Question:
To cool an electronic device, six identical aluminum fins, as shown in the figure below, are attached. Cooling air is available at a velocity of 5 m/s from a fan at 20?C. If the average temperature at the base of a fin is not to exceed 100?C, estimate the maximum permissible power dissipation for the device.
GIVENAluminum fins with air flowing over themAir velocity (U??) = 5 m/sAir temperature (T??) = 20?CMaximum average temperature of the fin base (Ts) = 100?CGIVENASSUMPTIONSSteady state
