Question details


1-86 Consider a sealed 20-cm-high electronic box whose base dimensions are 50 cm x 50 cm pace in a vacuum chamber. The emiss v o the outer surface of he box s the electronic components in the box dissipate a total of 120 W of power and the outer surface temperature of the box is not to exceed 56.8°C, determine the temperature, up to 2 decimal places, at which the surrounding surfaces must be kept if this box is to be cooled by radiation alone. Assume the heat transfer from the bottom surface of the box to the stand to be negligible. 50 cm 50 cm 120 w 0.95 Electronic box 20 cm Stand Given: σ = 5.67 x 10-8 W/m2 K4 Surrounding temperature206.8 C
