Thermoelectric device for converting heat into electricity or electricity into heat, has insulating layer formed on first vessel surface, thermoelectric elements with end secured to wiring layer, metal thin wire net, and insulating member

摘要

Thermoelectric device comprises a closed vessel having an internal space made by metal members and two opposing principal surfaces; an insulating layer (6) formed on the first principal surface; a wiring layer (7,11) provided on the insulating layer surface; thermoelectric elements with one end secured to the wiring layer to stand upright and connected electrically; a metal thin wire net (9) arranged on other ends of the thermoelectric elements to connect the thermoelectric elements (3,3a,3b); and an insulating member provided between the wire net and the second principal surface. An independent claim is also included for a method of manufacturing a thermoelectric device. Material of a metal member (5) positioned at least on other ends sides of the thermoelectric elements. Out of the metal members is formed of Kovar(RTM: Not defined) and/or stainless steel. A joined portion for connecting metal members provided to constitute a closed structure of the vessel is formed of an alloy of the material of the metal member and nickel. The insulating member is a spray deposited formed of white alumina, gray alumina, magnesia spinel, chromia, or zircon. The metal thin wire net is wrapped up with a metal foil.
