HEAT DISSIPATION
The working temperature of the central unit enclosure must not exceed 45 ºC (113ºF). To ensure
that this temperature is not exceeded, the enclosure must have enough surface to evacuate the heat
generated inside and maintain the ambient conditions within the working temperature range.
Calculating the surface needed to dissipate the heat
The expressions have been obtained for an enclosure having a 2 mm wall and made out of aluminum.
When using internal cooling, the fan is located at 30 mm from the bottom.
To calculate the required total surface of the enclosure in order to dissipate the heat generated in
it, the following data must be taken into account.
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
The maximum power dissipated by the CNC is 55 W, power supply not included.
A(m
2
) Total surface required.
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(m
3
/h) Air flow provided by the fan, if there is one.
