稳态平板法在热电器件热电转换效率测试中的应用

摘要

将稳态平板法测导热系数的实验应用于热电器件热电转换效率的测试，通过测量输入器件的传热速率和负载的输出电功获得热电器件的热电转换效率。研究发现，稳态平板法可以测量工作温度在室温到100℃范围内热电器件的热电转换效率。%We investigated the measurement of thermoelectric conversion efficiency by using steady-state plate through the test of the rate of the heat transfer and the output of the load.We found that steady-state plate can be used to measure the thermoelectric conversion efficiency of the thermoelectric device working in the temper-ature range from room temperature to 100℃.
