Description
Technical field
The utility model belongs to the industrial product field, especially is applicable to the anti-absorbing and shrinkage support device that uses in large-area vacuum insulator device.
Background technique
In the vacuum heat-insulation body device,, need to use support device to prevent to inhale flat at present in order between two-layer thermal-protective coating, to form the vacuum space.The slim vacuum heat insulator of small size does not have support usually, but common large-area flat-plate type, class is plate and the vacuum heat-insulation body device of large scale curved face type in, must there be liner material to fill or large-area support block between its vacuum sandwich, be to cause interlayer distortion or break like this for fear of negative pressure is excessive, because liner material and interlayer contact both sides face are very big, cause heat-transfer effect strong, make the vacuum heat-insulation deleterious.And these liner materials or the ununified standard of support block, in industry is used, can not make series product, thereby increase supporting manufacture cost.
Summary of the invention
The utility model purpose provides a kind of simple in structure, reduces the thermal radiation conduction, prevents heat transfer between the two-layer thermal-protective coating, can be good at forming the support device that is applied to vacuum heat insulator for preventing absorbing shrinkage of vacuum space.
The utility model adopts following technological scheme for achieving the above object:
A kind of support device that is applied to vacuum heat insulator for preventing absorbing shrinkage, comprise vacuum heat-insulation device skin, vacuum heat-insulation device internal layer, form the vacuum space between vacuum heat-insulation device skin and the vacuum heat-insulation device internal layer, between the outer and vacuum heat-insulation device internal layer of vacuum heat-insulation device several supports are set, are connected by adhesive layer between vacuum heat-insulation device skin and the support.
Support of the present utility model is truncated cone or positive terrace with edge shape, and its both ends of the surface are respectively segment sphere shape, and spherical diameter is respectively r, R, and the width of support both ends of the surface is respectively d, D, r＞5d, and R＞5D, the area of both ends of the surface is respectively S

End that support area of the present utility model is less and vacuum heat-insulation device internal layer are oppositely arranged, and the end that the support area is bigger is connected by adhesive layer with vacuum heat-insulation device skin.
The utility model adopts technique scheme, compared with prior art has following advantage:
1, support of the present utility model is made the circular cone bench-type usually, the upper and lower end face is designed to the segment sphere shape of long radius, can form very tiny surface of contact with thin-walled surface in the vacuum chamber that is subjected to high pressure, the contact of approximate point can significantly reduce the direct heat conduction of supporting between pearl and the thin-walled like this; Can also reduce support that bead carries the upper and lower end face that produces behind the high pressure collapse the limit phenomenon.It is bonding to support the suitable binder of the single-ended usefulness of pearl large end face, can guarantee the during normal use firm adhesion of vacuum heat-insulation vessel, can not come off, be not subjected to small variation of inside and outside wall spacing and moving influence yet, when playing anti-negative pressure supporting effect, reduce heat conduction efficiency, reach desirable effect of heat insulation.
2, adhesive layer of the present utility model uses and can make at the solid material that advantages of higher compressive strength is arranged that the vacuum heat insulator Maximum operating temperature can not be softened, and as phenolic resin, glass, porcelain grain, haydite, high-grade cement, cast stone etc., applicability is wide.
3, the utility model support one end face that area is less faces toward the high temperature sidewall, can reduce the thermal radiation conduction like this.
4, the utility model can be removed the original stuffing that adopts of vacuum cavity from large-area vacuum insulator device, and cost is also saved in both weight reductions, though each supporting bead small end face area is less, and about 0.03Cm
2To 0.2Cm
2,, can bear 15Cm respectively according to different material and manufacturing process
2To 150Cm
2The pressure of chamber walls area, and the contact transmission of heat between the outer chamber wall in obviously reducing.Owing to adopt supporting bead, the specification kind can seriation, standardization, is suitable for the support use of the inside and outside wall spacing difference that the inner different parts of vacuum heat-insulation device certainly leads to because of moulding and shape relation.This external manufacturing processing is gone up and is adopted mould pressing process, is fit in enormous quantities and specialized production.
5, the utility model architecture is simple.
