  • 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).

  • 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.
