Definitions
- the present invention relates to a gas tank.
- a fuel cell vehicle equipped with a fuel cell and running on the electric power has been developed.
- a hydrogen tank (gas tank) that supplies hydrogen (fuel gas) to the fuel cell in addition to the fuel cell, a compressor that supplies air, and a refrigerant pump that circulates the refrigerant through the fuel cell
- a PDU Power Drive Unit
- converts DC power into AC power a motor for traveling, a drive train that transmits the driving force of the motor to the drive wheels, and the like.
- external devices such as a compressor, a refrigerant pump, a PDU, and a drive train generate heat as they operate.
- the hydrogen tank is filled with hydrogen at a high pressure, and a plurality of pressure reducing valves (regulators) are provided in the hydrogen supply channel through which hydrogen supplied from the hydrogen tank to the fuel cell flows. Then, the hydrogen target pressure is set according to the power generation requirement calculated based on the accelerator opening, etc., and the pressure reducing valve is controlled so that the secondary pressure of the pressure reducing valve becomes the calculated target pressure. is doing.
- an object of the present invention is to provide a gas tank in which the pressure of the gas filled therein is unlikely to increase.
- the present invention provides a container body filled with gas, a first heat insulating portion provided on the outer surface of the container body, and a part of the outer surface of the container body.
- a fixing member mounting region, a mounting surface that is a part of the surface of the fixing member is in contact with the fixing member mounting region, and is fixed to the outside so as to fix the container body to the outside, and other than the mounting surface
- a second heat insulating part provided on the surface of the fixing member.
- the 1st heat insulation part is provided in the outer surface of the container main body, the heat
- the mounting surface which is a part of the surface of the fixing member is in contact with the fixing member mounting region of the container body, and the fixing member is fixed to the outside (the vehicle body in the embodiment described later). It is fixed to the outside via.
- the 2nd heat insulation part is provided in surfaces other than the said attachment surface of a fixing member, the heat
- the heat of the external device is insulated by the first heat insulating portion provided on the outer surface of the container body and the second heat insulating portion provided on the surface other than the mounting surface of the fixing member.
- the temperature of the gas filled in the main body is unlikely to rise.
- the gas does not easily expand, that is, does not increase in volume, and the pressure of the gas in the container body does not increase easily.
- the first heat insulating portion and the second heat insulating portion are formed by applying a liquid or gel-like heat-foamable heat-insulating paint, and are foamed to become a heat-insulating layer when the temperature rises. It is characterized by being.
- Such a gas tank can easily constitute the first heat insulating portion and the second heat insulating portion only by applying a liquid or gel-like heat-foamable heat insulating paint.
- the first heat insulating portion is formed by applying a liquid or gel-like heat-foamable heat-insulating paint to the container body, and is a layer that foams and becomes a heat-insulating layer when the temperature rises.
- the second heat insulating portion is constituted by a heat insulating member (a heat insulating component having a heat insulating property) which is a solid object fixed to the fixing member.
- the first heat-insulating portion is easily configured, and a heat-insulating member (heat-insulating part having heat insulating properties) that is a solid material is used as a fixed member.
- a heat-insulating member heat-insulating part having heat insulating properties
- the 2nd heat insulation part can be constituted easily.
- the gas tank is mounted on a fuel cell vehicle equipped with a fuel cell, and the gas is a fuel gas supplied to the fuel cell.
- the pressure of the fuel gas filled in the container main body is unlikely to rise, so that the primary pressure of the pressure reducing valve (regulator) provided between the gas tank and the fuel cell increases with temperature. It becomes difficult to change. Therefore, it becomes easy to control the pressure reducing valve so that the target pressure is calculated based on the accelerator opening or the like. Therefore, the fuel gas is supplied excessively and is not consumed by the fuel cell and is not easily discharged as it is, and the fuel gas consumption efficiency, that is, the fuel consumption of the fuel cell vehicle is improved.

Abstract
Description
ここで、コンプレッサ、冷媒ポンプ、PDU、ドライブトレイン等の外部機器は、その作動に伴って発熱する。
このように、水素タンクにおける水素の圧力が上昇してしまうと、前記した減圧弁の一次側圧力も上昇することになり、前記目標圧力よりも高い圧力で、水素が燃料電池に供給される虞がある。そして、このように高い圧力で水素が供給されると、水素が燃料電池で良好に消費されず、そのまま車外に排出され、水素の消費効率(燃費)が低下する虞がある。
また、固定部材の表面の一部である取付面が容器本体の固定部材取付領域に接すると共に、固定部材が外部(後記する実施形態では車体)に固定されているので、容器本体は、固定部材を介して、外部に固定される。
さらに、固定部材の前記取付面以外の表面には、第2断熱部が設けられているので、外部機器の熱は、第2断熱部で断熱される。すなわち、外部機器の熱は、第2断熱部及び固定部材の内部を伝達しにくく、容器本体に入力されにくくなる。
したがって、減圧弁において、アクセル開度等に基づいて算出された目標圧力となるように制御しやすくなる。よって、燃料ガスが過剰に供給され、燃料電池で消費されずそのまま排出されにくくなり、燃料ガスの消費効率、つまり、燃料電池車の燃費も向上する。
本実施形態に係る燃料電池車100(車両、移動体)は、燃料電池スタック110(燃料電池)と、水素タンク1(ガスタンク)と、減圧弁121と、コンプレッサ131と、希釈器132と、を備えている。
なお、燃料電池車100の具体的種類には、例えば、四輪車、三輪車、二輪車、一輪車、列車等がある。
なお、配管132aには、ECUによって開度が制御される常開型の背圧弁(図示しない)が設けられている。すなわち、ECUは、アクセル開度に基づいて、発電要求量、目標空気圧力、目標水素圧力を算出し、目標空気圧力となるように、背圧弁の開度及びコンプレッサ131の回転速度を制御するようになっている。
次に、水素タンク1の具体的構造について、図2~図6を参照して説明する。
図2~図4に示すように、水素タンク1は、略円柱状の外形を有しており、燃料電池車100に対して横置きで搭載されている(図1参照)。
水素タンク1は、内部に水素が充填される容器本体10と、容器本体10の外表面11の全体に設けられた第1熱発泡性断熱層21(第1断熱部)と、容器本体10を固定するための2本のベルト31、31(固定部材)と、各ベルト31の表面32(取付面以外の表面)に設けられた第2熱発泡性断熱層41(第2断熱部)と、を備えている。
容器本体10は、アルミニウム合金製のライナ12と、ライナ12の外表面に設けられ、ライナ12を補強するCFRP層13(Carbon Fiber Reinforced Plastic層、炭素繊維強化プラスチック層)と、を備え、ライナ12の内部が、水素が充填されるタンク室14となっている。ライナ12の口金部(図示しない)には、ECUによって開閉制御されるインタンク電磁弁(一次遮断弁)を内蔵する弁装置15が螺合されている(図2、図3参照)。
ただし、容器本体10の具体的構造は、このようにライナ12とCFRP層13との二重構造に限定されず、例えば、合成樹脂製または金属製のライナのみから構成された一重構造のものでもよい。
第1熱発泡性断熱層21は、例えばポリ燐酸アンモニウム等の発泡剤を成分とする層であり、外部から加熱され温度上昇し、発泡温度に到達するとガスを発生することで発泡し、内部に多数の気泡が形成された第1断熱層(発泡層)を形成する層である。このような第1熱発泡性断熱層21は、例えばポリ燐酸アンモニウム等の発泡剤を成分とする公知である液状又はゲル状の熱発泡性断熱塗料を、容器本体10の外表面11全体に塗布することで容易に形成される。
2本のベルト31は、容器本体10を燃料電池車100の車体141(外部、周囲部材)に固定するための帯状体であり、本実施形態では、耐久性の高い金属製である。各ベルト31は、第1熱発泡性断熱層21の上から容器本体10に周方向で巻回されると共に、各ベルト31の両端部33、33がボルト34A及びナット34Bで締結されることで、各ベルト31は容器本体10に固定されている。
第2熱発泡性断熱層41、41は、図5に示すように、各ベルト31の表面32にそれぞれ設けられた帯状の層である。各第2熱発泡性断熱層41は、第1熱発泡性断熱層21と同様に、外部から加熱され温度上昇するとガスを発生することで発泡し、内部に多数の気泡が形成された第2断熱層41A(発泡層)を形成する層である(図6参照)。第2熱発泡性断熱層41の具体的組成、形成方法は、第1熱発泡性断熱層21と同様であるので、ここでの説明は省略する。
このような水素タンク1によれば次の作用効果を得る。
コンプレッサ131等の作動熱によって、第1熱発泡性断熱層21の温度が所定の発泡温度に上昇すると、第1熱発泡性断熱層21は発泡し、第1断熱層となる。また、第2熱発泡性断熱層41も所定の発泡温度に上昇すると発泡し、第2断熱層41Aとなる(図6参照)。
つまり、ベルト取付領域16における第1熱発泡性断熱層21は、ベルト31と容器本体10とで挟まれているので、発泡しにくいが、ベルト31の表面32に設けられた第2熱発泡性断熱層41が発泡し、第2断熱層41Aを形成するので、作動熱は第2熱発泡性断熱層41で断熱され、ベルト31部分を通って容器本体10に伝熱しない。
ただし、断熱部材42の固定方法は、接着剤等による接着固定方法に限定されず、例えば、ボルトで固定する方法でもよい。また、断熱部材42に爪を形成し、この爪によって断熱部材42を容器本体10にスナップフィット結合させる方法でもよい。
また、押さえ治具65の下面には、容器本体10の外形に対応して上方に凹んだ取付面67が形成されており、取付面67は容器本体10の外周面の上部に仮想的に設定された帯状の押さえ治具取付領域38B(固定部材取付領域)に、第1熱発泡性断熱層21を介して接している。
そして、コンプレッサ131の作動熱等によって、所定の発泡温度に上昇すると、第2熱発泡性断熱層64及び第2熱発泡性断熱層68は、それぞれ発泡して、断熱層を形成するようになっている。これにより、コンプレッサ131の作動熱等は、前記断熱層で良好に断熱され、台座61又は押さえ治具65内を伝達することはない。
また、ガスが天然ガスであり、CNG(Compressed Natural Gas)車に搭載されたものでもよいし、ガス燃料を充填して内燃機関や外燃機関に用いられてもよい。
