PURPOSE:To enable effective heat absorption and radiation while obtaining electric insulation as well as to facilitate installation by arranging a multiplicity of semiconductor elements for thermoelectric conversion between a pair of heat absorbing and heat radiating plates, each of the elements being adhered at one end to each of the electrode foils facing to each other. CONSTITUTION:When a DC power supply is connected, a metallic plate 1 is cooled and a metallic plate 2 is heated. On the other hand, when the power supply is connected reversely, the metallic plate 1 is heated while the metallic plate 2 is cooled. Further, when a load instead of the power supply 31 is connected between terminals 27 and 28 so as to heat or cool the metallic plate 1 and to cool or heat the metallic plate 2, a predetermined power can be supplied to the load. Accordingly, in the operation of this thermoelectric converter as mentioned above, the metallic plate 1 and 2 holding semiconductor elements 25 and 26 can function more efficiently as heat absorbing or heat radiating plates than conventional holding plates of ceramic or the like, whereby heating/cooling and electricity generation can be performed efficiently. |
