換装置の製造コストを低減し得る。■Since multiple thermoelectric elements are held by an insulating holder made of a material such as styrofoam, the positions of the upper and lower insulating flat plates, which are placed opposite to each other on both ends of the thermoelectric elements, are Positioning can be performed reliably and easily without shifting, and the number of assembly steps can be reduced. As a result, the manufacturing cost of the thermoelectric conversion device can be reduced.
■上記のような絶縁性保持体により熱電素子を位置決め

熱電素子は、絶縁性保持体と固着されることなく遊嵌状
態になっているため、熱電素子に無理なストレスを付与
することがなく、したがって熱電素子の特性の劣化、破
壊等のおそれもない。■ Even if the thermoelectric element is positioned using the insulating holder as described above, it will only be inserted into the thermoelectric element insertion hole, and the thermoelectric element will be loosely fitted without being fixed to the insulating holder. Therefore, no unreasonable stress is applied to the thermoelectric element, and therefore there is no risk of deterioration or destruction of the characteristics of the thermoelectric element.
■各熱電素子は、その周囲を発泡スチロール等の断熱材

構造の熱電変換装置に比較して熱交換効率が向上する。■Since each thermoelectric element is surrounded by an insulating holder made of a heat insulating material such as expanded polystyrene, there is no direct contact with the outside air, which makes it more effective than thermoelectric conversion devices with conventional structures. Heat exchange efficiency is improved.
