Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] A 3D barrel type vacuum insulation panel such as figure 1 As shown, it includes an inner tank 1, an intermediate core material 2, and an outer barrel-shaped barrier film 3; the 3DVIP has an accommodating cavity and an opening; The outer extension forms an extension surface 12 , and an extension surface 13 is formed at the extension edge along the axial direction of the opening, and a sealing ring 14 is provided on the side of the extension surface 13 facing the barrier film.

[0020] The liner 1 is a metal liner, which is formed by stamping and stretching or welded, and does not leak air under vacuum conditions. The intermediate core material 2 is integrally formed of gas-silicon core material, or the intermediate core material includes a circular side wall glass fiber core material and a circular bottom surface glass fiber core materia...

Abstract

The invention provides a 3D barrel-shaped vacuum insulation panel. The vacuum insulation panel is provided with a containing cavity and an opening and specifically comprises an inner container, a middle core material and an outer-layer barrel-shaped barrier film, wherein the inner container extends outwards in the radial direction of the opening at the opening position and then extends upwards inthe axial direction of the opening to form an extending face compounded with the barrier film; and a sealing ring is compounded on the side, facing the barrier film, of the extending face. According to the 3D barrel-shaped vacuum insulation panel, the barrel-shaped heat preservation performance can be effectively enhanced, the heat preservation time is prolonged, and more energy conservation and environment protection are achieved. The invention further provides a heat preservation container using the 3D barrel-shaped vacuum insulation panel.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a 3D vacuum insulation panel. Background technique [0002] At present, most vacuum insulation panels are two-dimensional flat plates, and there are also VIP panels that roll flat plates into rings, but the process is complicated, and it also damages the barrier film of the VIP itself, affecting the performance and life of the VIP. The current barrel-type insulation and box-type insulation are commonly used for multi-face splicing of flat VIP panels; the marginal effect of VIP panels of 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 ...
