Definitions
- the present invention relates to a double-walled container, such as a housing or a tub, with inner and outer walls made of a thermally highly conductive material, e.g. Metal.
- a thermally highly conductive material e.g. Metal.
- the so-called temperature bridge i.e. a thermal connection between the interior and the outer wall are interrupted.
- this temperature bridge is interrupted by separating the inner wall and the outer wall of the container from each other at the thermal zone boundary and in between with a thermally poorly conductive connecting part, e.g. a plastic rail (profile) or a sealing tape.
- a thermally poorly conductive connecting part e.g. a plastic rail (profile) or a sealing tape.
- the manufacturing effort is relatively large, since the parts are made of different materials and must be assembled manually.
- the container according to the invention is characterized in that the cross-sectional area of the inner and / or outer walls is reduced in predetermined areas.
- the container is characterized by an inner wall and outer wall formed in one piece in the region of the hermetic zone boundary. Through this seamless transition between the inner and outer wall These can be produced in one work step, so that an even further simplification of the production process and an even further reduction in the manufacturing effort can be achieved.
- the container is characterized by holes formed in predetermined positions in the walls, which are arranged in one row or in several rows.
- the holes can be spaced apart from one another in a predetermined grid.
- This embodiment allows simple processing of the wall elements by punching, which can be largely automated. By forming holes in one or more rows, a sufficient reduction in the thermally effective cross section can be achieved while maintaining the required mechanical stability.
- the predetermined grid in which the holes are spaced from one another makes it possible to use the holes according to the invention for suspending or fastening further components such as door hinges, shelves, struts, seals or the like. to use and thus to simplify the manufacturing process even further.
- FIG. 1 shows a section of a wall element with an interruption of the temperature bridge in the form known in the prior art
- FIG. 2 shows a cross-sectional view of a wall element section with an interruption of the temperature bridge according to the invention
- Figure 3 is a partial perspective view of a container according to the invention.
- FIG. 1 shows the arrangement known in the prior art with the inner wall 5, the profile 3 made of the thermally poorly conductive material and the outer wall 1
- the space 7 encompassed by this arrangement is filled by an insulator, for example polyurethane foam or glass wool mats.
- Figure 2 shows a cross-sectional view of a wall structure according to the invention.
- the inner wall 5 and the outer wall 1 are formed in one piece together.
- holes 9 are punched out in the inner wall 5 and in the outer wall 1, which reduce the cross section of the walls to such an extent that the thermal resistance is increased, so that the energy loss via the temperature bridge is effectively limited.
- the space 7, which is bordered by the walls 1, 5, is in a known manner, e.g. filled with polyurethane foam or glass wool mats. If necessary, the holes 9 are closed before isolation, e.g. with polyurethane foam, covered with a tape and thus preventing the foam from escaping.
- the insulation is also considerably simplified, since the inner wall 5 and the outer wall 1 are made from one piece, which is bent in a suitable manner, and thus has a considerably higher mechanical strength than that according to the prior art Technique merged three elements.
- the holes 9 are preferably provided in the region of the thermal zone boundary in order to interrupt the temperature bridge as effectively as possible. In this way, efficiencies can be achieved that come close to interrupting the thermal zone boundary with a profile 3 made of a thermally poorly conductive material.
- FIG. 3 shows a partial spatial representation of a cabinet according to the invention.
- the inner walls 5, like the outer walls 1, have holes 9. These holes 9 can be punched out during processing of the wall plate
- the inner wall and the outer wall easily and can be arranged in several parallel rows if necessary.
- the holes 9 with one another and the rows of holes with respect to one another can have predetermined distances which are chosen such that they allow the installation of door hinges without drilling additional holes 9. Furthermore, the installation of shelves or struts is also possible in a simple manner. If they have fasteners in the appropriate Have a distance, so that savings can be made in the subsequent manufacturing steps as well.
- seals can also be attached or replaced in a simple manner if they have fastening elements on their rear side at a hole spacing.
- the holes 9 can have the same shape as required: however, they can also differ from one another in shape and / or size. Thus, e.g. triangular, quadrangular, polygonal, round, non-round, elongated and / or different sized holes may be provided to meet specific requirements.
