Description

発電装置Power generator
　本発明は本装置の熱源と冷却機構の間に於いて、熱電変換素子及び薄型プレートヒートデバイスを用いて発電量を増やすことを可能にする発電装置に関する。 The present invention relates to a power generation apparatus that can increase a power generation amount using a thermoelectric conversion element and a thin plate heat device between a heat source and a cooling mechanism of the present apparatus.
　従来、この種の発電装置に用いる熱電変換素子の技術の一例としては図９に示す特開２００３−２８２９７２号公開特許公報に開示されたものがある。これについて説明すれば、熱電素子は大きく分類して熱電変換素子とペルチェ素子に分けられる。熱電変換素子は、熱電変換素子の両端に温度差を与えることで両端間に熱起電力を発生するゼーベック効果を利用して熱エネルギーを直接電力に変換する素子である。熱電変換素子によれば、Ｐ型半導体とＮ型半導体の相異なる熱電変換材料を熱的に並列に置き、素子を電気的に直列に接続して外部に負荷を接続して閉回路を構成することで回路に電流が流れ、電力として取り出すことができる。
　また、ペルチェ素子は、Ｐ型半導体とＮ型半導体の相異なる熱電変換材料を熱的に並列に置き、素子を電気的に直列に接続して外部に負荷を接続して閉回路を構成し、回路に一方向に電流を流したときにＰ型半導体とＮ型半導体の接合部においては電流方向に依存して熱が放出、あるいは吸収される。この現象はペルチェ効果と呼ばれ、電流方向を変えると放熱と吸熱が逆転する。ペルチェ素子においてはこの接合部の方向をそろえて形成してあり、直流電流を流すとペルチェ素子の一方側が吸熱側すなわち低温側となり、他方側が放熱側すなわち高温側となる。多くはこの吸熱側を用いて冷却、あるいは温度制御に利用されている。上記熱電変換素子とペルチェ素子は上記ゼーベック効果を用いて発電するか、あるいは素子に給電してペルチェ効果により冷却させるかの違いで、基本的な構成はほぼ同一である。
　熱電変換素子ＡはＰ型半導体からなる柱１とＮ型半導体からなる柱２の両端に接合用の半田層３を形成し、前記柱を交互に配列する。一方、絶縁基板４の所望の位置に電極層５をメタライズ形成した後、上記整列させた柱に上下電極層５を形成した絶縁基板４で挟み込んだ状態でリフローさせ半田層３を溶解して接合させる。その後、ペルチェ素子Ａの端部の引き出し電極部６に電力導線７を接続して熱電変換素子Ａが完成する。そして、該熱電変換素子Ａの吸熱側Ａ１を図１０に示すように熱源８に例えば熱伝導グリス等の熱伝導度の高い物質（図示せず）を介して貼着して、熱源８からの熱を熱電変換素子Ａの吸熱側が吸熱し、熱電変換素子Ａの冷却側Ａ２を冷却する。
　熱電変換素子とヒートパイプを組み合わせた発電装置は特開２００１−２８２３９６号公開特許公報に開示されたものがある。ヒートパイプの一端側を熱源と接触させ、該ヒートパイプの他端に熱電変換素子の一面側を接触させ、且つ、熱電変換素子の他面側を冷却機構に接触させる方法が明記されている。しかし、この方法では、熱電変換素子を配置するための表面積が確保できず、且つ、ヒートパイプの断面形状を四角にすることで熱を輸送する部分の熱抵抗が増すため、熱電変換素子との接触面の温度が上がらず、十分な発電量が得られない。
　特開２００８−１４３４３２公開特許公報に開示されたものがある。通常のヒートパイプの断面は円形であり、また、熱電変換素子の接触面は平面であるため、ヒートパイプをつぶし、平面に成形するか、もしくはヒートパイプと熱電変換素子との間に受熱板を設けることが一般的である。しかし、この方法では、上記と同様に熱電変換素子との接触面の温度が上がらず、十分な発電量が得られない。また、ヒートパイプは曲げるために、直径が少なくとも約３倍の曲げＲが必要で、スペースが狭い場合はパイプの径を小さくする必要がある。そのため、熱の輸送量も小さく、且つ、熱電変換素子との接触面が小さくなり、十分な発電量が得られない。さらに熱電変換素子との接触面積を大きくするために、複数のヒートパイプを並列に配置する必要があるが、同じ形状で平面度を出すことが困難であり、接触面積を増やすことが難しい。
特開２００３−２８２９７２号公開特許公報 特開２００１−２８２３９６号公開特許公報 特開２００８−１４３４３２号公開特許公報 Conventionally, as an example of the technology of the thermoelectric conversion element used for this kind of power generation device, there is one disclosed in Japanese Patent Application Laid-Open No. 2003-282972 shown in FIG. Explaining this, thermoelectric elements are roughly classified into thermoelectric conversion elements and Peltier elements. A thermoelectric conversion element is an element that directly converts thermal energy into electric power by using a Seebeck effect that generates a thermoelectromotive force between both ends by giving a temperature difference to both ends of the thermoelectric conversion element. According to the thermoelectric conversion element, different thermoelectric conversion materials of a P-type semiconductor and an N-type semiconductor are placed in parallel, the elements are electrically connected in series, and an external load is connected to form a closed circuit. As a result, a current flows through the circuit and can be taken out as electric power.
In addition, the Peltier element is a closed circuit in which P-type semiconductor and N-type semiconductor different thermoelectric conversion materials are placed in parallel, the elements are electrically connected in series, and an external load is connected. When a current is passed through the circuit in one direction, heat is released or absorbed at the junction between the P-type semiconductor and the N-type semiconductor depending on the current direction. This phenomenon is called the Peltier effect. When the current direction is changed, heat dissipation and heat absorption are reversed. In the Peltier element, the direction of the joint is aligned, and when a direct current is passed, one side of the Peltier element becomes the heat absorption side, that is, the low temperature side, and the other side becomes the heat dissipation side, that is, the high temperature side. In many cases, the heat absorption side is used for cooling or temperature control. The thermoelectric conversion element and the Peltier element have almost the same basic configuration, depending on whether the Seebeck effect is used to generate power or the element is fed and cooled by the Peltier effect.
In the thermoelectric conversion element A, solder layers 3 for bonding are formed on both ends of a pillar 1 made of a P-type semiconductor and a pillar 2 made of an N-type semiconductor, and the pillars are alternately arranged. On the other hand, after the electrode layer 5 is metallized at a desired position on the insulating substrate 4, the solder layer 3 is melted and bonded by reflowing with the insulating substrate 4 having the upper and lower electrode layers 5 formed between the aligned columns. Let Thereafter, the power conducting wire 7 is connected to the lead electrode portion 6 at the end of the Peltier element A to complete the thermoelectric conversion element A. Then, the endothermic side A1 of the thermoelectric conversion element A is attached to the heat source 8 via a material having a high thermal conductivity (not shown) such as heat conduction grease as shown in FIG. The heat absorption side of the thermoelectric conversion element A absorbs heat, and the cooling side A2 of the thermoelectric conversion element A is cooled.
A power generation device in which a thermoelectric conversion element and a heat pipe are combined is disclosed in Japanese Patent Laid-Open No. 2001-282396. A method is disclosed in which one end of the heat pipe is brought into contact with a heat source, one surface of the thermoelectric conversion element is brought into contact with the other end of the heat pipe, and the other surface of the thermoelectric conversion element is brought into contact with a cooling mechanism. However, in this method, the surface area for arranging the thermoelectric conversion element cannot be secured, and the heat resistance of the portion that transports heat is increased by making the cross-sectional shape of the heat pipe square. The temperature of the contact surface does not rise, and sufficient power generation cannot be obtained.
There is one disclosed in Japanese Patent Application Laid-Open No. 2008-143432. Since the cross section of a normal heat pipe is circular and the contact surface of the thermoelectric conversion element is a flat surface, the heat pipe is crushed and formed into a flat surface, or a heat receiving plate is placed between the heat pipe and the thermoelectric conversion element. It is common to provide it. However, in this method, the temperature of the contact surface with the thermoelectric conversion element does not rise as described above, and a sufficient amount of power generation cannot be obtained. Further, in order to bend the heat pipe, a bend R having a diameter of at least about 3 times is necessary, and when the space is narrow, it is necessary to reduce the diameter of the pipe. Therefore, the amount of heat transport is small, and the contact surface with the thermoelectric conversion element is small, so that a sufficient amount of power generation cannot be obtained. Further, in order to increase the contact area with the thermoelectric conversion element, it is necessary to arrange a plurality of heat pipes in parallel. However, it is difficult to obtain flatness with the same shape, and it is difficult to increase the contact area.

　以下、本発明に係る発電装置に於ける実施の形態について添付図面に基づき詳細に説明する。
　図１は本発明に係る発電装置の実施の形態としての発電装置Ｅを示す斜視図である。
　本発明に係る発電装置Ｅに於ける実施の形態の説明に先立ち、先ず本発明に係る発電装置Ｅに適用する熱電変換素子の動作原理について図２に基づいて詳細に説明する。
　熱電変換素子Ｂは、異なる材料でつくられた２つの導体からなり、熱電変換素子間に温度差が生じた際にゼーベック効果により２つの導体に電流が流れ発電装置として動作する。熱電変換素子Ｂの基本的構成は、図２に示すように、２枚のセラミックス等の絶縁伝熱板１０ａ、１０ｂの間に、電極層１１を介してＰ型半導体素子１２及びＮ型半導体素子１３が交互に接続・配置されており、電気的には直列に、熱的には並列に接続される。絶縁伝熱板１０ｂが吸熱面になり、絶縁伝熱板１０ａが冷却面になり、リード線１４の矢印方向に電流が流れる。
　熱電変換素子Ｂは、絶縁伝熱板１０ａと１０ｂに温度差が加わると、該絶縁伝熱板１０ａと１０ｂと接触している電極１１ａと１１ｂを介して、フェルミ準位の異なる金属Ｎ型半導体１３とＰ型半導体１２との間に、正孔の移動による電界が発生し、Ｎ型半導体１３の下側に接続した下部電極１１ａからＮ型半導体１３を通過して上部電極１１ｂを通ってＰ型半導体１２の下部電極１１ａへの起電力が起こる。
　次に、本発明に係る発電装置Ｅに適用する薄型プレートヒートデバイスの一つの例について、図３及び図４に基づき詳細に説明する。
図３は薄型プレートヒートデバイス１５であってその一部を切欠した平面図、図４は薄型プレートヒートデバイス１５の内部構造を示す図であって、図３に於いてその部分拡大水平断面図である。
　薄型プレートヒートデバイス１５は大きな熱量を円滑に輸送するように設計されている。また薄型プレートヒートデバイス１５の内部はループ型蛇行細径トンネルヒートパイプ１６を内蔵しておりこのループ型蛇行細径トンネルヒートパイプ１６の内部に封入した図４に示すように作動液１６ａが還流管路１６ｂにＤ方向に流送する。そしてこの作動液１６ａの内圧に対して該プレートヒートデバイス１５のループ型蛇行細径トンネルヒートパイプ１６が十分な強度を有する必要がある。このような各種の条件を満足する薄型プレートヒートデバイス１５は薄型プレート１５Ａ内に前述したループ型蛇行細径トンネルヒートパイプ１６を備えてある。
　そして、こような単位対のループ型蛇行細径トンネルヒートパイプ１６の群は相互に連結連通されて、平面状に構成されて一体化されてある。このように一体化されたループ型蛇行細径トンネルヒートパイプ１６の群は、一括して密閉封止され且つ真空脱気された上で所定の二相凝縮性作動液の所定量が封入されてヒートパイプ化されて、構成されている。図４において１５Ｂは受熱部の位置を示し、１５Ｃは放熱部の位置を示す。
　次に、本発明に係る発電装置Ｅに適用する薄型プレートヒートデバイスの他の例について図５に基づき詳細に説明する。１７は薄型プレートヒートデバイスであって、熱伝導性の良好な金属からなる単位薄板１８及び平薄板１９の溶接積層体でなる。単位薄板１８の溶接面には積層に先立って予め一連の長尺蛇行細溝１８ａが形成されてある。該長尺蛇行細溝１８ａの形成は切削、放電加工、プレス成形等何れの手段によってなされたものであっても良い。長尺蛇行細溝１８ａは積層により密閉蛇行細径として構成され、この密閉蛇行細径に所定の作動液１６ａの所定量が封入されて蛇行細径トンネルヒートパイプ１６として構成されてある。
　図５は長尺蛇行細溝１８ａが形成されてある単位薄板１８と細溝が形成されていない単なる平薄板１９とが積層されてある例である。
単位薄板１８に内蔵したループ型蛇行細径トンネルヒートパイプ１６はターン部の曲率半径を極限に至るまで小さくできる。そして細溝幅に溝山の幅１ｍｍ程度を加算しただけのピッチで高密度に配接することが可能となり、多数ターンの細管ヒートパイプを内蔵することが出来る。従って高性能で且つ厚さの薄いプレート形ヒートパイプを構成することが可能になる。一例としては外径３ｍｍ内径２ｍｍの蛇行細管ヒートパイプに替えて細管ヒートパイプを内蔵する場合は径２ｍｍの細管をピッチ３ｍｍで内蔵することが可能であり、１００ｍｍ幅の中に３３本を配設した厚さ５ｍｍのプレート形ヒートパイプを構成することが可能となる。そして作動液１６ａの循環及び振動に際して無駄な抵抗の発生が少ないことが利点である。
　薄型プレートヒートデバイス１５、１７に内蔵しているループ型蛇行細径トンネルヒートパイプ１６や長尺蛇行細溝１８ａは何れもどのような設置条件や配置形態又は保持姿勢でも作動液１６ａの流送が活発に作動する特性があることを共通の利点としている。従って本発明ではこれらのループ型蛇行細径トンネルヒートパイプ１６等を内蔵する薄型プレートヒートデバイス１５、１７は、従来の熱電変換素子Ａのみでなる熱電素子が具有する問題点をすべて解決するものである。加えてＩＴ業界等に於ける機器の小型化、軽量化及び高密度集積化により、薄型プレートヒートデバイス１５、１７に内蔵されるループ型蛇行細径トンネルヒートパイプ１６や長尺蛇行細溝１８ａはその重量と雖も無視出来なくなりつつあり、一層の小型軽量化が要求され、本発明はこれに対処できる。
　次に本発明に係る発電装置Ｅに於ける構成について、図１に基づいて詳細に説明する。図１は本発明に係る発電装置Ｅの一例を示す斜視図であって、理解のために後述する熱源及び冷却機構を配備した構成について図示している。Ｂは各前記熱電変換素子であり、２０は薄型Ｌ字状プレートヒートデバイスである。薄型Ｌ字状プレートヒートデバイス２０は金属平板をＬ字状に曲げ加工してあり、図１に示すように薄型Ｌ字状プレートヒートデバイス２０の一方側に複数の熱電変換素子Ｂを貼着する。ここでは４個の熱電変換素子Ｂを貼着しており、その立設部位に３個の、底辺部位に１個又は複数個の熱電変換素子Ｂを貼着する。全ての熱電変換素子Ｂを前記薄型Ｌ字状プレートヒートデバイス２０に貼着するとき複数の熱電変換素子Ｂに於ける４個の全ての貼着面つまり図２に示す絶縁伝熱版１０ｂの側が例えば吸熱面側になるように配設する。
　尚、本発明に係る発電装置Ｅの取り付け位置や設計条件、配置形態又は保持姿勢等はその使用目的により複数の熱電変換素子Ｂの貼着面を吸熱面側に限定せず冷却面側にしてもよい。この例では各熱電変換素子Ｂの吸熱面側を貼着面とする。具体的には各熱電変換素子Ｂの一方の絶縁伝熱板（図２に示す絶縁伝熱板１０ａに相当）を前記薄型Ｌ字状プレートヒートデバイス２０の金属平板（図３、図５に示す薄型プレート１５Ａ、平薄板１９に相当）に貼着する。各熱電変換素子Ｂと薄型Ｌ字状プレートヒートデバイス２０の貼着面は微小な隙間（図示せず）が存在するが、その隙間に熱伝導率の良好な粘着物例えば熱伝導グリス２１や接着剤を塗布・充填する。このとき、該隙間に充填した熱伝導グリス２１に気泡を封止しないように、また熱伝導グリス２１の厚さが厚くならないように熱電変換素子Ｂと薄型Ｌ字状プレートヒートデバイス２０を互いに摺り合わせて圧接する。尚、熱伝導グリス２１は酸化亜鉛等の金属微粉末を混練したシリコーングリス等や銀ペイントのような熱伝導率が大きく良好な熱伝導を得る上で塗布剤として有効なものを採用する。
尚、本発明は上記薄型Ｌ字状プレートヒートデバイス２０をこの形状に限定せず、本発明に係る発電装置Ｅの設置場所や設計条件等により平板状でなる矩形や正方形等各種の形状であっても差支えない。
　２２は本発明に係る発電装置Ｅを設置することによって吸熱する熱源である。図１に於いて本発明に係る発電装置Ｅと熱源２２は離間して図示しているが、実施形態に於いては熱源２２を薄型Ｌ字状プレートヒートデバイス２０の他方側、つまり金属平板（図３、図５に示す薄型プレート１５Ａ、平薄板１９に相当）に密着させる。その際は前記熱伝導グリス２１等を介在させて密着させ、熱源２２と薄型Ｌ字状プレートヒートデバイス２０を熱的に一体化する。
　２３は本発明に係る発電装置Ｅによって熱源２２から吸収した熱を熱電変換素子の発電を促すための冷却機構である。図１に於いて本発明に係る発電装置Ｅと冷却機構２３は離間して図示しているが、実施形態に於いては立設・配設された３個の各熱電変換素子Ｂ及び底辺部位に配設された１個の熱電変換素子Ｂの他方の絶縁伝熱板（図２に示す絶縁伝熱板１０ｂに相当）に密着させる。その際は前記熱伝導グリス２１等を介在させて密着させ、冷却機構２３と前記熱電変換素子Ｂを熱的に一体化する。
　次に本発明に係る発電装置Ｅの実施の形態に於ける動作等を説明する。図１に於いて
熱源２２から熱が薄型Ｌ字状プレートヒートデバイス２０の他方側、つまり薄型プレート１５Ａ、単位薄板１８（図３、図５に示す）に熱伝導する。そこで、薄型Ｌ字状プレートヒートデバイス２０のループ型蛇行細径トンネルヒートパイプ１６や長尺蛇行細溝１８ａに封入された作動液１６ａが潜熱を摂取して蒸発する。その蒸気は該薄型Ｌ字状プレートヒートデバイス２０のループ型蛇行細径トンネルヒートパイプ１６や長尺蛇行細溝１８ａを介して蒸発部（図示せず）から送出される。一方、液相の作動液１６ａは蒸発部（図示せず）の内周面に供給されると共に潜熱として熱を輸送することができる。この輸送速度が高速であって、効率よく輸送される。
　前記ループ型蛇行細径トンネルヒートパイプ１６や長尺蛇行細溝１８ａは、蛇行パターン数が多い程輸送性能を向上させる。トップヒートモードに於ける性能がボトムヒートモードのときの性能と大差なく良好に作動させるためには１００（ｍｍ）幅の中に３０ターン以上が必要とされる。
　而して前記薄型Ｌ字状プレートヒートデバイス２０の一方側、つまり金属平板（図３、図５に示す薄型プレート１５Ａ、平薄板１９に相当）に高速かつ効率的に輸送された熱は４個の熱電変換素子Ｂの絶縁伝熱板１０ａに熱的に接続され、一方、冷却機構２３は熱電変換素子Ｂの絶縁伝熱板１０ｂへと熱的に接続される。熱電変換素子Ｂの基本的構成は、２枚のセラミックス等の絶縁伝熱板１０ａ、１０ｂの間に、電極層１１を介してＰ型半導体素子１２及びＮ型半導体素子１３が交互に接続・配置されており、電気的には直列に、熱的には並列に接続される。熱電変換素子Ｂは、絶縁伝熱板１０ａと１０ｂに温度差が加わると、該絶縁伝熱板１０ａと１０ｂと接触している電極１１ａと１１ｂを介して、フェルミ準位の異なる金属Ｎ型半導体１３とＰ型半導体１２との間に、正孔の移動による電界が発生し、Ｎ型半導体１３の下側に接続した下部電極１１ａからＮ型半導体１３を通過して上部電極１１ｂを通ってＰ型半導体１２の下部電極１１ａへの起電力が起こる。
すなわち、本発明に係る発電装置Ｅは各種の自動車機器や建築設備機器に応用できる。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a power generator according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing a power generation device E as an embodiment of the power generation device according to the present invention.
Prior to the description of the embodiment of the power generation apparatus E according to the present invention, the operation principle of the thermoelectric conversion element applied to the power generation apparatus E according to the present invention will be described in detail with reference to FIG.
The thermoelectric conversion element B is composed of two conductors made of different materials, and when a temperature difference occurs between the thermoelectric conversion elements, current flows through the two conductors due to the Seebeck effect and operates as a power generator. As shown in FIG. 2, the basic configuration of the thermoelectric conversion element B is that a P-type semiconductor element 12 and an N-type semiconductor element are interposed between two insulating heat transfer plates 10a and 10b made of ceramics or the like via an electrode layer 11. 13 are alternately connected and arranged, and are electrically connected in series and thermally connected in parallel. The insulated heat transfer plate 10 b becomes a heat absorption surface, the insulated heat transfer plate 10 a becomes a cooling surface, and a current flows in the direction of the arrow of the lead wire 14.
When a temperature difference is applied to the insulating heat transfer plates 10a and 10b, the thermoelectric conversion element B is a metal N-type semiconductor having different Fermi levels via the electrodes 11a and 11b in contact with the insulating heat transfer plates 10a and 10b. An electric field due to the movement of holes is generated between the P-type semiconductor 12 and the P-type semiconductor 12, and passes through the N-type semiconductor 13 from the lower electrode 11a connected to the lower side of the N-type semiconductor 13 and passes through the upper electrode 11b. An electromotive force is generated in the lower electrode 11a of the type semiconductor 12.
Next, one example of a thin plate heat device applied to the power generation apparatus E according to the present invention will be described in detail based on FIG. 3 and FIG.
FIG. 3 is a plan view of the thin plate heat device 15 partially cut away, and FIG. 4 is a diagram showing the internal structure of the thin plate heat device 15, which is a partially enlarged horizontal sectional view in FIG. is there.
The thin plate heat device 15 is designed to smoothly transport a large amount of heat. The thin plate heat device 15 contains a loop-type meandering small-diameter tunnel heat pipe 16. As shown in FIG. Flow in the direction D to the path 16b. The loop meandering small diameter tunnel heat pipe 16 of the plate heat device 15 needs to have sufficient strength against the internal pressure of the hydraulic fluid 16a. The thin plate heat device 15 satisfying such various conditions is provided with the loop-shaped meandering thin tunnel heat pipe 16 described above in the thin plate 15A.
A group of such unit pairs of loop-shaped meandering small-diameter tunnel heat pipes 16 are connected and communicated with each other, and are configured to be planar and integrated. The group of loop-type meandering small diameter tunnel heat pipes 16 integrated in this way is hermetically sealed together and vacuum degassed, and then a predetermined amount of a predetermined two-phase condensable hydraulic fluid is enclosed. It is made up of heat pipes. In FIG. 4, 15B indicates the position of the heat receiving portion, and 15C indicates the position of the heat radiating portion.
Next, another example of the thin plate heat device applied to the power generation apparatus E according to the present invention will be described in detail with reference to FIG. Reference numeral 17 denotes a thin plate heat device, which is a welded laminate of unit thin plates 18 and flat thin plates 19 made of a metal having good thermal conductivity. Prior to lamination, a series of long meandering narrow grooves 18a are formed on the welding surface of the unit thin plate 18 in advance. The long meandering narrow groove 18a may be formed by any means such as cutting, electric discharge machining, or press molding. The long meandering narrow groove 18a is configured as a closed meandering narrow diameter by stacking, and a predetermined amount of a predetermined working fluid 16a is enclosed in the tight meandering narrow diameter, and the meandering narrow diameter tunnel heat pipe 16 is configured.
FIG. 5 shows an example in which unit thin plates 18 in which long meandering narrow grooves 18a are formed and simple flat thin plates 19 in which no narrow grooves are formed are laminated.
The loop-shaped meandering thin tunnel heat pipe 16 built in the unit thin plate 18 can reduce the radius of curvature of the turn portion to the limit. And it becomes possible to arrange with high density at a pitch that is just the sum of the groove width of about 1 mm to the width of the narrow groove, and it is possible to incorporate a multi-turn thin pipe heat pipe. Therefore, it is possible to construct a plate-type heat pipe with high performance and a small thickness. As an example, when a thin tube heat pipe is incorporated instead of a meandering thin tube heat pipe with an outer diameter of 3 mm and an inner diameter of 2 mm, it is possible to incorporate a 2 mm diameter narrow tube with a pitch of 3 mm, and 33 tubes are arranged in a width of 100 mm. It is possible to construct a plate-type heat pipe having a thickness of 5 mm. The advantage is that less resistance is generated when the hydraulic fluid 16a is circulated and vibrated.
The loop type meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a incorporated in the thin plate heat devices 15 and 17 can flow the hydraulic fluid 16a in any installation condition, arrangement form or holding posture. The common advantage is that it has active characteristics. Therefore, in the present invention, the thin plate heat devices 15 and 17 incorporating the loop type meandering thin tunnel heat pipe 16 and the like solve all the problems of the conventional thermoelectric element composed only of the thermoelectric conversion element A. is there. In addition, due to miniaturization, weight reduction, and high density integration of equipment in the IT industry etc., the loop type meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a incorporated in the thin plate heat devices 15, 17 The weight and wrinkle are becoming ignorable, and further reduction in size and weight is required, and the present invention can cope with this.
Next, the configuration of the power generator E according to the present invention will be described in detail with reference to FIG. FIG. 1 is a perspective view showing an example of a power generation apparatus E according to the present invention, and illustrates a configuration in which a heat source and a cooling mechanism described later are provided for the sake of understanding. B is each thermoelectric conversion element, and 20 is a thin L-shaped plate heat device. The thin L-shaped plate heat device 20 is formed by bending a metal flat plate into an L shape, and a plurality of thermoelectric conversion elements B are attached to one side of the thin L-shaped plate heat device 20 as shown in FIG. . Here, four thermoelectric conversion elements B are attached, and three or more thermoelectric conversion elements B are attached to the standing part and three base parts. When all the thermoelectric conversion elements B are bonded to the thin L-shaped plate heat device 20, all four bonding surfaces in the plurality of thermoelectric conversion elements B, that is, the insulating heat transfer plate 10b side shown in FIG. For example, it arrange | positions so that it may become an endothermic surface side.
Note that the mounting position, design conditions, arrangement form, holding posture, etc. of the power generator E according to the present invention are not limited to the heat absorption surface side but the cooling surface side depending on the purpose of use. Also good. In this example, the endothermic surface side of each thermoelectric conversion element B is used as the sticking surface. Specifically, one insulating heat transfer plate (corresponding to the insulating heat transfer plate 10a shown in FIG. 2) of each thermoelectric conversion element B is used as a metal flat plate of the thin L-shaped plate heat device 20 (shown in FIGS. 3 and 5). A thin plate 15A and a flat thin plate 19). There are minute gaps (not shown) on the bonding surfaces of each thermoelectric conversion element B and the thin L-shaped plate heat device 20, and an adhesive having a good thermal conductivity, such as heat conduction grease 21 or adhesion, is present in the gap. Apply and fill the agent. At this time, the thermoelectric conversion element B and the thin L-shaped plate heat device 20 are slid against each other so as not to seal bubbles in the heat conductive grease 21 filled in the gap and so that the thickness of the heat conductive grease 21 does not increase. Weld together. As the heat conductive grease 21, a silicone grease or the like kneaded with metal fine powder such as zinc oxide, or silver paint, which has a high heat conductivity and is effective as a coating agent for obtaining good heat conduction, is adopted.
In the present invention, the thin L-shaped plate heat device 20 is not limited to this shape, and may have various shapes such as a rectangular shape and a square shape depending on the installation location and design conditions of the power generation apparatus E according to the present invention. It doesn't matter.
Reference numeral 22 denotes a heat source that absorbs heat by installing the power generation device E according to the present invention. In FIG. 1, the power generation apparatus E and the heat source 22 according to the present invention are illustrated separately from each other, but in the embodiment, the heat source 22 is connected to the other side of the thin L-shaped plate heat device 20, that is, a metal flat plate ( The thin plate 15A and the flat thin plate 19 shown in FIGS. At that time, the heat conduction grease 21 and the like are interposed and adhered, and the heat source 22 and the thin L-shaped plate heat device 20 are thermally integrated.
Reference numeral 23 denotes a cooling mechanism for encouraging the power generation of the thermoelectric conversion element by the heat absorbed from the heat source 22 by the power generation apparatus E according to the present invention. In FIG. 1, the power generation device E and the cooling mechanism 23 according to the present invention are shown apart from each other, but in the embodiment, each of the three thermoelectric conversion elements B and the bottom portion that are erected and arranged are arranged. Are attached to the other insulating heat transfer plate (corresponding to the insulating heat transfer plate 10b shown in FIG. 2) of one thermoelectric conversion element B. At that time, the heat conduction grease 21 or the like is interposed between the cooling mechanism 23 and the thermoelectric conversion element B so as to be thermally integrated.
Next, operation | movement etc. in embodiment of the electric power generating apparatus E which concern on this invention are demonstrated. In FIG. 1, heat is conducted from the heat source 22 to the other side of the thin L-shaped plate heat device 20, that is, the thin plate 15A and the unit thin plate 18 (shown in FIGS. 3 and 5). Therefore, the working fluid 16a enclosed in the loop-shaped meandering narrow tunnel heat pipe 16 and the long meandering narrow groove 18a of the thin L-shaped plate heat device 20 ingests latent heat and evaporates. The steam is sent out from an evaporation section (not shown) through the loop-shaped meandering thin tunnel heat pipe 16 and the long meandering narrow groove 18a of the thin L-shaped plate heat device 20. On the other hand, the liquid-phase working fluid 16a is supplied to the inner peripheral surface of the evaporation section (not shown) and can transport heat as latent heat. This transportation speed is high, and it is transported efficiently.
The loop type meandering tunnel heat pipe 16 and the long meandering narrow groove 18a improve the transport performance as the number of meandering patterns increases. In order for the performance in the top heat mode to operate satisfactorily without much difference from the performance in the bottom heat mode, 30 turns or more are required in a width of 100 (mm).
Thus, four heats are transported at high speed and efficiently to one side of the thin L-shaped plate heat device 20, that is, a metal flat plate (corresponding to the thin plate 15A and the flat thin plate 19 shown in FIGS. 3 and 5). The cooling mechanism 23 is thermally connected to the insulated heat transfer plate 10b of the thermoelectric conversion element B. On the other hand, the cooling mechanism 23 is thermally connected to the insulated heat transfer plate 10b of the thermoelectric conversion element B. The basic configuration of the thermoelectric conversion element B is that P-type semiconductor elements 12 and N-type semiconductor elements 13 are alternately connected and arranged between two insulating heat transfer plates 10a, 10b made of ceramics or the like via electrode layers 11. It is electrically connected in series and thermally connected in parallel. When a temperature difference is applied to the insulating heat transfer plates 10a and 10b, the thermoelectric conversion element B is a metal N-type semiconductor having different Fermi levels via the electrodes 11a and 11b in contact with the insulating heat transfer plates 10a and 10b. An electric field due to the movement of holes is generated between the P-type semiconductor 12 and the P-type semiconductor 12, and passes through the N-type semiconductor 13 from the lower electrode 11a connected to the lower side of the N-type semiconductor 13 and passes through the upper electrode 11b. An electromotive force is generated in the lower electrode 11a of the type semiconductor 12.
That is, the power generation apparatus E according to the present invention can be applied to various types of automobile equipment and building equipment.
