Heat is generated in electronics and other electrical systems by resistive heating, hysteresis losses, eddy currents, and switching activities. The faster a micro-chip performs, the greater the rate of heat generation, and the smaller the chip, the greater the rate of heat flux generated. Thus, as electronics technologies advance, thermal systems designers are presented with even more complex problems as to how to extract heat from micro-electronics, printed-circuit boards, electronics racks, thyristor assemblies, transformers, rotating electrical machinery, space vehicles, aerospace structures and control systems.
