An heat sink must dispose a thermal power of 325W keeping the base temperature at 75°C when the environment is at 25°C (h=15 W·m-K). The heat sink base is 15x15 cm, the step is of 5 mm and thickness of the fin is 1 mm. Verify if it's convenient to use the heat sink to dispose the thermal power and then calculate the length of the heat sink if it's made of brass (n=105 W.m .K) and then calculate its efficiency.
