This study presents a simple method for extracting the performance parameters of a commercial thermoelectric cooler (TEC). Based on MATLAB, the characteristic curves of thermoelectric cooler manufactures are fitted by least square method, and the functional relationship between current and cooling capacity under different temperature differences is obtained. By the obtaining data of current, temperature, and cooling capacity, using the multivariate linear equation solves Seebeck coefficient α, electric resistance R and the thermal conductivity K. Compared with the experimental results, the extracted material parameters have the advantages of simplicity, convenience and high precision. It can facilitate engineering personnel to predict and select thermoelectric cooler (TEC).
