Aimed at the high temperature of tank’s exhaust, the principle of applying thermoelectric generation technology to tank thermal restraint was analyzed. Its application experiments were conducted to test the exhaust temperature under different rotating speeds, The experiment results show that the thermoelectric generator can output sufficient electric energy to drive fans; the external surface temperature of radiator is reduced by over 65.0% compared with exhaust surface due to the combination effect of thermoelectric conversion, fan cooling and heat radiation; the exhaust surface temperature rise caused by increase of the engine’s rotating speed results in the increases of the temperature difference of the thermoelectric generator’s cold and hot sides, the fan’s driving voltage and heat convection, thus, the effect of fan’s cooling is more obvious than that of the temperature rise caused by exhaust.
