A total of 10 rectangular aluminum fins (k =203 W/m·K) are placed on the outside flat surface of anelectronic device. Each fin is 100 mm wide, 20 mm highand 4 mm thick. The fins are located parallel to each otherat a center-to-center distance of 8 mm. The temperature atthe outside surface of the electronic device is 60°C. The airis at 20°C, and the heat transfer coefficient is 100 W/m2·K. Determine (a) the rate of heat loss from the electronic device to the surrounding air and (b) the fin effectiveness.

Question
A total of 10 rectangular aluminum fins (k =
203 W/m·K) are placed on the outside flat surface of an
electronic device. Each fin is 100 mm wide, 20 mm high
and 4 mm thick. The fins are located parallel to each other
at a center-to-center distance of 8 mm. The temperature at
the outside surface of the electronic device is 60°C. The air
is at 20°C, and the heat transfer coefficient is 100 W/m2·K. Determine (a) the rate of heat loss from the electronic device
to the surrounding air and (b) the fin effectiveness.
