The Influence of Engine Speed and Heat Dissipation of Thermoelectric Modules on Exhaust Thermoelectric Generation
In order to improve the recovery and utilization rate of a large amount of waste heat in engine exhaust gas,an experimental platform for engine exhaust waste heat thermoelectric generation was built,and the effects of engine speed and cold end heat dissipation of thermoelectric generation modules on thermoelectric conversion were studied.The results show that after the engine starts,the voltage,current,and power of the thermoelectric module will experience a sudden increase and then keep a stable state;The higher the engine speed,the greater the power generation of the thermoelectric module.However,the power generation is limited by the inability of the cold end of the thermoelectric module to dissipate heat in a timely manner,and the power generation cannot continue to increase with the increase of engine speed.By strengthening the cold end heat dissipation of the thermoelectric module,the power generation of the thermoelectric module can continue to increase with the increase of engine speed.
