An enclosure box surrounds some electronics that draw 25 W of electrical power. For heat transfer we will just consider the biggest wall and ignore other sides, in this case. The wall is a 0.8 mm thick aluminum (kAL = 200 W/m-C), and 200 cm length x 100 cm width. The outside air is at 20 C and the convection coefficient outside, houtside = 200 W/m2-C due to a fan running. For the inside, hinside = 5 W/m2-C. How hot will the inside air get under these conditions?
