Abstract
The analysis of the measurement and calculation results for the main characteristics of the thermoelectric cooling system is carried out. Using temperature and electrophysical parameter measurements for various temperature conditions and operating modes, the values of thermal resistances of heat exchangers, cooling capacity, coefficient of performance and temperature differences on the structural elements were determined. During modeling, heat transfer processes were described by integral relationships, taking into account the measured operating characteristics of the thermoelectric module and the thermal resistances of the heat supply and removal devices. Based on the results of the analysis, a range of power supply current of the thermoelectric module is recommended, which ensures high cooling capacity and efficiency of the cooling system.
