  • Choice of material

The choice of material for the enclosure (steel, polyester, aluminium) is essential for ensuring the natural dissipation of calories released by the electrical or electronic devices.






  • Size of the enclosure

The surface of the enclosure acts as a radiator to transfer heat from the inside to the outside (assuming the outside is cooler than the inside). The larger the surface area, the greater the heat transfer rate.
