On the importance of thermal resistances of the cooling system when choosing a thermoelectric module

Calculations and analysis of the energy characteristics of the cooling and thermal control system are carried out, taking into account the operating characteristics of the thermoelectric module, thermal resistances of heat supply and removal devices, and parameters of the cooled object. The cooling efficiency is compared when using two serial thermoelectric modules with different power. It is shown that a significant factor affecting the efficiency of cooling is the thermal resistance of the devices for supplying and removing heat. Criteria are defined that allow choosing a thermoelectric module for a cooling and thermal control system.
