Abstract
The utility model relates to a vacuum insulation plate. Hollow holes penetrating the insulation plate are formed in the middle of plate-shaped heat insulating materials, reflecting films are coated on the inner walls of the hollow holes, and getters are placed into the hollow holes, so as to form the insulation plate with hollow holes; and then the insulation plate is vacuumized after being wrapped with a high barrier film with a reflecting function, so as to form the hollow holes type vacuum insulation plate.
Description
Technical field
The utility model relates in a kind of VIP vacuum heat-insulating plate, the especially vacuum heat-insulating plate and has adopted empty structure, can improve heat insulation effect, and saves thermal insulating material.
Background technique
At present, known vacuum heat-insulating plate is to add to put into sealing package behind the getter and vacuumize the process structure of sealing again in thermal insulating material, this kind vacuum heat-insulating plate requires high to thermal insulating material, and be solid construction, a large amount of air are hidden in the thermal insulating material, in working process, exist to vacuumize the comparison difficulty, need the long time, can't guarantee degree of vacuum; But also the defective of consumptive material.
Summary of the invention
The purpose of this utility model provides foregoing vacuum heat-insulating plate, and it is compared with the vacuum heat-insulating plate of prior art, and its time that vacuumizes is short, and heat-insulating property is better, but also saves thermal insulating material.
The technological scheme that its technical problem that solves the utility model adopts is: the cavity of running through warming plate is set in the middle of tabular thermal insulating material, inwall in the cavity is covered with reflecting coating, and in the cavity, put into getter, formation has the thermal shield of empty structure, with vacuumizing behind the high-isolation film parcel that reflection function is arranged, form vacuum heat-insulating plate again.
The beneficial effects of the utility model are: because the inside of the thermal shield of empty structure is hollow-core construction, a large amount of air are present in the cavity, help inner vacuum and produce, the open placement of the getter in the cavity, easier in surplus air absorption, guaranteed the degree of vacuum of vacuum heat-insulating plate; But also saved thermal insulating material.Because the empty inwall in the empty structure for vacuum thermal shield is provided with reflecting coating, blocked the approach of thermal radiation heat radiation again internally, make its heat-insulating property better.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is first embodiment's of vacuum heat-insulating plate a sectional drawing.
Fig. 2 is second embodiment's of vacuum heat-insulating plate a sectional drawing.
1. thermal insulating materials among the figure, 2. cavity, 3. reflecting coating, 4. high-isolation film, 5. getter.
Embodiment
Among the figure, vacuum heat-insulating plate is made up of with getter (5) thermal insulating material (1), interior void (2), reflecting coating (3), high-isolation film (4).The cavity (2) of running through warming plate is set in the middle of thermal insulating material (1), inner peripheral wall in cavity (2) can cover reflecting coating (3), in cavity (2) behind the open placement getter (5), the two-port in cavity (2) is sealed with thermal insulating material, the warming plate of making is placed in the bag that the high-isolation film (4) of reflection function makes, extracts and seal after a air in the bag forms vacuum.
The utility model is not limited to foregoing, shape, quantity, the arrangement in cavity, though the shape of thermal shield does not occur in the present embodiment, the vacuum heat-insulating plate that has adopted same principle is also in protection scope of the present invention.
Claims (3)
1. a vacuum heat-insulating plate is made up of thermal insulating material, cavity, reflecting coating, high-isolation film and getter, it is characterized in that: the cavity of running through warming plate is set in the middle of thermal insulating material.
2. vacuum heat-insulating plate according to claim 1 is characterized in that: the inner peripheral wall in the cavity can cover reflecting coating.
3. vacuum heat-insulating plate according to claim 1 is characterized in that: open placement getter in the cavity.
