F or the designer of electronic equipment packing more power into less space, heat is a persistent adversary. The increased density of modern electronic devices increases the amount of heat to be dissipated in a smaller box. A smaller enclosure containing less air also increases the rate at which heat builds up, should forced-air cooling fail.
The choice of overheat protection sensors and strategy depends on value, application, and sensitivity of equipment, installed cost of sensors, and the presence or absence of forced-air cooling. There are numerous options in forced-air cooled circuitry, including redundant overheat protection.
