To calculate the total surface required for the enclosure, in order to dissipate the heat
generated in it, the following data must be considered.
Dissipating surface.
Only surfaces dissipating heat by convection will be considered, the top and the rear of the
enclosure. The rest of the surfaces are not to be considered when calculating the total
surface.
Power dissipated by the CNC.
To calculate the dissipated power, all the elements that are inside the enclosure must be
taken into account.
Data Units Meaning
A (m²) Total surface needed.
P (W) Total power dissipated by all the elements that generate heat inside
the enclosure, including the power supply and the fan, if there is one.
Ta (ºC) Ambient temperature (outside the enclosure).
Ti (ºC) Temperature inside the enclosure.

t (ºC) Temperature difference (Ti-Ta).
Q (m³/h) Air flow provided by the fan, if there is one.
Element Dissipated power
ICU central unit. 85 watts.
