  • Publication number: 20060042675
    Abstract: In order to make a thermoelectric device usable in a high temperature environment of 300° C. or above, the necessity for solder is eliminated by bonding each electrode of a second substrate to one end of each thermoelectric element by using gold. Further, a conductive member, capable of accommodating expansion and contraction of the thermoelectric elements, is provided between each electrode of a first substrate, on which bonding by gold is not performed, and the other end of each thermoelectric element. Additionally, a lid is placed outside to the second substrate, and the lid and the first substrate are coupled so that pressure can be applied between the first and second substrates. Thus, the second substrate, the electrodes and the thermoelectric elements are held. This prevents the thermoelectric elements from being damaged due to thermal deformation as in the case where electrodes are bonded to thermoelectric elements by solder.

  • Publication number: 20060042676
    Abstract: In order that a thermoelectric device is caused to stably operate even under high temperature environment, the thermoelectric device includes: first and second substrates, each being provided with a plurality of electrodes; a plurality of thermoelectric elements arranged between the first and second substrates in such a manner that one ends of the thermoelectric elements are associated with the respective electrodes on the first substrate, and the other ends thereof are associated with the respective electrodes on the second substrate; a defining member defining positions of the respective thermoelectric elements; and a lid disposed outside of the second substrate, and connected to the first substrate in such a manner that pressure is applied between the second substrate and the first substrate.

  • Publication number: 20050211288
    Abstract: In a thermoelectric device, metal fiber nets as conductive members having elasticity are placed between first electrodes and thermoelectric elements, in order to increase productivity and make it possible to reduce variations in performance without impairing the reliability of a slidable structure even if each component is heated to be thermally deformed. This placement prevents the temperature of the metal fiber nets from becoming high in the operation of the thermoelectric device and prevents the elasticity of the metal fiber nets from being lost. Further, this constitution eliminates the necessity for bonding the first electrodes to the thermoelectric elements using solder. Moreover, the elasticity of the metal fiber nets makes it possible to accommodate variations in height among the respective thermoelectric elements when the thermoelectric device is assembled.
