On the other hand, with respect to the container for liquefied natural gas automobile according to the present invention,

A support for supporting the inner wall and the outer wall at the lower side of the inside thereof may be configured, which will be described in addition to this structure.

This is a support structure for supporting between the inner wall and the outer wall at the lower side of the cryogenic container, and lowers the thermal conductivity by applying the material of the support that performs the supporting function to the FRP material, so that the cryogenic refrigerant contained in the inner wall is thermally conducted through the outer wall. It will be minimized.

In general, the cryogenic vessel is structurally configured to have a spaced space between the inner wall and the outer wall spaced apart, and a support for connecting the inner wall and the outer wall to the inner lower part for stable fixing of the inner wall and the outer wall.

However, in the conventional cryogenic container, as the support is configured, there is a problem in maintaining the internal temperature as the cold air (or the refrigerant) inside the inner wall is transferred to the outside of the outer wall through heat conduction through the support.

The present invention is to improve the structure and material of the support in order to solve this problem.

That is, for the container according to the present invention, the space between the inner wall and the outer wall is configured to include a first fixing part protruding downward from the inner wall and a second fixing part protruding upward from the outer wall (FIG. 1A). .

In this case, the first fixing part and the second fixing part may have a form in which two protrusions protrude as shown in the accompanying drawings, and may be configured to fix the support by being formed in a box shape that is opened one by one.

The support is inserted into and fixed to the first fixing part and the second fixing part, and one side of the supporting part fixed to the second fixing part allows all surfaces to be abutted on the outer wall and is fixed to the first fixing part. One side should be configured to be in contact with the first fixing portion, but the support is not in contact with the inner wall.

This support may be made of a material of the FRP.

The FRP is a plastic composite material reinforced with glass and carbon fiber, and is a high performance and high performance material having excellent light weight, corrosion resistance, and moldability. In addition, since the heat transfer rate is 1/180 of iron, it is known that thermal insulation and cold insulation are very excellent.

On the other hand, the support according to the invention as shown in Figure 1b may be configured as follows.

'의 형상을 갖으며, 뾰족한 영역이 마주하도록 구성될 수 있다. 즉, 위와 같이 1개의 제2 고정부에 대하여 1개의 돌기가 돌출되는 것이고, 도면과 같이 단면 기준으로 2개의 제2 고정부가 구성되는 경우, 각 1개마다 1개의 돌기가 돌출되기 때문에 2개로 구성된 돌기의 뾰족한 영역이 상호 마주하는 것이다.One protrusion may protrude in the inward direction where the support of the second fixing part contacts. At this time, the projection

It may have a shape of ', and may be configured to face sharp areas. That is, as described above, one projection protrudes from one second fixing part, and when two second fixing parts are configured on the basis of a cross section as shown in the drawing, one protrusion is protruded from each one so that two protrusions are formed. The sharp areas of the projections face each other.

The lower side of the support is supported on the upper side of the protrusion.

In addition, the inside of the support may be formed with a groove consisting of two stages of multi-stage. In addition, a cylinder including a cover and a rod inserted into the cover may be configured at the center of the region where the lower region of the inner wall of the outer wall touches, and the lower region of the inner wall of the outer wall may touch the end of the rod inserted into the cover. It can be configured to be connected via a spring with a region.

In addition, the other end of the rod of the cylinder may be configured to contact the inner top surface of the groove formed in the support.

With this structure, it is possible to have a shock-absorbing effect, as well as the minimum cold air transmitted through the support of the FRP material is not transmitted to the outer wall, but is discharged through the groove formed in the support, while the separation between the inner wall and the outer wall. You can stay in space.

On the other hand, by forming a hole penetrated in the width direction to one side corresponding to the area which becomes a blank area because the support of the first fixing part does not touch, the minimum cold air transmitted is to stay in the empty space between the support and the outside of the inner wall. Thus, the effect of preventing cold air in the inner wall from being transferred to the support can be expected.

What has been described above with reference to the drawings has been described only the main matters of the present invention, it is apparent that the present invention is not limited to the configuration of the drawings as long as various designs can be made within the technical scope.
