ABSTRACT:
A thermoelectric unit is disclosed having superposed PN semiconductor thermoelectric stages (10, 12) thermally and electrically connected together by a planar ceramic coupler (14) therebetween. The PN semiconductor blocks (16, 18) of each stage are connected by metallic bridging elements (20), which bridging elements are soldered to isolated metallized areas (40) on each face surface of the ceramic coupler (14) to thereby form a thermal path between the stages. Each stage further includes power source tabs (22,24; 26,28), the tabs (26,28) of one stage receiving power from the other stage through electrically conductive metallized edge paths (42, 44) on the ceramic coupler (14). This forms an interstage connection for connecting the PN semiconductor blocks of the one stage to the PN semiconductor blocks of the other stage.
