Enclosures can be subject to vibrations. Did you know that? Even if they are usually used in static applications, fixed in their position, and even if they do not contain significant sources of vibration, electrical panels often need to be protected from the vibrations present in the installation environment!
What is the origin of the vibrations?
In fact, in some cases, the enclosure itself is mounted on the structure of the machinery or plant source of the vibration itself, or it may happen that it’s mounted on moving parts, such as for example on bridge cranes, or it can be stressed by more or less strong vibrations generated by the surrounding machinery and equipment present in the building, such as presses, hammers, turbines and other machinery. However, even these electrical panels can be subject to overheating, and therefore require some precautions in the design phase, to ensure adequate cooling of the components.
What cooling solutions to adopt?
When it comes to applications where the electrical cabinet is stressed by more or less rapid movements, cooling solutions using compressor refrigeration units are therefore not recommended, as the lubrication of the system may not work optimally and cause damage to the compressor. Obviously we are talking about non-automotive or similar industrial-type cooling units that use components suitable for the sector.
Therefore, the optimal solutions are:
In fact, when the internal/external temperature conditions permit it, these solutions withstand both vibrations and moderately rapid movements.
Furthermore, in addition to being products that are not afraid of vibrations, the fans used on the filter units and on the thermoelectric units themselves do not produce any on their own, as they are dynamically balanced during the production phase.
