【Abstract】 The differential equations of heat conduction for thermoelectric devices are established by using the theory of nonequilibrium thermodynamics and the coefficient of performance and the cooling rate of a semiconductor refrigeration device are derived. Moreover, the influence of Thomson effect on the performance of the refrigeration device is discussed in detail. Some new significant conclusions are obtained and some problems widely existing in the related investigations are settled.更多还原
