Two-temperature approach to the thermoelectric cooling problem

The two-temperature model for thermoelectric cooling process study is developed. In this model the electron and phonon temperatures are different. This model can be applied to the design of micro-refrigerators used for the cooling of microelectronic elements. Electron and phonon energy and heat balance equations are obtained as well as their boundary conditions. Electron and phonon temperature distributions are calculated in the linear approximation of the electric current.
