Abstract:The general physical laws for reaching the maximum efficiency of a generator using vehicular exhaust heat have been studied. Based on the physical models of a generator with lumped and distributed parameters, the optimal gas temperature at the outlet of the thermoelectric generator (TEG) and the optimal distribution of gas temperature in the heat exchanger have been found. The basic generator parameters, namely the voltage, power, and efficiency, have been calculated in the steady-state and dynamic modes. The possibility of efficiency improvement by a factor of 1.5 through use of an exponential as compared with an isothermal distribution of heat exchanger temperature has been revealed. Calculations are confirmed by results from testing a prototype vehicular thermoelectric generator.
