Modeling of heat transfer in the heat supply device of the thermoelectric cooling unit

The heat transfer process in the heat supply device of the thermoelectric cooling unit is considered. From the numerical solution of two-dimensional problems of heat conduction, the values of thermal resistances of the heat distributor and air heat exchanger are obtained. The dependence of the cooling capacity of thermoelectric modules on the current strength is calculated for two characteristic values of the total thermal resistance of the heat supply device. The analysis of the operating modes of thermoelectric modules and the choice of power supply parameters to eliminate the thermal imbalance caused by the difference in thermal resistance of the parts of the air heat exchanger was carried out.
