with the push towards reducing component size, increasing power dissipation and lowering junction temperature, engineers must utilize different and more effective means for achieving their goals. thermo electric coolers (tecs) are one such means to achieve their ends.

tecs have been on the market for decades and their application in component cooling can be attractive, if they are designed properly or chosen correctly. even though their cop is much lower than a carnot cycle efficiency, they can solve some problems if the fundamentals of a tec are well understood by the engineering team.
