Thermoelectric Cooling Analysis Using Modified Graphical Method

Comprehensive analysis of thermoelectric cooling systems involves many parametric equations, which require solving complex mathematical or computation-fluid-dynamic (CFD) models. In this study, a Modified-Graphical Method (MGM) based on previous study by Lineykin and Ben-Yaakov is proposed to analyze an active cooling system using thermoelectric module. The MGM provides quicker visualization of the cooling requirement using only common parameters from TEC manufacturers to obtain pertinent design information such as the optimum operating currents, temperature of the hot side and coefficient of performance (COP).
