Definitions
- the invention relates to a control cabinet / control box comprising a housing and an electrical or electronic device disposed therein.
- a control cabinet / control box of the type mentioned is basically known.
- control cabinets / control boxes usually takes place via the natural radiation of the outer walls and doors of the housing, on the outside arranged cooling fins, on the inside of the housing mounted heat conducting plates, ventilation inlets and outlets with and without forced ventilation (fans) or built-in or built chillers ( air conditioners).
- the dissipated amount of heat restricts the site of
- An object of the invention is therefore to provide an improved
- the object of the invention is achieved with a control cabinet / control box of the type mentioned, in which a plurality Newcastle disease-on-semiconductor are provided which are each uninterrupted and individually guided through slot-shaped recesses in a housing wall of the housing and protrude inwardly and outwardly beyond this housing wall.
- cooling surface is on the one hand well received, on the other hand, because of the uninterrupted heat conducting plates but also transported well to the outside and is discharged through the provided there cooling surface to the ambient air. A significant noise emission does not occur. Because of the improved cooling can be dispensed with additional units such as fans or refrigerators in many cases, whereby electrical energy is saved. In addition, the measures taken are easy to manufacture, since only plates must be inserted through recesses in the housing wall. Advantageously, the heat conducting plates are clamped in the recesses by providing a corresponding fit, so that no further mounting means are necessary.
- slot-shaped means in the context of the invention, in particular, a height / width ratio of greater than or equal to 50. That is, the slot is significantly wider than the slot height associated slot height.
- the heat conducting plates have a substantially rectangular cross-section, wherein edges may be broken or rounded.
- heat conduction can be used synonymously.
- the housing is continuous or uninterrupted. In this way, the housing is easy to manufacture and stable.
- the electrical or electronic device is thermally conductively connected to at least one of the heat conducting plates. In this way, the removal of heat is more effective.
- electrical or electronic devices may be connected to a heat conduction plate or more bathleitblechen that produce a lot of waste heat.
- Control cabinet / control box can also be installed in exposed rooms or environments.
- the housing is painted and a gap between the recess and the heat-conducting is sealed by the paint, in particular only by the paint. A separate seal is not necessary, making the structure of the cabinet / control box designed particularly simple.
- a method of manufacturing a control cabinet / control box may therefore comprise the following steps:
- the painting can generally be done inside and / or outside.
- the paint can also help to fix the heat conduction in the housing, in which case coatings are preferably used with good adhesive properties and high mechanical stability.
- coatings are preferably used with good adhesive properties and high mechanical stability.
- a powder coating is also a powder coating as
- a method of manufacturing a control cabinet / control box may therefore comprise the following steps: Providing a painted housing with several slit-shaped
- the heat conducting plates compress the paint in the field through the housing wall
- the coating can generally be done inside and / or outside and also help to fix the heat conduction in the housing, again preferably paints with good adhesive properties and high mechanical stability can be used.
- a powder coating is to be understood as a "lacquer layer”.
- the heat conducting plates are made of aluminum, copper or steel. These materials have a good thermal conductivity and are therefore particularly well suited for the proposed purposes.
- the heat conducting plates are arranged on a cover detachably fastened to the housing. In this way, the production or assembly of the cabinet / control box under certain circumstances in a simpler manner possible, for example, if an electrical or electronic device to be connected to the planteleitblechen.
- FIG. 1 shows an exemplary control cabinet / Schalkasten obliquely from above.
- FIG. 2 the cabinet / Schalkasten of Figure 1 partially ..;
- Figure 3 is similar to Figure 2, with only an electrical / electronic device which is connected to the slaughterleitblechen. 4 shows an exemplary control cabinet / Schalkasten with overhead straight intoleitblechen;
- FIG. 5 shows an exemplary cabinet / Schalkasten with overhead
- Fig. 8 is a housing cover obliquely from above and Fig. 9, the housing cover of Fig. 8 in an oblique section.
- DETAILED DESCRIPTION OF THE INVENTION Figures 1 and 2 show a first example of one
- Control cabinet / control box 1 a with a housing 2 and disposed therein electrical or electronic device 3, Fig. 1 obliquely from above and Fig. 2 also obliquely from above, but partially cut.
- the control cabinet / control box 1 a comprises a plurality of heat conducting plates 4, which are each uninterrupted and individually guided through slot-shaped recesses in a housing wall of the housing 2 and protrude inwardly and outwardly beyond this housing wall.
- the electrical or electronic device 3 is thermally conductively connected to at least one of the heat conducting plates 4, as shown for the cabinet / switch box 1 b in FIG. In this way, that of the electric or Electronic device 3 produced waste heat can be directed more efficiently to the outside.
- the heat conducting plates 4 are arranged laterally on the housing 2 and additionally angled on the outside. However, this is also not mandatory for the invention. Rather, it is also conceivable that the heat conducting plates 4 are arranged on another side of the housing 2 and / or run straight. Fig. 4 shows an example of this
- Cabinet / control box 1 c are arranged at the straight heat conducting plates 4 at the top.
- the housing 2 is designed to be watertight and / or gas-tight at least in the region of the heat-conducting sheets 4. In a particularly advantageous embodiment, this is achieved in that the housing 2 is painted and a gap between the recess and the heat-conducting sheet 4 is sealed by the paint 6, in particular only by the paint.
- Fig. 6 shows a first example in the form of an enlarged section in section. Specifically, two arranged in the housing 2 réelleleitbleche 4 are shown, which are covered by a lacquer layer 6. In this example, the paint 6 seals two facing surfaces of a réelleleitblechs 4 and the housing wall in the form of a groove. That is, the housing 2 is painted after mounting the heat conducting sheets 4.
- a method for producing a control cabinet / control box 1 a..1d may include the following steps: Providing a housing 2 with a plurality of slot-shaped recesses in a housing wall,
- Housing 2 are unwetted, but this compress in the area of the passages through the housing wall, as shown by way of example in FIG. 7. That is, the housing 2 is painted prior to assembly of the heat conducting sheets 4.
- a method for producing a control cabinet / control box 1 a..1 d may therefore comprise the following steps:
- the seal between the is only through the paint layer 6. It is also conceivable, however, that alternatively or additionally other measures are taken to seal.
- a seal can be arranged between the at least one heat-conducting sheet 4 and the housing, whereby an arrangement similar to FIG. 7 is achieved.
- the housing 2 may be painted on the outside and / or inside.
- lacquer is also understood, for example, to mean a powder coating or another coating for protecting the housing 2.
- the heat conducting plates 4 may be made of aluminum, copper or steel, for example, and clamped only in the housing 2 or by
- FIGS. 8 and 9 show an example in which the heat-conducting sheets 4 are arranged on a cover 8 detachably fastened to the housing 2, FIG. 8 obliquely from above, FIG. 9 in an oblique cut.
- the cover may form a housing wall, for example a side wall, or only a part thereof.
- the cover 8 has holes for mounting the same with screws.
- the cover 8 but also be attached in other ways, for example by means of a
- a control cabinet / control box 1 a..1 d also include more or fewer components than shown. Location information (eg “top”, “bottom”, “Left”, “right”, etc.) are based on the respective figure described and are in a change in position of the cabinet / control box 1 a..1 d mutatis mutandis to adapt to the new situation.
