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/m? ‘K. Determine (a) the rate of heat loss from the electronic device to the surrounding air and (b) the fin effectiveness.
