Analysis of reliability improvement possibilities of thermoelectric cooling devices

Development of a model for predicting the reliability indicators in the design of cascade thermoelectric coolers

“…Moreover, when we take into account the existing market for thermoelectric coolers [13], then it becomes obvious that it is necessary to search for the ways of improving the energy and reliability indicators of the existing thermoelectric modules. The models of interrelation between the indicators of thermoelectric effectiveness and reliability, presented in [14], as well as the influence of re-gimes on the indicators of reliability [15], allow us to argue about the expediency of the given developments. For this purpose, it is necessary at the assigned temperature range to determine basic significant parameters, namely, relative operating currents and relative temperature differentials in the cascades, and then to estimate reliability indicators of energy-efficient CTED.…”
