        摘 要:為了研究串聯(lián)熱電片數(shù)量對(duì)熱電發(fā)電系統(tǒng)輸出性能的影響,建立了一套熱電發(fā)電實(shí)驗(yàn)系統(tǒng)。在設(shè)定的9 種工況下,分別串聯(lián)4片熱電片和8片熱電片進(jìn)行實(shí)驗(yàn),測(cè)量記錄系統(tǒng)在開(kāi)路和接負(fù)載情況下的實(shí)驗(yàn)數(shù)據(jù)。分析可知,不接負(fù)載時(shí),串聯(lián)熱電片數(shù)量越多,開(kāi)路電壓就越大。接負(fù)載時(shí),同一工況下,串聯(lián)熱電片數(shù)量越多,熱電系統(tǒng)的輸出功率、電流、電壓就越大,串聯(lián)的熱電片數(shù)量增加一倍,輸出功率增加不止一倍,大大提高了系統(tǒng)的輸出功率;串聯(lián)熱電片數(shù)量越多,熱電系統(tǒng)的內(nèi)阻越大。
        關(guān)鍵詞:熱電發(fā)電;串聯(lián);熱電片數(shù)量;輸出性能

        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
