Abstract
The invention discloses a vacuum heat insulation panel. A cavity which runs through a heat retaining panel is arranged in the middle of a tabular heat retaining material; a reflection membrane is covered on the inner wall of the cavity, and a getter is put in the cavity, and the heat retaining panel with the cavity is formed; and after the heat retaining panel is wrapped by a high-obstruction thin film with a reflection function again, and is vacuumized, and a cavity-type vacuum heat insulation panel is formed.
Description
Technical field
The present invention relates to adopt empty structure in a kind of VIP vacuum heat-insulating plate, the especially vacuum heat-insulating plate, can improve heat insulation effect, and save thermal insulating material.
Background technique
At present; Known vacuum heat-insulating plate is in thermal insulating material, to add to put into sealing package behind the getter and vacuumize the process structure of sealing again, and this kind vacuum heat-insulating plate requires high to thermal insulating material, and is 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 invention is to provide foregoing vacuum heat-insulating plate, it is compared with the vacuum heat-insulating plate of existing technology, its time that vacuumizes is short, and heat-insulating property is better, but also saves thermal insulating material.
The technical solution adopted for the present invention to solve the technical problems 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, forms vacuum heat-insulating plate again.
The invention has the beneficial effects as follows: 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; More be prone to surplus air absorption has been 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
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
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 processes, extract and seal after a air in the bag forms vacuum.
The present invention 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)
