At present, most of the vacuum insulation panels are two-dimensional flat panels, and there are also VIP panels in which the flat panels are assembled into a ring, but the process is complicated, and the barrier film of the VIP itself is also damaged, which affects the performance and life of the VIP. The current barrel-type insulation and box-type insulation are commonly used for multi-sided splicing insulation of flat VIP panels; the marginal effect of VIP panels in this structure is obvious, and the cold bridge at the splicing of VIP panels seriously affects the overall thermal insulation performance. Therefore, although the thermal conductivity of VIP is 2.5mW/m·k, the thermal insulation performance is about 7 to 9 times better than that of pure PU, but the thermal insulation performance in the actual box is only 2 to 3 times better than that of pure PU. The performance improvement of thermal insulation VIP is not obvious, and the cost performance is slightly insufficient, which limits the application of VIP.

The inner container extends outward along the radial direction of the opening at the opening position and then extends upward along the axial direction of the opening to form an extension surface compounded with the barrier film; a sealing ring is compounded on the side of the extension surface facing the barrier film.

The inner liner is a metal inner liner, and the metal inner liner is formed by stamping and drawing or welding.

In a preferred embodiment, the intermediate core material is integrally formed with a gas silicon core material.

In a preferred embodiment, the intermediate core material comprises an annular sidewall glass fiber core material and a circular bottom surface glass fiber core material, the glass fiber core material is evacuated and wrapped with a plastic film.

In a preferred embodiment, the outer barrel-shaped barrier film is composed of an annular side film and a circular bottom film; the barrier film is a multi-layer composite aluminum-plastic film, which is compounded with the sealing ring on the extension surface of the inner tank. .

In a preferred embodiment, a closed space is formed between the outer barrel-shaped barrier film and the inner bladder, and the middle core material fills the space and is evacuated.

The present invention also provides a thermal insulation container using the above-mentioned 3D barrel-shaped vacuum insulation special-shaped plate.

Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

1. By making the VIP board into a 3D barrel-shaped structure, the barrel-shaped insulation requirements can be directly and completely wrapped, avoiding the marginal effect of a single VIP board and the cold bridge of the VIP splicing gap, thereby greatly improving the actual insulation effect of the VIP, thereby improving. Keep warm time.

2. The inner tank is a metal inner tank, which can be directly used in high temperature insulation fields such as water heater storage buckets, which solves the problem that VIP cannot directly contact high temperature objects.

3. The inner liner is a metal inner liner, and food-grade metal can be used to directly contact food, fresh food and medicine, as a turnover box in cold chain transportation. It is equivalent to directly wrapping the items with thermal insulation materials, which greatly improves the thermal insulation performance and application scenarios.
