Description

[Detailed Description of the Invention] This invention relates to a portable and completely enclosed wireless equipment housing housing for accommodating wireless equipment such as a wireless relay station or a telemeter station.

Conventionally, environmental measures such as natural convection, forced ventilation, air conditioning, etc. have been used to reduce the temperature load in radio equipment storage buildings installed in areas where harmful gases are often generated, such as coastal areas, near highways, and heavy industrial areas. It was being executed.

However, when using natural convection or forced ventilation, it is necessary to take in outdoor air, which makes indoor equipment susceptible to deterioration and significantly shortens the lifespan of wireless equipment. Further, when a filter is provided at the air intake port, there are problems such as the need for replacing the filter and the lack of reliability of the filter effect since the function changes depending on the amount of dust.

In addition, when air conditioners and heat pipes are used, the outdoor units of these devices have a short lifespan due to harmful gases, and have the disadvantage that they cannot withstand long-term use.

This idea was made in order to eliminate many of the drawbacks of the conventional radio equipment storage housing mentioned above. A ceiling and a wall are formed by providing a space to serve as a ventilation path and stretching a heat conductive interior material so that the ceiling and the roof, the walls and the outer frame are connected to a plurality of They are connected by heat transfer plates made of metal plates with a Z-shaped cross section, and the bottom of the housing is divided by metal plates at appropriate intervals, and a wire duct is provided, allowing for internal heat collection and external heat dissipation. The purpose of the present invention is to provide a closed-type wireless equipment housing structure with a housing.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

FIGS. 1 and 2 show the front and side views of the storage building according to this invention, and the housing A is equipped with a sealable door 1 at the front, and the door 1 and the outer wall surface 7 of the housing A are shown in FIG. is made of a zinc-treated steel plate coated with a chlorinated rubber paint, and the bottom surface 6 of the housing A is made of a thick zinc-treated steel plate so as to be able to withstand the weight of the contents such as wireless equipment stored inside the housing. It is placed on the base body 8.

Further, the upper roof portion 2 is constructed by assembling panel bodies using galvanized steel sheets as the base material and connecting these panel bodies in the same manner as described above.

As shown in Fig. 5, this panel body has a connecting hole 3a for a bolt or the like in the horizontal direction of the side surface, and has a shape in which the upper end and front part in the vertical direction protrude, and is connected to another panel body of the same shape facing each other. Since the connecting portion 3 is configured to have such a structure, the tightness of the connecting portion 3 after bolting or the like is extremely high.

Furthermore, as shown in FIG. 3, the bottom part 10 of the housing A is provided on the bottom plate 6 via legs 6a and 6b, which have substantially L-shaped cross sections with both ends facing each other, and are spaced apart appropriately. As mentioned above, the wiring duct section 9 is provided on the upper surface of the bottom plate 6, which is thicker than the outer wall surface 7, so as to accommodate the wireless equipment and the cables wired with the equipment. The system is designed to increase heat exhaust efficiency. As shown in FIGS. 3 and 4, the sides and rear of the housing A are provided with an appropriate space relative to the outer wall 7 to form a ventilation path 4.
An interior plate 12 made of aluminum with a large number of punched holes is stretched across this ventilation path 4, one lower end of the interior aluminum plate 12 is connected to the leg 6a, and the other end is connected to the bottom plate 6. The L-shaped joint portion 11a is connected to one end of a ceiling plate 11 made of a punched aluminum plate with through holes arranged in the horizontal direction.

Incidentally, a plurality of metal plates having a substantially square cross section are interposed in the ventilation path 4 between the outer wall 7 and the aluminum interior plate 12, thereby connecting the outer wall 7 and the interior material 12.

The outer wall 7 of the above-mentioned case A is formed of an assembled panel body by connecting single panels similar to the above-mentioned ceiling part, and can be connected to a desired length, so the size of the case A depends on the installation location. This can be changed as appropriate depending on the shape and amount of stored items.

On the other hand, one end of the interior upper end of the door 1, which is attached to the front of the housing A so as to be openable and closable, engages with a joint part 11b having an approximately L-shaped cross section at the lower left end of the ceiling plate 11 made of aluminum having a through hole, and the door 1 can be opened and closed. It is designed to be able to rotate freely.

Further, as shown in FIG. 5, the ceiling section has a structure in which a plurality of heat transfer plates 14 are communicated between the roof 5 and the ceiling plate 11 to dissipate hot air collected at the ceiling section from the roof section 20.

In addition, as shown in Figures 3 and 4, if necessary, the ceiling plate 11 may be installed to reduce the temperature difference inside the containment building.
The fan 16 may be installed using the fan hole 15 provided in the fan hole 15 so as to be in contact with the lower surface of the roof 2 located above the fan hole 15.

The heat transfer plate 14 between the roof part 2 and the ceiling plate 11 is connected in order to facilitate the heat flow due to the temperature inside the case A to be radiated to the outside of the case A, and from now on the internal heat collection and external heat radiation. It forms the ceiling of the mold.

As shown in FIGS. 2 and 3, the roof 2 can have, for example, a sloped roof with a single-sided roof, and the upper ends of the panels constituting the roof 2 can be extended and accommodated. They are inserted and fixed into side holes 5a and 5b near the interior panel at the top of the building.

Further, as a measure against condensation especially indoors in the case A, a dehumidifier 17 is provided on the bottom surface of the case A, and the waste water from the dehumidifier 17 is discharged through a drain.

The wireless equipment storage building of this invention allows natural convection of air in the vicinity of the steel plate roof panel and the aluminum plates with through holes that make up the ceiling within a predetermined temperature range, and also allows the air to flow between the heat transfer plate and the The hot air inside the room is collected by the interior board, which has good heat conductivity and is made of an aluminum board with holes, and is radiated from the outside wall or roof surface.

In this way, as heat dissipates from the outer wall and roof surface, heat exchange between the heat transfer plate and the interior plate is also promoted, so that the effect of activating natural convection within the housing does not continue. It becomes something that can be seen.

Furthermore, when heat is absorbed by the heat transfer plate, the hot air from the heat absorption surface is transferred to other heat dissipation surfaces such as the outer wall or ceiling, which in turn promotes heat transfer to the outside, thus reducing the indoor temperature. This will help regulate the rise.

In this way, the enclosed wireless device enclosure of this invention, which is used in particularly harsh outdoor environments, collects the heat inside the enclosure using heat transfer plates, etc., and uses interior materials on the ceiling or around the enclosure. Since it is designed to radiate heat to the outside through a certain aluminum interior panel, it is suitable as a portable, fully enclosed wireless equipment enclosure for accommodating wireless equipment such as wireless relay stations and telemeter stations, and can be used as a shelter. It is also easy to make it maintenance-free.

In addition, it has an appropriate length so that it can be transported by hand even in places where cars cannot enter, and the desired size can be accommodated by connecting single panels that have an approximately L-shaped cross section with a protruding top and front end. Since it is possible to construct a housing structure, it is possible to install a housing building in less than half the conventional construction period by connecting or disassembling panels according to the installation area, and it is also possible to install various wireless relay stations and river road management telemeters. It is used as a simple radio equipment housing building that can be installed in a housing station building or a wireless relay station under an expressway, etc., and can reduce repair management.

The material of the casing that constitutes the storage building according to this invention is not limited to the above-mentioned steel plates, but can also be assembled from lightweight ALC plates, etc., making it extremely easy to construct compared to conventional construction methods that use cement, gravel, etc. This leads to cost reduction.

Furthermore, in order to increase heat exhaust efficiency, the entire bottom of the enclosure was made into a wiring duct that could accommodate cables and other equipment associated with the installation of wireless equipment, and the interior was painted black, and the exterior surface was painted white or silver. Coating is effective because it improves heat dissipation from the surroundings inside the casing and keeps the solar heat absorption rate of the casing surface low.

As described above, the sealed wireless device housing according to this invention has a structure that increases the shielding effect against external radiant heat such as solar heat, and is suitable for use as an outdoor housing housing exposed to harsh environmental conditions. At the same time, in order to prevent condensation from occurring due to temperature differences inside the housing that makes up the housing facility, a dehumidifier is installed inside the housing and a condensation prevention mechanism is built-in, so this method is not conventional. It is also possible to prevent dew condensation, which was one of the problems of other types of devices, and it has a wide range of applications, making it a suitable closed-type radio device storage building.
