Rapid method of defining the quality of multistage thermoelectric cooler based on measurements of voltage from every stage

Abstract

A method for defining the quality of multistage thermoelectric coolers is proposed. This method is based on measurements of voltage from every stage of the cooler with the current on and at the first moment after switching it off. Heat transfer with ambient environment is taken into consideration. This method also takes into account the thermal load for the lower stage received from the upper one. The causes which can lead to the wrong results are also investigated.
