Description

【０００１】
【産業上の利用分野】
本発明は、熱電変換装置に関する。
【０００２】
【従来の技術】
この種の従来技術としては、例えば実開昭６２−９７４６７号公報に開示される技術が知られている。これは、放熱体と伝熱ブロックとの間に熱電変換素子を狭持した状態で、ネジ結合したものである。
【０００３】
【発明が解決しようとする課題】
上記した従来技術においては、ネジが過度に締め込まれることを防止するためにスペーサを介してネジ結合しているが、この構成によると、スペーサや熱電変換素子や伝熱ブロックの寸法のばらつきによって、ネジの締付力が直接に熱電変換素子に伝達される場合が生じる。これにより、熱電変換素子が破損する場合がある。
【０００４】
本発明は、熱電変換素子に過大な応力が掛かることのない熱電変換装置の提供を技術的課題とする。
【０００５】
【課題を解決するための手段】
上記した技術的課題を解決するため請求項１の発明において講じた技術的手段は、ハウジングと、ハウジングに結合された第１熱交換部材と、第１熱交換部材に一方の熱交換面が接触している熱電変換素子と、熱電変換素子の他方の熱交換面に接触すると共に、ハウジングの係止部に弾性体シールを介して係止され、熱電変換素子と係止部に狭持された状態で保持される第２熱交換部材とを備え、熱電変換素子は、前記弾性体シール及び前記第２熱交換部材を介して前記ハウジングの係止部と前記第１熱交換部材とに挟持されていることを特徴とする熱電変換装置としたことである。
【０００６】
上記構成の本発明においては、熱電変換素子への通電方向を切り換えるだけで、第１及び第２熱交換部材の放熱又は吸熱を切り換えることができ、使用目的に応じて切換を行う。一方、熱電変換素子は、弾性体シール及び第２熱交換部材を介してハウジングの係止部と第１熱交換部材とに狭持されている構成のため、熱電変換素子には弾性体シールの弾性力による応力のみが掛かる。第１熱交換部材や第２熱交換部材やハウジングは、弾性の少ない固形体であるため、僅かな寸法のばらつきでも大きな力として熱電変換素子に加わるが、弾性体シールを中間に加えることによって同じばらつきでも寸法を吸収するだけでなく、熱電変換素子に安定した荷重が得られる。更に、寸法のばらつきが生じても、ばらついた分は弾性体シールにて吸収することができる。
【０００７】
熱電変換素子の狭持力が小さいと、素子が動いてしまうという不具合が生じてしまう。そこで、請求項２の発明において講じた技術的手段は、第１熱交換部材と前記第２熱交換部材との間に配設され、前記熱電変換素子の位置決めをする断熱部材を備えたことである。
【０００８】
上記構成において、熱電変換素子の狭持力が弱くても、断熱部材により熱電変換素子の位置決めができると共に、第１熱交換部材及び第２熱交換部材間での輻射による熱伝達が防止できる。
【０００９】
【発明の実施形態】
本発明に係る実施形態を図面に基づいて説明する。
【００１０】
図１は、本実施形態の熱電変換装置の断面図である。同図において、ハウジング１０には、第１熱交換部材１１がネジ１２により結合されている。この第１熱交換部材１１の上面には、熱電変換素子１３の一方の熱交換面（本実施形態では下面）１３ａが接触している。熱電変換素子１３の他方の熱交換面（本実施形態では上面）１３ｂは、第２熱交換部材１４が接触している。この第２熱交換部材１４は、そのフランジ１４ａがハウジング１０に設けられた係止部１０ａに係止されていて、結果、熱電変換素子１３とハウジング１０に設けられた係止部１０ａとにより狭持されている。更に、ハウジングの係止部１０ａには、凹部１０ｂが形成されており、そこに弾性体シール１５が嵌め込まれている。
【００１１】
尚、１６は、熱電変換素子１３を位置決めすると共に、第１及び第２熱交換部材１１、１４間の輻射による熱伝達を防止する断熱部材であり、この断熱部材１６の高さは、熱電変換素子１３よりも低く設定する。
【００１２】
上記構成の本実施形態においては、熱電変換素子１３への通電方向を切り換えるだけで、第１及び第２熱交換部材１１、１４の放熱又は吸熱を切り換えることができ、使用目的に応じて切換を行う。
【００１３】
一方、熱電変換素子１３は、弾性体シール１５及び第２熱交換部材１４を介してハウジング１０の係止部１０ａと第１熱交換部材１１とに狭持されている構成のため、熱電変換素子１３には弾性体シール１５の弾性力による応力のみが掛かるので、熱電変換素子１３の破損を防止することができる。
【００１４】
更に、寸法のばらつきが生じても、ばらついた分は弾性体シール１５にて吸収することができる。
【００１５】
更に、熱電変換素子１３の狭持力が弱くても、断熱部材１６により熱電変換素子１３の位置決めができ、第１熱交換部材１１及び第２熱交換部材１４間での輻射による熱伝達が防止できる。
【００１６】
【発明の効果】
請求項１の発明においては、熱電変換素子が、弾性体シール及び第２熱交換部材を介してハウジングの係止部と第１熱交換部材とに狭持されている構成のため、熱電変換素子には弾性体シールの弾性力による応力のみが掛かるので、熱電変換素子の破損を防止することができる。第１熱交換部材や第２熱交換部材やハウジングは、弾性の少ない固形体であるため、僅かな寸法のばらつきでも大きな力として熱電変換素子に加わるが、弾性体シールを中間に加えることによって同じばらつきでも寸法を吸収するだけでなく、熱電変換素子に安定した荷重が得られる。
【００１７】
更に、寸法のばらつきが生じても、ばらついた分は弾性体シールにて吸収することができる。
【００１８】
請求項２の発明においては、熱電変換素子の狭持力が弱くても、断熱部材により熱電変換素子の位置決めができ、第１熱交換部材及び第２熱交換部材間での輻射による熱伝達が防止できる。

[Industrial applications]
The present invention relates to a thermoelectric conversion device.
[0002]
[Prior art]
As this type of conventional technology, for example, a technology disclosed in Japanese Utility Model Application Laid-Open No. Sho 62-97467 is known. This is a screw connection in which the thermoelectric conversion element is held between the heat radiator and the heat transfer block.
[0003]
[Problems to be solved by the invention]
In the above-described conventional technology, screws are connected via spacers to prevent screws from being excessively tightened. However, according to this configuration, variations in dimensions of spacers, thermoelectric conversion elements, and heat transfer blocks cause In some cases, the tightening force of the screw is directly transmitted to the thermoelectric conversion element. As a result, the thermoelectric conversion element may be damaged.
[0004]
An object of the present invention is to provide a thermoelectric conversion device in which an excessive stress is not applied to a thermoelectric conversion element.

[Means for Solving the Problems]
In order to solve the above-mentioned technical problems, the technical measures taken in the first aspect of the present invention include a housing, a first heat exchange member coupled to the housing, and one heat exchange surface in contact with the first heat exchange member. The thermoelectric conversion element is in contact with the other heat exchange surface of the thermoelectric conversion element, and is locked to the locking portion of the housing via an elastic seal, and is sandwiched between the thermoelectric conversion element and the locking portion. A second heat exchange member held in a state , wherein the thermoelectric conversion element is sandwiched between the locking portion of the housing and the first heat exchange member via the elastic seal and the second heat exchange member. it is that the thermoelectric conversion device according to claim is.
[0006]
In the present invention having the above-described configuration, heat radiation or heat absorption of the first and second heat exchange members can be switched simply by switching the direction of energization to the thermoelectric conversion element, and the switching is performed according to the purpose of use. On the other hand, since the thermoelectric conversion element is sandwiched between the locking portion of the housing and the first heat exchange member via the elastic seal and the second heat exchange member, the thermoelectric conversion element has an elastic seal. Only the stress due to elastic force is applied. Since the first heat exchange member, the second heat exchange member, and the housing are solid bodies having low elasticity, even a small dimensional variation is applied to the thermoelectric conversion element as a large force, but the same effect is obtained by adding an elastic seal in the middle. In addition to absorbing the size even with the variation, a stable load can be obtained on the thermoelectric conversion element. Furthermore, even if the dimensional variation occurs, the variation can be absorbed by the elastic seal.
[0007]
If the holding force of the thermoelectric conversion element is small, there occurs a problem that the element moves. Therefore, a technical measure taken in the invention of claim 2 is that a heat insulating member that is disposed between the first heat exchange member and the second heat exchange member and that positions the thermoelectric conversion element is provided. is there.
[0008]
In the above configuration, even if the holding force of the thermoelectric conversion element is weak, the thermoelectric conversion element can be positioned by the heat insulating member, and the heat transfer due to radiation between the first heat exchange member and the second heat exchange member can be prevented.
