Full Text Description
The invention relates to an outdoor housing for
accommodating electronics, in particular components for
telecommunications and data technology, the electronics
being enclosed in a hermetically sealed manner by a first
housing structure, and a second, outer housing structure
being arranged on the first, inner housing structure in
such a manner that a cavity is formed between the housing
structures.
The known outdoor housings for accommodating
electronics can be designed in a hermetically sealed
manner in order to protect the electronics located in the
interior against interfering electromagnetic radiation
and other environmental influences, such as rain.
However, the electronics arranged in the interior of the
outdoor housing produce an electrical power loss, which
is emitted in the form of heat. This heat in turn has
negative effects on the operation of the electronics and
therefore has to be dissipated in some way, despite the
hermetically sealed housing structure. Two alternative
solutions are known for this purpose from the prior art.
On the one hand, double-walled housings are used and, on
the other hand, a second, outer housing is arranged
around the inner housing in such a manner that a cavity
is formed between the housing structures. The principle
of heat dissipation is common to both solutions. The air
flowing through the cavity absorbs part of the heat and
rises upward (chimney effect) . The heated air can be
carried out there via air shafts or gaps. In the event of
external heating, for example by direct solar radiation,
the layer of air furthermore acts as a heat insulator. A
disadvantageous feature of the known outdoor housings is
their lack of flexibility with regard to different
external boundary conditions. For example, if the outer
housing structure is damaged or destroyed, it is
necessary to replace it, entirely or partially. In
addition, because of the continuous increases in
transmission capacities, it is necessary to install new
outdoor housings or to upgrade existing housings.
Repairs, conversion or reinstallation mean that the
previously used inner and outer housing structures, or
the double-walled housings used, cannot be reused because
of damage to them or because of their geometric
dimensions. On the other hand, attention is now being
paid to achieving a harmonious overall aesthetic
appearance in town areas. Outdoor housings, some of whose
colors are completely inappropriate, remain a disturbing
factor. However, if, for example when building a new
estate, the color of the outdoor housings is matched to
the facade color used, the problem is just delayed at the
latest until the next facade renovation.
The invention is thus based on the technical
problem of providing an outdoor housing which is simple
to repair while having the same technical characteristics
and which can be matched to different or changing external
boundary conditions.
The technical problem is solved by the features
of the invention.
of patent claim 1., By designing the outer housing structure
as hollow-section rails, which are detachably
attached to the first, inner housing structure, a cavity,
through which the heat losses that occur can be
dissipated, is formed between the housing structures in
the same way as in the prior art. At the same time, once
built, the outdoor housing can easily be repaired and can
be matched in a flexible manner to changing boundary
conditions. In the event of conversion or upgrading of an
already existing outdoor housing, the hollow-section
rails used can be reused, and additional hollow-section
rails are just arranged on the new, inner housing. Any
required color configurations can be produced very easily
by using colored hollow-section rails. In addition,
assembly of the outdoor housing is simplified since the
hollow-section rails can be handled relatively easily, in
contrast to the previously used, cumbersome housing
structures. Further advantageous refinements of the
preferred features of the invention,
invention result from thepreferred features of the invention
By using the attachment means for the hollow-
section rails in such a manner that they are not accessible
from the outside in the installed state, this avoids
manipulations and vandalism. Any known type of attachment
may be used as the attachment means, the hollow-section
rails preferably being hooked onto the inner housing
structure so that the outer surfaces of the hollow-
section rails do not offer any indication of the attachment.
In a preferred embodiment, the hollow-section rails
are designed as twin rectangular hollow sections, which
have particularly high strength in comparison with
conventional hollow-section rails. Furthermore, the
hollow-section rails can be designed with a holder for
information media, such as advertizing, public transport
schedules or public notices, or else may themselves be
designed as information media. For example, the housing
may be used as a billboard. For design or engineering
reasons, the hollow-section rails may have any required
shape.
The invention is explained in more detail in the
following text with reference to a preferred exemplary
embodiment. In the figures:
Fig.1 shows a perspective illustration of a modular
outdoor housing,
Fig. 2 shows a view of a detail from Fig. 1,
Fig. 3 shows a plan view of the outdoor housing,
Fig. 4 shows a view of a detail from Fig. 3, and
Fig. 5 shows a plan view of a hollow-section rail.
An outdoor housing 1 is illustrated in perspective
in Fig. 1. The outdoor housing 1 comprises three
modules, each of which has its own inner housing 2. The
area which contains the electrical components is arranged
above a base 3, each module preferably being assigned its
own base 3 and an integral base connection being arranged
around the bases. The individual modules are separately
accessible from the outside via doors 5 composed of
hollow-section rails 4,. For clarity, the outdoor housing
1 is illustrated without a roof. As can be seen in
particular from Fig. 2, the hollow-section rails 4 are
arranged abutting the inner housings 2 and are attached
to them, the doors 5 being hinged on adjacent hollow-
section rails 4 or on the inner housing 2 by means of
hinges 6. A cavity is formed between the inner housings
2, which are all hermetically sealed, and the
hollow-section rails 4 which form the outer housing
structure. The heat losses produced in the inner
housings 2 by the electrical components are transmitted
via the outer walls of the inner housing 2 to the air in
the cavity. The heated air rises upward and can leave the
cavity via air shafts or air gaps between the walls and
the roof, so that the heat losses that are produced are
dissipated.
Fig. 3 illustrates a plan view of the outdoor
housing 1 without a roof, and Fig. 4 illustrates a view
of a detail from Fig. 3. The hinge 6 is attached to the
respective inner housing 2 and passes through a hollow-
section rail 4.
Fig. 5 shows a plan view of a preferred embodiment
of a hollow-section rail 4 as a twin rectangular
hollow section, which gives the outer housing structure
particular strength, and in which case the rectangles 7
may have different geometric dimensions.
