Recently, thermo-electric cooling technology (TECT) had developed as one of the most low-energy-consumption and effective approaches of electronic cooling. The present research gave detailed survey regarding TECT in order to provide a thorough understanding of thermo-electric applications in the electronic cooling. The thermo-electric physical parameters, which include the thermal conductivity K, Seebeck coefficient S, and electric resistance R, are highly influenced by the temperature degrees of the thermo-electric cooling and heating sides and were simplified to constants in a case when the thermo-electric cooling model has been established theoretically. In addition, a total of two systematical solution techniques, namely, effectiveness-number of the transfer units and thermal resistance network, were developed to explain coefficient of performance (COP). The impacts of air temperature, cooling load, and all of the thermal conductance in the heating side on performance of the cooling were investigated, with surface temperature of the electronic devices and COP serving as assessment indices. According to our findings, thermal control for the high heat flux electronics might be accomplished through improving heat transfer in hot side of thermo-electric system and increasing the number of the thermo-electric coolers. Regulating parameters and modelling for the practical applications were provided, and cooling capability of thermo-electric technology for electrical devices has the potential to be developed further.
