The issues of determining the parameters of the thermal model of Peltier elements necessary for its representation in the computational model of the finite element method are considered. It is shown how, using the reference data of the Peltier element, to obtain an equation approximating its effective thermal power. Using this equation, a method is proposed for determining the effective coefficient of thermal conductivity, volume and surface heat flux density of a Peltier element. These parameters allow you to fully describe the element in a finite element calculation scheme. The obtained values were used to calculate a Peltier element thermostat in the Russian CAE computer-aided design system APM WinMachine.
