A logic chip used in a computer dissipates 3 W of power in an environment at 120°F and has a heat transfer surface area of 0.08 in2. Assuming the heat transfer from the surface to be uniform, determine (a) the amount of heat this chip dissipates during an eight-hour workday in kWh and (b) the heat flux on the surface of the chip in W/in2.
What will be an ideal response?
A logic chip in a computer dissipates 3 W of power. The amount heat dissipated in 8 h and the heat flux on the surface of the chip are to be determined.
Assumptions Heat transfer from the surface is uniform.
Analysis (a) The amount of heat the chip dissipates during an 8-hour period is
