Description

本発明は燃料電池コージェネレーションシステムに関するものである。   The present invention relates to a fuel cell cogeneration system.

燃料電池コージェネレーションシステムは、燃料電池と、この燃料電池で発生させた直流電圧を交流電圧に変換するインバータ等を筐体内に配置した構成となっている。
また、燃料電池の冷却は、水冷により行っているものもある。（例えば下記特許文献１に記載されている）
特開２０００−２９４２６４号公報 The fuel cell cogeneration system has a configuration in which a fuel cell and an inverter that converts a DC voltage generated by the fuel cell into an AC voltage are arranged in a casing.
Some fuel cells are cooled by water. (For example, it is described in the following Patent Document 1)
JP 2000-294264 A

上記従来例において、燃料電池は水冷により十分冷却されることとなるが、上記インバータには大電流が流れるので、これも高温化することとなり、冷却の必要性がある。   In the above conventional example, the fuel cell is sufficiently cooled by water cooling, but since a large current flows through the inverter, this also increases the temperature, and there is a need for cooling.

よって、インバータにも水冷構造を取り入れることが考えられるが、水冷構造は、水漏れ対策の必要性から、構造が複雑で、その分大型化してしまう課題が発生する。   Therefore, it is conceivable to adopt a water cooling structure for the inverter. However, the water cooling structure is complicated in structure because of the necessity of countermeasures against water leakage, and there is a problem that the size is increased accordingly.

そこで本発明は、小型化を図ることを目的とするものである。   Accordingly, the present invention aims to reduce the size.

この目的を達成するために本発明は、筐体と、この筐体内部を、少なくとも大小の２室に実質的に仕切った仕切壁と、この仕切壁によって仕切られた前記大室に配置された燃料電池と、前記仕切壁によって仕切られた前記小室に配置されたインバータとを備え、前記大室に排気ファンを配置するとともに、前記仕切壁のインバータよりも上に小室用の排気口を設け、前記小室のインバータよりも下の筐体壁、または仕切壁に小室用の吸気口を設けたものであり、これによって所期の目的を達成するものである。   In order to achieve this object, the present invention is arranged in a casing, a partition wall that substantially partitions the interior of the casing into at least two chambers, and the large chamber partitioned by the partition wall. A fuel cell and an inverter disposed in the small chamber partitioned by the partition wall, and an exhaust fan is disposed in the large chamber, and an exhaust port for the small chamber is provided above the inverter in the partition wall; An inlet for a small chamber is provided on a housing wall or a partition wall below the inverter of the small chamber, thereby achieving an intended purpose.

以上のごとく本発明は、筐体と、この筐体内部を、少なくとも大小の２室に実質的に仕切った仕切壁と、この仕切壁によって仕切られた前記大室に配置された燃料電池と、前記仕切壁によって仕切られた前記小室に配置されたインバータとを備え、前記大室に排気ファンを配置するとともに、前記仕切壁のインバータよりも上に小室用の排気口を設け、前記小室のインバータよりも下の筐体壁、または仕切壁に小室用の吸気口を設けたものであり、大室の排気ファンを駆動すれば、大室に配置された燃料電池が空冷されることとなる。またこの排気ファンの駆動により、小室には、吸気口から排気口に向かう冷却風が発生し、これによってインバータも空冷されることとなる。   As described above, the present invention includes a housing, a partition wall that substantially partitions the interior of the housing into at least two chambers, and a fuel cell disposed in the large chamber partitioned by the partition wall; An inverter disposed in the small chamber partitioned by the partition wall, and an exhaust fan is disposed in the large chamber, and an exhaust port for the small chamber is provided above the inverter in the partition wall, and the inverter in the small chamber The lower chamber wall or partition wall is provided with an inlet for a small chamber, and if the exhaust fan of the large chamber is driven, the fuel cell disposed in the large chamber is air-cooled. In addition, by driving the exhaust fan, cooling air is generated in the small chamber from the intake port to the exhaust port, and thereby the inverter is also air-cooled.

そしてこのように前記大室の燃料電池と、前記小室のインバータが一つの排気ファンによって空冷されることとなるので、構造が簡単で、小型化することが出来るものとなる。   In this way, the fuel cell in the large chamber and the inverter in the small chamber are air-cooled by one exhaust fan, so that the structure is simple and the size can be reduced.

以下本発明の実施の形態について、図面を参照しながら説明する。   Embodiments of the present invention will be described below with reference to the drawings.

（実施の形態１）
図１、２は、本発明の実施の形態１における燃料電池コージェネレーションシステムの構成図である。
図１、２に示すごとく本実施形態では、長方形体の筐体１と、この筐体１内部を、少なくとも大室２、小室３の２室に実質的に仕切った仕切壁４と、この仕切壁４によって仕切られた前記大室２に配置された燃料電池５と、前記仕切壁４によって仕切られた前記小室３に配置されたインバータ６とを備えている。 (Embodiment 1)
1 and 2 are configuration diagrams of a fuel cell cogeneration system according to Embodiment 1 of the present invention.
As shown in FIGS. 1 and 2, in this embodiment, a rectangular housing 1, a partition wall 4 that substantially divides the interior of the housing 1 into at least two chambers 2 and 3, and this partition A fuel cell 5 disposed in the large chamber 2 partitioned by the wall 4 and an inverter 6 disposed in the small chamber 3 partitioned by the partition wall 4 are provided.

また、前記大室２の上部には、排気ファン７を配置するとともに、前記仕切壁４のインバータ６よりも上に小室３用の排気口８を設け、さらに前記小室３のインバータ６よりも下の筐体壁（または仕切壁４）に小室３用の吸気口９を設けている。   An exhaust fan 7 is disposed above the large chamber 2, an exhaust port 8 for the small chamber 3 is provided above the inverter 6 in the partition wall 4, and further below the inverter 6 in the small chamber 3. An inlet 9 for the small chamber 3 is provided in the casing wall (or partition wall 4).

このため、大室２の排気ファン７を駆動すれば、大室２下方の吸気口（図示せず）から吸気された冷却風で燃料電池５が空冷され、その後、空冷後の暖気は排気ファン７を介して筐体１外に排出されることとなる。   For this reason, when the exhaust fan 7 of the large chamber 2 is driven, the fuel cell 5 is cooled by the cooling air sucked from the intake port (not shown) below the large chamber 2, and then the warm air after the cooling is exhausted by the exhaust fan 7 is discharged to the outside of the housing 1 through 7.

また、上記排気ファン７の駆動により、吸気口９から排気口８へと向かう冷却風も発生し、この冷却風により、インバータ６の空冷が効果的に行われることとなり、その後、この空冷後の暖気も排気ファン７を介して筐体１外に排出されることとなる。   Further, the driving of the exhaust fan 7 also generates cooling air from the intake port 9 to the exhaust port 8, and the cooling air effectively cools the inverter 6. Warm air is also discharged out of the housing 1 through the exhaust fan 7.

ここで、前記仕切壁４によって仕切られた前記小室３にインバータ６を配置した理由は、この小室３内を流れる冷却風がインバータ６の外周に触れやすくするためで、これによって、インバータ６の冷却効果は極めて高くなる。   Here, the reason why the inverter 6 is arranged in the small chamber 3 partitioned by the partition wall 4 is to make it easy for the cooling air flowing in the small chamber 3 to touch the outer periphery of the inverter 6, thereby cooling the inverter 6. The effect is extremely high.

また、前記仕切壁４のインバータ６よりも上に小室３用の排気口８を設け、さらに前記小室３のインバータ６よりも下の筐体壁（または仕切壁４）に小室３用の吸気口９を設けたのは、小室３による煙突効果を利用するためで、この結果としてインバータ６の冷却効果は極めて高くなる。   Further, an exhaust port 8 for the small chamber 3 is provided above the inverter 6 of the partition wall 4, and an intake port for the small chamber 3 is provided on the housing wall (or the partition wall 4) below the inverter 6 of the small chamber 3. 9 is provided because the chimney effect of the small chamber 3 is used, and as a result, the cooling effect of the inverter 6 becomes extremely high.

また、この小室３には、燃料電池５やインバータ６の動作制御をするための制御基板１０が配置されており、これにより制御基板１０も吸気口９から排気口８へと向かう冷却風によって冷却されることとなる。   In addition, a control board 10 for controlling the operation of the fuel cell 5 and the inverter 6 is disposed in the small chamber 3, whereby the control board 10 is also cooled by cooling air from the intake port 9 to the exhaust port 8. Will be.

また、本実施形態において、小室３用の排気口８の開口中心は、排気ファン７の中心部よりも高所の仕切壁４部分に設けているが、その理由は大室２内の暖気が進入しないようにするためである。   In the present embodiment, the center of the opening of the exhaust port 8 for the small chamber 3 is provided in the partition wall 4 part higher than the central portion of the exhaust fan 7 because the warm air in the large chamber 2 is This is to prevent entry.

なお、排気ファン７部分には、雨水が筐体１内に入らないようにするためと、防音の役目も兼ねるフード１１を設けている。   The exhaust fan 7 is provided with a hood 11 that prevents rainwater from entering the housing 1 and also serves as a soundproofing function.

（実施の形態２）
図３、４は、本発明の実施の形態２の燃料電池コージェネレーションシステムの構成図である。図３、４において、図１、２と同じ構成要素については同じ符号を用い、説明を簡略化する。 (Embodiment 2)
3 and 4 are configuration diagrams of the fuel cell cogeneration system according to the second embodiment of the present invention. 3 and 4, the same reference numerals are used for the same components as those in FIGS.

図３、４においては、インバータ６を仕切壁４の排気口８近傍にまで上昇配置したものである。つまり、このような構成にすれば、インバータ６を小室３内における冷却風流路の最も下流に配置することになるので、インバータ６による他部品（例えば制御基板１０）への悪影響を小さくすることが出来る。
なお、上記実施の形態１、２において排気口８は仕切壁４に開口させて構成したが、この小室３用の排気口８は、仕切壁４の上端と筐体１の下面との間に間隙を設けて構成し手も良い。 3 and 4, the inverter 6 is arranged up to the vicinity of the exhaust port 8 of the partition wall 4. That is, with such a configuration, the inverter 6 is arranged on the most downstream side of the cooling air flow path in the small chamber 3, so that the adverse effect of the inverter 6 on other components (for example, the control board 10) can be reduced. I can do it.
In the first and second embodiments, the exhaust port 8 is configured to open to the partition wall 4. However, the exhaust port 8 for the small chamber 3 is provided between the upper end of the partition wall 4 and the lower surface of the housing 1. It is constructed with a gap and is good.

本発明の燃料電池コージェネレーションシステムは、小型化できるので、家庭用としても簡単に設置することが出来るようにもなり、極めて有用なものである。   Since the fuel cell cogeneration system of the present invention can be miniaturized, it can be easily installed even for home use, and is extremely useful.
