Description

本発明は、低温流体用のタンクに関し、特に、外殻と内殻とを含み、前記外殻と前記内殻との間の空間が多層絶縁構造で占められているタイプの、積載される液体低温燃料のストレージの為の低温流体用のタンクに関する。   The present invention relates to a tank for a cryogenic fluid, and in particular, a liquid to be loaded of a type including an outer shell and an inner shell, and a space between the outer shell and the inner shell is occupied by a multilayer insulating structure. The present invention relates to a tank for cryogenic fluid for storage of cryogenic fuel.

多層絶縁を有するタンクの生産は、マンパワーコストの点で、かなりの困難が存在する。多層絶縁の製造のオートメーション化は、タンクへ入出（液体の充填及び引き出し、気体相の引き出し、さまざまな接続、等）する多数の接続とパイピング故に仮定のままである。さらに、内タンクの支持は、通常、接着剤ボンディングシステムまたは不伝導性材料から作られた比較的高度な支柱という手段で得られる。そして、前記内タンクの支持は、自動車両のタンクの特別なケースにおいては、製造者によって課される高いレベルの加速に耐え得るように機械的にオーバーデザインされたに違いない。これら接着剤あるいは支柱、及びパイプワークの接続ポイントあるいは伝導体は、タンクの十分な絶縁を阻害する不連続点を生み出し、タンクの伝熱能力を減少させる熱の入り口として大きなソースを構成する。   Production of tanks with multi-layer insulation presents considerable difficulties in terms of manpower costs. The automation of the production of multi-layer insulation remains hypothesized due to the large number of connections and piping entering and exiting the tank (liquid filling and withdrawal, gas phase withdrawal, various connections, etc.). Furthermore, the support of the inner tank is usually obtained by means of an adhesive bonding system or a relatively advanced strut made from a non-conductive material. And the support of the inner tank must be mechanically overdesigned to withstand the high level of acceleration imposed by the manufacturer in the special case of the tank of a motor vehicle. These adhesives or struts, and pipework connection points or conductors create discontinuities that impede sufficient insulation of the tank and constitute a large source of heat that reduces the heat transfer capacity of the tank.

本発明の目的は、上述の不都合を大きく減少させ、シンプル且つ効果的な方法で、熱絶縁を改良し且つ改善された衝撃抵抗度をも有する低温流体用のタンク構造を提供することである。   It is an object of the present invention to provide a cryogenic fluid tank structure that greatly reduces the above disadvantages, improves thermal insulation and also has improved impact resistance in a simple and effective manner.

この目的を達する為に、本発明の一つの特徴によれば、前記内殻は、外タンクに固定され且つ外タンクの中まで伸びた支持構造によって形成されるピボットポイントで支持され、前記ピボットポイントは、内タンクの重力の中心上に位置する。   To this end, according to one aspect of the invention, the inner shell is supported by a pivot point formed by a support structure fixed to the outer tank and extending into the outer tank, the pivot point being Is located on the center of gravity of the inner tank.

本発明のその他の特別の特徴によれば、
支持構造は、一般的には垂直軸を有し、内タンクの中空の容積の内部にて拡がっており、
内殻は、縦軸を有し且つ略円筒型構造を採り、
流体を輸送するラインまたは内殻の内部と通信する電気的信号のラインは、外側へ向かって前記支持構造の内部へ伸びている。 According to other special features of the invention,
The support structure generally has a vertical axis and extends within the hollow volume of the inner tank,
The inner shell has a longitudinal axis and takes a substantially cylindrical structure,
A line for transporting fluids or a line for electrical signals communicating with the interior of the inner shell extends outwardly into the support structure.

本発明はまた、特にその牽引において、車両によって使用され得るエネルギー流体を貯蔵するような自動車両におけるタンクの使用に関する。   The present invention also relates to the use of a tank in a motor vehicle that stores energetic fluid that can be used by the vehicle, particularly in its towing.

添付され、非限定的な例として与えられている図面を参照している以下の実施形態の記載から、本発明の他の特徴及び利点が明確にされる。   Other features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying drawings, given by way of non-limiting example.

図１及び図２では、タンクの構造は、完全に外殻２の内側に配置された内殻１内に閉じ込められた液体低温流体Ｌを貯蔵し、前記殻１及び２の間のスペースは多層絶縁構造３によって占められ且つ高真空下に置かれている。   In FIG. 1 and FIG. 2, the tank structure stores liquid cryogenic fluid L confined in an inner shell 1 disposed entirely inside the outer shell 2, and the space between the shells 1 and 2 is multi-layered. It is occupied by an insulating structure 3 and placed under high vacuum.

本発明の一つの特徴によれば、多層絶縁構造３は、有益に、アルミ化ミラー（Ｍｙｌａｒ（登録商標））タイプのポリエチレンテレフタル層及びデクスター（Ｄｅｘｔａｒ）タイプまたはリドール（Ｌｙｄａｌｌ（登録商標））タイプのガラスファイバーペーパーから成る交互に反射／インターリーブされた層から成る。前記殻の間の空間の真空度は、一般的には１０−４ミリバールより低い。 According to one feature of the present invention, the multi-layer insulation structure 3 is advantageously made of an aluminized mirror (Mylar®) type polyethylene terephthalate layer and a Dexter type or Ridol (Lydal®) type. Consisting of alternating reflective / interleaved layers of glass fiber paper. The degree of vacuum in the space between the shells is generally lower than 10-4 mbar.

図１及び図２に明確に見られるように、前記殻１及び２は、互いに関して同軸上に配列された水平縦軸を有する略円筒型構造を採る。本発明の一特徴によれば、内殻１は、液体Ｌの貯蔵庫を囲む前記殻１の重力の中心上のタンクの使用における通常の構造中に位置するポイントＡにおいて、旋回運動方法によって支持される。前記ピボットポイントＡは、内殻１の底から、これに固定された内殻１の上壁の近傍まで、垂直に伸びている鐘型構造５の底４と、内殻１の底からベル５の中まで同軸上に垂直に伸びている管状構造６の上端部の傍との間に形成されている。検査及びメンテナンスの為の設備の解体を円滑にする為に、鐘型構造５及び管状構造６は、図１に示すように、フランジのシステムによって、前記殻１及び２に組み立てられ得る。   As clearly seen in FIGS. 1 and 2, the shells 1 and 2 take a generally cylindrical structure with a horizontal longitudinal axis arranged coaxially with respect to each other. According to one characteristic of the invention, the inner shell 1 is supported by a swivel movement method at a point A located in the usual structure in the use of a tank on the center of gravity of the shell 1 surrounding the reservoir of liquid L. The The pivot point A includes the bottom 4 of the bell-shaped structure 5 extending vertically from the bottom of the inner shell 1 to the vicinity of the upper wall of the inner shell 1 fixed thereto, and the bell 5 from the bottom of the inner shell 1. Between the upper end of the tubular structure 6 extending coaxially and vertically to the inside. In order to facilitate the dismantling of the equipment for inspection and maintenance, the bell-shaped structure 5 and the tubular structure 6 can be assembled to the shells 1 and 2 by a flange system, as shown in FIG.

図１及び図２に示すように、例えば内殻１の中に液体を注入するためのライン７や、内殻１の中の液体Ｌの水位を計測する為のプローブ８や、内殻１のガスネック（ｔｈｅ ｇａｓ ｎｅｃｋ）のテイクオフライン（ｔｈｅ ｔａｋｅ−ｏｆｆ ｌｉｎｅ）９のような、流体を移送するデバイスまたは内殻１の内部で発生した電気的信号を伝達するデバイスは全て、ピボットポイントＡの近傍のベル５の底壁及び管状支持材６を通って、一般的には真空下に設置されたバルブ１１を囲っているバルブハウジング１０を通って、外殻２の外部へ向かって管状支持材６の中へ伸びている。   As shown in FIGS. 1 and 2, for example, a line 7 for injecting liquid into the inner shell 1, a probe 8 for measuring the water level of the liquid L in the inner shell 1, and the inner shell 1 All devices that transfer fluids or transmit electrical signals generated inside the inner shell 1, such as the take-off line 9 of the gas neck, are all in the vicinity of the pivot point A Through the bottom wall of the bell 5 and the tubular support 6, generally through the valve housing 10 surrounding the valve 11 installed under vacuum, and toward the outside of the outer shell 2. It extends into.

そのようなアレンジメントによって、内殻１は、前記殻１及び２の間に詰められた絶縁構造３によって即座に減衰された外部及び／または内部加速度の影響の下、ピボットポイントＡに関して内殻１の振れ角度で、振り子のように外殻２内部を浮遊し、加速の無い時に、そのバランスのとれた構造と単純に重力によって、前記内殻は自動的に正常な状態に戻ることが分かる。本発明によれば、それゆえ、前記内殻は、たくさんのアクシデントからプロテクトされており、このことが、この殻の周辺の絶縁材の取り付けの単純化及び自動化を可能にする。さらに、パイプ及び伝導体が壁を通るポイントは、外部への全ての熱ブリッジ（ｔｈｅｒｍａｌ ｂｒｉｄｇｅｓ）を大きく減少させるこの方法で、内殻１中のポイントＡ周辺の狭いピボットゾーンにてグループ化されている。   With such an arrangement, the inner shell 1 can be moved with respect to the pivot point A under the influence of external and / or internal acceleration which is immediately damped by the insulating structure 3 packed between the shells 1 and 2. It can be seen that the inner shell automatically returns to a normal state due to its balanced structure and simply gravity when the outer shell 2 floats like a pendulum at a swing angle and there is no acceleration. According to the invention, the inner shell is therefore protected from a number of accidents, which makes it possible to simplify and automate the installation of the insulation around the shell. In addition, the points through which the pipes and conductors pass through the walls are grouped in a narrow pivot zone around point A in the inner shell 1 in this way, which greatly reduces all the thermal bridges to the outside. Yes.

図３に示す特別な実施形態においては、ピボットポイントＡは、ベル５の底４と支持構造５の頂点、１３のような例えばなまされたステンレス鋼のようなフレキシブル接続によって提供されている底４と底壁１２との間のラインジャンクション、を閉じる壁端部１２との間のボールジョイント組み立て部という手段によって作られている。   In the special embodiment shown in FIG. 3, the pivot point A is provided by a flexible connection, such as annealed stainless steel, such as the bottom 4 of the bell 5 and the apex of the support structure 5, 13. 4 is made by means of a ball joint assembly between the wall end 12 and the line junction between the bottom wall 12 and the line junction.

本発明は特定の実施形態との関係で記述されているが、それに限られることは無く、下記のクレームの文脈内の技術に熟練した人にとって明白な変更及び変形も可能である。そして、図１乃至図３の実施形態の変形としては、管状支持材は、上方が開放され且つ内殻の頂点から下方へ重力Ｇの中心上に位置するポイントへ向かって伸びた短縮鐘型構造の中で、外殻２の頂点から下方へ伸長し得る。また、垂直なベル５の中に同様に垂直に伸びた管状支持材６に代えてピボットポイントＡが、水平に伸びた管状支持構造の上母線の間に、外殻２に面するドーム状の端部の間に、内殻１内で水平方向にも形成された管状中空容量の中へ向かうように、軸の方向に対向して湾曲したその端部の間に、内殻１が上方に向かって中心を外れた（ｏｆｆ−ｃｅｎｔｅｒ）中空容量を有する略管状構造を示しているように形成され得る。この場合もまた、接続ライン及び伝導体は、ピボットゾーンから外側へ向かって水平管状支持材の中へ向かって、水平管状支持材に沿って伸びている。   While the invention has been described in connection with specific embodiments, it is not limited thereto and modifications and variations that are obvious to those skilled in the art within the context of the following claims are possible. As a modification of the embodiment of FIGS. 1 to 3, the tubular support member has a shortened bell-shaped structure that is open upward and extends downward from the top of the inner shell toward a point located on the center of gravity G. In the case, it can extend downward from the top of the outer shell 2. Similarly, instead of the tubular support 6 extending vertically in the vertical bell 5, the pivot point A has a dome-like shape facing the outer shell 2 between the upper buses of the horizontally extended tubular support structure. Between the ends, the inner shell 1 faces upwards between its ends curved in the axial direction so as to go into the tubular hollow volume also formed in the horizontal direction in the inner shell 1. It can be formed to show a generally tubular structure with a hollow volume off-center. Again, the connecting lines and conductors extend along the horizontal tubular support from the pivot zone outward and into the horizontal tubular support.
