THERMOELECTRIC CONVERTER

PROBLEM TO BE SOLVED: To provide a thermoelectric converter easily-to-assemble of a board capable of maintaining the performance of the thermoelectric converter at high level while preventing a thermoelectric element from being damaged due to deformation of the board caused from heat.SOLUTION: A thermoelectric converter 1 includes: a first thermal conductive board 10; a second thermal conductive board 20; and plural thermoelectric elements 30 which are disposed between the first board 10 and the second board 20. At least first board 10 is divided into plural areas 10a, and the neighboring areas 10a are connected to each other by a buffer part 11 which elastically absorbs deformation of each area 10a due to heat in plane directions.SELECTED DRAWING: Figure 1 【課題】熱による基板の変形によって熱電変換素子が破損することを抑制しつつ、熱電変換器の性能を高く維持でき、且つ、基板の組み立て作業を容易に行い得る熱電変換器を提供する。【解決手段】熱電変換器１は、熱伝導性の第１基板１０と、熱伝導性の第２基板２０と、第１基板１０と第２基板２０との間に配置された複数の熱電変換素子３０と、を備える。少なくとも第１基板１０は、複数の領域１０ａに分割され、熱による各領域１０ａの面内方向の変形を弾性的に吸収する緩衝部１１によって、隣り合う領域１０ａが互いに連結されている。【選択図】図１
