Rational Design of Thermoelectric Cooling Device for Variable Temperature Operating Conditions

The possibility of rational design of thermoelectric device in systems for providing thermal modes for radioelectronic equipment during operation in various climatic conditions is considered. The aim of the work was to find solutions that allow choosing a variant of thermoelectric device design at a changing temperature of the environment, which ensures a reduction in energy costs and an increase in reliability indicators. The calculations of the basic energy and reliability parameters of thermoelectric devices for various operating modes have been carried out. The influence of the ambient temperature is analyzed and it is shown that the heat load, operating current, power consumption and intensity of failures increase with temperature. The expediency of thermoelectric devices functioning in the mode of minimum failure rate is substantiated, which allows reducing the failure rate by 1.5 times in comparison with the maximum cooling capacity mode.
