Description

극저온 연료 탱크 및 자동차 내에서의 그의 사용{Cryogenic fuel tank and use thereof in a motor vehicle}Cryogenic fuel tank and use in a motor vehicle

본 발명은 극저온 연료 탱크에 관한 것으로, 특히 외피(outer envelope) 및 내피(inner envelope)를 포함하며, 내피와 외피 사이의 공간은 다층 단열 구조물에 의해 점유되는 액체 극저온 연료의 내장식 저장조(onboard storage)에 대한 것이다.FIELD OF THE INVENTION The present invention relates to cryogenic fuel tanks, in particular comprising an outer envelope and an inner envelope, wherein the space between the inner and outer shells is an onboard storage of liquid cryogenic fuel occupied by a multilayer insulating structure. )

다층 단열부를 갖는 탱크의 제조는 인건비 측면에서 상당한 어려움을 갖는다. 다층 단열부의 제조의 자동화는 (액체를 충전 및 배출, 가스 상(phase)을 배출, 다양한 접속부 등) 다수의 접속부 및 탱크로 유입 및 유출되는 배관 때문에 가설로 남아 있다. 또한, 내측 탱크에 대한 지지는 비전도 재료로 만들어진 상대적으로 복잡한 스트럿(strut) 또는 접착 결합 시스템에 의해 일반적으로 얻어지는데, 제조자에 의해 부과된 높은 수준의 가속도를 견뎌내기 위해, 자동차용 탱크의 특수한 경우에는 기계적으로 초과설계되어야만 한다. 이러한 접착제 또는 스트럿 그리고 배관 기구나 도선(conductor)에 대한 접속점은 탱크의 만족스러운 단열을 해치는 불연속부를 발생시키며 탱크의 열적 성능을 감소시키는 열의 유입에 대한 상당한 원인을 구성한다. The production of tanks with multilayer insulation has significant difficulties in terms of labor costs. The automation of the manufacture of multilayer insulations remains hypothetical because of the number of connections and piping entering and exiting the tank (filling and discharging liquids, discharging gas phases, various connections, etc.). In addition, support for the inner tank is generally obtained by a relatively complex strut or adhesive bonding system made of non-conductive material, in order to withstand the high level of acceleration imposed by the manufacturer. In such cases, it must be overdesigned mechanically. These adhesives or struts, as well as the connection points for plumbing fixtures or conductors, create discontinuities that compromise satisfactory thermal insulation of the tank and constitute a significant source of heat inflow that reduces the tank's thermal performance.

본 발명의 목적은 전술한 단점을 크게 감소시키고, 간단하고 효과적인 방식으로 향상된 단열성 및 향상된 내충격성을 갖는 탱크의 제조를 가능하게 하는 극저온 유체 탱크 구조물을 제공하는 것이다.It is an object of the present invention to provide a cryogenic fluid tank structure which greatly reduces the aforementioned disadvantages and enables the production of tanks with improved thermal insulation and improved impact resistance in a simple and effective manner.

이러한 목적을 위해, 본 발명의 일 특징에 따르면, 내피는 외측 탱크에 고정되고 외측 탱크 내부로 연장되는 지지 구조물에 의해 형성된 피봇 지점 상에 내피가 지지되며, 피봇 지점은 내측 탱크의 무게 중심 상측에 위치된다. For this purpose, according to one feature of the invention, the endothelium is supported on a pivot point formed by a support structure fixed to the outer tank and extending into the outer tank, the pivot point being above the center of gravity of the inner tank. Is located.

본 발명의 또다른 더욱 상세한 특징에 따르면, According to another more detailed feature of the invention,

-지지 구조물은 내측 탱크의 중공 체적 내부에서 통상 수직축을 구비하며 연장되고,The support structure extends, usually with a vertical axis, inside the hollow volume of the inner tank,

-내피는 종방향 축을 갖는 대체로 원통형인 구성을 가지며, The endothelium has a generally cylindrical configuration with a longitudinal axis,

-전기 신호 또는 유체를 전달하기 위한 라인(line)은 지지 구조물 내로 외측으로 연장되는 내피의 내부와 연통한다. A line for conveying an electrical signal or fluid communicates with the interior of the endothelium extending outward into the support structure.

또한, 본 발명은 특히 견인을 위해, 차량에 의해 사용될 수 있는 에너지 유체를 저장하기 위한 자동차에서의 이러한 탱크의 사용에 관한 것이다. The invention also relates to the use of such tanks in motor vehicles for storing energy fluids that can be used by vehicles, especially for towing.

본 발명의 다른 특징 및 장점은 제한의 방식이 아닌 예시의 방식으로 주어진 첨부된 도면에 관한 이하의 실시예로부터 명백하게 될 것이다.Other features and advantages of the invention will be apparent from the following examples of the accompanying drawings, which are given by way of example and not by way of limitation.

도1은 본 발명에 따른 탱크의 실시예의 종방향 개략 단면도이다.1 is a longitudinal schematic cross-sectional view of an embodiment of a tank according to the invention.

도2는 도1의 탱크의 개략 단면도이다.2 is a schematic cross-sectional view of the tank of FIG.

도3은 도1의 탱크의 피봇 영역의 일례의 개략적인 부분 단면도이다. 3 is a schematic partial cross-sectional view of an example of the pivot region of the tank of FIG.

도1 및 도2에서, 탱크 구조물은 외피(2) 내에 전체적으로 위치된 내피(1) 내에 한정된, 액체 극저온 유체(L)의 저장조에 대해서 도시될 수 있으며, 내피(1)와 외피(2) 사이의 공간은 다층 단열 구조물(3)에 의해 점유되며 고진공(high vacuum)하에 놓여진다.1 and 2, the tank structure can be shown for a reservoir of liquid cryogenic fluid L, defined in an endothelial 1, which is located entirely within the shell 2, between the shell 1 and the shell 2. The space of is occupied by the multi-layered insulating structure 3 and placed under high vacuum.

본 발명의 일 특징에 따르면, 다층 단열 구조물(3)은 양호하게는 알루미늄 처리된 마일라(aluminized MYLAR™)형의 폴리에틸렌 테레프탈 그리고 덱스터(Dextar™) 또는 리달(Lydall™) 형의 유리섬유 종이의 층들로 이루어진 교번하는 반사/개재 층들로 구성된다. 외피와 내피 사이의 공간에서의 진공은 통상 10-4밀리바아 이하의 압력에 있다.According to one feature of the invention, the multi-layered insulating structure 3 is preferably made of aluminized MYLAR ™ type polyethylene terephthal and Dexter ™ or Lydall ™ type fiberglass paper. It consists of alternating reflective / intervening layers of layers. The vacuum in the space between the sheath and the endothelium is typically at a pressure of less than 10 −4 millibars.

도1 및 도2에서 명확하게 알 수 있는 바와 같이, 내피(1) 및 외피(2)는 서로에 대해 동축으로 배열된 수평 종방향 축을 구비하는 대체로 원통형 구성을 갖는다. 본 발명의 일 특징에 따르면, 내피(1)는 탱크 사용시의 통상적인 배치 상태에서 액체(L)의 저장조를 둘러싸는 내피(1)의 무게 중심(G)의 상측에 위치한 A 지점에서 피봇 방식으로 지지된다. 피봇 지점(A)은 종(bell) 형상의 구조물(5)의 기부(4)와, 관형 구조물(6)의 상단부 사이에 형성되며, 종 형상의 구조물(5)은 이 구조물(5)이 고정되는 내피(1)의 기부로부터 내피의 상부벽 근처까지 수직 방향으로 연장되고, 관형 구조물(6)은 이 구조물(6)이 고정되는 내피(1)의 기부로부터 종 형 상 구조물(5)의 내부에서 구조물(5)과 동축으로 수직으로 연장된다. 검사 및 보수를 위한 해체를 용이하게 하기 위해서, 종 형상 구조물(5) 및 관형 구조물(6)은 도1에 도시된 것과 같은 플랜지의 시스템에 의해 내피(1) 및 외피(2)에 조립될 수 있다.As can be clearly seen in FIGS. 1 and 2, the endothelium 1 and the envelope 2 have a generally cylindrical configuration with horizontal longitudinal axes arranged coaxially with respect to one another. According to one feature of the invention, the endothelium 1 is pivotally pivoted at point A, located above the center of gravity G of the endothelium 1 surrounding the reservoir of liquid L in a conventional arrangement of the tank. Supported. The pivot point A is formed between the base 4 of the bell-shaped structure 5 and the upper end of the tubular structure 6, the bell-shaped structure 5 being fixed by the structure 5. Extending in a vertical direction from the base of the endothelial 1 to the vicinity of the upper wall of the endothelial, the tubular structure 6 extending from the base of the endothelial 1 to which the structure 6 is fixed. Extends perpendicularly coaxially with the structure (5). To facilitate dismantling for inspection and repair, the bell-shaped structure 5 and the tubular structure 6 can be assembled to the endothelium 1 and the shell 2 by a system of flanges as shown in FIG. have.

도1 및 도2에 도시되는 바와 같이, 내피(1)로 액체를 충전하기 위한 라인(7), 내피(1) 내의 액체(L)의 수준을 측정하기 위한 탐침(8) 또는 내피(1)의 가스의 제거(take-off) 라인(9)과 같은 내피(1) 내부에서의 유체 또는 전기 신호를 전달하기 위한 모든 장치들은 피봇 지점(A) 부근에서 종 형상 구조물(5)과 관형 구조물(지지부;6)의 기부 벽들을 관통하여 관형 지지부(6)를 통해 외피(2)의 외부로 연장되며, 통상 역시 진공하에 놓여진 밸브(11)를 둘러싸는 밸브 하우징(10)을 통과한다.1 and 2, a line 7 for filling liquid into the endothelium 1, a probe 8 or an endothelium 1 for measuring the level of the liquid L in the endothelium 1. All devices for transmitting fluid or electrical signals inside the endothelium 1, such as the take-off line 9 of the gas, are provided with a bell-shaped structure 5 and a tubular structure near the pivot point A. Penetrates the base walls of the support 6 and extends through the tubular support 6 to the outside of the shell 2 and passes through the valve housing 10, which also surrounds the valve 11, which is also placed under vacuum.

이러한 구성에 의해, 내피(1)는 외피(2) 내에 진자 방식으로 매달리고, 외부 및/또는 내부 가속도의 영향 하에서 피봇 지점(A)에 대한 내피(1)의 각 회전(angular swinging)은 내피(1)와 외피(2) 사이의 밀집된 단열 구조물(3)에 의해 즉각적으로 완충되며, 내피는 단순히 중력에 의해 가속도가 없는 휴식 상태의 균형 잡힌 배치를 자동으로 회복한다. 그러므로, 본 발명에 따라서 내피는 다수의 사고에 대해 보호되며, 이것은 이러한 내피의 주위에의 단열부의 설치를 단순화하고 자동화하는 것을 가능하게 한다. 또한, 파이프와 도선이 벽을 통과하는 지점들은 내피(1) 내의 지점(A) 주위의 좁은 피봇 영역 내에 함께 모이기 때문에, 외부로 향하는 모든 열적 브리지(bridge)를 크게 감소시킨다. With this arrangement, the endothelium 1 hangs in a pendulum manner within the envelope 2, and the angular swinging of the endothelium 1 with respect to the pivot point A under the influence of external and / or internal acceleration is carried out by the endothelium ( Immediately cushioned by a dense insulating structure 3 between 1) and the sheath 2, the endothelium automatically recovers a balanced arrangement of restless states with no acceleration simply by gravity. Therefore, in accordance with the present invention the endothelium is protected against a number of accidents, which makes it possible to simplify and automate the installation of the insulation around the endothelium. In addition, the points through which the pipes and conductors pass through the wall gather together in a narrow pivot area around point A in the endothelium 1, thus greatly reducing all thermal bridges to the outside.

도3에 도시된 특정 실시예에서, 피봇 지점(A)은 종 형상 구조물(5)의 기부(4)와 지지 구조물(6)의 상부를 폐쇄하는 단부 벽(12)의 사이의 볼 조인트 조립체에 의해 만들어지며, 예컨대 연질(annealed) 스테인레스 강에서, 기부(4)와 단부 벽(12) 사이의 라인 접합은 가요성 접속부(13)에 의해 제공된다. In the particular embodiment shown in FIG. 3, the pivot point A is connected to the ball joint assembly between the base 4 of the bell-shaped structure 5 and the end wall 12 closing the top of the support structure 6. Made, for example in annealed stainless steel, a line junction between the base 4 and the end wall 12 is provided by the flexible connection 13.
