UDC 621.362-192 The operating mode of the two-cascade thermoelectric cooling device providing the minimum failure rate Socheslav D. P. Keywords: thermoelectric cooling device, failure rate, probability of failure-free operation, operation mode. The model of interrelation of reliability indicators and the basic significant parameters of the two-cascade thermoelectric cooling device (TED) with consecutive electric connection of cascades is considered. The relations are received allowing to estimate reliability indicators, namely failure rate at construction two-cascade ÒED working in current mode, providing the minimum failure rate in a wide range of temperature drops taking into account thermal loading.Possibility of use of this mode when the prevailing requirement is maintenance of the minimum failure rate and the maximum probability of non-failure operation cascade TED is shown.
