    摘 要:为了研究串联热电片数量对热电发电系统输出性能的影响,建立了一套热电发电实验系统。在设定的9 种体育下注网站况下,分别串联4片热电片和8片热电片进行实验,测量记录系统在开路和接负载情况下的实验数据。分析可知,不接负载时,串联热电片数量越多,开路电压就越大。接负载时,同一体育下注网站况下,串联热电片数量越多,热电系统的输出功率、电流、电压就越大,串联的热电片数量增加一倍,输出功率增加不止一倍,大大提高了系统的输出功率;串联热电片数量越多,热电系统的内阻越大。

    Abstract: In order to study the influence of the number of series thermoelectric tablets on the output performance of the thermoelectric power generation system, an experimental system of thermoelectric power generation was established.Under the set nine working conditions, four thermoelectric tablets and eight thermoelectric tablets are connected in series to conduct experiments, and the experimental data of the system under open circuit and load are measured and recorded.Analysis shows that when there is no load, the greater the number of series thermoelectric tablets, the greater the open circuit voltage.When connected to a load, the greater the number of series thermoelectric tablets in the same working condition, the greater the output power, current and voltage of the thermoelectric system.While the number of thermoelectric tablets in series is doubled, and the output power is more than doubled, which greatly increases the output power of the system; the greater the number of thermoelectric tablets in series, the greater the internal resistance of the thermoelectric system.
    Key words: thermoelectric; series; thermoelectric chip number; output performance
