评价了由Heusler Fe 2 VAl合金组成的热电模块的发电性能。为了构建模块，W掺杂的Fe 2 VAl合金使用粉末冶金工艺制备。在373-673 K的真空热源上，对由18对p-n结组成的组件进行了发电试验。W掺杂降低了热导率，提高了热电优值，提高了转换效率和输出功率。利用Heusler合金的高热电功率因数，获得了0.7W/cm 2的高输出功率密度。该组件具有良好的耐久性，并在空气中的温度循环测试后保持相对较高的输出功率。
Power generation performance of a thermoelectric module consisting of the Heusler Fe2VAl alloy was evaluated. For construction of the module, W-doped Fe2VAl alloys were prepared using powder metallurgy process. Power generation tests of the module consisting of 18 pairs ofp–njunctions were conducted on a heat source of 373–673 K in vacuum. The reduction of thermal conductivity and improvement of thermoelectric figure of merit by W-doping enhanced the conversion efficiency and the output power. High output power density of 0.7 W/cm2was obtained by virtue of the high thermoelectric power factor of the Heusler alloy. The module exhibited good durability, and the relatively high output power was maintained after temperature cycling test in air.
