Description

Grid type vacuum heat insulation plate

Technical Field

The utility model relates to an heated board technical field, it is specific, relate to a latticed vacuum insulation panels.

Background

In the technical field of heat preservation, the vacuum heat insulation plate is a heat preservation product with the lowest heat conductivity coefficient at present, so the vacuum heat insulation plate can meet the heat preservation requirement with the smallest thickness, particularly, the passive ultra-low energy consumption building is rapidly developed at present, when the traditional heat insulation material is adopted in northern areas, the thickness of the heat preservation layer can be close to 30 centimeters, and when the vacuum heat insulation plate is applied, the thickness of the heat preservation layer is only 5-6 centimeters. At present vacuum insulation panels directly adopts sealed package to wrap the core because in the production process, then extracts the vacuum in evacuation equipment to seal and form, and the panel size is great, and can take place the local damaged condition of packing at application in-process occasionally, even produce a tiny hole to vacuum insulation panels, monoblock vacuum insulation panels also can take place to keep warm the problem that became invalid. The vacuum insulation panel is easy to damage and lose efficacy, so that the vacuum insulation panel is difficult to popularize and apply in a large area.

SUMMERY OF THE UTILITY MODEL

The utility model provides a grid vacuum insulation panels has solved the problem that local damage can lead to the whole inefficacy of insulation panels among the correlation technique.

The technical scheme of the utility model as follows:

including a plurality of division boards that connect gradually, it is a plurality of the division board encloses into the net that a plurality of arranged in proper order, the core has been placed in the net, be provided with the sealed package layer outside the net, its characterized in that, every the terminal surface of net all with the sealed package layer bonds, every the net is independently sealed.

The end part of the partition plate is vertically connected with the sealed package layer.

The two ends of the partition plate in the height direction are provided with combining pieces, and the combining pieces are vertically connected with the partition plate.

The two combination pieces at two ends of one partition plate are respectively positioned in two adjacent grids.

The shape of the grid is a polygon, and the number of the grid edges is more than or equal to three.

The utility model discloses a theory of operation and beneficial effect do:

the utility model discloses in, latticed vacuum insulation panels includes division board, core and sealed package layer. During manufacturing, the bonding sheet and the sealing packaging layer on the end face of one side of the partition plate are bonded, the core material is placed in a grid space formed by the partition plate, then the sealing packaging layer is covered, vacuumizing is performed, and the contact part of the partition plate and the sealing packaging layer is heated and pressed, so that an independent sealing space can be formed by each grid while the integral grid type vacuum heat insulation plate is formed. Because the core material is divided into a plurality of units by the partition plates and the sealing package layers, and each unit is in an independent sealing state, in the application process, even if the sealing package is locally damaged, the heat insulation performance of the corresponding grid can be only damaged, and the problem of heat insulation failure of other parts of the vacuum heat insulation plate can not occur, so that the damage resistance of the vacuum heat insulation plate is improved, and the wider application of the vacuum heat insulation plate is facilitated. In addition, the partition plates are arranged, so that the overall strength of the heat insulation plate can be improved, and the service life of the heat insulation plate can be prolonged.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work, are related to the scope of the present invention.

As shown in fig. 1-3, the utility model provides a latticed vacuum insulation panels, including a plurality of division boards 2 that connect gradually, a plurality of division board 2 encloses into a plurality of net 3 of arranging in proper order, has placed core 4 in the net 3, and net 3 is provided with sealed package layer 1 outward, and every net 3's terminal surface all sealed package layer 1 bonds, and every net 3 is independently sealed.

In this embodiment, the grid type vacuum insulation panel includes a separator 2, a core material 4, and a seal packing layer 1. During manufacturing, a sealing package layer 1 is covered on one side of a partition plate 2, one end face of the partition plate 2 is bonded with the sealing package layer 1, a core material 4 is placed in a space of a grid 3 formed by the partition plate 2, then the sealing package layer 1 is covered, vacuumizing is performed, and the contact part of the partition plate 2 and the sealing package layer 1 is heated and pressed, so that an integral grid type vacuum heat insulation plate is formed, and meanwhile, each grid 3 can form an independent sealing space. Because division board 2 and sealed package layer 1 have cut apart into a plurality of unit with core 4, and every unit all is in independent sealed state, in the application, even sealed package layer 1 has taken place the damage locally, also can only destroy the thermal insulation performance of the net that corresponds, and the problem that the heat preservation became invalid can not appear in the other parts of vacuum insulation panel to improve vacuum insulation panel's anti destructive power, be favorable to vacuum insulation panel's more extensive application. In addition, by arranging the partition plate 2, the overall strength of the heat insulation plate can be improved, and the service life of the heat insulation plate can be prolonged.

Furthermore, the two ends of the partition board 2 in the height direction are both provided with a combination piece 6, and the combination pieces 6 are vertically connected with the partition board 2.

In this embodiment, in order to increase the area of the bonding surface between the two ends of the partition plate 2 and the sealing wrapper 1, the bonding sheets 6 are disposed at the two ends of the partition plate 2 in the height direction, i.e., at the openings at the two ends, the bonding sheet 6 at one end of the partition plate 2 is connected to the sealing wrapper 1 by bonding, and the bonding sheet 6 at the other end is connected to the sealing wrapper 1 by adhesive-heat sealing. The combining piece 6 is perpendicular to the separation plate 2.

Further, two bonding pieces 6 at both ends of one partition plate 2 are respectively positioned in two adjacent grids 3.

In this embodiment, two of a division board 2 both ends combine the piece 6 the opposite direction of buckling to make two combine the piece to be located adjacent two different net 3, set up like this and can more even arrange and combine piece 6, improve the bulk strength.

Further, the shape of the mesh 3 is a polygon, and the number of the sides of the mesh 3 is not less than three.

In this embodiment, the shape of the grid 3 may be various, such as triangle, rectangle, diamond, hexagon, etc., as long as the core materials 4 can be arranged in sequence and form a cavity. In order to facilitate production, the rectangular or regular hexagon can be optimally selected, so that the die opening is facilitated, and the cost is saved.
