Technical Field
The invention relates to the field of heat insulation materials, in particular to a 3D vacuum heat insulation plate.
Background
At present, most of vacuum insulation panels are two-dimensional flat plates, and some VIP plates are formed by rolling flat plates into rings, but the processes are complex, and the VIP insulation panels also damage barrier films of the VIP and influence VIP performance and service life. The flat VIP is rolled into an annular structure, and the cold leakage at the splicing part of the VIP plate is serious, so that the integral heat insulation performance is influenced; and the folds of the inner layer barrier film greatly improve the air leakage proportion of the VIP plate and improve the use cost of the VIP. The heat preservation performance is not ideal due to the application of VIP, the reject ratio is high, and the application of VIP in the field of annular heat preservation is limited.
Disclosure of Invention
The invention aims to solve the problems of insufficient performance and high reject ratio of flat VIP in annular heat insulation application, and provides an annular vacuum heat insulation plate which is applied to annular heat insulation, has no cold leakage of splicing parts, greatly enhances the heat insulation performance, and simultaneously ensures the yield of VIP, thereby improving the cost performance of VIP application, and being more energy-saving and environment-friendly.
In order to solve the above technical problem, the present invention provides a 3D annular vacuum insulation panel, comprising: the inner barrier layer, the middle core material and the outer barrier layer;
the inner barrier layer is annular, and two ends of the inner barrier layer along the axial direction are opening surfaces; the outer barrier layer comprises an outward convex part protruding outwards along the radial direction of the inner barrier layer and straight parts arranged on the upper side and the lower side of the outward convex part along the axial direction of the inner barrier layer; the straight portion is compounded with the inner barrier layer to form a closed space for filling the intermediate core material between the convex portion and the inner barrier layer.
In a preferred embodiment: the inner barrier layer is made of metal or aluminum-plastic film; the helium mass spectrum leakage rate of the inner barrier layer is less than 10 under the vacuum condition-4Pa.l/s.cm2。
In a preferred embodiment: the middle core material is integrally formed or a flat core material is rolled into a circular ring shape.
In a preferred embodiment: the outer layer barrier film is made of metal or aluminum-plastic film; the helium mass spectrum leakage rate of the outer layer barrier film is less than 10 under the vacuum condition-4Pa.l/s.cm2。
In a preferred embodiment: the closed space is a vacuum space.
The invention also provides a heat preservation container, which uses the 3D annular vacuum heat insulation plate.
Compared with the prior art, the technical scheme of the invention has the following beneficial effects:
1. through making the VIP board into 3D annular structure, can directly wrap up annular adiabatic demand completely, do not keep the gap, avoided dull and stereotyped VIP board to curl the gap that the concatenation of head and tail formed to improve the VIP actual heat preservation effect greatly, thereby it is long when improving to keep warm.
2. The inner layer barrier layer can be made of metal materials, can be directly applied to the high-temperature heat insulation field such as a water storage barrel of a water heater, and solves the problem that an aluminum plastic film can not directly contact with a high-temperature object.
3. The inner container is a metal inner container, can adopt food-grade metal, and is in direct contact with food, fresh food and medicines. The method is equivalent to directly wrapping objects with heat-insulating materials, so that the heat-insulating performance and the application scene are greatly improved.
4. When the inner layer adopts the aluminum-plastic barrier film, the transition wrinkles of the inner layer barrier film are avoided, the yield of products is improved, and the cost is reduced.
