中文摘要：

研究了相变材料储热对热电模块(thermoelectricmodule,TEM)发电性能的影响。通过将相变材料直接嵌入到TEM与热源接触的位置,当热源停止工作或被移除时,TEM可利用相变材料在升温阶段存储的热能继续发电。实验结果表明,在冷端温度设定的条件下,增大相变材料的高度和直径,可增强嵌入相变材料的TEM的发电性能。在该实验中嵌入相变材料量最大的TEM“d30h8”发电量相较于没有嵌入相变材料的TEM增加了约12.68%。

英文摘要：

The effect of phase change material(PCM)heat storage on the power generation performance of thermoelectric module(TEM)was investigated.Through embedding PCM into the position where the TEM contacted with heat source directly,when the heat source stopped working or be removed,the TEM could continue generate electrical energy by using stored heat energy of PCM during heating process.The experimental results showed that under the condition of cold junction temperature was set,increasing the height and diameter of embedded PCM could enhance the electrical power generation performance of TEM.The electrical power generation of TEM“d30h8”which embedded with the largest amount of PCM was about12.68%higher than that of TEM without embedded PCM in the experiment.
