HEAT DISSIPATION. CENTRAL UNIT (CPU) ENCLOSURE.
Fan whose air flow Q = 102 m³/h facing down.
Heat dissipation by air flow to the outside using a fan.
Heat dissipation by forced convection with hot air flow to the outside using a fan and ambient
air intake through the holes located at the bottom of the enclosure.
For this case, the volume of air flow is calculated necessary to evacuate 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.
Bear in mind that this air flow through the unit extracts hot air to the outside, but it allows dirt
into the enclosure. Thus, a filter should be installed to maintain the ambient conditions
allowed.
