Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, make required for being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Other technical solutions.
Fig. 1 is the structural schematic diagram according to the vacuum heat-insulating plate of one embodiment of the utility model；
Fig. 2 is the structural schematic diagram according to the aluminum membranous layer of one embodiment of the utility model.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order to make the reader understand this application better, many technical details are proposed.But even if without these skills
The required guarantor of each claim of the application also may be implemented in art details and various changes and modifications based on the following respective embodiments
The technical solution of shield.
Fig. 1 is the structural schematic diagram for vacuum heat-insulating plate according to one embodiment of the utility model.According to Fig. 2
The structural schematic diagram of the aluminum membranous layer of one embodiment of the utility model.As shown in Figure 1, vacuum heat-insulating plate includes multiple aluminum membranous layers
3 be alternately stacked with multiple glass fibre carpet veneers 2 stacked structure, the encapsulating stacked structure barrier film 1 and be arranged in glass
Getter unit 4 among glass fibre felt layer, vacuum heat-insulating plate further include being formed in 3 upper surface and lower surface of aluminum membranous layer
Aeroge carpet veneer 32 (refers to Fig. 2), and the top layer of the stacked structure and lowest level are glass fibre carpet veneer.
The aluminum membranous layer 3 can be aluminium foil, aluminizer or the film for plating aluminium foil, preferably aluminium foil.Shown in the drawings of 4 aluminium
Film layer, but can according to need the number of setting aluminum membranous layer, such as can preferably 6-8 layer.Wherein state the thickness of aluminum membranous layer
It can be 7-15um or other suitable thickness.
An embodiment according to the present utility model, wherein the aeroge is SiO2Aeroge, AL2O3Aeroge, carbon
One of aeroge and organic aerogel are a variety of.The thickness of the aeroge carpet veneer can be 1.0-1.5mm, Huo Zheqi
His suitable thickness.
Embodiment according to the present utility model, wherein the barrier film for example can be compound by PES, PVDF, multilayer aluminum

Material.Those skilled in the art should be readily appreciated that this.As shown in Figure 1, getter unit 4 setting glass fibre carpet veneer 2 it
In, naturally it is also possible to it is disposed in other locations.
There are three types of the modes of vacuum heat-insulating plate heat transmitting: thermal convection, heat transfer and heat radiation.Because internal vacuumizes place
Reason and the extremely low gap of glass fibre and high percent opening, thermal convection and heat transfer can almost completely cut off completely.This is practical new
Aluminium foil is added in type selection in core material, and aluminium foil has low heat radiation emissivity, heat radiation can be greatly reduced.Aluminium foil simultaneously
Addition can also greatly improve the pressure-resistant performance and bending resistance of vacuum heat-insulating plate, and since there is the work of aluminium foil in inside
With, so that gas infiltration needs to permeate repeatedly, the great service life for improving product.
In addition, since aluminium has biggish heat conductivity, such as Fig. 2 each attached one layer of aperture between the upper and lower level of aluminium foil 3
The all minimum aerogel blanket 32 of rate and aperture improves heat insulation and preservation effect to reduce the heat transfer inside core material.
