しかしながら、従来の発明にあっては、排気ガス通路部、熱電変換部、冷却流通媒体通路部をユニット化して個々に連結して構成しているため、部品点数及び組み付け工数が増えてコストアップになる上、これらを積層すると排気ガス通路部（フィン）が隣接した状態となり、コア部の単位面積当たりに設置できる熱電変換部の数が少なくなって発電効率が悪いという問題点があった。 However, in the conventional invention, the exhaust gas passage portion, the thermoelectric conversion portion, and the cooling flow medium passage portion are unitized and connected individually, which increases the number of parts and the number of assembling steps, thereby increasing the cost. In addition, when these layers are stacked, the exhaust gas passage portions (fins) are adjacent to each other, and the number of thermoelectric conversion portions that can be installed per unit area of the core portion is reduced, resulting in poor power generation efficiency.
さらに、隣接する排気ガス通路部（フィン）同士はろう付けにより接合できないため、これら両者間には所定のクリアランスが必要となり、コア部の大型化を招いてしまう。 Furthermore, since the adjacent exhaust gas passage portions (fins) cannot be joined together by brazing, a predetermined clearance is required between them, leading to an increase in the size of the core portion.
本発明は上記課題を解決するためになされたものであって、その目的とするところは、発電効率の向上とコア部のコンパクト化を達成できる発電装置を提供することである。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a power generation device capable of achieving improvement in power generation efficiency and downsizing of the core portion.

It has a core part formed by laminating the exhaust gas passage part and the cooling flow medium passage part as a common member of adjacent thermoelectric conversion parts.

このように構成された発電装置１を製造する際は、先ず、熱電変換部６の熱電素子部１０、接続コネクタ１６を除くコア部４の各構成部材を仮組みして図外の加熱炉に搬送した後、熱処理することにより一体的に形成する。
Next, the operation will be described.
When manufacturing the power generation device 1 configured as described above, first, the respective constituent members of the core portion 4 excluding the thermoelectric element portion 10 and the connection connector 16 of the thermoelectric conversion portion 6 are temporarily assembled into a heating furnace (not shown). After carrying, it forms integrally by heat-processing.
次に、各ケース９の一方側端部（図３中右側）の開口からそれぞれ対応する熱電素子部１０の結線端子部１０ｃを挿入して他方側端部（図３中左側）の開口から突出させた状態とした後、接続コネクタ部１６を装着して結線端子部１０ｃと接続する。

It is fixed by welding outside the figure.
このように構成された発電装置１は、図８に示すＥＧＲ装置２０の排気系経路内に設置される。
ＥＧＲ装置２０は、ディーゼル機関であるエンジン２１と、ターボチャージャー２２と、インタークーラ２３と、発電装置１と、ラジエータ２４と、ＤＰＦ装置２５が備えられている。
The power generator 1 configured as described above is installed in the exhaust system path of the EGR device 20 shown in FIG.
The EGR device 20 includes an engine 21 that is a diesel engine, a turbocharger 22, an intercooler 23, a power generation device 1, a radiator 24, and a DPF device 25.
また、図示を省略するエアクリーナから導いた吸気を、吸気管２６ａを介してターボチャージャー２２のコンプレッサ２２ａへ導入して加圧し、さらに、接続管２６ｂを介してインタークーラ２３に導入して冷却した後、インテークマニホールド２６ｃを介してエンジン２１の各気筒（図示せず）に分配するようにしている。 Also, after intake air introduced from an air cleaner (not shown) is introduced into the compressor 22a of the turbocharger 22 through the intake pipe 26a and pressurized, and further introduced into the intercooler 23 through the connection pipe 26b and cooled. The engine 21 is distributed to each cylinder (not shown) of the engine 21 via the intake manifold 26c.
また、エンジン２１から排出された排気ガスを、エキゾーストマニホールド２６ｄを介してターボチャージャー２２のタービン２２ｂへ導入して駆動した後、ＤＰＦ装置２５を介して車外へ排出するようにしている。 Further, exhaust gas discharged from the engine 21 is introduced into the turbine 22b of the turbocharger 22 via the exhaust manifold 26d and driven, and then discharged outside the vehicle via the DPF device 25.
そして、発電装置１の接続管２のフランジ部２ａは、エキゾーストマニホールド２６ｄに接続された接続管２６ｅに接続される一方、接続管３のフランジ部３ａは、インテークマニホールド２６ｃに接続された接続管２６ｆに接続されている。 The flange portion 2a of the connection pipe 2 of the power generator 1 is connected to the connection pipe 26e connected to the exhaust manifold 26d, while the flange portion 3a of the connection pipe 3 is connected to the intake manifold 26c. It is connected to the.
一方、発電装置１の入出力ポートP1,P2は、エンジン２１とラジエータ２４との間で、これらエンジン２１、ラジエータ２４、発電装置１を環状に繋ぐ接続管26g,26hと接続されている。 On the other hand, the input / output ports P1 and P2 of the power generator 1 are connected between the engine 21 and the radiator 24 with connection pipes 26g and 26h that connect the engine 21, the radiator 24, and the power generator 1 in an annular shape.
従って、発電装置１のコア部４は、接続管２６ｅから接続管２を介してエキゾーストマニホールド２６ｄの高温な排気ガスの一部を導入し、接続管３を介して接続管２６ｆへ排出するようになっている。
また、接続管２６ｇから入出力ポートＰ１を介してラジエータ６で冷却された低温な冷却流通媒体を導入し、入出力ポートＰ２を介して接続管２６ｈへ排出するようになっている。
Therefore, the core portion 4 of the power generator 1 introduces a part of the hot exhaust gas of the exhaust manifold 26d from the connection pipe 26e via the connection pipe 2 and discharges it to the connection pipe 26f via the connection pipe 3. It has become.
Further, a low-temperature cooling flow medium cooled by the radiator 6 is introduced from the connection pipe 26g via the input / output port P1, and is discharged to the connection pipe 26h via the input / output port P2.
この際、コア部４に導入された排気ガスは、各排気ガス通路部５を通過し、熱電素子部１０の一方側を高温化させる一方、コア部４に導入された冷却流通媒体（図３の一点鎖線矢印で図示）は、入出力ポートＰ１から連通路Ｒ１に流入した後、各冷却流通媒体通路７ｅを流通して入出力ポートＰ２に流入する間に熱電素子部１０の他方側を低温化させることにより、熱電素子部１０がゼーベック作用を得て発電し、発電装置として機能する。 At this time, the exhaust gas introduced into the core portion 4 passes through each exhaust gas passage portion 5 to raise the temperature of one side of the thermoelectric element portion 10, while the cooling flow medium introduced into the core portion 4 (FIG. 3). (Indicated by a one-dot chain line arrow) flows from the input / output port P1 to the communication path R1, and then flows through the respective cooling flow medium passages 7e and flows into the input / output port P2, while the other side of the thermoelectric element section 10 is kept at a low temperature. As a result, the thermoelectric element unit 10 obtains Seebeck action to generate electric power and functions as a power generation device.
なお、上記得られた電力は接続コネクタ１６を介して図外のバッテリに充電される、または電子部品へ送電されるようになっている。 The obtained electric power is charged in a battery (not shown) via the connector 16 or transmitted to an electronic component.
この際、１つの排気ガス通路部５（冷却流通媒体通路部７）が隣り合う熱電変換部６のゼーベック作用に必要な共用部材として機能し、好適となる。
また、コア部４は接続管2,3を流通する排気ガス（図１、２の破線矢印で図示）の流れに対して傾斜した状態で配置されるため、高速・高温な排気ガスをコア部４に十分に当てることができると共に、発電装置１の形状を小さくできる。
At this time, one exhaust gas passage portion 5 (cooling flow medium passage portion 7) functions as a common member necessary for the Seebeck action of the adjacent thermoelectric conversion portions 6 and is suitable.
In addition, since the core part 4 is disposed in an inclined state with respect to the flow of the exhaust gas (shown by broken arrows in FIGS. 1 and 2) flowing through the connecting pipes 2 and 3, high-speed and high-temperature exhaust gas is supplied 4 and the shape of the power generator 1 can be reduced.
また、コア部４の各排気ガス通路部５を通過する排気ガスは、上述した冷却流通媒体と熱交換して冷却され、これによって発電装置１はＥＧＲクーラとして機能する。 Further, the exhaust gas that passes through each exhaust gas passage portion 5 of the core portion 4 is cooled by exchanging heat with the above-described cooling flow medium, whereby the power generator 1 functions as an EGR cooler.
ここで、従来の発明にあっては、排気ガス通路部、熱電変換部、冷却流通媒体通路部をユニット化して個々に連結して構成しているため、部品点数及び組み付け工数が増えてコストアップになる上、これらを積層すると排気ガス通路部（フィン５ａ）が隣接した状態となり、コア部の単位面積当たりに設置できる熱電変換部の数が少なくなって発電効率が悪いという問題点があった。 Here, in the conventional invention, the exhaust gas passage portion, the thermoelectric conversion portion, and the cooling flow medium passage portion are united and individually connected, so the number of parts and assembly man-hours increase and the cost increases. In addition, when these are stacked, the exhaust gas passage portions (fins 5a) are adjacent to each other, and the number of thermoelectric conversion portions that can be installed per unit area of the core portion is reduced, resulting in poor power generation efficiency. .
これに対し、本実施例１では、前述したように、全ての熱電変換部６の一方側に排気ガス通路部５が配置される一方、他方側に冷却流通媒体通路部７が隣接した状態で一体的に積層されるため、コア部４の単位面積当たりに配置できる熱電変換部６の数を多くできる。 In contrast, in the first embodiment, as described above, the exhaust gas passage portion 5 is disposed on one side of all the thermoelectric conversion portions 6, while the cooling flow medium passage portion 7 is adjacent to the other side. Since they are laminated integrally, the number of thermoelectric conversion parts 6 that can be arranged per unit area of the core part 4 can be increased.
従って、従来の発明に比べて小さなコアサイズで同等の発電性能を発揮でき、コア部４をコンパクト化できる。あるいは、従来の発明と同等のコアサイズで発電性能の向上を実現できる。
さらに、部品点数及び組み付け工数を削減してコストダウンを図れる。
Therefore, it is possible to exhibit the same power generation performance with a small core size compared to the conventional invention, and the core portion 4 can be made compact. Alternatively, the power generation performance can be improved with a core size equivalent to that of the conventional invention.
Furthermore, the number of parts and assembly man-hours can be reduced to reduce costs.
次に、効果を説明する。
以上、説明したように、本実施例１の発電装置１にあっては、排気系経路内に設置され、熱電変換部６の一方側に排気ガス通路部５を配置する一方、他方側に冷却流通媒体通路部７を配置した発電装置において、排気ガス通路部５及び冷却流通媒体通路部７を隣接する熱電変換部同士６の共用部材として積層して成るコア部４を備えるため、発電効率の向上とコア部４のコンパクト化を達成できる。
Next, the effect will be described.
As described above, in the power generation apparatus 1 according to the first embodiment, the exhaust gas passage unit 5 is disposed in one side of the thermoelectric conversion unit 6 while being cooled in the other side. In the power generation device in which the circulation medium passage portion 7 is disposed, the exhaust gas passage portion 5 and the cooling circulation medium passage portion 7 are provided with the core portion 4 that is laminated as a common member of the adjacent thermoelectric conversion portions 6. Improvement and downsizing of the core part 4 can be achieved.
また、コア部４を、排気系経路の排気ガスの流れに対して傾斜させた状態で配置したため、高速・高温な排気ガスをコア部４に十分に当てることができ、発電性能を向上できると共に、発電装置１の形状を小さくできる。 In addition, since the core part 4 is disposed in a state inclined with respect to the flow of exhaust gas in the exhaust system path, high-speed and high-temperature exhaust gas can be sufficiently applied to the core part 4 and power generation performance can be improved. The shape of the power generator 1 can be reduced.
また、コア部４の最外端に排気ガス通路部５を配置したため、排気ガスが当たるコア部４の面積を広くでき、発電性能を向上できる。 Further, since the exhaust gas passage portion 5 is disposed at the outermost end of the core portion 4, the area of the core portion 4 that the exhaust gas hits can be increased, and the power generation performance can be improved.
