Question 1-2 Cooling of an electronic power transistor is assisted by attaching it to an aluminium heat sink. The electrical power to be dissipated is 3.0 watts, the exposed surface area of the heat sink is 0.01m², the convection heat transfer coefficient is 5.0 W/m²K and the ambient temperature is 20°C. Assuming steady state conditions and ignoring radiation effects, what will be the surface temperature of the heat sink? BEST-ROM Power Transistor alone Attached to Heat Sink
