thermoelectrics are solid-state devices capable of transferring heat across a temperature gradient. as a solid-state technology, there are no moving parts and no working fluids, which translates into simple integration, essentially no maintenance, quiet operation, and acceptable reliability.
for applications involving relatively steady state cooling and low humidity with a continuous and uniform supply of dc voltage, thermoelectric module reliability is extremely high. mean time between failures (mtbfs) in excess of 200,000 hours are not uncommon in such cases and it is generally considered to be an industry standard [6].
in addition, the degree of cooling may be readily controlled by means of the current supplied to the thermoelectrics.
