Abstract

The utility model provides a vacuum insulation panel and an insulation box, which can improve gaps when the vacuum insulation panel is spliced and reduce cold and heat loss in the use process. The vacuum insulation panel comprises a core material and an outer bag. The length and width of the outer bag are larger than those of the core material. The panel of the core material comprises a first surface and a second surface which are oppositely arranged. The redundant part of the outer bag comprises a first edge, a second edge and a corner, and the redundant part is attached and fixed with the core material by utilizing a turnover structure. The folding structure comprises a first folding edge unit, a folding angle unit and a second folding edge unit. The first hemming unit is formed by folding the first side inward so as to be closely attached to the outline of the core member, and attaching the first side to the first surface. The crease of the first folding edge unit extends to the corner and folds the corner, and the folding corner unit is formed by folding the folded corner inwards and attaching the folded corner to the first edge and the first surface in a mode of clinging to the outline of the core material. The second flange unit is formed by folding the second flange inward so as to be closely attached to the outline of the core material and attaching the second flange to the corner portion and the first surface.

Description

Vacuum insulation panel and insulation can Technical Field The utility model relates to the field of vacuum heat insulation, in particular to a vacuum heat insulation plate and an incubator. Background In the process of packaging the vacuum insulated panel, in order to reduce the whole volume occupation, redundant packaging outer bags around the vacuum insulated panel are required to be folded and fixed on the core material part. However, the corners of the outer bag folding structure of the existing vacuum insulation panel are not straight, and the thickness of the outer bag at the corners is larger, so that gaps are large when the vacuum insulation panels are spliced, and the loss of cold and heat is serious. Disclosure of utility model Aiming at the problems, the utility model provides a vacuum insulation board and an insulation box, which can solve the problem of serious cold and heat loss caused by large gaps in the splicing process of the vacuum insulation board. The first aspect of the present utility model provides a vacuum insulation panel comprising a core material and an outer envelope. The panel surface of the core material and the outer bag are rectangular, and the length and the width of the outer bag are larger than those of the core material so as to cover the panel surface of the core material. The panel of the core material comprises a first surface and a second surface which are oppositely arranged. The redundant part of the outer bag with the area larger than that of the core material comprises a first edge, a second edge and a corner part, wherein the corner part is positioned at the corner where the first edge is connected with the second edge, and the redundant part is attached and fixed with the core material in a form of clinging to the outline of the core material by utilizing a turnover structure. The outer bag can completely cover the board surface of the core material, and the redundant part can be attached to the corner of the core material. The folding structure comprises a first folding edge unit, a folding angle unit and a second folding edge unit. The first hemming unit is formed by folding the first side inward so as to be closely attached to the outline of the core member, and attaching the first side to the first surface. The crease of the first folding edge unit extends to the corner and folds the corner, and the folding corner unit is formed by folding the folded corner inwards and attaching the folded corner to the first edge and the first surface in a mode of clinging to the outline of the core material. The second flange unit is formed by folding the second flange inward so as to be closely attached to the outline of the core material and attaching the second flange to the corner portion and the first surface. Through the mode, the first side of the redundant part is folded to the first surface, then the corner is folded to the first side and the first surface, and finally the rest of the second side is folded to be attached to the first surface, the first side and the corner, so that the redundant part of the outer bag is flatly wrapped at the corner of the core material, gaps in the splicing process of the vacuum insulation panel are improved, and the loss of cold and heat in the using process is reduced. Optionally, the core material includes a first sidewall and a second sidewall near the corner, the first sidewall being along a length direction of the core material, the second sidewall being along a width direction of the core material.
