* 18 Watts in cabinet, 328 Watts out through cabinet heat sink
The temperature rise inside a metallic cabinet incorporating only an
internal convection cooling fan can be roughly calculated with the
following formula:
T = W/6S
- T = Temperature rise in cabinet (
°
C)
- W = Heat generation (Watts) by units and modules
- S = Heat radiation surface area (sq. meter) of cabinet
(total cabinet surface area minus any area in contact with the floor or
building wall)
The above equation assumes a closed cabinet with heat dissipated only
through cabinet radiation.
