Calculation and optimization of thermoelectric cooling modes of thermally loaded elements

Abstract

The results of calculating the characteristics of the heat-transfer process in thermoelectric cooling and temperature control are presented. The influence of the inhomogeneity of the heat flux and thermal contacts on the temperature increase of the heat-loaded element has been defined. The analysis of the cooling efficiency depending on the operating characteristics and the current strength of the power supply of thermoelectric modules, parameters of the heat-loaded element and the individual components of the system, and the conditions of the heat exchange with the external environment has been performed. It has been shown that, under certain conditions, the use of the thermoelectric modules cannot lead to a cooling of the element, but rather to heating. The possibility of optimizing the cooling to reduce the temperature of the heat-loaded element and power consumption of the thermoelectric module has been considered.
