Electronic power devices are mounted to a heat sink having an exposed surface area of 0.045 m² and an emissivity of 0.80 (Fig. P15.21). When the devices dissipate a total power of 20 W and the air and surroundings are at 27°C, the average sink temperature is 42°C. What average temperature will the heat sink reach when the devices dissipate 30 W for the same environmental conditions?
