Description

本発明は、小型のダイレクトメタノール燃料電池等に流通する流体のような腐蝕性流体を冷却する熱交換器に関する。   The present invention relates to a heat exchanger for cooling a corrosive fluid such as a fluid flowing in a small direct methanol fuel cell or the like.

パソコン等の小型電子機器用の燃料電池として、小型のダイレクトメタノール燃料電池が注目されている。
この燃料電池は、アノード回路の排出燃料を回収して再利用するため、回収した高温の燃料を冷却する熱交換器を必要とする。このアノード回路から排出される燃料は、蟻酸等の腐蝕性の高い物質が含まれているため、熱交換器には耐腐蝕性が要求される。
さらに燃料電池そのものが小型軽量であるため、それに用いられる熱交換器自体も小型軽量で且つ、量産性の高いものが求められている。 As a fuel cell for a small electronic device such as a personal computer, a small direct methanol fuel cell has attracted attention.
This fuel cell requires a heat exchanger for cooling the recovered high-temperature fuel in order to recover and reuse the fuel discharged from the anode circuit. Since the fuel discharged from the anode circuit contains highly corrosive substances such as formic acid, the heat exchanger is required to have corrosion resistance.
Furthermore, since the fuel cell itself is small and lightweight, the heat exchanger itself used for it is also small and light and has high mass productivity.

このような腐蝕性の高い流体を流通させる熱交換器を従来の金属材で造ると、その金属を腐蝕させ、その金属イオンを流体中に溶出し、燃料電池システムの電解質膜の破損や燃料電池の電圧降下を引き起こすことになる。   When a heat exchanger that circulates such highly corrosive fluid is made of a conventional metal material, the metal is corroded and the metal ions are eluted into the fluid, causing damage to the electrolyte membrane of the fuel cell system or fuel cell Will cause a voltage drop.

そこで、その腐食性流体に対して、下記特許文献に記載されている樹脂製熱交換器を用いることが考えられる。これはシェル＆チューブ型の熱交換器であり、腐蝕性流体が流通する多数のチューブは、樹脂材から形成されている。そして、その樹脂製チューブをヘッダに接続するために継手を用いるものである。   Therefore, it is conceivable to use a resin heat exchanger described in the following patent document for the corrosive fluid. This is a shell and tube type heat exchanger, and a large number of tubes through which a corrosive fluid flows are formed of a resin material. A joint is used to connect the resin tube to the header.

次に、図面に基づいて本発明の実施の形態を説明する。
図１は本発明の第１の実施の形態を示し、（Ａ）は正面図、（Ｂ）は（Ａ）のＢ−Ｂ矢視断面図、（Ｃ）は（Ｂ）のＣ−Ｃ矢視断面図、（Ｄ）は同熱交換器の分解斜視図である。この熱交換器は、射出成形による樹脂製の本体１と蓋体２と、本体１の平面に接着剤等により接合される金属製のフィン11とを有する。
本体１は図１（Ｃ）（Ｄ）に示す如く、全体が偏平な箱状に形成され、図において、上下一対の対向する一方の辺と他方の辺とから交互に仕切部５が上下方向に一体に延在する。その仕切部５の長さは、両辺の対向長さよりも短く形成され、それによって内部に蛇行状の流路３が形成される。そしてその流路３の一端および他端に出入口４が設けられ、そこにパイプ12が外側に突出する。そして本体１の一方側平面は図１（Ｄ）の如く開放され、その開口に整合する蓋体２が接着剤等により、そこに接合される。 Next, embodiments of the present invention will be described with reference to the drawings.
1A and 1B show a first embodiment of the present invention, in which FIG. 1A is a front view, FIG. 1B is a cross-sectional view taken along line BB in FIG. 1A, and FIG. A sectional view, (D) is an exploded perspective view of the heat exchanger. This heat exchanger has a resin-made main body 1 and lid 2 by injection molding, and metal fins 11 bonded to the plane of the main body 1 by an adhesive or the like.
As shown in FIGS. 1C and 1D, the main body 1 is formed in a flat box shape as a whole, and in the figure, the partitioning portions 5 are alternately arranged in a vertical direction from a pair of upper and lower opposing sides and the other side. It extends integrally. The length of the partition 5 is shorter than the opposing length of both sides, thereby forming a meandering flow path 3 inside. And the entrance / exit 4 is provided in the one end and the other end of the flow path 3, and the pipe 12 protrudes outside there. Then, the one side plane of the main body 1 is opened as shown in FIG. 1D, and the lid body 2 aligned with the opening is joined thereto with an adhesive or the like.

次に、本体１の平面にはフィン11が接着剤等により接合されている。そのフィン11は、円板状の基部を有し、その基部に多数の帯状金属板が突設されている。なお、フィン11の基部と本体１の平面とをビス止めすると共に、それらの間に伝熱性グリースを介在させても良い。
そして本体１の一方のパイプ12から腐蝕性の流体を流通させ、内部の流路３を蛇行状に流通して、他方のパイプ12からそれを流出させる。そして、フィン11に対向して図１（Ｂ）の如くファン13を配置し、ファン13による送風によって本体１内の腐蝕性流体を冷却することができる。なお、この例のフィン11の基部表面に放射方向へ突設された多数の帯状金属板は、夫々円弧状に形成されている。これは、ファン13による冷却風が遠心方向および回転方向の分力を有するので、それを効率的に捉えるようにしたものである。 Next, fins 11 are joined to the plane of the main body 1 with an adhesive or the like. The fin 11 has a disk-shaped base, and a large number of strip-shaped metal plates protrude from the base. Note that the base of the fin 11 and the flat surface of the main body 1 may be screwed, and heat transfer grease may be interposed between them.
Then, a corrosive fluid is circulated from one pipe 12 of the main body 1, and the internal flow path 3 is circulated in a meandering manner, and then flows out from the other pipe 12. Then, a fan 13 is disposed so as to face the fin 11 as shown in FIG. 1B, and the corrosive fluid in the main body 1 can be cooled by blowing air from the fan 13. Note that a large number of strip-shaped metal plates protruding in the radial direction on the base surface of the fin 11 in this example are each formed in an arc shape. This is because the cooling air from the fan 13 has component forces in the centrifugal direction and the rotational direction, so that it can be efficiently captured.

Has been.
Further, a pipe 12 projects from the outer peripheral header 7 on the main body 1 side, and a pipe 12 projects from the central header 6 on the lid 2 side as shown in FIG. The center header 6 may be formed in a pan shape. In that case, the pipe 12 protrudes in the center.

このような本体１と蓋体２とを互いに逆向きにして接着剤により接合することにより、本発明の樹脂製熱交換器を構成できる。
そして一例として、中心ヘッダ６側のパイプ12から腐蝕性流体を流入し、中心ヘッダ６および溝形部８を介し、外周ヘッダ７から他方のパイプ12にそれを流出させることができる。そして本体１または蓋体２に対向しファンを設け、その冷却風により内部の腐蝕性流通を冷却するものである。なお、この例ではファンを省略する。 The resin heat exchanger of the present invention can be configured by joining the main body 1 and the lid body 2 in the opposite directions and bonding them with an adhesive.
And as an example, corrosive fluid can flow in from the pipe 12 on the center header 6 side and flow out from the outer peripheral header 7 to the other pipe 12 via the center header 6 and the groove-shaped portion 8. Then, a fan is provided opposite to the main body 1 or the lid body 2, and the internal corrosive circulation is cooled by the cooling air. In this example, the fan is omitted.
