Optimization of Peltier thermocouple using distributed Peltier effect

Calculations of maximum temperature difference and coefficient of performance of double segment Peltier thermocouple are presented. Distinction of thermoelectric properties of p- and n-type segments is taken into account. Obtained results are compared with measured characteristics of manufactured Peltier thermocouples. It is shown that efficiency of thermocouples using distributed Peltier effect can be improved if optimized thermoelectric properties of segments depending on temperature are used.
