just fitted. Then, the engagement piece 9 attached to the upper end surface of the armor plate 6a and the engagement piece 11 attached to the upper end surface of the armor plate 6b are mounted in the long hole 18 formed in the connecting bracket 17 on the upper end side of the frame body 5. . Moreover, the engagement piece 10 attached to the lower end surface of the armor plate 6a and the engagement piece 12 attached to the upper end surface of the armor plate 6b are attached to the long hole provided in the connecting metal fitting 19 on the lower end side of the frame body 5.

  The engaging pieces 11 and 12 have heads 11a and 12a whose outer diameters are increased so that the connecting fittings 17 and 19 do not come off from the engaging pieces 11 and 12. When the engaging piece 11 is fitted into the screw hole 13, the head portion 11 a holds the connection fitting 17 at the upper end of the frame body 5. Similarly, when the engagement piece 12 is fitted into the screw hole 14, the head portion 12 a holds the connection fitting 19 at the lower end of the frame body 5. By fitting the engagement pieces 11 and 12 of the armor plate 6a attached to both ends of the armor door structure 4 into the screw holes 13 and 14, the connecting metal members 17 and 19 and the armor plates 6a and 6b are fixed, and the frame 5 and each The mounting angle with the armor plates 6a and 6b is also fixed.

  Since these connection fittings 17 and 19 connect the plurality of armor plates 6a and 6b, by operating the connection fitting 17 or the connection fitting 19, the attachment angle of the armor plates 6a and 6b can be adjusted with the projections 7 and 8 as the rotation axis. Can be changed in conjunction with one at a time. In the present embodiment, by moving the connecting bracket 17 shown in FIG. 2B in the left-right direction, the side surface on which the armor door structure 4 is formed and the armor plates 6a and 6b are approximately 180 degrees from the attachment angle. The mounting angles of the plurality of armor plates 6a and 6b can be collectively adjusted up to the moved mounting angle. 2A, the mounting angle of the armor plates 6a, 6b of the right armor door structure 4 is approximately 45 degrees, and the mounting angle of the armor plates 6a, 6b of the left armor door structure 4 is approximately. It is 135 degrees.

  As shown in the cutout portion of FIG. 1B, the hot air (indicated by an arrow 20) radiated from the internal housing 2 in which the communication device 1 that generates heat is radiated has a property of flowing from bottom to top against gravity. The armor door structure 4, which is a longitudinal slit installed in the opening of the external housing 3, does not block the hot air 20 that rises because the armor plate is arranged along the direction of gravity, and the inside of the external housing 3 Therefore, the hot air 20 can be efficiently discharged out of the outer casing 3. Therefore, the temperature of the communication device 1 and the internal housing 2 in the present embodiment is lower than that of a built-in outdoor housing provided with a conventional horizontal slit armor door structure.

  Next, an example of installation of a case for outdoor installation will be described. FIG. 4 is a plan view showing an installation example of the outdoor installation housing according to the first embodiment of the present invention. In FIG. 4, the same or corresponding parts as those in FIGS. The outdoor installation housing shown in FIG. 4 is an example in which the front outer wall 3b of the external housing 3 is installed outdoors with the south side facing.

  When the front outer wall 3b is installed in the south direction, the armor plates of the armor door structures 4a and 4b installed on the side outer wall 3a constituting the outer casing 3 are fixed at an attachment angle of 135 degrees with respect to the side outer wall 3a. did. Further, the armor plates of the armor door structures 4c and 4e installed on the front outer wall 3b were fixed at an attachment angle of 45 degrees with respect to the front outer wall 3b, and the armor boards of the armor door structures 4d and 4f were fixed at 135 degrees. Similarly, the armor plates of the armor door structures 4g and 4h installed on the side outer wall 3c are fixed at an attachment angle of 45 degrees, and the armor panels of the armor door structures 4i and 4k installed on the rear outer wall 3d are fixed at 45 degrees, and the armor door structure 4j , 4l armor plate was fixed at 135 degrees. The number of armor plates to be attached to each armor door structure, the interval between them, the attachment angle, etc. may be appropriately determined according to the size of the case for outdoor installation, the direction of installation, the environmental characteristics of the installation location, and the like.

  Sunlight incident from a direction parallel to the armor plate 6 of the armor door structure 4 penetrates most widely into the outdoor installation housing. In the example of sunlight shown in FIG. 4, it is assumed that sunlight is incident in the direction indicated by the arrow 21 from the true south on the front outer wall 3b side. Sunlight 21 indicated by an arrow only partially enters the outdoor installation housing from the gap 22a between the armor door structures 4c and 4d installed on the front outer wall 3b and the gap 22b between the armor door structures 4e and 4f. Further, with respect to the other outer walls 3a, 3c and 3d, the solar 21 and the solar radiation heat 23a and 23b are made parallel to the armor plate by adjusting and fixing the armor plate mounting angle of each outer wall in advance according to the direction. And does not enter the interior of the outdoor housing. Therefore, the internal housing 2 can be sufficiently shielded from solar radiation heat.

  In addition, even when sunlight enters from a direction different from the example of sunlight shown in FIG. 4, the armor door structure installed on each of the outer walls 3a, 3b, 3c, 3d according to the direction of installation of the case for outdoor installation Since the mounting angle of the armor plate is adjusted and fixed by operating the connecting metal fittings, there is almost no armor plate oriented in parallel to sunlight. Therefore, similarly to the example shown in FIG. 4, sunlight enters only an extremely narrow area inside the outdoor installation housing, and therefore the internal housing 2 can be sufficiently shielded from solar radiation heat. By improving the heat dissipation, it is possible to prevent the life deterioration of the communication device 1 due to the influence of heat or the like.

  As described above, according to the first embodiment, the externally installed housing covers the opening on the side surface of the external housing 3 that houses the internal housing 2 on which the communication device 1 is mounted. The armor door structure 4 includes a plurality of armor plates 6a and 6b arranged side by side, and the armor door structure 4 is configured such that the armor plates 6a and 6b whose long sides extend in the gravitational direction are juxtaposed in a direction perpendicular to the gravitational direction. For this reason, the rising air is not blocked by the armor plate as seen in the conventional armor door structure of the lateral slit, and the hot air generated by the heat generated by the communication device 1 and the internal housing 2 is discharged outside in the upward direction. Thereby, heat dissipation improves and there exists an effect which further reduces the temperature of an internal housing | casing.

  Moreover, according to Embodiment 1, it comprised so that the attachment angle of the armor boards 6a and 6b of the armor door structure 4 might be changed according to the direction to which the side surface of the external housing 3 to which it attaches turned. Therefore, it is possible to block the sunlight in almost all directions incident on the outer casing 3 to block the solar radiation heat, and has an effect of further reducing the temperature of the inner casing.

  Furthermore, according to Embodiment 1, it comprised so that the connection metal fittings 17 and 19 which connect several armor boards 6a and 6b could be provided. Therefore, there is an effect that the mounting angles of the armor plates 6a and 6b installed in the armor door structure 4 can be changed all at once.

Embodiment 2. FIG.
In Embodiment 1 described above, the mounting angle of the armor plate having the armor door structure attached to the outdoor installation housing is adjusted and fixed in advance according to the installation direction. In the second embodiment, an armor door having an armor door structure is fixed in advance at a predetermined mounting angle regardless of the installation direction.

  FIG. 5: is the top view (a) which shows the housing | casing for outdoor installation which concerns on Embodiment 2 of this invention, a partially notched front view (b), and a side view (c). Since the configuration for the outdoor installation shown in FIG. 5 is the same as that of the configuration for the outdoor installation shown in FIG. 1 of Embodiment 1 except for the armor door structure 24, detailed description thereof is omitted. Moreover, FIG. 6 is a perspective view which shows the armor door structure of the housing | casing for outdoor installation which concerns on Embodiment 2 of this invention. The armor door structure 24 shown in FIG. 6 has a long side of the armor plate 26 vertical, and a short side is attached to the wall surface of the external housing 3 to which the armor door structure 24 is attached. Attach to body 25.

The plurality of armor plates 26 of the armor door structure 24 are radially spread from the inside to the outside of the external housing 3 when viewed from the direction of gravity. The armor plate 26 that is closer to the center of the armor door structure 24 is perpendicular to the wall surface of the external housing 3, and the armor plate 26 that is closer to both ends is horizontal to the wall surface and spreads to the left and right. The armor door structure 24 in which each armor plate 26 is radially fixed to the frame body 25 is installed in all openings provided in the external housing 3.

  As shown in the cutout portion of FIG. 5A, the armor door structure 24, which is a vertical slit installed in the opening of the external housing 3, is heated to the outside of the external housing 3 as in the first embodiment. Can be discharged efficiently. Therefore, the temperature of the communication device 1 and the internal housing 2 in the present embodiment is lower than that of a built-in outdoor housing provided with a conventional horizontal slit armor door structure.

Here, a case where sunlight 28 enters from the direction indicated by the arrow toward the front outer wall 3b of the external housing 3 will be described as an example.

  Sunlight incident from the direction parallel to the armor plate of the armor door structure 24 penetrates into the outer casing 3 in the widest range, but the sunlight incident range in which the sunlight 28 and the armor plate are parallel and the sunlight 28 enters. 29a, 29b, and 29c are limited. That is, compared with the outer wall area of the external housing 3, the area where sunlight enters the inside is extremely narrow. Therefore, the internal housing 2 can be sufficiently shielded from solar radiation heat.

  In addition, even when sunlight is incident from a direction different from the example of sunlight shown in FIG. 7, since the armor plate mounting angle is slightly changed for each armor plate and fixed, there is almost no armor plate parallel to sunlight. . Therefore, similarly to the example shown in FIG. 7, sunlight enters only an extremely narrow range inside the outdoor installation housing, and therefore the internal housing 2 can be sufficiently shielded from solar radiation heat. By improving the heat dissipation, it is possible to prevent the life deterioration of the communication device 1 due to the influence of heat or the like.

  As described above, according to the second embodiment, the armor door structure 24 has a plurality of armor plates 26 arranged in a radial pattern when viewed from the direction of gravity so that the interval between the ends of the adjacent armor plates 26 is wider than the interval between the other ends. It was configured to be installed. Therefore, in addition to the effects obtained by the configuration of the first embodiment, the solar radiation heat can be shielded by blocking sunlight in almost all directions incident on the outer casing 3, and the temperature of the inner casing Has the effect of further lowering.

  In the second embodiment, the armor plate 26 is configured to be radially open to the outside of the external housing 3, but may be configured to be radially open to the inside of the external housing 3. Even in this configuration, the same effect can be obtained.

  In addition, although the housing | casing for outdoor installation by Embodiment 1 and Embodiment 2 of this invention was the structure which accommodates the communication apparatus 1 inside, it is not limited to this. However, the present invention is particularly effective when the high heat generation unit in which an electronic device having a large heat generation amount is housed is housed.
