Abstract: A thermoelectric element module has P-type thermoelectric materials and N-type thermoelectric materials alternately joined between a pair of substrates. The thermoelectric materials include a thermoelectric mixture powder in which a thermoelectric material powder and a low-melting metal powder are mixed at a predetermined ratio. The thermoelectric mixture powder is thermally treated at a temperature lower than a melt point of the thermoelectric material, the thermoelectric mixture powder is formed as the low-melting metal is melted, and at the same time both ends of the thermoelectric materials are joined to the pair of substrates. A method for manufacturing such a thermoelectric material is also provided.
Abstract translation: 热电元件模块具有交替地接合在一对基板之间的P型热电材料和N型热电材料。 热电材料包括以预定比例混合热电材料粉末和低熔点金属粉末的热电混合物粉末。 热电混合物粉末在低于热电材料的熔点的温度下进行热处理，在低熔点金属熔化时形成热电混合粉末，同时将热电材料的两端与 一对基板。 还提供了一种用于制造这种热电材料的方法。
