Mathematical Model of Thermoelectric Peltier Module

Abstract

TEM (thermoelectric Peltier modules) are devices that convert electrical power in a temperature gradient. Its action is based on Peltier effect. The devices are relatively simple and with small dimensions, they possess a good construction reliability and long service life (over 200,000 hours). They do not have any moving parts or environmentally harmful refrigerants. Modern TEM are highly effective—with power up to several hundreds of watts. In recent years, thermoelectric cooling systems have been widely used. They have been applied in modern vehicles for cooling and preserving products during their transportation, in portable cooling bags, computer, military and medical equipment. Usually in TEM catalogue data present some transducer characteristics and maximum parameters, but they are insufficient to create highly efficient thermoelectric systems. The purpose of this article is to offer a relatively easy method for modeling of TEM, and the results are presented in tabular and graphic form by Matlab.
