Optimization of segmented cooling leg

Resumo

A method for calculating the segmented thermoelectric cooling leg in the one-dimensional approximation by the heat balance method with effective values of the thermoelectric parameters, i.e., the conductivity σ, Seebeck coefficient α, and thermal conductivity κ, is proposed. This method accurately accounts for the temperature dependences of σ, α, and κ. The effect of the contact resistances on the resulting efficiency is also adequately taken into account. A method for passing from leg calculation to the thermoelement calculation is presented.
