Why this formula appears here
Heat removal is fundamentally a problem of area, not of power alone. The quantity engineers actually design against is heat flux, power divided by the surface area it must leave through: . with q'' expressed in watts per square centimetre. Doubling a chip’s power without changing its package size doubles q'' , and every downstream cooling decision in this article follows from trying to hold q'' within what a given cooling medium can actually carry away from that specific surface before the silicon beneath it exceeds its rated temperature.

Symbol P
P occurs above the fraction bar. The numerator is divided by the entire denominator below it.
