Choice of mode of operations of the thermoelectrical cooling device, ensuring the minimal failure rate

Abstract

A comparative analysis of TCD reliability has been carried out for different current modes. The paper presents relations allowing to determine the relative value of the operating current at a predetermined temperature difference, which provides the minimum failure rate. The possibility of predicting the reliability of devices at the design stage is shown.
