2.3 Heat dissipation by air flow to the outside using a fan
Heat dissipation by convection forcing hot air flow to flow outside with
a fan and ambient air input through the holes of the bottom surface
of the enclosure.
For this case, calculate the necessary air flow that the fan must supply
to dissipate the heat generated inside the enclosure. The fan's air flow
is calculated according to the power dissipated by the CNC and the
fan itself as well as the inside and outside temperatures.
It must be borne in mind that this air flow through the unit allows
extracting hot air out, but it may let dust in. A filter should be placed
in order to maintain the permitted ambient conditions.
